I am getting the exact same error. I have tried installing Adobe Livecycle 8 on two separate machines and they both give the same problem. In viewing at the logs, it seems that the IBM CM jar files are not being recognized by the Adobe installation. For me, I get the following logs as well in addition to what you see.
Caused by: java.lang.NoClassDefFoundError: com.ibm.mm.sdk.common.DKDDO

The DKDDO class is in the jar files that are inside II4C installation folder. I think that the file
"adobe-component-ext.properties" that they ask us to create to reference the IBM CM jars is not being picked up by the Adobe Connectors for IBM CM. Do you see the " java.lang.NoClassDefFoundError" in your logs? Any resolutions you had regarding this.
I even tried to copy the ibm jars to various paths and copied the props files ad various different locations. I am under the impression that the documentation may not have been updated for this change.
Anyone tried using IBM Content Manager Connector from Adobe Livecycle forms server? I still can't get it working. It seems that the connector can not find my jar files that I have referenced in the properties file it asks to create.
