Subject: Weird stack trace when reloading a webapp
Hi,
I use the ant deploy target :
<deploy url="${url}" username="${tomcat.user}"
password="${tomcat.password}"
path="/{webPath}" localWar="${warPath}" update="true"
config="${contextPath}" />
But in catalina.out, I have the following stack trace :
INFO: Deploying web application archive dotw-trans.war
2008-08-07 15:04:38,942 INFO impl.BasicTilesContainer : Initializing

stack trace is caused by an error thrown for de
bugging purposes as well as to attempt to terminate the thread which
caused the illegal access, and has no functional
impact.

SEVERE: Error filterStart
Aug 7, 2008 3:04:40 PM org.apache.catalina.core.StandardContext start
SEVERE: Context [/dotw-trans] startup failed due to previous errors
Any idea on the Could not load
META-INF/services/org.apache.xerces.xni.parser.XMLParserConfiguration.
My en is :
- apache-tomcat-6.0.18
- jdk1.6.0_06
- solaris 10
Any idea ?
Thanks,

Oliver is that the whole error message or did you abreviate it?
Does is say anything about a POST...
I tell you why, on complex applications I've seen something similar...
Anyway try this.... before you redeploy... open /manager/html and UNDEPLOY
the old one... then run your script...
If it is the same thing... you wont get the error because its actually
happening in the undeploy...
If that works then add another section to your ant script... first
undeploy... then redeploy...
If it is the same thing... I've only noticed it on very complex apps....
Other thing I've noticed is that even when you get this weird message...
the redeploy does work.
And you cant debug it... because TC is killing the thing... ide wont trap
it...
And I think it only happens when there are classloaders in the webapp
classloader... which would explain why the webapp class loader cant let
go... the child still has references... anyway try the above, and I dont
think its too serious... its a last complaint before it gets a bullet
between the eyes ;)
.... maybe its the same thing...
Oh... to explain your question... sorry I got excited there....
findResourceInternal
INFO: Illegal access: this web application instance has been stopped
already. Could not load META-INF/services/org.ap
ache.xerces.xni.parser.XMLParserConfiguration.
What this means is that something in the application is trying to load a
resource... like applications load Icons ona stuff... but the class loader
in the application then asks Tomcats class loader to get it from the class
path.... (something like this, could be less or more complex)... but because
that classpath has been released already.... they screwed and dont know what
to do... its like a classloader forgetting where jar files are... thankfully
some clever programmer put the reason in... the web app has already gone...
which maked me think theres another classloder in their somewhere...
something like that ;)
Its a final death throw....
