Hi Daniel, * Or maybe rephrased: if reflecting an UNO object, does one need to use an instance of "com.sun.star.reflection.CoreReflection" from the same context as the reflected UNO object? No, you need not use the same component context, but it may be more performant to choose one within your process. Please use the singleton entry "com.sun.star.reflection.theCoreReflection" for the sole reason that it internally caches created IdlClass objects. When will that object be registered? Is there anything I could do that it gets registered and available at bootstrap time? What follows is a small Java program that shows that "theServiceManager" is registred with the context, but "theCoreReflection" object is not yet. ---------------- cut here -------------- import com.sun.star.comp.helper.Bootstrap; import com.sun.star.uno.UnoRuntime; import com.sun.star.uno.XComponentContext; public final class RgfUnoAnalyzeTest2 {     public static XComponentContext defaultContext=null;     /** Static block to initialize static fields. */     static {         try         {             XComponentContext ctxt0=Bootstrap.createInitialComponentContext(null) ;             System.err.println("ctxt0="+pp(ctxt0));             String key="/singletons/com.sun.star.reflection.theCoreReflection";             Object tcr2=ctxt0.getValueByName(key);             System.err.println(key+"\t=\t"+pp(tcr2));             key="/singletons/com.sun.star.lang.theServiceManager";             tcr2=ctxt0.getValueByName(key);             System.err.println(key+"\t=\t"+pp(tcr2)+"\n");         }         catch (Exception e)         {             System.err.println("Exception:" + pp(e) + "has occurred!");         }     }     public static void main(String[] arguments) throws Exception {         System.out.println("In main()...");         System.exit(0);     }     private RgfUnoAnalyzeTest2 () {}     public static String pp(Object o)     {         if (o==null) return "<null>  <=== <=== <===";         return "<"+o.toString()+">";     } } ---------------- cut here -------------- Output: ---------------- cut here -------------- F:\work\tmp\ooo\tst>java RgfUnoAnalyzeTest2 ctxt0=<[EMAIL PROTECTED]> /singletons/com.sun.star.reflection.theCoreReflection   =       <Any[Type[void], null]> /singletons/com.sun.star.lang.theServiceManager =       <[EMAIL PROTECTED]> In main()... ---------------- cut here -------------- Any hints, insights?
