I give version information about JDK in Jennifer Server and JRE in JENNIFER Client.
1. In case of JENNIFER Client(Browser), it supports sun jdk 1.6 and (and ms-jvm).
In case of sun jdk, max value of heap memory is 64mb. If you have some problem in daliy data search in X-View graph, it might be OutOfMemory. Increase the max value of sun jvm or use.(ms-jvm does not limit Heap memory.)
Refer to the client configuration chapter in JENNIFER User’s Manual about setting instruction.
2. In case of JENNIFER Server, it supports from JDK1.4 to 1.6 version.
