Reload a jsf application from javaBean
hello
I am confused about reloading a jsf application from javaBean.
Could you explain it ?
regards
You can open a jsf page from any other application.
<form action="http://hostip:port/app/MyPage.jsf?key1=value1&key1=value1">
as we do in any other jsp page.
Now in JSF application, in MyPage.jsf write a scriptlet to get the parameters and from there you can use these params.
You can get a managed Bean reference in your jsp page. Here is the code for that.(ResultsInExcelBean is my managed bean.)
FacesContext fc = FacesContext.getCurrentInstance();
ResultsInExcelBean resultsInExcelBean = (ResultsInExcelBean)fc.getApplication().createValueBinding("#{ResultsInExcelBean}").getValue(fc);
Hope this helps you.

How to create JSF application from xsd files?
Hi,
We have many xsd files describing xml's which we are supposed to send to web services. Application which we are creating should allow user to fill xml documents with data and then we should send those xml files to some web service. We want to automatize as much as possible the process of application creation to avoid possible errors and to minimize our efforts (there are plenty of quite complex xsd files).
Our first approach was: we used Oracle JSXB to generate java classes basing on xsd files (using JDeveloper 10.1.3.2.0.4066). Then we tried to generate DataControls, but this action fails with following error:
Window title: Error in init bean
Message: Could not complete initbean because it would result in an invalid document
Details: oracle.bali.xml.model.XmlInvalidOnCommitException: SEVERE: Wartość atrybutu Name nie jest typu ID (Value of Name attribute is not of ID type)
Wartość musi być następującego typu: (Value must be of following type)
Nazwa typu: ID (Type name)
Typ pierwotny: string (Primitive type)
Z następującymi więzami: (With following constraints)
zgodne z wzorcem: [\i-[:]][\c-[:]]* (Compliant with template)
[ node = Name ]
<JavaBean version="10.1.3.40.66" id="XSLStylesheet" BeanClass="oracle.xml.xslt.XSLStylesheet" Package="oracle.xml.xslt" isJavaBased="true">
<Attribute Name="classMethodParams" IsUpdateable="0" Type="java.util.Hashtable" />
We tried Sun implementation fo JAXB - it generated different java classes (with annotation mechanism). Creation of DataControls using those classes was successful. Then we created simple JSF page and tried to put those DataControls on it in order to let the user fill it with data. The thing is that those controls are read only as there is no row created in those DC. We can't create any row in those DC as there are only 'commit' and 'rollback' operations. When we try to call 'CreateInsert' operation on child elements of those DC we get error in JDeveloper log window:
2007-05-29 10:08:46 oracle.adf.controller.faces.lifecycle.FacesPageLifecycle addMessage
WARNING: JBO-29000: DataControl:createRowData
2007-05-29 10:08:46 oracle.adf.controller.faces.lifecycle.FacesPageLifecycle addMessage
WARNING: DataControl:createRowData
new row is not created and controls are still read-only.
The question is:
1. is there another, more efficient way to create JSF application from xsd files?
2. if this is the best way to do it, what do we do wrong?
LeszekTo anyone who might find it useful: our solution to mentioned problem.
Few tips how to solve described problem:
1. Do not use JAXB (we checked Oracle and Sun)
2. Use castor http://www.castor.org/
a) for each xsd generate java files in separated package
b) use java 1.5 to let castor generate lists
c) use mapping of xml namespaces to java packages to have only 1 implementation of each xsd
3. Create facades - java files for you root-level java objects
4. Right click those facades and choose 'Create DataControl' in jdev
5. Now you may drag and drop you DataControls and use them in your JSF (or UIX) application
I hope it will help someone :)

Call a JSF application from a Standar Web application (JSP)
Hi all,
We have 2 aplication, one is JSF and the other one is standar web jsp.
We want to invoke from the standard web application to the JSF application and pass param from the jsp to the *.jsf page.
how can I do that?
Thanks.You can open a jsf page from any other application.
<form action="http://hostip:port/app/MyPage.jsf?key1=value1&key1=value1">
as we do in any other jsp page.
Now in JSF application, in MyPage.jsf write a scriptlet to get the parameters and from there you can use these params.
You can get a managed Bean reference in your jsp page. Here is the code for that.(ResultsInExcelBean is my managed bean.)
FacesContext fc = FacesContext.getCurrentInstance();
ResultsInExcelBean resultsInExcelBean = (ResultsInExcelBean)fc.getApplication().createValueBinding("#{ResultsInExcelBean}").getValue(fc);

The oracle version we are using is 11g.
Previously it worked fine when the application was used in 10g.
Can someone please help me in resolving this issue?

Are the the JDBC JARs packaged with the application? If so, remove the applicaiton packaged JDBC JARs as the JARs are also in WebSphere application server. -
JSF Application on WAS 6.1 when migrated from tomcat5.5 not loading
I'm migration a list of applications from Tomcat to WAS 6.1
I have a JSF application running on Tomcat 5.5.
The same application when hosting on websphere application server 6.1(latest service pack applied in 6.1.0.17 ) is not loading properly.
The application has a login screen that comes when loads. This comes fine in the tomcat server. But in the WAS this not loading. It's not giving any error messages also. What happens in WAS is in the login screen The header section will comes but the login fields ie the user Id and password section won't come.
I tried deploying the same war file from the Tomcat to the WAS server. Still there is no change.
Initially my WAS server version was 6.1.0.2, and then I had an issue with JSF servlet and context mappings.
After applying the fix pack 6.1.0.17 it was fine.
The application uses the a security filter- form based login in the web.xml
Is there any difference between the form base authentication between tomcat and websphere ?
Here is the section of web.xml for form based authentication
<!--Security filter - form based login -->
<filter>
<filter-name>Security Filter</filter-name>
<filter-class>org.securityfilter.filter.SecurityFilter</filter-class>

The same application is working on tomcat. So when we move it from tomcat to WAS should we change any settings.
if we are deploying the war file it should work in all the servers right?

Can you reload web application from the Weblogic console?
Good day, eh!
Can you reload all your jsp/servlet classes of your
web application from the Weblogic console?
A one big button labeled 'Reload application' would be very
good property in Weblogic
Thanks for Your answers

Hi,
I agree it is a much needed feature. Suppose I just change an init
param of one application in the web.xml, I don't want to take down the
15 other webapps running on my server just to be able to have that web
app restart and re-read is configuration. Of course, I could program
some servlet that allows changing application attributes and to enable
restarting, but really this a)does not cover all the cases (i.e. addind
an EBJ reference binding to web.xml) b) should be provided by the app
server, not programmed by every little programmer again & again.

How to call a stand alone java application from ADF BC JSP, struts or JSF
Hi,
My requirement is that there are utilities or stand alone java applications that I want to call from our existing applications.
We have two seperate applications one ADF BC Struts application we developed using JDeveloper 10.1.2 and another ADF BC JSF application we developed using JDeveloper 10.1.3.2.
We want to integrate applications like JTwain and others to help us in scanning. The application will be placed on the same server as our application. How can I do this without loosing all the current session information.
Please help.
Thanks and regards,There are two possible solutions.
First, if the tool or application you want to integrate, has an Java-API you can use this api and integrate the tool in your application (using one or more jars you add to the classpath).
Second, if the tool has no java api, you can call the tool via runtime.exec(...) as a shell process. This way you open a command shell in you application and execute the tool like you do on a normal command shell.
For tide integration and control I recommend the first approach. The second one is only for those tools which don't offer a java api.

Running Oracle Reports from JSF Application in Websphere Application Server
Hi everybody;
in our company we are developing jsf applications and we want to use our existing Oracle reports. Reports are deployed in Oracle Application Server 10G. Is there a way to call those reports from our jsf applications deployed in websphere application server.Calling reports is just constructing and submitting a URL. So constuct the url in your jsf app or create static hyperlinks in your jsf app to go to the needed url. The url should look something like:
http ://hostname:7777/reports/rwservlet?report=myrep.jsp&userid=scott/tiger@dev10g&desformat=html&destype=cache -

EJB 3.0 - 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 à 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 à 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. -

<h:outputText value="Last name"/>
<h:inputText

<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"%>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>User Listing</title>
</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}"
var="dataTableItem" border="1" cellpadding="2" cellspacing="2">

</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>

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.
EJB/JSF with ADF-binding tutorial:
http://www.oracle.com/technology/obe/obe1013jdev/10131/ejb_and_jpa/master-detail_pagewith_ejb.htm
EJB/JSF without ADF binding:
http://www.oracle.com/technology/obe/JavaEE_tutorial_10131/index.htm -
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"

<h:outputText value="Password" />
<h:inputSecret
id="Password"
value="#{user.user.password}"

<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>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>User Listing</title>
</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}"
var="dataTableItem" border="1" cellpadding="2" cellspacing="2">

</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>

</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.

URGENT: How to debug non-reproducable problem(s) in ADF JSF application?
This is one of the most anoying things in programing.... We have JSF application developed by JDev 10.1.3 and deployed on AS. It works fine but almost once or twice per day users complain that, say on a certain page (could be any page) they click on a button or a link and nothing happens. Sometimes it looks like the browser is trying to open a page but never does and sometimes the link or a button is dead. I looked into log file under opmn/logs and could not find anything?
This is very urgent, so please, please if you have any hint on how to approach this problem, let me know. At this time I cannot file the Service Request with Oracle since they would ask me to create sample code and reproduce the problem which is just not possible.
please help.Hi,
if you are on JDeveloper 10.1.3.0 then chances are that these are concurrency issues. If a user starts a long running query then others may be blocked by this. This is fixed in JSF RI that is contained in JDeveloper 10.1.3.1
Its just a guess. To prove my assumption, make sure you run the app with a single seat and see if the issue reproduces or exclude queries from the tests.

You'd need to put the right stuff in the url to make it work,
just like if
you were calling a page that's expecting GET params. I don't
really use the
HistoryManager, so you'll need to either look into this
yourself or ask
someone who knows more about it.

Deploying JSF application on Tomcat 5.0.28
Hi,
I am having problems deploying JSF application (developed using Studio Creator) on Tomcat. Any suggessions ....
HTTP Status 404 - Servlet Faces Servlet is not available....
Thanks in advanceI ran into this same problem moving from Tomcat 4.1.31 to Tomcat 5.0.28. This one was definitely a headscratcher, but the solution turned out to be simple as I had an older servlet api jar (2.3) in my J2SE's jre/lib/ext directory. I replaced the existing servlet.api with servlet-api.jar and jsp-api.jar from the Tomcat 5.0.28 common/lib directory, restarted Tomcat, and the problem disappeared.
