How to convert a .class file into .java file without .jad using DeJDecompil

Hi all,
I am using DeJDecompiler and working with swing applications.If I try to convert a .class file into .java file,it is converting into .jad file only.Fine but if I try to save that file into .java file,It is giving lot of errors in that program.When I went into that program the total style of the program is changed and TRY-CATCH block is not recognised by the dejdecompiler,hence If I try to include some methods in the existing .java file thus got,I could not do.Kindly help me.
If I get the .java file without error then I can process the rest of the functionality.
Thanks in advance
With kind Regs
