Accessing BI graph bean from JClient
We've been trying to work with the graph bean from JClient from within JDeveloper. (The "Panel with Graph" option in File/new/Client tier/Swing/JClient for BC4j)
It looks like there is nothing in place beyond the simple graph wizard. Documentation is superficial. We can't even get axis labels to show.
The question is: where can reasonable documentation be found and if it does not exist, is it safe to use this charting product at all?
Thanks, I've also found http://otn.oracle.com/bibeans903/help/ a few minutes after posting the question. That solved the trouble for now.

For 9.0.5 the Graph integration has been greatly improved. You may want to post this message in the JDeveloper or BC4J forums so someone on their team can better assist you.

Access of JSF Beans from Servlet Filter
Is there any way how can I access session JSF beans from servlet filter?
I need to check certain value of JSF bean stored in session scope in my filter.
Thanks
ferdoFrank,
I am not sure about phase listener, this is the whole situation:
as I am not using Container Managed Security with my JSF, after I do sucessfull login into application, I need to store some information into the session scope (user etc) and in the servlet filter I need to find out if the user is connected.
I was trying to put such info into Servlet Session directly in my bean via External Context and reading the info in Filter.
This is working fine when my application is running locally (jdev oc4j) but once deployed into Application server, when user login first time, user information is somehow removed from the session, and cannot figure out why.
So I was thinking to try another approach, to find out from servlet filter if JSF bean value is set or not.
Any other suggestions? Do not want to swicth to Container Manages Security now.

JNDI Naming Problem accessing Session Bean from Message Driven Bean
Hi,
I am facing a very strange problem in JNDI look up accessing a Session Bean from a Message Driven Bean. I have a session fa�ade bean(Remote Bean) which is being called from Struts Action class getting the home reference from the ServiceLocator (I have implemented ServiceLocator pattern to obtain JNDI reference for all EJBs). When I am calling the session fa�ade EJB from the Struts Action class everything is working fine.
But when I am trying to call the same EJB from my Message Driven Bean, I am getting a JNDI exception (NameNotFoundException - No Object bound to name �java:comp/env/ejb/EJBJNDIName�). I am trying to get the remote reference from the same ServiceLocator which is successfully providing me a reference while calling from the struts action class. But the same ServiceLocator is not able to provide me a reference while calling from the Message Driven Bean. If I use the JNDI name directly like �EJBJNDIName� in the lookup it is working fine. The lookup for the name is working fine and I am able to call the Session Fa�ade bean with that reference.
I am really not sure what exactly the problem is. If I have any problem in the ServiceLocator, it should have given me the same error while calling from Struts Action class. But it is working fine with the full name �java:comp/env/ejb/EJBJNDIName� calling from the struts action class. I am not sure whether Message Driven Bean has something to do with it. Why I am not able to get a reference of the EJB with the full name? Please Help.
Thanks
AmitHi Bhagya,
Thanks for your response. I think from EJB container we can call Local EJBs with the full JNDI name. The session facade bean which is being called is a remote bean. From the session facade bean I am calling a local stateless session bean for database access. I am getting the reference of the local EJB from my session facade bean with full JNDI name "java:comp/env/ejb/EJBJNDIName". It is working fine with out any problem. My servicelocator is able to provide me the reference of the local EJB from the session facade remote bean with Full JNDI name. I am only having this problem calling from the MDB. I am really not sure whether what is causing it?
Thanks

WPC: Access Java beans from XSL
Hi,
How can we access custom Java beans from within the XSLs used to render WPC webforms? Do we have to implement a custom XSLT Helper? I am able to access standard Java classes using the <xmlns> tag but when I try to reference our custom classes the WPC editor throws a ClassNotFound exception. Any help will be appreciated.

How to use the same bean from Jsp and Servlet
I want to use the same bean instance from both the servlet and jsp.
for eg. if a create a bean using the jsp:useBean in servlet and if a modify some values, that values should be reflected while i access the same bean from the servlet. But instead of that the servlet is creating a new instance of the bean.
is it possible?
Thanks in advanceHi,
When you call jsp:useBean you inform a scope (session, request, page...)
This means the bean instance will be stored in that scope.
So, if the informed scope is session, then, in the servlet you could get the bean instance back from the session, this way:
HttpSession session = request.getSession();
Bean b = (Bean) session.getAttribute("bean_id");

Lookup of CMP Bean from client
After Deploying the CMP Bean from jdeveloper, the client is unable to lookup the Bean using the JNDI name. It gives unknown URL. All the libraries are added to the client.
Hi Zoongu,
Please look into the server.log for the actual exception message (and the stack trace).
You can call a CMP from a remote application client, but keep in mind that each and every method invocation will happen in a new transaction (there is no transaction
propagation between an app client and a server). It's a much better practice to access
a Session bean from the client (once) to perform all operations in the same transaction.

Accessing the same stateful session bean from multiple clients in a clustered environment
I am trying to access the same stateful session bean from multiple
clients. I also want this bean to have failover support so we want to
deploy it in a cluster. The following description is how we have tried
to solve this problem, but it does not seem to be working. Any
insight would be greatly appreciated!
I have set up a cluster of three servers. I deployed a stateful
session bean with in memory replication across the cluster. A client
obtains a reference to an instance of one of these beans to handle a
request. Subsequent requests will have to use the same bean and could
come from various clients. So after using the bean the first client
stores the handle to the bean (actually the replica aware stub) to be
used by other clients to be able to obtain the bean. When another
client retrieves the handle gets the replica aware stub and makes a
call to the bean the request seems to unpredictably go to any of the
three servers rather than the primary server hosting that bean. If the
call goes to the primary server everything seems to work fine the
session data is available and it gets backed up on the secondary
server. If it happens to go to the secondary server a bean that has
the correct session data services the request but gives the error
<Failed to update the secondary copy of a stateful session bean from
home:ejb20-statefulSession-TraderHome>. Then any subsequent requests
to the primary server will not reflect changes made on the secondary
and vice versa. If the request happens to go to the third server that
is not hosting an instance of that bean then the client receives an
error that the bean was not available. From my understanding I thought
the replica aware stub would know which server is the primary host for
that bean and send the request there.
Thanks in advance,
Justin
If 'allow-concurrent-call' does exactly what you need, then you don't have a problem,
do you?
Except of course if you switch ejb containers. Oh well.

Problems accessing fields in a CMP entity bean from a session bean
Hello everybody,
I'm getting the next problem: when I try to access a field in a CMP entity bean that I have instantiated from a session bean (trhoug entitybean.getNameOfField), I get the error "the entity bean does not exist in the database".
This entity bean is accessing a table in an external database (not the DB of the WAS), but I know that it's getting the correct data from the table, since I check the entitybean.size() and the entitybean.findByPrimaryKey(), and I get the right information. For some reason, the only thing that it doesn't work in the entity bean are the getter/setter methods (I created them automatically after having created the entity fields).
I access the entity bean through its local interface...
I know it's really difficult to give an answer with so few details, but... does anybody think I forgot something important to configure??
Thank very much in advance!!
Isidrogetter and setter methods for cmp-fields are abstract.
getter and setter methods for cmr-fields are abstract.

Problems accessing ejb 3.0 entity bean from project
I have written some code using ejb 3.0 and was previously accessing the entity bean without problem when both ejbs and the accessing code were in the same project. However I have moved the accessing code into a different project within the same application and now when the code tries to accessing the entity bean I get the following error:
com.colwilson.web.ingestion.IdentifiedException: java.lang.ClassCastException: __Proxy3
at com.colwilson.web.ingestion.IngestionHandler.recordArrived(IngestionHandler.java:140)

... 1 more
Now, of course I could move the code back into the same project, but as I understand it that is just the point of ejbs. I'm looking up the entity bean thus:
final Context context = InitialContext();
ingestionSessionEJB =
(IngestionSessionEJB)context.lookup("IngestionSessionEJB");
It may be true that I don't understand the way lookup works, but to be honest I can't find the docs that explain what I've got wrong.
Please help.hi
Double Click on the project which is goin to use the project which contains bean from the Application Navigator window. The project properties window will open. Choose the "Dependencies" item from left panel. click on the radio "User Project Settings" and select another project which contain ejb which you're goin to access...

Accessing a JSF element from a back bean method
Hi,
short question, can I access the JSF element from a back bean method?
So, for example, if I have the following JSF code:
<h:panelGroup id="test1" rendered="#{bean.someMethod}">...</h:panelGroup>
<h:panelGroup id="test2" rendered="#{bean.someMethod}">...</h:panelGroup>
<h:panelGroup id="test3" rendered="#{bean.someMethod}">...</h:panelGroup>
Can I found out in some way, which element (esp. which ID) calls the someMethod-method?
Kind regards
MatthiasThere are more possibilities as well. If you depend it on for example the User's rights/groups, then you can also do for example:
rendered="#{user.admin}" // getter = public boolean isAdmin()
rendered="#{user.groupName == 'admin'}" // getter = public String getGroupName()
rendered="#{user.groupId > 1}" // getter = public int getGroupId()
rendered="#{fn:contains(user.groups, 'admin')}" // getter = public String[] getGroups() or public List<String> getGroups()
etc..I think it's after all just a matter of learning about the capabilities of EL a bit more. -
Accessing Managed Beans from Code
Hi,
How can I access managed beans from my code? I am too new to JSF to know if what I am doing is right from a design perspective. But what I am trying to do is to use Actions as sort of a Web Facade that aggregates state from other beans (all of them Managed beans right now) to build up state that is necessary for displaying pages.
Thanks for you help
SuhailJust answering my own question. The answer was given in a different thread (http://forum.java.sun.com/thread.jsp?forum=427&thread=427057&message=1901909#1901909) . JSF has provided various Factories (look at the FactoryFinder API) that allow one I presume to access the internal state of a FacesContext. One of the factory is ApplicationFactory. This factory from what I can make out essentially gives you access to everything (actionlisteners, navigationhanlder,components etc) in you application. My original question was about accessing something (for some reason) named ValueBinding. I can access the managed beans declared in my faces-config.xml by invoking getValue(facesContext). I can naturally also set the value of a bean by invoking setValue(...). I just needed the getValue and it seems to work.
Ofcourse keep in mind that the underlying managed bean will not necessarily be initialized when you access it so test for nullness. As a general rule I think its best not to create the beans but access them using this facility. After all its not for nothing these are called Managed Beans.
Now if only the faces implementation would persist the changes to Navigation hanlders that one makes in the code ;-) -
Can't access a Bean from a JSP page !
Hello everybody,
I work with Oracle 8i 8.1.7, it means Oracle HTTP Server + Oracle JSP 1.1.0.0.0. But i don't use the Oracle Servlet Engine.
In this context, i try to load ` JSP page, which instantiate a Bean. But it is impossible to access to this bean !...
1) In jserv.properties file, i have mentionned the CLASSPATH to beans directory, as said in the OracleJSP documentation :
wrapper.classpath=D:\...\myBeansDirectory\
2) i have copied the .class file of my bean in the bean directory ...
So did i forget something ?
Seeking desperatly help !
Thanks.Hi,
Did you restart the HTTP listener after adding the CLASSPATH to the jserv.properties file? The change in jserv.properties (and in any other configuration files) will take effect only after the listener is restarted.
Good luck,

Access af:table values from JavaScript array (for google maps task)
Hi!
I have JSP page with af:table where latitude and longitude for google maps are stored. I am using these tutorial [https://blogs.oracle.com/middleware/entry/integrating_google_maps_with_adf] and I know how to access latitude and longitude from output text (for one point). Now i need to do something similar with loop for all table rows. How can I achieve this?
I have JavaScript code which uses Google Maps API and can display many points on one map. Also I have longitude and latitude data in af:table (bindings), each table row has one point. My task is to take data from af:table and pass it to JavaScript.
May be it is better to use managed bean as you said. Firstly I will access binding data from managed bean. Then I have to pass this data to JavaScript method? Can you suggest some example? I have "Using JavaScript in ADF Faces Rich Client Applications"My table is there :

Client Program accessing J2EE entity Bean
I have trouble find my Course J2EE bean from a client. (The client
runs on the same computer but a different VM from the bean.)
In Glassfish (Sun Application Server Nine), I set up a simple
Container-Managed Entity Bean. I tried to access it from an external
client as described in the glassfish EJB
FAQ https://glassfish.dev.java.net/javaee5/ejb/EJB-FAQ.html
Here is the client program:
package RS;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.xml.parsers.*;
import org.apache.xml.serialize.*;
import org.w3c.dom.*;
import org.xml.sax.*;
import RS.CourseHome;
import RS.CoursePK;
import javax.naming.InitialContext;
import javax.naming.Context;
import javax.naming.NamingException;
import java.rmi.RemoteException;
import javax.rmi.*;
import java.util.Properties;
import Debug.*;
public class Client {
public static void main (String arg[]) throws IOException {
try {
InitialContext jndiContext = new InitialContext ();
Debug.P("jndic ongtext" + jndiContext);
Object o = jndiContext.lookup("RS.CourseHome");
Debug.P("looked up object "+o + "|"+o.getClass().getName());
RS.CourseHome home =
(RS.CourseHome)PortableRemoteObject.narrow(o,RS.CourseHome.class);
Debug.P("got home "+home);
Course C = home.create(1);
C.setName("blah");
CoursePK PK = new CoursePK();
PK.number=1;
C = home.findByPrimaryKey(PK);
Debug.P(C.getName());
catch (java.rmi.RemoteException re) {Debug.P("Remote Exception" + re.getMessage());}
catch (javax.naming.NamingException ne){Debug.P("Naming Exception"+ne.getMessage());}
catch (javax.ejb.CreateException ce){Debug.P("Create Exception"+ce.getMessage());}
catch (javax.ejb.FinderException fe){Debug.P("Finder Exception"+fe.getMessage());}
}Here is the error message:
Exception in thread "main" java.lang.ClassCastException
at com.sun.corba.ee.impl.javax.rmi.PortableRemoteObject.narrow
(PortableRemoteObject.java:294)
at javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:137)
at RS.Client.main(Client.java:26)The debugging indicates that I got the Initial Context
and got the object but the PortableObject.narrow failed:
jndic ongtextjavax.naming.InitialContext@1d85f79
looked up object IOR: (huge number deleted)
com.sun.corba.ee.impl.corba.CORBAObjectImplEarlier, I tried the version below, but based on the suggestion by Mr. Ebbert
in the forum started "Error When running the Client Program" by sree_devi,
I checked
the following. I went to "Jndi Tree Browsing" from the Administrative Console
and I found a "RS.CourseHome" entry under "ejb" I found RS.CourseHome there
but did not see the "Course" tghat I expected to see
Thus, I tried the version above:
package RS;
--- imports deleted for conciseness
import Debug.*;
public class Client {
public static void main (String arg[]) throws IOException {
try {
InitialContext jndiContext = new InitialContext ();
Object o = jndiContext.lookup("Course");
CourseHome home =
(CourseHome)PortableRemoteObject.narrow(o,CourseHome.class);
Course C = home.create(1);
C.setName("blah");
CoursePK PK = new CoursePK();
PK.number=1;
C = home.findByPrimaryKey(PK);
Debug.P(C.getName());
catch (java.rmi.RemoteException re) {Debug.P("Remote Exception" + re.getMessage());}
catch (javax.naming.NamingException ne){Debug.P("Naming Exception"+ne.getMessage());}
catch (javax.ejb.CreateException ce){Debug.P("Create Exception"+ce.getMessage());}
catch (javax.ejb.FinderException fe){Debug.P("Finder Exception"+fe.getMessage());}
}When I run it, I get the following Naming Exception: Course not found
I confirmed at the administrative console, that I have "Course" listed
under Enterprise Applications:
As per the ejb FAQ, I set up my $CLASSPATH so it starts as follows:
/opt/j2ee/SUNWappserver/lib/appserv-rt.jar:
/opt/j2ee/SUNWappserver/lib/javaee.jar:I also verifed in my domain.xml that the orb-listener-1, the default
naming service port was at 3700.
Here is the info on the Bean that I have running for both of the tries
at my Client code.

"some other processing" comprises of printing of debug lines and publishing to the message queue using JMS. I added more debug lines so that i could see whats really happening... here is the result
myTableHome.create(...); <----------- no exception was thrown and it returned LocalMyTable object
print out "Insert successful"
print out "publishing message"
... publish message to message queue using JMS...
print out "Publish done"
... after few milliseconds...
java.sql.BatchUpdateException: Data exception -- row already exist in index PK_MYTABLE on table MYTABLE.
From the exception it seems like its doing a batch insert. So that seems to explain why the java.sql.BatchUpdateException is thrown few milliseconds after my call to myTableHome.create(...);
Is it possible to disable batch update / insert? how?
thanks in advance,
leigh
