Question

I have a ‘small’ problem. In a database documents contain a richtextfield. The richtextfield contains a profile picture of a certain contact. The problem is that this content is not saved as mime and therefore I can not calculate the url of the image.

I’m using a pojo to retrieve data from the person profile and use this in my xpage control to display its contents. I need to build a convert agent which takes the content of the richtextitem and converts it to mime to be able to calculate the url something like

http://host/database.nsf/($users)/D40FE4181F2B86CCC12579AB0047BD22/Photo/M2?OpenElement

Could someone help me with converting the contents of the richtextitem to mime? When I check for embedded objects in the rt field there are none. When I get the content of the field as stream and save it to a new richtext field using the following code. But the new field is not created somehow.

System.out.println("check if document contains a field with name "+fieldName);
        if(!doc.hasItem(fieldName)){
            throw new PictureConvertException("Could not locate richtextitem with name"+fieldName);
        }


        RichTextItem pictureField = (RichTextItem) doc.getFirstItem(fieldName);

        System.out.println("Its a richtextfield..");
        System.out.println("Copy field to backup field");

        if(doc.hasItem("old_"+fieldName)){

            doc.removeItem("old_"+fieldName);

        }


        pictureField.copyItemToDocument(doc, "old_"+fieldName);     

//      Vector embeddedPictures = pictureField.getEmbeddedObjects();
//      System.out.println(doc.hasEmbedded());
//      System.out.println("Retrieved embedded objects");
//      if(embeddedPictures.isEmpty()){
//          throw new PictureConvertException("No embedded objects could be found.");
//      }
//      


//      EmbeddedObject photo = (EmbeddedObject) embeddedPictures.get(0);
        System.out.println("Create inputstream");

        //s.setConvertMime(false);
        InputStream iStream = pictureField.getInputStream();
        System.out.println("Create notesstream");
        Stream nStream = s.createStream();
        nStream.setContents(iStream);

        System.out.println("Create mime entity");

        MIMEEntity mEntity = doc.createMIMEEntity("PictureTest");
        MIMEHeader cdheader = mEntity.createHeader("Content-Disposition");
        System.out.println("Set header withfilename picture.gif");

        cdheader.setHeaderVal("attachment;filename=picture.gif");
        System.out.println("Setcontent type header");
        MIMEHeader cidheader = mEntity.createHeader("Content-ID");
        cidheader.setHeaderVal("picture.gif");
        System.out.println("Set content from stream");
        mEntity.setContentFromBytes(nStream, "application/gif", mEntity.ENC_IDENTITY_BINARY);
        System.out.println("Save document..");

        doc.save();
        //s.setConvertMime(true);


        System.out.println("Done");

        // Clean up if we are done..

        //doc.removeItem(fieldName);

Its been a little while now and I didn’t go down the route of converting existing data to mime. I could not get it to work and after some more research it seemed to be unnecessary. Because the issue is about displaying images bound to a richtextbox I did some research on how to compute the url for an image and I came up with the following lines of code:

function getImageURL(doc:NotesDocument, strRTItem,strFileType){
    if(doc!=null && !"".equals(strRTItem)){
        var rtItem = doc.getFirstItem(strRTItem);
        if(rtItem!=null){
            var personelDB = doc.getParentDatabase();
            var dbURL = getDBUrl(personelDB);
            var imageURL:java.lang.StringBuffer = new java.lang.StringBuffer(dbURL);

            if("file".equals(strFileType)){
                var embeddedObjects:java.util.Vector = rtItem.getEmbeddedObjects();
                if(!embeddedObjects.isEmpty()){
                    var file:NotesEmbeddedObject = embeddedObjects.get(0); 

                    imageURL.append("(lookupView)\\");
                    imageURL.append(doc.getUniversalID());
                    imageURL.append("\\$File\\");
                    imageURL.append(file.getName());
                    imageURL.append("?Open");

                }
            }else{              
                imageURL.append(doc.getUniversalID());
                imageURL.append("/"+strRTItem+"/");
                if(rtItem instanceof lotus.domino.local.RichTextItem){
                    imageURL.append("0.C4?OpenElement");
                }else{
                    imageURL.append("M2?OpenElement");
                }
            }
            return imageURL.toString()
        }
    }
}

It will check if a given RT field is present. If this is the case it assumes a few things:

• If there are files in the rtfield the first file is the picture to display
• else it will create a specified url if the item is of type Rt otherwhise it will assume it is a mime entity and will generate another url.
