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"

                </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

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:

                </executions>
            </plugin>
        </plugins>
    </build>
</project>

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>

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)
