wsad5.0连接as/400的db2数据库出错，请各位高手帮忙，急！
我在window server2000下安装wsad5.0,配置数据源，（as/400是局域网中的另一台机器）1、选的是：DB2 UDB for iSeries (Toolbox XA)
实现类名：com.ibm.as400.access.AS400JDBCXADataSource
用的驱动是jt400.jar
配置好数据源后连接报错：
61e4f531 FreePool E J2CA0046E: 为资源 jdbc/ds1 创建 ManagedConnection 期间，方法 createManagedConnctionWithMCWrapper 捕捉到异常，并抛出 ResourceAllocationException。原始异常：com.ibm.ws.exception.WsException: DSRA8100E: Unable to get a XAConnection from the DataSource.

请各位大侠帮忙解决，我已经郁闷1天啦！ 我2004年刚做完一个中央国债登记结算公司的一个全国性交易的项目，我任项目经理。后台AS400，前置机RS600(Websphere 5.0)，前端Java+explorer。有个team专门负责Websphere开发，包括Websphere开发环境的设置。因为是个人信息保密问题，我不能把他们的电话告诉你。我可以让他门在方便的时候，到这个论坛来解答你的问题，或者你可以直接打电话给IBM技术支持中心。打电话给IBM，是解决问题最佳途径。 谢谢，我现在做的是深圳社保局的项目，也是做项目经理，但是下面的人都不懂这个技术，所以问题就有我来解决啦！我的电话是13424313241，邮箱是makekeok@163.com datasource的配置是什么? TOOLBOX是不需要用户名和密码的 我以前测试写的一段代码，是可以连接上的，我也用WSAD5.0, AS400是V5R3. 当时好像是同时连接sql server和db2.
核心代码如下：
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class DbInput
{
Connection src=null;
Connection dest=null;
Connection connformax=null;
ConnPara srcPara;
ConnPara destPara;
public DbInput(){}
public void dbInit()
{
DbXmlParser xmlparser=new DbXmlParser("dbs.xml");
srcPara=xmlparser.getSource();
destPara=xmlparser.getDest();
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver" );
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
Class.forName("com.ibm.as400.access.AS400JDBCDriver");//2004-8-28 DB2/AS400
src = DriverManager.getConnection( srcPara.getUrl(), srcPara.getUsername(),srcPara.getPassword());
dest =DriverManager.getConnection( destPara.getUrl(), destPara.getUsername(),destPara.getPassword());
connformax= DriverManager.getConnection( destPara.getUrl(), destPara.getUsername(),destPara.getPassword());
}
//捕获加载驱动程序异常
catch ( ClassNotFoundException cnfex ) {
System.err.println( "装载 JDBC/ODBC 驱动程序失败。" );
cnfex.printStackTrace();
System.exit( 1 );// terminate program
} catch ( SQLException ex )
{
System.err.println( "连接失败" );
ex.printStackTrace();
System.exit( 1 );// terminate program
}
}
}
我的XML文件配置如下：
<?xml version="1.0" encoding="GBK"?>
<dbcopy>
<source>
<class>com.microsoft.jdbc.sqlserver.SQLServerDriver</class>
<url>jdbc:microsoft:sqlserver://SqlServerName:port;DatabaseName=dataname;SelectMethod=cursor</url>
<user>username</user>
<password>password</password>
</source>
<dest>
<class>com.ibm.as400.access.AS400JDBCConnectionPoolDataSource</class>
<url>jdbc:as400://as400name;naming=system</url>
<user>User name</user>
<password>password</password>
</dest>
</dbcopy> 大肥肥，你应该做一个连接工厂来做这个好像比较好。
在C#中可以用静态构造函数来获取配置文件的信息
然后用一个静态的方法返回连接~~，这样代码的重用性会高很多~~ wildfish, 很感谢你的指点，谢谢！
说到连接数据库，其实我的这种连接方法在J2EE中不推荐使用，我的这种DriverMarager方法的主要问题是：
它是一个同步的类，这意味着在一个给定的时间内，只有一个线程可以运行，应该尽量使用多线程的DataSource技术。至于DataSource技术，不同的服务器，比如BEA WEBLOGIC,和IBM WEBSPHERE配置有点不同，但是基本都是通过控制台配置，然后绑定到JDNI树上，供应用使用，详细可以查询具体的手册。
我上面给的只是当时写这测试用的代码，见笑。
很高兴能和你探讨，有机会多交流~~ ~~,我对java的代码只是能看得程度，基本上不会写，我从事的是.net的开发。只是我们比较追求代码的重用。架构上的重用。
