instance has been stopped. could not load
oracle.toplink.essentials...
I can't quite predict with certainty when this error will occur:
86899 Feb 28, 2009 10:05:50 PM
org.apache.catalina.loader.WebappClassLoader loadClass
86900 INFO: Illegal access: this web application instance has been
stopped already. Could not load
oracle.toplink.essentials.internal.localization.i18n.LoggingLocalizationResource.
The eventual following stack trace is caused by an error thrown for
debugging purposes as well as to attempt to terminate the thread which
caused the illegal access, and has no functional impact.
86901 java.lang.IllegalStateException
but generally restarting tomcat, and some combination of undeploy/
redeploy fixes the problem. (I'm using NB 6.1, which automagically
deploys the .war) I'm not entirely whether undeploying the app does
anything or not, I don't see why it would, but it seems to help.
>From what I've read the general solution is to just restart tomcat. What
does the error mean?
Also, just to clarify, if I'm using toplink for JPA then the toplink
jars, and whatever I'm using for jdbc, need to be copied to tomcat as per:
http://wiki.netbeans.org/DeployREST2Tomcat55
(instead of derby I'm using mssql.jar)
thanks,

Uproot your questions from their ground and the dangling roots will
be seen. More questions!

Yeah, I've just been ignoring the INFO, as you point out and it doesn't
seem to matter. Nebeans undeploys and redeploys, and maybe restarts
tomcat as well. I suppose settings for those actions would be in
netbeans.
Sounds like something fairly safely ignored?
thanks,

LOL. I took it as that, but also thought there might be something to it,
too. I swear the "tutorials" on JDBC settings for mssql are wrong.
Anyhow, thanks for the help.

Nothing wrong with MSSQL; it has its quirks, just like every other DB.

Glad you saw that. It seems like toplink is required for JPA? Do you
have suggestion beyond "don't use mssql" because mssql is what my school
uses, so I have to connect to that db.
Maybe I should setup some sort of derby thing? I'm not sure how that
works, but I'm guessing that it would add a layer of abstraction.
However, I'm not sure that would get me anywhere. Kinda a java question
rather than tomcat.

And we can't predict what Tomcat version you're running on. You might be a mentat, but the rest of us aren't.

It looks like the webapp was already on the way down when the above message (note that it's INFO, not ERROR) was displayed. You may have run into the problem of your logging environment trying to reinitialize itself when it shouldn't. You can try setting the system property:
org.apache.catalina.loader.WebappClassLoader.ENABLE_CLEAR_REFERENCES
to false, but that may end up with a webapp that can't be reloaded. Doc is here:
