Ola pessoal.
Estou com uma aplicação utilizando Struts, e ao rodar a página principal que usa uma action do Struts, está ocorrendo o seguinte erro :
SEVERE: Error creating form bean of class soares.luis.struts.LoginForm java.lang.NullPointerException
Segue meu arquivo struts-config.xml abaixo :
<?xml version="1.0" encoding="ISO-8859-1" ?> <!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_2.dtd"> <struts-config> <!-- ============================================ Data Source Configuration --> <!-- <data-sources> <data-source type="org.apache.commons.dbcp.BasicDataSource"> <set-property property="driverClassName" value="org.postgresql.Driver" /> <set-property property="url" value="jdbc:postgresql://localhost/mydatabase" /> <set-property property="username" value="me" /> <set-property property="password" value="test" /> <set-property property="maxActive" value="10" /> <set-property property="maxWait" value="5000" /> <set-property property="defaultAutoCommit" value="false" /> <set-property property="defaultReadOnly" value="false" /> <set-property property="validationQuery" value="SELECT COUNT(*) FROM market" /> </data-source> </data-sources> --> <!-- ================================================ Form Bean Definitions --> <form-beans> <form-bean name="LoginForm" type="soares.luis.struts.LoginForm"/> <!-- sample form bean descriptor for an ActionForm <form-bean name="inputForm" type="app.InputForm"/> end sample --> <!-- sample form bean descriptor for a DynaActionForm <form-bean name="logonForm" type="org.apache.struts.action.DynaActionForm"> <form-property name="username" type="java.lang.String"/> <form-property name="password" type="java.lang.String"/> </form-bean> end sample --> </form-beans> <!-- ========================================= Global Exception Definitions --> <global-exceptions> <!-- sample exception handler <exception key="expired.password" type="app.ExpiredPasswordException" path="/changePassword.jsp"/> end sample --> </global-exceptions> <!-- =========================================== Global Forward Definitions --> <global-forwards> <!-- Default forward to "Welcome" action --> <!-- Demonstrates using index.jsp to forward --> <forward name="welcome" path="/Welcome.do"/> <forward name="login" path="/pages/login.jsp"> </forward> </global-forwards> <!-- =========================================== Action Mapping Definitions --> <action-mappings> <!-- Default "Welcome" action --> <!-- Forwards to Welcome.jsp --> <!-- Aqui está o meu Action !! --> <action path="/Welcome" forward="/pages/Welcome.jsp"/> <action path="/Login" type="soares.luis.struts.LoginAction" name="LoginForm" scope="request" validate="false" input="/pages/login.jsp"> <forward name="success" path="/pages/intranetInicio.jsp"/> <forward name="failure" path="/pages/login.jsp"/> </action> <!-- sample input and input submit actions <action path="/Input" type="org.apache.struts.actions.ForwardAction" parameter="/pages/Input.jsp"/> <action path="/InputSubmit" type="app.InputAction" name="inputForm" scope="request" validate="true" input="/pages/Input.jsp"/> <action path="/edit*" type="app.Edit{1}Action" name="inputForm" scope="request" validate="true" input="/pages/Edit{1}.jsp"/> end samples --> </action-mappings> <!-- ============================================= Controller Configuration --> <controller processorClass="org.apache.struts.tiles.TilesRequestProcessor"/> <!-- ======================================== Message Resources Definitions --> <message-resources parameter="MessageResources" /> <!-- =============================================== Plug Ins Configuration --> <!-- ======================================================= Tiles plugin --> <!-- This plugin initialize Tiles definition factory.

Não estou conseguindo resolver este problema.
Alguém poderia me ajudar ?
Abraço a todos.

a classe está criada com os atributos que são utilizados no jsp, estão listados no form?
