Re: FW: [aspectj-users] AspectJ with weblogic application server6.1!!!
|
Sharath,
The "-javaagent" is a Java 5 feature along with the java.lang.intrument API
that is used by AspectJ. You should use the JRockit agent instead under BEA
which I believe is available at the 1.4 level. See
http://www.eclipse.org/aspectj/doc/next/adk15notebook/ltw-agents.html.

Subject: FW: [aspectj-users] AspectJ with weblogic application
server6.1!!!
Dear All,
Installed 'aspectj-1.5.0_M3a.jar' and executed sample program in command
line and it is working fine with 'pointcut'.
I'm running BEA weblogic6.1 application server with JDK(j2sdk1.4.2_07)
version. Following changes are carried before starting application server.
1. Added 'C:\aspectj1.5\lib' to CLASSPATH.
2. Added 'C:\aspectj1.5\bin' to PATH.
3. Added '-Daj.weaving.verbose=true' and
'-Djavaagent=C:\aspectj1.5\lib\aspectjweaver.jar' options while starting
app server.
When I added ‘-javaagent:aspectjweaver.jar’ to the starting app
server command it is throwing following error:
Unrecognized option: -javaagent:aspectjweaver.jar
Could not create the Java virtual machine.
4. Compiled programs with below command:
ajc -d
C:\bea\wlserver6.1\config\isri\applications\isriapp\web\WEB-INF\classes
-classpath "C:\ISRI Restructured\isriapp\web\WEB-INF\classes;C:\ISRI
Restructured\lib\*.jar;C:\ISRI
Restructured\lib\vendorclasses.jar;%CLASSPATH%" TestManager.java
TestAspect.java
-----
Application server is started fine but it is not showing ‘pointcut’
information after executing ‘TestManager.getIP()’ method. Please find the
source programs in attachment. Please let me know, how to create aop.xml
file for these programs? Whether ‘jdk1.4’ is supported by aspectj? How to
enable pointcut for this scenario?
Thanks in advance.
Sharath.

This is not available in M2
It is not available neither in the last development build from
http://www.eclipse.org/aspectj/downloads.php (june 20)
so you 'd better wait (else checkout the cvs and build the whole yourself).
Anyway since I assume there will be a build updated soon here are the
steps that you would need - for further reference:
- change your weblogic startup script so that it starts with
aspectjweaver.jar in its classpath and with the following option
(assuming you are using JRockit):
java ...... -Xmanagement:class=org.aspectj.weaver.loadtime.JRockitAgent
- write and compile your aspect, place it in the classpath
- write an aop.xml file and have it in a somepath/META-INF/ folder,
with somepath a folder that is part of your classpath (I assume you
want to enable the weaving for the whole app server, else you would
have to pack this file in your deployed application)
The following options might be handy
-Daj.weaving.verbose=true (JVM option, in the startup script)
and
<weaver options="-verbose"> in the aop.xml file
Read more about the aop.xml file for such a scenario here
http://eclipse.org/aspectj/doc/next/adk15notebook/ltw.html
Once again, all this will be available in M3, so I would advise you to
wait or look for more support around the dev2dev extension you found
on BEA newsgroups.
