Boolean in a bean

I have a bean which has a method called isValid() this method returns either true or false.
public class MyBean{
//other methods here.............
public boolean isValid(){
                //...SQL STATEMENT
          if(result.next())
               return true;
               return false;
}in my JSP page if the method returns false I want to write:
"Incorrect information entered"
but if it's true it will say:
"Information is correct"
I know how to get properties using the <jsp:getProperty... />
but not how to get a return value from a method.
how can I do this in my JSP page?
Thanks for any help

yes, but what is the tag for it:
<jsp:useBean id="test" class="myPackage.MyBean" />
<jsp:getProperty name="test" Property="What goes here??" />
Thanks for your help

IsDirty or isModified flag for Entity Beans

I've been reading a lot of conflicting information on the use of a isModified boolean in Entity Beans. Is creating a modified boolean recommended for BMPs? Or CMPs? Or both? I am doing a BMP, and wondering if it will really buy me much performance-wise to add this logic to my ejbStore() method. Thoughts?
Thanks,

Greetings,
I've been reading a lot of conflicting information on
the use of a isModified boolean in Entity Beans. IsAre you sure all this information was presented in the same contexts? I'm guesing the apparent conflict was only perceptual and without regard for BMP in one case and CMP in [the /an]other...
creating a modified boolean recommended for BMPs? OrDefinitely! The container will call your bean's ejbStore method (sometime) after a call to its business method(s) to ensure its state is synchronized back to the resource. However, in a BMP bean, the container has no way of knowing whether the business method(s) actually modified your bean's state, making the call to ejbStore a "blind call". Additionally, business method calls are not the only triggers to calling ejbStore - transaction COMMIT (regardless if your bean was an active participant in the transaction), and passivation being among them, as well as "at any time within the container's discretion". Though, precisely when and how often the spec. leaves to the "vendor's disrection". With all these factors at play, "blindly" hitting the resource is a sure-fire way to degrade the performance of your beans and, consequently, the application(s) which they are a part. Make your synchronization code "smart" - use a 'dirty flag'.
CMPs? Or both? I am doing a BMP, and wondering if itIn CMP, the container has more direct knowledge of the bean's state fields and, therefore, should know whether an actual update to the resource is needed - this is especially true for EJB 2.0. Of course, this depends on the vendor's implementation (coders) to be "smart" on the bean coder's behalf. In any event, the container has absolute control over bean synchronization, and ejbStore is relegated to being a pre-processor, in CMP, so using a 'dirty flag' here will gain you absolutely nothing!
will really buy me much performance-wise to add this
logic to my ejbStore() method. Thoughts?Refer back to the above. :)

Can't update in mysql

I am using JSP and MYSQL with a bean that does my database work.

Couple of pointers.
1 - use [ code ] tags to post code
2 - that is WAY too much code for more than a cursory glance. You're lucky the problem was easy to spot.
Your problem lies in your edit JSP form:
<td>Product Name:</td>
<td><input name="description" type="text" value="<jsp:getProperty name="inventoryBean" property="item" />"></td>Note that the name of the input field is different from the jsp property you are populating it with.
In fact, all of your input fields have a name of "description"
I would recommend on your inventory_admin.jsp page that you put the following debugging code to make sure that the parameter values come through and are set correctly.
out.println("name = param: " + request.getParameter("name") + "bean = " + inventoryBean.getName() + "<BR>");
out.println("description = param:" + request.getParameter("description") + "bean = " + inventoryBean.getDescription() + "<BR>");

I ve declared
<form-property name="file"
type="org.apache.struts.upload.FormFile"/>
in struts-config file and
<field property="file"
depends="imagefile">
in validate file.
Thanks

I ve solved like this

Please anybody help me

Generic equality check

Since the equals method is not generic we have to provide the object override, correct?
public boolean equals( Magic bean ) // NO GOOD!

.equals defines a total relation on all objects.
If two objects don't have the same type, they
are inequal. No type safety issue here.
This is different than Comparable.compareTo.
This method defines a partial order since some
kinds of objects can't be ordered. For example, there
is no natural ordering on complex numbers.
Thus is makes no sense to compare 1 to i.
This is why Number doesn't implement
Comparable and why Comparable is parameterized.

What is the better way to open and close connection in bean

Hello, may i ask about the best way to open and close the connection?
At the first, the connection code is store in Conn class bean. The JSP page will call a method in Process bean to process the query and update of database. the Process bean is using th Conn to connect to database.
In my process bean, it have a method for each type of sql like select, insert, update, and delete for each tables. Each method will call the Conn to open and close the connection. The jsp page can simply call a method retrieve or update records.
However, when calling the processUpdate method, it is a method that update a group of tables base on the query result of another group of tables and calculation. If I calling the query method in the same bean file, it will open and close the connection many times (more than 1000 times). After open and close the connection several times, the connection to mySQL will be fail.
Currently, i include 2 method in Process that is only calling the Conn to open the connection and close connection. When calling the openConnection method, it will also set the boolean connected in the class to true and call Conn to open connection. When calling the closeConnection method, it will also set the boolean connected in the class to false and call Conn to close connection.
After that, i add some change to the query method which is when the connected is false, it will open the connection by calling the Conn and close the connection themself. If the connected is true, it will not call the Conn to open and close the connection because it already connected to the database.
Now, i when i calling the query method in jsp, it can open the connection and close the connection individually. When i call the processUpdate in the jsp, this method will calling the openConnection before calling the query and calling closeConnection at the end. It not only faster the process(less open and close), it also no cause the connect to mySQL fail error again. However, it also make the coding in the bean file more longer and complex.
Is there have any better solution?

Use connection pooling. This will put the connection management in the hands of the webserver, not your code. Check out this post:

Can't Create Bean Error

I modified the numguess example that comes with tomcat but I get a "can't create bean" error message when I call my jsp file. If anyone can see what I'm doing wrong or suggest ways to discover the problem I'd appreciate it.
My modified jsp:

<%@ page import = "num.NumberGuessBean" %>
<jsp:useBean id="numguess" class="num.NumberGuessBean" scope="session"/>
<jsp:setProperty name="numguess" property="*"/>
<html>
<head><title>Number Guess</title></head>
<body bgcolor="white">
<font size=4>
<% if (numguess.getSuccess()) { %>
Congratulations! You got it.
And after just <%= numguess.getNumGuesses() %> tries.<p>
<% numguess.reset(); %>
Care to try again?
<% } else if (numguess.getNumGuesses() == 0) { %>
Welcome to the Number Guess game.<p>
Play with default limits ( a number between 0 and 100)<p>
or enter upper and lower limits.<p>
<form method=get>
Play with defaults?: <input type=radio name=default value="yes">Yes
<input type=radio name=default value="no">No
<\form>
<% if (numguess.getRadio().equals("no")) { %>
<form method=get>
Enter upper limit:<input type=text name=upperLimit>
Enter lower limit:<input type=text name=lowerLimit>
<\form>
<% numguess.reset(); %>
<% } %>
<form method=get>
What's your guess? <input type=text name=guess>
<input type=submit value="Submit">
</form>
<% } else { %>
Good guess, but nope. Try <b><%= numguess.getHint() %></b>.
You have made <%= numguess.getNumGuesses() %> guesses.<p>
I'm thinking of a number between <jsp:getProperty name="numguess" property="lowerLimit"/> and <jsp:getProperty name="numguess" property="upperLimit"/>.<p>
<form method=get>
What's your guess? <input type=text name=guess>
<input type=submit value="Submit">
</form>
<% } %>

Enable/Disable Column in a Advanced Bean Table

Hi,
I have 2 columns that needs to be enabled/disabled on a standard oa page PO Lines summary page.
I went through couple of blogs/forums and found 2 approaches :-
Approach 1
1) Extended the standard VO POLinesMerge.
2) Added a attribute column DeriveDisplayFlag of type VARCHAR2 . This call a database function and will return Y or N
3) Added a attribute of type ShowAdditionalColumn boolean. the get method of this attribute returns TRUE if DeriveDisplayFlag is 'Y' otherwise returns FALSE.
4) created a substitution for the custom VO
5) uploaded the substitution to mds.
6) copied the xml/class files to $JAVA_TOP/..
7) Bounced entire middle tier
8) using personalization, entered a SPEL command on the rendered property. I know rendered will hide/show the column but for time being I just want this to work.
But this fails :-
oracle.apps.fnd.framework.OAException: Message not found. Application: FND, Message Name: FND_VIEWOBJECT_NOT_FOUND. Tokens: VONAME = XXPBPoLinesMergeVO; APPLICATION_MODULE = oracle.apps.po.document.server.DocumentAM;
I am not aware how to get around this. Can someone help please?
Approach 2
1) steps 1 to 6 from Approach 1.
2) trying to extend controller class OrderLinesTableRNCO. But have couple of questions. This iis a advanced bean table so how should i reference individual record and the column that i need to disable/enable ?
Conceptual questions
Also, when i am entering a new record at what point in time the 2 new attribute will derive its value? the 2 attributes are dependent on the Item number column but i have not created a dependency between the attributes and Item# column.
Will the controller logic fire for every column while i am entering a new record?
Thanks.

Hi Anil,
Thanks for the response. I have given up that i will get reply on this post.
I have done the substitution and upload the jpx to umsing importer.
But you are correct may be i might have done something wrong. Can you please help me. I can send you the files if you can review and let me know it will be great.
Also, will this approach work since PO Lines is a advanced bean table ?
One of the experts suggested to use Bound values. I am not sure how to implement it though?
I have went and told back to my business team that I am not able to do this so now they have asked me to enable/disable columns based on a dff value on po header. I thought this will be easier by extending the controller class on PO Lines table but that too is not working.
Can you help me please ?
Here is my code to extend the controller class :-
package xxpb.oracle.apps.po.webui;
import oracle.apps.fnd.common.VersionInfo;
import oracle.apps.fnd.framework.webui.OAControllerImpl;
import oracle.apps.fnd.framework.webui.OAPageContext;
import oracle.apps.fnd.framework.webui.beans.OAWebBean;
import oracle.apps.fnd.framework.webui.beans.message.OAMessageLovInputBean;
import oracle.apps.fnd.framework.webui.beans.message.OAMessageTextInputBean;
import oracle.apps.fnd.framework.webui.beans.table.OAAdvancedTableBean;
import oracle.apps.fnd.framework.webui.beans.table.OAColumnBean;
import oracle.apps.fnd.framework.webui.beans.table.OASortableHeaderBean;
import oracle.apps.fnd.framework.webui.beans.table.OATableBean;
import oracle.apps.po.document.order.webui.OrderLinesTableRNCO;
public class XXPBOrderLinesTableRNCO extends OrderLinesTableRNCO
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
super.processRequest(pageContext, webBean);
OAAdvancedTableBean tableBean =
(OAAdvancedTableBean)webBean.findIndexedChildRecursive("LinesTableRN");
OAMessageLovInputBean poLineLov =
(OAMessageLovInputBean)tableBean.findIndexedChildRecursive("XXPBSecondaryUOMLOV");
poLineLov.setDisabled(false);
}

Noob Question: Problem with Persistence in First Entity Bean

Hey folks,
I have started with EJB3 just recently. After reading several books on the topic I finally started programming myself. I wanted to develop a little application for getting a feeling of the technology. So what I did is to create a AppClient, which calls a Stateless Session Bean. This Stateless Bean then adds an Entity to the Database. For doing this I use Netbeans 6.5 and the integrated glassfish. The problem I am facing is, that the mapping somehow doesnt work, but I have no clue why it doesn't work. I just get an EJBException.
I would be very thankfull if you guys could help me out of this. And don't forget this is my first ejb project - i might need a very detailed answer ... I know - noobs can be a real ....
So here is the code of the application. I have a few methods to do some extra work there, you can ignore them, there are of no use at the moment. All that is really implemented is testConnection() and testAddCompany(). The testconnection() Methode works pretty fine, but when it comes to the testAddCompany I get into problems.
Edit:As I found out just now, there is the possibility of Netbeans to add a Facade pattern to an Entity bean. If I use this, everythings fine and it works out to be perfect, however I am still curious, why the approach without the given classes by netbeans it doesn't work.
public class Main {
    private EntryRemote entryPoint = null;
    public static void main(String[] args) throws NamingException {
        Main main = new Main();
        main.runApplication();
    private void runApplication()throws NamingException{
        this.getContext();
        this.testConnection();
        this.testAddCompany();
        this.testAddShipmentAddress(1);
        this.testAddBillingAddress(1);
        this.testAddEmployee(1);
        this.addBankAccount(1);
    private void getContext() throws NamingException{
        InitialContext ctx = new InitialContext();
        this.entryPoint = (EntryRemote) ctx.lookup("Entry#ejb.EntryRemote");
    private void testConnection()
        System.err.println("Can Bean Entry be reached: " + entryPoint.isAlive());
    private void testAddCompany(){
        Company company = new Company();
        company.setName("JavaFreaks");
        entryPoint.addCompany(company);
        System.err.println("JavaFreaks has been placed in the db");
    }Here is the Stateless Session Bean. I added the PersistenceContext, and its also mapped in the persistence.xml file, however here the trouble starts.
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
@Stateless(mappedName="Entry")
public class EntryBean implements EntryRemote {
    @PersistenceContext(unitName="PersistenceUnit") private EntityManager manager;
    public boolean isAlive() {
        return true;
    public boolean addCompany(Company company) {
        manager.persist(company);
        return true;
    public boolean addShipmentAddress(long companyId) {
        return false;
    public boolean addBillingAddress(long companyId) {
        return false;
    public boolean addEmployee(long companyId) {
        return false;
    public boolean addBankAccount(long companyId) {
        return false;
}That you guys and gals will have a complete overview of whats really going on, here is the Entity as well.
package ejb;
import java.io.Serializable;
import javax.persistence.*;
@Entity
@Table(name="COMPANY")
public class Company implements Serializable {
    private static final long serialVersionUID = 1L;
    @Id

    private String name;
    public Long getId() {
        return id;
    public void setId(Long id) {
        this.id = id;
   public String getName() {
        return name;
    public void setName(String name) {
        this.name = name;
        System.err.println("SUCCESS: CompanyName SET");
    @Override
    public int hashCode() {
        int hash = 0;
        hash += (id != null ? id.hashCode() : 0);
        return hash;

        if ((this.id == null && other.id != null) || (this.id != null && !this.id.equals(other.id))) {
            return false;
        return true;

Edited by: Taggert_77 on Jun 8, 2009 2:27 PM

Well I don't understand this. If Netbeans created a Stateless Session Bean as a facade then it works -and it is implemented as a CMP, not as a BMP as you suggested.
I defenitely will try you suggestion, just for curiosity and to learn the technology, however I dont have see why BMP will work and CMP won't.
I also don't see why a stateless bean can not be a CMP. As far as I read it should not matter. Also on the link you sent me, I can't see anything related to that.
Maybe you can help me answering these questions.
I hope the above lines don't sound harsh. I really appreciate your input.
Best regards

How to call a bean from a form?

hi all
i want to write a simple bean that checks the login information (userId ad Password) passed to it by a form in my jsp file.
so i think i have to call the setUser() and setPassword() methods of my bean in a single action... how to do it?
I also thought i can do it by calling a JavaScript, by I dont know how....
then, once i get the boolean value (logged) returned from my bean, i can (through jsp) redirect the logged user to another page, or send a message to the non-logged user.
is it a good solution or should I do it with a servlet?
thanx for your answers
sandro

u can do it using a servlet or JSP itself. Check the sample code below to see how u can validate using values from form
<%
String username=request.getString("frmUser");
String password=request.getString("frmPassword");
urBean userBean = new urBean(); //Creating instance of ur bean class.
userBean.setUserName(username); //Setting username
userBean.setPassword(password); //Setting password
boolean flag = userBean.validate(); //This functions validates against a database.
if(flag) {
response.sendRedirect("loggedin.jsp"); //redirects to page on successfull login
}else{
response.sendRedirect("error.jsp"); //redirects to error page.
%>
Hope this helps

JSP File:
<%@ page import="sax.*,java.io.*,java.util.*,java.lang.*,java.text.*;" %>
<jsp:useBean id="p" class="sax.ReadAtts"/>
Data after Parsing is.....
<%=p.parse"E:/Log.xml","/acq/service/metrics/system/stackUsage")%>
Expected Output:
The jsp file should print all the vector objects from the "ReadAtts" bean
Actual Output:
Data after Parsing.......[]

Error connecting to bi bean catalog with jdev

I'm in the process of getting the bibdemo up and running.
Started with oracle 9ir2 and applied the patch set 1 as directed by the bib903 installation instructions. After installtion of bib903 ran catalog creation scripts without any errors. Installed the bibdemo (latest) without any errors as well.
Started up jdeveloper....
While testing my connection to the bi bean catalog I get
an error telling me that the connection was successful but the metadata is not valid and could not be retrieved.
As far as I can tell, everything is valid. I went ahead and copied the jdbc drives from oracle_home/jdbc/* from the database into the jdev/jdbc/home.. Also i removed the olap api 901 jar from the 'available library list'
Neither things seem to make a difference...
TIA...

Hi
As part of your patching process did you run the sql module CATPATCH.SQL? If not please refer to the patch note instructions for details on how to apply this patch. This patch must be fully applied for BI Beans 9.0.3 to work correctly.
Also please check that olap_api_92.jar is in the JDEV_HOME/jdev/lib/ext directory. This will ensure that the correct connection architecture is in place. If the file is not in this directory copy it from the JDEV_HOME/bibeans/lib directory. The file olap_api_901.jar must not be in the JDEV_HOME/jdev/lib/ext directory, if it is please delete it.
Hope this helps

How to use beans in more than one page

hello members,
can somebody tell me how to make beans availabe to more than one page ,i used scope variable as "application"
in which i set the value of java bean and in that page it show all values of that bean even it modified
but when redirect to another jsp page it does not show modifided value,it shows its default value
what shld i use tell me
following thing that i use in forwarded jsp page
<jsp:useBean="same id in previous jsp page", class="same class", scope="application"/>
and then i am using boolean variable which set false default ,but i set it manually though
setfuction (assume) in original jsp page,but in redirected page it showing it value fasle
i don't know why
can somebody (Bean Bond) help me in this problem
i will very thankfull to you
plz..................

My dear friend,
your scope is wrong. Since you run a JSP page and you want it available everywhere, the only thing that all pages have common is session. So changing your bean scope to session will keep the bean variables and the rest you have on it.
Try it and let me know.
