Servlet class files not included in exported war [message #227679]

I have a dynamic web project that I have been running using an embedded
tomcat server. It is running well and I tried to export it to a war file
so that I could deploy it. The resulting war did not include any class
files. It contained jars for all dependent modules in the lib director,
the classes directory contained empty directories for each package that
contained classes. I am using Ganymede 3.4.1 with WST 3.0.3 added.

I created all of the servlets using "new->class" rather than
"new->other->web->servlet" so I tried adding a new servlet through that
mechanism. Its class file is included in the war. I could re-add all of
the servlets using the servlet path and I suspect that will take care of
those. However, there a supporting POJO classes in the project that are
required, which I think will still be left behind.

Is there a better/alternative way to get the servlet classes included?

What do I need to do to include the support classes in the jar?

Thanks for you help

It sounds like your POJO source files are not in the right location in the
web project. The default location is <project.dir>/src unless you changed
it at project creation or later in project properties.

Can you compare the location on disk of the original POJO source file with
the location of the source file created by the new source file wizard? It
doesn't matter which wizard you use to create a java source file, but the
location that the file is placed at does matter.

Konstantin,

Thanks for the reply. Unfortunately all of the java source files (POJOs,
servlets added as classes, and the test servlet added as a servlet) reside
in packages stored under <project.dir>/src. Also, based upon another post,
I checked .settign/org.eclipse.wst.common.component and it correctly
identifies src as a wb-resource as shown below.

<wb-resource deploy-path="/WEB-INF/classes" source-path="/src"/>

Any other ideas?

I went ahead and removed all of the servlets that were just added as
classes and then added new versions using "new->other->web->servlet". This
fixed the problem. Not only are the servlets all now being exported, the
POJOs that they reference are exported. It looks like some dependency
checking is occurring on export to WAR.

Thanks for your help.

Hmm - I run across the same snug - in my case it is after I converted my project to maven (partly manually). The project is deployed on JBoss fine locally (Right click > Run as ... > Run on server) but when I hit Export > WAR file the servlet classes do not come along in the ride.

Funny thing: if I clean the project then the classes are added in the target/ directory and are packaged in WEB-INF\lib\classes

EDIT: if I shut down the server and then hit Run on server I get resource not found - I need to clean the project, then clean the server in servers view to have it deployed (essentially to create the classes). Makes sense - so the only remaining question is why clean ?

The maven dependencies as well as the contents of the WEB-INF\lib folder end up in the war at WEB-INF\lib always - whether I clean or not - but only if I clean the project I see my classes.

What could be wrong ? Why is cleaning necessary ?
