Enabling Documentum Composer features on Eclipse Europa

Filed under: documentum — Tags: , , , — Raj V @ 11:28 pm

I ran through an article to Install Documentum Composer on Webtools project. However I was having Eclipse Europa  3.3.2 installation and want to enable Documentum Composer features on it.
The same rules apply other than getting the suggested updates. Europa uses the Discovery of features available on Eclipse site.

This came out to be much easier without much configuration as the required EMF Validation framework was already part of Europa.

  • Install Eclipse Europa JEE edition from Eclipse Europa Site.
  • Unzip EMC Documentum Composer to a separate folder (or you can extract the com.emc.* packages into corresponding eclipse plugins/features folders)
  • Copy com.emc.* from Composer/plugins directories to Eclipse/plugins directory.
  • Copy com.emc.* from Composer/features directories to Eclipse/features directory.
  • Start Eclipse and your are ready with Documentum Project with JEE that you can use for WDK development.

Hope EMC releases a update site for Composer along with a complete build.
This will enable using the update site to install “Composer” over existing installations of  Eclipse Europa/Webtools.
This saves lots of RAM (a minimum of 300MB).

Previous installation I had was (Hungry for memory):

  1. DCTM server (6.0 SP1 bundled with Weblogic)
  2. Oracle 10g R2 (Pre SP1 I was on Oracle 10g XE as development docbase to save on memory. XE comes for free and with complete feature set a docbase requires and a small footprint)
  3. Tomcat Webtop + DA
  4. Eclipse for Documentum WDK Development
  5. EMC Documentum Composer for DocApp Builder/Installer

Now with new installation I could atleast live with one Eclipse installation with the  option of having WDK Development and Documentum Composer in one IDE.

Few features I would like to see in Composer to make it a unified Documentum Development Tool are :
IAPI/IDQL (features of Samson) ; WDK WYSIWYG Editor, DFS SOA Design time with HTTP Analyzer.

Configuring Eclipse for DFC projects

Filed under: dfc, documentum — Tags: , — Raj V @ 9:05 am


To setup a DFC development environment you will need at a minimum the dfc.jar and dfcbase.jar files. However, we recommend that you reference all the jar files in the folder that contains the dfc.jar file.
On Windows, this folder typically is c:\Program Files\Documentum\Shared.
In addition, you will need any classfolders and jars of your custom business objects. Another important component is the folder that contains the and the file. This folder needs to be in the classpath too.

Creating a Java project for DFC development in Eclipse 3.1


  1. Click on menu item File->New->Project
  2. From the ‘New Project’ window select Java->Java Project and then click on ‘Next’
  3. Enter a project name (example – ‘Simple DFC Project’). For sake of keeping things simple, keep the defaults for other options on this screen. Click on ‘Next’.
  4. Select the ‘Libraries’ Tab and click on the ‘Add External Jars’ button.
  5. In the ‘Jar Selection’ dialog navigate to the folder that contains the dfc.jar file. On Windows, this is typically c:\Program Files\Documentum\Shared . Select all (CTRL+A) the jars in this folder and then click on ‘Open’.Fig – Add DFC Jars
  6. Now, click on the ‘Add Class Folder’ button and then click on ‘Create New Folder’Fig – Add Class Folder
  7. In the ‘New Folder’ dialog give some name (e.g. ‘dmConfig’) and click on ‘Advanced’
  8. Select the ‘Link to folder in filesystem’ checkbox and choose the folder that contains the file. On Windows this is typically C:\Documentum\configFig – Link to the folder containing the file
  9. Click on ‘Ok’ in both the ‘New Folder’ and ‘Add Class Folder’ dialogs
  10. Again for the sake of simplicity, keep the default project settings and click on ‘Finish’.
  11. Eclipse will create a project with the default source and output folders. You can now create Java classes that use DFC in the project. To create a new class right-click on the source folder(or package) and select New->Class. To execute a Java class right-click on the class and select Run As->Java Application. For more details related to the Java development options, please refer to the Eclipse documentation.
