Do I need toload external jars

Hi All,
I am using hssf API (org.apache.poi.hssf.usermodel.HSSF) which is nothing but API for writing into Excel sheet.
I have created a jar file using Eclipse when I run the same jar file from command prompt I get the error
C:\New Folder>java -jar TextToXls.jar
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/poi/hssf/
sermodel/HSSFWorkbook
at JavaTxtXls.<init>(JavaTxtXls.java:14)
at JavaTxtXls.main(JavaTxtXls.java:34)
I guess its not able to load jar files associated with HSSF ..so can anyone please tell me how to rectify it..
I mean to say how do we add external jars with the jar which we wish to execute by double click..
One of my friend asked me to create a batch File and set classpath during runtime and then call the java file..any better solutions..

You have to add the relative path to your external jar in your manifest.
For example, when you create a jar file, it has a META-INF folder. Inside this folder, you will find a manifest.MF file. Open it with a text editor and it should look like:
Manifest-Version: 1.0
Main-Class: YourMainClass
Then, you add a new line to show where is your external jar:
Manifest-Version: 1.0
Main-Class: YourMainClass
Class-Path: externalLibrary.jar
Note that in this case, your external jar should be in the same directory as your jar application.

Problem using Jar to include external jars in an application

Ok so, I've just completed a project, and i want to be able to jar it up so its executable by just using the jar file. I can do this, and it will load the first screen. However, i used eclipse to develop it so I just added two files to the eclipse path and it all worked. But when I jar up my application (and include the two external jars in my app), and try to use any class that needs the external jar, it dies and says java.lang.NoClassDefinitionError: javax/servlet/http/HttpServlet
How do i set it up so it actually finds the classes in the external jar?? Its fairly important that i get this to work :)

If this app is not running as part of Tomcat, you have two options. One, as ejp pointed out, is to put the missing jars into your $JAVA_HOME/lib/ext dir. If you've already tried that and it's not working, then the jars your putting there do not have the necessary classes in them. Use 'jar -tf <jarname>' to see a list of the classes in the jar.
The second approach, which it sounds like you've already tried, is using the Class-Path entry in the Manifest file. You must make sure that the jar you're referencing (servlet.jar) has the missing classes in it, and that the jar is in the same directory as the application jar. Another potential gotcha with this approach is to make sure that the jar is not indexed (they're not indexed by default).

Help need in Adding External jar files.

Hi all,
Iam developing ADF application using JDEV 11.1.1.3.0.
I need to move files from one directory to another so i have used external jar "commons-io-1.4.jar" file.
i did this by going to the project properties -->Libraries and Classpath -->Add Library
added the jat file.
In java class i have used the function
File.copyFileToDirectory(reQueueFile, TargetLocation,false);
it was working fine when i tried in IntegratedWeblogic server but when i deploy in Standalone Weblogic server its not getting the jar file.
Its throwing me the exception
javax.el.ELException: java.lang.NoSuchMethodError: org/apache/commons/io/FileUtils.moveFileToDirectory(Ljava/io/File;Ljava/io/File;Z)V
at com.sun.el.parser.AstValue.invoke(AstValue.java:161)
at com.sun.el.MethodExpressionImpl.invoke(MethodExpressionImpl.java:283)
at org.apache.myfaces.trinidad.component.UIXComponentBase.broadcastToMethodExpression(UIXComponentBase.java:1303)
Please let me know is there a way of adding the lib to the project.
Regards,
Suresh kumar.k

First you should check that the library has the checkbox 'Deploy by default' is checked for your library.
The you open the project properties of the view controller project, select Deployments, edit the deployment descriptor. Select the Node 'File Groups'->'WEB-INF/lib'->'Contributors'. this should give you a list of libraries your project uses. Check if your library has the checkbox checked (is selected fro deployment). If it's not checked, set it.
This should include the library.

Need help compiling external jar files into my one jar file from cmd line

Here is my problem, let me see if I can explain it right:
I am making a jar file on my development computer that will run my java project. In this java project, it references a couple Java3D jar files. On my development computer, I create the jar file and it runs correctly, but when I move that jar file over to the test computer, the parts of the application needing those Java3D jars are not found in my jar I created. I isolated the problem and it is because those Java3D jar files I needed are not on my test machine. But that is the way I need it to be. I need it so that when I compile all my code on the development machine, I need it to also compile those two Java3D files into my one jar that I move to the test machine. You get what I'm saying? I must do all the compiling from the command line and have only one jar file to put on the test machine that contains all my compiled code and the two Java3D files needed to run some of the applications in the project.
Here a brief sample of what I'm doing:
To compile my java files in my project, I simply to this for all my files:
javac file.java
javac file2.java... and so on for all my java files.
Then I create my jar file:
jar -cfm MyJar.jar manifest.mf file.class
jar -fmu MyJar.jar manifest.mf file2.class... and so on for all my class files.
Also when compiling my jar file, I do this thinking that it would include the two Java3D jars into my one jar file:
jar -fmu MyJar.jar manifest.mf jars/j3d-org-images.jar
jar -fmu MyJar.jar manifest.mf jars/j3d-org.jar
My manifest file looks something like this:
Manifest-Version: 1.0
Main-Class: Main
Class-Path: jars/j3d-org.jar jars/j3d-org-images.jar
Do I have to have that Class-Path in there pointing to those jar files? Those jar files will not exist on my test machine because the directory structure will not be the same. I've tried a manifest without specifying my Class-Path to those jar files, but I get the same problem when I run my application on the part that needs the Java3D files.
The error I am getting is that there is a RasterTextLabel class inside one of those Java3D jar files that my application cannot access because those jar files are not on my test machine.
So basically what I really need to know is how I get those two Java3D jar files compiled into my one jar file that I move to a test machine and run with the following command:
java -jar MyJar.jar
Can anyone help me??
Thanks.

Here what you need is to have all the files present in a single jar file, and the classpath is set properly to the required jar files.
Do the following in steps:
1)
Create a custom manifest file,say mymanifest.mf, with the following contenets, put it in current directory:
Manifest-Version: 1.0
Created-By: 1.4.0_01 (Sun Microsystems Inc.)
main-Class: Main
Class-Path: jars/j3d-org.jar jars/j3d-org-images.jar <press ENTER key>
2)
jar -cfm MyJar.jar manifest.mf file.class
jar -fmu MyJar.jar manifest.mf file2.class... and so on for all class files.
3)
jar -fmu MyJar.jar manifest.mf jars/j3d-org.jar
jar -fmu MyJar.jar manifest.mf jars/j3d-org-images.jar
(Make sure that j3d-org-images.jar and j3d-org.jar are present in a subdirectory called 'jars')
Now you would be able to run,
java -jar myjar.jar

How to use one external jar (SDK) for several apps in WTK?

Hi,
I have one external jar (SDK) I use for developing J2ME applications.
Every time I have no choice but to copy this JAR (SDK) into my current application lib directory.
I am building a family of MIDlets that I dont want to put into just one huge JAR but rather to have several JAR files for each application.
In C world I need only to tell the linker where it should pickup ".so" or ".lib" file.
Is any way to do the same with WTK? Or any other J2ME development tool?
Thanks in advance,
Andrew

Link to wtk2.5 beta has been posted to this forum
while ago. It's worth to try it It is MSA1.0
compliant. It has many new JSRs.TomTom,
Thanks again.
I tested the WTK2.5BETA and here I ahve strange fact. My application works perfectly on WTK2.1, WTK2.2 WTK2.3 BETA but it crashes with a very weird message on WTK2.5BETA
Method............: 22482ac 'com/tinyline/app/SVGEventQueue.handleEvent (virtual)'
Stack Chunk.......: 2216e44
Frame Pointer.....: 2216e7c

ALERT: java/lang/NoSuchMethodError: No such method dispatchEvent.(Lorg/w3c/dom/events/Event;)Z.
So I thought, OK it was compiled under WTK2.1 may it was the reason of crash.
I took sources and compile them under WTK2.5 BETA. I came up with the same result - crash.

Getting error while calling external Jars in BPEL by using Java embedding activity in soa 12c

Hi,
I am trying to use an external Jars for the business logic implementation. Here I need to pass XML as input and
and I expect the "Password " field has to be return.
Following are the steps I have followed:
1) Created a java project with sample class and added the external jars into the project "Libraries &Classpath".
2) Created a jar file out of it.
3) Created a BPEL project with Java Embedding.
4)Wrote the java code in java embedding activity.
4) Added the above created jar file to the BPEL project's lib/jar and added in SCA-INF/lib project folder as well.
5) Imported the package with the class as in the jar (e.g <bpelx:exec
import="pkg.testInterface"/>)
6) Deploy the BPEL project.
while deploying the SOA build is sucessful but my depoyment is incomplete.
error:
advices will be great....
Regards,
Dilip

Hi,
Can you confirm if the BPEL Version is 1.1 or 2.0.
If you are using BPEL 2.0 you need to import the required jar/class file as:
<import importtype="http://schemas.oracle.com/bpel/extension/java" location="pkg.testInterface"/>
For BPEL 1.1 the syntax to import other jar/class file is:
<bpelx:exec import="pkg.testInterface"/>
If you import the classes in the correct format you will not face any deployment error.

Including External JARs for Java Application in OC4J

Hi Experts,
Here is my requirement.
I have developed my Java application using Tomcat Server & Eclipse. In my application I have used some External JARs & imported the classes in my JSP.
Now that I'm using OC4J Server instead of Tomcat I'v no clue as to where I have copy these External JARs for my application to work.
I have installed OBIEE-Client which includes OC4J server. The path where I have placed my application is as below
*"C:\OracleBI\oc4j_bi\j2ee\home\default-web-app"*
If I run my application the server does not import the classes in the JSP which we include using Import statement using JSP tags (*ex* - <%@ page import = "org.apache.commons.fileupload.*"%>).
This is the location which I found, where I need to put my Java-J2EE application. This OC4J_BI comes with OBIEE.
Kindly help me out on where to place these External JARs exact location in OC4J.
Also let me know if I have to alter any configuration/xml file (if so pls specify the file name & its location).
Thanks in advance,
Venky

You can either include the external libraries in the application, by placing them into WEB-INF/lib, or you can import them into the server as "shared libraries", normally you'd use the "enterprise manager" application to do this. Having loaded a shared library you then add it to the classpath when you're deploying the application.

How to call external jar files in EJB project for CE

Hi,
I would be thankful if someone could help me with this -
I need to call the external jar files into my EJB project - Here is what I have done and am getting runtime exception as -
java.lang.RuntimeException: java.lang.NoClassDefFoundError: com/glance/pdf/pt/PTDoc
1. Created a EJB project" HelloWorld " using Java perspective in NWDS 7.1 called with client as HelloWorldClient and EAR project as HelloWorldEAR.
2. Am working on HelloWorld project (1st one).
3. In my code I am instantiating a class which is a class in one of the external jar file that I need to refer in my project.
4. I have set the Java Build path but it works only for the compile time and fails during runtime.
5. Have read I need to create external library DC and refer in my project "HelloWorld".
Can anyone help me with exact steps what needs to be done - during creation of external library project and then for my "HelloWorld" EJB project. How would I be able to reference or set the external library project in my EJB project?
Looking forward to hear from experts.
Thanks,

Hi Edson,
I tried it , but it still gives me runtime exception.
javax.ejb.EJBException: nested exception is: java.lang.RuntimeException: java.lang.NoClassDefFoundError: com/glance/pdf/pt/PTDoc
java.lang.RuntimeException: java.lang.NoClassDefFoundError: com/glance/pdf/pt/PTDoc
Steps I performed are -
1. Created a library project and created 2 Public parts "Compilation" and "Assembly"
2. Build the library project.
Now in my EJB project using Project Explorer - set the classpath and added both compilation jar and assembly jar files.
This is how the classpath entries for external library looks like -
<classpathentry kind="lib" path="/LocalDevelopmentLocalDevelopmentexternallibrarypdftoolsforwatermarkingdemo.sap.com/gen/default/public/WatermarkAssembly/lib/java/demo.sap.comexternallibrarypdftoolsforwatermarking~WatermarkAssembly.jar"/>
<classpathentry kind="lib" path="/LocalDevelopmentLocalDevelopmentexternallibrarypdftoolsforwatermarkingdemo.sap.com/gen/default/public/WatermarkCompilation/lib/java/demo.sap.comexternallibrarypdftoolsforwatermarking~WatermarkCompilation.jar"/>
I have also added the jar files I used in my external library project as "User Library" from Java Build Path . I dont do it , then the code fails during compilation itself.

I have got a swing application.
I need include tablelayout.jar in the class path.
How can I do this using .jnlp file?
Right now I can see the class not found exception in the console. I included the jar in /devlib folder under ROOT of Tomcat6.
When I started the application it is showing un registered entry message for devlib/tablelayout.jar
Please suggest how include the tablelayout.jar in the class path using .jnlp file
what is the reason for registration exception. Do we need to perform registry for each and every extenal jars we need to include?
Please help...

External Jars in program

Hello,
Sorry I know it's not an eclipse forum, but I couldn't get answers anywhere, so I hope someone here can help.
I have browsed the net a lot, and found that a lot of people are having similar issues, however I did not manage to make this work .
I have an rcp application which is just a GUI for using my application.
I also have another eclipse java project which has the core classes.
I want people to be able to use either the GUI or directly the JAR file created out of the second project.
Now the troubles :
the second project uses external jars, which I do NOT want to be packaged. I want the users to get those jar separatly and place them in the appropriate folder.
The first one (GUI) uses the second project (well it uses its jar file).
Inside eclipse I can make it work fine, problems come whenever I want to export either the GUI or the JAR from the second project.
What I would like to achieve is the following :
1) If they want to use the GUI, then there is a lib folder in its tree where they have to place all the external jars (and maybe the second project jar too, well I guess)
2) If they want to import the second projet jar in their own application, they have to get the external jars too and place them .... (somewhere? same directory I believe)
Now I have tried everything I found on the net without success : Add External Jars, add Jar, runtime tab, build-path, class-path, Project dependency, manifest etc ... in second or both projects.
I know the solution is somehow in those, but I just can't get it to work. Usually I get export errors on the RCP, sometimes its during execution.
If anyone could explain me step by step what I should do to achieve what I need, I would greatly appreciate it because it's kind of driving me mad.

Don't worry about how many JAR files you end up using. Don't go out of
your way to add JARs unless you know you need them. Typically, you write
code based on what you learn from research and add the JARs you need.
Usually, you won't acquire a lot of unnecessary JARs, but even if you
do, it doesn't hurt (except for a bit of diskspace).
Later, you'll discover which JARs you did or didn't need.
In short, don't worry about this. Just move ahead. You're on the right
track since you chose Java in the first place.

DownloadService.loadResource for external jars for 1.6.0-19+

First, be kind with my english, i'm french (nobody's perfect...)
I have a JNLP into which i declare a signed jar resource main.jar. This application retreive at execution a list of signed jar names (+a.jar, b.jar+...) that i dynamically load on my need through DownloadService.loadResource. My a.jar, b.jar are cached and it rules! But if i made a new main.jar, a.jar and b.jar, and deploy them on my server, here what's happend:
- main.jar is tested for modification date on server (thanks to "If-Modified-Since" HTTP header), cache date is before this date, so JWS update main.jar by downloading this new main.jar. This is the behaviour described into specs and it is perfect for me!
- but for others resources (a.jar, b.jar) i was excpected the same behaviour but JWS does not seems to check for modification date. So a.jar and b.jar are not updated.
So my first question: Is there a way to tell to DownloadService.loadResource to check for modification date? i could deal with jar version but this basic date checking was great for me...
Except this cache minor problem, external jar download works just fine except i get the warning security problem [Mixing Signed and Unsigned Code |http://java.sun.com/javase/6/docs/technotes/guides/jweb/mixed_code.html].
All my jars are signed with the same certificate, so i was a bit confused.
Anyway, i follow indications and put the Trusted-Only: true attribut into the manifest of main.jar.
But it leads to this exception:
java.lang.SecurityException: Trusted-Only loader attempted to load sandboxed resource from http://monserveur/a.jar
     at com.sun.deploy.security.CPCallbackHandler$ParentCallback.check(Unknown Source)

     at my.package.a$5.run(a.java:348)
     at java.lang.Thread.run(Unknown Source)I found some posts that deal with similar problems but it does not give me a working solution. The difference seems to be the fact that i load external jars (not defined into JNLP).
My JNLP is validated though JaNeLA.
I cannot set a.jar, b.jar as resources into jnlp because i retreive their location during execution...
My JNLP also declare:
<security>
        <all-permissions/>
</security>I think i'm a bit confused with the sandbox notion and the Trusted-Only: true attribut of the manifest. I also tried to add it to a.jar, b.jar and not main.jar but vainly. I also tried to set it on all jars but it does not work better.
Is there a way to load external jar without having the Mixing Signed and Unsigned Code warning popup? What do i not well understand?
Sorry to be so chatty...
Thanks in advanced for any answer.

So, I finally succed in finding a solution.
But this solution seems perhaps a barbarian way to solve my problem but it works.
The idea (as far as i understand) is that when you define "all-permission" into JNLP file, then these permission are granted for JNLP ClassLoader. When you load external jar through DownloadService.loadResource, then another classloader is used. It seems that this classloader does not inherit security policy from JNLP ClassLoader.
My solution is to define my own policy:
Policy.setPolicy(getAllPermissionPolicy());
    * @return a {@link Policy} with all permission granted
   private Policy getAllPermissionPolicy()
      Policy policy = new Policy() {
         private PermissionCollection m_permissionCollection;
         @Override
         public PermissionCollection getPermissions(CodeSource p_codesource)
            return getAllPermissionCollection();
         @Override
         public PermissionCollection getPermissions(ProtectionDomain p_domain)
            return getAllPermissionCollection();
          * @return an AllPermissionCollection
         private PermissionCollection getAllPermissionCollection()
            if (m_permissionCollection == null)
               m_permissionCollection = new AllPermission().newPermissionCollection();
               m_permissionCollection.add(new AllPermission());
            return m_permissionCollection;
      return policy;
   }For sure, you can decline this with permission you need. Here, all permission are allowed.
I'm not quite satisfied because it's seems to be a barbarian style solution. But for now, it fits my uses => no warning popup!
If anybody has a more proper way to deal with such an issue, i'll be glad to hear it!
Hope it helps.

How to use external jars in NW2004

Hello Experts,
can i use the same approach mentioned in the below Weblog for using the external jars in NW2004.
/people/bertram.ganz/blog/2008/11/24/how-to-use-external-jar-files-in-web-dynpro-development-components
and if not then what will be the best way to achieve it in NW2004.
Please provide your inputs on above.
Regards,
Siddharth

Hi Sidharth,
If you are using web dynpro DC perspective then you need to follow the following points to use the external jar files in it.
1. Create a external library project.
2. copy the external jars in the library folder os the projects.
3.) Select all the jars from the u201CLibrariesu201D folder, Right click and then select Development Component and click on Add to Public Part
4.Select the first Radio Button (Provides an API)and give some nameto it.
5. Repeat the step no 3 but now select the second radio button other than as selected in step no 4.
6. Now build your lirary DC.
7. Now create a j2ee DC project.
8. ) Expand the node DC Definition and Right Click on Used DC. Select Add Used DC.
9. Select the External Library DC with build time dependency.
10.Right click on the J2EE DC and then select Development Component followed by Build
11. Right click on the J2EE DC and then select Development Component followed by Deploy
now you can use both the libary DC and the j2ee DC in your web dynpro DC as used DC.
But if you have created a web dynpro project only(but not DC) than you can directly add the external jars in java build path
hope this will help
regards
Narendra
