I am trying to run the tomcat example of JNDI datasource from the following link:
http://tomcat.apache.org/tomcat-7.0-doc/jndi-datasource-exam ples-howto.html
I have created a data source through data source explorer and able to access it. When I run the jsp page I get the following error. As the link says that I am suppose to have a context.xml in META-INF, but when I created that my tomcat won't start,Later on I have searched the internet for solution but I can't seem to find any solution that fixes my issue. Any help would be appreciated.
