LoadRunner WebSphere MQ scriptting issue

Hi everyone,

I'm trying to make some jms calls to IBM MQ using web services protocol. I'm always getting cannot instantiate class error no matter which JNDI connection factory I select.  I tried changing the RTS to use external JVM but it always says "The specified JVM path "C:\Program Files (x86)\Java\jdk1.8.0_191\" is not valid; the default path will be used instead." Can someone guide me with this?

Thanks for reading.

Regards
