servlet mapping

[gurneeraj singh]

In my application I placed a newEnquiry.jsp in enquiry directory of my project. Form in it is calling NewEnquiryServlet without any problem.

Jsp Code:

  <form action="newEnquiry" method="post">  [color=red]<---action[/color]
                <div id="companyDetails">
                    <div align="right">
                        <div id="markUp" class="compulsoryField" style="width:95px; height:12px; border:white groove 1px;">*Compulsory Fields</div>
                    </div>
                    <fieldset>
                        <legend>Details</legend>
                        <table border="0"   id="companyAddressTable">

                            <tr>

                                <td ><span class="helpMessage" id="companyNameHelp"></span></td>

project/enquiry/newEnquiry.jsp
project/enquiry/reconfirmation.jsp

WEB-INF/classes/com/inventa/enquiry/NewEnquiryServlet
WEB-INF/classes/com/inventa/enquiry/Reconfirmation

Kindly suggest me how to solve this issue when ever i click submit button in reconfirmation.jsp it automatically adds /enquiry/ url before servlet name but no so in case of newEnquiry.jsp and causing error to display.

How should i solve this problem

[Frank Eichfelder]

You are using relative paths in your JSP pages and servlets. I would suggest to use absolute paths (beginning with '/'), this should solve your problem.

[gurneeraj singh]

But if i use absolute path like /reconfirmation in my jsp it takes the page out of scope of apllication like;

http://localhost:80084/reconfirmation

instead of

http://localhost:8084/projectName/reconfirmation

[Frank Eichfelder]

That's true, therefore you should add

    
request.getContextPath();

to your servlet code and

  ${pageContext.request.contextPath}  

to your jsp-pages.

[gurneeraj singh]

Thanks Frank,

Your solution must solve my problem.

But now i am facing a strange problem, when ever i click a link for any jsp file or servlet, web browser starts downloading it instead displaying it on the browser.

What can be the error or my ide got currupted?
