Test web application
Hi,
I have a web application (attached) that specifies env-entry in the web.xml.
The env-entry does not specify env-entry-type, but specifies injection-target.
When deploying that web application, the exception below is thrown:
Caused by: java.lang.NullPointerException

org.apache.catalina.deploy.NamingResources.addEnvironment(NamingResources.java:254)

Servlet Specification, 14.4 Deployment Descriptor Diagram, describes that use
case and how it should be handled:
"
env-entry element
If an injection-target is specified for the environment entry, the enventry-
type may be ommitted or MUST match the type of the injection target. If
no injection-target is specified, the env-entry-type is required.
"
I would like to propose a patch (attached) that solves this issue.
I'm looking forward for your comments.
Thanks
Violeta
