Activiti Explorer Failing from logging in

[sid121091]

Hi,

I am new to this, and I apologise in advance if I am not presenting my problem correctly.

Every time I log in to my local activiti explorer, or access anything in it or even try to deploy something, I get the error "Error Parsing XML" along with the following error log. I have searched through the entire forum but am unable to identify the right solution for my specific issue. I request you to help me at the earliest.

[setu_poddar]

we are deploying activiti on specific of machine and getting this error. It has become a big road blocker. 
It looks like system specific issue, please help with it

[jbarrez]

The error seems to indicate it happens when parsing XML. On what kind of server are you deploying this? This could interfere with the xml parsing …

Also: are all characters in  the XML UTF8? You mention locale … what locale do you use?
