How to develop JMS Java Application.

[Former Member]

Now,I develop Java Application(J2SE stand alone) to send JMS for JMS Adapter(sender) verification.

But fatal exception is displayed when I execute Java application.

Error is rellated to following code.

InitialContext context = new InitialContext(properties); //←(SendJMS.java:41)

Are there wrong points in this code or other necessary settings(for example on Visual administrator) ?

I think that Java Appli can send Java Message to JMS provider in J2EE(XIserver) by using JNDI.

Is my thougt wrong?

Sorry poor English.

Best regards.

Hi Abhishek Agrahari

Thanks for your help.

I added sapj2eeclient.jar,naming.jar,exception.jar and logging.jar to classpth.

As a result, I successed Java Message to JMS Provider from Stand Alone Java Application!!

Thank you.
