Error when JCO.Sever is called twice

[Former Member]

hello guys,

i have implemented my on own JCO.Server. My own JCO.Server extends the class JCO.Server and is called by a function with a RFC destination from SAP.

When I call my JCO.Server twice with the same function parameters from SAP then my JCOServer does not work at all.

When I change the parameter content for my functions everything works fine only when I used the same parameter contents twice then my JCO Server does not show any reaction at all.

Any ideas?

I myself can only gess. I implemented my own JCO.Server as well and never encountered any problems, but this seems to be a kind caching problem. Could it be that JCO or the RFC-technics in SAP caches the result to improve performance? As the import parameters are not changed the result should be the same...

Hello Daniel, I have never read from any chaning mechanism.

When you configure any RFC-Connection, there is no option for chaching. Thank you for your help anyway. Maybe you have got any other ideas?
