After applying NW65SP6 or an update to JAVA in novpatch3864, the following error is received when logging into iManager. " Unable to create AdminNamespace. java.lang.NoClassDefFoundError "
The following errors can also be seen in the logger screen.
NDSNamespaceImpl...4803 Unable to determine treename for wdfw (java.lang.Exception: Unable to initialize JClient: java.lang.VerifyError: Incompatible JClient/DClient package JClient Revision: 1.5.1107 DClient Revision: 1.3.1184)

1. Get The JCLIENT.JAR (6/27/2003) file from NW65SP6. The JCLIENT.JAR file is zipped up in the JCLIENT.ZIP file inside NW65SP6.
2. Copy the JCLIENT.JAR (6/27/2003) file to the SYS:\JAVA\LIB directory.
3. Unload JAVA, Load JAVA
4. Restart Tomcat. TC4STOP then TOMCAT4
5. Wait for Tomcat to finish loading (INFO: JK2: ajp13 listening on / in the logger screen), then you should be able to login to iManager.

Additional Information

iManager 2.6 SP3 is a platform independent patch. As such it is laying down a newer JCLIENT.JAR (3/10/2006) file in the ...\nps\WEB-INF\lib directory which is used on some platforms. However, this may not be compatible with the java dclient the OES (including NetWare) server is using. However, this should not be causing a problem on NetWare because iManager should be using the JCLIENT.JAR file in your SYS:\JAVA\LIB directory by default. If that file is missing, it will generate the incompatibility error. The correct version of JCLIENT.JAR should be layed down by NW65SP6 during the patch install.
iManager 2.6 SP3 includes the update to JCLIENT.JAR because iManager running on NON-OES servers do use the JCLIENT.JAR file in the ...\nps\WEB-INF\lib directory.
