I have a fresh install of Eclipse 3.1 M7 with the latest MyEclipse (3.8.4+QF2-BetaFor3.1M7) build ID 200505151200-3.8.4+QF2-BetaFor3.1M7. In every JSP I edit, no matter what, when I click on the Preview tab, I get an exception and also an unhandled event loop exception in the “Error Log” view. All of the data is below:

Session data:

java.version=1.5.0_01
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=en_US
Command-line arguments: -os win32 -ws win32 -arch x86

Severity: Error

There are quite a few API breaks in M7 that are occuring in our beta, also the preview and designer are going to be totally replaced for our 4.0 release, so for the time being just try to avoid the Preview tab.
