fact

Novell iManager 1.5

symptom

Error: System Error Could not find native libraries for com.novell.emframe.fw.NDSNamespaceAuthenticator

cause

This error is generated because Tomcat does not know how to find the jclient.jar or eMFrame.jar files. 

fix

This is usually resolved by making sure the java_home variable is set right and re-install iManager.  If a customer runs Tomcat in an unsupported way, this error can also occur.  Consider the following:

Tomcat 4.x was installed, instead of Tomcat 3.3:
Here is the issue..

When iManager installs Tomcat, it creates a Windows service for it to run under called Jakarta. The Jakarta service uses a file called wrapper.properties to define various properties and environment settings that it needs. These settings include the command line that the service uses to start Tomcat as a java application. One of the parameters passed into Tomcat on the command line at startup is a Java property called java.library.path which is set to $(wrapper.tomcat_home)\webapps\eMFrame\WEB-INF\bin. Tomcat uses this path to find native libraries including jclient.dll.

For Tomcat 4, Tomcat uses a window's installer which creates a Tomcat service. It uses a similar mechanism to tell Tomcat where to find native libraries. The -Djava.library.path argument to the command line it uses to launch Tomcat.   If a customer uses Tomcat 4, they are responsible for all configuration.  Tomcat 4 is not supported with iManager 1.5. 

Issue 2:
If you are not running Tomcat as a Windows service, you would need to modify the batch files that are used to start it to include the java.library.path.

On a NetWare 6 server only, look in the sys:\tomcat\33\bin\tomcat33.ncf file and verify that the 'envset TOMCAT_CLASSPATH=$TOMCAT_CLASSPATH;SYS:\java\lib\jclient.jar' line is at the end of the list of envset.  If it is not, add that line and restart Tomcat.
