<p class="MsoNormal"><span style="color:#1F497D">I think the problem is with OpenCMS. Does OpenCMS provide any session management?</span></p>

<p class="MsoNormal"><span style="color:#1F497D">Hi Sankar,</span></p>
<p class="MsoNormal"><span style="color:#1F497D"> </span></p>
<p class="MsoNormal"><span style="color:#1F497D">You do realize you’re trying to modify a final object in your illustration code..?</span></p>
<p class="MsoNormal"><span style="color:#1F497D">final CmsRequestContext requestContext = cmsObject.getRequestContext();</span></p>
<p class="MsoNormal"><span style="color:#1F497D">requestContext.setAttribute("someObj ", someObj);</span></p>
<p class="MsoNormal"><span style="color:#1F497D"> </span></p>
<p class="MsoNormal"><span style="color:#1F497D">Anyway -- my preferred recipe goes like this:</span></p>
<p class="MsoNormal"><span style="color:#1F497D">// Fetch the session object (don’t use the implicitly available variable “session”)</span></p>
<p class="MsoNormal"><span style="color:#1F497D">HttpSession sess = request.getSession(true); // You may or may not want to pass the boolean here</span></p>
<p class="MsoNormal"><span style="color:#1F497D">// Then do like this:</span></p>
<p class="MsoNormal"><span style="color:#1F497D">sess.setAttribute(...);</span></p>
<p class="MsoNormal"><span style="color:#1F497D">sess.getAttribute(...);</span></p>
<p class="MsoNormal"><span style="color:#1F497D"> </span></p>
<p class="MsoNormal"><span style="color:#1F497D">Not forgetting to put session="true" in the @page directive:</span></p>
<p class="MsoNormal"><span style="color:#1F497D"><%@page import=”...” session=”true” %></span></p>
<p class="MsoNormal"><span style="color:#1F497D"> </span></p>
<p class="MsoNormal"><span style="color:#1F497D">You should also be able to use request.setAttribute(...) and request.getAttribute(...) -- just like that, using the implicitly available variable “request”. (The stored object will of course live only for as
long as the request lives.)</span></p>
<p class="MsoNormal"><span style="color:#1F497D"> </span></p>
<p class="MsoNormal"><span style="color:#1F497D">NOTE: If you’re using flex cache, be aware. It doesn’t always play nice with this. It’s supposed to work (if configured correctly) with the session approach, but I’ve had to disable flex cache for some of my
JSPs where I do stuff like this.</span></p>
<p class="MsoNormal"><span style="color:#1F497D"> </span></p>
<p class="MsoNormal"><span style="color:#1F497D">HTH :)</span></p>
<p class="MsoNormal"><span style="color:#1F497D"> </span></p>
<p class="MsoNormal"><span style="color:#1F497D">Cheers,</span></p>

<p class="MsoNormal">Hi,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I am working on OpenCMS application. I am new to OpenCMS.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I have one object which I want to keep it in session so that I can use it in other JSPs.</p>
<p class="MsoNormal">I tried in 2 ways to get this.</p>
<p class="MsoListParagraph" style="text-indent:-.25in">a)<span style="font-size:7.0pt; font-family:"Times New Roman","serif"">
</span>Initially I used JSP implicit variable i.e session.setAttribute(“someObj”,someObj). But this session object is not available in other JSPs. I am getting null when I try to retrieve using session.getAttribute(“someObj”);</p>
<p class="MsoListParagraph" style="text-indent:-.25in">b)<span style="font-size:7.0pt; font-family:"Times New Roman","serif"">
</span>Then I used another approach.</p>
<p class="MsoListParagraph">CmsJspActionElement cms = new CmsJspActionElement(pageContext, request, response);</p>
<p class="MsoListParagraph">final CmsObject cmsObject = cms.getCmsObject();</p>
<p class="MsoListParagraph">final CmsRequestContext requestContext = cmsObject.getRequestContext();</p>
<p class="MsoListParagraph">requestContext.setAttribute("someObj ", someObj);</p>
<p class="MsoListParagraph"> </p>
<p class="MsoListParagraph">I am not sure whether it is in request scope or session scope. When I tried to access it in another JSP, getting null value.</p>
<p class="MsoListParagraph"> </p>
<p class="MsoListParagraph">CmsJspActionElement cms=new CmsJspActionElement(pageContext, request, response);</p>
<p class="MsoListParagraph">final CmsObject cmsObject = cms.getCmsObject();</p>
<p class="MsoListParagraph">final CmsRequestContext requestContext = cmsObject.getRequestContext();</p>
<p class="MsoListParagraph">Object obj = requestContext.getAttribute("someObj ");</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Could you please let me know how to resolve this.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Your help is highly appreciated.</p>
