Re: Writing output of pipeline to a file

[Anna Afonchenko]

Thank you all for answering me, but I still can't manage to do it. Here is my pipeline: <map:match pattern="test.html">     <map:generate src=""/>     <map:transform src=""/>     <map:serialize type="xml"/> <map:match>   Here is my writeToFile.xsl: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"   xmlns:fo=http://www.w3.org/1999/XSL/Format xmlns:redirect="org.apache.xalan.xslt.extensions.Redirect"  extension-element-prefixes="redirect"> <xsl:output method="xml"/>  <xsl:template match="/">  <xsl:copy-of select="*"/>  <redirect:open file="testWrite.xml"/>  <redirect:write file="testWrite.xml">   <xsl:copy-of select="*"/>  </redirect:write>  <redirect:close file="testWrite.xml"/>  </xsl:template> </xsl:stylesheet>   When I am running this, I get the following error message from the Cocoon: type fatal message Exception in HTMLGenerator.generate() description org.apache.cocoon.ProcessingException: Exception in HTMLGenerator.generate(): java.lang.NullPointerException sender org.apache.cocoon.servlet.CocoonServlet source Cocoon servlet request-uri If I remove all the redirect: lines, then I get the serialized input file, so the input is OK, obviously, I have some problems with this redirect: Can anybody please tell me what's wrong? Thank you very much for help.

I did it in a stylesheet like this :   <?xml version="1.0" encoding="ISO-8859-1"?> <xsl:stylesheet version="1.0"  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"   xmlns:redirect="org.apache.xalan.xslt.extensions.Redirect"  extension-element-prefixes="redirect">  <xsl:output method="xml" encoding="ISO-8859-1"/>  <xsl:template match="/">  <redirect:write file="{$path}">   <xsl:copy-of select="*"/>  </redirect:write>  <TEXTE>output for the client</TEXTE>  </xsl:template > </xsl:stylesheet> But there was problems with some configuration, so finally i did it in my Action who had to generate the XML.   If you have to duplicate your XML stream, one for saving, another for the client, i think you have to do this in an action. It generates the XML file and this one is next transformed/serialized.   <map:match pattern="some.html">     <map:act type="YourAction">     <map:generate src=""/>        <map:transform src=""/>     <map:serialize type="html"/> </map:match>   Ludovic ----- Original Message ----- From: Anna Afonchenko To: [EMAIL PROTECTED] Sent: Tuesday, December 17, 2002 3:09 PM Subject: Re: Writing output of pipeline to a file Hi Ludovic. Thank you for answering. Can you say what do you do to save this XML file? I mean, if I have the following pipeline: <map:match pattern="some.html">     <map:generate src=""/>     <map:transform src=""/>     <map:serialize type="xml"/> </map:match> this pipeline produces an xml file. What should I use in order to save this file as "some.xml".   Sorry for asking almost exactly the same, I just didn't understood from you answer what should I do. Thank you very much for help.   Anna ----- Original Message ----- From: Ludovic de Beaurepaire To: [EMAIL PROTECTED] Sent: Tuesday, December 17, 2002 4:03 PM Subject: Re: Writing output of pipeline to a file Hi Anna,   I had this problem and didn't find a solution for caching the output of the pipeline to perform an OutputAction as saving in a file. Finally i chose to save the XML, and to perfom the transformation/serialization when a request need the transformed file. It supposes that the transformers are not modified.   Another solution should be using the CommandLine classes to perform the pipeline in an action but i can't say more about it.   Hope a better solution exists...   Ludovic ----- Original Message ----- From: Anna Afonchenko To: cocoon-users Sent: Tuesday, December 17, 2002 2:19 PM Subject: Writing output of pipeline to a file Hello All! I know that today I ask too many questions, but since cocoon is new to me, sometimes I don't even know where to look for the information, so you are my only help. Thanks for everyone who took time to answer my questions. Here is another one:   At the end of the pipeline the result file is output to the browser. I need the result file also to be saved in the file on my hard drive. How can I do this? I read about the SourceWritingTransformer, but I understood that I can write <source:write> tag in xml only, not in xsl.   Or maybe I can use it to do what I need, and I just don't know how? Please tell me.   Thank you very much for your help.   Anna
