[Installation, Configuration & DEPLOYMENT] - Classloader question
by jeff.yuchang
Hi, I've read the JBoss classloader from this wiki http://www.jboss.org/wiki/Wiki.jsp?page=JBossClassLoadingUseCases.
And I tried to write a simple code to see if it worked as it described.
Firstly, I've wrote a very simple class, called Util. the code is:
| package com.company.util;
|
| public class Util {
|
| public String getResponse() {
| return "This response is from Application Server's library such as JBoss" ;
| }
|
| public String getRequest() {
| return "doNothing";
| }
|
| }
|
and package this class as a JAR, called util.jar.
I've written another class, called Util.
| package com.company.util;
|
| public class Util {
|
| public String getResponse() {
| return "This response is from web app's library" ;
| }
|
| }
|
and I package this class as util-webapp.jar
3).
I wrote a simple class, which call the Util class, as following :
| Util util = new Util();
| System.out.println("Util response is: [" + util.getResponse() + "]");
|
Belows are some scenarios that I deployed.
1.
1) put the util.jar in the JBoss_HOME/lib
2) put the util-webapp.jar in my war, and I deployed war in the $JBoss_home/server/default/deploy
Result: I've found that the application uses the war's jar, which is util-webapp.jar.
2.
1) put the util.jar in the JBoss_home/lib/endorsed
2) put the util-webapp.jar in my war, and I deployed war in the $JBoss_home/server/default/deploy
Result: It uses the util.jar in the endorsed folder.
3)
1) put the util.jar in the JBoss_HOME/lib
2) put the util-webapp.jar in my war.
3) I package the war in an ear, and then uses the isolated classloader, and "java2ParentDelegation=false",
Result, it still uses the util-webapp.jar
I dont know what I am doing wrong here, but it seems it doesn't work as the JBoss configuration wiki said, can someone shed some light on this.
Thanks in advance
Jeff
