Thanks guys! This actually worked... I posted a earlier post on the JSP forum that I was having difficulty compiling a JSP file with Subversion on my OS X Tiger. Well, I think that its because that the particular version (5.0.28) of Tomcat which I was using didn't support JDK 1.5 (it even says on the jakarta.tomcat.org URL that Tomcat 5.5.9 is the one that is expected to be used for JDK 1.5) and also conflicted with a dynamic library in Subversion.
Well, now Subversion 1.2.0, JDK 1.5, and Tomcat 5.5.9 are fully operational on my PowerBook!
Also, for some odd reason, the sh startup.sh does work! I can start or shutdown tomcat by using sh or ./
What's weird is that the war file from my project actually did work on my WinXP machine running JDK 1.5 and Tomcat 5.0.19.
