使用eclipse通过weblogic开发简单的ejb应用（weblogic 10.x & ejb3.x）

1. 创建maven项目: ilucky-ejb-3.0-weblogic, 然后按照如下过程，将其转换为ejb项目:
   

直接看serve端代码:

package com.ilucky.ejb;public interface EJBDemoIntf {    String sayHi();}

package com.ilucky.ejb;import java.util.Random;import javax.ejb.Remote;import javax.ejb.Stateless;@Stateless(mappedName="EJBSessBean")@Remote(EJBDemoIntf.class)public class EJBSessBean implements EJBDemoIntf {    public String sayHi() {        Random r = new Random();        int i = r.nextInt(10);        System.out.println("=============EJB Client comming=================(i % 3）=" + (i % 3));        if(i % 3 == 0) {            int j = 0;            System.out.println("========> zero " + i/j);        }        return "Hello World !!!";    }}

pom.xml文件内容如下:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">  <modelVersion>4.0.0</modelVersion>  <groupId>com.ilucky.ejb</groupId>  <artifactId>ilucky-ejb-3.0-weblogic</artifactId>  <version>0.0.1-SNAPSHOT</version>  <packaging>jar</packaging>  <name>ilucky-ejb-3.0-weblogic</name>  <url>http://maven.apache.org</url>  <properties>    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>            <!-- other plugin versions -->        <version.compiler.plugin>2.3.1</version.compiler.plugin>        <version.ejb.plugin>2.3</version.ejb.plugin>        <!-- maven-compiler-plugin -->        <maven.compiler.target>1.6</maven.compiler.target>        <maven.compiler.source>1.6</maven.compiler.source>  </properties>  <dependencies>      <dependency>            <groupId>javax.ejb</groupId>            <artifactId>javax.ejb-api</artifactId>            <version>3.2</version>        </dependency>         <dependency>            <groupId>com.weblogic</groupId>            <artifactId>weblogic</artifactId>            <version>10.3</version>        </dependency>  </dependencies>  <build>        <!-- <finalName>${artifactId}</finalName> -->        <!-- Set the name of the deployment -->        <plugins>            <!-- Compiler plugin enforces Java 1.6 compatibility and activates annotation                 processors -->            <plugin>                <artifactId>maven-compiler-plugin</artifactId>                <version>${version.compiler.plugin}</version>                <configuration>                    <source>${maven.compiler.source}</source>                    <target>${maven.compiler.target}</target>                </configuration>            </plugin>            <plugin>                <groupId>org.apache.maven.plugins</groupId>                <artifactId>maven-ejb-plugin</artifactId>                <version>${version.ejb.plugin}</version>                <configuration>                    <ejbVersion>3.1</ejbVersion>                    <!-- this is false by default -->                    <generateClient>true</generateClient>                </configuration>            </plugin>        </plugins>    </build></project>

注意: 最后需要将其打包安装到本地仓库，因为下面的client项目会依赖它。
即 mvn clean install

1. 创建maven项目: ilucky-ejb-3.0-weblogic-client，client代码如下：

package com.ilucky.ejb;import javax.naming.InitialContext;public class EJBDemoTest {    private static String ip="10.0.2.90";    private static String port = "7001";//  /**//   * 获取配置//   *///  public static void initConf() {//      //  }    public static void main(String[] args) {        java.util.Properties prop = new java.util.Properties();          prop.setProperty(javax.naming.Context.INITIAL_CONTEXT_FACTORY,  "weblogic.jndi.WLInitialContextFactory");        prop.setProperty(javax.naming.Context.PROVIDER_URL, "t3://"+ip+":" + port);        InitialContext ic;        try {            ic = new InitialContext(prop);            EJBDemoIntf h = (EJBDemoIntf)ic.lookup("EJBSessBean#com.ilucky.ejb.EJBDemoIntf");              String result = h.sayHi();            System.out.println("=======ejb return result=======>"+result);        } catch (Exception e) {            e.printStackTrace();            System.out.println("=====================");        }      }}

pom.xml文件内容如下:

需要注意的有两点:
1. 如下是对server的依赖。

<dependency>             <groupId>com.ilucky.ejb</groupId>            <artifactId>ilucky-ejb-3.0-weblogic</artifactId>            <version>0.0.1-SNAPSHOT</version>            <exclusions>                <exclusion>                    <groupId>com.weblogic</groupId>                    <artifactId>weblogic</artifactId>                </exclusion>            </exclusions>        </dependency> 

1. 如下的文件需要自己生成。

    <dependency>            <groupId>com.wlfullclient</groupId>            <artifactId>wlfullclient</artifactId>            <version>10.3</version>        </dependency>

client要导入wlfullclient.jar, 但是你会发现weblogic里面没有带wlfullclient.jar, 需要自己生成:
1 cd C:/${weblogic_home}/wlserver_10.0/server/lib
2 java -jar ../../../modules/com.bea.core.jarbuilder_1.0.7.0.jar(若weblgic版本不同则jarbuilder.jar的版本略有差异略有差异,到../../../modules目录下看一看就知道了)
