Hey Everyone,

I am creating an app in struts 1.3. I am trying to validate a single form on multiple actions.
Is there a way I can validate a particular field on the form only when I am sending it to some specific action?

Thanks

Hi

I am trying to create a simple struts app with tiles.
Could anyone tell me what this error is about?

java.lang.NullPointerException at org.apache.struts.chain.commands.servlet.PerformForward.handleAsForward(PerformForward.java:113) at org.apache.struts.chain.commands.servlet.PerformForward.perform(PerformForward.java:96) at org.apache.struts.chain.commands.AbstractPerformForward.execute(AbstractPerformForward.java:54) at org.apache.struts.chain.commands.ActionCommandBase.execute(ActionCommandBase.java:51)

Hi

I am trying to create a simple struts app with tiles.
Going to the context-root gives me "java.lang.ClassNotFoundException: org.apache.struts.actions.ForwardAction"
The app's welcome file is 'index.jsp' which forwards to 'home.do'

index.jsp
<jsp:forward page="home.do"/>

web.xml snippet
<servlet-mapping> <servlet-name>action</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping>

struts-config.xml snippet
<action-mappings> <action path="/home" type="org.apache.struts.actions.ForwardAction" parameter="homepage"/> </action-mappings> <plug-in className="org.apache.struts.tiles.TilesPlugin"> <set-property property="definitions-config" value="/WEB-INF/tiles-defs.xml"/> </plug-in>

tiles-defs.xml
<tiles-definitions> <definition name="layout" path="/layouts/layout.jsp"> <put name="body" value=""/> </definition> <definition name="homepage" extends="layout"> <put name="body" value="/views/home.jsp"/> </definition> </tiles-definitions>

I searched for similar issues, but couldn't find a satisfactory response.
Am I missing something over here?

Thanks

I created a new index.html and set it as the welcome file in web.xml

index.html
<meta http-equiv="Refresh" CONTENT="0; URL=/Basic_Struts2_Ant/index.action"/>

I pushed the index.jsp into a 'jsp' dir inside WebContent.

struts.xml
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> <constant name="struts.devMode" value="true" /> <package name="default" namespace="/" extends="struts-default"> <action name="index"> <result>/jsp/index.jsp</result> </action> </package> </struts>

Now pointing to the context root takes me to index.html and consequently to index.action
But I am still getting a 404 instead of the jsp/index.jsp

I am facing a similar problem with the routing to index.action failing with a 404. However if i go to the context root of the app, it goes to index.jsp as expected.

web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <display-name>Basic_Struts2_Ant</display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>

struts.xml
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> <constant name="struts.devMode" value="true" /> <package name="default" namespace="/" extends="struts-default"> <action name="index"> <result>/index.jsp</result> </action> </package> </struts>

I am using Weblogic 9.2 as the application server and deploying the app as a war.
Please help.

Thanks

Why don't you try out EJB3's very own Object Relational Mapping API - JPA(Java Persistence API), instead of Hibernate.

For you 1st query, you could create a Final class containing all the static final constants you want to use across classes/methods and import the class to use them.

For you second query, it depends on the type of enterprise bean you want. E.g for a Message Driven Bean, the method call would come inside a onMessage() method.

Hello

I am using JAXB to marshall an object into XML. It looks like JAXB generates the XML with elements in alphabetical order.
Is there a way in which I can restrict the generated XML to have elements in the same order as the XSD?

Thanks

Hi

I am trying to create a XSD for using in a JAXB application.
I am getting the following error:

"Error resolving component 'name'. It was detected that 'name' has no namespace."
on
<xs:element ref="name"/>


<?xml version="1.0" encoding="UTF-8"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.example.org/shiporder" xmlns:tns="http://www.example.org/shiporder" elementFormDefault="qualified"> <!-- definition of simple elements --> <xs:element name="orderperson" type="xs:string"/> <xs:element name="name" type="xs:string"/> <xs:element name="address" type="xs:string"/> <xs:element name="city" type="xs:string"/> <xs:element name="country" type="xs:string"/> <xs:element name="title" type="xs:string"/> <xs:element name="note" type="xs:string"/> <xs:element name="quantity" type="xs:positiveInteger"/> <xs:element name="price" type="xs:decimal"/> <!-- definition of attributes --> <!-- <xs:attribute name="orderid" type="xs:string"/> --> <!-- definition of complex elements --> <xs:element name="shipto"> <xs:complexType> <xs:sequence> <xs:element ref="name"/> <xs:element ref="address"/> <xs:element ref="city"/> <xs:element ref="country"/> </xs:sequence> </xs:complexType> </xs:element> <xs:element name="item"> <xs:complexType> <xs:sequence> <xs:element ref="title"/> <xs:element ref="note" minOccurs="0"/> <xs:element ref="quantity"/> <xs:element ref="price"/> </xs:sequence> </xs:complexType> </xs:element> <xs:element name="shiporder"> <xs:complexType> <xs:sequence> <xs:element ref="orderperson"/> <xs:element ref="shipto"/> <xs:element ref="item" maxOccurs="unbounded"/> </xs:sequence> </xs:complexType> </xs:element> </xs:schema>

Any ideas?

Hi

I know this question has been raised and discussed many times in this forum, but none of the threads were able to solve the issue. I am facing the same dreaded exception:
java.lang.IllegalStateException: Duplicate component ID 'logonForm:unameLbl' found in view.

I have the following code in my login.jsp
<f:view> <h:form id="logonForm"> <h:panelGrid columns="3"> <h:outputLabel id="unameLbl" value="Username:" /> <h:inputText id="username" value="#{UserBean.username}" required="true"> <f:validateLength minimum="4"/> </h:inputText> <h:message for="username" id="unameMsg" styleClass="validationError" /> <h:outputLabel id="passwdLbl" value="Password:" /> <h:inputSecret id="password" value="#{UserBean.password}" required="true"/> <h:message for="password" id="passwdMsg" styleClass="validationError" /> <h:commandButton type="submit" value="Log On" id="button1" action="#{UserBean.authenticate}" /> <h:commandButton type="reset" value="Reset" id="button2" /> </h:panelGrid> </h:form> </f:view>

I simply fail to understand, where is such an id coming from, when I have explicitly given ids to all the components in the page!
Is this an issue with JSF or the application server (in my case weblogic 9.2)?

Any suggestions/pointers?

Hi..

I am creating a web app in Struts 1.3. One of the JSPs has a requirement wherein a multiselect box and a textbox need to get filled, based on the selection in a dropdown.
I am not sure if there is any standard/well known way of doing this in Struts.
Any suggestions/pointers would be really great.

Thanks
