Hi All,
I am a newbee to struts and trying some hands on it. I was just trying to 
develop a simple login form but getting following exception on initial run only.
---------------------------------------------------------------------------------------------
SEVERE: Error creating form bean of class 
com.abc.struts.form.LoginFormjava.lang.NullPointerExceptionat 
org.apache.struts.config.FormBeanConfig.createActionForm(FormBeanConfig.java:212)at

---------------------------------------------------------------------------------------------
I tried searching thru all forums from last 2 days but could not found any 
solution to the issue. This seems to be a very common problem but I don't know 
why its not going away. I am really stuck up.
Below are the listing of files required to analyize the cause of error.
web.xml------------&lt;?xml version="1.0" encoding="UTF-8"?&gt;&lt;!DOCTYPE 
web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" 
"http://java.sun.com/dtd/web-app_2_3.dtd"&gt;&lt;web-app&gt;&nbsp; 
&lt;servlet&gt;&nbsp;&nbsp;&nbsp; 
&lt;servlet-name&gt;action&lt;/servlet-name&gt;&nbsp;&nbsp;&nbsp; 
&lt;servlet-class&gt;org.apache.struts.action.ActionServlet&lt;/servlet-class&gt;&nbsp;&nbsp;&nbsp;
 &lt;init-param&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
&lt;param-name&gt;config&lt;/param-name&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
&lt;param-value&gt;/WEB-INF/struts-config.xml&lt;/param-value&gt;&nbsp;&nbsp;&nbsp;
 &lt;/init-param&gt;&nbsp;&nbsp;&nbsp; 
&lt;init-param&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
&lt;param-name&gt;debug&lt;/param-name&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
&lt;param-value&gt;3&lt;/param-value&gt;&nbsp;&nbsp;&nbsp; 
&lt;/init-param&gt;&nbsp;&nbsp;&nbsp; 
&lt;init-param&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
&lt;param-name&gt;detail&lt;/param-name&gt;&nbsp;&nbsp;&nbsp;&
 nbsp;&nbsp; &lt;param-value&gt;3&lt;/param-value&gt;&nbsp;&nbsp;&nbsp; 
&lt;/init-param&gt;&nbsp;&nbsp;&nbsp; 
&lt;load-on-startup&gt;0&lt;/load-on-startup&gt;&nbsp; &lt;/servlet&gt;&nbsp; 
&lt;servlet-mapping&gt;&nbsp;&nbsp;&nbsp; 
&lt;servlet-name&gt;action&lt;/servlet-name&gt;&nbsp;&nbsp;&nbsp; 
&lt;url-pattern&gt;*.do&lt;/url-pattern&gt;&nbsp; 
&lt;/servlet-mapping&gt;&nbsp; &lt;welcome-file-list&gt;&nbsp;&nbsp;&nbsp; 
&lt;welcome-file&gt;index.jsp&lt;/welcome-file&gt;&nbsp; 
&lt;/welcome-file-list&gt;&nbsp; &lt;taglib&gt;&nbsp; 
&nbsp;&lt;taglib-uri&gt;/WEB-INF/struts-html.tld&lt;/taglib-uri&gt;&nbsp; 
&nbsp;&lt;taglib-location&gt;/WEB-INF/struts-html.tld&lt;/taglib-location&gt;&nbsp;
 &lt;/taglib&gt;&lt;/web-app&gt;
index.jsp---------......&lt;body&gt;&nbsp;&nbsp;&nbsp; &lt;html:link 
page="/home.do"&gt;Login&lt;/html:link&gt;&nbsp; &lt;/body&gt;.....
struts-config.xml-----------------&lt;?xml version="1.0" 
encoding="UTF-8"?&gt;&lt;!DOCTYPE struts-config PUBLIC "-//Apache Software 
Foundation//DTD Struts Configuration 1.2//EN" 
"http://struts.apache.org/dtds/struts-config_1_2.dtd"&gt;
&lt;struts-config&gt;&nbsp; &lt;data-sources /&gt;&nbsp; &lt;form-beans 
&gt;&nbsp;&nbsp;&nbsp; &lt;form-bean name="loginForm"

&nbsp; &lt;/form-beans&gt;
&nbsp; &lt;global-exceptions /&gt;&nbsp; &lt;global-forwards /&gt;&nbsp;

name="loginForm"&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
path="/empLogin"&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
scope="request"&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
type="com.siemens.struts.action.EmpLoginAction"&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
validate="false" /&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; 
&lt;action forward="/Login.jsp" path="/home" /&gt;
&nbsp; &lt;/action-mappings&gt;
&nbsp; &lt;message-resources 
parameter="com.siemens.struts.ApplicationResources" /&gt;&lt;/struts-config&gt;
Login.jsp---------
&lt;body&gt;&nbsp;&nbsp;&nbsp; &lt;html:form action="/empLogin" method="post" 
focus="login"&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;table 
border="0"&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
&lt;tr&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
&lt;td&gt;Login:&lt;/td&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
 &lt;td&gt;&lt;html:text property="login" 
/&gt;&lt;/td&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
&lt;/tr&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
&lt;tr&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
&lt;td&gt;Password:&lt;/td&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
 &lt;td&gt;&lt;html:password property="password" 
/&gt;&lt;/td&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
&lt;/tr&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
&lt;tr&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;td 
colspan="2" 
align="center"&gt;&lt;html:submit&gt;Login&lt;/html:submit&gt;&lt;/td&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbs
 p;&nbsp;&nbsp; &lt;/tr&gt;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
&lt;/table&gt;&nbsp;&nbsp;&nbsp; &lt;/html:form&gt;&nbsp; &lt;/body&gt;
I can also provide the form bean and action class if required but I believe it 
won't add to solving the problem as the exception occurs when I click on the 
link on index.jsp and then it tries to render the Login.jsp.
Please help.
