数据类型转换问题
报错的地方

Java code

java.lang.NumberFormatException: For input string: "on"    at java.lang.NumberFormatException.forInputString(Unknown Source)    at java.lang.Integer.parseInt(Unknown Source)    at java.lang.Integer.parseInt(Unknown Source)    at com.bellsent.servlet.EditManagementServlet.doPost(EditManagementServlet.java:66)    at javax.servlet.http.HttpServlet.service(HttpServlet.java:710)    at javax.servlet.http.HttpServlet.service(HttpServlet.java:803)    at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290)    at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206)    at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:230)    at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:175)    at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:128)    at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:104)    at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109)    at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:261)    at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:844)    at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:581)    at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447)    at java.lang.Thread.run(Unknown Source)

我的代码：

Java code

String dType = request.getParameter("dType");        String dIpAdd = request.getParameter("dIpAdd");            int dPort = Integer.parseInt(request.getParameter("dPort"));                        String dDescription = request.getParameter("dDescription");        String dUsrName = request.getParameter("dUsrName");        String dUsrPwd = request.getParameter("dUsrPwd");        int videoChannels = Integer.parseInt(request.getParameter("videoChannels"));                String vch1 = request.getParameter("vch1");        String vch2 = request.getParameter("vch2");

这个错误貌似是说数据转换问题，或者是其他问题，纠结了好长时间，也baidu了好长时间，不知道怎么解决？求帮助~~~

[解决办法]
Integer.parseInt之前先打印一下变量不就知道了
[解决办法]

错误在你的 EditManagementServlet.java:66行 ，数据类型错误，java.lang.NumberFormatException: For input string: "on" 你贴的代码里没有66行
[解决办法]
是不是String类型转成int型的转错了啊
换种方式转试试 

Integer intObj = new Integer(user.getWorkendtime());
int inte = intObj.intValue();

[解决办法]
java.lang.NumberFormatException: For input string: "on"
at java.lang.NumberFormatException.forInputString(Unknown Source)
at java.lang.Integer.parseInt(Unknown Source)

at com.bellsent.servlet.EditManagementServlet.doPost(EditManagementServlet.java:66)


int dPort = Integer.parseInt(request.getParameter("dPort")); 

request.getParameter("dPort") 这个值应该为 "on"了，不能转换

有66行代码的，就是那个Java code

int videoChannels = Integer.parseInt(request.……
