Re: [sdljava-users] Re: Problems with SDLJava_Image.dll and jpeg.dll

[Patric <pa...@ma...>]

Hi Ivan,

Yes, I am using Eclipse. Yesterday I tried everything to get it working 
before I had the idea patching the dlls: I played around with 
bootclasspath and java.library.path. But I didn't get it working. It 
seems that an vm instanced by Eclipse favours the JRE/bin path - 
independent of the passed vm arguments.

At command line everything worked perfect (with the same vm arguments, 
working directory and jre as in eclipse!

In my Eclipse environment I tried passing "sdljava.bootclasspath" to the 
vm (with the unpatched libraries), but it didn't have any effect, the 
ordinal 50 problem always occured.

Yes, my fix works fine at the command line.

Best regards,
Patric
