How call session bean from Client side
Hi
calling session bean from client side it gives Lookup erroe, it gives JNDI error
how we know session bean is working. in Admin tree bean statis is reb Flaf, and ID is "Down" how we activate it..
null
If you can make a connection using sess_sh, then you know that you have configured your database and listener properly. If it is not working, read the manuals that you can download from technet. They are pretty good, and if you follow the directions, you should see success.
Good Luck!

Problem when calling session bean from main.
Hi everyone
I get the following error when calling a session bean from main(String args[]).
Sep 3, 2008 9:11:13 AM com.sun.enterprise.appclient.MainWithModuleSupport <init>
WARNING: ACC003: Application threw an exception.
java.lang.NullPointerException
at databasetest.Main.main(Main.java:26)
Here is my code beneath.
I'm using netbeans and glassfish application server.
Everything is in the same project, called DatabaseTest, I also have deployed the application before running the client.
I'm running the client as follows, right click on the DatabaseTest-app-client and select run.
The client:
package databasetest;
import com.test.UsersFacadeRemote;
import javax.ejb.EJB;
import com.test.Users;
public class Main {
@EJB
private static UsersFacadeRemote usersFacade;
public static void main(String[] args) {
Users users = new Users(12, 34);
usersFacade.create(users);
}The remote facade I'm calling:
package com.test;
import java.util.List;
import javax.ejb.Remote;
@Remote
public interface UsersFacadeRemote {
void create(Users users);
void edit(Users users);
void remove(Users users);
Users find(Object id);
List<Users> findAll();
}The stateless bean:
package com.test;
import java.util.List;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
@Stateless
public class UsersFacade implements UsersFacadeRemote {
@PersistenceContext
private EntityManager em;
public void create(Users users) {
em.persist(users);
public void edit(Users users) {
em.merge(users);
public void remove(Users users) {
em.remove(em.merge(users));
public Users find(Object id) {
return em.find(com.test.Users.class, id);
public List<Users> findAll() {
return em.createQuery("select object(o) from Users as o").getResultList();
}looks like you're banging your head against the same brick wall as [I have done|http://forums.sun.com/thread.jspa?forumID=13&threadID=5317110] and [others have in the past|http://forums.sun.com/thread.jspa?forumID=136&threadID=5259913] if that's any consolation.
Funny thing is, mine did actually work in the debugger but not when running!
Strange thing that.
I did initially interest someone from the developers but they couldn't really help, ended up saying : try instantiating your beans the EJB 2.1 way and see where that gets you. Yes that works but they promised us "hey no more dopey xml deployment descriptors just some cool annotations" didn't they?
I've got the feeling were' missing something really obvious!

I'm trying to build a online image resize tool.
problem i face are:
1. I build a button that allow user to browse the file. Once
file is selected, it doesnt show full path.
2. lets say if it shows fullpath, but i try to load it into a
movieclip, and it doesnt work because the swf file is located at
the server and not the client's place.
3. as far as i know, flash can only load images which is
located in the same server or internet.
4. if i use php, asp, cgi.. it can only allow me to 1st
upload the image then resize later, but this is not wat i want.
5. I need to 1st resize then upload later, because if i have
100 and more photos taken from digicam, it's going to be very slow
and heavy.
What i have tested:
1. upload "image3.jpg" into the same directory as the
"viewer.swf", and it works.
2. do not upload the swf to the server, but run locally from
the user's computer and open "image3.jpg" and it works.
3. upload the swf to the server and open "image3.jpg" from
the user's computer and IT DOESN"T WORK!
please help me out.
Thanks~!use this php code.
for flash php image prosses.
flash file

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.

Each app server provides their own jndi factory class. For ex for weblogic it is weblogic.jndi.WLInitialContextFactory. SInce you are using sun app server, check if there are any examples to find out or the docs.
private static String url="http://localhost:4848
Since the client is in a different machine the localhost is not going to work here. provide the url or the machine name of the system in which ur sunapp server is running. In addition u will need to have the stubs of the remote interfaces in ur client machine. -
How can i load file into database from client-side to server-side
i want to upload file from client-side to server-side, i use the following code to load blob into database.
if the file is in the server-side, it can work, but if it in the client-side, it said that the system cannot find the file. i think it only will search the file is in the server-side or not, it will not search the client-side.
how can i solve it without upload the file to the server first, then load it into database??
try
ResultSet rset = null;
PreparedStatement pstmt =
conn.prepareStatement ("insert into docs values (? , EMPTY_BLOB())");
pstmt.setInt (1, docId);
pstmt.execute ();
// Open the destination blob:
pstmt.setInt (1, docId);
rset = pstmt.executeQuery (
"SELECT content FROM docs WHERE id = ? FOR UPDATE");
BLOB dest_lob = null;
if (rset.next()) {
dest_lob = ((OracleResultSet)rset).getBLOB (1);
// Declare a file handler for the input file
File binaryFile = new File (fileName);
FileInputStream istream = new FileInputStream (binaryFile);
// Create an OutputStram object to write the BLOB as a stream
OutputStream ostream = dest_lob.getBinaryOutputStream();
// Create a tempory buffer
byte[] buffer = new byte[1024];
int length = 0;
// Use the read() method to read the file to the byte
// array buffer, then use the write() method to write it to
// the BLOB.
while ((length = istream.read(buffer)) != -1)
ostream.write(buffer, 0, length);
pstmt.close();
// Close all streams and file handles:
istream.close();
ostream.flush();
ostream.close();
//dest_lob.close();
// Commit the transaction:
conn.commit();
conn.close();
} catch (SQLException e) {Hi,
Without some more details of the configuration, its difficult to know
what's happening here. For example, what do you mean by client side
and server side, and where are you running the upload Java application?
If you always run the application on the database server system, but can't
open the file on a different machine, then it sounds like a file protection
problem that isn't really connected with the database at all. That is to
say, if the new FileInputStream (binaryFile) statement fails, then its not
really a database problem, but a file protection issue. On the other hand,
I can't explain what's happening if you run the program on the same machine
as the document file (client machine), but you can't write the data to the
server, assuming the JDBC connection string is set correctly to connect to
the appropriate database server.
If you can provide some more information, we'll try to help.

How to use KeyChain API from client-side HTML scripting in Safari on iPad?
I have a requirement where I need to add client-side scripting in an HTML page to be supported by Safari on iPad that creates a private / public key pair and that creates a CSR (Certificate Signing Request) in PKCS#10 or SPKAC format that can be sent to a certification authority server using form HTTP/POST that will then return the generated certificate.
I initially thought that I could simply use the HTML 5 tag <keygen> which can do exactly what I need, but unfortunately this tag is not at all supported on mobile Apple devices like iPad or iPhone, so I have to look for another solution.
I have noticed that the KeyChain tool should be available on iPad using the documented API, but I have no idea based on the documentation whether the API can be called from client-side HTML scripting on iPad.
Question : is it technically possible using the functionalities and API's exposed on an iPad to implement what I just described in HTML client-side scripting? If so, do you have some links with useful information that can help me on my way?I have a requirement where I need to add client-side scripting in an HTML page to be supported by Safari on iPad that creates a private / public key pair and that creates a CSR (Certificate Signing Request) in PKCS#10 or SPKAC format that can be sent to a certification authority server using form HTTP/POST that will then return the generated certificate.

How can I set the value to a session bean from backing bean
Hi Experts,
How can I set the value to a session bean from backing bean where I have created getter and setter
methods for that variable.
Basically I am using ADFUtils class where I am able to get the value from session bean
using following expression
String claimType =
(String)ADFUtil.invokeEL("#{ClaimValueObj.getClaimType}");
Thanks

How to call session bean's method in JSP
Hi All,
I am working on a JSF web application by using sun studio creator.
The first page have a button, the onClick javascript is as following, which bring up a alert box showing user login name.
In JSP file, how can I call session bean's setUserName(String name) function (which I would like to store this UserName). So the following pages can use this information.
If I can not do it this way, is there any other way to do it?
Thanks in advance.
var net = new ActiveXObject("wscript.network");
alert(net.UserName);
In managed-beans.xml
<managed-bean>
<managed-bean-name>BasicInfo</managed-bean-name>
<managed-bean-class>treepractice.BasicInfo</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>You can find more information/details/examples at their own website.
On the other hand, do you realize that that ActiveX stuff is IE proprietary? And that it is a browser configuration whether to allow them or not? And that this configuration is in IE7 defaulted to an (annoying) warning box before execution which is just bad for the user experience?
With other words, forget that ActiveX garbage. Alternatives are Applets (not recommended) or Java Web Start (recommended). -
Trying to call stateless session bean from MDB
Folks,
Am working on RAD and WAS 8.
I have an MDB. And a stateless session bean (AOBean under EJB project).
While the listener listens to the messages from queue, it also tries to persist to db. I want to achieve this via a method of AOBean (through instantiating session bean or by injection).
I have been sucessful by invoking a method from AOBean class - that method just returns a string (without any objects being passed)
Problem:
I am getting IllegalStateException when I try to invoke a method of AOBean class, that has an object as a parameter
For eg:
MDB
@EJB(name="ejb/TransactionMgrAOBean", mappedName="ejb/TransactionMgrAOBean")
ITransactionMgrAO tranAO;
public void onMessage(Message message) {
TextMessage textMessage = (TextMessage) message;
boolean status = false;
try {
TransactionVO tranVO = getTransactionVO();//Here building the object to be passed to session bean
String status1 = tranAO.getVersion(tranVO);
}catch(Exception e){
AOBean
@Stateless
@Remote({ ITransactionMgrAO.class })
@WebService
public class TransactionMgrAOBean {
public String getVersion(TransactionVO tranVO) throws Exception{
try{
//business logic
} catch(Exception e){
throw e;
return true;
TransactionVO implements Serializable has also inner static classes that are not Serializable.
EXCEPTION: At runtime we are getting exception saying that the inner classes are not serialized.
REASON why we are invoking session bean from MDB? We found that if we invoke any service from AOBean the transaction management was successful. We are using sessionContext.setRollBackonly when an exception occurs. Tranasactions are not rolled back when any db exception occurs if we invoke business logic methods from Model layer of another NON-EJB package.
Hope I have provided enough information!My concret problem is that I want to call an ejb session contained in an ejb project from a session bean in a different web project. When I include the code in my web session bean I get the error adjunted:
- Code:
@EJB
private UserRemote userSessionBean;
- Error:
Exception Details: javax.naming.NameNotFoundException
pac.UserRemote#pac.UserRemote not found
Possible Source of Error:
Class Name: com.sun.enterprise.naming.TransientContext
File Name: TransientContext.java
Method Name: doLookup
Line Number: 216
Any suggestion?
