I try to load two MBeans via the javax.management.loading.MLet class and the
getMBeansFromURL method.
I keep getting an StackOverflowError, I guess caused by some class loading
problem.
This works on Sun AS 8.1 and on WebLogic 9.0...
Here is the mlet tags:
<MLET
CODE=com.j2ee.jmx.J2ee.class
ARCHIVE=j2ee-jmx.jar
CODEBASE=/
NAME=MLetTest:name=J2ee
>
<MLET
CODE=com.j2ee.jmx.J2eeJmxNotificationListener.class
ARCHIVE=j2ee-jmx.jar
CODEBASE=/
NAME=MLetTest:name=J2eeJmxNotificationListener
>
Some code:
String domain = mBeanServer.getDefaultDomain();
String mletClass = "javax.management.loading.MLet";
ObjectName mletName = new ObjectName(domain + ":name=" + mletClass);
if(!mBeanServer.isRegistered(mletName))
{
mBeanServer.createMBean(mletClass, mletName);
}
Object mletParams[] = {"http://localhost:8088/mlets.html"};
String mletSignature[] = {"java.lang.String"};
Set mbeanSet = (Set) mBeanServer.invoke(mletName, "getMBeansFromURL",
mletParams, mletSignature);
I get the following error:

.... This loops until the stack is overflowed.
Any ideas??
