Today, i have a very weird condition, im installing Jboss EAP 6.1 but i cannot access its administration console from outside ip. Somehow, everytime i run netstat -aon command, i can see that port 9990 binded only with 127.0.0.1.
The workaround is actually very simple, i only add -bmanagement on JBoss start command,
./standalone.sh -bmanagement=0.0.0.0
And now port 9990 is accessible by other network.
Beberapa hari yang lalu, gw ditanya oleh salah seorang temen gw, Ariestania Winda. Dia nanya, gimana caranya bikin validasi login sederhana dengan Spring Security. Oke, berikut adalah tutorial yang gw kasih ke dia. Semoga bisa bermanfaat untuk yang lain.
Semua dimulai dengan konfigurasi maven sederhana, berikut pom.xml yang gw punya,
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Kemudian register konfigurasi spring di web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

</context-param>
<listener>

</listener>

<url-pattern>/*</url-pattern>
</filter-mapping>
<session-config>
<session-timeout>

</session-timeout>
</session-config>
</web-app>
Dan 3 xml milik Spring, ApplicationContext.xml, dispatcher-servlet.xml dan applicationSecurity.xml
<?xml version="1.0" encoding="UTF-8"?>

<user-service>
<user name="edw" password="123456" authorities="ROLE_USER" />
</user-service>
</authentication-provider>
</authentication-manager>
</beans:beans>
Lalu gw bikin satu java class sebagai controller,
package com.edw.springsecurityexample.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
public class IndexController {
@RequestMapping(value = "/", method = RequestMethod.GET)
public String index() {
return "index";
}
@RequestMapping(value = "/admin/index", method = RequestMethod.GET)
public String adminIndex() {
return "adminIndex";
}
}
Kemudian satu jsp sederhana sebagai halaman login,
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
</head>
<body>
<h1>Hello Spring MVC!</h1>
<h2>Tolong Login Dulu </h2>
<c:if test="${not empty param.error}">
<div style="color: red;">
Username atau Password Salah
</div>
</c:if>
<form action="j_spring_security_check" method="POST">
<table>
<tr>
<td>
username
</td>
<td>
<input name="j_username" type="text" />
</td>
</tr>
<tr>
<td>
password
</td>
<td>
<input name="j_password" type="password" />
</td>
</tr>
<tr>
<td colspan="2">
<input name="submit" type="submit" />
</td>
</tr>
</table>
</form>
</body>
</html>
Dan halaman admin sederhana, yang hanya bisa diakses apabila sudah login yang isinya link logout.
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
</head><a href="http://edwin.baculsoft.com/wp-content/uploads/2014/11/springsecurity-login-gagal.png"><img src="http://edwin.baculsoft.com/wp-content/uploads/2014/11/springsecurity-login-gagal.png" alt="springsecurity login gagal" width="458" height="287" class="aligncenter size-full wp-image-1535" /></a>
<body>
<h1>Selamat, anda sudah login -- admin page</h1>
<br />
<a href="${pageContext.request.contextPath}/logout">logout</a>
</body>
</html>
Berikut adalah tampilan struktur netbeans project
Tampilan halaman login, dan tampilan jika login gagal,
Jika login dengan username edw dan password 123456, maka akan tampil halaman seperti berikut,
Source lengkapnya, bisa diakses di github saya, di url ini.
Recently ive met a new exception on my Glassfish 3.1 log file, here is the complete stack trace
[#|2014-10-09T13:22:09.248+0700|INFO|glassfish3.1.2| org.shoal.ha.cache.command.load_request|_ThreadID=301;_ThreadName=Thread-2;| Skipped Loading of 396544c17b8bbbc620000f9b2196 since there is only one instance running in the cluster.|#]
Because of this error, somehow im unable to do a session failover on my Glassfish.
Using asadmin get-health show that my instance are both healthy and alive
glassfish3>asadmin get-health Enter the value for the clusterName operand> cluster1 instance1 started since Thu Oct 09 16:43:21 ICT 2014 instance2 started since Thu Oct 09 16:45:40 ICT 2014 Command get-health executed successfully.
but both instances started not at the same time.
So what i do is very simple, i restarted my cluster so both of my instances started at the same time. And somehow, my error is gone and i can do failover seamlessly.
Today i’ve found a very weird error on my Glassfish 3.1, here is the complete stack trace
[#|2014-10-09T10:54:02.685+0700|SEVERE|glassfish3.1.2|global|_ThreadID=24;_ThreadName=Thread-2; |Class [ java/lang/AutoCloseable ] not found. Error while loading [ class com.edw.dodol.service.MyService ]|#]
Im using SpringMVC and the error affect all my service classes, so somehow my application is unable to start.
After trying several solution, i found out that my JAVA_HOME variable are still pointing to a JDK6 version, while my application need at least JDK7.
Changing my JAVA_HOME variable into JDK7 solve this issue.
A very weird error actually, usually running an application under a different SDK version will create a “Major-Minor Version Exception”, but somehow i cant see that error anywhere 🙁
It is the first time im using Mule ESB, so im trying to create a simple tutorial using it.
In this tutorial, im trying to do a simple GET request. But first, a simple POST request for comparation.
<expression-component doc:name="Expression"> <![CDATA[ sendFields = new java.util.HashMap(); sendFields['aaa']='1'; sendFields['bbb']='2'; payload = sendFields;]]> </expression-component> <http:outbound-endpoint exchange-pattern="request-response" method="POST" address="http://192.168.0.1/" contentType="application/x-www-form-urlencoded" doc:name="HTTP" />
Looks very simple, create a simple hashmap, send it through http outbond using POST method.
While this is my code for GET method
<http:outbound-endpoint exchange-pattern="request-response" method="GET" connector-ref="NoSessionConnector" address="http://192.168.0.1/?aaa=1&bbb=2" contentType="text/html" doc:name="HTTP" />
So instead of pushing my parameters via hashmaps, i add them directly on my url.
