Operations not successful(Export,Checkout) by DFC code

Hi,

I was facing a strange issue in DCTM 5.2.5.
When I tried to export a document by a DFC code, code is running fine without any errors, but at last it's not getting exported.
I have checked all the options, but they were useless.
Than I tried to export it manually, and found that it's getting exported.
The same thing happens, when I tried to checkout a document.

Than after investigation, I found that when I tried to execute Export or Checkout manually, it gives a pop-up java applet every time to click Yes. Once I set it to remember all the time, the operations are getting easily executed.

com.documentum.ucf.common.UCFException

Error:
I am getting the error - com.documentum.ucf.common.UCFException, while tried to export the file from DA6.5
***************************************************************
Failed to retrieve content from ACS/BOCS server(s). The ACS/BOCS server(s) may be down or your machine may not be able to reach the server(s) due to network connectivity or configuration issues com.documentum.ucf.common.UCFException: All remote hosts failed
****************************************************************
Resolution:
ACS is a servlet on the Java Method Server and it is down. So check the Tomcat logs. If you don't use this then I would suggest disabling it.
TO disable - modify the setting app.xml in webtop:
As per my DA installtion on local, File path: C:\apache-tomcat-6.0.18\webapps\da\wdk
Please disable it in both - accelerated-read & accelerated-write, by modifing the tag enabled to false.

Resolution:
I have successfully called the method with slight correction of export format -

You can get more details format's name for each file type by -
Documentum Administrator -> Formats

It displays the format's name and description. The DOS extension is not showed, but you can see it on it's Info page.
Or you run a query like this:
SELECT name, dos_extension FROM dm_format WHERE dos_extension='docx'
