Application will not deploy since upgrade to new SDKs

Hi,

since I have upgraded the SDKs, I simply can not get the deployment to work without getting some type of error. The latest error I get is:

2014 10 21 14:58:42#+00#ERROR#com.sap.core.services.accessor.tomcat.support.DelegatingObjectFactory##anonymous#fs-watcher##a0d0fd2c0#test#web##Exception is thrown by facroty [com.sap.jpaas.service.persistence.core.JNDIDataSourceFactory@56f316ec] during retrieving object instance.

I am not using JPA. However, I did use JPA initially, but now use JDBC calls instead. I do not have a persistence.xml or anything.

Can someone please help. I am trying different things over the last few days, but still no success. 

regards,

Keith
