String drl = sCompiler.compile(stream, InputType.XLS);
File out = new File("toto.drl");
PrintWriter pw = new PrintWriter(out);

Hy,
I try to use a rule and a decision node with a local variable :
<start g="14,195,48,48" name="start1">
<transition g="-33,-26" name="soumettre" to="soumettre"/>
</start>
<rules g="97,195,92,52" name="soumettre">
<fact var="candidat"/>
<transition g="-68,-18" name="to exclusive1" to="exclusive1"/>
</rules>
<decision g="251,191,48,48" name="exclusive1">
<transition g="-29,-18" name="to ok" to="ok">
<condition expr="#{candidat.getPlop() == true}"/>
</transition>
<transition g="-29,-18" name="to ko" to="ko"/>
</decision>
<state g="303,86,92,52" name="ok">
</state>
<state g="340,290,92,52" name="ko">
</state>But if i have just the rule, there is no problem but when i add the decision node i have the following error :

[Spring Integration] New message: "Using JBoss(4.2.0) with Spring and AspectJ"
by Bala krishnan
User development,
A new message was posted in the thread "Using JBoss(4.2.0) with Spring and AspectJ":

--------------------------------------------------------------
I have an application in which I'm trying to use AspectJ with Spring and deploy it in JBoss 4.2.0.
AspectJ is integrated with spring and is loaded via
<context:load-time-weaver />
in spring xml file. When I run the application in standalone, it works fine -- aspects are getting called.
However, when I deploy the application (as a war) in JBoss, aspects are not called. I think that the classes are also not weaved -- I've have enabled debug in aop.xml,
<aspect>
<weaver options="-debug -verbose -showWeaveInfo">
....
</weaver>
....
</aspect>
and logs(weaving related logs) are not printed when I run the application as war. However, I do get message that aop.xml files are loaded and aspects areregistered.
What should I do to make aspects called in this environment? I tried disabling tomcat specific classloader (setting UseJBossWebLoader and Java2ClassLoadingCompliance to "true" in jboss-service.xml of tomcat, but that also didn't work. I have also given "-javaagent" to jboss startup.
When I searched, one option given was to use application specific "context.xml" for tomcat and copy spring-tomcat-weaver.jar to tomcat classpath. However, I got a exception, saying logger class is available in two class hierarchies, when I tried this. Is this(having a context.xml) the correct way to solve the issue? How the whole thing will work if I have an EAR and a WAR inside that EAR (assuming that I want to weave classes inside and outside war)?
