Thanks for the kudos. You're too kind. I agree with Doug's suggestion about where to start with validation. By the way, for any FCKeditor work I recommend using FireFox and its LiveHttpHeaders or TamperData plugin (so you can really see what is being transmitted back & forth). Also, I intend to rename FredSaveAction.java to FCKeditorSaveAction.java, and UploadFredAction.java to FCKeditorUploadAction.java. Now, here are some raw notes I took last month when I was last working on the save portion. This might help you take it to the next level. It contains some output from the TamperData FireFox plugin. ------------------- Q: what does the output of the fckeditor look like for a save? It contains 2 values in an HTTP POST values: hidparam and content: 9:23:20.061[100ms][total 140ms] Status: 200[OK] POST http://localhost:8800/default/authoring/junk5_en.html?lenya.usecase=fckeditor&lenya.step=edit Load Flags[VALIDATE_ONCE_PER_SESSION LOAD_DOCUMENT_URI LOAD_INITIAL_DOCUMENT_URI ] Content Size[-1] Mime Type[text/html] Request Headers: Host[localhost:8800] User-Agent[Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7] Accept[text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5] Accept-Language[en-us,en;q=0.8,ar-iq;q=0.5,be;q=0.3] Accept-Encoding[gzip,deflate] Accept-Charset[ISO-8859-1,utf-8;q=0.7,*;q=0.7] Keep-Alive[300] Connection[keep-alive] Referer[http://localhost:8800/default/authoring/junk5_en.html?&lenya.event=edit&lenya.usecase=fckeditor&lenya.step=open] Cookie[JSESSIONID=t6ofokqn99pd; url=default/junk5_en] Post Data: hidParam[saveIcon] content[I+am+the+content.] Request Headers: Date[Sat, 17 Dec 2005 14:23:20 GMT] Server[Jetty/4.2.23 (Windows XP/5.1 x86 java/1.4.2_08)] X-Cocoon-Version[2.1.7] Content-Type[text/html; charset=utf-8] Transfer-Encoding[chunked] Q: What does Lenya do with that request? It goes into usecase-fckeditor.xmap line 203, which calls the fckeditorSave resource at line 80. That calls FredEditorSave.java, passing in the name of the temporary file to save (in work dir) and the schema file name (xhtml.rng). Q: what does FredSaveAction.java do? A: It saves the value of the "content" parameter passed from the request (the HTTP POST) into a temporary file (in the "work" directory tree), which looks like this: <?xml version="1.0" encoding="UTF-8"?> <body> <h1>Default Publication</h1> <p>Welcome to the default Lenya publication!</p> This is a test </body> after my recent change to FredSaveAction.java it looks like this: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";> <html xhtml:dummy="FIXME:keepNamespace" lenya:dummy="FIXME:keepNamespace" dcterms:dummy="FIXME:keepNamespace" dc:dummy="FIXME:keepNamespace" xmlns="http://www.w3.org/1999/xhtml"; xmlns:xhtml="http://www.w3.org/1999/xhtml"; xmlns:lenya="http://apache.org/cocoon/lenya/page-envelope/1.0"; xmlns:dcterms="http://purl.org/dc/terms/"; xmlns:dc="http://purl.org/dc/elements/1.1/";><body> This is a test </body></html> Then it calls 1) "DocumentHelper.readDocument(file);" to verify well-formedness, then "RelaxNG.validate(schema, file);" to validate against the XHTML schema. At this point an http connection is made to www.w3.org, presumably to get the xhtml schema. (note: there is a copy of the dtd within Lenya's webapp/entities directory, but I don't know how to tell Lenya to use it. I suppose I would have to form a cocoon URI and set a pipeline to find that file based on that URI.) Q: Then usecase-fckeditor.xmap calls the "editDocument" function (with the cocoon:/request2document URI request2document is a pipeline in the same xmap file which a) reads in the temporary file from the work area, transforms it via savedContent.xsl (which adds the header, namespaces, dublin core meta values, copies <body> node from the temporary xml source file, and closes the </html>)). The edit-document.js file then runs, copying this generate HTML file from the work area to the original document file location, overwriting the original. Then it "checks in" the file and triggers the "edit" workflow. Mabe this generated file is what we need to validate, rather than the raw temporary file that FredSaveAction generates. But the problem is, that generated file lackes any <body> node (hence is missing all content). The xsl file is apparently failing to find the <body> tag in the work file. But why does validation have to be so complicated? What if, instead, we had a pipeline that did this: 1) received posted/putted info (StreamGenerator? RequestGenerator?) 2) add header/footer if necessary to make XML/XHTML compliant 3) run through XML & RelaxNG schema validation (org.apache.lenya.cms.cocoon.acting.ValidateAction.java -exists!) 4) overwrite original file with this new contents 5) trigger "edit" workflow 6) return a message to the browser The problem is that FCKeditor doesn't emit valid XML (it doesn't have an outermost container element, and it doesn't define the namespaces for HTML entities that it uses). Fixed by adding DOCTYPE header to FredSaveAction.java. Deployed the following files to dev for testin: FredSaveAction.java (& FredSaveAction.class) usecase-fckeditor.xmap Other Editors: 1) KUPU: Kupu does an HTTP PUT to send the following to /default/authoring/junk5_en.html?lenya.usecase=kupu&lenya.step=save: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";> <html xmlns="http://www.w3.org/1999/xhtml";><head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /><title>Default Publication</title> <link href="/default/authoring/css/page.css" rel="stylesheet" /> <meta http-equiv="Content-Type" content="text/html;charset=utf-8" /></head><body>My Content </body></html> This invokes usecase-kupu.xmap, which does this: - verify that the document is checked out - 2) BXE Editor: BXE does schema validation on the fly as you edit, so it doesn't need to validate after saving (???). It sends the following as an HTTP PUT to /default/authoring/junk5_en.html?lenya.usecase=bxeng&lenya.step=xml&exit=false when the save icon is pressed: <?xml version="1.0" encoding="UTF-8" ?> <xhtml:html xmlns:xhtml="http://www.w3.org/1999/xhtml"; xmlns:dc="http://purl.org/dc/elements/1.1/"; xmlns:dcterms="http://purl.org/dc/terms/"; xmlns:lenya="http://apache.org/cocoon/lenya/page-envelope/1.0"; dc:dummy="FIXME:keepNamespace" dcterms:dummy="FIXME:keepNamespace" lenya:dummy="FIXME:keepNamespace" xhtml:dummy="FIXME:keepNamespace"> <lenya:meta> <dc:title>dctitle</dc:title> <dc:creator>Levi Vanya</dc:creator> <dc:subject>dcsubject</dc:subject> <dc:description>Abstract that can be used on an overview page</dc:description> <dc:publisher/> <dc:contributor/> <dc:date>Wed Dec 14 16:53:06 EST 2005</dc:date> <dc:type/> <dc:format/> <dc:identifier/> <dc:source/> <dc:language>en</dc:language> <dc:relation/> <dc:coverage/> <dc:rights>dcrights</dc:rights> </lenya:meta> <xhtml:head> <xhtml:title>Default Publication</xhtml:title> </xhtml:head> <xhtml:body> <xhtml:h1>Â </xhtml:h1> <xhtml:p>harner -xxx</xhtml:p></xhtml:body> </xhtml:html> 3) Forms Editor: This seems to only sends the changes to the server, as a POST like this: lenya.event=edit& <xupdate:insert-after select="/*/xhtml:body/xhtml:[EMAIL PROTECTED]'tag.0.2.0']"/> <xupdate:insert-after select="/*/xhtml:body/xhtml:[EMAIL PROTECTED]'tag.0.2.1']"/> <xupdate:insert-after select="/*/xhtml:body/xhtml:[EMAIL PROTECTED]'tag.0.2.2']"/> save=SAVE Every click in the editor seems to go back to the server as an HTTP POST, and is validated.
