WO5.2 and optimizeit: Class com.webobjects._bootstrap.WOBootstrap not found.

[j-rochkind at northwestern.edu (Jonathan Rochkind)]

I don't really understand what's going on, but it MAY have something to do 
with seperate class loaders. I don't really understand how this works in 
Java, but there are (potentially) different class loaders, and WOBootstrap 
uses it's own class loader, and maybe this is causing a problem for 
OptimizeIt?  But I'm not really familiar with OptimizeIt myself.

So you could try NOT using WOBootstrap. WOBootstrap is new in WO 5.2---you 
can still launch apps the old way, without WOBootstrap.  When you launch an 
app in PB with WOBootstrap, you'll see the "generated classpath" output in 
the console.  You could use this entire list as the classpath for your 
OptimizeIt launch, and then 'Application' is the initial class, rather than 
com.webobjects._wobootstrap.WOBootstrap.  This is the way I launch things 
with bugseeker2, my debugging software. Works for me. It's worth a try.

Keep in mind the way the class path works: you need to actually list the 
specific JAR's involved, you can NOT just list a directory that contains 
JARs. Java classpath doesn't work that way. If you list a directory in the 
classpath, any .class files in that directory will be included in the 
classpath, but NOT any .JARs in the directory. JARs must be listed 
explicitly one by one with their complete path.

Good luck,
