I Use Tomcat 4.0.2 and Struts 1.0.2 with VA 3.5.3
Everything was perfect until, one inauspicious moment in the afternoon when I suddenly
got this exception from nowhere.
I have no clue as to why and how. But I do see that this is a ClassFormatException so,
I moved the application related code (not struts) onto another machine where I
previously deployed my app. The app was fine on this box earlier.Now, I get the same
ClassFormatError there too so, It has to do with the code I moved.
The Java API says that it is "Thrown when the Java Virtual Machine attempts to read a
class file and determines that the file is malformed or otherwise cannot be
interpreted as a class file. "
So .class file is corrupt/malformed. But which? I am trying to force a recompile on
classes by adding a space, etc.
any ideas on what sould be done next if my attempt fails?
here is the exception....
Thank You for your time
