Trouble getting folder by path in DFC

Asif2012

Hello, folks:

I am new to this forum. At a Federal agency in Washington DC, where I work, we are trying to import bulk PDF documents in Documentum through a Java program that I wrote. The Java program is mainly a sample that I downloaded from here.

Documentum 6.7

Windows Server 8

JRE 1.6.0_27

While my program is able to get various info about the target repository, it cannot find the target folder. I am using the same folder as it appears when I log into Documentum WebTop. I would greatly appreciate your help. Here is the working source code:

My program is throwing exception here (in the above code):

if( folder == null ) {                LOGGER.error( "Could not obtain path to the target folder: " + TARGET_FOLDER );                throw new Exception( "Could not obtain path to the target folder: " +                         TARGET_FOLDER );            }

Thanks in advance.

Hi,

I think you just need to add a forward slash ("/") in front of your folder path.

In your example if "IDA" is the root cabinet you should use something like this:

private static final String TARGET_FOLDER = "/IDA/NAPA";

Thank you so very much, Frederic. I fixed the folder, and now it works. I wish I posted this question 3 days ago. But I so glad that you came over to answer. Thanks again.

I got another question, and would greatly appreciate any help.

In the above code, as I wrote it, the program first imports two documents to Documentum, then gets them back from the open session, and finally allows you to set attributes on each document (I have those lines commented out). Does the DFC API provide a way to set attributes on a document and then import it? I just looked at DFC API 7.0, but cannot find any suitable method there.

I just heard from a team member, who administers Documentum. He suspects that WebTop went down because my above program imported 2 documents without setting required attributes on them. So he suggests that I import a document along with its required attributes at least. I am curious about this situation. Is there a way I can set attributes on a document before importing it? Thanks in advance.

hi Asif,

you can use IDfDocument.setString() and there are other methods for adding the repeating properties also.

If your requirement is on Import ,if you want to set the attributes then try for using a TBO ( BOF) so that every time on import of a document your attributes getset.

Cheers..

Asif2012

Thanks for response. As you can see in the code in my original post, I can set attributes on IDfDocument only after I have imported this document. I want to set attributes on this document before I import it. Could you please post a code example of using TBO (BOF)? I would greatly appreciate it. Thanks.

HI Asif,

Kindly find the example over here

Asif2012

I looked at the example code. Looks interesting, but I have not tried them yet. For now my program is working just fine and imported over 33,000 documents in Documentum in about 90 minutes. No issue so far. But I will definitely use the examples that you pointed to. Thanks again.
