Creating a bean within another bean and JNDI

Hello,
I am trying to have one bean (a session bean) create another bean (entity
bean). I keep getting a naming exception. Both beans are deployed in the
same JAR file. Also, I can directly create the entity bean (from a client
test app).
Here is the code I have in the session bean:
try
Context initial = new InitialContext();
Object objref = initial.lookup("java:comp/env/ejb/User");
UserHome userHome =
UserHome)PortableRemoteObject.narrow( objref, UserHome.class );
user = userHome.create( username, password );
catch( NamingException e )
e.printStackTrace();
The result is a naming exception, which is shown below. Why does the naming
exception say "comp.env.ejb.User"?
***** Naming Exception *****
javax.naming.NameNotFoundException: 'comp.env.ejb/User'; remaining name
'ejb/Use

thanks, but look at the new code i modified still given error on not resolving the class LoginBean in the class LoginDataBean. here is the new code.
package webclass;

public class LoginDataBean
     private Connection cn;

Injecting a bean in another bean in EJB3?

Hello all,
I am trying to inject a bean in another bean, then making a JUnit test for the parent bean. The problem is that it is displaying a nullpointerexception.
Is the way of injection of a bean in another bean different from injecting a bean in JSF backing bean or any other client?
I am using glassfish and EJB 3.
Here is the code.
JUnit Test
@Test
    public void testReturnRequestURL() {
        List<String[]> listParameters = new ArrayList<String[]>();
        /* Assigning values for variables */
        ABean instance = new ABean();
        String result = instance.returnString(listParameters);
        System.out.println(result);
Parent EJB
@Stateless
public class AccountsCheckingBean implements AccountsCheckingBeanInterface {
    @EJB
    private BBean bBean;
    public String returnString(List<String[]> listParameters) {
        String strNew = new String();
        strNew = bBean.appendXML("fileName.xml", listParameters); // *returns null here*
        return strNew;
}What's going wrong here?

Thanks for your reply. I am using the integrated WLS for this test.
However, I think it might not be a previous deployment issue. I removed the dependency of ModelEJBOne on ModelEJBTwo and the application loads successfully.
No new Session Bean was created or modified when the application failed to load. I only added a dependency that ties project ModelEJBOne to project ModelEJBTwo when it failed to load.

How to get the value of a session bean through a scriptlet

Hi,
I have defined a session bean in faces-config file and now I want to acces this bean object through a scriptlet. How should I go about doing that ?
eg in faces-config file I have something like this
<managed-bean>
<managed-bean-name>pc_DepTest</managed-bean-name>
<managed-bean-class>pagecode.WEBINF.Pages.DepTest</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
Now in another pager called xyz.jsp
I want to access the pc_DepTest object through a scriptlet... How should I do that ?
Thanks

I avoid scriplets, but you could write:
pagecode.WEBINF.Pages.DepTest test = (pagecode.WEBINF.Pages.DepTest) FacesKit.getBean("pc_DepTest");
//you use WEBINF in package names? gack!
...Where in FacesKit you've defined:
public static Object getBean(String expr){
    FacesContext context = FacesContext.getCurrentInstance();
    Application app = context.getApplication();
    ValueBinding binding = app.createValueBinding("#{" + expr + "}");
    return binding.getValue(context);
}

How to use PropertyChangeSupport for a bean from another bean

Hi all,
I have a bean A that doesnot implements the PropertyChangeListener or have a PropertyChangeSupport as one of its member and I cant change its design. I want to fire an PropertyChangeEvent when a property is changed. I added A to PropertyChangeSupport of another bean B. The problem is that even if the Property of Bean A is changed it doesnot fire a event. Can anybody let me know how to do it?
Thanks,
Amit

You need to wrap bean A inside another bean (B) that
implements the accessor and mutator methods of Bean A
and adds property change support in those methods
where appropriate. You hide the actual instance of
bean A inside an instance of bean B so no instances of
bean A are visible to the application.This is OK, unless you don't want to change all places where A is referenced. You could subclass B from A, as long as the accessor and mutator methods are not final. Of course, instantation still has to know about B and you will have to cast to B, or use reflection, to add and remove the listeners.

Set value of variable in one bean from another bean

Using JDeveloper 11.1.1.4, I thought this would be simple to do, but I haven't been able to figure out the correct syntax and am just learning java. In my view controller I have one bean set as pageflow scope, and another bean set as a request scope. How do I set the value of a variable in the first bean from the second bean? The first bean has setters and getters, but when I try to reference them in the second bean, it says it isn't allowed. The first bean looks like:
public class ViewAmtsParameters {
    String asOfDateParam = null;
    public void setAsOfDateParam(String asOfDateParam) {
        this.asOfDateParam = asOfDateParam;
    public String getAsOfDateParam() {
        return asOfDateParam;
}Thanks in advance,
Troy

How to get iterator values from a managed bean ?

Due to a bug in selectOneChoice i'm not able to get the label list i want to display directly from an iterator when the value binding is a managed bean.
To solve the problem i would like to create a managed bean that contains that list and use it as the selectItems to display.
I would like that the values in that managed bean loaded from the a data control iterator.
My question is :
1) is it possible to access the iterator values from a managed bean, i mean without any reference to a page definition
2) how to do ? is it documented somewhere ? any example ?
Thank you

I got it also with this code:

How to get current db value in backing bean

Hi,
I'm using jdeveloper 11.1.2.3.0
I would like to know how could I access the old value of an attribute in backing bean.
I know I can get it in the EntityImpl level with getPostedAttribute function,
but as I see I don't have permission to access this function in the ViewImpl.
I get this error:
Error(151,33): getPostedAttribute(int) has protected access in oracle.jbo.server.EntityImpl.
Could you help?
What is the correct way to get the current value on db in backing bean?
Thanks a lot!

You can add a transient attribute to the Entity object to hold the old value of the desired attribute, then you can add this attribute to the view object.

How to get a int value from another class method?

Hi,
how can I get a value of another class method variable value.
example,
class elist
        int a;
     ArrayList<Event> eventArray;
     void addEvent(Event e);
     Event getEvent(int index);
     void removeEvent(int index);
     void orderEventByTime();
interface Event
     void Command();
class servo implements Event
     String ip;
     int time = 10;
     void Command();
class servo_2 implements Event
     String ip;
     int time = 20;
     void Command();
[\code]
I want to get the time value in elist variable a;
and want to compare each class time?.

Hi,
1) this foum provides means to format/tag code, no need to manually add -tags
2) by default, classname start with a capital letter, method names with a lower case letter
3) where do you want to get the time value to Elist.a? During addEvent()?
4) what do you want to do with the time value of each event? Sum all values up to make a an overall sum?
5) where do you want to compare the time value(s)?
To put it in one sentence: please be more specific with your description and answer.
Bye.

How to get user defined class in java client of a bpel prcoess?

I have written a simple bpel process which returns a bean class namely employee which has three String fields(name,id and email). From java client when I am invoking the prcoess the prcoess instance is starting and completing properly. From Bpel console when I check the audit of the instance, it shows everything as expected. But in client class instead of three strings I am getting only first string i.e email in response. I checked the mapping and all WSDL files but could not find a proper reason. I am attaching the wsdls of bpel prcoess and the client code:

Hi Abdul,
From the document, we know that CONSTRAINED flag is used to reduce the risk of injection attacks via the specified string. If a string is provided that is not directly resolvable to qualified
or unqualified member names, the following error appears: "The restrictions imposed by the CONSTRAINED flag in the STRTOSET function were violated."
So you need to make sure the members are passed properly to the STRTOSET function. For more details, please see the following links:

Hope this helps.

How to get cookie value setup by another servlet?

Hi, Steven,
I was trying to get a cookie value setup by another servlet. I thought it should appear under /request/cookies/ node. But it didn't.
What I did was use the following code in a servlet to add a cookie in the server:
Cookie c = new Cookie("ID", "123");
res.addCookie(c);
Is the node ID suppose to appear under /request/cookies/ node when I reload my xsql file?
I can do this use session value. However, it is not easy to setup max age for session value. Would you please give me any suggestion about how to handle this problem? Thanks in advance.

Are you talking about server-side java code (servlets/jsp) or client side (applet)? Given we are in the JSP forum I'll assume we're talking server side.
If so, you are making a common but fundamental mistake. JavaScript executes on the client, not on the server. If you want client data on the server it has to get there somehow. The simplest way to do this in JSP land is via HTTP. So... have your JavaScript code call a JSP (or servlet) and pass the value you want as a URL parameter. Of course this will also change the browser location, so if you don't want this to happen use a frame or iframe to capture your HTTP request.
For example:
Javascript....
function someFunction() {
return 1;
var value = someFunction();
location.href="somejsp.jsp?value=" + value;

How to get the IP address from baking bean?

Hi, Im new to the JSF technology and want to find out how can i get client related info in the baking bean, like IP Address, USER_AGENT and that kind of thinks, any guide you could give me would be great, thanks in advance.

You can use javax.faces.context.ExternalContext object to get various raw request information
including HTTP request headers. Also, you could call request.getRemoteAddr() method indirectly
from the object.

PLZ Help: how to get value of a request scoped Bean/Attribute in JSF ?!!!

hi,
I noticed this part of code to retrieve session scoped beans/vars in an ActionListener or other jsf classes, but it does not work for request scoped beans/vars :( what's the problem then ? what shall i do ?
Type var = (Type)Util.getValueBinding("myBeanInRequest")).getValue(context);
I have also set that getPhaseId() returns UPDATE_MODEL_VALUES or APPLY_REQUEST_VALUES.
Any comment or idea ?

I have declared my Bean in my JSP page not in the
faces-config.xml. Does this make any problem ? Also I
have tried the way you told me as well, but still the
returned attribute is null.
P.S. My bean is declared in my JSP page this way:
<jsp:useBean id="newSurveyVar" class="SurveyModel"
scope="request" />
This declaration causes the SurveyModel instance to be created in request scope when the page is rendered, but that doesn't help you when the form is submitted -- that is going to happen on the next request (so the request attribute created here goes away). Basically, <jsp:useBean> is not typically going to be useful for request scope attributes (it's ok for session or application scope, though).
and further I have this jsf code:
<h:command_button label="Create" commandName="create"
action="create" >
<f:action_listener
r type="CreateNewSurveyActionListener"/>
</h:command_button>
and this is my
CreateNewSurveyActionListener.processAction(ActionEvent
e) {
if (actionCommand.equals("create_the_survey")) {
FacesContext context =
t = FacesContext.getCurrentInstance();
SurveyModel survey =
y =
(SurveyModel)(Util.getValueBinding("newSurveyVar")).get
alue(context);
if (survey==null) // returns true :(((
And since I've declared my beans here there is nothing
special declared in my faces-config.xml
For me again it is really strange why it is not
working !!!
Any idea ? Because the event listener is fired in a separate request, so the one you created in the page is gone.
This is why the managed bean creation facility was created. If your component contains a valueRef that points at the bean name (or you evaluate a ValueBinding as illustrated earlier in the responses to your question), then the bean will get instantiated during the processing of the form submit.

How to get the defined printers in anothers computer withen my LAN

happy new year for ALL
I want to put a JAR file in the server. this JAR file enable users to print images from this server.
the problem: I want to print the image in user's printer not in the server printer.
so I want to get the printers defined in the user computer and print th image on his/her printer.
waiting your reply

There is a Java Print API. It has nothing to do with networking.
The images must be moved from the server to the client. You didn't make it clear in what form the images exist. However that is a standard web application idiom. And it should probably be addressed as that rather than as a networking problem (since as a web application there are other parts that will probably help.)
