Debugging Java code from c++ through JNI

I have c++ application calling java methods through JNI. From c++ when I call the java method through JNI how do I debug the java code? It would be of great help if I get to know the settings that I need to do. I am using VC 6.0 for C++ and JBUIlder 8 for JAVA application.OS used is Windows 2000.

Put
_asm { int 3 } to C code in the proper place and start your java application. When C code reaches this debug break it shows a dialog to attach the debugger. Attach C debugger and debug Java and C codes.

Error: ORA-03113 while executing complex java code from Oracle PL/SQL

Hi,
I am trying to execute a complex java code from Oracle PL/SQL. The classes were resolved successfully. But in the middle of execution, I am getting the following error:
ERROR:
ORA-03114: not connected to ORACLE
begin
ERROR at line 1:
ORA-03113: end-of-file on communication channel
Process ID: 13685
Session ID: 21 Serial number: 20
Is there a way to debug the Java classes loaded into oracle? Or is there any utility to find out why the connection was lost?
Regards,
Saravana

Hi Saravana:
You could use simply System.out.println(..) at your Java code and see the output at the .trc files generated for your Oracle session.
Or better than this adding Java Util Logging messages at your code, to see how to use JUL API at the OJVM please see this blog post [Using JUL API inside the OJVM|http://marceloochoa.blogspot.com/2007/11/getting-logging-entering-exiting-and.html].
Best regards, Marcelo.
PD: ora-0600 generally are associated with RDBMS bugs, but these bugs can be bypassed by replacing the code which throws the exception by other with a workaround.

Calling simple Java Code from 11g BPM

Hi,
I know this has been round the houses but I cant find a satisfactory solution for my scenario. I would like to call some simple java code from BPM (11.1.1.6). I guess I need to expose it as a service but it seems overkill to be via soap so any advice you can give would be much appreciated. Creating a jar that I can call somehow would be perfect.
This is my scenario:
- I am creating a Security POC for BPM
- The BPM Process is exposed as a web service and authenticated using SAML
- I am testing by calling the WS from OSB
- I want to be able to get the WLS Principal and display the username and the roles for the launching user, from within the BPM process
- This is possible using some simple weblogic client api code shown below
- So all I want to do is call this code from BPM somehow
- Anyone point me in the right direction ?
cheers
Tony
subject = Security.getCurrentSubject();
for(Principal p: subject.getPrincipals()) {
if(p instanceof WLSGroupImpl) {
groupList.add(p.getName());
} else if (p instanceof WLSUser) {
principal = p.getName();
}

Debugging ABAP Code From Within WebDynpro

Hi experts,
I would like to check whether i can debug ABAP code from within webdynpro if i m using a remote J2EE server.
So netweaver development studio is on my machine
J2ee server is on a remote machine
R/3 is also on another remote machine
Thanks.
Rgds,
Daniel

Hi Daniel,
One thing note here is
"You have debugging authorization in the ABAP Workbench in the relevant system.
Since debugging in the ABAP system via load balancing is not supported, you must reconfigure your JCO destinations so that the calls take place on a dedicated ABAP application server. For Web Dynpro, this is done in the Web Dynpro Content Administrator. In the destination maintenance, specify Single Server Connection as the Destination Type ".
Other than that ideally it works with j2ee and abap on diff systems.

Creating java code from a class diagram in JDeveloper

I have created a class diagram in JDeveloper 11.1.1.3.0. When I generated java code from the class diagram by right clicking on the class diagram->transform->same diagram->UML to Java, a .java file is generated with attributes and getters/setters, and also a .uml_cla file is generated. What is this .uml_cla file exactly and what is it used for? Also I have a package.uml_pck file that was created 3 times. I have a package of com.xxx.xxxx, and it put this package.uml_pck file in "com", in "xxx", and in "xxxx". Do I need to retain all 3 of these files in my project?
One more question related to this. When I change something in the java representation of the class diagram (i.e. a datatype), it updates the .java file that was generated from the class diagram, and it also works the other way...change the .java file and the java representation of the class diagram changes. However, the class diagram that the code was generated from does not change, nor does the mysterious .uml_cla file I asked about in the above paragraph.

This did work for me, with an exception. I have put the .java files generated from the class diagram in a different package from the .class_diagram file, the package.uml_pck file, and the .uml_cla file to keep the actual source code separate. When I modified the .java file and transformed the class diagram from java to UML, it created the package.uml_pck file and the .uml_cla files again in the same package as the .java file, and they show the update. The package.uml_pck file, and the .uml_cla file that were originally created and are in the separate package from the .java files were untouched, thus the class diagram displayed does not reflect the change either. Does this mean I should not, or cannot, separate these files, and that they all must be left in the same package? (the purpose of separating it in the first place was for ease of deployment since we don't want to deploy any of the class diagram files) Thanks!

Calling java code from oracle apps form

I've created my own java .class file and am attempting to call it from an oracle applications form. I am getting a runtime error while running the form, but I don't know what the error is because nothing is being reported to me.
I've created the .java file in JDeveloper, compiled it into a .class file, deployed it to a .jar file, and placed it on the application server in a directory that the CLASSPATH can see it. I've added it to the archive parameter of the appsweb.cfg file and see that the .jar file is being downloaded when the JInitiator of Oracle Apps is started.
I have also imported the .class file into the form via the Program -> Import Java Classes which resulted in PL/SQL package stubs created to call the .class methods.
When I run the form, the java code is activated on a triggering event, PRE-INSERT. There is no java bean item in a block or on a canvas anywhere. I dont' think I need there to be since I am simply using the java code to perform actions during PRE-INSERT, not to display anything on the canvas.
I have placed debug messages throughout my code and see that the error is occuring in the PL/SQL packaged stub at the line "JNI.GET_CLASS()" where the parameter to that call is the name of my class. I know it's erroring there because I am handling the "java_error" exception. I am displaying "ora_java.last_error" in the exception handling, but it is null.
I am at a loss as to determine why I am having problems and how to display an error. Any suggestions? I'm happy to outline my steps and problem in more detail if I have missed something obvious.
We are using Forms 6.0.8.21.3 with Oracle Apps 11.5.7.
Shane.

Shane,
Don't loose the heart. You have come too close to end.
The scenario you have mentioned is very unique and something which will fit more in the forms forum. So I think that was a sincere answer to help you and not a "pass the buck" card type game :)
You are lucky that you got Tapash interested into this issue, otherwise you see there is no OAF component involved out here.
I have an article promised to some of the guys but will follow this issue.

Executing a java application from c++ using jni

hi,
how do i execute a java application from c++ ?. it should behave similar to typing 'java abc.class' at the dos prompt.
i've done up till recognizing the method id. GetStaticMethodID(). I tried using CallStaticVoidMethod() but didnt work. are there any other methods i should be using?

Look at the source code to the "java" command that is included in the sources that come with the JDK. Since it is the exact code that is run when you type java at the command line, it should be close to what you want.
