java.lang.NoSuchMethodError:

[Former Member]

Hi all,

For retrieveing the current loggedIn user I have implemented the following code:

String strUser = WDClientUser.getCurrentUser().getSAPUser().getUniqueName().toUpperCase();

but when i am passing this strUser to a method which is taking it as Import parameter and executing the RFC it is giving some error as:

<b>java.lang.NoSuchMethodError: com/freescale/qlt_rfc_handler/components/wdp/IExternalQlt_Rfc_HandlerInterface.executeGetMetaData(Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;)Z

n my application I am getting the LoggedIn user by applying the code</b>

Detailed description of the error is:

java.lang.NoSuchMethodError: com/freescale/qlt_rfc_handler/components/wdp/IExternalQlt_Rfc_HandlerInterface.executeGetMetaData(Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;)Z

Hi Gurmat,

Re-import your model and restart your j2EE instance once because it seems that you parameters or signature of your RFC has been changed and thus not the updated one. This will be updated once you restart your j2ee instance.

Hi,

Check for the parameters in the method GetMetaData() on line number 366.

The string you are passing is in the correct form or not.

Gurmat,

Reload+Rebuild your DC and re-deploy. It will solve.

Hi,

This kind of problem may be beacuse of version mismatch. i.e, when you create appl in NWDS for 04 but try to deploy in 04s server or vice-versa. Check if that is causing the problem. Else try debugging the application.

Hi Hairni,

Thanks for the response...

I am creating the application in NWDS 2004s and deploying in the 04s server.

For debugging I have removed that code for fetching the loggedIn user and instead I hav hardcoded the strUser and now giving this value as import parameter in the execution of RFC it is working.

I am not able to trace out wats the prob.
