Just installed *only* the WebObjectsRuntime.pkg on Snow Leopard Client. That gave me all the ususal things (/System/Library/Frameworks and everything). Don't know what's missing - I got much more than I expected/wanted. After that I followed these instructions: http://wiki.objectstyle.org/confluence/display/WO/Programming__WebObjects-Web+Applications-Deployment-Mac+OS+X+Server That gave me a working installation except for the fact that I couldn't access my apps, and that turned out to be this problem: http://www.mail-archive.com/[email protected]/msg01818.html Good to know this works. What I really want is is for Tomcat deployment to work... /Anders Chuck Hill wrote: > On Mar 15, 2010, at 2:57 PM, Anders Peterson wrote: > >> Chuck Hill wrote: >>> On Mar 13, 2010, at 12:16 PM, Anders Peterson wrote: >>>> Hi, I'm just about to set up a new deployment server (probably not >>>> using plain Mac OS X 10.6, not Server), >>>> >>>> So far I've been experimenting with Tomcat, but I have a problem >>>> with web server resources. >>>> >>>> Can you, anyone, confirm that it is possible to install only >>>> WebObjectsRuntime.pkg, and not the other three? >>> Not sure what the "other three" are.
