understanding the java code

Hi all i am new to this foru n this is my first topic,

we use erp tool kits to design portals for colleges and schools. this erp toolkit generates the java code in making this portal. so we dont have to do anything with java.

But i would like to dig aroung through this code generated by erp tool kit. i found the folder and the folder has many sub folders like web-inf, meta-inf, and many classes.

Q: As i'm not a professional in java but has some adequate knowledge can any one help me where should i start decompiling the code? help me

First, tools generated code are generally horrible -- Not documented (or only generically documented). Does stuff that doesn't make sense. etc.

Second, decompiled code are generally horrible -- May not be valid Java (decompile failure). No comments. May have incorrectly named variable and method names.

Now, you want to decompile tools generated class files?
