想在jbuilder9下配置tomcat连接池，应该怎么做呢？

Question

趁休息时间给你详细说一下吧：
一、在tools - > config servers 中 配置Tomcat :
Home directory 为： D:/JBuilder9/thirdparty/jakarta-tomcat-4.1.24-LE-jdk14
main classes 为：org.apache.catalina.startup.Bootstrap二、在projects - > project properties中 的server 中选择 tomcat三、以MSSQL为例：
在server.xml中加：
        <Context path="" docBase="www"
        debug="5" reloadable="true" crossContext="true">

  <Logger className="org.apache.catalina.logger.FileLogger"
     prefix="localhost_www_log." suffix=".txt"
     timestamp="true"/>

  <Resource name="jdbc/MSSQL7.0DB"
       auth="Container" 
       type="javax.sql.DataSource"/>

  <ResourceParams name="jdbc/MSSQL7.0DB">
    <parameter>
      <name>factory</name>
      <value>org.apache.commons.dbcp.BasicDataSourceFactory</value>
    </parameter>
    <parameter>
      <name>maxActive</name>
      <value>20</value>
    </parameter>
    <parameter>
      <name>maxIdle</name>
      <value>300000</value>
    </parameter>
    <parameter>
      <name>maxWait</name>
      <value>1000</value>
    </parameter>
    <parameter>
     <name>username</name>
     <value>sa</value>
    </parameter>
    <parameter>
     <name>password</name>
     <value>981050</value>
    </parameter>

    <parameter>
       <name>driverClassName</name>
       <value>com.jnetdirect.jsql.JSQLDriver</value>
    </parameter>

    <parameter>
      <name>url</name>
      <value>jdbc:JSQLConnect://172.16.10.99:1433/database=takam</value>
    </parameter>
    <parameter>
      <name>removeAbandoned</name>
      <value>true</value>
    </parameter>
    <parameter>
      <name>removeAbandonedTimeout</name>
      <value>60</value>
   </parameter>
   <parameter>
     <name>logAbandoned</name>
     <value>true</value>
           </parameter>
  </ResourceParams>
</Context>四、
用如下方法进行调用：
 Connection con =null;
    Statement  stmt=null;
    ResultSet  rs  =null;
javax.sql.DataSource ds = (javax.sql.DataSource)new javax.naming.InitialContext().lookup("java:comp/env/jdbc/MSSQL7.0DB");
        if (ds != null)    con = ds.getConnection();
        if (con != null)   stmt=con.createStatement(                ResultSet.TYPE_SCROLL_SENSITIVE,     ResultSet.CONCUR_READ_ONLY
               );String sql="select * from customer";
try{
  rs=stmt.executeQuery(sql);
}catch(Exception ex){
  ex.PrintStackTrace();
}

我配置完运行时报了一大串错：

这是什么问题啊？？？

Answer 2

我本来以为是这些包没加入，我从tools-->configue libraries-->class中引入了这些包，可是还是不行，一样的错误。到底缺少文件跟组件是个什么错误呢？难道是配错了？

Answer 3

对了，后面还有很多
