gcj exception compiling

[Kraus Philipp]

Hello,

I try to build a Java class with the gcj under Cygwin. I get this error message:

Exception in thread "main" java.lang.NoClassDefFoundError: org.eclipse.jdt.inter
nal.compiler.batch.GCCMain
   at gnu.java.lang.MainThread.run(Unknown Source)
Caused by: java.lang.ClassNotFoundException: org.eclipse.jdt.internal.compiler.b
atch.GCCMain not found in gnu.gcj.runtime.SystemClassLoader{urls=[], parent=gnu.
gcj.runtime.ExtensionClassLoader{urls=[], parent=null}}
   at java.net.URLClassLoader.findClass(Unknown Source)
   at java.lang.ClassLoader.loadClass(Unknown Source)
   at java.lang.ClassLoader.loadClass(Unknown Source)
   at gnu.java.lang.MainThread.run(Unknown Source)

The class does not have any main function. 
On the default gcj installation, it creates this error first:

/usr/lib/gcc/i686-pc-cygwin/4.5.3/ecj1.exe: error while loading shared libraries
: cyggcj-11.dll: cannot open shared object file: No such file or directory

So I install the gcj-11 library, the setup installs gcj-9 on default.

How can I create a working installation?

Thanks

Phil
