[aspectwerkz-user] Enhanced jar for prepared classpath

Hi,

I'm working on packaging the app with AW using prepared bootclasspath 
weaving option.
I tweaked InstallAnywhere project to generate enhanced jar file during 
installation,
but I realized we also need to support the case when only JRE is 
available.

I guess JDK is needed to generate enhance.jar since 
org.codehaus.aspectwerkz.hook.Plug requires tools.jar in the classpath.

So my question is when we need to generate enhance.jar file? If I 
bundle enhance.jar generated from, say, Sun JDK1.4.2_07, does it work 
with Sun JRE1.4.2_XX? What about different major versions, such as 
JRE1.4.1?

Thanks in advance,
