Weblogic 10.3 的JNDI 配置

weblogic10.3 這個(gè)應(yīng)用服務(wù)器是oracle 收購(gòu)Bean 公司后新出的版本．今天試用下，發(fā)現(xiàn)不錯(cuò)．將ＪＮＤＩ的配置過程一一記錄，
1: 啟動(dòng)weblogic 10.3 采用默認(rèn)密碼進(jìn)入
2:在JDBC-DATASOURCE 中假建一個(gè)應(yīng)用數(shù)據(jù)源．
3:在 Configuration-->Connection Pool-->Advanced 中的Test Connections On Reserve 一定要溝上，不然會(huì)測(cè)試通不過
4:填寫測(cè)試的表名 Test Table Name: 等信息

５：編寫測(cè)試的ＪＳＰ文件

<!doctype html public "-//w3c//dtd html 4.0 transitional//en" "http://www.w3.org/TR/REC-html40/strict.dtd">

<%@ page import="java.sql.*"%>

<%@ page import="javax.sql.*"%>

<%@ page import="javax.naming.*"%>

<%@ page session="false"%>

<html>

<head>

</head>

<body>

<%

out.print(" Test Jndi Begin !! ");

DataSource ds = null;

try {

InitialContext ctx = new InitialContext();

ds = (DataSource) ctx.lookup("jdbc/mysql");

Connection conn = ds.getConnection();

Statement stmt = conn.createStatement();

String strSql = " select * from tb_adminuser";

ResultSet rs = stmt.executeQuery(strSql);

while (rs.next()) {

out.println(rs.getString(4));

}

out.print("Test is over");

}catch (Exception ex) {

out.print("ERROR:" + ex.getMessage());

ex.printStackTrace();

}

%>

</body>

</html>

6:編寫　JUNIT

package com.XXXXXX.framework.datasource;

import java.sql.Connection;

import java.sql.ResultSet;

import java.sql.Statement;

import java.util.Hashtable;

import javax.naming.Context;

import javax.naming.InitialContext;

import javax.sql.DataSource;

import junit.framework.TestCase;

public class TestJndi extends TestCase{

public void testJndi() throws Exception{

Hashtable ht = new Hashtable();

ht.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");

ht.put(Context.PROVIDER_URL, "t3://localhost:7001");

Context initial = new InitialContext(ht);

DataSource ds = (DataSource) initial.lookup("jdbc/mysql");

Connection connect = ds.getConnection();

Statement stmt = connect.createStatement();

String strSql = " select * from tb_adminuser";

ResultSet rs = stmt.executeQuery(strSql);

while(rs.next()){

System.out.println(rs.getString(2));

}

其中在編寫JUNIT 的時(shí)候，有一個(gè)插曲．我在網(wǎng)上看到別人的代碼是用t3://localhost:7007

我也照COPY，結(jié)果出現(xiàn)錯(cuò)誤如下:

換成 t3://localhost:7001
測(cè)試成功．看來不懂就到網(wǎng)上亂COPY代碼，還是不行的

我已經(jīng)在配置文件里配置了context.java.naming.factory.initial，而在這里還提示這個(gè)錯(cuò)誤
關(guān)鍵看這里

Error initializing JtaTransactionConfig while looking up UserTransaction (javax.transaction.UserTransaction). Cause: javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial

在jvm里加上一個(gè)參數(shù)，測(cè)試一下

-Djava.naming.factory.initial=weblogic.jndi.WLInitialContextFactory

運(yùn)行通過

這個(gè)參數(shù)在：右鍵項(xiàng)目--Run as --Open Run Dialog--Arguments的VM arguments中添加即可
