整合JBoss 3.x 和MS SQL Server 2000

准备工作

安装JBoss 3.x和MS SQL Server 2000 下载Microsoft SQL Server 2000 Driver for JDBC
（http://www.microsoft.com/downloads/details.aspx?familyid=07287b11-0502-461a-b138-2aa54bfdc03a&displaylang=en#filelist） 安装MS SQL Server 2000的sp3补丁包（ http://www.microsoft.com/downloads/details.aspx?FamilyId=90DCD52C-0488-4E46-AFBF-ACACE5369FA3&displaylang=zh-cn#filelist ）。注意，不升级的话是无法正确连接到MS SQL Server 2000上的，会出现Error establishing socket错误。

 

开始整合

 

1.         安装好Microsoft SQL Server 2000 Driver for JDBC后，在其安装目录\lib 下有三个包：msbase.jar、mssqlserver.jar、msutil.jar。把他们拷贝到%JBoss安装目录%\server\default\lib下

2.         将Jboss目录下的docs\examples\jca\中的mssql-ds.xml和mssql-xa-ds.xml拷贝到\server\default\deploy\目录下，并做相应修改(红色部分)：

mssql-ds.xml：

<datasources>

   <local-tx-datasource>

       <jndi-name>MSSQLDS</jndi-name>      
       <connection-url>jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=Northwind</connection-url>

       <driver-class>com.microsoft.jdbc.sqlserver.SQLServerDriver</driver-class>

       <user-name>sa</user-name>

       <password></password>

   </local-tx-datasource>

</datasources>

 

mssql-xa-ds.xml:

<datasources>

   <xa-datasource>

       <jndi-name>MSSQLXADS</jndi-name>

       <xa-datasource-class>com.microsoft.jdbcx.sqlserver.SQLServerDataSource</xa-datasource-class>

       <xa-datasource-property name="ServerName">localhost</xa-datasource-property>

       <xa-datasource-property name="DatabaseName">Northwind</xa-datasource-property>

       <xa-datasource-property name="SelectMethod">cursor</xa-datasource-property>

       <!-- not sure if these should be here-->

       <user-name>sa</user-name>

       <password/>

   </xa-datasource>

</datasources>

整合测试

1.         编写SessionBean，在其中添加如下方法：

public String testDS() {

        String resl = null;

        try {

            Properties p = new Properties();

            p.put(Context.INITIAL_CONTEXT_FACTORY,  "org.jnp.interfaces.NamingContextFactory");

            p.put(Context.PROVIDER_URL, "jnp://localhost:1099");

            Context ctx = new InitialContext(p);

 

            resl += "testing the database...\n";

            javax.sql.DataSource ds = (javax.sql.DataSource) ctx.lookup("java:/MSSQLDS");     
             //这个”MSSQLDS”必须和mssql-ds.xml文件中的jndi-name保持一致，否则会出错

            java.sql.Connection conn =null;

            java.sql.Statement st=null;

            java.sql.ResultSet rs=null;

            try {

                conn = ds.getConnection();

                st = conn.createStatement();

                String sqlStr = "select * from Employees";

                rs = st.executeQuery(sqlStr);

                while (rs.next()) {

                    resl += rs.getString("FirstName") + " " +rs.getString("LastName")+"\n";

                }

            } catch (Exception e) {

            }

            finally {

                    if(rs!=null) rs.close();

                    if(st!=null) st.close();

                    if(conn!=null) conn.close();

            }

        } catch (Exception e) {

            e.printStackTrace();

        }

        return resl;

    }

2.         部署EJB

3.         测试SessionBean

public class test{

       public void run() {

        Properties p = new Properties();

        p.put(Context.INITIAL_CONTEXT_FACTORY,  "org.jnp.interfaces.NamingContextFactory");

        p.put(Context.PROVIDER_URL, "jnp://localhost:1099");

        try {

            Context ctx = new InitialContext(p);

            Object obj = ctx.lookup("testBean");

            testHome home = (testHome) PortableRemoteObject.narrow(obj, testHome.class);

            test t = home.create();

 

            System.out.println("test...");

            String str = t.testDS();

            System.out.println("received: \n" + str);

            System.out.println("test finished!\n");

        } catch (Exception e) {

            e.printStackTrace();

        }

    }

 

    public static void main(String[] args) {

        new test().run();

    }

}
