Re: [aspectj-users] webstart integration

[Matthew Webster <matthew_webster@xxxxxxxxxx>]

Fabien,

I confess that I have never used webstart
but understand what it does. It would seem that the monitor (com.sun.javaws.Main?)
is running your application (deploy.jar?) in a new JVM but _not_ using
the same options, including -javaagent. Does the webstart documentation
mention how to specify options for the application VM? Have you tried weaving
the application ahead-of-time instead?

Subject	[aspectj-users] webstart integration

Hi,

I'm trying to integrate aspectj in a webstart application. The
idea is to log some interesting behavior of the application
for security purposes.
Here is the relevant lines I use in a ant script file: 
<target name="dynamicWS" if="doWs">
                
                 <java
classname="com.sun.javaws.Main" fork="true">
                
                 
               
<classpath>
                
                 
               
                 <pathelement
location="${aspectj.home}/lib/aspectjweaver.jar" />
                
                 
               
                 <pathelement
location="${log4j.home}/log4j-1.2.14.jar" />
                
                 
               
                 <pathelement
location="aspect.jar" />
                
                 
               
                 <pathelement
location="${java.home}/lib/deploy.jar"/>
                
                 
               
                 <pathelement
path="${java.class.path}" />
                
                 
               
</classpath>
                
                 
               
<jvmarg
value="-javaagent:${aspectj.home}\lib\aspectjweaver.jar" />
                
                 
               
<jvmarg
value="-Xbootclasspath/a:${java.home}\lib\javaws.jar;${java.home}\lib\deploy.jar"/>
                
                 
               
<arg value="${runtimeParameter}" />
                
                 </java>
                
</target>
What it does: run the application
What it doesn't do: starting aspectj

If I remove the -Xbootclasspath line, it starts java WebStart
monitor, with aspectj, but the web start monitor seems to make
a Runtime.exec() call, and the application itself runs in
another jvm ... and the application itself runs without aspectj.
Any idea ?
