No ManagedResource attribute found for class

[Shirish]

HI ,

I am trying to register a simple spring as JMX bean through springs framework.
How ever its throwing the following exception

org.springframework.beans.factory.BeanCreationExce ption: Error creating bean with name 'exporter' defined in file [C:\bea91\user_projects\domains\mydomain\mbeans-wls.xml]: Initialization of bean failed; nested exception is org.springframework.jmx.export.metadata.InvalidMet adataException: No ManagedResource attribute found for class: class ConfigurableBean

I have used commons metadata attribute style .

Any help would be great.

Thanks..
Here is the code snippet for the bean

import java.util.ArrayList;
import java.io.Serializable;
import java.util.Properties;

/**

* log=true, logFile="jmx.log", currencyTimeLimit=15, persistPolicy="OnUpdate",
* persistPeriod=200, persistLocation="foo", persistName="bar")
*
*/
public class ConfigurableMapBean implements Serializable{

private String name;
private String template;

private Properties properties;



public ConfigurableBean(){}
public ConfigurableBean(String name, String template)
{

this.name=name;this.template=template;
}

/**

public String exposedOperation(String msg){return "Hello ! "+msg;}



/**

public String getName(){return this.name;}


/**

public void setName(String name){
System.out.println("Setting new name "+name);
this.name=name;}

/**

*/
public String getTemplate(){return this.template;}


/**

* (description="The Template Attribute", currencyTimeLimit=20,
* defaultValue="bar", persistPolicy="OnUpdate")
*/
public void setTemplate(String template){this.template=template;}


public Properties getProperties(){return this.properties;}

public void setProperties(Properties props){
System.out.println("Setting new name "+name);
this.properties=props;


}




/*public void init() throws Exception{

System.out.println("Init called ");
setName("SARA");
setTemplate("Template1");

cache.put("","CI", (Object)this);

}*/

public void destroy(){

System.out.println("Destroy called");
}

}

Make sure to compile your classes with the Commons Attributes compiler: http://jakarta.apache.org/commons/at.../compiler.html

[Shirish]

Thanks, will try that , since this was not working so in the mean time used Annotations which worked fine.

I would go for annotations if possible (you can use java 5) - they don't require any compilation step, they are strong typed plus declaring them is shorter.
