WDDynamicRFCExecuteException

[Former Member]

I have developed a sample webdynpro application which we intend using on both desktop and mobile device (HP iPac using Pocket IE 2003 or similar device). The application functions when executed from the desktop and PC Emulator (using the additional URL parameter sap.session.client=PieClient) , but on the actual device I receive the follwing error message when the BAPI is called:

"com.sap.webdynpro.modelimpl.dynamicrfc.WDDynamicRFCExecuteException"

Any assistance is greatly appreciated!

Regards,

Joanne

Hi Joanne,

This problem is due to the communication problem between your R/3 server and WAS server. Check whther connection is working properly?

Also check that max. connections to R/3 exceeds or not.

The application does not function from the actual PDA device.

The application input screens are displayed when I start the application on the PDA device, but I receive the error message after I click the button to display the information resulting from the BAPI call. I do not receive an error stack trace on the device, just the message in the exception that is caught after the BAPI call. I am in the process of adding logging details to the application to see if this will reveal any other results.

Joanne,

Is it a very first call? The only thing I can imaging is authorization issues (i.e. PDA device does not pass necessary credentials for some reason). Could you verify this? Or this is not an issue here (just predefined user set for JCo connection)?

Hi Valery,

We are using a predefined user in the JCO connection, but since you mentioned it I was wondering if having a fixed IP address would make a difference? ( The PDA device has a server-assigned IP address, but the desktop will usually have a fixed IP address).

Joanne

[Former Member · Accepted solution]

Hmmm... Scarcely, I guess...

Anyway, as Armin mentioned complete stack trace will be very usefull. Sure it's hard to get it on PDA, but probably you may find it in log or catch an exception and print stack trace to file on server?

I am unable to obtain a trace on the PDA. The following is an extract of my code when calling the BAPI:

//Call BAPI

try {

wdContext.

nodeFixedasset_Getdetail_Input().

currentFixedasset_Getdetail_InputElement().

modelObject().

execute();

}

catch (Exception ex) {

ex.printStackTrace();

wdComponentAPI.getMessageManager().raiseException("BAPI call failed " +ex.toString(), false);

}

wdContext.nodeOutput().invalidate();

The only response I receive on the PDA is the output from the raiseException "com.sap.webdynpro.modelimpl.dynamicrfc.WDDynamicRFCExecuteException"

What have I coded incorrectly?

Thanks,

Joanne

Joanne,

Embed the following code into catch(){} block:

try
{
  final PrintWriter pw = new PrintWriter
  (
    new FileWriter("C:\my-error-trace.txt")
  );
  ex.printStackTrace( pw );
  pw.close();
}
catch (final IOException io) {}

Reproduce error, and post content of C:\my-error-trace.txt here.

The problem was resolved by adding the value "sap.authentication = true" to the application properties.

[Former Member]

how you " adding the value "sap.authentication = true" to the application properties."? can you show me step by setp?thks!

[Former Member]

Hi

Try executing the RFC within SAP GUI and see if you get a error. The problem could be with your RFC or the parameters that you pass to the RFC. Moreover the parameters have to be passed in caps for the RFC to execute correctly.

If still you get the exception just check if your ABAP program is active and no one is changing it. Then just restart your J2EE and see. It works.

Can you please post the complete stacktrace?

WDDynamicRFCExecuteException occurs when the RFC is not executing from your WebDynpro. Please check if there is any problem while setting the input values into the BAPI when you run it through your specified device.
