Problems with the WCM preview tutorial

Hello,I downloaded and installed the WCM v2 preview on Linux using Weblogic 9.2 and Oracle 9iR2 and all appears to work fine.However, when following the tutorial I encounter the error below when uploading the 'company-footer.xsd' as part of creating a new web formlease correct the errors below the

what browser version are you using?

Re: Problems with the WCM preview tutorial

I have tried Firefox 2.0.0.1 on Windows 2000 and Firefox 2.0.0.2pre on SuSE 10.2.

Both give the same error.

I don't think the problem is client side as a packet trace show the form submission of the xsd to the UploadFileServlet

it looks like you're right - it does seem like the upload is working properly. just to make absolutely sure, can you try it with IE6 on windows or firefox 1.5 on any other platform.

My hunch is that the problem is actually with your server environment though. it seems as if you might have an older version of xerces somewhere on your classpath with is conflicting with the version needed by alfresco. it seems like the DOMImplementation your classpath is providing does not have support for LS 3.0. can you provide some information on your server environment, particularly which version of xerces is part of your jvm distribution? check $JAVA_HOME/common/endorsed as well to see if you have a xerces.jar there.

thanks,

ariel

I've also tried with IE6 and Opera 9.1 and both give the same problem.

The only version of xerces on my classpath is the one bundled in the alfresco web app (xercesImpl-2.8.0.jar). I have just tried xercesImpl-2.9.0.jar and get the same problem.

Env details:

jdk 1.5.0_11
weblogic 9.2 MP!
SuSE Enterprise 9 SP2

Thanks,

Mike.

I turned on debugging for the org.alfresco.web.app.servlet.UploadFileServlet and get the following:

Re: Problems with the WCM preview tutorial

arielb — Wed, 07 Feb 2007 19:13:20 GMT

can you take a look at the jars within your jdk and weblogic and see if any of them contain xerces, and if they are clobbering the xerces version in the classpath? also, try copying xerces-2.9.0 into tomcat/common/endorsed, restart the webapp and see if that fixes things.

Re: Problems with the WCM preview tutorial

mike — Thu, 08 Feb 2007 08:40:01 GMT

I've doubled checked and I definiately have no other versions of xerces either in my classpath or contained in any jars.

I've added xerces-2.9.0 to the weblogic equivilent of tomcat/common/endorsed and still get the same problem.

The trace below shows it is now using the new version of xerces as one line has changed slightly (highlighted in bold)

Re: Problems with the WCM preview tutorial

arielb — Sun, 11 Feb 2007 01:39:44 GMT

i'm afraid i'm really not quite sure what's going on here - as i've never seen this and am unable to reproduce. if you have access to the source tree, could you add a debuggin statment to confirm that the problem is with this line:
final DOMImplementationRegistry registry = (DOMImplementationLS)registry.getDOMImplementation("XML 1.0 LS 3.0");

meaning, can you confirm that the result of that is null? if so - it is definitely something peculiar about your environment and i guess we'll have to set it up and try to reproduce it.

Re: Problems with the WCM preview tutorial

mike — Mon, 12 Feb 2007 11:40:41 GMT

Ok I've got the src and added some debugging.

You are correct thinking the result is null - I will continue trying to debug why this is the case.

Thanks,

Mike.

Re: Problems with the WCM preview tutorial

mike — Mon, 12 Feb 2007 13:30:58 GMT

Ok its working now

Removed my complete weblogic install and reinstalled with the basic setup and worked first time. The previous version had WebLogic Portal, AquaLogic Service Bus and the development/sample products also running. Therefore I assume there was some sort of conflict.

Thanks very much for all your help fixing this

Mike.

Re: Problems with the WCM preview tutorial

arielb — Mon, 12 Feb 2007 20:19:23 GMT

whew… that's a relief. i'm still really curious to know what the conflict might have been… i'll add some better error handling to that code path so in the future others don't spend quite so much time debugging it. thanks for your patience.

Re: Problems with the WCM preview tutorial

You say "self made" install - one the things in our tomcat install is that we add xalan.jar and serializer.jar to tomcat/common/endorsed. You might need to do the same.

Thanks,
