Hi,

I have MBean operations.
I am able to invoke getXXX operations without arguements.
But when I try to invoke operations (delete, update, and add) with arguement?
I am getting runtime error.

Do I need to do anything differently when I invoke those operations with arguement?
Can you help?

public List<Catalog> getAllCatalogs() {
try {

			MBeanServer server = ManagementFactory.getPlatformMBeanServer();
			ObjectName name = new ObjectName(
					"bean:name=CatalogMbean");

			String[] sig = {};
			Object[] arg = {};
			list = (List<Catalog>) server.invoke(name,
					"getAllCatalogs", arg, sig);

			Iterator<Catalog> it = list.iterator();
....
skipped rest

Open in new window


The above returns fine.

public void deleteCatalog(Catalog cat) {

      if (cat != null) {
                  try {

                        MBeanServer server = ManagementFactory.getPlatformMBeanServer();
                        ObjectName name = new ObjectName("bean:name=CatalogMbean");                        
                        
                        String[] sig = { int.class.getName() };
                        Object[] arg = {cat.getId()};
                        rowNo = (int) server.invoke(name,"deleteCataglo", arg, sig);

                  } catch (Exception e) {
But I try to delete using id, it gives me a runtype error

)javax.management.RuntimeOperationsException: RuntimeException occurred in RequiredModelMBean while trying to invoke operation deleteCatalog(Catalog cat)

Two things...

- I hope that the method name in your invoke call above, "deleteCataglo" is just a typo and you are using the real method name?

- Can you post the full stack trace that you get?

I see in the code above that you are catching all exceptions thrown. What are you doing with the exception? ie. what is directly after the code that you posted above?
