Issue: Getting resource exception at runtime attempting to connect to a websphere mq to get a jms message using spring. I just can't determine what I am missing?
Description: Attempting to set up the example here. Spring MDP Activation Spec for Websphere MQ.

Maven Dependencies Note: Version numbers for the ibm jars looks odd because I created a local repo in my project to add the 3rd party libraries. I'm taking the ibm jars from my local Websphere SDP version for Websphere 7.5 . I also tried directly adding the jar dependencies on the STS spring package and had the same error.

Updated- Solution: Required IBM Jar dependencies required.
回答1:
Generally the easiest way to get the classpath right in RAD or other IBM tools for applications that are ultimately going to be deployed to WAS is to load the server runtime library of the WAS version into your app.
It is very easy. Go to the app properties page, go to build path, libraries tab and click add Library. You will see the screen shot below. Choose server runtimes and as long as you have installed the correct WAS versions as part of RAD, you will see their runtimes.
This is generally the best way to go since it allows you to keep you WAS libraries separate from your app, but to still make them available for compilation. The worst thing you can do is embed WAS libraries as part of your app. If you do this and you deploy your app to different versions of WAS, then you will get weird classpath or weird runtime errors. On top of that, things that were working might stop working after fixpacks get applied or other software adjustments.
If you add the server runtime library, then this is what your app will look like in RAD.

Looks like you are missing some dependencies here. Can you try to add javaee-api to your pom file?
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
<version>6.0</version> <!-- or take version 7.0 if needed -->
</dependency>
