We have been using the Oracle deployment rule set with Java 7u51 and 7u38 and it has been working good managing legacy versions (using static installs) of Java 6 with Java 7. When we upgraded clients to Java 7u55 our DRS rule stopped functioning and the error "Deployment rule set required java 1.6.0_38 not available". So we are having same issues you are and the only change has been 7u55. I did post a bug report but haven't heard back.
One part here catches my eye: DeploymentRuleSet.jar is signed with a certificate from an internal CA.
Technically that is not supported, but it will work assuming you have added the internal CA to your installations. My first guess would be that this assumption is not valid, meaning the CA is missing from the newer version.
This can be quickly checked by:
C:\program files\java\VERSION\bin\jarsigner -verify DeploymentRuleSet.jar
If one of those says that the JAR is invalid, then it would prove that the internal CA was missing.
costlow - I disagree. If I'm using IE, then I only need the internal certficate used to sign the jar to be also insalled on the machine in question in the windows CA Certs store. If the cert was the issue, why does it work with 7u51. If it was a bad cert, it should fail with every version. Plus, I think the pop up has a different error message if it has a cert issue.
I'm having the exact same issue as the OP described and it all started with 7u55. Here's what I've found:
- With 7u55 or 7u60 installed, the error will come up rergardless of what prior version is being requested.
- If 7u51 is the latest installed, it works
- If 8u05 is installed with 7u55 and/or 7u60, it works
- If I install the 7u60 EA b15, it works
Something in the final release is being added that blocks this functionality, but for some odd reason only in the 7 family starting with 7u55.
Any insight you could give would be very helpful. In the meantime, I am deploying 8u05 to cover this up, but it does pose issues for some apps that don't work with the new 8 family plugin.
