[opencms-dev] Flex Session variable

[Anil K Patel]

NachrichtAlex,

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
