WPC - XSLT helpers

Hi
Is there anyone who has got experience in creating an own xslt helper?
I created an own xslt helper (just took the standard XsltHelperRuntimeLight and uploaded it under an own package).
I did the mapping in config. (System admin - System Config - KM - CM - WPC - editor - XSLT Helpers)
Now I'm getting the following error when I execute. Did I forget something?
Cannot render container :
com.sap.engine.lib.xml.util.NestedException:
Could not load class: com.company.nw.wpc.km.service.editor.xslt.XsltHelperRuntimeLight required for extension library.
-> java.lang.ClassNotFoundException: com.company.nw.wpc.km.service.editor.xslt.XsltHelperRuntimeLight
------------------------- Loader Info -------------------------
ClassLoader name: [com.sapportals.portal.prt.util.ApplicationClassLoader@18d88c3]
Parent loader name: [com.sapportals.portal.prt.util.ApplicationClassLoader@10e631f]
References: not registered! Resources: D:\usr\sap\NWD\JC00\j2ee\cluster\server0\apps\sap.com\irj\servlet_jsp\irj\root\WEB-INF\portal\portalapps\com.sap.nw.wpc.core\private\lib\com.sap.nw.wpc.core_core.jar
It seems my class isn't loaded..
I used this code to import my class in the xsl file
<xsl:stylesheet version="1.0"
     xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
     xmlns:test_wpc="com.company.nw.wpc.km.service.editor.xslt.XsltHelperRuntimeLight">
And this one to use it
<span class="wpcnew"><xsl:value-of disable-output-escaping="yes" select="test_wpc:getString('xsl.xmsg.new', string(document/@locale))"/></span>
When I use a standard class in stead of mine, it works perfectly. So I assume it's a class mapping issue or my class isn't loaded at all.
Thanks for any help, thoughts or information about this topic!

Unable to refer to custom resource bundle in WPC content rendered with xslt

Hi,
I need to use the resource bundle messages inside WPC content.
When rendered by standard xsl templates the call to XSLTHelper class is done to retrieve message from the standard SAP resource bundle com.sap.nw.wpc.bundles.core.properties, like this:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:wpc="com.sap.nw.wpc.km.service.editor.hslt.XsltHelperCore">
<xsl:value-of select="wpc:getString([key defined in sap bundle], string(/document/@locale))"/>
The problem is that helper class doesn't provide any API to use custom bundles.
I tried to create xslt helper (including config in KM), but that didn't succeed neither. It would return with error NoClassDefFound.
Could you please help on configuring xslt helper and registering it with xslt rendering engine for Web Page Composer? I could not find any how-to guides on xslt helpers for WPC.
Thanks in advance.

How to configure XSLT Helper for WPC content

Hi,
I'm trying to write my own XSLT Helper and use it when rendering content on WPC web pages. I didn't find any documentation on this topic, so I did mimicked what SAP does with their com.sap.nw.wpc.km.service.linkmanager.XsltHelper:
1. Wrote my little class that contains static method:
public class MyXslHelper
     public static String testMethod()
          return "response from MyXslHelper";
2. Added declaration of namespace and usage in xsl template:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:my_hlp="com.my.xsl.helper.MyXslHelper">
<xsl:value-of select="my_hlp:testMethod()"/>
3. Defined helper in Content Management->Web Page Composer->Editor->XSLT Helpers:
name=my_helper
alias=my_hlp
implementation=com.my.xsl.helper.MyXslHelper
description=My helper
PRT mode=*
This doesnt' work and when rendered throws exception java.lang.ClassNotFoundException: com.my.xsl.helper.MyXslHelper.
What are the steps that I'm missing? Does anyone have any documentation on how to configure xslt helpers?
Thanks in advance

WPC - Anonymous User Error

Hello,
I have some problems with displaying the site content for the anonymous user.
First, I specify that I've done all the steps provided as a solution in this thread: [Web page composer and end user;
Some of the containers from a web page are showed correctly but some are displaying the following error message:
"Cannot render container : com.sap.engine.lib.xml.util.NestedException: Function with name 'wpc:getHrefValue' not found in context library."
This container uses a Simple Link List - template and as a link item contains an external link; so trying to trace the error I saw that xsl file corresponding to the template calls a method 'wpc:getHrefValue' for displaying the hyperlink value and for unknown reasons this is not available for the anonymous user.
The same thing happens if the template uses an internal link and brings the error:
"Cannot render container : com.sap.engine.lib.xml.util.NestedException: Function with name 'wpc:getWebDavAccess' not found in context library." refering to the getWebDavAccess method.
The par file containing the xslt helpers should be visible to everyone so the only thing it can represent is the way the "wpc:" call is made - which I couldn't track it.
Please tell me if you have any clues on this issue.
Thanks,
Ioana

Hello Ioana,
May I enquire which SP of WPC you are on ?
Just out of curiosity as I keep getting an authentication pop up despite assigning read user access to anonymous users group.
Did you come across a similar problem ?

WPC Runtime Error in Customer Framework Page

Hi again,
after successful proof of concept of WPC we have integrated some WPC Pages and iViews in our standard roles. Pages are displayed well with default framework page.
But using customer specific framework (via portal url alias /portal/mySite and corresponding display rules) we get an error displaying wpc content in runtime:
Cannot render container : com.sap.engine.lib.xml.util.NestedException:
Could not load class: com.sap.nw.wpc.km.service. editor.xslt.XsltHelper
RuntimeStandard required for extension library. -> java.lang.ClassNotFoundException:
com.sap.nw.wpc.km.service. editor.xslt.XsltHelperRuntimeStandard Found in negative cache
I have checked SAP Note 1133788 (Com.sap.engine.lib.xml.util.NestedException in WPC) which seems to be related, but adjusting of XSLT Helpers for Editor setting does not fix the problem.
I mentioned that settings for standardruntime entry (com.sap.nw.wpc.km.service.editor.xslt.XsltHelperRuntimeStandard) should match to customer Alias insted of default portal, but changing these setting won't have any visible result.
If I use default framework page with customer layout wpc runtime will work - so we have a temporary solution, but we want to avoid changing default framework page.
Any hints or documentation?
Many thanks in advance

Hi Thorsten,
maybe you should have a look at this [one.|https://forums.sdn.sap.com/thread.jspa?threadID=599765&tstart=0]
I think it's the same thing that was mentioned in the SAP Note you provided. But maybe you extract some additional hints for yourself out of the posts.
Let me know, if you manage to solve the problem.

WPC custom webform error

Hi,
We are trying to develop custom webform in web page composer as mentioned in below how to guide / help document.
https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/2041eb17-6001-2b10-b08d-b95ce55fa9b7

We are using the same xml and xsl files mentioned in the document .
While preview or adding the site content to the page we are getting below error.

Appreciate any help.

Hi Jagadeesh,
the note tells you to go to System Administration -> System Configuration -> Knowledge Management -> Content Management -> Web Page Composer -> Editor -> XSLT Helpers
and check if there is a XSLT Helper with the following parameters:
name: anonymous
Alias: *
Implementation: com.sap.nw.wpc.km.service.editor.xslt.XsltHelperRuntimeStandard
Key for Description: Define helper for default
PRT Mode: *
If not, create one and restart the portal.
See if this helps,
Robert

Any helpers please on JAVA XSLT Tranformation

I have an XML file and a XSLT file How using a Java class can I tranform the document to XHTML (i.e html in XML format)

Follow this link:
http://xml.apache.org/xalan-j/samples.html
Good luck.

Testing XSLT in WPC

I'm wondering what methods folks are using when they are testing out XSLT changes. It appears as though one must bounce the portal in order for XSLT changes to take affect.
Is there an easier way to have a change to the XSLT for a document type take affect? I'd prefer to avoid cycling the portal everytime I make a change. The velocity of development is slowing to a halt.

Hi,
Check the Editor Service Cache in the below link:
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/b07754de-e048-2b10-a0a9-8b732cf54b2c
I would set the Default Time-To-live setting to 1, so that the cached content expires after 1 sec.

XSLT mapping - namespace problem?

Hello,
I am trying to proces a message with the following format:
<XMLMESSAGE xsi:nonamespaceSchemalocation='schema.xsd' >
   <ORDER>
     <HEADER>
     </HEADER>
     <ITEM>
     </ITEM
</ORDER>
<XMLMESSAGE>
the mapping (XSLT or message mapping) throws an exception. During runtime or test, this is the same.
The problem occurs, I think, because of the nonamespace atriibute. If a change or remove the value, the mapping is fine.
Does anybody know if I should save the file mentioned in the attribute somewhere? Or is there a workaround for this problem?
thnx, Paul
PS: we are using PI 7.0.

XSLT, problem with HTML

Hi,
I am using XSLT to generate a webpage using an XML file and a stylesheet. The HTML page is created fine however any HTML tag i.e. the break line tag comes out in the file as &lt.;BR&gt.; rather then <.BR.> (ignore the dots, just there so the form doesnt show them incorrectly). Any suggestions? Here is my code:

Your 1,000 lines of code were indented so deeply that they scrolled off the right side of my screen and were extremely inconvenient to read. So I didn't read it.
However. Your question claimed to be about XSLT but I didn't see any XSLT posted. That was sort of strange. Anyway, if you are generating character strings containing <BR> then what you see is what you have to expect. If you want a <BR> element then generate a <BR> element. Like the one you see in the XML example you posted. (What was the relevance of that example, anyway? I didn't get that either. Was it supposed to represent the input you hoped that code was generating, or something?)

Problem with x:transform function : translation with XSLT

I've got a problem with this code :
This is the XML file :
<%@taglib prefix="x" uri="http://java.sun.com/jstl/xml"%>
<%@taglib prefix="c" uri="http://java.sun.com/jstl/core"%>
<c:import var="xslDoc" url="test.xsl"/>
<x:transform xslt ="${xslDoc}">
<students>
<student id="1">
   <name>
     <first>John</first>
     <last>Smith</last>
     <middle>T</middle>
   </name>
   <grade>
     <points>72</points>
     <letter>C</letter>
   </grade>
</student>
</students>
</x:transform>This is the XSLT :
<xsl:stylesheet version="1.0"
     xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="students">
<html>
<head>
<title>XSLT Transform</title>
</head>
<body>
   <table border="1">
   <tr><th>First</th><th>Last</th>
<th>Points</th><th>Letter</th></tr>
   <xsl:apply-templates/>
   </table>
   </body>
</html>
</xsl:template>
<xsl:template match="student">
<tr>
   <td><xsl:value-of select="name/first"/></td>
   <td><xsl:value-of select="name/last"/></td>
   <td><xsl:value-of select="grade/points"/></td>
   <td><xsl:value-of select="grade/letter"/></td>
</tr>
</xsl:template>
</xsl:stylesheet>I use NetBeans 3.5.1 for compiling and testing, and on my machine all works fine.
But when i upload the code on the server i''ve this type of error :

org.apache.jasper.JasperException: access denied (java.util.PropertyPermission org.xml.sax.driver read)It seems a permission problem, but my experience with JSP is very poor , i've asked to control to my host
the policy of the folders but they didn't respond me yet.
Any suggestion ?
Thx for reading, and sorry for my rusty english :-P

Thanks.
I've already tried to insert the whole path. You mean this,right ?
<c:import var="xslDoc" url="http://www.domain.net/examples/test.xsl"/>I've searched a lot with google but i haven't find anything.
I've not searched a lot into the jakarta site, I'll do tomorrow, now it's
a bit late (1:45 AM in Italy :-0 ), so i think that i'll go to sleep.
Thanks for responding so soon!
I'll wait for your new infos.
Thanks again.
read you tomorrow.

How to convert xslt file into string

i'm writting a java program to use xslt to transform the xml file. i'm encountering the problem when i try to convert the xslt file into string. i've defined my utility class called 'XmlUtil' to carry out the operation of transform xml file through xslt. but in my main java program i need to convert both xml and xslt file into a string in order to input them in my function argument. my function argument is as follows:
String htmlString = XmlUtil.applyXsltString(xmlContent, xsltString);
i've already converted xmlcontent into string by using:
xmlContent = xmlContentBuffer.toString();
but i don't know how to convert 'xsltString' now ? i've searched the google for an hour but i cannot find the solution. anyone can help ?

I don't understand why you need load the XML and XLS files into a String. A Transformer can be constructed from a Source and there is a StreamSouce which can be constructed from an InputStream. The transform() method can take a Source as input and can produce a Result. There is no need to go near a String representation of either the input.

Use URL Parameters in WPC Pages

Hi all,
Is there anyway to pass url parameters when calling a wpc page? We would like to call a wpc page and pass a URL a parameter that would then be accessible to each individual component within the wpc page. Also, how can we read the url parameter in the XSLT for the component webforms? Any help would be appreciated.
Thanks and Regards,

That would come within flex.
In my case, there is a SAP CRM web application which has a push button. On click of this button, flex URL is called(ie., http://172.22.41.154/MH_Bluebook_Integration2.html). On click of that button I need to pass an Object ID, which is passed withing that flex URL, something like this:
http://172.22.41.154/MH_Bluebook_Integration2.html?objID=abcd
I need to receive 'abcd' in the flex. Any way we could modify the HTML wrapper to send this value to swf?

WPC News including Teaser on one step ?

Hi,
is there a way of creating a WPC News (i read already the howto minicarticle) and also have the teaser in one step ? It should be the same way as the old XMLForms : 2 XSLT sheet and 1 XML .
Creating 2 elements per news is redundant work
I don't find any hints how this can be accomplished....
Any ideas ?
Regards,
Kai

Hi, wanted to know if you were able to accomplish this task.
We have a similar scenario and would appreciate your insight on this.
Thanks

WPC: Access Java beans from XSL

Hi,
How can we access custom Java beans from within the XSLs used to render WPC webforms? Do we have to implement a custom XSLT Helper? I am able to access standard Java classes using the <xmlns> tag but when I try to reference our custom classes the WPC editor throws a ClassNotFound exception. Any help will be appreciated.
Thanks and Regards,
