Debug into ejb
Hi,
Using Jdeveloper 9.0.3 I am developing an application with ejb's. I would like to debug into a ejb from a non-ejb file. How to do this when both the app and the ejb are running in the same instance of OC4J?
/Michael
hi,
start your OC4J-Instance with following flags:
java -ojvm -XXdebug,detached,port4000 -jar oc4j.jar
afterwards configure your project within JDeveloper (project settings): open debugger and click on remote; there you have to choose ojvm and confirm
that's it... put your breakpoints in your code and click on the uggly red bug in the toolbar; you will be asked the host and port of the OC4J, leave the host empty and the port at 4000
try it ;o)

I m not able to debug into a BADI, though I tried putting a break point in the include for the BADI as well as tried using
break-point 'MYUSERID'.
It still doesnt workbreak user will work . But are you sure that you have implemented correct BADI and it gets triggered in that transaction.
Sometimes it is not so easy to find a BADI method or user exit to implement at an exact momment of the execution of a program. Here is one of the ways that can be used to spot which BADI method or user exit should be implemented.
1. Enter SE24;
2. Enter the class name CL_EXITHANDLER;
3. Double-click the method GET_INSTANCE;
5. Set a break-point at command line CASE sy-subrc (near line 27);
6. Execute the transaction you want to analyse; It will stop at the break-point you have just set on class CL_EXITHANDLER when it finds any BADI method/Exit call.
7. On debug screen, type the field name exit_name. This field contains the BADI method/Exit name which is being called in the program on that momment.
8. Press F8 to see the next calls.

How to debug with EJB+Servlet+J2ME at the same time?
I am setting up an environment to compile Sun's Smart Ticket J2ME application. However, it run with application exception in the servlet or EJB. I tried to debug. But if I debug the servlet with Embedded AS in JDeveloper, I cannot debug the EJB since the EJB cannot deployed to the embedded AS. (EJB and Servlet must be co-existed in the same AS, at least using same JNDI)
So is there any good approach to debug?
email: [email protected]Hi Marvin,
If the EJB cannot be deployed to the embedded AS, then you should probably use remote debugging to debug the servlet and EJB in the stand-alone AS.
Look in the Help for topics about remote debugging the OC4J application server. (I'd give you the exact topic title, but I'm at home for the holidays and I don't have the latest JDev on this machine.)
The Help topic describes it in more details, but the basic steps are as follows:
1. Launch the AS in debug mode by inserting some debugging options on the command line used to start up the AS.
If you are using OJVM, then the debugging options are
-XXdebug,port4000,detached
If you are using another JVM (for example HotSpot), then the debugging options are
-Xdebug -Xrunjdwp:transport=dt_socket,server=y,address=4000,suspend=n
2. Set your project for remote debugging by checking the Remote Debugging checkbox on the Debugging - Remote panel of the Project Settings dialog. Also you should select the "Attach to OJVM" radio button if you are using OJVM or the "Attach to JPDA" radio button if you are using another JVM (for example HotSpot).
3. Click the debug button in JDev and enter the host and port where the AS is running (leave host blank if the AS is on the same machine as J[i]Long postings are being truncated to ~1 kB at this time. -
WebLogic 11g and Spring beens injected into EJB
All,
I am getting an error injecting spring managed beans into EJB's within WebLogic 11g. I am using an interceptor extending the SpringBeanAutowiringInterceptor to set the context name by overriding the getBeanFactoryLocatorKey method. This is configured within the ejb-jar.xml file as an interceptor-binding for all ejb's. The beanRefContext.xml is in the root of the ejb jar and on the class path.
The application deploys however when I can the remote ejb interface the following error occurs. The remote interface and model passed on the method call are deployed within a ejb-client jar file that within both the ejb and web applications class path. The ejb and web app are deployed separately i.e. the web app is deployed as a war out with the ejb ear.
Does anyone have an idea on what is causing this? I suspect it is something to do with the class loaders / classpath and where the sping managed context is being loaded from. The Spring jars are deployed within the root of the ear and referenced within the Class-Path manifest.
Regards
Neil

Debugging into EntityManager source code
Hi,
I often want (need) to debug into persist and other methods instead of skipping over them , as the error often happens in there, and as the framework provides very poor error reporting, I need to be able to debug to the error myself. Is there any way I can configure JDeveloper to debug into the source of the ADF/JEE framework?
thanks
ROK, I take it back, the error reporting in JDeveloper is truly exception. The best ever. May I now have some help please? :P

Debug into request- get_form_fields
I am just curious:
When I debug my BSP application, it is not posible to debug into request->get_form_field. Instead, the debugger just jumps over this method.
There are some other messages as well, that you cannot debug into, e.g. in the class CL_HTMLB_MANAGER.
Are these methods special in some so that you cannot debug into them?I debugged class CL_HTMLB_MANAGER so many times. I didnt face any problem.
For example in below code put a break-point in GET_EVENT_EX & execute the BSP Application. You can able to debug the CL_HTMLB_MANAGER class.
EVENT ?= CL_HTMLB_MANAGER=>GET_EVENT_EX( REQUEST ).

How can I use PreloadSWF with files built with -compiler.debug into Flash Player 11.4?
I'm using Internet Explorer 9 on Windows 7 (x64) with a debug Flash Player (version 11.3.300.271 - I'm using the ActiveX plugin for IE). Using Flex SDK 4.5.1.21328A I compiled the ActionScript code
package MySample {
import flash.display.Sprite;
public class MyHook extends Sprite {
public function MyHook(): void {
super();
Into a `.swf` file by running the command
mxmlc.exe -compiler.source-path=. -output=MyHook.swf -tools-locale=en -headless-server=true -static-link-runtime-shared-libraries -compiler.debug -- Sample\MyHook.as
I then preload this by creating an mm.cfg file and adding an PreloadSwf entry referencing MyHook.swf; running all this in Flash Player 11.3.300.271 works fine; I can point my IE to some web page containing flash applets and my own SWF file is preloaded just nicely.
However, the most recent Flash Player release on Windows (11.4.402.265) breaks this. After updating the player, any flash applet triggers error message boxes from Flash player saying "Verify Error #1014: Couldn't find spark.components.Application". Clicking the error away opens the same message box, but with a few different type names.
The workaround I found was to remove the -compiler.debug switch from the mxmlc command line; doing so make things work with Flash Player 11.4 but alas trace() doesn't work anymore.
Does anybody know how PreloadSWF can be used to preload debug SWF files into Flash Player 11.4?Ah, thanks for making me aware of that forum - I didn't know about it. I now reposted the question at http://forums.adobe.com/thread/1068071 - this thread can be closed as far as I'm concerned. Should I mark your answer as being the resolution to my question or the like?

Extremely difficult to debug, about EJB, JSP
These codes are in a JSP page, an EJB will be looked up:
addcd.jsp
<%!
private CDAdder cdadder = null;
public void jspInit() {
try {
InitialContext ic = new InitialContext();
Object objRef = ic.lookup("CDAdderBean");
CDAdderHome home = (CDAdderHome)PortableRemoteObject.narrow(objRef, CDAdderHome.class);
cdadder = home.create();
} catch (RemoteException ex) {
System.out.println("Remote Exception:"+ ex.getMessage());
} catch (CreateException ex) {
System.out.println("Create Exception:"+ ex.getMessage());
} catch (NamingException ex) {
System.out.println("Unable to lookup home: " + ex.getMessage());
public void jspDestroy() {
cdadder = null;
%>
<%
HttpSession httpsession=request.getSession();
httpsession.setAttribute("cdadder",cdadder); //i want to add this object to the session so that i could retrieve it and use its methods in other JSP pages.
%>

<input type="submit">
</form>
......................................addtrack.jsp
<%
CDAdder cdadder=(CDAdder)request.getSession().getAttribute("cdadder");// get back the object in the session
String TitleOfTrack=request.getParameter("TitleOfTrack");
String DurationOfTrack=request.getParameter("TitleOfTrack");
cdadder.addTrack(new Track(TitleOfTrack,DurationOfTrack) ); //add the Track object into the arraylist using the addTrack(Track track) method in the CDAdderBean
response.sendRedirect(addcd.jsp); //redirect back to the addcd.jsp page
%>CDAdderBean.java
public class CDAdderBean implements SessionBean {
// data item to hold a reference to a passed Session context private SessionContext ctx;
private ArrayList tracks=new ArrayList(); << This arraylist holds the Track objects
public void addTrack(Track track) throws RemoteException{
tracks.add(track); //one method for adding tracks to the arraylist
public void removeTrack(int index) throws RemoteException{
tracks.remove(index); //another method for removing a track from the arraylist
public ArrayList getListOfTracksAL() throws RemoteException{
return tracks;
...............................Each time the user enters the required fields(title,duration) to add a track, these parameters will be passed to the addtrack.jsp, and the addtrack.jsp will retrieve the cdadder object from the session and use its addTrack method to add the track to the arraylist. And when it finishes, it will redirect back to the addcd.jsp. I got some other codes in the addcd.jsp(I did not show it as it will look very messy), anyway, the codes includes a call to the getListOfTracksAL() method which will return an arraylist of Track objects.
my problem is that, EVERY TIME i started the sun application server, and go to the addcd.jsp, then the FIRST TIME I entered all the required fields and click submit button . I expected the parameters would be passed to the addtrack.jsp and it would add the track to the arraylist for me and then returned to addcd.jsp and the addcd.jsp would display the track that I just tried to add.
but it didn't.
I am sure that it DID add the track to the arraylist because i tried to print the size of the arraylist after the addTrack method was invoked.
the most strange thing was that the addcd.jsp would display the tracks correctly after the FIRST TIME of adding a track.
Please take a look at this link if you have time:

the first time i tried to add a track, the addTrack method was really invoked and the size of the arraylist became 1
but when it returns to the addcd.jsp page the arraylist became empty
but the most strange thing was that, it worked correctly AFTER the first time.
thank you very much for your advice. -
Integrate Standalone Proxy into EJB-Module
Hello,
I want to integrate a webservice-call into a standalone EJB-Method.
Therefore I have created a standalone proxy DC and added public parts of type "assembly" and of type "compilation".
After creating a DC of type EJB-Module I reference the standalone proxy as used dc in my new EJB-Module project.
I CAN build the new EJB-Module DC. However when I look at the generated jar-file, the classes of the standalone proxy ARE NOT included.
Therefore (after generating a DC of Type EAR-Project) the deployment process returns with an error as referenced classes of the webservice proxy cannot be loaded. All EJB-Classes are included
in the EAR-File, but classes of the standalone proxy are missing.
Does anybody know in which way have to reference the webservice libraries (=the webservice standalone-proxy) so that they are included in my EJB-JAR-File?
PS: I don't want to replace the standalone proxy by a deployable proxy, if that is possible!
Thanks for your help!

Hi there,
How can I step into web dynpro component while debugging a process?
Regards,
Ricardo GiacominHi
1.Enable remote debugging(external breakpoint) on function module
2. Use same UserID that enables debugging and used in JCo Connection.
3. Run your application, it will take you to SAP GUI screen when breakpoint found.

This one is dfinitly misspelled in the help file, according to the online help it should be:
call dbms_java.grant_permission( 'WEROWE',
'oracle.security.JServerPermission', 'Debug', null);
or:
grant javadebugpriv to werowe;
both should do!!
Pretty annoying isnt it - wrong helpfiles
cost a lot of time!!

Debugging into sun's java sources
Hi,
this is propably not a very advanced question, but anyway:
How can I step into sun's original JFC-sources while debugging my swing-application? I suppose this would make it much easier to understand default behaviour of some comlpex objects like JTable.
Thanks in advance!Hi,
Try this:
1. When you start the debugger, choose View | Loaded Classes from the main menu to display the Loaded Classes window.
You will see classes listed by package. Those packages with tracing disabled, will appear with a red cirle and a slash through them.
2. You can expand the packages to get to subpackages or individual classes, then select Enable Tracing from the context menu to enable stepping into those classes.
By default, we disable tracing for sun, java, com, and oracle, because generally that's a lot of code to step through, and you generally will not have the source for those packages.
If there is no source available, we try to generate a stub for you.
