Using JSTL xml tags with DPM

Dexter_Ellingson

Hello. We are on WEM/DPM 8.5 and Portal 8.5.

I am trying to parse the xml returned by a Navigation content component on a display view using xml JSTL tags. An exception is thrown when the <x:set> tag is used:

[8/4/15 9:42:37:684 CDT] 00000026 ServletWrappe E com.ibm.ws.webcontainer.servlet.ServletWrapper service SRVE0068E: Uncaught exception created in one of the service methods of the servlet /views/shared/shrBreadcrumbView.jsp in application sites. Exception created : com.ibm.websphere.servlet.error.ServletErrorReport: org.apache.taglibs.standard.tag.common.xml.UnresolvableException: $requestScope:com.vignette.ext.templating.portlet.region.types
at org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:699)
at com.ibm._jsp._shrBreadcrumbView._jspService(_shrBreadcrumbView.java:120)
...

        at com.ibm._jsp._shrBreadcrumbView._jspService(_shrBreadcrumbView.java:109)
        ... 221 more

It appears the <x:set> tag iterates through all attributes in request scope and throws an exception if any are null. In this case, com.vignette.ext.templating.portlet.region.types is null. There are a few other null DPM attributes in request scope also.

Has anyone successfully used the JSTL xml tags to parse xml in a display view? Has anyone run into this issue? Any suggestions?

Thanks much.

Yes, and I've used something like this

<%-- declarations --%>

<%@ page import="com.vignette.as.config.ConfigUtil" %>

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

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<%@ taglib prefix="x" uri="http://java.sun.com/jsp/jstl/xml" %>

<%@ page contentType="text/html" %>

<%-- initialize component & results --%>

<templating:initComponent xml="xml"/>

<x:parse var="componentXml" xml="${xml}"/>

<templating:initRequestContext var="rc"/>

<c:set var="currentChannel" value="${rc.requestedChannelBean}"/>

<templating:contentItem result="content"/>

//<!-- the xml uncomment to see xml

//${xml}-->

<x:forEach select="$componentXml/VgnExtContentSelectComponent/contentItem/CTDname" varStatus="status">

Title: <x:out select="WFSIMPLE-TITLE" escapeXml="false"/>

</x:forEach>

Hi,

Not sure if this will help or not, but we have used DPM and JSTL tags as well. In your jsp, try and see if this will help as we have to set a few other things. We also don't use x:set but only x:out with c:set. With navigation using DPM, it seems to not like not having the jsp override or xsl override set to null. Maybe someone from OT can explain why.

<c:set var="vgnextregionttl" value="null.xsl" scope="request" /> //set scope to request and assign value so does not read it as null

<c:set var="vgnextxsloverrideuri" value="18000" scope="request" /> //same as aboe

<c:set var="com.vignette.ext.templating.portlet.region.xslOverrideUri" value="null.xsl" scope="request" />

<%-- initialize component & results --%>

<templating:initComponent xml="xml"/> //initializes xml

<templating:initRequestContext var="rc"/>

<x:parse var="componentXml" xml="${xml}"/> //parse xml

<ul>

<%-- render --%>

<x:forEach select="$componentXml/channelXML/channel" varStatus="status">

<c:set var="vcmId"><x:out select="channelVCMId"/></c:set>

<c:set var="channelName"><x:out select="channelName"/></c:set>

....
