Hi,
when I want to log in to the EM I'm getting the following error:

This OC4J is configured to make JMX connections via RMIS and fall back
to RMI if the RMIS port is not configured. The RMIS connection on the
OC4J instance home on Application Server assoa.locahost is configured
but a connection could not be established. The JMX protocol is
specified by the oracle.oc4j.jmx.internal.connection.protocol property
in opmn.xml

Can anyone help me with this problem?
