Re: Updating Xindice with Request Data

Fri, 03 Feb 2006 16:01:16 -0800

Hi Mike!

We don't had a function call createDocument.

All we use is the default function of _javascript_, Like loadDocument, we had a blank doc to be a template, load it than save it.
 
Yes we use binding, It's almost the same to load and save a XML file in filesystem or Xindice.

If you want to do more like deleteDocument I said before, you must define it yourself, like the sample of java below, put the java class to cocoon/WEB-INF/classes...than you can use it in flowscript.

Thanks Johnson,

In closing, would you tell me where the createDocument, loadDocument and saveDocument flowscript methods are locates/how do we use them? Or alternatively if we have to, how do you create them? On the cocoon Wiki some of the examples show code for these methods but before I attempt to implement them, is there an easier way to get them?

At present the cocoon stack trace returns
ReferenceError: "createDocument" is not defined. (file:/home/msc/dev/server/apache-tomcat-5.5.12/webapps/xwiki/forms/flow.js; line 14)

I notice that you also use binding. It this a requirement or can you do this operation using just the Forms block.

Cheers,

MIke

You're welcome, additional info, if you want delete or do something more than load and save document from Xindice, you must write some java  class like this to achive it.
 
package org.apache.xindice.examples;
 
import org.xmldb.api.base.*;
import org.xmldb.api.modules.*;
import org.xmldb.api.*;
 
import java.io.*;
 
public class ShpkXIN {
public static void deleteDocument(String args) throws Exception {
 Collection col = null;
 try {
  String driver = "org.apache.xindice.client.xmldb.DatabaseImpl";
  Class c = Class.forName(driver);
 
  Database database = (Database) c.newInstance();
  DatabaseManager.registerDatabase(database);
  col = DatabaseManager.getCollection("xmldb:xindice://localhost:8080/db/shpk");
 
  Resource document = col.getResource(args);
  col.removeResource(document);
 }
 catch (XMLDBException e) {
  System.err.println("XML:DB Exception occured " + e.errorCode);
 }
 finally {
  if (col != null) {
   col.close();
  }
 }
}
 
public static void retrieveDocument(String args) throws Exception {
 Collection col = null;
 try {
  String driver = "org.apache.xindice.client.xmldb.DatabaseImpl";
  Class c = Class.forName(driver);
 
  Database database = (Database) c.newInstance();
  DatabaseManager.registerDatabase(database);
  col = DatabaseManager.getCollection("xmldb:xindice://localhost:8080/db/shpk");
 
  XMLResource document = (XMLResource) col.getResource(args);
  if (document != null) {
   System.out.println("Document " + args);
   System.out.println(document.getContent());
  }
  else {
   System.out.println("Document not found");
  }
 }
 catch (XMLDBException e) {
  System.err.println("XML:DB Exception occured " + e.errorCode);
 }
 finally {
  if (col != null) {
   col.close();
  }
 }
}
 
}
and in flowscript
 
 var dao_xindice = new Packages.org.apache.xindice.examples.ShpkXIN();
 
 var button4 = form.lookupWidget("delete");
 button4. {
  var document = wid.shpk_cpdh.value + wid.rev.value + ".xml";
  dao_xindice.deleteDocument(document);
  form.load(blank);
  wid.shpk_jdrq.value = new java.util.Date();
  wid.shpk_xgrq.value = new java.util.Date();
  ls_rev = null;
  ls_tlc = null;
 }
even with OJB, you must write something linke this, not only sitemap.
with this method, you can easily treat XML DB like RDB.
 
best regards

Brilliant, that is exactly what I need... its not quite just a sitemap thing like I was hoping for, but it is good enough to get it all working. Thankyou to all!

Hi!

We use this method

var wid = form.lookupWidget();
form.createBinding("forms/shpk_bind.xml");
var documentURI = cocoon.parameters["documentURI"];
if (documentURI == "xmldb:xindice://localhost:8080/db/shpk/") {documentURI
= cocoon.parameters["documentURI2"];}
var document = loadDocument(documentURI);

  form.load(document);

....
saveDocument(document, "xmldb:xindice://localhost:8080/db/shpk/" +
wid.shpk_cpdh.value + wid.rev.value + ".xml");

Best Regards
