JSP import problem

[ashsa]

Hi,

I am using this statement exactly in my JSP page.

<%@ page import="java.util.*, java.lang.*" %>

But when i view the equivalent servlet generated, it is like this :

import java.util.*; //[ /hrms/budgetsAndCosts_HRMS.jsp; Line: 1]
import java.lang.*; //[ /hrms/budgetsAndCosts_HRMS.jsp; Line: 1]

And the second import is always getting to the end of the first import statement so that it is also included as a part of the single line comment '//'. This happens with all the JSP imports.

Could anyone figure out where the problem lies ... Its really urgent.

Many Thanks for any help .

Are you getting an error then?

The second import statement gets to the end of the first one like

import java.util.*; //[ /hrms/budgetsAndCosts_HRMS.jsp; Line: 1]#import java.lang.*; //[ /hrms/budgetsAndCosts_HRMS.jsp; Line: 1]

so that the second one is always commented along with the comment of the first import statement with a special character (shown as a square in my editor)
inserted at the place where you see '#' here. Thus only the class being imported first is being imported and it raises an error when there is a reference to the classes imported second or later .


Hope thats clearer ..

Do you get an error when you run your JSP?

If this is the import statement in the JSP page,

<%@ import="java.util.Date,java.util.Calendar" %>

the servlet generated shows it like

import java.util.Date; //[ test.jsp; Line: 1]import java.util.Vector; //[ test.jsp; Line: 1]

So, only Date is imported and not the Vector.
The second import is commented after

import java.util.Date;

as

//[ test.jsp; Line: 1]import java.util.Vector; //[ test.jsp; Line: 1]

Do you get an error when you run your JSP?

I get the error when am referring to the class which comes in the second import statement. Since the second import is commented along with the first import's sidenote, its not imported at all..

Thanks for any Help

Which error did you get specifically?

[dmjpro]

why did not u tell the particualr problem before?????

it does not happen to me.
i m using Oracle Jdeveloper for JSP Editor.
what r u using????

if this happens to u then change it into one packege import instead of more that one packge or class import.

one more thing i want to mention that directly come to the point.... instead of complicating the problem..
and i hope u ll not do that again.
have a good day.

I suspect it's just an editor problem; my guess is that those lines are just
terminated by a newline '\n' character and your editor chokes on it. If your
JSP runs fine I am right; if it doesn't there's a nasty bug somewhere in your
JSP compiler.

My JSP is more than rusty. Is it allowed to import more than one package
using a comma as a package name separator? Can you import those packages
using separate import statements, one of each package? Does it run then?

kind regards,

Jos

Very sorry for not being clear ..
After some hours of head break on it found that the error has been due to a missing new keyword somewhere .. Now thats working fine ...


And Thanks a lot your valuable concern.. Am using Editplus trial version and it shows the newline characters as unidentified chars..

Your suspicion about my editor is cent percent correct. My editplus trial version shows newlines as squares.. atleast that it shows !!

Regarding the import statement, its always valid to import more than one package using a comma as a package name separator. And as i understand theres hardly any difference between importing watever u want through a single import and importing one through each statement.

Many Thanks for the support ..

Ok, so we skip the editor for now as a cause (download vim instead!). Do your
JSPs work when you use separate import statements, one for each package?
(note that you never need to import java.lang.*, i.e. it's "self-imported" by javac).

If separate import statements do work, you're most probably facing a bug in
the JSP compiler. Which one are you using and what version?
