Subject Fw: Servlet problem
Date Mon, 20 Feb 2006 22:19:14 GMT
EDIT: I've sent this twice because the first one contained an error in what I wrote.  Ignore
the first one.

Hi all,

Apologies for the stupidity of this email but I'm having a few servlet problems.  I've created
the following SearchServlet.java file, compiled it into a class file using Netbeans then copied
the class file into my WEB-XML/classes file.  

Now for testing the servlet is very limited but when I try to run the jsp page the page is
redirected to http://localhost:8080/WEB-INF/classes/SearchServlet?itemvalue=type+search+criteria+here
and not /searchnone.jsp as specified.  When it's redirected to the first page though all I
get is my error.jsp page which is set up to catch 404 error pages as defined in my web.xml
page.  So it isn't finding something, what I don't know though.

Can anyone tell me where I'm going wrong?

Mark

searchitem.jsp:

<table width="100%"> 
<tr>
<td>
 <p class="subhead">Item Search Page</p>
 <p>
  Use this page to search through the different items that we stock.  All searches are done
by 

key words.  If using multiple words please use a comma after every different word.</i>.
 </p>
 <p>
 <FORM ACTION="WEB-INF/classes/SearchServlet" METHOD="GET">
     <INPUT TYPE="TEXT" NAME="itemvalue" SIZE="100" VALUE="type search criteria here"><br>
     <INPUT TYPE="SUBMIT">
 </FORM>
 </p>
 <p>
 <a href="search.jsp">Return to the main search page</a>
 </p>
   </td>
   </tr>
   </table>
