[vtkusers] Problems in VTK Java & Linux

[Dhanesh Ramachandram, PhD]

We're trying to port an Eclipse RCP application which uses VTK and ITK
wrapped as plug-ins from Windows to Linux (Ubuntu 9.04). We've
completed the initial steps of building the Linux shared libraries of
VTK and ITK with Java Wrapping enabled. When our application tries to
access VTK libraries, it seems that there is a problem. We have set
the appropriate LD_LIBRARY_PATH etc...
What can be the issue here ?  It seems that in Linux, the shared
libraries have the prefix 'lib' (ex: "libvtkCommonJava.so") but
somehow, from the error messages, it seems that the wrapping procedure
results in code that tries to access the library "vtkCommonJava".
Could this be the problem ?

Here's the error we get:
