Hi All,

   I am getting error while trying to execute xupdate query:

 

   i am trying the following code:

 

import org.xmldb.api.base.*;
import org.xmldb.api.modules.*;
import org.xmldb.api.*;

public class StudentsXupdate {
   public static void main(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/studentsdb");

            String xupd = "<xupdate:modifications version=\"1.0\"" + " xmlns:xupdate=\"http://www.xmldb.org/xupdate\">";
            xupd+="   <xupdate:update select=\"/students/[EMAIL PROTECTED] = '781111']\">" ;
   xupd+= "781114" + "   </xupdate:update>" + "</xupdate:modifications>";

            XUpdateQueryService service =
               (XUpdateQueryService) col.getService("XUpdateQueryService", "1.0");

            long num=service.update(xupd);
            System.out.println("number is: "+num);
      }
      catch (XMLDBException e) {
         System.err.println("XML:DB Exception occurred " + e.errorCode);
      }
      finally {
          if (col != null) { col.close();}
      }
   }
}

 

here is my document:

C:\>xindice rd -c xmldb:xindice://localhost:8080/db/studentsdb -n students
trying to register database
<?xml version="1.0"?>
<students>
   <student sid="781111">
      <name>Laxma R Dendi</name>
      <degree>M.S</degree>
      <major>Computer Science</major>
   </student>
   <student sid="999999">
      <name>Guest</name>
      <degree>M.S</degree>
      <major>Computer Science</major>
   </student>
</students>

 

 

i am getting the following error:

 

C:\>java StudentsXupdate
