    <p>I am developing A Web Application using <code>JSP</code> &amp; <code>Servlets</code> (Container: <code>Tomcat7</code>, Database: <code>Oracle10</code>)</p> <p>I have developed some web applications like <code>Profile</code>, <code>Reports</code>, <code>Leads</code>. Then I have developed A <code>Login</code> application. In this application I am storing <em>USERID</em> in <code>Session</code> with some more session attributes.</p> <p>After user logs in he will be shown menu which contains links to other Applications like links to <code>Profile</code> Application.</p> <p>So when I access <code>Session</code> after user log in:</p> <ul> <li>If I try to access session withing the same application(Login) then I get session with all the required attributes</li> <li>But when I try to access session from other applications like <code>Profiles</code> then I get session as <code>null</code></li> </ul> <p><strong>code snippet to check session</strong> (Servlet Filter in Login web application)</p> <pre><code>HttpSession session = request.getSession(false); if(session==null) { System.out.println("Session does not exist... Redirected to LOGIN Page."); response.sendRedirect("/ApplicationName/Login.jsp"); } </code></pre> <p>I am accessing session in <code>Profile</code> application to check whether user is logged in or not.</p> <p>Then I have searched, and I have found that <code>Session</code> can't be accessed from other applications for security reasons.(I have also found that it can be done by setting <code>crossContext="true"</code>)</p> <p>Then I have found other option like making <code>EAR</code> of all applications and then deploy it, but unfortunately <code>EAR</code> it is not supported by <code>Tomcat7</code>.</p> <p>I am new to web environment, so if anyone has worked on this before then please let me know what can be the options?</p> <p>Thanks in advance</p> <p><strong>Update1</strong></p> <p>Now I have decided to use <code>EAR</code>, in which I will pack all <code>WAR</code> files and then I will try to share session between them. since Tomcat doesn't support <code>EAR</code> I have installed <code>Oracle Glassfish</code>, Then I have created <code>Enterprise Application Project</code> which contains two Applications <code>1. Login</code> and <code>2. Profiles</code>, and then created <code>EAR</code> file, and deployed it on <code>Glassfish</code>. So I want to share session between those two applications(on Glassfish), so if anybody has any idea about it then please let me know. (link to any tutorial will also be appreciated)</p>

    1. COmeans you want to share data between several application running on same web server. This you can do with some manipulation in web servers Catalina. I don't think there will be another method for doing this,

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
