Stream Object Model

, ,
1

Hi everybody,

I am trying to insert XML Docs using the Stream Object Model! I get always the same error:

Reading from character input stream caused problems
NestedException:http://apache.org/xml/features/nonvalidating/load-external-dtd

Although if I try to do the same usin DOM Object Model, It works great!

Thx

hi fady,

do you - for testing - print the character stream before inserting?

you must not do this, as then the stream is “consumed”, that is “read empty”.

if this is not the case: how do you create the data stream? how do you pass it to the insert method?

regards,
andreas f.

Yes you are right, actually I was printing the string to see if the structure of the XML file was Ok. I removed it, and still it is not working!
Find attached the commented piece of code that might give you an idea on how I am doing to insert the stream.

Thx

Hi Fady,

What kind of error are you getting?

Here is an example of how to use the stream interface to insert a document.

import com.softwareag.tamino.db.api.accessor.TStreamAccessor;
import com.softwareag.tamino.db.api.accessor.TAccessLocation;
import com.softwareag.tamino.db.api.common.TException;
import com.softwareag.tamino.db.api.connection.TConnection;
import com.softwareag.tamino.db.api.connection.TConnectionFactory;
import com.softwareag.tamino.db.api.objectModel.TXMLObject;
import java.io.IOException;
 
public class StreamInsert
{
    public StreamInsert() throws IOException
    {
	try { 
          //Get Connection to the database
          TConnection connection =   TConnectionFactory.getInstance().newConnection("<Tamino URL>");
 
          //Get the Accessor to the appropriate Collection
          TStreamAccessor accessor = connection.newStreamAccessor(TAccessLocation.newInstance("<Collection>"));
          TXMLObject obj = TXMLObject.newInstance("<test>some stuff</test>");
          accessor.insert(obj);
          connection.close();
	} 
      catch (TException taminoException) {
          taminoException.printStackTrace();
      }
    }

    public static void main(String argv[]) throws IOException{
      StreamInsert si = new StreamInsert();
    }
}

Hello,

Well it worked but bizarre!

I uninstalled Tamino and removed all databses and then installed it again and created a fresh database with a new collection but the same schema. Then I used the SAME code, and there it worked!

Thx anyway!
