Missing class jumpstart.loadlookupinhdfs_0_1.LoadLookupInHDFS

I'm using Talend v5.5.1 Big Data Insights Cookbook v1.0 tutorial
Trying to run the Twitter example in section 4 produces the following error:
Error: Could not find or load main class jumpstart.loadlookupinhdfs_0_1.LoadLookupInHDFS
I can see the source file at /opt/talend/Talend-Studio/workspace/.Java/src
Please advise

It looks like Talend Studio does not recognise the Java version correctly and does not find a compiler.
Take care you have set the JAVA_HOME var to a JDK7.
Next open the preferences and look at Java-Installed JREs and add here your JDK.
After adding this go to the Execution Environment setting and set for JavaSE 7 set matching JDK.
This should fix the error.

Hi Michael,  What Hadoop Distribution are you using and are you using VMware or VBox?  Can you open a terminal window and type java -version and post the results?

Appreciate any help,

Thanks for the info - I am looking into the issue.  However, you may be interested to know that we just released our latest versions of the Big Data Sandbox.  It includes our latest version of Talend Platform for Big Data (v. 5.6.1) with either Cloudera 5.2, Hortonworks 2.2 or MapR 3.1 and has all the same scenarios.  You can download at www.talend.com/talend-big-data-sandbox
