[opencms-dev] Flex Session variable

[Alexander Kandzior]

Anil,
 
I still do not fully understand what you are trying to do. Can you
please also include the code of the XMLTemplates with the ElementDefs? 
 
I do not see in what context your JSPTemplate class gets called. Since
it extends CmsXmlTemplate is (obviously) seems to be called from a
XMLTemplate. So you would have a XMLTemplate that includes a JSP
element, a function that is not included in the current Flex alpha 1
release. Is it that what you are trying to do?
 
Regards,
Alex.

Alex,
 
What I am trying to do is bit of Hack, I am trying to do Templating with
JSP that you have provided. 
 
public class JSPTemplate extends CmsXmlTemplate

{

static final String JSP_TEMPLATE = "/flexdemo/default.jsp";

static final String PARAMETER_FILE_NAME = "TEMPLATEFILE";




public byte[] getContent(CmsObject cms,String templateFile,String
elementName,Hashtable theParameters,String templateSelector) 



throws CmsException

{

String jspTemplateFileName = (String) theParameters.get(elementName +
"." + PARAMETER_FILE_NAME);

if (jspTemplateFileName == null || "".equals(jspTemplateFileName))

{

jspTemplateFileName = JSP_TEMPLATE;

}

try

{

OpenCms oCms = OpenCms.getInstance();

CmsFile file = oCms.getCmsFile(cms, jspTemplateFileName);

if (file != null)

{

CmsXmlTemplateFile templateDocument =

getOwnTemplateFile(cms, templateFile, elementName, theParameters,
templateSelector);

Enumeration eD =
templateDocument.getAllSubElementDefinitions().elements();

while (eD.hasMoreElements())

{

String eName = (String) eD.nextElement();

String s = templateDocument.getParameter(eName, PARAMETER_FILE_NAME);

HttpServletRequest req = (HttpServletRequest)
cms.getRequestContext().getRequest().getOriginalRequest();



CmsFile tempFile = oCms.getCmsFile(cms, s);



int launcherId = tempFile.getLauncherType();

String startTemplateClass = file.getLauncherClassname();

I_CmsLauncher launcher =
cms.getLauncherManager().getLauncher(launcherId);

CmsJspLoader j = (CmsJspLoader)launcher ;

String jspName = j.getJspUri(s, false);

req.setAttribute(eName, jspName);

HttpSession ssn = req.getSession();

ssn.setAttribute(eName, jspName); //Also tryied session to see if this
works

}

oCms.setResponse(cms, file);

oCms.showResource(cms, file);

}

} catch (IOException e)

{

} catch (CmsException e)

{

}

String s = "";

return s.getBytes();

}

}

In JSP I have following line 
 
<% String screenJsp = (String)session.getAttribute("screenJsp"); 
System.out.println(screenJsp);
%>
<jsp:include page="<%= screenJsp %>" flush="true" /> 

 
What I am trying to do is.
Define a Master JSP template with include tag like defined above. Create
a OpenCMS Element template file. The element template will have
ELEMENTDEF defined for each jsp include tag with a Paramenter having the
value of Path to JSP file.
In JSPTemplate class I will read name of Elemendef and Template file
paratmeter and save in Attribute collection of request of Session
object. I will read values of each include file  in the JSP master
template and set the values, Like this I can get a JSP file prepared for
rendering.
This will provide template support to JSP.
 
I don't know how good I explained this situation but If you have my
Velocity template doc, that will help, because I am trying to do this in
samilar way.
 
Regards
Anil Patel
