Can't invoke method on a co-deployed bean

I've got two EJB's deployed in the same jar file. JtdaRequest, a stateful session bean, calls DeersRequest, a stateless session bean. JtdaRequest finds and instantiates a DeersRequest, but when invoking a business method, it causes the following:
calling jtdaRequest.request() error in authenticate java.rmi.ServerException: RemoteException occurred in server thread; nested exception is: java.rmi.RemoteException: nested exception is: java.rmi.ServerException: RemoteException occurred in server thread; nested exception is: java.rmi.RemoteException: nested exception is: javax.ejb.EJBException: nested exception is: javax.ejb.CreateException: Could not create stateless EJB: java.lang.reflect.InvocationTargetException; nested exception is: javax.ejb.EJBException: nested exception is: javax.ejb.CreateException: Could not create stateless EJB: java.lang.reflect.InvocationTargetException; nested exception is: java.rmi.ServerException: RemoteException occurred in server thread; nested exception is: java.rmi.RemoteException: nested exception is: javax.ejb.EJBException: nested exception is: javax.ejb.CreateException: Could not create stateless EJB: java.lang.reflect.InvocationTargetException; nested exception is: javax.ejb.EJBException: nested exception is: javax.ejb.CreateException: Could not create stateless EJB: java.lang.reflect.InvocationTargetException at com.sun.corba.ee.internal.iiop.ShutdownUtilDelegate.mapSystemException(ShutdownUtilDelegate.java:68) at javax.rmi.CORBA.Util.mapSystemException(Util.java:65) at mil.osd.dmdc.deers.web.jtda.ejb.jtdaRequest._JtdaRequest_Stub.request(Unknown Source) at mil.osd.dmdc.deers.web.jtda.ejb.jtdaRequest._JtdaRequest_Stub.request(Unknown Source) at EJBInvoke.doGet(EJBInvoke.java:101)This worked on SJSAS version 8, but not 7. Have put the generated JtdaEjbClient.jar file in the classpath of the server, restarted, to no avail.

Invoking methods in C++ from Java

I'm invoking the Java Virtual Machine from my C++ program like is described here: http://java.sun.com/docs/books/tutorial/native1.1/invoking/invo.html
So, I run my C++ program (let's call it C), C invokes the JVM and starts a Java program (let's call it J). C can now invoke methods in J. Now I want J to invoke a method in C. Is this possible?

Yes it is.
However your C code that you want to invoke from java must be defined as "native" - that is, it is defined as the implementation for java methods that are declared native.
The possibly most confusing part is where to put the C code and how to make the java-C linkage.
o You can put the C code in a DLL, and use a "loadLibrary" call to make it available.
o Alternatively, and perhaps more likely, your original C/C++program can make "registerNative" calls to the JVM to identify to it the native implementations.

Can we invoke a method using BCEL(byte code engineering library)

Hi i am new in Java bcel,So can anyone guide me in this problem.
I am searching for some techniques in BCEL to invoke a method of some class just like we use to invoke methods using Java Reflection.I have also tried a Java Assembler named "Jasmin" that used to interact with Operand Stack,Local variable array & Constant Pool etc so i guess this is the same containers with which our BCEL also interact with so then i am wondering why not then there exists a way through which we can invoke a method using BCEL IF this will happen in any case then kindly point it out some direction of help.
thanks in advance

I think i have clearly mentioned that "Tell me any way in doing this invocation in BCEL not in Reflection."
Why i not want to use reflection because it have "invocation overhead"Wrong.
If I dynamically load a class and reference it via a interface there is absolutely no difference in that and if I referenced the class statically and used it via an interface. The load and use process is exactly the same.
And the first uses "reflection".
If you use a proxy interface via something like java.lang.reflect.Method
then of course there is some overhead because there is in fact more classes involved. Just as if you had any other layer in any other code.
And even so unless you have actually profiled the application and found an actual bottleneck (and not just a measured impact) then even looking at it is a waste of time.
If it was me I would be far more concerned that inserting byte codes was correct for all cases.

Why can't use all the function when deployed Duke Bank successfully

i am use the DukesBankApp.ear in j2eetutorial14 to deployed .When i change the "public Object ejbCreate() throws CreateException" to "public String ejbCreate() throws CreateException",deployed Duke Bank successfully
But,I open the client,i can not use all the function. for example,when i creat new customer or account .Applecation message watch will say "remote exception"
why?or send the true DukesBankApp.ear to me .My mailbox is "[email protected]"

How can one invoke a WebLogic EJB from a BPEL Server hosted on OC4J?

How can one invoke a WebLogic EJB from a BPEL Server hosted on OC4J?
Reason I ask is I keep getting this error:
javax.naming.NoInitialContextException: Cannot instantiate cla
ss: weblogic.jndi.WLInitialContextFactory [Root exception is java.lang.ClassNotF
oundException: weblogic.jndi.WLInitialContextFactory]
Note: I am using <bpelx:exec> as a way to execute some java program.
Essentially my java client (essentially an EJB client hosted on Oc4J) needs access to wlclient.jar since it needs access to weblogic.jndi.WLInitialContextFactory. I have a EJB client running on BPEL server hosted on Oc4J that needs to access some EJBs hosted on weblogic.
Where do I place this wlclient.jar so that BPEL PM can start peacefully and at runtime discover the InitialContextFactory classes?
Placing it in the j2ee/home/applib doesn't solve the problem. The server fails to start up if I do this
I tried placing it in BPEL-INF\lib directory ...
I still get the same exception...see below for exception dump
I verified the BPEL suitcase, and it in fact does contain the jar file wlclient.jar
integration\orabpel\domains\default\deploy contains the bpel_BPELProcess2_1.0.jar file and snapshot of that is as follows:
<PRE>
│ bpel.xml
│ BPELProcess2.bpel
│ BPELProcess2.jpr
│ BPELProcess2.wsdl
│ bpel_BPELProcess2_1.0.jar
│ build.xml
│ buildxml.copy
│ graphics.xml
│
├───BPEL-INF
│ └───lib
│ myEJB.jar
│ wlclient.jar
│
├───META-INF
│ MANIFEST.MF
│
└───output
bpel_BPELProcess2_1.0.jar
</PRE>
I tried using the BPEL-INF\jar directory...Is this something the obant automatically detects? or do I have to modify the build.xml? I created this directory and let Jdev deploy to local BPEL server->default domain handle it
#####################3
I even tried copying the wlclient.jar to
integration\orabpel\system\classes but this doesn't help since the BPEL PM fails to start if I explode this jar into this directory.
In short,where do I place the wlclient.jar so that this exception can be contained.
I edited the build.xml to point to the jar, that too didn't work, unless I made some mistake in the file
<bpelc classpath="${basedir}/BPEL-INF/classes;${home}/system/classes;${home}/lib/j2ee_1.3.01.jar;${basedir}/BPEL-INF/jar/wlclient.jar" input="${basedir}/bpel.xml" rev="${rev}" deploy="${deploy}" />

with the bpelx all I have is two lines of code that creates a java object and calls a method on it.
The method does this:
    private String initialContextFactory = "weblogic.jndi.WLInitialContextFactory";
    private String providerUrl = "t3://localhost:7001";
    private String urlPkgPrefixes = "";
    private String mapEjbJndiName = "ejb/mycompany/Redlands";
    public String getDefaultMapName() {
      try {
          Hashtable env = new Hashtable();
          env.put(Context.INITIAL_CONTEXT_FACTORY, getInitialContextFactory());
          env.put(Context.PROVIDER_URL, getProviderUrl());
          if (getUrlPkgPrefixes() != null && !getUrlPkgPrefixes().equals(""))
              env.put(Context.URL_PKG_PREFIXES, getUrlPkgPrefixes());
          System.out.println("    " + getInitialContextFactory());
          System.out.println("    " + getProviderUrl());
          System.out.println("    " + getUrlPkgPrefixes());
          System.out.println("    " + getEjbName());
          // Get a naming context
          context = new InitialContext(env);
           Object ms = context.lookup(getEjbName());
          MyEJBHome home = (MyEJBHome ) PortableRemoteObject.narrow(ms, MyEJBHome.class);
          myEjb = home.create();
          return myEjb.getDefaultName();
      } catch (RemoteException re){
          System.out.println(re.getCause().getMessage());
      catch (Exception ex) {
          ex.printStackTrace();
      return null; //if unable to resolve the context factory etc...
    }

I did exactly as you suggested. I edited the application.xml and added this
<library path="C:\ArcGIS\test\bea\wlclient.jar"/>
I didn't add weblogic because the needed classes were all in wlclient.jar
I also edited the BASE_OB_CLASSPATH to include this jar.
Here is the result when I just start BPEL PM Server. Somehow BPEL PM doesn't like to have wlclient.jar in its classpath during startup.

SEVERE: Caught an exception while invoking method 'setFlag' on object 'Lock

While try to run load test data , I got the exception as follows..
SEVERE: Caught an exception while invoking method 'setFlag' on object 'LockManager'. Releasing locks.
java.lang.reflect.InvocationTargetException
Finally I got a hint ,
"If the running Deployment Template script breaks halfway through its execution due to an unhandled
exception, or is manually interrupted by a user pressing Ctrl-C while it is running, the lock remains
set within the EAC"
The resolution is ,
On Windows: .\runcommand.bat LockManager releaseLock
update_lock
On UNIX: ./runcommand.sh LockManager releaseLock up¬
date_lock

After spending some time on this, I looked at the source code for com.evermind.server.ThreadState
This is the code that throws the exception:
if(applicationThread != null && applicationThread.httpHandler != null && applicationThread.servletInfo != null)
try
server = applicationThread.httpHandler.request.getApplication().getApplication().getServer();
catch(Throwable t)
System.out.println("caught exception while getting the server instance " + t.getMessage());
t.printStackTrace(System.out);
It looks like this method expects a httpRequest, and would find null because I'm in the servlet.init()
(at least, that's my interpretation)
I tested my code (the remoteFacade.create()) inside of a jsp, and it worked...
So, the next logical question is:
Can I make EJB calls from within the init method of a servlet? (or more specifically from a struts plugin, which I believe should be more or less the same thing)
If so, do I need to take extra steps?
Again, any experience/help on this will be much appreciated.
Thanks,
Christophe.

Error -50400 occurred at Invoke Method: FIFO.Read in Host.vi

Hey there,
we have sensors on an Engine which are connected to a NI cRIO 9014 board (with a NI9411 6-channel digital input modul) and go from there via network to a host computer.
cRIO board: the cRIO board collects the data from the engine and stores it in a buffer, this is because the network is to slow for the magnitude of data
host computer: the host computer reads over the network the buffer on the cRIO board, on the host computer it takes out specific portions of the data to create pressure graphs of the engine
Error:
Error -50400 occurred at Invoke Method: FIFO.Read in Host.vi
Possible reason(s):
The transfer did not complete within the timeout period or within the specified number of retries.
This error occurs in the following scenario:
- engine is running
- cRIO is running
When I press the start button (boolean 3) in the host.VI to start the reading of the data from the board AFTER I pressed the run button of the host VI.
The Error would not occur if I pressed the start button (boolean 3) BEFORE I pressed the run button of the host VI.
We tried to increase the time out, but it still did not work, the error occurs!
We would be really happy if you could look over it and help us in this case! If you need further informations or if we need to clarify some specific portion, please let us know!
We included the VI's in the attachement!
Thanks in advance!
Solved!

Chrisse,
There are a few things wrong in your application, if I may offer some suggestions.
First, your while loops are not running in parallel. In fact, they are in while loops with a true constant wired to them. I am not sure if this is by design for debugging, or on accident. I would put the Polling(read pulling zero elements) outside your main while loop.
Your second nested while loop (the one polling the # of elements and then pulling them out) is going to run just once, and may pull only a few samples. I don't think that is what you are looking for here, and there are a couple ways we can go here. You could continuously poll until you have 0 elements available for x amount of time, then you know you have no more samples available and you can process all the data OR you can put all of your data processing as part of that loop and just always write to file immediately as x samples are pulled.
Also, your main loop's stop condition is (i <= 3) Therefore, it will run once and then stop. Maybe you mean >=3?
Also, you have 'append to file' disabled on your write to spreadsheet, so everytime you write you are overwriting old data. If you want to continuously write, you will be losing data. This can be cured by either setting this to true(requiring a new file name or programatically deleting the old spreadsheet every time you run the vi) OR you can collect all of your data in a shift register, and only write to file once you have all your data available.
The error you are seeing is because you try to close your FPGA reference twice. You only need to close it once.
After seeing your overall picture, I think this can all be cured by simply hardwiring your Read to get your 1440X4 elements, but as we have seen, this does not work. Something is happening in your system....this is what I want you to do...run just the following code...and let me know how many elements remaining it gives you...Once the number has settled(I hope it does and your engine doesn't keep running), hit stop, and all the values will be put on a graph for you. My broken wires are because I do not have the FPGA VI.

Facing problem in creating socket in a method from an already deployed application exe while same method is working from another exe from same environment from same location.

Dll Created In: - MFC VC
6.0
Application Exe Developed In:
- VC 6.0, C# and VB.net (Applications which are using dll)
OS: - Windows XP sp2 32bit
/ Windows Server 2008 64 bit
Problem: - Facing problem in creating socket
in a method from an already deployed application exe while same method is working from another exe from same environment from same location.
Description: - We have product component which
has an exe component and from exe we invoke a method, which is defining in dll, and that dll is developed in MFC VC6.0. In the dll we have a method which downloads images from another system after making socket connection. But every time we are getting Error
code 7, it is not giving desire result while same method is working from another exe from same environment from same location. And also me dll is deployed on many systems and giving proper output from same application.
Already Attempt: - Because error is coming on
client side so what we did, we created a driver in C# which invokes same method from same environment(on client machine) using same dll and we are astonished because it worked fine there.
Kindly Suggest: -
We are not able to figure out root cause because nothing is coming in windows event logs but what I did, for finding the problem line, I wrote logs on each line and found the exact line in application exe which is not working,
actually it is not executing Create () method,
I will give snippet of the code for understanding the problem because we are not finding any kind solution for it.
Kindly assist us in understanding and fixing this problem.
Code Snippet: -
Int Initialize (LPTSTR SiteAddress, short PortId)
try
CClientTSSocket *m_pJtsSockto;
m_pJtsSockto = new CClientTSSocket;
LONG lErr = m_pJtsSockto->ConnectTS(csIPAddress,PortId);
ErrorLog (0, 0, "--------ConnectTS has been called ------------","" );
catch(...)
DWORD errorCode = GetLastError();
CString errorMessage ;
errorMessage.Format("%lu",errorCode);
ErrorLog (0, 0, "Image System", (LPTSTR)(LPCTSTR)errorMessage);
return IS_ERR_WINDOWS;
Note: -
CClientTSSocket extends CAsyncSocket
IS_ERR_WINDOWS is a macro error code which value I found 7.
LONG ConnectTS(CString strIP, UINT n_Port)
ErrorLog(0,0,"ConnectTS is calling Create [is going to call]","");
if(!Create())
ErrorLog(0,0,"ConnectTS is calling [Create not called successfully] ","");
n_Err = GetLastError();
ErrorLog(n_Err,0,"ConnectTS is calling1111111111111111Erorrrrrrrrrrrrr","");
return NET_INIT;
ErrorLog(0,0,"ConnectTS is calling2222222222222222222","");
if(!AsyncSelect(0))
n_Err = GetLastError();
return NET_INIT;
if(!Connect(strIP,n_Port))
n_Err = GetLastError();
ErrorLog(n_Err,0,"ConnectTS","");
return SERVER_NOT_CONNECTED;
Code description: -
From
int GETImage_MT() method we call Initialize() method and pass client machine IP and Port and there we call
ConnectTS() method, In this method we Create() method and finally it returns the error code as mention in macro 7.
Logs after running the program: -
--------ConnectTS has been called ------------
ConnectTS is calling Create [is going to call]
Image System
0
Note: - According to logs, problem is coming in Create method().
Here 0 is errorMessage received in catch block. And from catch block it returns macro value 7. And when we run same method individually from same machine, same environment through same dll
from different exe, it is working fine and we are facing any kind of problem. While same problem application was working properly earlier but now continuously it showing problem.
Kindly assist us to resolve the issue.

Pointer variable was already initialized; I have mention in code; kindly assist us.

How can I invoke the web service manually in websphere?

Hi
I've developed a webservice application using Rational Application Developer (RAD). I deployed it in a websphere 6.1 application server, using the administration console to import the war file that I had previously exported with RAD.
My webservice application is listed in the "Enterprise Applications" section of websphere's administration console as started.
My question is: how can I invoke the web service manually? Is there some kind of websphere generated webpage that I can use to call it manually?
I tried http://<server:port>/<contextroot> and http://<server:port>/<contextroot>/<servicename> in a webbrowser, but it doesn't work. Is it possible to invoke the web service manually, or do I need to develop a client?
Thanks in advance
Pedro

Hi Bo Wang,
    Go to the Portal -> System Administration -> System Configuration
                           -> Portal Content folder
                           -> Open Visual Composer folder
    There you can see the Webservice Systems you have created through VC.
You can delete the unwanted system here.
Regards,
Shemim

<Utils> <buildFacesMessage> ADF: Adding the following JSF error message: Cannot invoke method multiply() on null object
any help please ?

Thanks Frank ,
really i've already downloaded the ZIP of the final application , but the same error message ,
when removing the Annual salary ( Which is a new Attribute ( not DB column) Salary * 12 ) every think is fine and no more error message ,there is no null salary all the employees have a salary , my JDeveloper Version is 11.1.2.1.0
also , because of the EmpDetails is based on the query
FROM EMPLOYEES Employees, DEPARTMENTS Departments
WHERE Employees.DEPARTMENT_ID = Departments.DEPARTMENT_ID
and the Department id is non editable value , that means even if you add a new user u cant never check this user in this interface , u can check this user only on DB (SQL) level .

How can we call methods of one web dynpro component in another one

Hello Team,
How do I call one Web Dynpro component methods in another Web Dynpro component.
How do we use public parts.
thanks

Hi,
You want to use Comp2's getData() method in Comp1
If both the WebDynpro components are in the same DC:
1. Create a wrapper method (with the same signature) in the Comp2's Interface controller. And invoke the Component contorller's getData() method in this method using the below code.
wdThis.wdGetComp2Controller.getData()
2. Now Go to the Comp1 and right click on UsedWebDynproComps and add this Comp2 as a UsedWebDypro component.
3. Now go to the Component Controller of Comp1 and in properties tab add the usage declaration of Interface controller of Comp2.
4. Now using this below code you can access the method of InterfaceController of Comp2.
wdThis.wdGetComp2Interface().getData();
If both the WebDynpro components are in different DCs:
1. Right click on Comp2 and select Add to public part on Comp2 in DC2.
2. Now Add this public part in DC1 UsedDCs.
Now repeat the above stpes 1...to..4. of "If both the WebDynpro components are in the same DC" same.
Regards,
Charan

Can't invoke a process control from a pageflow

I create a simple pageflow that invokes a process control (jpd file) to start a
business process. I created a process control from the jpd and added it as a control
to the pageflow. I can run the process indepedently in the test harness, but cannot
invoke from my pageflow.
Any ideas what what could be wrong?
When I invoke a method on the process control I get the following in the test
browser:

Some additional information:
The problem seems to be related to a custom object that I am passing to the exposed
clientRequest(String, CustomObj) method in the process control. If I remove the
CustomObj parameter, all works fine. Unfortunately, I need to pass that object
to the workflow. I have the CustomObj define within my project "Project/com/omeninc/package/CustomObj",
my process file located at "Project/processes/customerNeed/SubmitNeed.jpd" and
my pageflow define at "Project/pageFlows/customerNeed/customerNeedController.jpf".
The entire project builds without error, but when I run it I get the ClassCastException.
Thanks in advance for any assistance!!

Invoking methods via java.lang.Method.invoke().

I need to invoke the getter methods that I have defined for a Trade object passed as an argument.
I am getting the excepion : java.lang.IIlegalArgumentException: wrong number of arguments.
This is the first time I am invoking methods this way.
Am I correct to assume that methods on an object can be invoked in this way?
How can I invoke the getter methods of the trade object.
Please help.
public void displayData(Trade trade){
     Method[] m = trade.getClass().getMethods();
     for(int i=0;i<m.length;i++){
          if(m.getName().startsWith("get")){
                    try {
                         m[i].invoke(trade, new Trade[] { trade });
                    } catch (IllegalArgumentException e) {
                         e.printStackTrace();
                    } catch (IllegalAccessException e) {
                         e.printStackTrace();
                    } catch (InvocationTargetException e) {
                         e.printStackTrace();

The getter methods of the trade object require no arguments.
The three getter methods of the trade object are:
getTradeId();
getProductId()
getReferenceId()Read the Javadoc; use it like this:
m.invoke(trade);

Can't invoke method on a co-deployed bean
