Does the native library consist of a single .so file, or there are several ones?
See the second "NOTE MEG" here: http://wrapper.tanukisoftware.org/doc/english/prop-java-library-path-n.html It is about requirements for LD_LIBRARY_PATH if there are several libraries. Does your printenv mention the value of LD_LIBRARY_PATH? Is there any difference compared to when you are running Eclipse? 2007/10/17, David Marshall <[EMAIL PROTECTED]>: > The results of printing System.getProperty("java.library.path") in the > jsp does show the correct path to my shared object.... > > > > Looking forward to your results with JSP. > > > > > > 2007/10/17, David Marshall <[EMAIL PROTECTED]>: > > > >> I'm not doing a System.loadLibrary.
