Re: [api-dev] Java and com.sun.star.beans.XIntrospection.inspect() ?

Hi,

w.r.t. my problem description with the subject "Runtime problems when using Introspection&Reflection via Java" I also get a runtime error with your program.

F:\work\tmp\ooo\test>java Introspect
Exception in thread "main" java.lang.NullPointerException
        at Introspect.main(Introspect.java:28)
Line # 28 is highlighted as red and bold in your original code below:

The following Java program works just fine for me:

import com.sun.star.beans.PropertyValue;
import com.sun.star.beans.XIntrospection;
import com.sun.star.beans.XIntrospectionAccess;
import com.sun.star.beans.XPropertySet;
import com.sun.star.bridge.UnoUrlResolver;
import com.sun.star.comp.helper.Bootstrap;
import com.sun.star.frame.FrameSearchFlag;
import com.sun.star.frame.XComponentLoader;
import com.sun.star.lang.XMultiComponentFactory;
import com.sun.star.uno.UnoRuntime;
import com.sun.star.uno.XComponentContext;
public final class Introspect {
    public static void main(String[] arguments) throws Exception {
        XMultiComponentFactory factory = (XMultiComponentFactory)
            UnoRuntime.queryInterface(
                XMultiComponentFactory.class,
                (UnoUrlResolver.create(
                    Bootstrap.createInitialComponentContext(null)).
                 resolve(
                     "uno:socket,host=127.0.0.1,port=12345;urp;"
                     + "StarOffice.ServiceManager")));
        XComponentContext context = (XComponentContext)
            UnoRuntime.queryInterface(
                XComponentContext.class,
                (((XPropertySet) UnoRuntime.queryInterface(
                      XPropertySet.class, factory)).
                 getPropertyValue("DefaultContext")));
        XIntrospectionAccess access =
            ((XIntrospection) UnoRuntime.queryInterface(
                XIntrospection.class,
                factory.createInstanceWithContext(
                    "com.sun.star.beans.Introspection", context))).
            inspect(
                (((XComponentLoader) UnoRuntime.queryInterface(
                      XComponentLoader.class,
                      factory.createInstanceWithContext(
                          "com.sun.star.frame.Desktop", context))).
                 loadComponentFromURL(
                     "private:factory/scalc", "_blank",
                     FrameSearchFlag.CREATE, new PropertyValue[0])));
        System.exit(0);
    }
    private Introspect() {}
}
So it is affected as well (does not work anymore).

In the meantime I have de-installed all OpenOffices (1.1.4, 1.9), deleted all remainders of these installations in the file-system, tried to find traces in the Windows registry and deleted them.

Then - after reboots - I re-installed OOo 1.9 only, but to no avail.

Are there any registry-entries which might affect this behaviour that have keys other than "OpenOffice" or "soffice" ? Or could it be, that some cache is being used that contains erroneous data?

Regards,

---rony
