How to call a Web Service For Cross Domain in FLEX

Step1: 

Set The Paths For the Java and Blazeds.

                 CATALINA_HOME: C:\blazeds-turnkey-4.0.0.14931\tomcat.

             Java Paths: 

                 Java_Home: C:\Program Files\Java\jdk1.7.0_03;

                 path: C:\Program Files\Java\jdk1.7.0_03\bin; 

Step2:

In  C:\blazeds-turnkey-4.0.0.14931\tomcat\Webapps  create a folder with a some name

And then go to samples folder copy WEB_INF folder in that folder and paste that WEB_INF folder in

Folder which you created.

Step3:

 WEB-INF must contain

classes,flex,jsp,lib,src folders and web.xml file.

Step4:

Create A project in  Flash Builder by selecting the Blazeds server with

                Root Folder:       C:\blazeds-turnkey-4.0.0.14931\tomcat\webapps\folder Name   

                Root URL:          http://localhost:8400/Webconfigfile\ folder Name  

                Context Root:    \ folder Name

Step5:

In Flex Application Declaration block

<s:WebService  id="WBSample"
                             destination="ws-catalog"
                             useProxy="true"
                             result="WBSample_resultHandler(event)"
                             fault="WBSample_faultHandler(event)"
 load="WBSample.CelsiusToFahrenheit(12)" />

Step6:

 In the folder which you Created open WEB_INF folder --> flex folder --> proxy-config file with notepad.

                In that set the destination tag like this below

<destination id="ws-catalog" 
 <properties>
<wsdl>http://www.w3schools.com/webservices/tempconvert.asmx?wsdl</wsdl>
 <soap>*</soap>
</properties>
 <adapter ref="soap-proxy"/>
 </destination>

  In that destination id and destination  attribute in Webservice tag should be same.  

                               Without server directly from flex:
 Step1:
In Flex Application Declaration block 

     <s:WebService id="wsSaveEmployee" 
wsdl="http://www.w3schools.com/webservices/tempconvert.asmx?wsdl" 
          showBusyCursor="true">
          <s:operation name="CelsiusToFahrenheit"
                   resultFormat="object"
                   result="saveChangePwdresult(event)" 
fault="saveChangePwdfault(event)"/>
     </s:WebService>

 Step2:

 CelsiusToFahrenheit is the method name in WebService.           

              wsSaveEmployee.CelsiusToFahrenheit.send(24);
