Ajax Implementation of dwr

The memory is too bad. Take a note ,,,

Step 1:

Download the dwr jar package and place it in the lib folder;

Click Open Link

Step 2:

Configure DWR in web. xml;

[Html]
<Servlet>
<Servlet-name> dwr-invoker </servlet-name>
<Servlet-class> uk. ltd. getahead. dwr. DWRServlet </servlet-class>
<Init-param>
<Param-name> debug </param-name>
<Param-value> true </param-value>
</Init-param>
</Servlet>
<Servlet-mapping>
<Servlet-name> dwr-invoker </servlet-name>
<Url-pattern>/dwr/* </url-pattern>
</Servlet-mapping>

<Servlet>
<Servlet-name> dwr-invoker </servlet-name>
<Servlet-class> uk. ltd. getahead. dwr. DWRServlet </servlet-class>
<Init-param>
<Param-name> debug </param-name>
<Param-value> true </param-value>
</Init-param>
</Servlet>
<Servlet-mapping>
<Servlet-name> dwr-invoker </servlet-name>
<Url-pattern>/dwr/* </url-pattern>
</Servlet-mapping> Step 3:

Create the DWR configuration file dwr. xml

[Html]
<Dwr>
<Allow>

<Create creator = "new" javascript = "AjaxBean">
<Param name = "class" value = "com. test. ajax. AjaxBean"/>
</Create> -->

<Create creator = "new" javascript = "AjaxMonitor">
<Param name = "class" value = "com. anthony. struts2.action. MonitorAction"/>
</Create>

<! -- Configure the DWR form validators -->
<Create javascript = "validator" creator = "new">
<Param name = "class"
Value = "org. apache. struts2.validators. DWRValidator"/>
</Create>
<Convert converter = "bean"
Match = "com. opensymphony. xwork2.ValidationAwareSupport"/>
</Allow>
<Signatures>
<! [CDATA [
Import java. util. Map;
Import org. apache. struts2.validators. DWRValidator;

DWRValidator. doPost (String, String, Map <String, String> );
]>
</Signatures>
</Dwr>

<Dwr>
<Allow>

<Create creator = "new" javascript = "AjaxBean">
<Param name = "class" value = "com. test. ajax. AjaxBean"/>
</Create> -->

<Create creator = "new" javascript = "AjaxMonitor">
<Param name = "class" value = "com. anthony. struts2.action. MonitorAction"/>
</Create>

<! -- Configure the DWR form validators -->
<Create javascript = "validator" creator = "new">
<Param name = "class"
Value = "org. apache. struts2.validators. DWRValidator"/>
</Create>
<Convert converter = "bean"
Match = "com. opensymphony. xwork2.ValidationAwareSupport"/>
</Allow>
<Signatures>
<! [CDATA [
Import java. util. Map;
Import org. apache. struts2.validators. DWRValidator;
 
DWRValidator. doPost (String, String, Map <String, String> );
]>
</Signatures>
</Dwr> Step 4:

Access http: // localhost: 8080/PoliceMap02/dwr, that is, add dwr to the end of your project to obtain the following resources:

[Html]
<Script src = "./dwr/engine. js"> </script>
<Script src = "./dwr/util. js"> </script>
<Script src = "./dwr/interface/AjaxMonitor"> </script>

<Script src = "./dwr/engine. js"> </script>
<Script src = "./dwr/util. js"> </script>
<Script src = "./dwr/interface/AjaxMonitor"> </script> place the preceding Resources in the header of the page.

Step 5:

Test:

Page Submission request

[Javascript]
// Set the SMS center number
Function SetPhoneSMS (){
Var key = onlineList. options [onlineList. selectedIndex]. value;
Var num = document. getElementById ('setphonenum'). value;
Window. alert (num );
AjaxMonitor. setPhoneNum (key, num, processSMS );
}

// Set the SMS center number
Function SetPhoneSMS (){
Var key = onlineList. options [onlineList. selectedIndex]. value;
Var num = document. getElementById ('setphonenum'). value;
Window. alert (num );
AjaxMonitor. setPhoneNum (key, num, processSMS );
}
Background processing:

[Java]
<SPAN style = "WHITE-SPACE: pre"> public class MonitorAction {</SPAN>

Public class MonitorAction {[java] view plaincopyprint? Public String setPhoneNum (String key, String num ){

Int type = OrderSet. SMSCENTERNUM;
SendSetSMSCenterNumber centerNumber = new SendSetSMSCenterNumber ();
CenterNumber. setSMSNum (num );
Byte [] bytes = centerNumber. toBytes ();
HandleSend. parseOrder (type, key, bytes );
Return null;
}

Public String setPhoneNum (String key, String num ){

Int type = OrderSet. SMSCENTERNUM;
SendSetSMSCenterNumber centerNumber = new SendSetSMSCenterNumber ();
CenterNumber. setSMSNum (num );
Byte [] bytes = centerNumber. toBytes ();
HandleSend. parseOrder (type, key, bytes );
Return null;
}
