JDOM Comment data cannot start with a hyphen

[amin.lalji]

Trying to deploy on JBOSS... seems all lzx files are suffering from this behaviour... replaced all <!--- with <!-- ... just wondering of anybody is experiencing these issues...

I observe the same behaviour (using JBoss 3.2.3). I think it's a bug in the used XML parser. The XML spec says about comments:

Comment::= '<!--' ((Char - '-') | ('-' (Char - '-')))* '-->'

So a comment starting with "<---" should be ok. I will try if upgrading the parser libs helps (one day)...

I have the same problem trying to deploy laszlo on JBOSS...

How usefull will be to use EJB, and laszlo...
I wonder if there are already projects out there to bundle
Laszlo + JBOSS + Apache + PHP + SLL + MySQL

How lovely would be something like http://www.BigApache.org or The Saint WAMP including laszlo Core on JBoss... or better...
LASZLO CORE + JBOSS/TOMCAT + PHPSERVLET all JAVA CROSSPLATFORM w/o installations ready to go.

Any suggestions?

after a long learning curve I have managed to get Laszlo core + Tomcat + Apache + PHP + MySQL to sing together .. see earlier threads .. but I've not tried JBoss - just another servlet engine

so yes .. the entire orchestra is possible ..

I'm having the same problem here. Trying to run Laszlo on JBOSS on SUSE 9.1.

Can you be more clear about what component is generating this error? Should I try a different version of JBOSS or is it some other library JBOSS is using?

I would really like to get this going so I can play some. I would prefer not to change all the component files to only have two hyphens. It makes upgrades and compatibility with other users problematic.

Thanks.

Same problem with JBOSS, in Mac OS X, Win32 and Suse 9.1.

EJB and laszlo seem to me like a good team, would it be possible?

Where is this parser located? Is it part of Laszlo, JBOSS or some other component?

The Laszlo-WAR contains a Xerces.jar, but I guess, that this jar is not used if deployed in JBoss. My JBoss-Distri contains a xerces.jar in path_to_jboss/lib, which is probably used. And the JRE itself contains a parser lib.

Which one is used...? I don't know.

If I had time right now, I would try the following:
* Remove all xerces and crimson jars from all directories
* Create a new directory somewhere else and put the xerces.jar from the lps war in it
* Start the JBoss inside a JVM with parameter "-djava.endorsed.dirs=path_to_newly_created_dir"

Maybe this (or a variation) works...

I was able to fix this problem by copying the file, $LASZLO_HOME/lps-2.2.1/WEB-INF/lib/jdom.jar, to $JBOSS_HOME/lib; thereby overwriting the version of JDOM used by JBoss. WARNING: I haven't done extensive testing, so I can't guarantee that this doesn't break something in JBoss. Oh, and I'm currently using JBoss 3.2.3 on Windows XP Pro.
