I just updated my application to the latest versions of jars from CVS.
Due to a change in
the component package, the container jar is now required. That is fine
but when I deployed
my app and tried to start Tomcat, I get the following exception:
LifecycleException: Missing optional package Extension[avalon-framework,
implementationVersion=4.1.2, specificationVersion=1.0]
at
org.apache.catalina.loader.WebappLoader.validatePackages(WebappLoader.java:1244)
at org.apache.catalina.loader.WebappLoader.start(WebappLoader.java:645)
at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1100)
at org.apache.catalina.core.StandardContext.start(StandardContext.java:3371)
at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:785)
...
I thought that I tracked this down to the implementation version of
avalon-framework being 4.1.3
when the framework extension version in the container manifest was
4.1.2. But when I change
the required version in container' manifest to 4.1.3, I still get the
exception:
LifecycleException: Missing optional package Extension[avalon-framework,
implementationVersion=4.1.3, specificationVersion=1.0]
at
org.apache.catalina.loader.WebappLoader.validatePackages(WebappLoader.java:1244)
at org.apache.catalina.loader.WebappLoader.start(WebappLoader.java:645)
at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1100)
at org.apache.catalina.core.StandardContext.start(StandardContext.java:3371)
at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:785)
...
If I remove the framework as an extension from the container manifest,
then the error goes away
and my application works perfectly.
Any ideas? Obviously, it would be best not to have to modify the jars
before they can be used. :-)
Thanks,
Leif
