Strange behaviour of JndiTemplate

[asv]

Hello!

I have configured spring JMX with SAP WAS. SAP WAS requires to pass user auth information to InitialContext like:

properties.put(Context.SECURITY_PRINCIPAL, this.username);
properties.put(Context.SECURITY_CREDENTIALS, this.password);
new InitialContext(properties);

In order to lookup server I use JndiObjectFactoryBean and JndiTemplate.
The user's auth information is passed as environment property of JndiTemplate.

But I get

java.security.AccessControlException: access denied (javax.management.MBeanPermission javax.management.modelmbean.RequiredModelMBean#-[:

I have extends JndiTemplate

public class CustomJndiTemplate extends JndiTemplate {

    private static Log logger = LogFactory.getLog(CustomJndiTemplate.class);

    protected Context createInitialContext() throws NamingException {
        return super.createInitialContext();
    }

    public Object lookup(final String string) throws NamingException {
        Object objMBeanServer = createInitialContext().lookup(string);
        return  objMBeanServer;
    }
}

It works!

Then I change the code:

public class CustomJndiTemplate extends JndiTemplate {

    private static Log logger = LogFactory.getLog(CustomJndiTemplate.class);

    protected Context createInitialContext() throws NamingException {
        logger.debug("@@@@@@@ Environement=" + getEnvironment());
        return new InitialContext(getEnvironment());
    }


    public Object lookup(final String string) throws NamingException {
        logger.debug("@@@@@@@ Lookup=" + getEnvironment());
          return execute(new JndiCallback() {
			public Object doInContext(Context ctx) throws NamingException {
                logger.debug("@@@@@@@ Lookup2=" + ctx.getEnvironment());
                return ctx.lookup(string);
			}
		});
    }
}

It doesn't work! The same exception.

My Log content:

jmx.CustomJndiTemplate - @@@@@@@ Lookup={java.naming.security.principal=Administrator, java.naming.security.credentials=abcd1234}
jmx.CustomJndiTemplate - @@@@@@@ Environement={java.naming.security.principal=Administrator, java.naming.security.credentials=abcd1234}
jmx.CustomJndiTemplate$1 - @@@@@@@ Lookup2={java.naming.factory.initial=com.sap.engine.services.jndi.InitialContextFactoryImpl, java.naming.security.principal=Administrator, server=true, java.naming.security.credentials=abcd1234}
jndi.JndiLocatorSupport - Located object with JNDI name [jmx]

I suppose the problem is with inner class but I have no idea why it dosn't work.

Could you explain why it doesn't work?

your line of code new InitialContext() has to use the constructor with appropriate properties INCLUDING a context factory class name for WAS.

I am connectiong from local Web application. I suppose a context factory class is not necessary. It works fine without a context factory.

Ahhh...so you get the default context factory which is some WAS class, I'm sure.
