[aspectj-users] DI Constructor issue

[Yetti <elliot.trussell@xxxxxxxxxxxxx>]

Hi,

Ive just started using aop for some simple logging in a new project. Ive
read through quite a few threads and various sites but cant seem to quite
understand why Im getting the problem.

I am using Spring 2.5.5 to inject various classes for a JMS project and also
using the schema based spring-aop namespace due to being restricted to
1.4jvm. I am also using aspectJ 1.5.4.

The problem is that although logging seems to work fine for any classes that
use a default constructor, classes that have constructors with args; 1. dont
get logging and 2. throw an error within the DI that seems to be a
nullpointer issue, Im only guessing at this as no info is given.

What I also dont understand is that I am using the method pointcut pattern
so why is this causing a problem with the constructor?

Heres my code, Hope Im not just being dumb (though most likely!)

<bean id="sonicConfig"
	
class="com.homeserve.guidewire.plugins.messaging.edi.outbound.transport.SonicConfig">
		<constructor-arg
value="SonicBroker=tcp://hgbsmdev02.hgb.hs.int:2531;SonicUsername=Administrator;SonicPassword=Administrator"
/>
</bean>

	<bean id="aopLogging"
	
class="com.homeserve.guidewire.plugins.messaging.edi.logging.LoggingInterceptor">
	</bean>
		
	<aop:config proxy-target-class="false">
		<aop:aspect id="aopLoggingAspect" ref="aopLogging">
		
			<aop:pointcut id="loggingPointCut" 
				expression="execution( *
com.homeserve.guidewire.plugins.messaging.edi.outbound..*.*(..))" />
					
			<aop:around method="aopLogging" pointcut-ref="loggingPointCut" />
			
		</aop:aspect>
	</aop:config>

    public SonicConfig(String sonicConnectionString) throws ParseException
    {
        this.sonicConnectionString = sonicConnectionString;
        parseSonicConnectionString();
    }

public class LoggingInterceptor {
	
	public Object aopLogging(ProceedingJoinPoint pjp) throws Throwable{
		Logger log = Logger.getLogger(LoggingInterceptor.class);
		Object retValue = null;
		Object[] args = pjp.getArgs();
		try	{
			
			StringBuffer entering = new StringBuffer();
			StringBuffer leaving = new StringBuffer();
			Signature sig = pjp.getSignature();
				String clazz = pjp.getSignature().getDeclaringType().getName();
				entering.append(clazz.substring(clazz.lastIndexOf(".")+1,
clazz.length()));
				entering.append(".");
				entering.append(sig.getName());
				entering.append("(");
				leaving.append(entering.toString());
				for (int i = 0; i < args.length; i++) {
					if (i > 0) {
						entering.append(", ");
					}
					entering.append(args[i]);
				}
				entering.append(")]");
				SourceLocation sl = pjp.getSourceLocation();
				log.info("Entering [" + entering);
					
			retValue =  pjp.proceed();

			leaving.append(")");
			log.info("Leaving [" + leaving + " Return value: " + retValue);
						
		}
		catch (Exception e)
		{
			log.error(e);
		}
		return retValue;
	}
}

Thanks 
Yetti
