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
