Problem deploying VOSA (vosaocms-0.3-20.02.2010.war) - SOLVED

Hi there ... 

First of all, well done VOSAO awesome job.

Yesterday I downloaded the vosaocms-0.3-20.02.2010.war file and unpacked 
with Eclipse. Then I though that the Eclipse plugin will do its job and 
deployed easily the war, unfortunatelly was not the case :(

However, after reading some post here and there I finally could deployed 
the CMS locally and on the cloud (appengine).

Problems and solutions:

1. I had some problems with the java.home variable will I was updating my 
applications  through the appengine. Because I installed the JDK in 
"C:\Program Files\Java\jdk1.6.0_13" and the process was liking the compiler 
and some files in "C:\Program Files\Java" so what I did might not be a 
clever or efficient way but it worked :P 

Solution (in my case): I had to copy content of "C:\Program 
Files\Java\jdk1.6.0_13" to "C:\Program Files\Java", yes all the bin, lib, 
etc folders.

2. After this problem I come cross with another. The update process said 
that the application was deployed successfully. However, when I accessed my 
application which was already deployed in the appengine. It showed and 
aweful 500 Internal Server Error. I went to the logs and try to track what 
was happening. The problem was related to the initialization of the context 
specifically with the 'persistenceManagerFactory' log as follows:

org.springframework.web.context.ContextLoader initWebApplicationContext: 
Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating 
bean with name 'persistenceManagerFactory' defined in ServletContext 
resource [/WEB-INF/applicationContext.xml]: Invocation of init method 
failed; nested exception is javax.jdo.JDOFatalInternalException: Unexpected 
exception caught.

Then almost at the end the cause was:

"Caused by: org.datanucleus.exceptions.NucleusException: Plugin (Bundle) 
"org.datanucleus.store.appengine" is already registered. Ensure you dont 
have multiple JAR versions of the same plugin in the classpath. The URL 
"file:/base/data/home/apps/canberraservices/1.340205870101291195/WEB-
INF/lib/datanucleus-appengine-1.0.5.jar" is already registered, and you are 
trying to register an identical plugin located at URL 
"file:/base/data/home/apps/canberraservices/1.340205870101291195/WEB-
INF/lib/datanucleus-appengine-1.0.3.jar.

SOLUTION: The vosaocms-0.3-20.02.2010.war includes to jars the datanucleus-
appengine-1.0.5.jar and the datanucleus-appengine-1.0.3.jar. I just deleted 
the latest and redeployed and it worked.

Cheers to everyone ...

Promote VOSA is what I was waiting for a real open source CMS in the Cloud 
and in Java ...

Thanks ways .. keep working ... :)
