Loadrunner Erorr JMS send message queue

Hi there!

I'm trying to develop a script with a JMS request against a IBM MQ queue with VuGEN.

I added the next jar file "rt.jar" because it was giving me a lot of sending message errors but once I added it, it continued failing due to this error:

Error: Failed to send message <?xml version..... "nameofthequeue" due to the following exception : javax.naming.NamingException: Failed to initialize the ORB [Root exception is java.util.MissingResourceException: Can't find com.sun.corba.se.impl.logging.LogStrings bundle from ] 


Looking for the missing library of the Java method "com.sun.corba.se..." I found that "rt.jar" solves this problem but it is not working, at least adding this (and another libraries) file to the "Classpath" of the Runtime Settings in Vugen.

If someone could help me please I would apreciate it.

Thanks in advance.

Regards
