Yes, that's right. We are currently working on implementing persistent 
storage for jTSS.

Ok, if you can compile it you should have all required libraries etc. on 
your system.
Of course, you need to have the TPM driver and TrouSerS up and running 
before you try any access!

The best way to start is to try
  makefile run_tests
with the newly built Wrapper. At this target in the makefile you can see 
  which environment is needed to use the classes.
Once this runs from the shell, you should configure your IDE.

You will have to add the two created jars (as external jars) to your 
project to compile.

iaik_jtss_wrapper.jar
iaik_jtss_wrapper_swig.jar

adding JUnit 3 might be useful, but is no requirement.

To run your application, you need to add these jars to your classpath. 
Furthermore you have to extend the LD_LIBRARY_PATH environment variable
path, to include outpub/lib with the

libtspiwrapper.so

In Eclipse you can do this by selecting the class that contains your 
main(), and then Run as..


 > I have to make any alterations to my java code?
Yes.

You have to use class
  TcTssJniFactory (for wrapper)
instead of
  TcTssLocalCallFactory (for jTSS)
to instantiate your first factory.
