We are getting errors while downloading a document using DFS. 6.6

We have a web application deployed on tomcat which consumes DFS web services to upload/download documents.

While downloading the document we are getting the following error.

com.emc.documentum.fs.rt.ucf.UcfException: Invalid checksum for file "ucf-ca-office-auto.jar".

Thanks for your response William.

I was able to figure out what exactly the problem was.Here is what i did to correct the error.

I pointed back to DFS 6.6 from 6.7 in my application.

Deployed a DFS.ear 6.6 on the server.Restarted it.

I recreated my war after deleting all the jar files from my /lib folder(excluding plugins,security&commons.jar).

Went to control panel and cleared the cache from JAVA option.

REstarted Tomcat and i was gud to go.

Regards

The error indicates the downloaded ucf-installer.jar and ucf-ca-office-auto.jar were not from the same build or had been modified.

In development environment, you can simply set dfs-runtime.properties: require.signed.jars = false to disable signature verification. In production environment, you need to use the consistent UCF library bundled with the same version of DFS ear or SDK.
