Unable to read content using Webservice

[mahkath]

Hi All,

When I'm trying to read the content using ContentUtils.getContentAsInputStream() API.

Intermittently I'm getting below exception(red & blue color) in Alfresco and the content is not read.

I'm getting exceptions in both Alfresco and in our Application server.
Exception in red color is thrown in our application server.
Exception in blue color is thrown in Alfresco server.

Can anyone have any idea why this exception happens?

Consider set authentication in advance.

mahkath have you solve it? I have the same problem…
If I login in the Alfresco Server with the same user-password that use my web-service-client and then do the logout, the method getContentAsInputStream works again… and my aplication provides the pdf files perfectly
This ocurs every morning… every night at 1.00am the Alfresco Server is shutdown to do backup works, so when I try to download a pdf file from my aplication the exception in the method getContentAsInputStream occurs
