Hello all,
I'm having a unique problem with the proceed() call inside of an
around() advice. My problem is that when execution reaches the proceed()
call I get an error that a class is not found, even though the class is
contained in the same file as main(). I have tried manually adding that
specific class to my TOMCAT_CLASSPATH variable and the program will run, but
then weaving does not take place. The real bugger here is that I am running
a custom Tomcat which has several startup and variable scripts. If I run my
program on a normal Tomcat instance everything works fine, it is only this
custom Tomcat that gives me headaches. My best guess is that I have
competing CLASSPATH variables and that when proceed is called, it calls an
empty or near empty classpath variable. Any ideas?
Thanks for the help!

Here is the code I'm using:
ASPECT:
import java.util.Date;
public aspect TimerTest{
pointcut greeting():
execution(void com.alhadef.*.*(..));
after() returning() : greeting()
{
System.out.println(new Date() + " ASPECT: Exiting: " +
thisJoinPoint);
}
void around(): greeting()
{
System.out.println("DEBUG: In around advice");
long start = getTime();
System.out.println("DEBUG: start = " + start);
proceed();
System.out.println("DEBUG: proceed comlpete");
long timeTaken=getTime()-start;
System.out.println("TIMER: "+ new Date()+" "+ thisJoinPoint + "
took: " + timeTaken + "millisec." );
}
public long getTime()
{
return System.currentTimeMillis();
}
}
