jquery - Configuring a Java HTTP servlet in Netbeans 7.3 -


i've upgraded netbeans 7.3, , quite don't of project configuration , interface. example, once used see source packages java classes, i'm not able see them in file panel. have package called batchutility containing http servlet called batchqueryservlet.

i have post json batchqueryservlet via jquery.ajax() function , i'm not able map servlet.

since netbeans 7.3 doesn't ship config file, i've created 1 myself clicking on web-inf folder>new>web.xml file , wrote follows:

<web-app xmlns="http://java.sun.com/xml/ns/javaee"      xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"      xsi:schemalocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"      version="3.0"> <welcome-file-list>     <welcome-file>index.html</welcome-file>     <welcome-file>index.htm</welcome-file>     <welcome-file>index.jsp</welcome-file>     <welcome-file>default.html</welcome-file>     <welcome-file>default.htm</welcome-file>     <welcome-file>default.jsp</welcome-file>   </welcome-file-list>   <servlet>     <servlet-name>batchqueryservlet</servlet-name>     <servlet-class>/batchutility.batchqueryservlet</servlet-class>   </servlet>   <servlet-mapping>     <servlet-name>batchqueryservlet</servlet-name>     <url-pattern>/batchqueryservlet</url-pattern>   </servlet-mapping> </web-app>

but still, when issuing request, 404 error:

  $.ajax({                             url: "/batchqueryservlet",                             contenttype: 'application/json',                             data: json,                             accept: "text/html",                             success: function(data, textstatus, jqxhr) {                                 alert(data);                             },                             type: "post"                         });

now, i'm pretty sure doesn't find class because if call servlet name classnotfound exception. how fix that? (a quick , dirty solution using jsp i'd rather not it).

ps: use version 7.0.34 of tomcat.

edit problem should use proper src/java path storing .java classes instead of plain folder (this reason couldn't see packages). i've fixed it. anyway time!

you have leading slash in

<servlet-class>/batchutility.batchqueryservlet</servlet-class>

remove , things should work.

change ajax url: either "batchqueryservlet" or "/web-app-name/batchqueryservlet"

edit:

once deployed web application's folder structure should like: (/ indicates directory)

tomcat-home/  |- webapps/    |- batchwebapp/ //<-- context-root (web-app's name)      |- *.html, *.jsp etc.      |- web-inf/         |- web.xml         |- lib/           |- *.jar files         |- classes/ //<-- servlets go here           |- batchutility/ //<-- required package/folder structure             |- batchqueryservlet.class

if you're using ide (like eclipse) same you.
