Your container probably tries to save the existing session on a
restart (because reloading your webapp is nothing but a restart of
your application) and falls over its feets. When it comes up again,
its session information is incomplete and you get strange errors.
Try the following thing. I assume now, that you use Tomcat5:
- open your tomcat/conf/server.xml file
- look for the <Context> element for your application.
- if you don't have one, you must create one. The result should look like
this:
<Context path="/your-app-here" reloadable="true">
<Manager className="org.apache.catalina.session.StandardManager"
distributable="false" pathname="" />
</Context>
Important is the 'pathname=""'
Stop Tomcat. Nuke the contents of the work/ and the temp/
directory. Start again. See if the problem vanishes. If yes, you have
a serialization issue with Torque.
