[Former Member]

Hi, All

I call the ChangeProductionServiceInterface.changeProduction() in an customized web service . recently the changeProduction() method throws NullPointerException as following.

===============================

java.lang.NullPointerException: while trying to invoke the method java.util.Map.keySet() of an object loaded from local variable 'props'

at com.sap.me.globalization.GlobalizationServiceProvider.retrieveUserContext(GlobalizationServiceProvider.java:29)

at com.visiprise.globalization.impl.DefaultGlobalizationServiceProvider.getUserService(DefaultGlobalizationServiceProvider.java:264)

at com.visiprise.globalization.GlobalizationService.getUserService(GlobalizationService.java:141)

at com.sap.me.production.ChangeProductionSOBean.validateItem(ChangeProductionSOBean.java:1411)

at com.sap.me.production.ChangeProductionSOBean.validateChangeProduction(ChangeProductionSOBean.java:119)

===============================

it sames that [GlobalizationService.getUserService("com.sap.me.globalization.LocaleSpecificTextResourcesGlobalizationService") ] throws that Exception.

Hello,

In general, it looks like a bug in the ME code and I recommend that you submit a ticket (please attach this response to the ticket if you submit).

As far as workaround for now: this defect shows up when trace mode is set to DEBUGGING (me trace level is setup with ME admin page). Try elevating the mode to something less verbose .

If you need a workaround to make it work even with the DEBUG mode enabled, I can give you a couple of approaches but those will require a code change on your side.

Thanks,

Mikhail

Hello,

thanks for your answer.

in last month, the web service function can be used without problem. recently, this problem happened.

is there any setting?

Hello,

On the surface it looks like it was there for a long time.

Could it be that someone has just enabled the DEBUGGING mode in the manufacturing admin page for ME?

Thanks,

Mikhail
