Multiple Version of same Jar

Dear All,

I have the task of file copy. So I have downloaded the apache commons-net (3.1) from the net. I have developed the Module using the 3.1 commons-net.

But fs-webrt.jar has commons-net jar (may be 2.1). After deploying the module to the server, My module code invokes FTPClient from  fs-webrt.jar's commons-net not from the Module (commons-net 3.1). Many methods are missing in the commons-net 2.1 version.

Is there any way resolve the jar version ?? or Is there any way to tell the classloader to load the Modules commons-net jar ??

Thank You,

If you don't need any dependency from the fs-webrt.jar, you can simple remove it from the generated .war file before you deploy it to your servlet container.

Hi Christoph,

do you have an overview of all the libs and the used version from the fs-webrt.jar (FS-Server Version 5.1.416, and newest And why is the fs-webrt.jar generated into the .war file, when it isn't needed?

Thank you,
