RFC found in negative cache

[Former Member]

Hello all,

I had an RFC model connected to my WD component.

I erased the model from my component (it is still being used in another component).

everything was working fine for a few month until today.

today the following exception appeared (without any changes to the code):

java.lang.classNotFoundException: <rfc name> found in negative cache

p.s. the RFC still works fine in the other component.

Does anybody knows what is the negative cache and how to erase it?

thanks in advance, Varda.

Varda,

It is class loading issue.

Try restart your server.

If problem persist, it is necessary to revisit references to model classes (if they are located in separate DC)

Hi Valery,

thanks for your reply.

we restarted the server (assuming that you meant the portal server) but it didn't help.

what do you mean by: "it is necessary to revisit references to model classes"

we checked again and this model is no longer one of this component model classes.

thanks, Varda.

Varda,

Then please describe how many DCs are you using (previously and now), where RFC model was located (what DC), what references you had/have between DCs.

Hi Valery,

I have the same problem.

How did you solve it ?

Thanks.

David,

Most probably you have wrong run-time references between your DC(s) and/or standard SAP libraries.

Hi Valery,

In my WD app, I do not use DCs. I created directly in the class models all my RFC models.

Can it be a problem ?

Thanks.
