Jboss 7.1.2 Final, Subsonic and string-1.1.0.jar parse error

pathduck Aug 8, 2012 5:56 AM

Hi,

I'm deploying the Java media streamer Subsonic ( http://www.subsonic.org/ ) on JBoss 7.1.2 Final and get a parse error on string-1.1.0.jar on deployment:

2012-03-26 18:58:54,437 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-2) MSC00001:

(note, error is from 7.1.1 Final but it's the same in 7.1.2, I just don't have access to logs atm)

The problem within string.jar seems to be the bodycontent tag in taglib.tld containing uppercase EMPTY:

<bodycontent>EMPTY</bodycontent>

If I change this to lowercase 'empty' the WAR deploys fine.

So what is the problem here; should the taglib.tld for string-1.1.0.jar be changed, or is JBoss too strict in its's parsing of this file?

This is on JBoss 7.1.2 Final, running on Debian with Java 1.6.0_18.

On AS6 you could disable the TLD validation, not sure you can do it on AS7 anymore.

Thanks for the reply Nicklas

Not sure where this string jar is from, or if it's something the Subsonic dev can change himself. If not, there should be a way for JBoss to not be se strict on the case of a TLD, any ideas?

Woah, a blast from the past

Anyway, no I did not receive a reply from the developer of Subsonic, and anyway he just uses a third-party string.jar. So the question that would be nice to get answered is whether it is necessary for Jboss to be so strict on case-sensitivity when validating TLDs, and whether it is possible to disable it in JBoss 7 - though it appears not.

I guess the jury is still out on this one.

I open a jar and change the value of <bodycontent> to lowercase "empty" and repack. It's not a fine solution, but works.

That's what I did as well - not elegant but it's not like I have to do it all the time since there is not a lot of new releases of this software

I would look through the JIRA database and file a feature request if one is not found (slacking of validation) as it gets annoying having to open JARs and fix them (especially if the JAR author is lazy and doesn't fix it in new versions)

I'm struggling with the same problem, but I have not found any possibility to turn off the validation. Is there any possibility to turn it off by now.

I'm not aware of any progress in the area. Or if it's being considered at all.
