Hello,
I have been getting a NoClassDefFoundError exception when I ran BIRT inside
Eclipse. I saw the similar newsgroup posts earlier about the issue. This
exception is not occurring consistently. I used ODA to develop my custom
data source and data set, and this exception occurs while previewing the
report or previewing the results in the data set. It is caused when a class
in my ResultSet method calls my classes in other plugins. I know these
classes exist, and they are called fine by BIRT or other plugins, when this
exception doesn't occur. So, is it possible that BIRT is damaging the plugin
dependencies? For your information, I am attaching the exception:

Can you please log a bugzilla entry for this.
I have seen a similar issue when order of plugins being
loaded mattered. So if my ODA ran first it would work,
but if another plugin that used shared plugins ran first then
my plugin would fail. This was due to a class loader issue and
the plugin being in twice I believe. One other thing to try is
to set
setThreadContextClassLoader="false"
To true in the ODA runtime plugin.

fix though, but I will look more into that.
Thanks!
