Pass parameter from Portal to Region Layout. (DPM)

Evgeniy_Vassaev

I use OT Portal as a preview server on WEM 8.1

In portal's jsp page i put parameters to session (SessionUtils.setNamespacedAttribute(.....))

Next, i put a contentpuplisher portlet to the jsp page:

<vgn-portal:renderPortlet portletFriendlyID = "UcanBUY" >

<vgn-portal:onRenderSuccess>

<vgn-portal:insertPortletContent/>

</vgn-portal:onRenderSuccess>

<vgn-portal:onRenderFailure >

</vgn-portal:onRenderFailure >

</vgn-portal:renderPortlet >

Next, on the preview portal server i put to the contentpuplisher portlet a ContentList component.

Next, the component is associated with a region layout:

<%@ taglib uri="/WEB-INF/vgnExtTemplating.tld" prefix="templating" %>

............

<templating:initComponent var="component"/>

<templating:initRequestContext var="rc"/>

............

<h2>${component.title}</h2>

......

Enumeration<String> names = session.getAttributeNames();

.....................

Here is the region layout return empty list of sesiion's attributeNames.

How can i get params within the region layouts (document view, etc) from Portal?

Could anybody help us?

It's very urgent for us.

Did you try

RequestContext rc = PageUtil.getCurrentRequestContext(pageContext);

Enumeration<String> names = rc.getRequest().getSession().getAttributeNames();

Best regards

Nex! t, on the preview portal server i put to the contentpuplisher portlet a ContentList component.

Next, the component is associated with a region layout:

<%@ taglib uri="/WEB-INF/vgnExtTemplating.tld" prefix="templating" %>

How can i get pa! rams within the region layouts (document view, etc) from Portal?

Thank you for response.

Sorry for my english.

Yes, I did. This way was my first idea. But rc.getRequest().getSession().getAttributeNames() is empty.

Now I'm trying to use the next code:

<templating:initComponent var="component"/><templating:initRequestContext var="rc"/><%    RequestContext rc = PageUtil.getCurrentRequestContext(pageContext);    HashMap map = (HashMap) RequestUtil.getRequestAttributesMap(rc);    Set keys = map.keySet();    for (Iterator it = keys.iterator(); it.hasNext();) {        Object key = it.next();        Object value = map.get(key);        String classname = key.getClass().getName();        out.println(">>>>key (" + classname + ") | " + key + "<br>\n");        String valueClassname = value.getClass().getName();        out.println(">>>>value (" + valueClassname + ") | " + value + "<br>\n");    }    out.println("***************************************<br>\n");    Object portal = map.get("portalContext");    Field[] fields = portal.getClass().getFields();     out.println("<br>===FIELDS===<br>\n");    for (Field field : fields) {        String fieldname = field.getName();        out.println(fieldname + "<br>\n");    }    Method methods[] = portal.getClass().getDeclaredMethods();    out.println("<br>===METHODS===<br>\n");    for (Method method : methods) {        System.out.println(method+"<br>\n");    }

Object parameters[] = {};

Class classparameters[] = {};

Method getPortalRequestMethod = portal.getClass().getDeclaredMethod("getPortalRequest", classparameters);

Object portalRequestImpl = getPortalRequestMethod.invoke(portal, parameters);

Method getSessionMethod = portalRequestImpl.getClass().getDeclaredMethod("getSession", classparameters);

Object portalSession = getSessionMethod.invoke(portalRequestImpl, parameters);

out.println("portalSession " + portalSession + " = " + portalSession.getClass().getName()+"<br>\n");

.........................

So, i got the HttpSessionWrapper class, but I can not use it within the preview script and can not use this object directly, because of when I try to include the portal's library to my templating i get exceptions:

java.lang.ExceptionInInitializerError

at com.vignette.portal.log.Log.staticInit(Log.java:53)

at com.vignette.portal.log.Log.info(Log.java:322)

....

java.lang.NoClassDefFoundError: com/epicentric/crypto/internal/EncryptionBootstrap

and more .

Ok, I decide to use reflection API. Could I use more simple method for getting PortalSession or send parameters from portal's jsp to my CDA?

Thanks.

Ok. Thanks to all. I have solved this trouble.

RequestContext rc = PageUtil.getCurrentRequestContext(pageContext);

HashMap map = (HashMap) RequestUtil.getRequestAttributesMap(rc);

Object portal = map.get("portalContext");

Object parameters[] = {};

Class classparameters[] = {};

Method getPortalRequestMethod = portal.getClass().getDeclaredMethod("getPortalRequest", classparameters);

Object portalRequestImpl = getPortalRequestMethod.invoke(portal, parameters);

Method getSessionMethod = portalRequestImpl.getClass().getDeclaredMethod("getSession", classparameters);

Object portalSession = getSessionMethod.invoke(portalRequestImpl, parameters);

Method getAttributeNamesMethod = portalSession.getClass().getDeclaredMethod("getAttributeNames", classparameters);

Object attributeNames = getAttributeNamesMethod.invoke(portalSession, parameters);

try {

Enumeration en = (Enumeration) attributeNames;

Object parameters1[] = {"epi:session::ATTRIBUTE_NAME"};

Class classparameters1[] = {String.class};

Method getAttributeMethod = portalSession.getClass().getDeclaredMethod("getAttribute", classparameters1);

Object NEEDED_OBJECT= getAttributeMethod.invoke(portalSession, parameters1);

} catch (Exception ex) {

ex.printStackTrace();

}
