Xpages can't load, Error 500; java.util cannot be resolved

Question

I recently moved a couple of applications to a server that is running Domino 9.0.1FP8 (JVM version: JRE 1.8.0 Windows Server 2008 R2 amd64-64). Since I did this I\'ve been u

Answer 1

It sounds like the installer has not installed successfully. There's no reason java.util packages should be failing. I would recommend running the installer again, making sure all services are stopped prior to running it. That will ensure that anything that needs replacing isn't locked by another process.

Answer 2

This problem occurs when Domino Designer 9.0.1 FP8 attempts to compile against a Java8 JRE. The version of eclipse in that Designer install does not know how to parse some of the runtime jar files in Java8. The workaround is to compile against a Java6 JRE instead. There were changes in the Domino Designer installation as part of SPR#BGLN9PXEVM to change the configuration of the preferences in Designer to point to a Java6 JRE instead of using the default JRE. If there was some install problem or you manually modified your preferences, you may need to manually re-apply the workaround as follows.

In Domino Designer, menu File, Preferences, Java, Installed JREs. There should be 2 listed JVMs with paths like so:

• [x] jvm C:\Notes\jvm1.6\
• [ ] Notes 8.5.1 VM (locked) C:\Notes\jvm

If your entry named "jvm" is incorrectly pointing to the C:\Notes\jvm\ folder instead of the jvm1.6 folder, then you will need to edit it to point to the jvm1.6 folder instead.

On the Domino Designer team we are investigating potentially upgrading the eclipse version in Designer, so that it might be possible to compile against a Java8 JRE.
