how to understad a form is submitted in struts actions - struts2

Question

In struts2 actions the injection is used for setting the property values of an action class, so the properties are updated by form fields on the form submission. To discover which form is submitted I create a method calling isFormSubmitted() and in there I check a redundant property created only for this motive. The property is updated in a hidden field. But I find this workout so dirty! I think that there must be a better way to solve this problem.
What I do is:
<s:form name="form1">
<s:hidden name="submit" value="10" />
...other fields go here
</s:form>
in the action class I have getSubmit, setSubmit methods and the following method:
public boolean isFormSubmitted(){
return (submit == 10);
}

Your can call different action methods in your action, not only "execute" method. Just put the parameter with the name like "method:actionMethodName" in your request. Here is example:
public class MyAction extends ActionSupport {
public String execute() {
// Base code
return SUCCESS;
}
public String one() {
// Code one
return SUCCESS;
}
public String two() {
// Code two
return SUCCESS;
}
}
And here is jsp:
<s:form action="MyAction">
<input type="submit" value="Call execute"/>
<input type="submit" name="method:one" value="Call method one"/>
<input type="submit" name="method:two" value="Call method two"/>
</s:>
Or you can do it like this:
<s:form action="MyAction" name="form0">
<!-- call execute-->
</s:>
<s:form action="MyAction" name="form1">
<!-- call method one-->
<input type="hidden" name="method:one"/>
</s:>
<s:form action="MyAction" name="form2">
<!-- call method two-->
<input type="hidden" name="method:two"/>
</s:>

You should use <s:form> tag action attribute to submit to specific action.
<s:form action="action1">
...
</s:form>
<s:form action="action2">
...
</s:form>
See the <s:form> tag documentation: http://struts.apache.org/2.x/docs/form.html.
Update
Then just use separate actions for loading and saving the user.

Answer 3

you should do the submission of the form something like this.
<s:form name="form1">
<s:hidden name="submit" value="10" />
</s:form>
create a java script function
function onclick()
{
document.form1.submit();
}
then create getters & setters in action for hidden field
and in execute method
public String execute()
{
setSubmit(10);
return SUCCESS;
}
Update :
or
<s:a href="your_action"></a>
