i'm using eclipse noen and i've created a jar file contains only one java file. but when I added to the application library it still can't be seen.
Can you post the strutcture or an example of the contents of the JAR file?
JAR files should contain compiled java classes, not ".java" files.
If you are using Eclipse, create the JAR file by exporting the project.

Use jar xf <JAR-file> to extract the entire JAR file to whatever directory you're currently on.
Add your new code to the files, removing the old code (make sure you have copies or back everything up, just in case).
Use jar cvf <JAR-file-name> * to create a JAR using all contents in the directory of your files.

I have opened a jar file in a Winzip, there is a Java file that need some modification, modified it inside jar. Now the Java file's .class is needed. How can I generate class file from a Java File which is inside the Jar. Do let me know any command line available. I cannot unpack the jar as there are some class files inside that is not open source. Overall I want to add a line of code to java file and replace class file with update version of java file.
