Compile it and copy Person.class to GlassFish domain lib directory, restart the domain, and create a custom resource of type Person:
public class Person implements java.io.Serializable {
private String firstName;
private String lastName;
private int age;
public String getFirstName() {
return firstName;
}
public void setFirstName(String s) {
firstName = s;
}
public String getLastName() {
return lastName;
}
public void setLastName(String s) {
lastName = s;
}
public int getAge() {
return age;
}
public void setAge(int i) {
age = i;
}
@Override
public String toString() {
return String.format("Person firstName:%s, lastName:%s, age:%s",
firstName, lastName, age);
}
//TODO override equals and hashCode
}
To list the attributes and properties of the newly-created resource with GlassFish asadmin get command:
$ javac Person.java
$ cp Person.class $GLASSFISH_HOME/domains/domain1/lib/classes/
$ asadmin restart-domain
$ asadmin create-custom-resource --restype=Person --factoryclass=org.glassfish.resources.custom.factory.JavaBeanFactory --property firstName\="Jon":lastName\="Smith":age\=20 resource/person
To update the age property of the resource with asadmin set command:
$ asadmin get 'resources.custom-resource.resource/person.*'
resources.custom-resource.resource/person.property.age=15
resources.custom-resource.resource/person.property.lastName=Smith
resources.custom-resource.resource/person.property.firstName=Jon
resources.custom-resource.resource/person.enabled=true
resources.custom-resource.resource/person.factory-class=org.glassfish.resources.custom.factory.JavaBeanFactory
resources.custom-resource.resource/person.jndi-name=resource/person
resources.custom-resource.resource/person.object-type=user
resources.custom-resource.resource/person.res-type=Person
Command get executed successfully.
To look up the custom resource, resource/person, from a webapp, or Java EE application:
$ asadmin set 'resources.custom-resource.resource/person.property.age'=15
resources.custom-resource.resource/person.property.age=15
Command set executed successfully.
You can inject it into Java EE web component or EJB component class such as servlet, filter, web listener, interceptor, or EJB bean class:
try {
InitialContext ic = new InitialContext();
Person person = (Person) ic.lookup("resource/person");
} catch (NamingException e) {
throw new RuntimeException(e);
}
A Java SE remote client can also look up the resource:
@Resource(lookup="resource/person")
private Person person;
The following shows how to build and run the remote JNDI client, and the output:
import javax.naming.*;
/**
* A generic remote client for testing JNDI lookup.
*/
public class TestLookup {
public static void main(String args[]) throws Exception {
InitialContext ic = new InitialContext();
for(String name : args) {
System.out.printf("Looked up jndi name %s, got %s%n",
name, ic.lookup(name));
}
}
}
Note that both TestLookup.class and Person.class are in current directory and therefore are in the client classpath. Person class also implements java.io.Serializable to make remote access possible.
$ javac TestLookup.java
$ java -cp "$GLASSFISH_HOME/modules/*:." TestLookup resource/person

Looked up jndi name resource/person, got Person firstName:Jon, lastName:Smith, age:15
