[Rob Morning]

Save it in the session usingsomething like

session.setAttribute("USER",user);
session.setAtttribute("SEX",sex);

in your JSP ..

Is that what you mean ?

[harish pathak]

no i mean like in our jsp we do like this so how we do in struts.

<%
String s =" harish";

%>

<a href="/abc.jsp?name=<%=s%>">click here</a>



How can we pass parameters in struts


Thanks

The equivalent of your example using struts tags would be:

<bean:define id="userName" value="Harish"/>
<a href='/abc.jsp?name=<bean:write name="userName" />'>click here</a>

You can pass it in the similar manner as you pass in jsp.Are you facing any problems with this if so plz let me know

[Thierry Collogne]

If you pass your parameter like this

  
String userName= "test";
pageContext.setAttribute("user", userName);
 
<html:link action="/action" paramName="name" paramId="user" />">click here</a>

You can use the following to retreive

    
String name = request.getParameter("name");

I hope this helps.

Sorry, little mistake

    
String userName= "test";
pageContext.setAttribute("user", userName);
 
<html:link action="/action" paramName="name" paramId="user" />">click here</a>

is wrong. This needs to be

    
String userName= "test";
pageContext.setAttribute("user", userName);
 
<html:link action="/action" paramName="user" paramId="name" />">click here</a>

The paramName is the value, as it is in the pagecontext, you want to pass and paramId is the name of the parameter.

Hi,

Make a FormBean (ActionForm) of the JSP from where you are passintg the value and declare getter/setter of the variable which is holding your value.

For "?name=abc&sex=male" define a form bean which have getter/setter for name and sex variables.

In the action, retrieved the values of name and sex using form's getter method.

E.g:

public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
MyForm myForm = (MyForm)form;
String name=myForm.getName();
System.out.println("name value rertrieved in Action: "+ name);

Hope it will helps.

Bye,
Viki.

Craeting the bean with setters and getters works fine , but if we use this approach only those value can be obtained which are there in form (e.g.text boxes etc).But what should i do if i want to pass some additional parameters thru that JSp page.
I wish to use hidden variables for this but when i try to assign value to a hidden variable then it gives error as bellow
"According to TLD, tag html:hidden must be empty, but is not"

How can i use hidden variables in struts then

Please post your html:hidden code block. Read this first and see if it helps:

I found the solution by my own
you just have to set the object in pagecontext.setattribute(String arg0, Object arg1)
then <html:link action="......" paramid="XXX" paramName="String arg0"/>

you can retrieve this parameter in your action class as :
request.getParameter("XXX"/paramid);


here in code view:


<%String mail=sf.getEmailid();
pageContext.setAttribute("emailid",mail);%>

<html:link action="/information" onfocus="focus()" paramId="mailid" paramName="emailid" scope="request"><font color="#00FF00">

<%= sf.getEmailid() %></font></html:link></td>
<%}%>



here sf.getEmailid() is a String type Object which i have to pass as a parameter from a jsp to action class in link form.
hope you like this , and definetly it will work.
