I'm trying to deploy a web app from an "exploded directory" in
Weblogic 9. The app worked just fine in Weblogic 8. I'm getting this
message:

[J2EE:160177]The application at
"D:\bea9\user_projects\domains\local-idcfD\servers\idcfD1\stage\Freqs\app"
was not recognized as a valid application type. If this is an EAR
file, please ensure the META-INF/application.xml exists. EJB-JARs
should have a META-INF/ejb-jar.xml. WAR files require a
WEB-INF/web.xml, and RARs require a META-INF/ra.xml. A JMS deployment
should be an XML file whose name ends with "-jms.xml". A JDBC
deployment should be an XML file whose name ends with "-jdbc.xml". For
other application types, please consult the WebLogic Server
documentation.

That seems to tell me that it doesn't think I have a web.xml file in
the WEB-INF directory, but I do. So maybe its a syntax issue. This is
a simple app and the web.xml is short. Here it is:

Any ideas as to what I'm doing wrong?
