Hi, last week, I was having fun with trivial examples accessing a datasource with the standard taglibs with success. Since everything was working perfectly in jsp form and morale was high, I decided to precompile my web app with TCD and deploy it again in tomcat 7.0.6
I installed ant, fetched dependencies, installed TCD set up the project's properties and fired "ant compile" away. 2 questions: A small problem appeared with addWebXmlMappings="true". apparently ant reported: \build.xml:67: jasper doesn't support the "addWebXmlMappings" attribute Apparently ant 1.8.2 with all dependencies fetched *today* isn't enough? Bypassing this problem by manually merging the servlet mappings from generated_web.xml to web.xml and deploying, I get an exception when accessing my page: java.lang.NullPointerException at org.apache.jasper.runtime.
