something wrong creating datasource after war deployement
Hi
something strange appends with an application
On tomcat 5.5.20 (same behavior with tomcat 5.5.17)
I deploy an application copying an unpacked war directory into webapps
directory. I add a datasource updating the META-INF/context.xml and
WEB-INF/web.xml like tomcat how-to. All works perfectly, no problems.
In another tomcat I copy the war of the same application in the webapps,
the war is unpacked . I add the datasource updating the
META-INF/context.xml and WEB-INF/web.xml and I can't use this datasource
: "org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create JDBC
driver of class '' for connect URL 'null'"
witth windiff I compare the two directory and they are identical, the
only differences is in one the webapps directry has only the unpacked
directory and the other has unpacked and war directory.
I need help to understand, thanks
Arnaud

Posted by David Delbecq <de...@oma.be>.
The context.xml inside war will anyway override any custom datasrouces
your may have created after previous deployment, so i think it's not a
viable issue to use both (one will anyway always override the other).
Maybe you can configure your custom datasource at server level (server.xml)?

You need to update the one in conf/Catalina/[host], since that overrides
the ones in the .war and the unpacked directory.

It wouldn't surprise me if Tomcat is doing some merging of the two
<Context> elements, rather than enforcing a complete override.

Tomcat automatically creates the conf/Catalina/[host]/[appname].xml file
from META-INF/context.xml only when deploying apps packaged in .war
files, regardless of the setting of unpackWARs; it does not create one
in the conf directory for apps that are deployed in an unpacked form,
although you may place your own in conf/Catalina/[host] to override the
one in META-INF.

thanks,
I updated the META-INF/context.xml in the unpacked directory,
this is strange because when I update the META-INF/context.xml, I can
see newly datasources in the tomcat admin webapps (but with blank
driver class and url info).
If I update META-INF/context.xml in application without war file in
webapps, everything works and I can see newly datasources in the tomcat
admin webapps with driver class and url.

As David mentioned earlier, when a .war is unpacked, its
META-INF/context.xml file is copied to
conf/Catalina/[host]/[appname].xml, and that becomes the active copy.
Changing the one in the unpacked directory will have no effect, since
the one in the conf/Catalina/[host] directory is defined to override the
one in the app.
Which one are you updating?

Re: something wrong creating datasource after war deployement

I need to provide a context.xml in the war because there are default
datasources configured for my app., but it must be possible to add
datasources after app. deployment.
Like you, I think there is a conflict between context.xml in war and in
unpacked directory (because wtihout war all works as expected) but I
don't know if it is tomcat bug or if it is problem in my configuration,
maybe there is context param allowing to force to tomcat to use
context.xml in war or context.xml in directory.

Re: something wrong creating datasource after war deployement

If you want to edit the context.xml yourself, remove it from the .war
file. I suppose there is a conflict between the context.xml you deploy
yourself and the one inside the .war. I think when you deploy an
unpacked directory the META-INF/context.xml file is ignored. (Not 100% sure)

Re: something wrong creating datasource after war deployement
Posted by Arnaud MERGEY <am...@sunopsis.com>.
Thanks for reply, my db is Oracle 9i
The problem isn't a security or driver problem, I have tested also in
the same tomcat, in webapps:
- Cpying the unpacked version only, modify context and web.xml, all
works perfectly.
- Removing in the same tomcat the application, copying the war file and
modify context.xml and web.xml in the unpacked directory, I have the
org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot
create JDBC driver of class '' for connect URL 'null'
- Removing the war and copying the unpacked version only, modify context
and web.xml, all works perfectly.
I have tested tomcat 5.5.20 5.5.17 many times and on several tomcat
instance, I have always the same behavior.
In my case using war deployment prevent me to update manually
context.xml to add datasource. I need to use admin webapp or to copy
unpacked directory, not the war himself.

Get the full stacktrace of exception to know when this happen. If both
install are same, maybe one is on a server that has no access to the db
(check the db security settings).
Also, what did you compare with windiff? The webapp directories or the
full tomcat install directores? Your META-INF/context.xml should have
been copied by tomcat to conf/Catalina/<hostname>/<webappname>.xml Check
those are correct.

Check if there are any differencesx in the directories
- $CATALINA_HOME/server/lib
- $CATALINA_HOME/common/lib
- $CATALINA_HOME/shared/lib
My guess is, that in one of those directories there's a jar-file
containing the database driver that is missing in your other
Tomcat-installation.
BTW., what dbms are you using?
