Later I upgraded to JBuilder 2006 and uninstalled JBuilder X. I tried executing the .exe I built with JBuilder X and got a dialog saying it couldn't find the java runtime. C:BorlandJBuilder2006jdk1.5bin is in my path, but the runtime from JBuilderX is not anymore. How does the native executable go about finding java.exe (or javaw.exe)?

I believe it looks under "HKEY_LOCAL_MACHINESOFTWAREJavaSoftJava Runtime Environment" in the registry. Check out that registry entry and make sure it's properly set up. If it isn't, reinstall JBuilder or install a JRE from Sun's web site to get it properly configured. You can also tweak it manually if you're confident enough. -- Kevin Dean [TeamB] Dolphin Data Development Ltd. http://www.datadevelopment.com/ NEW WHITEPAPERS Team Development with JBuilder and Borland Enterprise Server Securing Borland Enterprise Server http://www.datadevelopment.com/papers/index.html Please see Borland's newsgroup guidelines at http://info.borland.com/newsgroups/guide.html Back to top Steve Guest Posted: Fri Nov 04, 2005 3:15 pm    Post subject: Re: How does native exe find java.exe "Kevin Dean [TeamB]" <NkOdSePaAnM (AT) datadevelopment (DOT) com> wrote: Quote: Steve wrote: I built a native executable using JBuilder X.

Do you have a feel for if that's the standard way packages find the runtime versus just expecting it to be in the path? I didn't even know the runtime put that key in HKLM. I just check and it looks like JBuilder 2006 didn't put an entry in there for the jdk 1.5 that it uses. I've been looking at 3rd party "wrappers" that will wrap your executable jar in an exe and they all say they'll "look for" a java runtime and inform the user if one can't be found. Thanks.

As far as I know, that's the standard Windows way of location the Java runtime. Yes, my personal favorite pet peeve. When a JDK or JRE is installed on Windows, you get "stubs" for java.exe and javaw.exe that are placed into the windowssystem32 directory. These tend to be at the beginning of your path, so they always "win". These stubs go and dig in the registry to see what that HKLM key is pointed to, and then they use that. Problem is, I've seen all too many cases where those stubs and the registry keys get out of sync, and then the stubs barf with some weird versioning error, and you end up having to reinstall your JDK/JRE to fix it. -- Regards, Lori Olson [TeamB] ------------ Save yourself, and everyone else, some time and search the newsgroups and the FAQ-O-Matic before posting your next question.
