[vtk-developers] vtkGenerateJavaDependencies

[Andy Cedilnik]

Hi John,

I think all that stuff should be removed and generated using
VTK_WRAP_JAVA2. The only thing you should do manually is to create jar
file and tests. I have this in my long term plan, but since it is not
high on the list, it may take a while.

Being completely new to Java and wanting to build a set of Java wrappers (+jar archive) for some custom vtk classes I found that it only worked if I actually generated all the java stuff inside the vtk build tree. I found this troublesome because I wanted

The only way I could get it to fully link (in Java afterwards) was by adding a USER_JAVA_CLASSPATH variable to my cmakelists and adding a check for this to vtkGenerateJavaDependencies so that the classpath was inserted (in this case, pointing from my build tree back to the vtk java build tree).
