Thread: Problem with the LargeObjectManager class in 7.2.1 java libraries?

I’m trying to compile and build some java source code on a Windows XP Professional system.

The IDE I am using is NetBeans 3.4.1 and j2se 1.4.1_02 from Sun.  I have the pg72jdbc2.jar file in my class path for my IDE.

The source file compiles without any complaints but when I try to run it I get :

‘ java.lang.NoClassDefFoundError: org/postgresql/largeobject/LargeObjectManager Exception in thread "main" ’

I am only including a pertinent code segment since the source file is rather lengthy.

Any ideas?  I was thinking that since I do not get any complaints until runtime that I might not have path variable  set properly.

Thanks,

-Bill Thomason
