java.lang.IllegalArgumentException: Invalid coreservlets.ShowItems_ArrayList

Question

Eclipse Version: Kepler Service Release 1

Build id: 20130919-0819

Steps taken so far:

(1) Deleted the .snap file located in the directory
<workspace-directory>\.metadata\.plugins\org.eclipse.core.resources
(2) Deleted tmp folder in the following directory
<workspace-directory>\.metadata\.plugins\org.eclipse.wst.server.core
(3) Clean project & server

(4) Reconfigured the server by deleting the current server, & adding new server

(5) Just to ensure changes to reflect, restarted Eclipse every time after performing above steps.

However, all the tips & tricks seems to have gone in vain.

web.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    version="3.0">

    <servlet>
        <servlet-name>ShowItems_ArrayList</servlet-name>
        <servlet-class>coreservlets.ShowItems_ArrayList</servlet-class>
    </servlet>


    <servlet-mapping>
        <servlet-name>ShowItems_ArrayList</servlet-name>
        <url-pattern>coreservlets.ShowItems_ArrayList</url-pattern>
    </servlet-mapping>

</web-app>

seems the problem is `Invalid ` thing. could you post your web.xml here? — kucing_terbang, Apr 09 '15 at 09:31
**web.xml file** ` ShowItems_ArrayList coreservlets.ShowItems_ArrayList ShowItems_ArrayList coreservlets.ShowItems_ArrayList ` — mindfreak, Apr 09 '15 at 09:34
@kucing_terbang - **`web.xml file is attached per your request.`** — mindfreak, Apr 09 '15 at 11:50
well, you could change the url pattern by adding slash (like what Necreaux has posted) — kucing_terbang, Apr 09 '15 at 13:10

Your url-pattern is not in the correct format. It needs to start with a slash. While not an exact duplicate, see this question:

Why should url-pattern in servlet mapping start with forward slash(/)
