you save your tempfile, but when you delete it? Is it a temporary file, no?

No bother....the least I can do is to help out a fellow Cocoon afficionado, since I have received a lot of help myself. Gotta pass on the karma when you can. ;-)
However, I will copy this reply to the list, in case anyone else there has a similar issue. This way it will be in the archives for future reference or maybe someone will post it on the Cocoon Wiki? (hint...hint.... ;-) ).
Try SourceWritingTransformer from the sitemap or else
cocoon.processPipelineTo from a flowscript.
<I decided to bite the bullet and add flowscript to my app....it worked <perfectly!
would you please be so kind and give me a short outline of this solution? I'm
having a similar problem for weeks, but there was nothing is sight.
Sure thing. Here is what I did (salient parts only...not a full working example):
I have a flowscript called "saveToFile.flow" (I call my flowscripts *.flow to distinguish them from normal client side javascripts, but you can call them *.js if you want), source attached to this email.
In my sitemap, in the <map:components> section I have the following entry:
<map:flow-interpreters default="JavaScript"/>
Then I include a flow definition later in the sitemap:
<map:flow language="javascript"> <map:script src="scripts/saveToFile.flow"/> </map:flow>
Which will cause Cocoon to load the flowscript and make it available for execution in pipelines. (Note: you may need a pipeline to source the scripts/*.flow files using a simple Cocoon reader. I assume you know enough about cocoon to put that in place).
Then I have a pipeline that looks like this, to actually execute the flowscript and save the output of a particular pipeline:
<map:pipeline> <map:match pattern="saveFile.html"> <map:call function="saveToFile"/> <map:select type="request-attribute"> <map:parameter name="attribute-name" value="centralPrint.status"/> <map:when test="success"> <!-- Do something useful here, since the saveToFile succeeded --> ..... </map:when> <map:otherwise> <map:read src="html/saveToFileFailed.html" mime-type="text/html"/> </map:otherwise> </map:select> </map:match> </map:pipeline>
Then there is a pipeline that generates the actual output that you want to save, which in my example, is output.xml. Note that the flowscript saveToFile.flow references output.xml, which is how it initiates execution of the following pipeline:
<map:pipeline internal-only="true"> <map:match pattern="output.xml"> <map:generate type="file" src="xml/input.xml"/> <map:transform src="xsl/myTransform.xsl"/> <map:serialize type="xml"/> </map:match> </map:pipeline>
So....when the user accesses a url of the form "saveFile.html", Cocoon will execute the first pipeline above, which in turn calls the flowscript, which will then fire off the 2nd pipeline, and voila...your file is now saved in a temp directory with a unique name! The filename that was generated for the save is returned in a request attribute called saveToFile.tempFile, so you can get it later in your pipeline if you need to along with a status attribute so you know if it succeeded or not.
Hope this helps!
