Error message when I execute my page

Question

Hello,
I created a JSP file which must be published as a portlet....
I compiled it and take it to PortalAS machine...
I configured the provider.xml, I created a provider.xml file...
But when I execute my created page, the error message is being displayed:
"The following error occurred when attempting to call the initSession of the Web Provider: Carla4s 1 Provider
ORA-29532: Java call terminated by uncaught Java exception: java.io.IOException: Start of root element expected.13 : XML-0108: (Fatal Error) Start of root element expected. "
Someone had already this problem?
I created my provider using Login Frequency as Once Per User Session. If I change this option to Never, the error message is not displayed, but nothing is happening. My jsp page is not being displayed.
Thanks.
