Please try the standalone java code attached (TestDocumentum.java) from the machine on which LiveCycle server is installed. If this works then we'll have to look into it and if this doesn't work then there is something wrong with your DFC client jars or documentum server.

Prerequisites:-

    1.) you should have jdk1.6 or higher installed on your machine. Set environment variables JAVA_HOME=c:\java\jdk1.6.0 and PATH=%PATH%;%JAVA_HOME%\bin

    2.) DFC for Documentum 6.7 SP1 should be installed on your machine.

Follow the below steps to run the file TestDocumentum.java:-

1.) Update the below lines in the file TestDocumentum.java according to your installation:

    private static String USERNAME = "sp_admin";

    private static String PASSWORD = "P@ssw0rd";

    private static String DOCBASE = "Docbase1";

2.) Run the below commands:-

    javac -classpath E:\Documentum\config;"E:\Program Files\Documentum\Shared\dfc.jar";. TestDocumentum.java

    java -classpath E:\Documentum\config;"E:\Program Files\Documentum\Shared\dfc.jar";. TestDocumentum

If you receive the same error "Could not initialize class com.documentum.fc.client.DfClient" then, most probably your client jars are corrupt. Otherwise please contact enterprise support.

Okay, that shows that you are able to create content in Document Server from java client. So, this narrows down the problem to LiveCycle only, this could also be a configuration issue.

Before you contact enterprise support, I would want you to double check that you have followed the LiveCycle documentation properly and have not missed any configuration and that you are on a supported platform.

Please make sure you have followed the steps in http://help.adobe.com/en_US/livecycle/10.0/InstallJBoss/WS1a95df6a070a c5e3533917eb12fb665b6bc-7fff.html . Documentum 6.7 SP1 cannot be configured using LCM currently. You will have to do it manually by adding appropriate jars in adobe-component-ext.properties file (in jboss/bin) and updating the settings in livecycle adminui, followed by a jboss restart.

The class path in adobe-component-ext.properties file should be in a single line.
