Re: [aspectj-users] lauching applications from another one with load-tim

["Fabio Fagundes Silveira" <ffs@xxxxxx>]

Hi Matthew,

   Ok ... but how to get this working?  I just can get this working if I type: java -javaagent:xxx Test ... Therefore, I dont know how to load the other application (e.g. from App1.main) using a separate class loader ... :-(

  Would you please send me some hints (piece of code)?

Thank you,
Fabio

You may want to load you test application using a separate class loader, with it's own classpath. As each class is loaded it will automatically get passes to AspectJ.
