Using shared objects (.so) with Java on Linux based Cloud

Hi all,

I am new to Linux and need help on the following matter, hopefully Linux experts out there can help me!

I want to create a Java Servlet that will interface with a shared object (.so) library. The library is a component provided by a SDK manufacturer.

This Java Servlet will be hosted on Apache Tomcat running in the Amazon Web Service (AWS) Cloud.

Is all these possible?

And could you point me in the right direction?

Thanks!

Yes, it's possible.

No, it probably won't be easy.

If you MUST interface 'C' code (i.e. code in a 3rd party .so) with Java, then your first stop should be to familiarize yourself with JNI.

I would create some standalone Java/JNI test programs that invoke the .so first, before I try to integrate them into the servlet.

'Hope that helps .. PSM

Hi paulsm4,

Thanks for your suggestions!

I was thinking the same approach on writing a JNI wrapper for my library and yes it won't be easy..
But I would give that a try, at least now i know it is possible!

Another way i was thinking was to create a Linux command-line executable in C++ to my library and run this executable from Java itself. The executable would take several parameters and perform its processes and return the results. Do you think this is a good idea?
