illegalaccesserror - metadatacache

[Former Member]

Hi there,

I've transported my webdynpro project developments to NWDI. There are 2 main components: bupa & interactions. Everything worked perfectly at the former project, but now only the interactions component works as it should. Everytime I want to run something from the bupa component, I get the following error:

java.lang.IllegalAccessError: tried to access method com.bdx.sap.bb.data.bupasearch.BuPaSearchModel.wdGetStaticMetadataCache()Lcom/sap/tc/webdynpro/modelimpl/dynamicrfc/DynamicRFCModel$MetadataCache; from class com.bdx.sap.bb.data.bupasearch.Z_Crm_Bb_Bupa_Search_Input

In my code/context/... there are no errors whatsoever...

What could be the problem? I reimported the models & restarted the server.

I even tried by setting the metadata JCO destination to "don't cache" in the WebDynproConsole under Adaptive RFC Metadata Cache Invalidation, but that didn't help..

Any help is highly appreciated!

Kind regards,

Allan

Hi Allan,

Does bupa component have any used components (Used DCs)? If yes, please check any of one of those used components or their models have changed. If they have been changed, they have to build and transport successfully.

Hi there,

Let me elaborate; I have 4 DC's:

-data DC: container for RFC models

-interactions DC: all coding concerning interactions is held here. Abovementioned data DC is one of it's used DC's

-bupa DC: contains all coding concerning business partners. Used DC's: data DC + interactions DC

-BB DC : container for main application (homepage) + navigation between DC's: Used DC's: data, interactions, bupa

Interactions DC works as it should, so that means the data DC also works as it should.

All DC's can be built successfully (with warnings).

Whenever you click one of the buttons which will lead to the bupa DC, I get an illegalaccesserror like mentioned in my first post..

Anyone who has already seen this before? What did you do to solve this issue? I'm running out of options...

Kind regards

Allan

PS, I work on NW04S 7.0.14, and the java stack is 7.00 SP14

NWDI is 7.00 SP15

Is there no one who has encountered such an error?

Hi Allan,

*java.lang.IllegalAccessError:

tried to access method com.bdx.sap.bb.data.bupasearch.BuPaSearchModel.wdGetStaticMetadataCache()Lcom/sap/tc/webdynpro/modelimpl/dynamicrfc/DynamicRFCModel$MetadataCache;*

from class com.bdx.sap.bb.data.bupasearch.Z_Crm_Bb_Bupa_Search_Input

refers to the bupa DC's model.

Can you check in the any of the model attributes left without binding or missed references?

(some times we don't get errors for this)

Try executing the Z_Crm_Bb_Bupa_Search RFC in R/3 whether it is working fine or not.

Hi Siva,

The RFC works fine.

Concerning model binding: all context nodes + attributes from the custom controller are bound to the model; all context nodes + attributes from the views are bound to the context from the custom controller, so that doesn't seem to be incorrect...

Maybe it's important to mention that the bapi's are created in CRM2007.

Kind regards,

Hi there,

I tried by copying the RFC FM to a new RFC FM which also works fine,

deleting old model + the entry in used models,

importing a new model based on the copied FM,

modifying all contexts,

modifying coding in order to use the new model,

building, ...

Now I get the same error, but based on the new model..

Is there someone (from SAP maybe?) who can shed a light on this really strange issue?

Kind regards

Allan
