Within Identity Manager, SSH is handled by use of the JCraft classes, which are contained in jsch.jar. The Attachmate 3270 Mainframe Adapter for Sun includes a copy of the JCraft classes in RWebSDK.jar (Identity Manager does not actually use these classes for 3270 connection ). The two jars do not contain the same version of the JCraft classes, however, which may cause conflicts, depending on the order in which the jar files are loaded by the web container.
To avoid these conflicts, you should make a backup of RWebSDK.jar, and edit the RWebSDK.jar with an appropriate tool (such as WinZip), remove the com.jcraft classes, and save the file. This will eliminate the unwanted version of the JCraft classes, and SSH will function correctly.
RWebSDK.jar is not distributed with Identity Manager, and is only available as part of Attachmate 3270 Mainframe Adapter for Sun.
