preloaded SystemLibraries and Resart des Servers
Hi all,
i use jco nativ (not JCA,) within an EJB to get Data from SAP System.
if i deploy my Application over NWDS, i become an exception , that means, that some libraries (sapjcorfc) has been already loaded in another ClassLoader. After that , i have to stop und start my appServer again, it takes a long time and impeded corporate work.
Has anybody an idea, how can i optimize it, so that, i do not need restart my server , after i deploey my ear-file ?
Best Regards
A. Büyükyilmaz
