java.lang.NoClassDefFoundError does not necessarily mean
was not found by the classloader. It may also mean thatthe class
failed during initialization. That's the more likely issueas you
haven't changed classpath or methods of loading and youare still
running in JVM 1.4.2.class
Find your standard out log and look for errors during
initialization much earlier than yourNoClassDefFoundError.

Start by checking how that java program is invoked. At
java.version system property has the most impact on
JVM isthe
chosen. That property can be set in the QSH java commandline (in QSH
java -Djava.version=1.4, eg).
In qsh, I can do this:
$
java -version -Djava.version=1.3.1java version "1.3.1"
$
java -version -Djava.version=1.4.2java version "1.4.2"
$
java -version -Djava.version=1.4java version "1.4.2"
$
java -version -Djava.version=1.1Java Development Kit could not be found.
$
java -version -Djava.version=1.2java version "1.2.2"
$
I haven't been able to find a way to set version from
RUNJVA....+....1....+....2....+....3....+....4....+....5....+..
command, however. I believe the command invocation pullsits value
from SystemDefault.properties file.
Browse : /qibm/UserData/Java400/SystemDefault.properties
Record : 1 of 2 by 18
Control :
There************Beginning of data**************
java.home=/QIBM/ProdData/Java400/jdk14/

As above, there's one in the /qibm/UserData/Java400.

one in the home directory of the user which takesprecedence over the
one in /QIBM.
There was significant displacement of classes in Java 5.
Many classes were added to the core distribution that
beenparticularly
commonly included only by classpath. This was
true ofthat
servlet classes. The net effect was that applications
had beenproperty
running in 1.4.2 would throw exactly the error you'reseeing as the
classes in the classpath were duplicated in the runtime.as possible
To see what you're command is doing, try to get as close
to the environment where RUNJVA is invoked in yourapplication and run
RUNJVA *version
If it comes up 1.5, you'll have to find where the
is set and[mailto:java400-l-
change it, else figure out what classes are beingduplicated in the
classpath and remove the jar from the classpath.

I want to start out by saving my java skills are

I have a java program that has been running fine for

Last week we installed java 1.5 (via PTF). I do not

No other changes I know of have been made. The java
changed in years and has not been recompiled.
But.. When I run the java program I get an error:

Does anyone have any starting point for me to look at?
