How to create a Jar with only class files?

Dear all,
I want to create a jar file with only classes.My class files and java files are in different folders under com .
say
com
in com there are two folders
folder 1 -- subfolder 1
folder 2 -- subfolder 2
like this.
If i want to create a jar file from com directory how should i give the jar command.Again my jar should contain only .class files.
Any help will be appreciated
Thanks
lekshmi

It doesn't work.Says "No such class or directory"
Any other way Or is it possible to do so?Read the link I posted and create the statement to make your structure. I was thinking you were inside the com directory but if you are above it you will need something like this instead:
jar -cf test.jar com\*.class com\subfolder1\*.class com\subfoler2\*.class
But either way don't just copy and past this. Think about what is does so that you can make it work for you.
Also, you might want to look into using Ant if you are going to be building this a lot.

can u help me to achieve this requirement.???
im stuck with this,,,if u can provide me wit the code for updating jar file with latest class file...it will really be helpful
if u can help me with the code on click on update button it will be really helpful
Thanks and expecting a faster response from u all java experts....

Which jar has ConnectionProperties class file?

Hi,
I am trying to connect to the SAP system. I am unable to find the ConnectionProperties class file. It is not there in com.sap.portal.ivs.connectorservice_api jar file.
Please let me know where this class file is and send me the appropriate jar file.
I tried going to libraries.zip, but it is not there either.

Hi Akhilesh,
There is no such jar file in the installation. I have com.sap.portal.ivs.connectorservice_api.jar. There is a underscore before api. This jar does not have the ConnectionProperties class.
If you have this jar, please mail me. My ID is [email protected]
Thanks in advance,

Assembling jar with dependent classes

For efficient Applet use I'd like to copy selectively into a jar my applet classes plus all classes they are dependent on from a set of libraries, thus producing the minimum jar library with which the applets can run (obviously classes which are part of the standard JRE are not to be included.
Now I can see, in outline, how to write a program to achieve this, but I have this feeling I've read about such a facility somewhere. I thought it was in ANT but I can't find it in the ANT documentation now. If someone knows of a utility (preferably free) that can do this please can you save me the trouble.

Well, I think I've found one on sourceforge: http://genjar.sourceforge.net/
I've also found out how to get dependant classes from a .class file relatively simply. Class references are listed in the Constants Table which is near the start of the .class file format. I've written a piece of code which seems to fetch them OK.

Loading jars with same class loader

Hi all,
I need to tell Weblogic to load various jars using same class loader.
"various jars" means jars that belong to different web applications. (weblogic 10)
Is that possible ?
PS: I can not change jar location, e.g. put them in common directory or so.

Hi,
If you don't want to change the JAR Locations then you can try the following..
Option1). Add the Jar Location with the Jar file name in the Server classpath...of your server startScript (like startWebLogic.sh)
CLASSPATH=${CLASSPATH}:/opt/app/myJars/first.jar:/opt/app/myJars/second.jar:
But in this case the Jars which are there in the classpath...will be loaded using System Classloaders and will be different from Application Classloaders...but the Classes belonging to these Jars will be available to your applications because final classpath will be the Summation of following:
Final Classpath = Bootstrap classloader (+) System ClassLoader (including Extended Classpath from Domain Lib) (+) Application ClassLoader (+) AppModule ClassLoader
Option2). If you dont want to add the Jars in the Server ClassPath then u can use "Optional Package" deployment feature provided by WebLogic...In this case you can deploy the JARs in WebLogic Server as Optional Packages from the Same Location where it is at present...(as you dont want to change the Jar locations) like following: http://jaysensharma.wordpress.com/2009/12/06/optional-packages/

How to compile and register a Java CFX tag with multiple class files?

All-
If this is the wrong forum for CFX questions, please let me
know.
I need to determine how to compile and register a Java CFX
tag that contains multiple class files. One class file implements
the CustomTag interface and the other class files implement various
supporting classes. All of the documentation that I have found
talks about using a single class file. I am assuming that a JAR
file will be involved, but I am not sure of the specifics.
Thanks in advance for your help.
-Josh

Yes, it will involve a jar. Use your java IDE (eclipse,
etcetera ..) to create a jar containing all of the classes. Check
your ide's documentation for how to create jar files. After you
have created the jar, place the jar in the CF class path so CF will
recognize it. For example the {cf_root}/WEB-INF/lib directory. CF
must be restarted before it will detect the new jar. After
restarting CF, register the CFX tag in the ColdFusion Administrator
using the name of the class that implements the CustomTag
interface.
Though it is worth noting you can also instantiate java
classes directly from ColdFusion (ie without using a CFX
tag).

VM crashes with big class files generated of JSPs

 Hi,
 When calling certain JSP pages with WebLogic Server 5.1 (SP 6) the HotSpot Virtual Machine (JDK1.3) crashes with a core dump.
 Using WebLogic as the JSP engine produces of every JSP page one java file which
 is compiled with javac to one class file. Each generated java file consists of
 just one method: _jspService(...){...}. One method is allowed to be of 64 K
 (the dynamic part 32 K as maximum). As we include other JSP pages and
 components and use taglibraries, the WebLogic JSP engine generates a very big
 java file (more than 1 MB). Javac compiles this to a class file which only
 method exceeds the 64 K limit. As the javac compiler does not reject the class
 file with the to big method the virtual machine crashes.
 Running the same JSP page on Windows NT 4 with WebLogic Server 5.1 (Service Pack 6)
 and JDK 1.3 BUT using the java option -classic works.
 Unfortunately it seems that there is no -classic option for java on Solaris for JDK1.3.
 Using JDK1.2 (JDK_1.2.2_05a) on Solaris or the jikes compiler of Jakarta
 causes an exception instead of a core dump but still does not work.
 Using solaris jdk1.2.2_05a the same page request results in the following exception:
 Tue Nov 21 09:08:16 CET 2000: <WebAppServletContext-maxblue> Generated java file:
 /opt/tadevw/maxblue/weblogic/maxblue_cluster/maxblue_server/public_html/WEB-INF/_tmp_war/jsp_servlet/_portfolio/_PortfolioMyportfolio.java
 Tue Nov 21 09:08:24 CET 2000:<E> <WebAppServletContext-maxblue> Servlet failed with Exception
 java.lang.VerifyError: (class: jsp_servlet/_portfolio/_PortfolioMyportfolio, method:
 _jspService signature: (Ljavax/servlet/http/HttpServletRequest;Ljavax/servlet/http/HttpServletResponse;)V) Illegal target of jump or branch
 Is there a way that the JSP engine of WebLogic creates/generates
 more than one function? (Without reengineering of the source code?)
 Regards,
 Boris


Thank you! I had no idea. But what is a FAT32 drive? Is it the work bench in the Mac, that is used for the transfering between the external hard drives? Is there any way around this then?
I thought in these HD home movie days, that this was an easy thing dealt with everyday. I still need to understand what practical solutions I can find. The files are .mov - quicktime files.
It couldn't be the case that files larger than 4BG should be locked in the hard drive forever?

Need help with a class file!

How do you decompress or decompile a class file??? I just can't seem to get it...

One program is called JAD...
Also the jedit program has a plugin to decompile class files.

2 Jars with same class name. NoSuchMethod. Can't change classpath

I have overloaded a method in a class that came with an openSource package.
Things were fine until I implemented my components in a new version of the Server application; when I discovered that the it uses the same openSource package bundled in its classpath.
This results into a NoSuchMethod exception since I have overloaded the method with new argument types.
1. I cannot remove or shuffle this JAR from the Server's classpath, since that would stop something else.
2. I cannot change my code since it is implemented in a lot of places.
Has anyone called a specific method of a jar? like E.g. "someJar.jar".SomeClass.someMethod (arg);
If yes how?
The above code is not possible syntactically, but I have put it for ease in interpreting the problem.
Any input will be appreciated.
NOTE: I cannot disclose the names of products for company policy issues.

Just some ideas...
1. I cannot remove or shuffle this JAR from the
Server's classpath, since that would stop something
else.Some servers allow for multiple classpaths - i.e. you can separately specify the classpath that the server itself uses from the one that your hosted applications will be using.
Also, if your changes to the openSource code are only the addition of an overloaded method, why couldn't you just substitute your jar for the one the server is using, why would that break the server?
2. I cannot change my code since it is implemented in
a lot of places.That sounds lame. You can't do a global replace? How about just changing the package name?
Has anyone called a specific method of a jar? like
E.g. "someJar.jar".SomeClass.someMethod (arg);
If yes how?Yes, but it's not as simple as your pseudo-code...
You can use URLClassLoader to load a specific class from a specific jar file URL, and then use reflection to get the method you want from it, and then call it.
good luck

Creating a JAR with main class def.

Hello Amigos,
I am having problems creating a jar file. My problem is that when I create the jar file and insert this line in my manifest file
Main-Class: classnamewhere classname is what ever class you want as explain here:
http://java.sun.com/developer/Books/javaprogramming/JAR/basics/run.html
Then I have the jar file and double click it and get the Fail to load Main-Class error.
This is what I am typing in the command line:
jar cmf MANIFEST.MF myapp.jar *.class
When I go back and extract all the files out of the jar file the manifest files looks like this:
Manifest-Version: 1.0
Created-By: 1.3.1 (IBM Corporation)Thanks in advance

No ofense but... You got to be kidding me!?!?!Not kidding at all. Had you read the online tutorial, you'd have found the following line:
Warning: The text file must end with a new line or carriage return. The last line will not be parsed properly if it does not end with a new line or carriage return.
Have you tried it yet?

Some codes related with connection and file upload

This is for the connection to the smart card code. If there is sth wrong please inform this. And I do nt know why there is no pin verification while connecting to card....
// show the list of available terminals
TerminalFactory factory = TerminalFactory.getDefault();
List<CardTerminal> terminals = factory.terminals().list();
System.out.println("Terminals: " + terminals);
// get the first terminal
CardTerminal terminal = terminals.get(0);
// establish a connection with the card
Card card = terminal.connect("T=0");
System.out.println("card: " + card);
CardChannel channel = card.getBasicChannel();
ResponseAPDU r = channel.transmit(new CommandAPDU(c1));
System.out.println("response: " + toString(r.getBytes()));
// Here do your processes
// disconnect
card.disconnect(false);
This is code of storing a file whose extension is p12 to the smart card. Is this for storing a existing certificate(C:file.p12 as an example) to smart card?
CertificateFactory cf = CertificateFactory.getInstance("X.509");
X509Certificate cert = (X509Certificate)
cf.generateCertificate(new java.io.FileInputStream(certFile));
dest.setKeyEntry(alias, key, kstorePassword, chain);
dest.setCertificateEntry("cacert", cert);
dest.store(new java.io.FileOutputStream(keystoreFile), storePassword);
Thanks for your responses ....
Best Regards,
ilkay POLAT

Authenticating with a PIN will depend on the applet on the card you are trying to authenticate to. If the applet is ISO7816, you should have a look at the ISO7816-4 specifications for the APDU command for VERIFY (used to verify user password or PIN).
I guess it comes down to the applet. You may have to check the standard is was developed for (ISO7816, EMV, etc) for the APDU required to verify a users PIN.
If you are having problems connecting (or are unsure what protocol to use) you can use the following line to connect. This will attempt to connect with any available protocol.
Card card = terminal.connect("*");I hope this helps.

Jars and .class files - security of the source code

Hi,
I have an app that is in a jar file with the .class files (so no source code).
I'm wondering how difficult it is to attain the source code from these .class files in my jar? Looking through the contents of the .class files it seems there is a large amount of readable text. For example I see method names, variables, etc.
This leads me to believe these jars are not secure. What is a better way?
Thanks!
Edit:
Looking around, I've noticed many java decompilers and Sun even supports a dissembler - javap. I think this is not cool, haha.
What way can I protect my code? To me, the value of java just went way down due to the ease at attaining source code (based on what I read in the past hour or so. I have yet to try it myself). I wonder if this impacts companies reasons not to use java?
Edit 2:
I heard that there may be a way to make the jar closed, so you can't say, use winrar, to extract the class files. Does anyone know anything about this?

You can use tools called obfuscators to make decompiling more difficult, which is usually good enough. The truth is, no matter how great you think your code is, it's of a lot less interest to others than you actually think. Unless you've got a particularly sexy argorithm or something, it's not really worth worrying too much about
All you can do is make it more difficult for people to crack things, never prevent it. True of all languages, all electronic media

Run app with Class Files from JBuilder

I have Java class files (at this point no java source code/files).
How can I run the application from JBuilder with these class files.

Thank you Annie.
I want to run JBuilder in debug mode.
Basically my application connects to the Sybase db. It will get some data from tables. But when I am running my app in debug mode ... I am hoping that it will show me the data. I dont see any data from the db tables.
Do I need to setup anything else to see what data it is selecting through JBuilder

Classes12.jar with connection.class file
