get data from servlet to html

[lema]

hallo folk,

here is the thread from where this thread occured get data from html to servlet

the question is, after getting data (username, password) into servlet, and after checking the user's authorizatin in servlet through a server-side-mehtod, can i get an approval data (for example boolean b) back to jsp page. if (b) open application page, else error page..

I dont understand why jsp want to be a controller. See JSP Is Meant For

Only presenting the data. Your Logic Or Controller Part should be

handled by Servlet. Did you get it?

Hei Lema, In Servlet You create the RequestDispathcher Object.

Then Write Simple If Condition. If user exists forward him to exact page

else

error.jsp

..so it means i can't use any data from servlet in jsp, right. then i gotta get back to the old problem - opening applicatin page from servlet in the same browser.

Yes You Can. You Need To put the date in Httpsession, or Cookie

in httpSessin i save the the object User. and i save it after checking the user's authorization.
here is how i log in and send username&password to servlet

<table>
<tr>
<td>Username: </td>
<td align = "left" width="20"><input name="username" type="text" size="40"></input></td>
</tr>
<tr>
<td>Password: </td>
<td align = "left" width="20"><input name="password" type="password" size="40"></input></td>
</tr>
<tr><td>
<input type="submit" name="enter" value="Enter SMD"></input>
</td></tr>
</table>
</form>

the question is, how can i open the application page on same browser after checking the authorization? how? in jsp page through onClick, or in servlet through Dispatcher?

Lema,
If you use dispatcher and not putting the data in session

then what is happening?
