Hi depak,

in struts-config.xml file u can specify the multile link for a single page throug action tag. that multiple links can be accessed in action servlet.
For Example:
in struts-config.xml :

<action path="url"  type="actionClass" name="formBeanName">
<forward property="sucess" path="default url"/>
<forward name="likn1" path="link1 url.do"/>
<forward name="likn2" path="link2 url.do"/>
</action>

hi Yuvraj,

Thank u vry much for the reply, but still i didn't get the point :(

i have two buttons BUTTON A, BUTTON B on a single page. In struts config file how can i associate two different actions for a single page. In my case how will i associate different actions with BUTTON A and BUTTON B ?

For this do i need to do any change in java file (Action Class)? If yes then what type of changes? And if i need to do some other changes then please let me know.

Please bear with me for my silly questions.

Regards,
Deepak

Hi Deepak,

1) While clicking the buttons u can get the indication in action file sepearatle for button A & B by request parameter or Hidden variables
2) In Action class, u hav to mention the mapping like "return mapping.findForward("link1");" and "return mapping.findForward("link2");"
3) This link1 & link2 are mentioned already in name attribute of struts-config.xml
4) Based on this link name, Page wil be forward to the mentioned url in attribute path of action tag in struts-config.xml

for Examples : refer this site http://www.roseindia.net/struts/

The above site is worst possible place to learn from. Recommending use of old fashion methods and approaches, collecting out of date tutorials with code examples and lastly badly organized.

what'd you expect from an Indian site by homework kiddos for homework kiddos?

I usually recommend them to homework kiddos, provides a good laugh to see them trashing about ;)

you can try with database .
please try to this code if any confusing then ask me .

String login=request.getParameter();
String pass=request.getParameter();
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con=DriverManager.getConnection();
PreparedStatement ps=con.PrepareStatement("select * from ravindra where login=?, password=?");

ps.setString(1,login);
ps.setString(1,pass);
ResultSet rs=ps.executeQuery();
if (rs.next())
{

//enter into the if statement  if login & pass is present in database.

}
else
{
otherwise this.
}
