From the exception, it looks like UCF hasn't been downloaded to Browser/Client machine. This will impact all content transfer operations (Import, Export, Check-out, Check-in etc.)

Can you please confirm the following details of Browser/Client machine:

OS version, 32-bit or 64-bit?
Browser version, 32-bit or 64-bit?
JRE version and 32-bit/64-bit, that is being used by browser?

Is it Webtop 6.7 GA or any Service packs or Patches applied? Exact Webtop version/build?

Above details will help to understand the issue clearly.

Hi Narayana,

OS version, 32-bit or 64-bit? Windows 7 SP1, 32 bit
Browser version, 32-bit or 64-bit? IE 9 (How to check 32 or 64?)
JRE version and 32-bit/64-bit, that is being used by browser? See Attached

Is it Webtop 6.7 GA or any Service packs or Patches applied? Server Version : 6.7.2060.0087 Linux.Oracle

Exact Webtop version/build?

Awaiting your reply..

Since your OS version is a 32-bit windows OS, there is no way you can install 64-bit IE browser or 64-bit JRE. All items are definetely 32-bit.

BTW, did you open any Consult Request or Service Request with EMC/Documentum Support?

I will see if there is any resolution/workaround for this issue and post it at the earliest.

Hi Narayana,

Thanks for reverting back. I havent opened any SR with EMC yet. Please check and let me know to solve this issue. I have tried clearing all the cache like IE, UCF and JRE. But still not sure why this error is occuring.

Hi Bharani,

Did you cross check if the UCF related files/libraries are being downloaded successfully to Browser machine for the first time? I doubt UCF hasn't been loaded to Browser m/c successfully and it will impact all the content transfer operations?

Since you have 2 JRE versions enabled in your machine, not sure which one is being used. First of all, check if your Webtop 6.7 supports the JRE versions that you have in browser machine.

You can also enable "Java console" from Control Panel -> Java (32-bit) -> Advanced tab with "enable tracing" and "enable logging" options and retry the import operation to see if there is any useful information.

Thanks,

Narayana
