    Hi Experts,

    I am using webMethods IS 8.2.2. I want to do JMS Communication within the IS, by using sendStream & receiveStream services.Here i created JMS connection alias with NoTransaction. created Client group and specified in JMS Connection alias.

    I am sending stream data in Sender Service by using "pub.jms.wmjms:sendStream".
    created trigger for the particular destination(queue, that i have created with client group and specified in JMS Conn alias).

    specified subscribing service that i have created with "pub.jms.wmjms:receiveStream"
    When i trying to run the sender service i am getting the following error. Help me


    trigger failed: com.wm.app.b2b.server.ServiceException: java.lang.NullPointerException

    Hi,

    As per the documentation, the webMethods JMS Provider (the webMethods message streaming feature) allows you to stream large amounts of data or a large file from a message producer to a message consumer. You can only send and receive large messages from Integration Server when working with the webMethods JMS Provider.

    Here I suspect you are trying to send stream data/message which is smaller in size where fact is that you can only send/receive stream data/message which is large in size (more than 1 MB). You can try with large data/message and share the result.

    Hi,

    I also configured the same on my local system and it is working fine. I suspect some configuration issue at your end. Please make sure that you have followed all steps to configure JMS using MWS. See link for reference.

    http://idnxchange.com/webmethods-blogs/tags/27/ and check JMS Provider Blog.

    also make sure that you have created created tested (on IS):
    i. Settings > Messaging > JNDI Settings --> JNDI Alias Name
    ii. Settings > Messaging > JMS Settings --> JMS Connection Alias Definitions

    If possible share the details of configuration at your end.
