Import Web Service(WSDL) Wizard in Flex 3.0

Using webService In Flex 3.0 Application

Flex  3.0  provides  the  easiest  way  to  use  the  web  services. Under the ‘Data’  Menu on your  Flex Builder IDE there is a submenu namely ‘Import Web Service(WSDL)’,We can use it to Directly use the Web Services.Just create a Flex  Project. No need  to chose any  ’Applciation Server Type’  under ‘Server Technology’  title. After that just go to the Import Web Service(WSDL)’ under ‘ Data’ menu.

After clicking on this you will see like below.

Just click on the ‘Next’ button.

Now you have to enter your webService url in the box with label ‘WSDL URI‘,and after that just click on the ‘Next’ button. 

Here you can  change  the  service  if  you are  having  more than  one  service. Also  you  can  change package.If you  don’t  want  just  click  on ‘Finish‘.  After  you  will  click  on  the  ‘Finsh’ button you will find  a folder ‘generated’  under  your  ’src’ folder in  your  application. Under this ‘generated’ folder there  you will saw a ‘webservice’ folder. Just  open  it  and  find  the total conversion  of  your webservice in now action Script 3. Just  open  the ‘Service.as’ file you  will  find  how to use these classess for retreving results from your WebService. I  am  just  telling you the way of using it via MXML tags,you can also use these with action script. Just  copy  and  paste  the  code below in  you Application file,and run it to find out the result.
