JMX from within an iView

[Former Member]

Hi,

I've got problems using JMX from within an iView. I try to connect to the local MBeanServer using the following code:

[code]

public void doProcessBeforeOutput() throws PageException {

Form myForm = this.getForm();

...

// Get connection to MBeanServer

InitialContext ctx;

try {

ctx = new InitialContext();

Object objref = ctx.lookup("jmx");

MBeanServer conn = (MBeanServer)objref;

} catch (NamingException e) {

e.printStackTrace();

}

[/code]

The lookup returns an object of type "com.sap.pj.jmx.server.interceptor.MBeanServerInterceptorChain" which should implement

the Interface "MBeanServer". Anyhow I get the following error while trying to cast the returned object to type MBeanServer:

I set the "tc/jmx"-library as "Additional Library" using the Right-Mouse-Click-Context-Menu on the Project Node in Netweaver

Developer Studio...

What else needs to be done to get jmx working in an iView-Environment?

Thanks in advance

Hello Thorsten,

Did you specify sharing reference to jmx service? Check http://help.sap.com/saphelp_erp2004/helpdata/en/88/bdfc3f48ecc742e10000000a1550b0/frameset.htm

Thank you Maksim,

when specifying a sharing reference like

SAPJ2EE::library:tc/jmx

in the portalapp.xml-File, the server-lookup is working.

Best regards,

Thorsten
