Jan 28, 2014In our J2EE web application we have so many critical functionality which is handled by various component. Say if one of the critical object or the respective critical system is down. How we can serve the request and still get the response from those systems? How this can be handled technically through code? I know we can go for service virtualization and create a system which will emulate the behavior of critical object or system. But for that we need to use the respective tools which is quite costly. How the same can be handled using java code , whether we can create a clone of that critical object and still serve the request even though the original critical object is down or can we create a proxy of that critical object? How we can handle it in java through code?

View Replies View RelatedJSP :: Would Template Based Framework Generates A Lot Of Request Traffic?
Nov 29, 2014If I have a web page with a lot of data to show, say a lot of tables and graphics, would using non JSP based frameworks result in a lot more individual AJAX requests? For example if the page have 5 tables, with JSP the whole page will be returned to the browser with data for all 5 tables already. But if this is a pure HTML / Javascript based view, then we need to have each of the 5 tables to make individual AJAX requests in order to render the page. Is this indeed the down side for not using JSP?
The reason I'm asking is because I'm considering moving away from JSP to a template based framework such as Thymeleaf or Freemarker.

May 20, 2014I am trying to use iText to create a PDF document. I found a nice tutorial online but one thing stumps me. How do I get the URL of the JSP page that contains the content?

Servlets :: Possible To Use Annotations?
Aug 10, 2014Is it permitted or possible to use annotations on classic servlets?
E.g.:
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
[Code] ....
I tried to visit my webapp with /appinfo appended after the context url but I get a 404 and I see no errors in the GlassFish4 log.
My project is using JSF 2.x with the viewservlet mapped on *.xhtml and it is using Spring Beans as well (using the Spring Context Loader), mapped to /rest/*. Do I need to map something else?
I can only get this servlet working without annotations but only using the old web.xml way.
I don't know what I need to do to get my servlet working with annotations.
Servlets :: Not Mapping To URL
Feb 4, 2015I have a servlet that is not mapping to my URL:

<url-pattern>/View/*</url-pattern>

<a href="/View/viewFlow?V1">V1</a>
The resulting link is [URL].... It's bypassing the project name. The link should be [URL]...
Servlets :: How To Map Website URL
Nov 25, 2014I have my mapping as below
<servlet>
<servlet-name>main</servlet-name>
<servlet-class>co.edureka.controllers.MainController</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>main</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
So that I can map the first request coming say www.xyz.net to my first page , it does the work but some of my css and images is not getting displayed .
So I did as below
<servlet>
<servlet-name>main</servlet-name>
<servlet-class>co.edureka.controllers.MainController</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>main</servlet-name>
<url-pattern>/first</url-pattern>
</servlet-mapping>
By doing this my css and images get displayed and everything works fine.
But the problem is I want to display my first page as user puts the url.
I am putting my jsp pages in WEB-INF/jsps , I am not putting it directly under WEB-CONTENT directory.

Apr 16, 2014I'm trying to go back to basic and strengthen some of my foundation. I'm wondering what kind of data would be appropriate to be stored inside a session?

The web app interacts strictly with employees, so no public facing app (yes, that's right, no shopping cart). So, in this kind of web app, what kind of data that by storing it to session.
View Replies View RelatedServlets :: Calling JSP Page

How do we have the jsp page displayed even when the servlet is executing.
View Replies View RelatedServlets :: Redirect After Login
Jan 30, 2014I have a secured Struts application in WebSphere that uses FORM j_security_check for authentication.There is also a Post Logon "filter" defined which runs some code after a login is processed.The extract from web.xml showing the login configuration and filter is as follows:
<login-config>
<auth-method>FORM</auth-method>
<realm-name>MyRealm</realm-name>
<form-login-config>
<form-login-page>/login.html</form-login-page>
<form-error-page>/error.html</form-error-page>
[code]....
If a user isn't logged into the application and they try to access one of the secured servlets, for example quotes.do, they are directed to the login page to enter their information.If they login successfully, they are then directed to quotes.do, rather than the default "welcome" page. Is there a setting in the web.xml or the post logon filter where I can force j_security_check to ALWAYS go to the default welcome page after a successful login?
