[Insight-users] Java troubles

[Luis Ibanez]

Daniel,

Just for the record,

   The fix was made in the files

     Insight/Wrapping/CSwig/SwigRuntime/
                                  JavaCWD.h
                                  JavaCWD.cxx

http://www.itk.org/cgi-bin/viewcvs.cgi/Wrapping/CSwig/SwigRuntime/JavaCWD.cxx?r1=1.2&r2=1.3&root=Insight
http://www.itk.org/cgi-bin/viewcvs.cgi/Wrapping/CSwig/SwigRuntime/JavaCWD.h?r1=1.2&r2=1.3&root=Insight


Thanks for letting us know that the old JDK 1.4.1_02
will still not work. We just added a comment on this
to the README file in


    Insight/Wrapping/CSwig/README


Please let us know if you find any further problem,


    Thanks,


      Luis
