This issue applies to both Agent for IBM WebSphere Application Server 5.1.1 and Agent for IBM WebSphere Application Server 6.0.
The --install option of the agentadmin command can fail because of an issue with the IBM Java Development Kit (JDK). The IBM JDK comes with IBM WebSphere Application Server.
To run the --install option, the agentadmin script searches for a JDK with a Sun Microsystems JCE provider. However, the IBM JDK does not come with this JCE provider.
Therefore, to allow the agent installer to work with the IBM JDK, implement the steps described in the following workaround.
Workaround: The following task involving the editing of the agentadmin file makes available a JCE implementation that allows the agent installer to function properly.
