Hi Ralph,
 
I think you're making this complicated, but it depends a bit on the goal you're trying to achieve.
 
If it's a matter of getting a correct sequence and only starting Apache when Tomcat is there, you could use another method.
 
The way I did that was by checking if the file called "mod_jk.conf-auto" that Tomcat generated when starting. Once the file is there, you are sure you can start Apache.
 
I'm not sure if this mechanism still stands with the latest versions of Tomcat, though.
 
Anyway, the way I did this was create a script starting both servers. It's a DOS syntax, but the similar can be done on a UNIX system:
 
 
set JAVA_HOME=c:\your\java\home
set TOMCAT_HOME=c:\your\tomcat\home
set APACHE_HOME=c:\your\apache\home
call "%TOMCAT_HOME%\bin\startup.bat"
 
:loop
if not exist "%TOMCAT_HOME%\conf\mod_jk.conf-auto" goto loop
 
start "Apache" "%APACHE_HOME%\Apache.exe" -d "%APACHE_HOME%" -s -k start
 
That did the trick for me.
 
Hope this helps you a bit.
