Ant-generated WAR file produces odd results compared to Eclipse results

[veraction]

I typically develop my application with Eclipse WTP, and run Tomcat using their Servers plugin tool. I have now tried to use an ant build.xml file to create a warfile for distribution purposes.

However, when I load up the warfile by placing it in webapps/ then starting tomcat, it produces odd results. This SimpleFormController view doesn't work at all.
When I was using Eclipse to run this application, this login screen is fully functional (and there is no ${status.expression} text).

It doesn't seem totally broken, because for a non-form Controller which just retrieves data from the DB via Hibernate, it works fine.

Anyone have any ideas as to what could be wrong for my WAR file creation process?

In my logs, I don't see any warnings or anything serious. Using this

log4j.logger.org.hibernate.tool.hbm2ddl=DEBUG
log4j.logger.org.springframework=DEBUG
org.apache.catalina=DEBUG
log4j.logger.courses=DEBUG

With Ant, my classpath is the same for both building and for the WEB-INF. It is pointing to a directory containing these jar files:

$ ls WebContent/WEB-INF/lib/ | cat
activation.jar
antlr-2.7.6rc1.jar
asm-attrs.jar
asm.jar
cglib-2.1.3.jar

The logs specific to displaying this login screen seem to be okay to me:

Any ideas? Thanks

I now realize that the other form type views seem to be fine. So, everything is fine except for this login screen which apparently doesn't bind, or something.

Still debugging..

Problem Fixed

I fixed the problem, yet I don't understand it yet.

I was using the implicit commandName = 'command'.
I changed it to use commandName='login' in the bean xml file, than replaced the word 'command' with 'login' in my login.jsp page.

It now works

I have no clue why..

[edit] and remember that having commandName='command' works fine for eclipse, just not the ant-generated WAR file
