Desperate Plea - FileNotFoundException from ValidatorPlugIn
Okay, now I'm desperate, and you know I wouldn't come bother you if I had
any other choice. ;)
But I have a webapp that works perfectly well on Windows where I develop,
and then when I make a .war file and deploy it to HP-UX, it will not start.
This began with Struts 1.2.4 and continues to happen with 1.2.5. (It worked
on HP-UX with Struts 1.2.0 but dropping back will cause some pain at this
point.)
The (Tomcat) localhost log file says:
2004-11-01 12:31:53 StandardContext[/benauth-dev]: Servlet /benauth-dev
threw load() exception
javax.servlet.UnavailableException: Cannot load a validator resource from
'/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml'
And in the log for the application, I see:
12:31:53,712 - INFO org.apache.struts.validator.ValidatorPlugIn - Loading
validation rules file from '/WEB-INF/validator-rules.xml'
12:31:53,713 - INFO org.apache.struts.validator.ValidatorPlugIn - Loading
validation rules file from '/WEB-INF/validation.xml'
12:31:53,833 - ERROR org.apache.struts.validator.ValidatorPlugIn - JAR entry
org/apache/commons/validator/resources/validator_1_1_3.dtd not found in
/opt/hpws/tomcat/webapps/benauth-dev/WEB-INF/lib/commons-validator.jar
java.io.FileNotFoundException: JAR entry
org/apache/commons/validator/resources/validator_1_1_3.dtd not found in
/opt/hpws/tomcat/webapps/benauth-dev/WEB-INF/lib/commons-validator.jar
Does anyone have any idea why this is happening? The dtd is present in the
.jar file, so the "real" problem must be something else, I just have no idea
what.
Thanks in advance,

Just a wild-eyed guess, and one with little probability of correctness, but if
getResource is being called from a class, that is derived from in another
package, and the derived class is the one that is instantiated, you will
probably have path problems due to relative path rules.

Thank you! That works. Earlier I was vaguely remembering that we used to
have to configure something in web.xml... but that turned out to be tld's,
and I never got as far as figuring out where to put a "loose" dtd file.

I'd like to blame the .jar file, except that I can deploy
struts-examples.war on the offending server, and the module that has
validation works fine. I copied commons-validator.jar from the working
struts-examples webapp over to my own and stopped/started-- same error.
This is just plain weird. But HP-UX is like that sometimes. ;)

Exploded directory.
Thanks again! Now I'm off to convince Ant to extract the dtd or copy it
from somewhere to 'classes' so I don't lose it every time I clean and
compile.

Have you tried putting a copy of the DTD in WEB-INF/classes? Might
be a workaround. It seems peculiar that it is telling you exactly
where in the classpath it isn't finding something -- so it's not (as
you noted) that it isn't there. Maybe if you made a fresh
commons-validator.jar? Maybe there's something quirky about the JAR
you have that your app server doesn't like.
Is it trying to read the DTD from a WAR? Or an "exploded" directory?
I had some problems once trying to deploy a simple webapp as a WAR to
Weblogic 6 under Solaris where it couldn't read resources with the
ClassPath loader even though it could read them just fine when I
instaleed the same app in "exploded" form.
