Can you give more detail when you are seeing this start-up message? Are you working on Community or Enterprise? Also, what server platform are you on?

It prevents the Virtual tomcat from previewing content. I have got this on my XP laptop and a Windows 2003 Server. Initially the Virtual tomcat on both worked…now it doesnt. The only things I have done have been to create new web projects/forms and delete them.

thanks,
Alex

I'm seeing this too on a development machine. It's running Alf v2.0.0 Enterprise.

org.alfresco.catalina.host.AVMHostConfig$AVMWebappDescriptor.setParentRepo()‍

is NullPointerExceptioning as soon as the Virtualization server starts.

I may blow away my repository to see if it clears up, but it seems that someone should address this. Example of addressing this: what could cause AVMWebappDescriptor.setParentRepo() to throw such an exception? What if webapp_descriptors is somehow empty? Etc. etc.

Some developers in our team are seeing this problem as well. The Alfresco Virtualization Server used to start up just fine but all of a sudden it has stopped working and gives this error message.

Any help greatly appreciated.

Also if there is a temporary workaround we would very much like to hear as well.

P.S. we are running Alfresco WCM Community Edition 2.0.0 on Windows XP with a MySQL database.

cheers,

Edgar

The problem occurs in the following method of the AVMHostConfig class:


void setParentRepo(
                HashMap<String, AVMWebappDescriptor> webapp_descriptors,
                String                               parent_store_name)
        {
            parent_store_name_ = parent_store_name; 

            AVMWebappDescriptor parent_desc =
                webapp_descriptors.get( getParentContextPath() );

            parent_desc.addDependentWebappDescriptor( this );
        }‍‍‍‍‍‍‍‍‍‍‍‍

Line 2038 is the parent_desc.addDependentWebappDescriptor( this ) line so it would seem that the parent_desc is null.

However: this code excerpt is from the HEAD of the Subversion tree (today) and I do not know if this is the same code as in Alfresco Community 2.0.0. I cannot find any labels in the Alfresco svn repository..

But it would seem that getParentContextPath() returns null, causing the NullPointerException. It not quite clear to me why this should be so, or what the method in question is supposed to do exactly.

I searched in http://issues.alfresco.com but I did not find any issues related to the AVMHostConfig class so I don't think it is added as an issue yet. I will do so today.

Edgar

I have created the following bug report in Alfresco's JIRA system:
http://issues.alfresco.com/browse/WCM-434

Let's wait and see what the Alfresco engineers have to say.

If you changed the admin password in the Alfresco webapp, then you must also
change it in $VIRTUAL_TOMCAT_HOME/conf/alfresco-virtserver.properties

See:
# Admin level user and password to connect to login to Alfresco server.
#
alfresco.server.user=…
alfresco.server.password=…

If the virt server started fine, but then halted after displaying
pages successfully for a while, that's a different issue from
failing to start up;   the installer on windows should not be
running the virt server as a console app – it should be
installing it as a windows service (otherwise the process
eventually blocks).

– it should be installing it as a windows service

Sorry for being incredibly dense here… How am I supposed to install as a windows service?

I see no switch in the installer that allows this. And there are no services that identify themselves in the Services MMC as Tomcat, Alfresco, Virtual Server, or anything else vaugely familiar.

As for what I using:

Win 2K3 (virgin install)
Alfresco 2.0 Community Edition (Installer)
Alfresco WCM 2.0 Community Edition (Installer)

Ok, so a more thorough search of the forum turned this up…

Hey, I was finally able to get this to happen on a local machine,
and was able to track the problem down & fix it.

See: http://issues.alfresco.com/browse/WCM-434

If you want to try out *just* this fix & don't want to wait for 2.1, you can grab a nightly, and toss
$VIRTUAL_TOMCAT_HOME/server/lib/alfresco-catalina-virtual.jar into a 2.0.x distribution.
Restart the virt server, and you're all set (no need to restart the alfresco webapp).

Thanks again to those who gave me their debug log files.

If for some reason you cannot upgrade to r5648 or better,
you could do the following:

        [0] Turn off the virt server.

        [1] Mount the AVM via cifs

        [2] Look at <storename>:/www/avm_webapps/*
             for each store corresponding to an author
             (e.g.: mysite–alice:/www/avm_webapps/*

        [3] Via cifs, delete any webapp dir/file that isn't also in staging.
              When you do this, be sure to list every file,
              including hidden files. If you're on windows, I prefer to
              use a cygwin shell and do an "ls -laF"

        [4] When doing a bulk import prior to r5648, do it
              in staging not an author area.

        [5] Now that everything within your author stores at the
              /www/avm_webapps/* level is seen via transparency,
             your virt server should be able to start again.

Again, the best approach is to upgrade to >= r5648,
so this workaround only applies to those who cannot.

I hope this helps,
-Jon
