NetUI fails webapp redeploy if ServletContext attributes are carried over
-------------------------------------------------------------------------
Key: BEEHIVE-878
URL: http://issues.apache.org/jira/browse/BEEHIVE-878
Project: Beehive
Type: Bug
Components: NetUI
Versions: v1m1
Environment: Tomcat 5.0.28
Reporter: Rich Feit
Assigned to: Rich Feit
Fix For: V1
The attached webapp has a Servlet context listener which persists all
Serializable attributes to a file when the context is destroyed, and restores
those attributes when a new context is created. This allows context attributes
to be carried across webapp redeploys, which is possibly default behavior under
other Servlet containers (the spec doesn't speak to this).
Repro:
- Create a NetUI-enabled webapp.
- Drop the attached MyListener.class into WEB-INF/classes (I've also
attached MyListener.java, just for reference).
- Insert the following entry in web.xml, after the last <filter-mapping>
element:
<listener>
<listener-class>test.MyListener</listener-class>
</listener>
- Deploy the webapp, then redeploy it. One way to do this in the beehive
tree is:
ant -f {beehive home}/ant/tomcat-imports.xml redeploy
-Dcontext.path={your webapp context path} -Dwebapp.dir={your webapp dir}
-Dcatalina.username=manager -Dcatalina.password=manager
EXPECTED: the webapp is redeployed, and runs fine:
ACTUAL: the webapp deployment fails, with the following error in the logs:
java.lang.IllegalStateException: The NetUI runtime could not find the default
config file. The webapp may not function properly.
