Bussines rules problems using Struts + BC4J

Hi, I'm using struts + bc4j and I have some problems with the validations made on the entities.
Looks like sometimes, struts didn't shows the error message until the commit is made. But the problem is that on the navigator shows me the stack trace of the exception, but only when I do the commit of the transaction.
In the test of the application module, the business rules works perfectly.
If somebody can help me i will aprecciate it.
Thanks
Daniel Gonzalez

There are already some threads on this topic.
Unfortunately, they don't give solutions - not yet ;)

Urgent problem in struts bc4j app

The problem occurs between the Controller an the View Layer(can I debug there?) Anyway, I can see the data in the Action class, but not in the jsp page, there's just one row (the first).
Thank you.
I'm using the 9.0.3.3 build 1205
The Action class:
public class ShowneuebehauftrAction extends Action
public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response)
BC4JContext context = BC4JContext.getContext(request);
ViewObject vo = context.getApplicationModule().findViewObject("BehauftrNeu");
//here the output looks fine
Row r = vo.first();
while (r != null)
for (int i = 0; i < vo.getAttributeCount(); i++)
String attrName = vo.getAttributeDef(i).getName();
String attrVal = r.getAttribute(i).toString();
System.out.println(attrName + " = " + attrVal);
r = vo.next();
return BC4JUtils.getForwardFromContext(context, mapping);
And the jsp page:
<%@ page language="java" errorPage="errorpage.jsp" contentType="text/html;charset=windows-1252" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/webapp/DataTags.tld" prefix="jbo" %>
<html>
<head>
<META NAME="GENERATOR" CONTENT="Oracle JDeveloper">
<LINK REL=STYLESHEET TYPE="text/css" HREF="bc4j.css">

</head>
<body>
<table border="0" bgcolor="#003399">
<tr>
<th><font color="white" size="3"><bean:message key="behauftr.nr"/></font></th>
<th><font color="white" size="3"><bean:message key="behauftr.wunschdatum"/></font></th>
<th><font color="white" size="3"><bean:message key="behauftr.status"/></font></th>
<th> </th>
</tr>
<jbo:RowsetIterate datasource="DataaccessModule.BehauftrNeu" userange="true" >
<tr bgcolor="#f3f3f3">

<jbo:ShowValue dataitem="Nr"/>
</td>
<td>
<jbo:ShowValue dataitem="Wunschdatum"/>
</a>
</td>
<td align="right">
<jbo:ShowValue dataitem="BasNr"/>
</td>
</tr>
</jbo:RowsetIterate>
</table>
</body>
</html>

There's another question: I tried to format a date field to SimpleDate format dd.MM.yyyy - in the Entity's and ViewObject's Attribute-Editor-Control-Hint.
It works fine in the BC-App-Module, but in the Action class there's the yyyy-MM-dd format back again (and of course in the jsp page as well). Does this have to be handled in the Action class?
But, more important, I still can't figure out why there's only one row in the jsp page - as described earlier -
Thanks in advance for your help.

Problem using struts tags in .jsp

I have a page that fills in the appropriate user information in text fields when viewed. The problem is, i want to have a text field that shows the full name, but i only have getter and setter methods for firstname and lastname in my form bean. Is there a way to combine firstname and lastname to display the fullname using the <html:text> tag ???

You can use an ActionForm for your view that differs from the bean you are using. DynaActionForm would be ideal because it can be tedious to have a full complement of view beans that mirror your value objects.
The idea is to loadup a DynaActionForm with the values for the view before the JSP is called in an Action. The following shows the parts of this and some code for execute() that creates DynaActionForm.
If you have this bean in myapp/Contact.java
package myapp;
public class Contact {
private String firstName,lastName;
public String getFirstName() { return firstName; }
public String getLastName() { return lastName; }
public void setFirstName(String _firstName) { firstName = _firstName; }
public void setLastName(String _lastName) { lastName = _lastName; }
}Put this in the appropriatesecions in struts-config.xml
<form-bean name="ContactActionForm" type="org.apache.struts.action.DynaActionForm">
<form-property name="fullName" type="java.lang.String"/>
</form-bean>
<action path="/showContactForm"
        type="myapp.ShowContactActionForm">
<forward name="success" path="/contactActionForm.jsp">
</action>
<action path="/handleContact"
        name="ContactActionForm"
        type="myapp.HandleContactActionForm">
<forward name="success" path="/contactActionForm.jsp">
</action>And for the execute method in the ShowContactActionForm put...
Contact contact = db.getContact(contactId);
ModuleConfig mc = _mapping.getModuleConfig();
FormBeanConfig fbc = mc.findFormBeanConfig("ContactForm");
DynaActionFormClass dafc =
DynaActionFormClass.createDynaActionFormClass(fbc);
DynaActionForm theForm = (DynaActionForm)dafc.newInstance();
theForm.initialize(_mapping);
theForm.set("fullName", contact.getFirstName() + " " + contact.getLastName());
_request.setAttribute("ContactForm", theForm);
fwd = _mapping.findForward("success");

Struts+ bc4j insensitive case search using queryAction

I'm working in a new project using Struts+bc4j.
the queryAction, when it executes a query using this attributes and applying a new viewcritteria, it works in a case-sensitive mode. I'm looking for a way to make it non-case-sensitive in a View OBject level.

Change the query to do this e.g.
where lower(Emp.ENAME) = lower(:1) or whatever

Using Struts with JDeveloper, BC4J and OC4J 9.0.2

Is it feasible to use Struts with JDeveloper 9.0.2, BC4J 9.0.2 and OC4J 9.0.2? We have an application that uses the BC4J JBO tags in version 9.0.2. We wish to use Struts and we want to retain the use of the JBO tags. Is there a way to do this without upgrading to 9.0.3?

Here are two related questions:
Can we upgrade to oracle9iAS 9.0.3 yet still use JDeveloper 9.0.2 and BC4J/JBO 9.0.2?
Can we upgrade to JDeveloper 9.0.3 and BC4J/JBO 9.0.3 yet still deploy to oracle9iAS 9.0.2?

Problem in struts using JDeveloper10.1.2

hi
Iam completly new to jdeveloper
Iam using jdev 10.1.2 for my simple struts application
I have
action class -- LoginAction
form bean -- login (using DynaActionForm)
login.jsp to enter username
success.jsp for welcom msg
failure.jsp --- in this i use one submit btn when i press this it will go to login.jsp for relogin
<form action="/login.jsp">....
the problem is
In LoginAction
String password=(String)((DynaActionForm)form).get("password");
// String pwd =request.getParameter("username");
if(password.equalsIgnoreCase("oracle"))
return mapping.findForward("success");
else
return mapping.findForward("failure");
iam import all the class for the respective reff variables.
But it will indicate err underline(blue) under text which are in bold saying msgs as

Content-type problems while using struts+tomcat+apache+mod_jk

Hi!
Could anyone tell me how to solve the following problem.
Struts-application works under apache + mod_jk + tomcat 3.3.1. Operating system is Linux.
It's impossible to me to make tomcat to send HTTP-answers in UTF-8.
I was trying the following:
1. Set <DecodeInterceptor defaultEncoding="UTF-8" /> in server.xml
(Has no effect. Tomcat responds with Content-Type: text/html; charset=iso-8859-1)
2. Insert <%@ page contentType="text/html; charset=utf-8"%> into each page header.
(Works fine but when struts-application gets GET/POST-data the two-bytes national characters
are comverted into "?"-symbols)
Is there any way to make tomcat 3.3.1 to send HTTP-answers in UTF-8?

I don't know what the DecodeInterceptor does... but....
If you use number 2, you are only telling the browser what that page's output is. When you process the data, Tomcat for some reason always reads it as ISO8895-1, so you need to tell Tomcat to change it to UTF-8. You can do that by calling request.setCharacterEncoding("UTF-8"), either in the JSP page, or if you need it in a servlet, you can do that in a filter...
It's somewhat described here how to set it up...

but without using this attribute struts doesn't support the "upload" i.e, form file... its throwing another exeception..
could you anyone please let me know whether i can change my OC4J server version of anything need to do..
many thanks in advance

Anyone deploy ADF(UIX,Struts,BC4J) to 9iAS 9.02?

Has anyone been successful in deploying a ADF 10g app using UIX/Struts/BC4J to Oracle 9iAS 9.02?

Deploying a UIX application directly from JDeveloper 10g to iAS 9.0.2 isn't supported out of the box. You can deploy directly to iAS 10g (9.0.4), standalone OC4J 10g (9.0.4) instances (one is included with JDeveloper 10g), iAS 9.0.3 Java edition, standalone OC4J 9.0.3, and selected third party servlet engines.
There are two issues that you would need to workaround to deploy a 10g ADF application to iAS 9.0.2. One issue is that 9.0.2 versions of some of the ADF libraries (BC4J and UIX for example) are on the global application.xml classpath of the iAS 9.0.2 customer home OC4J instance. You would need to manually upgrade your 9.0.2 instance to have all of the ADF 10g libraries. The second issue is that some of the ADF 10g libraries (like BC4J) require JDK 1.4, and iAS 9.0.2 shipped with an earlier version of the JDK. I personally don't know if using iAS 9.0.2 with JDK 1.4 is a supported combination, but I will try to find out for you.
By the way, you might wonder why we don't have these same problems with with iAS 9.0.3 and 9.0.4 since the ADF 10g libraries are more recent than what shipped with those releases. In OC4J 9.0.3 and 9.0.4 there is a "search-local-classes-first" option in orion-web.xml that allows classes provided as part of a web application to be loaded in preference to what is on the global application.xml classpath. We use this feature to deploy ADF 10g applications (and include the JARs for some of the ADF libraries in the WEB-INF/lib of the application). In addition, there is a tool called the ADF Installer that is part of JDeveloper that will upgrade versions of some of the backward compatible ADF libraries (like BC4J) in the global application.xml.

How to assign bean value to a local variable in JSP using struts.

Hi everybody!
I've a problem that puzzled me on how to assign a bean value to a local variable like String in JSP using struts.
we can have someting like this to display the value
<bean:write name="detailService" property="status" />or
<bean:define id="theStatus" name="detailService" property="status"/>
This is country: <%=theStatus%>but an error occured when I tried like this:
String currentStatus = "<bean:define id="theStatus" name="detailService" property="status"/>";
or
String currentStatus = "<bean:write name="detailService" property="status" />";Is there a way to do this?.....
Any help pretty much appreciated

Java != JSP.
The <bean:define> and <bean:write> tags are custom tags meant to appear in the HTML section of a JSP file, as opposed to the scriptlet section. They actually get turned into java code as part of the translation process.
The <bean:write> tag naturally just writes out what you tell it to.
The <bean:define> tag defines a local variable, and gives it a value.
this should do it.
<bean:define id="theStatus" name="detailService" property="status" type="java.lang.String"/>
<%
String currentStatus = theStatus;
%>With the advent of JSTL, you shouldn't really need to use scriptlet code anymore. Personally I am for 0% scriptlet code in any jsp I write.

HOWTO: Using a BC4J Application Module in an Stateless EJB Session Bean

HOWTO: Using a BC4J Application Module in an Stateless EJB Session Bean
by Steve Muench
Overview
BC4J provides automatic facilities for deploying any application module as a stateful EJB session bean. If you want to leverage the features of your BC4J application module from a stateless EJB session bean, it's not automatic but it is straightforward to implement. This howto article explains the details.
For our example, we will create a stateless EJB session bean that uses a container-managed transaction. To keep things simple, let's assume the session bean has a single public method on its remote interface named createDepartment() with the following signature:
public void createDepartment(int id, String name, String loc) throws AppException
AppException is an example of an application-specific exception that our method will throw if any problems arise during its execution.The goal of this article is to illustrate how to use the BC4J application module named com.example.hr.HRApp as part of the implementation of this createDepartment method on our stateless enterprise bean. Let's assume that the HRApp application module has a view object member named Departments, based on the com.example.hr.DeptView view object, based on the familiar DEPT table and related to the com.example.hr.Dept entity object so our view can be updateable.
Creating the Stateless Session Bean
We can start by using the JDeveloper Enterprise Bean wizard to create a new stateless session bean called StatelessSampleEJB implemented by:[list][*]com.example.StatelessSampleEJBBean (Bean class)[*]com.example.StatelessSampleEJBHome (Home interface)[*]com.example.StatelessSampleEJB (Remote interface)[list]
We then use the EJB Class Editor to add the createDepartment method to the remote interface of StatelessSampleEJB with the signature above. We edit the remote interface to make sure that it also reflects that the createDepartment method thows the AppException like this:
package com.example;
import javax.ejb.EJBObject;
import java.rmi.RemoteException;
public interface StatelessSampleEJB extends EJBObject {
void createDepartment(int id, String name, String loc)
throws RemoteException,AppException;
}Before we start adding BC4J into the picture for our implementation, our StatelessSampleEJBBean class looks like this:
package com.example;
import javax.ejb.SessionBean;
import javax.ejb.SessionContext;
public class StatelessSampleEJBBean implements SessionBean {
public void ejbCreate(){}
public void ejbActivate(){}
public void ejbPassivate(){}
public void ejbRemove(){}
public void setSessionContext(SessionContext ctx){
public void createDepartment(int id, String name, String loc)
throws AppException {
    // TODO: Implement method here
}We can double-click on the ejb-jar.xml file in our project to see the XML deployment descriptor for the bean we just created:
<ejb-jar>
   <enterprise-beans>
      <session>
         <description>Session Bean ( Stateless )</description>
         <display-name>StatelessSampleEJB</display-name>
         <ejb-name>StatelessSampleEJB</ejb-name>
         <home>com.example.StatelessSampleEJBHome</home>
         <remote>com.example.StatelessSampleEJB</remote>
         <ejb-class>com.example.StatelessSampleEJBBean</ejb-class>
         <session-type>Stateless</session-type>
         <transaction-type>Container</transaction-type>
      </session>
   </enterprise-beans>
</ejb-jar>We need to add the extra <assembly-descriptor> section in this file to indicate that the createDepartment method will require a transaction. After this edit, the ejb-jar.xml file looks like this:
<ejb-jar>
   <enterprise-beans>
      <session>
         <description>Session Bean ( Stateless )</description>
         <display-name>StatelessSampleEJB</display-name>
         <ejb-name>StatelessSampleEJB</ejb-name>
         <home>com.example.StatelessSampleEJBHome</home>
         <remote>com.example.StatelessSampleEJB</remote>
         <ejb-class>com.example.StatelessSampleEJBBean</ejb-class>
         <session-type>Stateless</session-type>
         <transaction-type>Container</transaction-type>
      </session>
   </enterprise-beans>
   <assembly-descriptor>
      <container-transaction>
         <method>
            <ejb-name>StatelessSampleEJB</ejb-name>
            <method-name>createDepartment</method-name>
            <method-params>
               <method-param>int</method-param>
               <method-param>java.lang.String</method-param>
               <method-param>java.lang.String</method-param>
            </method-params>
         </method>
         <trans-attribute>Required</trans-attribute>
      </container-transaction>
   </assembly-descriptor>
</ejb-jar>
Aggregating a BC4J Application Module
With the EJB aspects of our bean setup, we can proceed to implementing the BC4J application module aggregation.
The first thing we do is add private variables to hold the EJB SessionContext and the instance of the aggregated BC4J ApplicationModule, like this:
// Place to hold onto the aggregated appmodule instance
transient private ApplicationModule _am = null;
// Remember the SessionContext that the EJB container provides us
private           SessionContext    _ctx = null;and we modify the default, empty implementation of the setSessionContext() method to remember the session context like this:
public void setSessionContext(SessionContext ctx){ _ctx = ctx; }We add additional constants that hold the names of the J2EE datasource that we want BC4J to use, as well as the fully-qualified name of the BC4J application module that we'll be aggregating:
// JNDI resource name for the J2EE datasource to use
private static final String DATASOURCE = "jdbc/OracleCoreDS";
// Fully-qualified BC4J application module name to aggregate
private static final String APPMODNAME = "com.example.hr.HRApp";We expand the now-empty ejbCreate() and ejbRemove() methods to create and destory the aggregated instance of the BC4J application module that we'll use for the lifetime of the stateless session bean. When we're done, ejbCreate() it looks like this:
public void ejbCreate() throws CreateException {
try {
    // Setup a hashtable of environment parameters for JNDI initial context
    Hashtable env = new Hashtable();
    env.put(JboContext.INITIAL_CONTEXT_FACTORY,JboContext.JBO_CONTEXT_FACTORY);
    // NOTE: we want to use the BC4J app module in local mode as a simple Java class!
    env.put(JboContext.DEPLOY_PLATFORM, JboContext.PLATFORM_LOCAL);
    env.put(PropertyConstants.INTERNAL_CONNECTION_PARAMS,DATASOURCE);
    // Create an initial context, using this hashtable of environment params
    InitialContext ic = new InitialContext(env);
    // Lookup a home interface for the application module
    ApplicationModuleHome home = (ApplicationModuleHome)ic.lookup(APPMODNAME);
    // Using the home, create the instance of the appmodule we'll use
    _am = home.create();
    // Register the BC4J factory to handle EJB container-managed transactions
    registerContainerManagedTransactionHandlerFactory();
catch(Exception ex) {
     ex.printStackTrace();
    throw new CreateException(ex.getMessage());
}and ejbRemove() looks like this:
public void ejbRemove() {
try {
    // Cleanup any appmodule resources before getting shutdown
    _am.remove();
catch(JboException ex) { /* Ignore */ }
}The helper method named reigsterContainerManagedTransactionHandlerFactory() looks like this:
private void registerContainerManagedTransactionHandlerFactory() {
SessionImpl session = (SessionImpl)_am.getSession();
session.setTransactionHandlerFactory(
    new TransactionHandlerFactory() {
      public TransactionHandler createTransactionHandler() {
        return new ContainerManagedTxnHandlerImpl();
      public JTATransactionHandler createJTATransactionHandler() {
        return new ContainerManagedTxnHandlerImpl();
}The last detail is to use the BC4J appmodule to implement the createDepartment() method. It ends up looking like this:
public void createDepartment(int id, String name, String loc)
throws AppException {
try {
    // Connect the AM to the datasource we want to use for the duration
    // of this single method call.
    _am.getTransaction().connectToDataSource(null,DATASOURCE,false);
    // Use the "Departments" view object member of this AM
    ViewObject departments = _am.findViewObject("Departments");
    // Create a new row in this view object.
    Row newDept = departments.createRow();
    // Populate the attributes from the parameter arguments.
    newDept.setAttribute("Deptno", new Number(id));
    newDept.setAttribute("Dname", name);
    newDept.setAttribute("Loc", loc);
    // Add the new row to the view object's default rowset
    departments.insertRow(newDept);
    // Post all changes in the AM, but we don't commit them. The EJB
    // container managed transaction handles the commit.
    _am.getTransaction().postChanges();
catch(JboException ex) {
    // To be good EJB Container-Managed Transaction "citizens" we have
    // to mark the transaction as needing a rollback if there are problems
    _ctx.setRollbackOnly();
    throw new AppException("Error creating dept "+ id +"\n"+ex.getMessage());
finally {
    try {
      // Disconnect the AM from the datasource we're using
      _am.getTransaction().disconnect();
    catch(Exception ex) { /* Ignore */ }
Building a Test Client
With the EJB-Tier work done, we can build a sample client program to test this new stateless EJB Session Bean by selecting the bean in the Oracle9i JDeveloper IDE and choosing "Create Sample Java Client" from the right-mouse menu.
When the "Sample EJB Client Details" dialog appears, we take the defaults of connecting to embedded OC4J container. Clicking the (OK) button generates the following test class:
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.InitialContext;
import com.example.StatelessSampleEJB;
import com.example.StatelessSampleEJBHome;
public class SampleStatelessSampleEJBClient {
public static void main(String [] args) {
    SampleStatelessSampleEJBClient sampleStatelessSampleEJBClient =
       new SampleStatelessSampleEJBClient();
    try {
      Hashtable env = new Hashtable();
      env.put(Context.INITIAL_CONTEXT_FACTORY,
              "com.evermind.server.rmi.RMIInitialContextFactory");
      env.put(Context.SECURITY_PRINCIPAL, "admin");
      env.put(Context.SECURITY_CREDENTIALS, "welcome");
      env.put(Context.PROVIDER_URL,
              "ormi://localhost:23891/current-workspace-app");
      Context ctx = new InitialContext(env);
      StatelessSampleEJBHome statelessSampleEJBHome =
           (StatelessSampleEJBHome)ctx.lookup("StatelessSampleEJB");
      StatelessSampleEJB statelessSampleEJB;
      // Use one of the create() methods below to create a new instance
      // statelessSampleEJB = statelessSampleEJBHome.create();
      // Call any of the Remote methods below to access the EJB
      // statelessSampleEJB.createDepartment( int id, java.lang.String name, java.lang.String loc );
    catch(Throwable ex) {
      ex.printStackTrace();
}We uncomment the call to the create() method and add a few calls to the createDepartment() method so that the body of the test program now looks like this:
// Use one of the create() methods below to create a new instance
statelessSampleEJB = statelessSampleEJBHome.create();
// Call any of the Remote methods below to access the EJB
statelessSampleEJB.createDepartment( 13, "Test1","Loc1");
System.out.println("Created department 13");
statelessSampleEJB.createDepartment( 14, "Test2","Loc2");
System.out.println("Created department 14");
try {
// Try setting a department id that is too large!
statelessSampleEJB.createDepartment( 23456, "Test3","Loc3");
catch (AppException ax) {
System.err.println("AppException: "+ax.getMessage());
}Before we can successfully run our SampleStatelessSampleEJBClient we need to first run the EJB bean that the client will try to connect to. Since Oracle9i JDeveloper supports local running and debugging of the EJB-Tier without doing through a full J2EE deployment step, to accomplish this prerequisite step we just need to right-mouse on the StatelessSampleEJB node in the System Navigator and select "Run". This starts up the embedded OC4J instance and runs the EJB right out of the current out path.Finally, we can run the SampleStatelessSampleEJBClient, and see the output of the test program in the JDeveloper log window:
Created department 13
Created department 14
AppException: Error creating dept 23456
JBO-27010: Attribute set with value 23456 for Deptno in Dept has invalid precision/scale
Troubleshooting
One error that might arise while running the example is that the database connection information in your data-sources.xml for the jdbc/OracleCoreDS datasource does not correspond to the database you are trying to test against. If this happens, then double-check the file .\jdev\system\oc4j-config\data-sources.xml under the JDeveloper installation home directory to make sure that the url value provided is what you expect. For example, to work against a local Oracle database running on your current machine, listening on port 1521, with SID of ORCL, you would edit this file to have an entry like this for jdbc/OracleCoreDS :
<data-source
    class="com.evermind.sql.DriverManagerDataSource"
    name="OracleDS"
    location="jdbc/OracleCoreDS"
    xa-location="jdbc/xa/OracleXADS"
    ejb-location="jdbc/OracleDS"
    connection-driver="oracle.jdbc.driver.OracleDriver"
    username="scott"
    password="tiger"
    url="jdbc:oracle:thin:@localhost:1521:ORCL"
    inactivity-timeout="30"
/>This is the data-sources.xml file that gets used by the embedded OC4J instance running in JDeveloper.
Conclusion
Hopefully this article has illustrated that it is straightforward to utilize the full power of BC4J in local mode as part of your EJB Stateless Session Beans using container-managed transaction. This example illustrated a single createDepartment method in the enterprise bean, but by replicating the application module interaction code that we've illustrated in createDepartment, any number of methods in your stateless session bean can use the aggregated application module instance created in the ejbCreate() method.

Hi Steve, It4s me again;
About the question I made, I tried with a single assembly-descriptor tag and a single container-transaction tag in the deployment descriptor of the session bean and these were the results.
java.lang.NullPointerException
     void com.evermind.server.rmi.RMIConnection.EXCEPTION_ORIGINATES_FROM_THE_REMOTE_SERVER(java.lang.Throwable)
     java.lang.Object com.evermind.server.rmi.RMIConnection.invokeMethod(com.evermind.server.rmi.RMIContext, long, long, java.lang.reflect.Method, java.lang.Object[])
     java.lang.Object com.evermind.server.rmi.RemoteInvocationHandler.invoke(java.lang.Object, java.lang.reflect.Method, java.lang.Object[])
     java.lang.Object com.evermind.server.rmi.RecoverableRemoteInvocationHandler.invoke(java.lang.Object, java.lang.reflect.Method, java.lang.Object[])
     java.lang.Object com.evermind.server.ejb.StatelessSessionRemoteInvocationHandler.invoke(java.lang.Object, java.lang.reflect.Method, java.lang.Object[])
     void __Proxy1.modificaEnvoltura(java.lang.Integer, java.lang.Integer, java.lang.Integer, java.lang.Integer, java.lang.Integer, java.lang.Integer, java.lang.String)
     void SamplemdeController.envolturaControlEJBClient.main(java.lang.String[])
Then I tried with multiple assembly-descriptor tags each with a single container-transaction tag and the results were:
java.lang.NullPointerException
     void com.evermind.server.rmi.RMIConnection.EXCEPTION_ORIGINATES_FROM_THE_REMOTE_SERVER(java.lang.Throwable)
     java.lang.Object com.evermind.server.rmi.RMIConnection.invokeMethod(com.evermind.server.rmi.RMIContext, long, long, java.lang.reflect.Method, java.lang.Object[])

     void SamplemdeController.envolturaControlEJBClient.main(java.lang.String[])
Finally I tried with a single assembly-descriptor and multiple container tags and the results were:

How can I make my Stateless Session bean work out?

Issue in converting Struts view to JSF view using struts-faces integration

Hi All,
I am facing a issue in my Sruts to JSF conversion application using struts-faces.jar integration library.
Need expert's help desperately as I am not able to use <s:form> tag in my new jsf page to call a struts action.
I want to call a struts action from my web page designed using JSF,
but it seems impossible without using <s:form> tag from struts-faces integration library.
Please suggest how to resolve this...
I am using WSAD 5.1 IDE with inbuilt Test environment WebSphere server
JSF Version: Sun's RI 1.1
Struts framework: 1.2.6
Struts-Faces Integration Library version: 1.0
I have configured a controller element in struts-config.xml file as has been suggested by different online
documents I studied:
<controller>
<set-property property="processorClass"
value="org.apache.struts.faces.application.FacesRequestProcessor"/>
</controller>
But configuring a controller does not allow my test server to start up properly and due to errors the ActionServlet also becomes unavailable.
If I comment the controller and start the test server it starts fine but then I cannot access the converted jsf page which contains the <s:form action="/xxxxx.do"> tag.
If now I get back to <h:form> tag instead of <s:form> tag with a <h:commandButton action="xxxx.do"/> for form submission in my jsf page, I see the html page generated with all components but now checking the html source generated I see
<form action="/contextName/jspFolder/sameDisplayedPage.jsf"> which is not valid and never gets called successfully.
I think someways I need to use the <s:form> tag with the controller configured properly to use the struts-faces integration library's request processor, to get things working. But HOW???
Following is the error I get if I use the <controller> tag element in struts-config.xml file and start the server.
This error appears on starting the server without accessing any application's jsp web page

Error 503: Failed to load target servlet [ActionServlet] comes in web-browser
Following is the error which I get if I comment the <controller> element in the struts-config.xml file
and use a <s:form action="xxxxx.do"> in the struts converted jsf page. The web-server starts fine, but
accessing the jsf page givers error as:

Finally if I change my <s:form action="xxxxx.do"> tag to
<h:form>
<h:commandButton id="submit" action="xxxx.do" value="Submit" />
I see the webpage coming up in the browser (no controller element used in struts-config.xml file this time)
But in the html source of this html created from jsf I see
<form id="_id2" method="post" action="/training2/jsp/welcomeF.faces" enctype="application/x-www-form-urlencoded">
here form's action attribute is pointing to the same displayed page with the context name prefixed. I
assume it is because jsf could not resolve the "xxxx.do" action to anything so set it to the same displayed page.
May be I am wrong as usual...
Below is the simple struts jsp page which I need to convert to jsf page as I am converting only the View part of application.
I want to use the same struts beans and application logic at the back-end. At front-end I need UIComponents from JSF to be used.
Following is the struts jsp page
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1" %>
<%@ taglib prefix="html" uri="/WEB-INF/lib/struts-html.tld" %>
<%@ taglib prefix="bean" uri="/WEB-INF/lib/struts-bean.tld" %>
<html:html>
<html:base/>
<html:messages id="messages" />
<font style="color:red; font=weight:italic; font-family: century gothic">
<html:errors/>
</font>
<BODY>
<P>Sample Struts and JSF integration example</P>
<P>This one is being displayed via Struts specific tags</P>
<html:form action="validateUser.do">
<bean:message key="label.name" /> : <html:text property="name" />
<bean:message key="label.password" /> : <html:password property="password" />
<bean:message key="label.age" /> : <html:text property="age" />
<bean:message key="label.city" /> : <html:text property="city" />
<bean:message key="label.address" /> : <html:text property="address" />
<html:submit property="submit" value="Show info via Struts" />
</html:form>
</BODY>
</html:html>
I have converted it into the following jsf page
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://struts.apache.org/tags-faces" prefix="s" %>
<f:view>
<HTML><BODY>
<f:verbatim><P>Sample Struts and JSF integration example</P></f:verbatim>
<f:verbatim><P>This one is being displayed via JSF tags</P></f:verbatim>
<h:form> 
<h:inputText id="name" value="#{userForm.name}" /><f:verbatim>
</f:verbatim>
<h:inputSecret id="password" value="#{userForm.password}" /><f:verbatim>
</f:verbatim>
<h:inputText id="age" value="#{userForm.age}" /><f:verbatim>
</f:verbatim>
<h:inputText id="city" value="#{userForm.city}" /><f:verbatim>
</f:verbatim>
<h:inputText id="address" value="#{userForm.address}" /><f:verbatim>
</f:verbatim>
<h:commandButton id="submit" action="#{user.facesAction}" value="Show info via Struts" />
</h:form>
</BODY></HTML>
</f:view>

be extremely valuable to me. Anticipating a helping hand...

I've managed to get this working Ok from JDeveloper:

Basically you just have to fiddle around with Library settings to get this working OK.
As to how useful this is, well that's up to you - I'd not regard Faces + Struts as a must use combination, rather it's a can mix if you really need to. Look at Faces and Faces navigation first and see if that actually gives you enough before you start to look at mixing.

"Serious Problem in Struts" + "Please help me"

Hi all,
I m facing one problem in struts. I have A DTO with Attributes(data transfer Object) which contains one Array List. In that Arraylist i have other B DTO with Attributes.
In my Screen I have fields which are using some of the attributes from A DTo and B Dto
In the JSP
I m creating controls like this
<html:text name="facilityForm" property="dto.installationSite" />
in the ActionForm I m setting values which are typed in the screen to the dto.
I have to create one control(textbox) which is using B DTO Attribute..
How to do that?
if its the attribute of DTO i can create like this
"dto.installationSite"
But A Dto contains ArrayList that contains B Dto objects
<html:text name="facilityForm" property="dto.ARRAYLIST(B DTO).Attribute" />
Please help me...

try this... (not sure though)
<html:text name="facilityForm" property="dto[0].Attribute" />
or is it this:
<html:text name="facilityForm" property="dto(0).Attribute" />
... I'm not really sure about this, however. ...Maybe instead, loop thru the outer list and create a field for each object.
