Ejb servlet application

i am using orion.
i have an ejb app running.. i can connect to it from an external client.
however, as soon as i turn the client into another ejb app that is just a servlet, i get ClassCastException when getting the remote interface.
any ideas?

i think it's due to the fact that your Home is not only in the classpath of the container but in the classpath of the servlet engine too. so when you're trying to get the home, a ClassCastException is thrown bcz the home you got has not the same version as the home in servlet engine (uid).
hope it helps.

How to deploy Servlet Application in Weblogic 8.1

Hi,
I am new to BEA Weblogic 8.1 .
I was trying to create a sample application using InelliJ IDea 5.1 , and IntelliJIdea 10.5 . i configured weblogic with IDE , but now i do not know how to deploy my application in weblogic .
I am new in IntelliJ also .
So Can anyone tell me how can i deploy a servlet application in any IDE like i also have eclipse indigo.
Thanks & Regards
Komi

Hi Komi
Basically you deploy your Servlet as a WAR File. I am not familiar with IntellJ IDE. But it should have a provision to export/create a WAR file that has your Servlet. Also I hope you already have web.xml file with 2 sections like this: First you mention full package of your servlet and give it a name. Then enter a mapping url. You will use this url to run your servlet like http://weblogichost:weblogicport/yourWebappcontextroot/myservlet
<servlet>
     <servlet-name>MyServlet</servlet-name>
     <servlet-class>com.abd.def.MyServlet</servlet-class>
</servlet>
<servlet-mapping>
     <servlet-name>MyServlet</servlet-name>
     <url-pattern>/myservlet</url-pattern>
</servlet-mapping>
Coming to deployment, I hope you already created a Weblogic Domain and have admin username/password. Start your domain. Login into weblogic console like http://host:port/console and use admin username/password. Then from Deployments section, deploy the above WAR file. In Weblogic you can deploy JAR (EJBs, java files), WAR (web jsp, html, webservices, servlets) or EAR (JAR + WAR). In your case its just a WAR file.
Refer the online docs for more details on Deployments in Weblogic.

EJB-JSF Application : Data does not persist to the database

Hi,
I am developing a JSF - EJB application and the data that I send from JSP Page through JSF Managed Bean --> Session Bean --> Java Persistence does not persist in database.
Here is my scenario ( Iam using JDeveloper IDE to create this application) -
SCENARIO START
The scenario consists of two web pages, one enlisting all the users stored in the database, the other contains a form for adding a user
1.) INDEX.JSP
2.) ADDUSER.JSP
Step 1: Create the USERS Table in database
CREATE TABLE users
user_id serial,
username varchar(255) NOT NULL,
first_name varchar(255),
last_name varchar(255),
password char(64) NOT NULL,
CONSTRAINT pk_users PRIMARY KEY (user_id)
Step 2: Add Database Connection To JDeveloper
Go to Database Connection Navigator and create a New Database Connection using the Wizard
Step 3: Create a New Application in JDeveloper and select JSF, EJB from Application Template
Step 4: ENTITY BEAN - In the EJB Node Right Click and Select EJB � New Entites from Table (JPA/EJB3.0)
Use The Wizard and create Entity Bean from Users Table which creates an Entity Bea POJO file as follows �
User.java -
package lux.domain;
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.NamedQuery;
import javax.persistence.SequenceGenerator;
import javax.persistence.Table;
@Entity
@NamedQuery(name = "User.findAll", query = "select o from User o")
@Table(name = "USERS")
public class User implements Serializable {
@Column(name="FIRST_NAME")
private String firstName;
@Column(name="LAST_NAME")
private String lastName;
@Column(nullable = false)
private String password;
@Column(nullable = false)
private String username;
@Id
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="users_seq_generator")
@SequenceGenerator(name="users_seq_generator", sequenceName="users_user_id_seq")
@Column(name="USER_ID", nullable = false)
private Long userId;
public User() {
public String getFirstName() {
return firstName;
public void setFirstName(String firstName) {
this.firstName = firstName;
public String getLastName() {
return lastName;
public void setLastName(String lastName) {
this.lastName = lastName;
public String getPassword() {
return password;
public void setPassword(String password) {
this.password = password;
public String getUsername() {
return username;
public void setUsername(String username) {
this.username = username;
public Long getUserId() {
return userId;
public void setUserId(Long userId) {
this.userId = userId;
Step 5: STATELESS SESSION BEAN - In the EJB Node Right Click and Select EJB � New Entites from Table (JPA/EJB3.0)
Again Right Click on Model and create Session Bean from Wizard which creates two files �
UserDAOBean.java � Stateless Session Bean
UserDAO.java � Local Interface
package lux.facade;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import java.util.List;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import javax.persistence.Query;
import lux.domain.User;
@Stateless(name="UserDAO")
public class UserDAOBean implements UserDAO {
@PersistenceContext(unitName="Model")
private EntityManager em;
public UserDAOBean() {
public User getUser(int UserId) {
User u = new User();
u = em.find(User.class, UserId);
return u;
public List<User> getAllUsers() {
Query q = em.createQuery("SELECT u FROM User u");
List<User> users = q.getResultList();
return users;
public void createUser(User u) {
String hashedPw = hashPassword(u.getPassword());
u.setPassword(hashedPw);
em.persist(u);
public void updateUser(User u) {
String hashedPw = hashPassword(u.getPassword());
u.setPassword(hashedPw);
em.merge(u);
public void deleteUser(User u) {
em.remove(u);
private String hashPassword(String password) {
StringBuilder sb = new StringBuilder();
try {
MessageDigest messageDigest = MessageDigest.getInstance("SHA");
byte[] bs;
bs = messageDigest.digest(password.getBytes());
for (int i = 0; i < bs.length; i++) {
String hexVal = Integer.toHexString(0xFF & bs);
if (hexVal.length() == 1) {
sb.append("0");
sb.append(hexVal);
} catch (NoSuchAlgorithmException ex) {
Logger.getLogger(UserDAOBean.class.getName()).log(Level.SEVERE, null, ex);
return sb.toString();
Step 6: Create a Deployment file in the Model and Deploy this to a JAR file
Step 7: Now Right Click on View/Controller Node and create a Java File �
UserController.java -
package lux.controllers;
import javax.ejb.EJB;
import javax.faces.model.DataModel;
import javax.faces.model.ListDataModel;
import lux.domain.User;
import lux.facade.UserDAO;
public class UserController {
@EJB UserDAO userDao;
private User user;
private DataModel model;
public String createUser() {
this.user = new User();
return "create_new_user";
public String saveUser() {
String r = "success";
try {
userDao.createUser(user);
} catch (Exception e) {
e.printStackTrace();
r = "failed";
return r;
public DataModel getUsers() {
model = new ListDataModel(userDao.getAllUsers());
return model;
public User getUser() {
return user;
public void setUser(User user) {
this.user = user;
Step 8: Configure page flow in faces-config.xml
1. Create the JSP file adduser.jsp by right-clicking View-Controller
node and selecting New > JSP. Use the wizard to create JSF � JSP Page, fill in
File Name adduser.jsp, click Finish. -
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<%@taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">

<f:view>
<h:form>
<h:messages/>
<h:panelGrid columns="2">
<h:outputText value="Username"/>
<h:inputText

value="#{user.user.username}"
required="true"/>
<h:outputText value="First name"/>
<h:inputText
id="FirstName"
value="#{user.user.firstName}" />
<h:outputText value="Last name"/>
<h:inputText
id="LastName"
value="#{user.user.lastName}" />
<h:outputText value="Password" />
<h:inputSecret
id="Password"
value="#{user.user.password}"
required="true" />
<h:panelGroup/>
<h:commandButton
action="#{user.saveUser}"
value="Save"/>
</h:panelGrid>
</h:form>
</f:view>
</body>
</html>
2. Repeat the previous step for another JSP file failed.jsp.
3. On failed.jsp add the string
Save failed
Next we configure the page flow.
1. Open faces-config.xml.
2. Create index.jsp -
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<%@taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

</head>
<body>
<f:view>
<h:form>
<h:outputText value="User Listing"/>
<h:commandLink action="#{user.createUser}" value="Create a user"/>
<h:dataTable value="#{user.user}"

</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="First name"/>
</f:facet>
<h:outputText value="#{dataTableItem.firstName}" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Last name"/>
</f:facet>
<h:outputText value="#{dataTableItem.lastName}" />
</h:column>
</h:dataTable>
</h:form>
</f:view>
</body>
</html>
3. Drag an arrow from index.jsp to adduser.jsp and replace the arrow�s label to create_new_user.
4. Repeat the previous step for failed, by dragging and arrow from adduser.jsp to failed.jsp renaming the label to f
ailed
5. Finally repeat the step for adduser.jsp, by dragging from adduser.jsp to index.jsp renaming the label to success.
This creates the following faces-config.xml file �
<?xml version='1.0' encoding='UTF-8'?>
<faces-config>
<managed-bean>
<managed-bean-name>user</managed-bean-name>
<managed-bean-class>lux.controllers.UserController</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
<managed-property>
<property-name>username</property-name>
<value>#{username}</value>
</managed-property>
<managed-property>
<property-name>firstName</property-name>
<value>#{firstName}</value>
</managed-property>
<managed-property>
<property-name>lastName</property-name>
<value>#{lastName}</value>
</managed-property>
<managed-property>
<property-name>password</property-name>
<value>#{password}</value>
</managed-property>
</managed-bean>
<navigation-rule>
<from-view-id>/index.jsp</from-view-id>
<navigation-case>
<from-outcome>create_new_user</from-outcome>
<to-view-id>/adduser.jsp</to-view-id>
</navigation-case>
</navigation-rule>
<navigation-rule>
<from-view-id>/adduser.jsp</from-view-id>
<navigation-case>
<from-outcome>failed</from-outcome>

</navigation-case>
<navigation-case>
<from-outcome>success</from-outcome>
<to-view-id>/index.jsp</to-view-id>
</navigation-case>
</navigation-rule>
</faces-config>
Step 9: Create a Deployment file in the View-Controller and Deploy this to a WAR file
Step 10: Create a Deployment file in the View-Controller and create an EAR file and add Model�s JAR and View-Controller�s
WAR files to it.
Step 11: Run the JSP Files
SCENARIO END
Now, When I execute Index.jsp, it does not list values from database and when I click on Create User link, it takes me to adduser.jsp page. When I fill values in this page and click Save button, it takes me to Save Failed page and data does not persist to the database.
WHAT IS WRONG OUT HERE ???

If you set a breakpoint in your createUser method - does this code get executed?
We have a couple of tutorials that might show you how to do this.

1. You are using a memory tool and are incorrectly reading the results.
2. You are using JNI or using a third party JNI which uses an unusual system resource and that is not cleaning up that resource.
3. One very unusual case, you have a log file (or some other file) which is being posted into the same place in the file system as the OS swap space. When that happens the "memory" fills up.

Unable to Create EJB Test Application ....

Folks - I realize that I need to have my EJB offer remote interfaces in order to be able to setup an EJB Test Application from within SJSE6 - but nonetheless, the option is uanvailble off the main menu for logical Session Bean node -
Any thoughts ?
John Schmitt

Hi,
in order to generate the test app, you have to create a J2EE application and add the beans to it using the explorer, than the option should be enabled.
Also it is much better that you use Studio to create the beans and all of the components of the application. Do not create the beans by hand, the IDE will create all of the interfaces for you automatically when you use it to create the beans.

Business Intelligence -- Servlet Application

Hello
I have created Business Intelligence --> Designer and then
I have created Servlet Application through
New --> Business Intelligence --> Servlet Application
It working fine and runs with url
http://192.168.1.237:8988/dw-dw_proj-context-root/mypackage1.BIController1
I want to define a alias for it i.e.
user can access it with the url
http://dwapp/ {How to define such alias?}
I want to make different tiers how to do that i m new so plz guide me

Have your application been deployed to an application server? If yes, you can define a virtual root to point to the url of the servlet application. If no, you may want to create a page that redirects the user to the servlet application.
Thanks

I unable to run ejb with application client using oc4j j2ee container

Hi,
I have installe oracle9i (1.0.2.2) oc4j j2ee container.
I unable to run the ejbs . please help me how to run ejbs with application client and which files are shall configure.

//env.put(Context.SECURITY_PRINCIPAL, "guest");
//env.put(Context.SECURITY_CREDENTIALS, "welcome");
//Context ic = new InitialContext (env);
System.out.println("\nBegin statelesssession DemoClient.\n");
Context context = new InitialContext();
Object homeObject = context.lookup("java:comp/env/DemoApplication");
DemoHome home= (DemoHome)PortableRemoteObject.narrow(homeObject, DemoHome.class);
System.out.println("Creating Demo\n");
Demo demo = home.create();
System.out.println("The result of demoSelect() is.. " +demo.sayHello());
}catch ( Exception e )
System.out.println("::::::Error:::::: ");
e.printStackTrace();
System.out.println("End DemoClient....\n");
When I am running client application I got this type of Exception

Please give me your valuable suggestions. Which are shall i configure .
Thanks & Regards,
Badri

Hi Badri,
ApplicationClientInitialContextFactory is for clients which got deployed inside OC4J container..
For looking up EJB from a stand alone java client please use RMIInitialContextFactory..So please change ur code....
Also please check ur server.xml
Since you have specified your ejb domain as "sampledemo"
you have to use that domian only for look up..But it seems that you are looking up for "Demo" domain instead of "sampledemo" domain...So change your code to reflect that..
Code snippet for the same is :
Hashtable env = new Hashtable();
env.put("java.naming.provider.url", "ormi://localhost/sampledemo");
env.put("java.naming.factory.initial", "om.evermind.server.rmi.RMIInitialContextFactory");
env.put(Context.SECURITY_PRINCIPAL, "guest");
env.put(Context.SECURITY_CREDENTIALS, "welcome");
Context ic = new InitialContext (env);
Hope this helps

Is it possible to include JSF into JSP-Servlet application?

I have an existing JSP-servlet application. I am wondering if it is OK to add new pages to this application in form of JSF?
Thanks

Just learn JSF and it will all be clear.
They can perfectly co-exist and you can perfectly link or redirect from one to other (plain GET requests), you can perfectly share the same session and application scoped attributes, but for POST requests (forms submits) from JSP to JSF or vice verse you just need to understand how the one handles/expects the request parameters and that kind of stuff.

CLASSPATH to r:\\dealershop\\WEB-INF\\classes.

Hi,
I developed a JSP/servlet test application that makes
use of kodo 2.2.3 STANDARD EDITION for its persitence.
I successfully compile and annotate the application.
I am also able to successfully generate the db
schema with schematool.
Unfortunately, when I run the application using
Resin 2.0.2, Kodo is unable to initialize properly.
Initially it was not able to find \"system.prefs\" file.
I fixed that by putting \"system.prefs\" in WEB-INF\\classes.
Unfortunately, Kodo is still unable to initialize and
gives the following message:
The system could not initialize; the following registered
persistent types are missing metadata
or have not been enhanced:
[class com.dpov.purchaseorder.PurchaseOrder,
class com.dpov.catalog.Product,
class com.dpov.uidgen.counter.Counter,
class com.dpov.catalog.dao.jdo.CategoryHierarchyEntry,

class com.dpov.catalog.Category,
class com.dpov.lineitem.LineItem,
class com.dpov.dealer.Dealer,
class com.dpov.user.User,
class com.dpov.customer.Customer].
I use \"system.jdo\" to describe metadata for the enhancer.
I tried to put it both in WEB-INF\\lib and WEB-INF\\classes but
it still fails.
Please note that:
1) my classpath variable is not set
2) my application\'s class file are in WEB-INF\\classes
3) kodo jars are in WEB-INF\\lib
4) mysql jdbc driver is in WEB-INF\\lib
5) system.prefs is in WEB-INF\\classes
6) system.jdo is in WEB-INF\\classes
Thanks in advance,

How to run JSP/Servlet applications on Apache?

As we all know that tomcat is an JSP/Servlet engine. Apache is a web server not a JSP/Servlet enabled web server. Then in order to run JSP/Servlet applications on Apache web server on unix, what should I do?
Thanks.
James Liu

Can you give me some detailed information about how to combine Apache and Tomcat? Note, the application is going to run on Sun Solaris Operating System.
By the way, where do you put your final version of application? on windows or on Unix? on tomcat or on apache?
I am building the application using tomcat on windows, but now I almost finished the application, so I decide to move it to Unix which uses apache as the web server. But I got problems, the Servlet engine (JServ) can not understand "RequestDispatcher" (an object used to redirect jsp pages).
Help please.

Can an EJB client application access to EJBs on two domains concurrently?

It is well-known that there can be multiple domains in a SUN application server. If two domains are started up, can the same EJB client application call different EJB methods from the two domains? If can, how to implement? Please kindly give a snippet of sample codes.
Another question: can EJBs among multiple domains communicate with each other? If can, tell me how to implement and had better provide some sample codes as well.

I have my client working now!
I was looking around on other forums and found a guy who said that javax.comm has problems with security. here is the address
http://lists.dalsemi.com/maillists/java-powered-ibutton/2002-February/002168.html
He said,
"This is an error generated by the javax.comm packages when initializing
the
serial ports. It's basically a security related bug. Officially, all
packages stored in your lib/ext folder should be considered trusted
code,
running with the same permissions as your trusted main application. But
it
seems that isn't the case with comm.jar.
I've heard that signing the comm.jar file might fix it, but I wasn't
able to
verify that myself (but I didn't test with Netscape's java plugin). I
found
a workaround that should take care of it (as long as your main
application
has "all-permissions"). Try adding this line to the top of your main
method:
System.setSecurityManager(null);
So I did that and it worked except for one thing. at the end of my program the client tells me
The system cannot find the path specified.
Do you think this is a major problem? What is it trying to find??

Need to restrict access to multiple servlet applications on same box

Hi!
I have deployed two separate servlet applications to the same IAS. I need
to restrict access to each application - that is requests from one source
should only have access to one application and not the other. The web
server we are using is IIS.
Should I create a separate IAS to deploy the second application to? Can I
restrict based on IP - that is port 80 is reserved to application 1 while
port 81 is restricted to application 2? If so, how do I go about this? It
appears that the web connector only receives on one port (default 80).
Any help would be greatly appreciated.
Sheila

I see. So do you mean that I can override the port number in the proxy startup script itself? I can try doing that and see if it works fine.
About Coherence 3.7, yes. I did see that it has some cool features about proxy discovery. But at this point I am stuck at using 3.6 and 3.6.1.

Problem with iWay Servlet Application Explorer

Hello Everyone,
I have installed the iWay SWIFT adapter. Now I am trying to configure the iWay Servlet Application Explorer. I have deployed the iwae.ear after making necessary changes as suggested. But the problem is when I am trying to open the Servlet Application Explorer at http://<XI host:port>/iwae/index.html, the page opens but it is not showing the available adapters and in the right pane it is giving following error:
<b>Unable to Retrieve Information
The underlying connection was closed: Unable to connect to the remote server. Check your configuration or try to connect later</b>
Has anyone faced any similar problem earlier, if so how to solve this issue.
I have used the following values for service line in the web.xml inside the iwae.war.
<service displayName="localhost" url="http://localhost:50100/"/>
<service displayName="jca" provider="com.ibi.adapter.jspae.CustomJCAIWAEConnection" url="c:\program files\iway55#base" />
(Where 50100 is the j2EE port on our XI server.)
Any tip regarding this is highly appreciated.
Thanks
Abinash
