How to add new jar file to existing deployed jar in server

Question

I have a RMI application which is running on the server. Now i want to add external jar file to an existing deployed jar.

Note: It is not web application.

For example, here i mention the jar directories

MyApplication.jar

manifest.mf
.classpath
classes
- My java class files
lib
- test.jar
- test1.jar
images
META-INF
- MANIFEST.MF

.classpath has

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
  <classpathentry kind="src" path="src"/>
  <classpathentry kind="lib" path="lib/test.jar"/>
  <classpathentry kind="lib" path="lib/test1.jar"/>
  <classpathentry kind="output" path="classes"/>
</classpath>

Now i want to add test2.jar to my lib folder inside MyApplication.jar and updating .classpath file.

Is it possible to add it?

i don't think this is possible to do without restarting. Make your replacements, modify the .classpath , and then runt the jar again. — Sampada, Jun 24 '16 at 11:07
@jens: Yes, a jar can not include jar files but using one-jar i can build single jar with libraries. — Tamil, Jul 06 '16 at 05:58

If you cannot use JRebel then you will probably have to try to write your own class loader to achieve this. There are many pitfalls. See this answer and this question for some pointers.
