help me with my compiling jsp files

i got difficulty in compiling my jsp files. comiling jsp files is really a troublesome and a hard thing. html codes,javascritp codes and jsp codes all in one page. it's hard for me to find where the errors are.And more worse,i should finish my compiling job in the next two days to meet the deadline.but i still have five jsp files to compile.i wish someone could do me a favor to give me some suggestion on compiling more efficiently.Or somebody would take a look at my jsp code.i will apreciate your help. thank you

Plz send ur jsp code

why not try Jbuilder6? It is so swift in compiling a jsp file!

Thank you for responding.i got errors like this:
/comfirm.jsp:42:
pageContext.write(_jsp_string4, 0, _jsp_string4.length);
^
i use resin.what puzzled me is that i didin't use pageContext.write() method.i guess mage the
<%=....%>equals to this method. i don't know.

plz send the jsp , otherwise it may be difficult to help

this is one of my jsp files
i use it to check the form which contains
users' login or registering information.
i use parameter type in http-head to identify the
different kind of information.
thank you for your help.

I find that u have declared methods within scriptlets which can't be done u can declare methods only within declaration part.. Declarations begin with <%!. Use <%! before any method declaration...I can see typos also.. u have given Boolean is return type when u have returned boolean from the method ..correct the return type to boolean

thank you,i have neglect that declaration must be
start with <!.. and Boolean should be boolean.
however,after i had corrected the error,i still get the same error.
may be i should make a bean to contain all the methods in the jsp page.

I found 50 opening braces in your code but only 46 closing braces. That leads to the error.
