Hi all,

I'm using Java Studio Creator 2 for development, managed to code and deploy 8 portlets with no problem at all BUT, data binding problems.

All my databindings don't work, no matter what I do , I've used plain JDBC API to access my datasources and bound manually all componentes as an alternative solution, not elegant but functional!

Also downloaded Liferay 4.4 to see if is my version (using Liferay 4.2) but after deploying one test portlet with a dropdown bound to a datasource, I obtain same error as with 4.2 version, like this:

2008-02-28 13:54:12,343 [http-8080-Processor23] ERROR org.apache.catalina.core.ContainerBase.... - Servlet.service() for servlet jsp threw exception
javax.faces.el.EvaluationException: java.lang.RuntimeException: org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for connect URL 'null'
at com.sun.faces.el.ValueBindingImpl.getValue(ValueBindingImpl.java:206)
at com.sun.faces.el.ValueBindingImpl.getValue(ValueBindingImpl.java:154)
....................................................................

My test portlet works ok with Pluto portal, bound with Java Studio Creator 2, data bindings are all OK.

I've searched lots of forums for days, but none seems to know the answer. I'm really lost, could some specialist explain why Tomcat doesn't know where my datasource is?? or how can I add manually datasource definition to Tomcat??

Thanks in advance!!
