The error message below means that you do not have vtkCommonJava.dll in 
you system path, at least the way you JVM sees the path. Add following 
at the beginning of you main() function :

System.out.println("java.library.path: " + 
System.getProperty("java.library.path"));

To verify that your system PATH variable is set correctly (it should 
have the directory containing vtk*.dll, including vtk*Java.dll). One 
thing that I noticed recently on some WinXP system is that dynamic 
libraries from paths containing spaces, for instance, C:\Program 
Files\vtk\bin, may not load correctly, even if you put them in quotation 
marks"". Best way to fix it is to move your dlls into a path without 
spaces, for instance c:\apps\vtk42. Other thing that may work is to 
convert you paths with spaces to "~' notation, for instance, 
c:\Progra~1\vtk42\bin (this may look slightly different depending on you 
system configuration).

Looks that you selected an incorrect class to run. A simple way to run a 
class in IDEA is to open the code in the editor and press 
Ctrl+Shift+F10, alternatively right click on the class name in the 
Project or Package pane and select "Run" (if a class does not have a 
proper main() method the "Run" option will not be available).

BTW: I do use IDEA 4 with my VTK projects, both on Linux and Windows. To 
setup an IDEA project you only need to location of the vtk.jar. Location 
of VTK DLLs and the jawt.dll can be easily handled by the system PATH 
variable (or LD_LIBRARY_PATH on Linux).
