Which CPU architecture is this? We observed some issues with AMD processors. We typically test on SPARC64bit and Intel64bit.

Can you try to get the tomcat-bundled alfresco?

Looking at the source, it looks like it's failing while trying to resolve resource bundles. Which language are you using?

This is really weird, things seems to be working now.
I restarted Tomcat and I noticed that I was able to access the site through localhost but not from a remote computer. After some time period I am now able to access the site through the remote computer as well.

I don't know what could have changed but is it possible it was taking a while to load up resources or something?

I am running the site in US English language. I should note that this is currently set up in a VMWare VM Server.

OK, so I might be getting to the bottom of this issue. It seems that where I start Tomcat from has some affect on if the app comes up successfully. I dont know if it has something to do with the classpath getting messed up. It really shouldn't as I am using the standard start/stop scripts that come with Tomcat.

I just did another install on a 32 bit Fedora Core 8 machine I had kicking around with Tomcat 5.5.9 and I have not had any problems at all yet.

I am wondering also if the fact that it was running on a VM could be an issue. I recall seeing at some point that the VM may be emulating AMD 64 bit architecture. Can anyone confirm this?

Anyway, I'll play around on this new working copy as I want to test the Alfresco functionality not the Fedora Core infrastructure…yet.

Thanks

That could be the case if you are using the relative path for your file store. By default, it writes the file store to .\alf_data, so if you change the present directory, it looks to the file store in different places.

This is why there is a warning saying to change it to an absolute path.

So please point dir.root to an absolute path and this might go away for good. Blow away your db first though (if you are using MySQL).

Hi Mike,

We just came across this problem ourselves on Alfresco Enterprise 2.2. I might be wrong, but it seems like the ResourceBundleWrapper object is being persisted with the user session by Tomcat. When the session is restored, the list of resource bundles held by the class is empty (null). Hence the null pointer exception.

You may have noticed that since 2.2, the class now implements Serializable. I believe that was added to support Tomcat clusters.

Anyway, the (not very elegant) solution we found was to delete the Tomcat work/Catalina directory on each restart.

Does anyone have a better solution?

Regards,
Frank
