Re: How to use doPost method in Formpanel submit button. How to map that servlet in web.xml.

 

i got an idea about how to use GWT Form Panel in Eclipse...

At Same time,

My Class Name is: User.Java

inside of "/src/sample/model/"

My servlet name is  : AddUserSerivesImpl

inside of "/src/sample/server/"

My Main Class Name is  : Sample.java

inside of "/src/sample/client/" 

from Sample.java class i am using Form Panel. 

which url i want to submit button Action.

FormPanel form=new FormPanel();

form.setAction="  ?         ";

method is doPost.

while, 

how to map that  servlet inside the web.xml

<servlet>

<servlet-name>AddNewUser</servet-name>

<servlet-class>sample.server.AddUserServiceImpl</servlet-class>

</servlet>

<servlet-mapping>

<servlet-name>AddNewUser</servet-name>

<url-pattern> ? </url-pattern>

</servlet-mapping> 

 

My Question is..

1) In that question mark symbol place i want to give same address?

2) inside the url address, which url address i want to give for map that servlet?

3) Inside the setAction, which url i want to give the call the servlet ( AddUserServiceImpl.java). ?

i tried this way..

1st Way....

inside the  setAction... form.setAction("AddNewUser");

inside the url in web.xml.......<url-pattern>/AddNewUser</url-pattern>

2nd Way...

inside the  setAction... form.setAction("/AddNewUser");

inside the url in web.xml.......<url-pattern>/AddNewUser</url-pattern>

3rd Way..

inside the  setAction... form.setAction("/AddNewUser");

inside the url in web.xml.......<url-pattern>/sample/server/AddNewUser</url-pattern>

4th Way..

inside the  setAction... form.setAction("AddNewUserServiceImpl");

inside the url in web.xml.......<url-pattern> /sample/server/AddNewUser </url-pattern>

those 4's way i didn't add the value to the database. i have doubt first that action and servlet url is correct or not?
