Connection reset by peer: JVM_recv in socket input stream read

[zhanghm]

访问oracle数据库时，为什么会出现这样的错误：
java.sql.SQLException: Io 异常: Connection reset by peer: JVM_recv in socket input stream read
以及
Exception in: R( + /Jsp1.jsp + null) - javax.servlet.ServletException
at org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:459)
...

请各位大虾帮忙

把最后的SQL贴出来

myDriver = (Driver)Class.forName(driverName).newInstance();
dbConn = this.getConnection();

运行dbConn = this.getConnection();时出错
