Very Urgent !!! Exception in looking up Local EJB from Servlet in WSAD 5.1
Hi,
I have a servlet and a local EJB. The servlet and EJB are deployed on same application server but in different J2EE applications i.e. different EAR files.
When I lookup an EJB with remote interfaces from servlet everything works fine. But when I try to lookup EJB with local interfaces from
Servlet I get following Exception.
Exception Stack: -

The ejb spec only defines local ejb access within the same application. It's possible some app servers support access from a different application but it wouldn't be portable, nor would it work within the J2EE SDK or Sun Java System App Servers. To access a local ejb from a web component or ejb , define an ejb-local-ref in the client component's standard .xml file (web.xml or ejb-jar.xml) and use the ejb-link element to specify the ejb-name of the target ejb.

Challenge: call local ejb from remote ejb on weblogic 9.2
Hi ALL,
How do I call to local ejb from remote ejb object. The jar file is deployed on weblogic server 9.2, if you want get it http://geocities.yahoo.com.br/lindembe/BEAProject.jar and the source code are http://geocities.yahoo.com.br/lindembe/BEAProject.zip. It is a sample app with two ejb that works so good on JBOSS, JOnAS, but BEA Weblogic.....
The complete problem you watch http://forum.java.sun.com/thread.jspa?threadID=768718&messageID=4387570#4387570
or
http://forums.bea.com/bea/message.jspa?messageID=600043148&tstart=0Your code in SigemFacadeBean should just do:
InitialContext ctx = new InitialContext();
when you lookup the local EJB. (This will work on all app servers. There's no need to put an app-server specific intial context factory in your code.)
Also, you can remove the jndi-name setting for the local ejb from your weblogic-ejb-jar.xml. jndi-name is only applied to remote ejbs.

Problem accessing ejb from servlet
Hi,
I'm aving a problem accessing a stateful session bean from a servlet. I'm using a jndi lookup to do it because I need that a client has its own bean reference...
My code into the service method is:
InitialContext ctx;
try {
ctx = new InitialContext();
carrelloService = (CarrelloLocal)ctx.lookup("java:comp/env/ejb/Carrello");
and I have a reference to EJB into web.xml:
<ejb-local-ref>
<ejb-ref-name>ejb/Carrello</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<local-home></local-home>
<local>carrello.model.CarrelloLocal</local>
</ejb-local-ref>
If I use @EJB annotation to inject the servlet, it works fine.
Instead using jndi lookup throws a NamingException because it doesn't find java:comp/env/ejb/Carrello entry.
Any idea about the problem?Here's something simple that I have that works:
<p> </p>
SimpleBean
<p> </p>
@Stateless(name="SimpleBean")
public class SimpleBeanBean implements SimpleBeanLocal {
<p> </p>
web.xml; -- note I use a whacko ejb-ref-name just to make it obvious where I'm using it.
<p> </p>
<ejb-local-ref>
<ejb-ref-name>ejb_mapping_doodad/SimpleBean</ejb-ref-name>

Unable to access EJB from servlet
Hi,
I have in service method my servlet code.
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.ApplicationInitialContextFactory");
env.put(Context.PROVIDER_URL, "ormi://localhost/hello");
env.put(Context.SECURITY_PRINCIPAL, "admin");
env.put(Context.SECURITY_CREDENTIALS, "mypwd");
Context ctx = new InitialContext(env);
Object obj = ctx.lookup("HelloName");
HelloHome home = (HelloHome) javax.rmi.PortableRemoteObject.narrow(obj, HelloHome.class);
Hello hello = home.create();
this is how i have orion-ejb-jar.xml
<enterprise-beans>
<session-deployment name="Hello" location="HelloName" >
</session-deployment>
</enterprise-beans>
ejb-jar.xml
<session>
<ejb-name>Hello</ejb-name>
<home>examples.HelloHome</home>
<remote>examples.Hello</remote>
<local-home>examples.HelloLocalHome</local-home>
<local>examples.HelloLocal</local>
<ejb-class>examples.HelloBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Container</transaction-type>
</session>
When i access the servlet i get this error.

Is location attribute in orion-ejb-jar.xml used to specify JNDI name? Can i get the JNDI tree showing the name mappings in oc4j? How do i correct this error?
RaviRavi --
The most portable and standards oriented solution is to define an ejb-ref in the web.xml for the servlet, and then look up the name using the formal EJB UNC model.
web.xml:
<ejb-ref>
<ejb-ref-name>ejb/AppSessionFacadeHome</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<home>faqapp.ejb.AppSessionFacadeHome</home>
<remote>faqapp.ejb.AppSessionFacade</remote>
</ejb-ref>
servlet lookup
InitialContext ctx = new InitialContext();
Object homeObject = ctx.lookup("java:comp/env/ejb/AppSessionFacadeHome");
EJBHome ejbHome = (EJBHome)
portableRemoteObject.narrow (homeObject, AppSessionFacadeHome.class);

Calling ejbs from servlets without using web apps.
i am trying to instantiate and ejb from a servlet but it gives me the
following error. the configuration and code that generated this error is
attached below.
oddly enough the same chunk of code works fine in a stand alone client if
j2ee.jar;weblogic\classes and weblogicaux.jar are included in the classpath.
any help would be appreciated.

The problem before was that you were trying to load the same class from
2 different class paths. The ClassCastException is very un-intuitive in this
case.

Connecting to Remote EJB from Servlet in same application
Please help!
I was able to connect to SessionBeans and EJB from my sample java client in OCJ4 but when I try to do same thing from my web application using servlets, I get the below NullPointerException error.
The JNDI lookup works fine using java client but difficult from a servlet.
I am sure there is something I am missing.
Thanks
This is what I do in the servlet:
public void init() throws ServletException, NamingException, CreateException, RemoteException
Context jndiContext = getInitialContext();
SessionCartEJBHome home = (SessionCartEJBHome)jndiContext.lookup("SessionCartEJBBean");
sessionEJB = null;
try{
sessionEJB = (SessionCartEJB) home.create();
}catch (Exception e)
e.printStackTrace();
private static Context getInitialContext() throws NamingException
Hashtable env = new Hashtable();
// Standalone OC4J connection details
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.rmi.RMIInitialContextFactory");
env.put(Context.SECURITY_PRINCIPAL, "admin");
env.put(Context.SECURITY_CREDENTIALS, "admin");
env.put(Context.PROVIDER_URL, "ormi://Princeton/ejb1");
return new InitialContext(env);
And when I call the following procedure, it blow up at the line sessionEJB.getLineItem(new Long(1304));
sessionEJB is a class variable.
void processCatalogPage(HttpServletRequest request,
HttpServletResponse response,
ActionMapping mapping,
HttpSession session
throws ServletException, IOException , Exception, FinderException{
try {
ActionForward actFor = null;
String itemId = request.getParameter("id");
if ( itemId != null ) {
String[] itemIds = new String[1];
itemIds[0] = itemId;
sessionEJB.getLineItem(new Long(1304));
actFor = mapping.findForward("catalog");
return (mapping.findForward("success"));
} catch (Exception ex)
ex.printStackTrace();
System.err.println(ex.toString());
throw new EJBException(ex.toString());

WARNING: Unhandled Exception thrown: class javax.ejb.EJBExceptionAvi,
Thanks for your response. I am actually returning a new InitialContext in a function call in the servlet. What I have noticed though is that JDeveloper creates two ear files for the application. One for the ejbs called ejb1.ear and another for the web files webapp1.ear. These are located in the applications subdirectory in OC4J directory.
I know I have two projects in the application, model and viewController. I am just trying to follow the MVC pattern.
In short, I don't think the web and the ejbs are in same ear file. I made the web project depend on the ejbs though. There is an option to set such. I don't know how to tell JDeveloper to put them all in one ear file.
I will appreciate any suggestion.
Thanks

Exception during receive an array bytes from servlet
Hi! I have some problem with receive my array bytes. When I want to recive my array bytes at application site from servlet, I have an exception java.io.ObjectInputStream$PeekInputStream.readFully(Unknown Source) near ObjectInputStream. I don't know what it's make. All looks good. Strings send I recive without any problems. Problem is with array bytes.
URL url = new URL("http://127.0.0.1/App/servlet/Serwlet");
URLConnection connect = url.openConnection();
connect.setUseCaches(false);
connect.setDefaultUseCaches(false);
connect.setDoOutput(true);
connect.setDoInput(true);
connect.setRequestProperty("Content-Type","application/x-java-serialized-object");
ObjectOutputStream out = new sdfgObjectOutputStream(connect.getOutputStream());
out.writeObject(arrayBytes);
out.flush();
out.close();
//Here during debug is an exception
ObjectInputStream in = new ObjectInputStream(connect.getInputStream());
byte[] tmp = (byte[])in.readObject();
in.close();
System.out.println("Send array: "+arrayBytes);
System.out.println("Receive array: "+tmp);
Servlet site :
ObjectInputStream in = new ObjectInputStream(request.getInputStream());
byte[] tmp = (byte[])in.readObject();
in.close();
response.setContentType("application/octet-stream");
ObjectOutputStream out = new ObjectOutputStream(response.getOutputStream());
out.writeObject(tmp);
out.flush();
out.close();Any ideas? :]All this exception looks that :

Loading remote EJB from servlet using jakarta and openejb
I am trying to create an environment where I use
openejb as my EJB container, and JAKARTA Tomcat
as my
Servlet/JSP container. However,
i'm having a problem in lookingup my remote EJB from my
jakarta application.
That exact code works perfectly if I run it standalone. I
am using the same JRE. Jakarta has also loaded the
openejb-0.8.3.jar and openejb_client-0.8.3.jar
What I dont understand is why jakarta
would behave differently than command-line java when I
am
running in the same JRE on a single machine.
Any help would be much appreciated.Several fairly major improvements have been maid in OpenEJB specifically for the Tomcat people. For one, the whole way you integrate them has completely been rewritten. Now all you have to do is copy a openejb_loader-0.9.1.war into the Tomcat webapps directory and change an init-param in it. Pretty straight forward. OpenEJB 0.8.3 won't work with Tomcat in the same VM, however OpenEJB 0.9.0 and up have been totally revamped in all things related to classloading so that it can co-exist with Tomcats unique classloading architecture.
O'Reilly just published an article detailing the ins and outs of the integration, it's a pretty good read:

Exception looking up weblogic ejb from tomcat
i have a servlet in tomcat 4.0 doing a remote lookup on an ejb in
weblogic 6.1. the code works from a standalone client, but not in tomcat.
so i assume it is something to do with jaas. do i have to configure jaas
differently? and how?? i do not need to do anything with a standalone
client to work.
the code is
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory");
p.put(Context.PROVIDER_URL, "t3://192.168.254.3:7001");
p.put(Context.SECURITY_PRINCIPAL, "user");
p.put(Context.SECURITY_CREDENTIALS, "password");
InitialContext ctx = new InitialContext(p);
the exception is

Security exception while trying to access EJB from stand alone client
Hi!, I am trying a sample EJB application to R&D some security related issues. I want to access EJB through a web application as well as a stand-alone client. I have set approriate <method-permission> in EJB deployment descriptor. I am using users.properties/roles.properties file for authentication mechanism. I am using JBoss 3.2.
- On the web application side I am using BASIC authentication and the servlet is able to access the EJB OK, as long as I am using a login/password that has access to the EJB.
- Now I am trying to access the EJB using a stand alone Java class. These are the things I have tried till now:
=>Created a InitialContext with appropriate principal, credentials and tried getting a reference to EJB home interface. That resulted in security exception.
=>Logged into a LoginContext by using appropriate JBossSX classes and then tried getting a EJB home interface. Again security exception.
Now I am not sure what to do. I read at some places about client side container but not sure what that is. Does anyone has any ideas to try? Is there any other way I can make a swing application and a web application authenticate to EJB container?
Also can anyone point me to any documentation that gives some idea about how the security credentials gets propagated from web application/standalone client to EJB container?It would be better if you can post your code...and DD that way we can help you better

Help neede very very urgently ... to clear the report from Cache.....
Hello all,,,
In my project iam using crystsal report for eclipse to generate reports.
Iam using a .jsp page to call my report.(which i got it from the examples of CRE).
The name of my jsp page is poi.jsp
The name of my Crystal report is CrystalReport2.rpt
My problem is this....
when i run the report first time i can see my poi.jsp page and user can submit
the parameter and based on the users parameter the report is generated..(ITs working absoultely fine)
but when the user runs the report again, its not showing the parameter page (i.e user cannot see poi.jsp)
rather its showing the old generated report.
When i tried using session.invalidate and session.removeAttribute it was showing me the poi.jsp page
but the problem is when the user clicks on the print icon or any icon on the report its just
showing the poi.jsp page...
When the user closes the report or when the clicks on the button to generate the report it should
show the parameter page (poi.jsp).how can i solve this problem???
the code what iam using is as follows..( got it from the examples of CRE - database login )
Object reportSource = session.getAttribute("reportSource");
if (reportSource == null)
String report = "CrystalReport2.rpt";
ReportClientDocument reportClientDoc = new ReportClientDocument();
reportClientDoc.open(report, 0);
reportSource = reportClientDoc.getReportSource();
session.setAttribute("reportSource", reportSource);
ConnectionInfos connInfos = new ConnectionInfos();
IConnectionInfo connInfo1 = new ConnectionInfo();
connInfo1.setUserName("USER");
connInfo1.setPassword("USER");
connInfos.add(connInfo1);
CrystalReportViewer viewer = new CrystalReportViewer();
viewer.setReportSource(reportSource);
viewer.setEnableLogonPrompt(false);
viewer.setDatabaseLogonInfos(connInfos);
if (session.getAttribute("refreshed") == null)
viewer.refresh();
session.setAttribute("refreshed", "true");
viewer.setOwnPage(true);
viewer.processHttpRequest(request, response, getServletConfig().getServletContext(), null);
//session.removeAttribute("refreshed");
//session.invalidate();
thanks in advance
regards
jackAs far as parameter refresh is concerned add in your code
viewer.setHasRefreshButton(true)
refresh button is appeared on crystal report toolbar and you can use this button instead of explorer refrsh button and every time you can add new parameters values.
Also, if you want to update reportsource in session object. means if user wants to view more than one different reports and want to invalidate reportsource form session.
add in jsp.
session.removeAttribute("reportSource");
Happy programming

Reference EJB from servlet's action/helper classes
Hello
How to make a reference to stateless session bean from one of the helper classes of a servlet WITHOUT using any of these:
* dependency injection (like @EJB) - I think this is not supported in this kind of class, EJB references can be injected only to servlets themselves or some other things (but not objects of classes "accompanying" a servlet)
* home or local home interfaces (I would like to avoid writing them)
* using mappedName (either in @Stateless or in ejb-jar) - since meaning of this is application-server dependent and thus not portable.
By a "class accompanying a servlet" / "helper class" I mean utility or action classes, like MyActionClass, which would be instantiated and then used by a aforementioned servlet.
Thanks.The EJB dependency must be looked up via the java:comp/env namespace since as you point out
Java EE 5 environment annotations are not supported on POJOs. However, the dependency itself
can either be defined using @EJB on some other managed class in the .war or within the
web.xml. We have an entry in our EJB FAQ that has the details :
https://glassfish.dev.java.net/javaee5/ejb/EJB_FAQ.html#POJOLocalEJB
Also, whenever the client component resides in the same application as the target EJB (which is
required for Local access but not for Remote access) there is no need to use mappedName to
resolve the EJB dependency. It is either automatically resolved if the business interface type of
the EJB dependency is only exposed by a single EJB in the application, OR the beanName()
/ ejb-link attributes can be used to unambiguously identify the target EJB using ejb-name.
You can find more about this in the FAQ as well. -
