[aspectj-users] Questions around load time weaving (LTW)

[Mikael Petterson <mikaelpetterson@xxxxxxxxxxx>]

Hi Andy,

Thanks for your really good support.

I realized that I might need to use LTW for using my library (containing the aspects) with different java apps.

The reason for it is that we need an easy way to enable/disable aspect as well as only use a subset of them.

Therefore I have a couple of questions:

1. Is it possible to set other parameters from aop.xml and send values to aspect. I mean as runtime values?
   
2. Can the aop.xml reside in the META-INF folder on the java app? Will it override if I have a default one in the same directory but in lib?
3. I want to be able to set a directory path where all data from "Pointcut" will be stored. Is it possible to set it at runtime ( not using a system property)?
4. Do I only need the following for compiling the app:
    <configuration>
   
                       <argLine>-Xms512m -Xmx2048m</argLine>
   
                       <!--  AOP: Load-Time Weaving  -->
   
                       <argLine>-javaagent:"${settings.localRepository}"/org/aspectj/
   
                           aspectjweaver/${aspectj.version}/
   
                           aspectjweaver-${aspectj.version}.jar
   
                       </argLine>
   
                       <useSystemClassLoader>true</useSystemClassLoader>
   
                       <forkMode>always</forkMode>
   
         </configuration>
   
   and of course a dependency to the library containing  the aspects?

Your advice is greatly appreciated.
