Hi Suzana,
This is the sort of error you get when the LAS just doesn't know how else to tell you something is wrong in your configuration. When I get this sort of error it's usually in the xml somewhere. If I were you, I'd back off on the customizations and start applying them one by one until you figure out which one is causing the error - then write back to the user group to see what is wrong with the particular customization you're trying to apply.

Hi all,

I'm forwarding Suzana's request for assistance as I'm swamped with other itmes at the moment. If anyone can help I'd greatly appreciate it. If not, I'll get to it next week.

Hello Jonathan,

Excuse my bypassing the LAS user's forum, but from what I can see you're
in charge of answering this type of questions, so I figured might as well
go to the source directly.

We have just installed LAS 6.2.1 and have recently run into an error I'm
having a hard time figuring out. Trying to get to the default page
at http://aigeann.ucsc.edu:8080/las621/servlets/dataset
gives the error listed below. We have made some customizations to both the
dataset and visualization output options, but I can't make heads nor tails
out of this error listing to know where to start debugging.

Could you please take a second and see if you can give me a hint as to
where to start looking ? Any help would be appreciated...

Thanks ahead and best regards,
