Subject Re: Error when starting Geronimo
Date Wed, 07 Apr 2004 15:48:46 GMT
Hi,

I had the same problem yesterday on winXP sp1 jdk1.4.2_03 latest_source_from_head


The problem is in the kernel module in

org.apache.geronimo.gbean.jmx.GBeanMBeanReference in line 283


proxy.removeTarget((ObjectName) notification.getSource());

proxy or notification is NULL in this moment, but I don't know why because....


I'm new to geronimo and I have to learn how to debug a running geronimo.

Anybody an idea or a quick howto about how to debug geronimo in Eclipse?


yo
