Jar file execution

hi all
can anyone one tell me the procedure of how to create a executable jar file.
on clicking on the jar file itself my class file has to be executed without executing it from command prompt.
thanks in advance

Jar file execution fails

Hi,
May be somebody has an idea about my problem.
I have vendor jar file; Notes.jar with class lotus.notes.NotesThread.class
Now I'm trying to create an instance of NotesThread in my class CustomAgent.
Problem is: when I run just the class: java CustomAgent, it works.
But if I created jar file by jar -cf custom.jar *.class and try to execute it by java -jar custom.jar, it fails and gives me an error:
Exception in thread "main" java.lang.NoClassDeffoundError: lotus/notes/NotesThread
Does anybody have any clue?
Thanks a lot

Create a manifest file with the Main-Class property in it.
Main-Class: MyClass
And then create the jar file using the manifest.
jar -cmf mymanifest myjar.jar /workingdir/*.class
Now your jar file will be executable.
Because you are using an external jar file.
Make sure the manifest file also has
the "Class-Path: external1.jar external2.jar"
If you put those external.jar files in the same directory as your jar files you should be okay.
Happy programming.

Jar file execution problem

Hello friends,
I have a project folder in which i have 4 packages
application
ui
controller
model and
a folder Datafile containing project related xml and text files
my main class is in application package
I am creating a jar file of my whole project folder in Eclipse environment, using the main class as TheApplication in application package. I am able to generate the jar file but unable to execute it.
When I tried to execute it from command prompt it is giving me an error saying no main,
Please tell me what I am doing wrong, and suggest me a solution
Thanks in advance

ya, You are required to put an entry in Malifest file.
you need to add Main-Class <your class name with which you need to start ur application
Wasn't this already shown in reply #7?> Yes it was, But as he said, even though he is getting the same problem.. So. I tried to recall him that, that class should the starting point to the application & it should be public & it should have public method.. And is not mentioned in that reply #7
I guess you got my point now.

Hello All,
I'm making a Java SQL Client. I have practicaly all basic work done, now I'm trying to improve it.
One thing I want it to do is to allow the user to specify new drivers and to use them to make new connections. To do this I have this class:
public class DriverFinder extends URLClassLoader{
private JarFile jarFile = null;
private Vector drivers = new Vector();
public DriverFinder(String jarName) throws Exception{
super(new URL[]{ new URL("jar", "", "file:" + new File(jarName).getAbsolutePath() +"!/") }, ClassLoader.getSystemClassLoader());
jarFile = new JarFile(new File(jarName));
System.out.println("-->" + System.getProperty("java.class.path"));
System.setProperty("java.class.path", System.getProperty("java.class.path")+File.pathSeparator+jarName);
System.out.println("-->" + System.getProperty("java.class.path"));
Enumeration enumeration = jarFile.entries();
while(enumeration.hasMoreElements()){
String className = ((ZipEntry)enumeration.nextElement()).getName();
if(className.endsWith(".class")){
className = className.substring(0, className.length()-6);
if(className.indexOf("Driver")!=-1)System.out.println(className);
try{
Class classe = loadClass(className, true);
Class[] interfaces = classe.getInterfaces();
for(int i=0; i<interfaces.length; i++){
if(interfaces.getName().equals("java.sql.Driver")){
drivers.add(classe);
Class superclasse = classe.getSuperclass();
interfaces = superclasse.getInterfaces();
for(int i=0; i<interfaces.length; i++){
if(interfaces[i].getName().equals("java.sql.Driver")){
drivers.add(classe);
}catch(NoClassDefFoundError e){
}catch(Exception e){}
public Enumeration getDrivers(){
return drivers.elements();
public String getJarFileName(){
return jarFile.getName();
public static void main(String[] args) throws Exception{
DriverFinder df = new DriverFinder("D:/Classes/db2java.zip");
System.out.println("jar: " + df.getJarFileName());
Enumeration enumeration = df.getDrivers();
while(enumeration.hasMoreElements()){
Class classe = (Class)enumeration.nextElement();
System.out.println(classe.getName());
It loads a jar and searches it looking for drivers (classes implementing directly or indirectly interface java.sql.Driver) At the end of the execution I have found all drivers in the jar file.
The main application loads jar files from an XML file and instantiates one DriverFinder for each jar file. The problem is at execution time, it finds the drivers and i think loads it by issuing this statement (Class classe = loadClass(className, true);), but what i think is not what is happening... the execution of my code throws this exception

I have tried also (as you can see in comented lines) to update System property java.class.path by adding the path to the jar but neither...
I'm sure I'm making a/some mistake/s... can you help me?
Thanks in advice,

Execution from JAR files and Classpaths -- Help

I am confused about how classes are resolved when running from within a JAR file, and why this is different than running a class that is not inside a JAR file.
I have an application that uses classes from a third party library stored in a JAR file (biojava.jar) . If I run the app from the class file it works as expected and is capable of finding the external classes when the path to the biojava.jar is on my classpath. It also works if biojava.jar is instead placed in the extensions folder jre/lib/ext folder without an explicit path entry in my classpath.
However when I package all my application classes up in a JAR file and try to execute the application from the JAR file it will ONLY work if I add a manifest entry to myApp.jar ... Class-Path: biojava.jar AND I place the file biojava.jar in the SAME directory as the Packaged JAR application. I would like to find a way to make this JAR file work for anyone who has biojava.jar in their classpath or ext directory. In other words I don't want my user community to have to copy the biojava.jar file when I email them myApp.jar. This community will already have biojava.jar on their CLASSPATH.
How can I make my app within a JAR recognize either the user's CLASSPATH or ext folder? I have tried reading the documentation and many experiments but the only way it works is as described above.
I am running Running Windows 2000.
java version "1.4.1_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_01-b01)
Java HotSpot(TM) Client VM (build 1.4.1_01-b01, mixed mode)
Here are the results of my experimentations:
The following Works:
Manifest: Main-Class: org/biojava/app/SequenceSpiral
Manifest: Class-Path: biojava.jar
Place biojava.jar in the same directory as SequenceSpiral.jar
java -jar SequenceSpiral.jar
This works perfectly
NONE of the following work
0) Placing biojava.jar in my jre/lib/ext directory instead of the same dir as SequenceSpiral.jar
Exception in thread "main" java.lang.NoClassDefFoundError: org/biojava/bio/seq/FeatureFilter
(this is the first class referenced from biojava.jar)
1) Just see if it will find the proper jar on my classpath
Manifest: Main-Class: org/biojava/app/SequenceSpiral
I have biojava.jar on my classpath but not in same directory as SequenceSprial.jar
java -jar SequenceSpiral.jar
Exception in thread "main" java.lang.NoClassDefFoundError: org/biojava/bio/seq/FeatureFilter
2) Specify the name if the jar in the Manifest Classpath and see if it will find the proper jar on my classpath
Manifest: Main-Class: org/biojava/app/SequenceSpiral
Manifest: Class-Path: biojava.jar
I have biojava.jar on my classpath but not in same directory as SequenceSprial.jar
java -jar SequenceSpiral.jar
Exception in thread "main" java.lang.NoClassDefFoundError: org/biojava/bio/seq/FeatureFilter
3) Specify the path of the jar in the Manifest Classpath
Manifest: Main-Class: org/biojava/app/SequenceSpiral
Manifest: Class-Path: d:/biojava/biojava.jar
I have biojava.jar on my classpath (D;\biojava\biojava.jar) but not in same directory as SequenceSprial.jar
java -jar SequenceSpiral.jar
Exception in thread "main" java.lang.NoClassDefFoundError: org/biojava/bio/seq/FeatureFilter
(note that in this case it is not fnding my main even though the Main-Class is specified)
4) Specify current directory and biojava.jar in the Manifest Class-Path
Manifest: Main-Class: org/biojava/app/SequenceSpiral
Manifest: Class-Path: .;biojava.jar
I have biojava.jar on my classpath (D;\biojava\biojava.jar) but not in same directory as SequenceSprial.jar
java -jar SequenceSpiral.jar
Exception in thread "main" java.lang.NoClassDefFoundError: org/biojava/bio/seq/FeatureFilter
5)Specify current directory and the URL of biojava.jar in the Manifest Class-Path
Manifest: Main-Class: org/biojava/app/SequenceSpiral
Manifest: Class-Path: . d:/biojava/biojava.jar
I have biojava.jar on my classpath (D;\biojava\biojava.jar) but not in same directory as SequenceSprial.jar
java -jar SequenceSpiral.jar
Exception in thread "main" java.lang.NoClassDefFoundError: org/biojava/bio/seq/FeatureFilter.
Thank you very much for any help or suggestions,

I did some more testing and I think I now understand what is going on.
I don't like it, but at least I understand it.
The problem: I have an app packaged into a JAR file, myApp.jar. It has a dependancy upon an external JAR file extern.jar.
extern.jar is on my Classpath (and also in jre/lib/ext)
1) For some reason (bug?) java -jar myApp.jar does NOT use the classpath or the jre/lib/ext mechanisms to find .jar files needed to resolve references to external classes. This seems to be true even if you add an explicit -classpath argument on the command line!
thus
java -jar -cp c:\\absolutePathToMy\extern.jar myApp.jar
also fails as does
java -cp c:\\absolutePathToMy\extern.jar -jar myApp.jar
2) Inside the myApp Jar file you can specify a URL to an jar extension jar file but the URL IS RELATIVE TO THE PATH WHERE THE myApp.Jar is executed from! If I add the Manifest item Class-Path: ..\..\..\myexterndir\extern.jar then
java -jar myApp.jar
works correctly and resolves the external references.
This is why several people have reported that this class-path mechanism works ONLY when the extern.jar file is in the SAME DIRECTORY as the myApp.jar file when they had added a Class-Path: extern.jar to the Manifest.
However together these two items make it IMPOSSIBLE to distribute myApp.jar to others and have it work since the path names statically encoded inside the jar are relative to where the jar gets executed from. If I move myApp.jar to a different location on my hard drive it may also fail.
In my case I know all my customers already have extern.jar (5MB) installed on their classpaths and I would like to just send them the myApp.jar ( .5MB ).
However I don't see how to do this given the current specification of a JAR file, and the bug that makes all -jar file act like they have the Sealed=true property.
I tried explicity setting Sealed=false in the manifest but this didn't seem to have any effect.
I hope that this will save others the many hours of time it has taken be to determine that JARS are not well suited for deploying apps with dependenncies on external libs.
I also hope that someone can show me how execute a JAR and specify a classpath that doesn't get IGNORED my the classloader used in loading the jar classes.
This is using java version:
java version "1.4.1_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_01-b01)
Java HotSpot(TM) Client VM (build 1.4.1_01-b01, mixed mode)
Does any one know this bug is fixed in a later release?

NAME
jar - Java archive tool
SYNOPSIS
jar [ -C ] [ c ] [ f ] [ i ] [ M ] [ m ] [ O ] [ t ] [ u ]
[ v ]
[ x file ] [ manifest-file ] destination input-file
[ input-files ]
DESCRIPTION
The jar tool is a Java application that combines multiple
files into a single JAR archive file. It is also a gen-
eral-purpose archiving and compression tool, based on ZIP
and the ZLIB compression format. However, jar was
designed mainly to facilitate the packaging of Java
applets or applications into a single archive. When the
components of an applet or application (.class files,
images and sounds) are combined into a single archive,
they can be downloaded by a Java agent (like a browser) in
a single HTTP transaction, rather than require a new con-
nection for each piece. This dramatically improves down-
load time. The jar tool also compresses files, which fur-
ther improves download time. In addition, it allows indi-
vidual entries in a file to be signed by the applet author
so that their origins can be authenticated. The syntax
for the jar tool is almost identical to the syntax for the
tar(1) command. A jar archive can be used as a class path
entry, whether or not it is compressed.
The three types of input files for the jar tool are:
o Manifest file (optional)
o Destination jar file
o Files to be archived
Typical usage is:
example% jar cf myjarfile *.class
In this example, all the class files in the current direc-
tory are placed in the file named myjarfile. A manifest
file is automatically generated by the jar tool and is
always the first entry in the jar file. By default, it is
named META-INF/MANIFEST.MF. The manifest file is the
place where any meta-information about the archive is
stored. Refer to the Manifest Format in the SEE ALSO sec-
tion for details about how meta-information is stored in
the manifest file.
To use a pre-existing manifest file to create a new jar
archive, specify the old manifest file with the m option:
example% jar cmf myManifestFile myJarFile *.class
When you specify cfm instead of cmf (that is, you invert
the order of the m and f options), you need to specify the
name of the jar archive first, followed by the name of the
manifest file:
example% jar cfm myJarFile myManifestFile *.class
The manifest uses RFC822 ASCII format, so it is easy to
view and process manifest-file contents.
OPTIONS
The following options are supported:
-C Changes directories during execution of the jar com-
mand. For example:
example% jar uf foo.jar -C classes *
c Creates a new or empty archive on the standard out-
put.
f The second argument specifies a jar file to process.
In the case of creation, this refers to the name of
the jar file to be created (instead of on stdout).
For table or xtract, the second argument identifies
the jar file to be listed or extracted.
i Generates index information for the specified jar
file and its dependent jar files. For example,
example% jar i foo.jar
would generate an INDEX.LIST file in foo.jar which con-
tains location information for each package in foo.jar and
all the jar files specified in foo.jar's Class-Path
attribute.
M Does not create a manifest file for the entries.
m Includes manifest information from specified pre-
existing manifest file. Example use:
example% jar cmf myManifestFile myJarFile *.class
You can add special-purpose name-value attribute
headers to the manifest file that are not contained
in the default manifest. Examples of such headers
are those for vendor information, version informa-
tion, package sealing, and headers to make JAR-bun-
dled applications executable. See the JAR Files
trail in the Java Tutorial and the JRE Notes for
Developers web page for examples of using the m
option.
O Stores only, without using ZIP compression.
t Lists the table of contents from standard output.
u Updates an existing JAR file by adding files or
changing the manifest. For example:
example% jar uf foo.jar foo.class
adds the file foo.class to the existing JAR file
foo.jar, and
example% jar umf foo.jar
updates foo.jar's manifest with the information in
manifest.
v Generates verbose output on stderr.
x file
Extracts all files, or just the named files, from
standard input. If file is omitted, then all files
are extracted; otherwise, only the specified file or
files are extracted.
If any of the files is a directory, then that direc-
tory is processed recursively.
EXAMPLES
To add all of the files in a particular directory to an
archive:
example% ls
0.au 3.au 6.au 9.au at_work.gif
1.au 4.au 7.au Animator.class monkey.jpg
e.au 5.au 8.au Wave.class spacemusic.au
example% jar cvf bundle.jar *
adding: 0.au
adding: 1.au
adding: 2.au
adding: 3.au
adding: 4.au
adding: 5.au
adding: 6.au
adding: 7.au
adding: 8.au
adding: 9.au
adding: Animator.class
adding: Wave.class
adding: at_work.gif
adding: monkey.jpg
adding: spacemusic.au
example%
If you already have subdirectories for images, audio
files, and classes that already exist in an HTML direc-
tory, use jar to archive each directory to a single jar
file:
example% ls
audio classes images
example% jar cvf bundle.jar audio classes images
adding: audio/1.au
adding: audio/2.au
adding: audio/3.au
adding: audio/spacemusic.au
adding: classes/Animator.class
adding: classes/Wave.class
adding: images/monkey.jpg
adding: images/at_work.gif
example% ls -l
total 142
drwxr-xr-x 2 brown green 512 Aug 1 22:33 audio
-rw-r--r-- 1 brown green 68677 Aug 1 22:36 bundle.jar
drwxr-xr-x 2 brown green 512 Aug 1 22:26 classes
drwxr-xr-x 2 brown green 512 Aug 1 22:25 images
example%
To see the entry names in the jar file using the jar tool
and the t option:
example% ls
audio bundle.jar classes images
example% jar tf bundle.jar
META-INF/MANIFEST.MF
audio/1.au
audio/2.au
audio/3.au
audio/spacemusic.au

Class-Path: buy.jar sell.jar other.jar
then you can use the i option to speed up your applica-
tion's class loading time:
example$ jar i main.jar
An INDEX.LIST file is inserted in the META-INF directory
which will enable the application class loader to download
the right jar files when it is searching for classes or
resources.

Images are not comming out when application is running through jar file.

I have written an application program using j2sdk1.4.1 that needs your help.
My application folder's contents.....................................................................................
     C:\Examination\Examination.class <-----This is the main class and application's entry point.
     C:\Examination\ExamBox.class
     C:\Examination\PaperSetterBox.class
     C:\Examination\pspBox.class
     C:\Examination\epBox.class
     C:\Examination\TimerBox.class
     C:\Examination\ReportCardBox.class
     C:\Examination\HelpBox.class
     C:\Examination\AboutBox.class
     C:\Examination\Images\(some jpg & gif files)
     C:\Examination\Sounds\(some au files)
Compilation Report:     There was no error.
Execution Report :     Was working properly using the command:- java Examination
Now, I created a jar file for my application in the following steps.................................
          STEP-1:          Firstly, I created a text file(mainclassInfo.txt) that contains
          the line:--     Main-Class: Examination
          This line would be automatically added to the default manifest file when I would include the                name of that text file with the command to create the jar file.
          Location of the text file I created:     C:\mainClassInfo.txt
          STEP-2:          Then I went to C:\Examination and executed the following command(by using                'Command prompt'):--------------------------------------------------------------------
jar cmf C:\mainClassInfo.txt Examination.jar Examination.class ExamBox.class PaperSetterBox.class pspBox.class epBox.class TimerBox.class ReportCardBox.class HelpBox.class AboutBox.class Images Sounds
Finally, I got the jar file:-     Examination.jar
Double clicking on it application ran as it was expected.
Then, I thought, that as all the files & folders the application needed to run properly were packaged in the jar file; I should delete all the contents of the folder 'Examination', so that no one could see or use anything of the resources easily. I did that.
So, then it became only:-- C:\Examination\Examination.jar
Thereafter, I tried to run the application again and there a problem occurred! The application was running, but the images, those were to be used and shown by the application were missing somehow!!
Moreover, when I kept a copy of those 2 folders('Images' and 'Sounds') into the C:\Examination and ran the application again all the images came out normally!
I just can't understand why it's happening so mysterious?
I don't want to leave anything of the resources in an open place; I mean, outside of the jar file. The images should be used and shown by the application.
Help me please!

The Image class itself does not have any methods for loading images from files so you must be using something more. Most methods for loading images from files have an overload that lets you use a URL, so you just need to use that method with a call to getResource like in the other thread. If you can't think of anything else, you can use ImageIcon to load an Image (the Image is returned by a call to ImageIcon.getImage). See also "how to use icons" from the swing tutorial:
http://java.sun.com/docs/books/tutorial/uiswing/misc/icon.html

How to call a jar file from oracle forms (6i)

Hi,
I'm working with oracle 6i. I want to know that how to call a .jar file from forms menu. when I use HOST('<path>\test.jar') it is working in 'Client Server' any way. but the problem is I use application server in order to run my form. so my form is in the server and I run the form via clients web browser. in that case above solution will not work. if any body knows how to overcome this problem please reply.
thanks.
duminda

I created a bean area and set the class name as implementation class. within that java bean class I called to a bat file which consists of the execution command of the jar file ( because i don't know how to call .jar file from my bean class directly).
then i tried to run it in application server. its still not running.
can you tell me what i have to do within my bean class? or can you suggest any solution?
thank you.

Problems with signed JAR files in JWS/JRE6 environment.

Hello All,
I'm encountering a problem running our desktop application as a Java Web Start deployment in a JRE 6 environment. There were never any problems when running the same application as a JWS deployment in JRE 1.4, or 5, environments. There are also currently no problems in a JRE 6 environment when running the application as a standard desktop application.
The problem which I am having has nothing to do with launching the application. But for good measure, I verified the JNLP file with JaNeLA. A couple things we out of order, which I addressed to make JaNeLA happy, but my problem still persists. Here is my JNLP file (anonymized to protect the innocent):

The classes of our desktop product are contained within the 'acmedesktop' and 'acmeapi' packages. It requires access to the hard drive of the workstation, and therefore, all jar files included with the application are signed using the following ANT task when compiled:
<signjar keystore="resources/codesigning/keystore.pfx" storetype="pkcs12" storepass="myPassword" alias="myAlias">
     <fileset dir="${jws_dist}/app" includes="*.jar"/>
     <fileset dir="${jws_dist}/app/lib" includes="*.jar" excludes="jhall__V${dt_version}.jar"/>
</signjar>-----
Therefore, all classes, within all jar files, are signed with the same certificate (with the exception of the JavaHelp libraries, which are already signed by Sun - but the class in question attempting to be loaded here is not contained within the JavaHelp jar file anyway). So, the point being, that the exception message stating that the "signer information of the acmeapi.communication.CDocImpl class doesn't match the signer information of other classes in the same package", is simply not correct. All classes within that jar file were signed using the same certificate.
I downloaded the JRE 6 source from dev.java.net and picked through this issue with a debugger. The ClassLoader.checkCerts() method compares the certificate used to sign the current class which is attempting to be loaded, with the certificates which signed all other previously loaded classes within the same package. If they don't match, the exception above is thrown. What is causing the issue is when the checkCerts() method attempts to get the certificates which signed the currently loading class, null is returned. And obviously, comparing null, with an array of the certificates which signed the previously loaded classes, isn't going to match; therefore this exception is thrown.
The checkCerts() method gets the certificates of the currently loading class by calling the java.security.CodeSource.getCertificates() method. Tracing deeper in the debugger, the CodeSource object ultimately gets the certificates from the 'signersRef' member variable of the com.sun.deploy.cache.CachedJarFile class. signerRef is a SoftReference object and can therefore be garbage collected at some point. If it has already been garbage collected, the CachedJarFile class will attempt to retrieve it again from the loaded cache entry by calling com.sun.deploy.cache.MemoryCache.getLoadedResource().
The MemoryCache class maintains the cache entries to the jar files as MemoryCache.CachedResourceReference objects, which subclass WeakReference, and therefore these objects can be garbage collected as well. If the cache entries have also been garbage collected, this leaves the CachedJarFile class with no ability to repopulate the CachedJarFile.signerRef object. Therefore it is completely out of luck getting the certificates which signed the currently loading class, which ultimately causes the above exception.
When the com.sun.deploy.cache.Cache class attempts to retrieve a cache entry using its getCacheEntry() method, it will attempt to get the entry from the MemoryCache class, if null is returned, it will recreate the cache entry and add it back to the MemoryCache. In contrast, when the CachedJarFile class attempts to get a cache entry from the MemoryCache class, if null is returned, it just gives up.
(from com.sun.deploy.cache.CachedJarFile:244)
private CacheEntry getCacheEntry() {
     /* if it was not created by Cache do not search for entry */
     if (resourceURL == null)
          return null;
     CacheEntry ce = (CacheEntry) MemoryCache.getLoadedResource(resourceURL);
     if (ce == null) {
          //This should not happen because CacheEntry should not get collected
          // before CachedJarFile is collected.
          Trace.println("Missing CacheEntry for " + resourceURL + "\n" + ce,
               TraceLevel.CACHE);
     return ce;
When debugging, code execution falls within the code block with the comment stating "This should not happen...", but it is happening in my case.
On an interesting side note, using the jvisualvm.exe tool included with JDK 6, I was able to tell that it seems as though these objects are collected the first time that the JVM allocates more heap space, and then the issue will occur. If I set the initial heap size very large (using -Xms) this issue won't occur at all. But that is kind of a bad solution which I would rather not do, but it is interesting to note for the sake of troubleshooting this issue. The max heap size (-Xmx) is plenty big enough, so the issue is not that we are running out of memory here.
Does anyone have any insight as to what could be causing this? I've searched, and found a couple threads with similar problems but with no clear solutions. It is not just one workstation either, it happens everywhere I deploy the app as a Java Web Start application in a JRE 6 environment. I have been using version 1.6.0_18 on XP, but it seems to happen on any update version of 1.6. Is the fact that the CachedJarFile class doesn't attempt to reload the resource when it can't retrieve it from MemoryCache a bug? I've dug as deep as I can on this and I'm at wits end, does anybody have any ideas?
Thank you
Jake

Oracle 9i: Help with loadjava jar files to call out web service from pl/sql

Error in deploying .jar file from JDeveloper 10.1.3.5

Hello,
I want to deploy .jar file in a machine, instead of having to install JDeveloper to run the application (it contains: Web Services and Data Base).
I have followed the following steps in JDeveloper to create the .jar file:
1) Right click over the project: New... --> General (All Technologies option selected) --> Deployment Profiles --> JAR File
2) I have selected "Include Manifest File" option specifying the application's main class
3) In JAR Deployment Profile Properties window: File Groups --> Project Output --> Contributors are selected: "Project Output Directory" and "Project Dependencies"
4) With the previous steps, JDeveloper generates a .deploy file. It is created in Resources folder. From this folder, I have selected the .deploy file and right click and I have selected "Deploy to JAR file"
The .jar is created succesfully. In this point, I try to execute with the command:
java -jar NAME_OF_THE_DIRECTORY_WHERE_THE FILEIS_DEPLOYED\NameFile.jar
and I have the following error:
Exception in thread "main" java.lang.NoClassDefFoundError: javax/xml/rpc/ServiceFactory
at project.proxy.AccountClient.<init><AccountClient.java>
at project.proxy.AccountClient.main<init><AccountClient.java>
The Manifest File content is:
Manifest-Version: 1.0
Created-By: Oracle JDeveloper 10.1.3.5.0
Main-Class: project.proxy.AccountClient
I have tested with differents variables to create the .jar file, but always the error is the same. And I haven't found information to solve it. For this reason, I appreciate any help.
Thank you and regards.

If you are just building a client that access a Web service you need a JAR and not a WAR.
Ok!
One thing to try is look at the command line that JDeveloper uses to run your client (it's in the log window) - specifically look at the classpath used.
Then try and run the same thing from a command line and see if it works.
Nowadays, the application is running with a .BAT file, it contains the statement released from the JDeveloper console, and it is working perfectlly.
I try to do the same from a command line, and it works too.
Assuming it is - you can either use that, or you'll need to make sure that your JAR includes all the mentioned jars that were in the class path - this is done through the library type file group.
To create the .JAR file I have choosen the following options (JAR Deployment Profile Properties):
1) Include Manifest File --> I have selected the class that contains the main class (from the Browse option)
2) I left the default File Groups (Project Output) --> it has: Project Output Directory + Project Dependencies
3) As you said me, I have created a new File Group (type: Libraries) --> and here, I have selected all the possible Contributors. These match those specified in the project (Oracle XML Parser v2, J2EE, JAX-RPC Client, Commons Logging 1.0.3, Ojdbc14.jar).
4) Deployment to JAR File successfully.
The resulting MANIFEST.MF is:
Manifest-Version: 1.0
Created-By: Oracle JDeveloper 10.1.3.5.0
Main-Class: project.proxy.Execution
It hasn't definied "Class-Path", althought to especified a new File Group with the libraries... Is it an error?
If I extract the .JAR file, I see all libraries, and I have two folders: one with .class files of my project and other one is META-INF with MANIFEST.MF file.
5) From command line I executed:
C:\jdevstudio10135\jdk\bin > java -jar C:\jdevstudio10135\jdev\mywork\project\project\deploy\NameFile.jar
And the result is an error:
Exception in thread "main": java.lang.NoClassDefFoundError: javax/xml/rpc/ServiceFactory
I think the error is because it can not find the library ServiceFactory, but it is especified inside JAX-RPC Client library. What is wrong?
*6)* I have tried too to insert in "JAR Deployment Profile Properties" (in JAR options) an additional Manifest File to merge into MANIFEST.MF, to include "Class-Path" with all libraries's project (the same JAR from the statement released from the JDeveloper console), but I think that it is a limit, because if I insert all libraries the "Class-Path" doesn't inserted in MANIFEST.MF. The maxim is:
Class-Path: C:\jdevstudio10135\jdev\mywork\project\project\classes C:\jdevstudio10135\lib\xmlparserv2.jar C:\jdevstudio10135\lib\xml.jar C:\jdevstudio10135\j2ee\home\lib\activation.jar C:\jdevstudio10135\j2ee\home\lib\ejb.jar C:\jdevstudio10135\j2ee\home\lib\jms.jar C:\jdevstudio10135\j2ee\home\lib\jta.jar C:\jdevstudio10135\j2ee\home\lib\mail.jar C:\jdevstudio10135\j2ee\home\lib\servlet.jar C:\jdevstudio10135\webservices\lib\jaxrpc-api.jar
The following libraries afther the previous one aren't allowed to include because I think that is exceeding the maximum size.
I have tested to create various MANIFEST.MF with different PATHs libraries, but it isn't work to include in the MANIFEST.MF file all libraries...

With this .MF file (or including only "C:\jdevstudio10135\jdev\mywork\project\project\classes") I have solved the other problem (not found the libraries), but it still not working, the error is a little different:
Exception in thread "main": java.lang.NoClassDefFoundError: project/proxy/Execution
The path where the main class is: C:\jdevstudio10135\jdev\mywork\project\project\classes\project\proxy\Execution.class
I have tried to insert directlly the following paths in "Main Class" option of "Include Manifest File":
C:\jdevstudio10135\jdev\mywork\project\project\classes\project\proxy\Execution
C:\\jdevstudio10135\\jdev\\mywork\\project\\project\\classes\\project\\proxy\\Execution
And with these values, the error is the same: Exception in thread "main": java.lang.NoClassDefFoundError
I am not sure if the error is a bug of JDeveloper 10.1.3.5 or it is something that I don't correctly. Any idea?
Thank you again and regards.

Protecting the jar files from being web access

I have a jnlp file which is put under tomcat webapps folder, say (\webapps\TEST\launch.jnlp), with the jar and lib files put in the subfolder (\webapps\TEST\folder1\*.jar AND \webapps\TEST\folder1\lib\*.jar).
My question is how can i prevent user from direct access to the jar files via typing http://www.someip.com/TEST/folder1/main.jar ? I tried the following methods but it seemed not working:
1. Change the folder permisson in \webapps\TEST\*.*, but when user type the above hyperlink they can still get the jar file
2. put the jar and related files under \WEB-INF\, but now this time running the launch.jnlp, it returns an error saying that it can't access/find the WEB-INF.
Is there any method? Or should I say, when you published jnlp to web, the related jar files are forced to be accessed by everyone.

Sounds easy to me: encrypt your xml, then instead of just storing your key as plain bytes do some reversable operations on it (xor masks, reversions, whatever you like), just do them in many different points (and classes) of your code, have some parts done by methods that actually check application is running under JWS with proper codebase, scramble it all, and suddently the whole stealing operation won't be worth the effort. Obviously you should have many private (and package protected) methods, seal packages and so on. Maybe, somehow, you can even use reflection to identify calling classes (not sure, never looked for anything similar).
What else? write down some c++ code into your own dll/JNI library and make it do something too, so they'll even need to decompile the dll. If you know first execution is always online you can send another xor key and store it with persistence service or write it down to windows registry. You can keep making it harder as much as you like, even just with silly code like
Math.ceil((new GregorianCalendar.getField(Calendar.YEAR)%2000)/1000)*((int)('c'-'a'))just to retrieve the number 2. If you distribute such code through many lines and methods, once you scramble it, most people will give up.
Bye.

Which jar file(s) from the Eclipse plug-in to use

Post Author: supermonkey
CA Forum: JAVA
Hi,I downloaded JRC plug-in and realized there are 47 jar files for CR. Now I'm wondering how many of these 47 files are being use when running CR from Java? My Java application resides on a server and users access the application thru web start. If users have to download all 47 jar files every time they run the application, it would su*k for them very much. Now does anyone know which jar files are actually being use during execution?The document here http://support.businessobjects.com/communityCS/TechnicalPapers/cr_xi_r2_jrc_deployment.pdf.asp told me that I only need about 20 or so of them. I plugged into the classpath or my test application and errors occurred.

Or are all them have to be present? thanks,

Hi Ted,Thanks for the reply. But what I was interested in knowing was how many of the Eclipse-CR plugin jar files does CR require for a successful execution? Or do I have to import all 47 jar files? thanks
