Forum LAMS for Tech-Heads - General Forum: Re: Re: Re: Problem while saving a sequence

I did use that version now and it throws the same error. I've attached an image. Maybe that could help too.

Thanks again.

This last error looks different from the first one you mentioned.
Can you please copy-paste over here entire exception stack trace?

Cheers,

Actually is the same one. I've attached the log.

Thanks!

Again there is no org.apache.xerces.parsers.SAXParser class inside JBoss.
Can you please download attached archive and unzip it into ...\jboss-5.1.0.GA\lib\endorsed

Best,

Posted by Andrey Balan

I tried unzipping the file and put the xercesImpl.jar file inside the folder you told me (lib\endorsed). I did also recompile the whole LAMS code.

It's still giving me that error related to SAX parser.

Maybe I have to add that JAR file inside some JBOSS configuration file.

Thanks!

Posted by Felipe Peña

Sorry for keep insisting on this, but I was thinking this may happening because of the Java version I'm using on that PC. I did also try installing the same JBOSS version that's on my PC (which works), nothing happened though.

Hope you can help me.

Thanks.

I can give you only one suggestion:
remove all Java development tools (i.e.JDK, JBoss, Lams source code...),
then download same tools but pure clean versions from the web,
and follow the guide "Building LAMS 2.4+". (http://wiki.lamsfoundation.org/display/lams/Building+LAMS+2.4)

fingers crossed it will help :)

Best,
