小妹又求助了！jdbc，帮忙看看sql语句是不是写的有问题吧。
代码如下：
Connection con2=(Connection)JDBCConn.getConn("system","cc1517");
//Connection con2=(Connection)JDBCConn.getConn("system","cc1517");

if(con2!=null){
System.out.println("con2 not null");
}
else
System.out.println("con2 null");

Statement st2=(Statement)JDBCConn.getStatement(con2);
String sql2="create tablespace Tyson1_space logging datafile " +
"'F:\\Oracle\\product\\10.1.0\\oradata\\orcl\\Tyson2_data.dbf'" +
" size 20m autoextend on next 20m maxsize unlimited extent " +
"management local;" ;
String sql3="create user Tyson identified by Tyson default " +
"tablespace Tyson1_space;" ;
//+"temporary tablespace softrdcdb_temp;";
try{st2.executeQuery(sql2);}
catch(SQLException e) {
e.printStackTrace();
}
try{st2.executeQuery(sql3);}
catch(SQLException e) {
e.printStackTrace();
}


程序的想法是：用oracle的system管理员身份获得连接，用sql语句生成表空间和创建用户名和密码。觉得是不是sql语句写的有问题呢？
编译后报错如下：

con2 not null
java.sql.SQLException: ORA-00911: 无效字符

  以下省略。。。。



------解决方案--------------------
management local;" 去掉 下面那句也是
