Does latest trunk require Java 1.6?

[Vince Clark]

Surely this is not the case. But I am trying to start OfBiz using 1.5 and getting the following:

2008-08-07 16:37:22,529 (main) [ GenericDelegator.java:217:INFO ] Delegator "default" initializing helper "localpostgres" for entity group "org.ofbiz".
2008-08-07 16:37:22,538 (main) [ GenericDelegator.java:234:INFO ] Doing database check as requested in entityengine.xml with addMissing=true
Exception in thread "main" java.lang.UnsupportedClassVersionError: Bad version number in .class file
at java.lang.ClassLoader.defineClass1(Native Method)
at java.lang.ClassLoader.defineClass(ClassLoader.java:620)
at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:124)


I was running Java 6 on Ubuntu but it was causing Eclipse fits and crashing all the time. So I removed Java 6 and reinstalled 5. Now I can't get OfBiz to start. I can build with no errors, but when I try to start it gives me the above error.

do you have the correct postgresql jar in the framework\entity\lib\jdbc

sorry did not see the bottom
did you do a
ant clean
and
then
ant run-install

yes I did ant clean. Even downloaded a new checkout from trunk after getting rid of Java 6.

I think the postgres jar file is the more likely culprit. But I don't recall downloading a postgres jar file specific to Java 6. Going to look at postgres downloads now.

I don't see anything on Postgres jdbc downloads that would make any difference. The latest driver just says it requires Java 1.4 or later.

You could have extra class files cached from previous runs. Certainly
doesn't look like a postgres jar file problem specifically.

Catalina is the favourite for temporary class files so possibly try this
first:
  ant clean-catalina
and if you browse through the build.xml file you'll find a few others
that get run when using:
  ant clean-all
Be WARNED though "clean-all" is a little more aggressive in that it
clears the derby database folder along with lots of other runtime files.
Really puts you back to a clean checkout so make sure you've got your
data backed up if required, although it won't delete your postgres data :-)

I confirm it runs here with Sun jdk 1.5 (On Windows XpSp2 ands Ubuntu 8.04 LTW)

I went back and looked at the postgres driver again and sure enough there is a difference. I was using a driver labeled JDBC4, which only works with jdk 1.6. I switched back to a jdbc3 driver and jdk 1.5 is working now.
