jsp如何读取从sql数据库中用分号“；”隔开的值？

加个函数
<%!public static final String replace(String strSource, String strFrom, String strTo)
{
if(strFrom == null || strFrom.equals(""))
return strSource;
String strDest = "";
int intFromLen = strFrom.length();
int intPos;

while((intPos = strSource.indexOf(strFrom)) != -1)
{
strDest = strDest + strSource.substring(0,intPos);
strDest = strDest + strTo;
strSource = strSource.substring(intPos + intFromLen);
}
strDest = strDest + strSource;

return strDest;
}
%>

var arr=playname.split(";")
这个语句执行以后，数组arr里面包括这些分开的内容，比如arr[0]="1.rm", arr[1]="2.rm"; ...
