[Pault]

Here is strack trace of what I am getting .... saying setseed not supported.
Any ideas how to resolve this issue, any help greatly appreciated.

[coz]

When Tomcat starts up, it attempts to construct an instance of java.security.SecureRandom, which contains an implementation of the java.security.SecureRandomSpi interface, fulfilled by a provider in java.security. On your system, the provider appears to be the ICSF. (Check in <JAVA_HOME>/lib/security/java.security and see if you have a line like this):

Code: Select all

security.provider.1=com.ibm.crypto.hdwrCCA.provider.IBMJCECCA

As part of its random initialization, Tomcat sends the setSeed() message to the SecureRandom instance to set an initial seed.

IBM's implementation of SecureRandomSpi doesn't support seed setting, so it throws an UnsupportedOperationException.

Tomcat is catching this exception and issuing the message and stack trace that you see, but should be falling back on an instance of java.util.Random. I assume that it is starting up OK?

What's really at question here is who should be doing things differently: The interface (java.security.SecureRandomSpi) says nothing about the methods being optional, so perhaps IBM should have implemented a null method body rather than throwing an exception. Alternatively Apache (Tomcat) could explicitly look for and ignore the UnsupportedOperationException. In any case, the message you're getting is probably a little over the top. You might try writing a bug against Tomcat or IBM to clear this up.

In the meantime if the message is bothering you, you can remove the ICSF provider from java.security so that the hardware facility is not used.
