Re: looking for sample MBean code for tomcat 6
Hi Peter,
Thanks for sending the link. I guess what my real question was:
how would I get TC to 'declaratively' instantiate my MBeans ?
From the example, most of them has a main() method to instantiate and
register the MBeans to the platform MBean Server. What would you recommend
for TC , a servlet that loads on startup and within the init method it would
create and register the MBeans?
I am porting my MBeans from JBoss (embedding TC) and JBoss provides a
declarative method do so without the needs of a servlet. It is done by
creating a service archive (e.g. myservice.sar - containing a
jboss-service.xml [similar to mbeans-descriptor.xml] that declares the MBeans).
The JBoss container would then instantiate the MBeans via the MBean's start()
method.
public class Main {
public static void main(String[] args) throws Exception {
MBeanServer mbs = ManagementFactory.getPlatformMBeanServer();
ObjectName name = new ObjectName(com.example.mbeans:type=Hello);
Hello mbean = new Hello();
mbs.registerMBean(mbean, name);
System.out.println(Waiting forever...);
Thread.sleep(Long.MAX_VALUE);
}
}
Thanks
Frank.

Re: looking for sample MBean code for tomcat 6
--- HARBOR: http://coolharbor.100free.com/index.htm The best application server on earth --- Hi Frank, I played with this a long time ago, and I've completely forgotten what I did. When it comes to monitoring servlets (own code) I came to the conclusion that its very hard to top a web server and an admin web page behind a password... but ok thats why I didnt persue it. But there were 2 links in particular that I found very useful... http://oss.wxnet.org/mbeans.html which talks about general tomcat config your question is in there, the Mbean starts with a context listener. and this... http://www.netbeans.org/kb/articles/jmx-tutorial.html which is a JMX plug-in for NB... makes testing and just getting the formats right easy. and then on tomcat I vaguely remember having to set up DJava command lines so the TC would expose a port to Jconsole... I dont remember seeing XML config to explicitly start a Mbean, I remember seeing that EJB containers tend to automate all this for you but servlet containers tend to be a little more manual. Anyway I think armed with those tools, you'll be on your way. I rember seeing it work on TC 5.5 but I dont think much changes other than the location of common/lib Have fun hello, I am looking some sample MBean code for TC 6.0.. I was able to model some code after the source code (e.g. MemoryUserDatabaseMBean.java in the org.apache.catalina.users. package) .

Re: looking for sample MBean code for tomcat 6
Hi Frank,
you can add your Mbeans at following file
=== $catalina.base/conf/tomca5-mbeans.xml ==
bean
mbean name=Bean:type=Bean
code=test.MyBean
attribute name=name value=Peter/
/mbean
jmx-operation objectName=Bean:type=Bean operation=show/
mbean name=Bean:type=Bean2 code=test.MyBean/
jmx-operation objectName=Bean:type=Bean2
operation=setAll
arg type=java.lang.String value=Willy/
arg type=java.lang.StringGo to water/arg
/jmx-operation
jmx-operation objectName=Bean:type=Bean2 operation=show/
/bean
===
The Engine element at server.xml can load those MBean instance
declaration.
Server ...
...
Engine name=Catalina
mbeansFile=${catalina.base}/conf/tomcat5-mbeans.xml
defaultHost=localhost
jvmRoute=node01
...
If you implement a init(),start()/stop(),destroy() method your MBeans
also notified from
Engine Lifecycle :-)
Install your MBean Code at common or server classLoader.
=== common/classes/test/MyBean.java
package test;
public class MyBean implements MyBeanMBean {
private String name ;
public String getName() { return name ; }
public void setName(String name) { this.name = name ;
System.out.println(name) ;}
private String street ;
public String getStreet() { return street ; }
public void setStreet(String street) { this.street = street ;
System.out.println(street) ; }
public void show() { System.out.println(name + -- + street) ; }
public void setAll(String name , String street) {
this.name = name ;
this.street = street ;
}
}
===
=== common/classes/test/MyBeanMBean.java
package test;
public interface MyBeanMBean {
public String getName() ;
public void setName(String name) ;
public String getStreet() ;
public void setStreet(String street) ;
public void show() ;
public void setAll(String name , String street);
}
I test the example with tomcat 5.5.25.
I am hasn't tested with tomcat 6, but the insourced modeler code
seems also working!
Regards
Peter
Look at my old fixed issue : http://issues.apache.org/jira/browse/
MODELER-17
But I am not sure that that patch at 2.0.1 is complete ( jmx-
attribute element not exists)
