@Configurable - can't make it work

[Goll97]

I am tyring to inject an object using aop, this is what i have, i know i am missing something, please help

object

@Configurable("user")
public class UserObject {
    private TestClassI testBean;
    public TestClassI getTestBean() {
        return testBean;
    }

    public void setTestBean(TestClassI testBean) {
        this.testBean = testBean;
    }  
}

xml set up

    <aop:spring-configured/>                          
    
    <bean id="testBean" scope="session" class="test.TestClass">
            <aop:scoped-proxy/>
    </bean>

    <bean id="user" class="test.domain.UserObject" scope="prototype">
        <property name="testBean" ref="testBean"/>
    </bean>

i added the spring-aspect.jar

what else do i need to do.

oh yeah, so now i call this from a inex.jsp

        UserObject user = new UserObject();
        TestClassI testclassi = user.getTestBean();
        testclassi.printThis();

i get a null point exception when trying to access the testclass

thanks for the help

Check out this link that explains how to get @Configurable working.

I would speculate that you haven't enable the LoadTimeWeaving correctly.

i get a null point exception when trying to access the testclass

Are u using Load Time Weaving or Compile Time Weaving ? Do u get weaving information on the console ? That should indicate whether your class gets weaved with the dependencies.

I've been documenting my experiences getting @Configurable working properly.
See this thread - it may have a clue or two:

wow great support guys,
thanks a lot
must be problem with the weaving, i am trying it, i will let you know what my results are once i got it working

[Goll97]

i got it working

woo hoo,

I had to spend few minutes to get Load-Time Weaving working with Tomcat.

what i did is I modified my Catalina file, added the following line to java option

-javaagent:"%CATALINA_BASE%\server\lib\aspectjweaver.jar"

I am using net beans so other option is to go to the runtime tab, right click on the tomcat server you are using and select platform tab, you can also enter javaagent in the vm parameter.

Any body know if the javaagent works with weblogic or websphere??

Are there any alternatives to doing this?? I am not feeling comfortable adding the javaagent.

Compile-time weaving does not require a javaagent.

The other option that I know is compiling classes using aspectj, but seems like you are relaying on yet on another framework you know? Is there another way??

Example would be great,

thank you

Hi Goll97,

I have been trying to run a simple logging around advice in tomcat but could not succeede. Is it possible for you to provide a sample war for me ? I am definitely missing something somewhere but unable to find it out. I have posted a thread (tomcat + aop not working) but no one responded.

[Goll97]

let check if you are doing every thing ok

did you include the following jar in you libs:
aspectjweaver.jar

I have in my tomcat server lib folder

did you add the following to your jvm options??

-javaagent:"%CATALINA_BASE%\server\lib\aspectjweaver.jar"
