When enabling debugging I get the following output:

TCLBLEND_DEBUG: JNI_CreateJavaVM
TCLBLEND_DEBUG: JavaInitEnv returning successfully
TCLBLEND_DEBUG: initializing jcache
TCLBLEND_DEBUG: JavaSetupJava returning successfully
TCLBLEND_DEBUG: Now to create Interp object
TCLBLEND_DEBUG: Checking Tcl_GetNameOfExecutable()
TCLBLEND_DEBUG: Executable name is already known
TCLBLEND_DEBUG: called JavaInitBlend
Exception in thread "main" java.lang.NullPointerException: Invalid 
interpreter.
        at tcl.lang.Interp.getCommand(Native Method)
        at tcl.lang.BlendExtension.init(BlendExtension.java:37)
TCLBLEND_DEBUG: Exception in init() method
TCLBLEND_DEBUG: JavaInitBlend returning
TCLBLEND_DEBUG: Tclblend_Init finished
TCLBLEND_DEBUG: JavaInitBlend returned TCL_ERROR
"package require java" failed with the following error
"XpUtils::iload -d /usr/local/lib/tcljava1.3.2 tclblend" failed:
 java.lang.NullPointerException: Invalid interpreter.
TCLBLEND_DEBUG: called FreeJavaCache
TCLBLEND_DEBUG: called DestroyJVM



The error is from the file javaCmd.c:

somewhere in 

     /*
     * Associate the interpreter data with the interp object.
     */

    Tcl_SetAssocData(interp, "java", JavaInterpDeleted,
      (ClientData)interpObj);

    /*
     * Initialize the BlendExtension.
     */

    blend = (*env)-> NewObject(env, jcache->BlendExtension, jcache->blendC);
    (*env)-> CallVoidMethod(env, blend, jcache->init, interpObj);
    if (exception = (*env)-> ExceptionOccurred(env)) {
      (*env)-> ExceptionDescribe(env);
      (*env)-> ExceptionClear(env);
      obj = Tcl_GetObjResult(interp);
      ToString(env, obj, exception);
      (*env)-> DeleteLocalRef(env, exception);

something goes wrong. Unfortunatly I do not understand the code well enough to 
further investigate. Has anyone a clue for me?

Thanks,

wiwo
