Unable to display images on Delivery stage (WEM 8.1)

Hi,

I am using WEM 8.1 and Primefaces(JSF) for designing pages for my application.

The issue is:

On deploying application on the management stage, where CMA and CDS are both on the same server, all the content as well as images are being displayed on the pages.

But when I deploy application on the Delivery stage (CDS on different server), the text related content is published, but the images are not getting dispayed. What can be the reason for it? No error is displayed in the log.

I have followed all the steps from "OpenText Web Experience Management 8.1 Content Delivery SDK Development Guide".

Just one step has been missed i.e, Placing vgn-appsvcs-cda.tld in the web application. According to the doc, there should be a vgn-appsvcs-cda.tld file in a vgn-appsvcs-cda.war located at installDir/Content/8_1/lib/sdk. But the vgn-appsvcs-cda.war file is not present at the specified location. I tried finding the tld file in other jars and wars but didn't find it. Where can I get the vgn-appsvcs-cda.tld file ?

Is there any other option for displaying the images? Or am I missing any other part?

Thanks in Advance!!!

Please go through the (7) point of 10.2 section (Configuring Dynamic Portal or Dynamic Site on the Delivery Stage) in the OpenText Web Experience Management Dynamic Site and Portal Modules 8.1 – Configuration Guide

I have pasted the content here for your convenience

In theURL Path Prefixpane, specify a URL prefix path as instructed, and click

Next.

10.2 Configuring Dynamic Portal or Dynamic Site on the Delivery Stage

WCDPSM080100-ACC-EN-1 Configuration Guide 121

When a static file that is part of a preview template or page is published,

Dynamic Portal/Dynamic Site on your delivery stage builds links based on the

following components:

•The Static Content Directory path you specified when you created the

delivery stage (seestep 2).

•The URL path prefix that you specify in this step. The URL path prefix is the

context for viewing your static file content from a browser.

•The static file placement path as seen in the Management Console.

For example, say that you supply values as follows:

•Static content directory:

C:\Program Files\Apache Software Foundation\

Tomcat 6.0.14\webapps\myCDA\myStaticFiles\

•URL path prefix:

/myCDA/myStaticFiles

As implied by the static content directory value, you have a Tomcat delivery

application server (servlet engine) installed in the following location:

C:\Program Files\Apache Software Foundation\Tomcat 6.0.14\

Assume that your CDA (myCDA) is deployed on host myDelHoston port 8080.

You now publish a static file namedimg19.jpgthat has the following project

path:SiteA/ChannelZ.

To accessimg19.jpgfrom a browser, you would use the following URL:

http://myDelHost:8080/myCDA/myStaticFiles/

SiteA/ChannelZ/img19.jpg

To accessimg19.jpgfrommyDelHostfile system, you would look in the

following directory:

C:\Program Files\Apache Software Foundation\

Tomcat 6.0.14\webapps\myCDA\myStaticFiles\

SiteA\ChannelZ\img19.jpg

Hi Pramod,

Thanks for the reply. But We haven't used the OpenText Dynamic Portal.
We have used our own Portal framework with JSF and xhtml. Will the same be applicable for it?

I had previously added the URL Path Prefix but it requires an image tag where this URL path is used as a resource name. Below, I have added a part of sdk doc which I referred:

" - VgnImgTag Overview

Like its sibling the VgnContentLink tag, the VgnImgTag is intended to support

your business as you deploy JSPs across multiple stages. The VgnImgTag, which

extends the Struts html:image tag, provides a mechanism for you to use different

image servers for each stage so that your images can render properly without

having to modify the JSPs as they are deployed across those stages.

In its most simple form, the tag includes two attributes, resourceName and src, as

shown in the following example:

<cda:img resourceName="myResourceName" src="/my/path/to/image.gif" />

In this example, ʺmyResourceNameʺ refers the resourceName you define for the

URL path prefix (See Defining Resources for VgnImgTag on page 192), both on the

Management stage and the production stage.

Following are URL path prefix examples for the Management and production

stages:

• The Management stage URL path prefix might point to

ʺhttp://myMgmtImageServer:80/AppConsoleʺ.

• The production stage URL path prefix might point to

ʺhttp://myLiveImageServer:80/AppConsoleʺ.

The tag works by retrieving the URL path prefix and prepending it to the src or

srcKey attribute to build the proper image path. As the JSP with the tag is deployed

from the Management stage to the production stage, the tag selects the proper URL

path prefix and generates something like the following:

<img src="http://myMgmtImageServer:80/AppConsole/my/path/to/image.gif">

and

<img src="http://myLiveImageServer:80/AppConsole/my/path/to/image.gif">

respectively. This prevents you from having to hand modify each JSP as it is

deployed in order to reference the image different servers. "

But this tag is present in the vgn-appsvcs-cda.tld tag library which i am unable to find.

Thanks!!

Hi,

Previously I was using a Media CCE Widget for the image attributes in the CTD. I also tried using File Widget for the same. I also tried configuring the URL Path Prefix but probably there is some issue with the path of images on the delivery stage, as the same thing works well on the management stage.

Can anybody help on this please?

Thanks!!!

1. deploy webapplication on delivery stage2. Check urlpathprefix at Configuration Console>Content>Delivery Services>Content Delivery Stage - StageName>Content Delivery Services - Name>Resources>Resource Type -URLPathPrefix>Resource - static_file>URLPathPrefix Resource3. in your contentview script file use these (if you use File widget) : a: <%@ taglib uri="/WEB-INF/vgnExtTemplating.tld" prefix="templating" %>........... ...........

b: String imageURL = ""; try { StaticFile sf = PageUtil.getStaticFile(managedObject.getAttributeValue("image").toString()); imageURL = PageUtil.getStaticFilePath(sf, rc); } catch (Exception ex) { //out.println("error"); }I hope, this snipped code wil help you.________________________________ïÔ: eLink Entry: Discussion Group - Web Experience Management [v7webcontentmanagement@elinkkc.opentext.com]ïÔÐÒÁ×ÌÅÎÏ: 3 ÏËÔÑÂÒÑ 2013 Ç. 13:22To: eLink RecipientôÅÍÁ: RE Unable to display images on Delivery stage (WEM 8.1)RE Unable to display images on Delivery stage (WEM 8.1) Posted by ali@smg.sanmiguel.com.ph (Li, Andy) On 10-03-2013 05:18Hi,Previously I was using a Media CCE Widget for the image attributes in the CTD.

Hi Evgeniy,

Thanks a lot for your reply!!!

I tried doing it, but did not work. I need a JAVA Code to retreive static file without using DPM/DSM.

Can you please help for the same?

Thanks!!
