Monitoring WebLogic Using JMX - Security issue

Question

Hi I'm trying to run the following code, which try to connect to 2 domain and retrieve their names. When I try to connect to each domain separately, everything works fine. When I try to connect to both domain I get a security exception:
MBeanHome home1 = null;
MBeanHome home2 = null;
try { 
     Environment env = new Environment();
     env.setProviderUrl(url1);
     env.setSecurityPrincipal("weblogic");
     env.setSecurityCredentials("weblogic");
     Context ctx = env.getInitialContext();
//getting the local MBeanHome
     home1 = (MBeanHome) ctx.lookup(MBeanHome.ADMIN_JNDI_NAME);
     } catch (Exception e) {
     System.out.println("Caught exception"+e);          }
     try { 
     Environment env = new Environment();
     env.setProviderUrl(url2);
     env.setSecurityPrincipal("weblogic");
     env.setSecurityCredentials("weblogic");
     Context ctx = env.getInitialContext();
//getting the local MBeanHome
     home2 = (MBeanHome) ctx.lookup(MBeanHome.ADMIN_JNDI_NAME);
     } catch (Exception e) {
     System.out.println("Caught exception" + e);
     System.out.println("domain1: "+home1.getDomainName());
     System.out.println("domain1: "+home2.getDomainName());
And the exception I get is:
java.lang.SecurityException: [Security:090398]Invalid Subject: principals=[weblogic, Administrators, IntegrationAdministrators]

try enabling the trust between the weblogic server domains.
http://e-docs.bea.com/wls/docs81/secmanage/domain.html#1173731
If you want two WebLogic Server domains to interoperate, perform the following procedure in both domains:
Expand the Domains node (for example, Examples).
Click the View Domain-Wide Security Settings link on the Domain-->General page.
Select the Security Configuration-->Advanced tab.
Uncheck the Enable Generated Credential attribute.
Enter a password for the domain in the Credential text field. Choose the password carefully. BEA Systems recommends using a combination of upper and lower case letters and numbers.
Confirm the password by entering it in the Confirm Credential text field.
Click Apply
