JMXConnectorFactory.connect Hangs periodically

Question

Whenever trying to establish a JMX connection to a remote managed device there appears to be a hang when invoking the JMXConnectorFactory.connect. This behavior is exhibited operatically but there have been several successful connections to the same remote device prior to the hung attempt. We are using the optional protocol for JMX which is JMXMP so additional dependencies on the jmxremote.jar and jmxremote_optional.jar. I know there are some timeout properties that can be set as apart of the environment map that is passed into the connect but it seems to have no impact on the hang. From researching there have been several enhancements to both of these jars and we are currently on the 1.0 version. Would upgrading to the 2.0 version potentially solve this issue? Would the timeout property be recognized? Switching from 1.0 to 2.0 is a non-passive change as well which could complicate things.
Configuration:
JRE: 1.5.0_15
JMX Protocol: JMXMP
SSL Enabled
Thanks for any help in advance.

hi alan_mehio
Thank you for the reply
ApplicationContext context = new ClassPathXmlApplicationContext(
new String[] {"classpath:context.xml"});  The above line throws aqn error "cannot convert ClassPathXmlApplicationContext to ApplicationContext
so i have the changed the code to
{code}
     ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(
                    new String[] {"classpath:context.xml"}); {code}
After changing to this i got an error that org.springframework.beans.BeansException is indirectly referenced
I solved the issue by downloading & adding the spring-beans.jar to the classpath.
FYI
But the above line is also throwing an exception
java.lang.NoClassDefFoundError: org/springframework/context/support/ClassPathXmlApplicationContext
Even though the jar files are in the build path. Please tell how to overcome this
Thanks in advance
