Is it possible to use java from host from within wine? The obvious answer is no - must install the windows version. However, I am wondering whether a symlink to the hos java folder (or similar trick) would work, considering that jva is a VM. I mean, does java really care what environment the request came from? Second question is re WINEPREFIX, and whether such a setup is possible: Let's assume I have dotnet40 and all dependents installed in .wine-dotnet. Let's then try to install some dotnet dependent software in a separate prefix so as not to contaminate our working dotnet pool. Set the prefix as .wine-someapps and link the dotnet dependencies to the first prefix, install as normal - any additions go into the second prefix. Answer to both questions will probably be NO, but I'll ask anyway. Regards.
