I would be really happy if anyone gives me an idea about what the 3 mentioned below errors mean and more importantly in what situations excatly do they arise.
1. IncompatibleClassChangeError.
2. LinkageError
3. NoClassDefFoundError.
I was working on servlets and my servlet code in doPost() method contained references to lot of getParameter requests to hidden elements of Javascript(it was nearly around 450).If i tried to acess all of the variables it is giving IncompatibleClassChangeError.If some of them were removed its not giving any error even though there's nothing wrong with variable names i was reffering to. I could not figure out the exact reason for occurance of such an error(InCompatibleClassChangeError). I anybody can help me i would be really happy. Also please do mention the resaons for occurance of the other two mentioned errors.
