Getting HTML from any RichText item

HTML_logoLast week I blogged about sending the contents of a RichText field (including images and attachments) as an HTML mail. Today’s task was related: get the contents of a RichText item as HTML, knowing that the contents can be stored in the item as either MIME or standard RichText.

With the wrapDocument() function I showed you last week you can easily get MIME contents as HTML. It turns out that with some small changes you can use the same method to let Domino convert ‘standard’ RichText into HTML. You probably saw this in action already: create a document with RichText in the Notes client and edit it on the web. What’s new is that this method allows you to do it programmatically.

The trick is in the DominoRichTextItem class: it has two constructors to create it: using either a MIMEEntity or by giving it a RichTextItem. That’s all the info I needed to update my previous function:

/*
 * Wraps a lotus.domino.Document as a com.ibx.xsp.model.domino.wrapped.DominoDocument, including a RichText item
 *
 * @param doc document to be wrapped
 *
 * @param richTextItemName name of the rich text item containing standard RichText or MIME  contents that need to be wrapped
 */
private static DominoDocument wrapDocument(final Document doc, final String richTextItemName) throws NotesException {</code>

  DominoDocument wrappedDoc = null;

  Database db = doc.getParentDatabase();

  //disable MIME to RichText conversion
  db.getParent().setConvertMIME(false);

  //wrap the lotus.domino.Document as a lotus.domino.DominoDocument
  //see http://public.dhe.ibm.com/software/dw/lotus/Domino-Designer/JavaDocs/DesignerAPIs/com/ibm/xsp/model/domino/wrapped/DominoDocument.html
  wrappedDoc = DominoDocument.wrap(doc.getParentDatabase().getFilePath(), doc, null, null, false, null, null);

  //see http://public.dhe.ibm.com/software/dw/lotus/Domino-Designer/JavaDocs/DesignerAPIs/com/ibm/xsp/model/domino/wrapped/DominoRichTextItem.html
  DominoRichTextItem drti = null;

  Item itemRT = doc.getFirstItem(richTextItemName);

  if (null != itemRT) {

    if (itemRT.getType() == Item.RICHTEXT) {

      //create a DominoRichTextItem from the RichTextItem
      RichTextItem rt = (RichTextItem) itemRT;
      drti = new DominoRichTextItem(wrappedDoc, rt);

    } else if (itemRT.getType() == Item.MIME_PART) {

      //create a DominoRichTextItem from the Rich Text item that contains MIME
      MIMEEntity rtAsMime = doc.getMIMEEntity(richTextItemName);
      drti = new DominoRichTextItem(wrappedDoc, rtAsMime, richTextItemName);

    }
  }

  wrappedDoc.setRichTextItem(richTextItemName, drti);

  return wrappedDoc;

}

Using this function you can wrap any document and get the HTML from a RichText item:

View view = db.getView("someview");
Document doc = view.getFirstDocument();

DominoDocument ddoc = wrapDocument(doc, "Body");
DominoRichTextItem drti = ddoc.getRichTextItem("Body");

String html = drti.getHTML();
System.out.println(html);

Create HTML emails from RichText fields with embedded images and attachments

If you want to send formatted (HTML) emails from Domino you have a couple of options.

Starting with version 9, there’s a simple action that allows you to send HTML mail by just configuring some options. You can also use Tony McGuckin’s emailBean snippet to send an HTML mail from an XPage directly, including embedded images and/or attachments. And there’s also the SSJS snippet I wrote to send an email from any backend SSJS script.

Unfortunately, none of these could do what I wanted: send an HTML mail with the contents based on a RichText field (stored as MIME), including any embedded images. With the standard photo upload option available in the XPage embedded CKEditor it’s real easy to add embedded images. Tony’s emailBean snippet came close, but it requires a DominoDocument object as a parameter and thus only works when used directly on the XPage where you create the content. In my case, I either wanted to pick a set of documents to be send or use a scheduled agent to do that.

So I investigated how I could create a DominoDocument from a standard document object.

First stop: this snippet that uses the .wrap() function of the DominoDocument object to wrap a standard document. That worked, but didn’t add the RichText fields to the wrapped document. So I dived deeper and found the JavaDocs for the DominoDocument here. Turns out that there is a getRichTextItem() function that returns a DominoRichTextItem. That object, the DominoRichTextItem, is also used in the emailBean code. The JavaDocs for the DominoRichTextItem describe that you can use a MIMEEntity to create one. The newly created DominoRichTextItem can then be attached to the wrapped DominoDocument.

Here’s the XSnippet I just added to wrap a document, including MIME.

For this to work you need to enable the “Store contents as HTML and MIME” option of the RichText field that you’re storing the HTMl in. When you’ve done that you can use the emailBean to create and send the email:

function sendEmailFromRichText() {
  DominoDocument wrappedDoc = wrapDocument(docMail, "body");

  //now we can pass the wrapped document, including the MIME contents to the EmailBean
  EmailBean emailBean = new  EmailBean();

  emailBean.setSendTo("someone@somewhere.com");
  emailBean.setSubject("Here's a mail");

  emailBean.setDocument(wrappedDoc);
  emailBean.setFieldName("body");

  emailBean.setBannerHTML("<p>Hi, "  + sendTo + "</p>");
  emailBean.setFooterHTML("<p>Kind regards, "  + senderName + "</p>");

  emailBean.setSenderEmail("i@dontexist.com");
  emailBean.setSenderName("Name of the sender");

  emailBean.send();
}

 *

 */
private static DominoDocument wrapDocument( final Document doc, final String richTextItemName ) throws NotesException {
     
  DominoDocument wrappedDoc = null;

  wrappedDoc.setRichTextItem(richTextItemName, drti);
     
  return wrappedDoc;
     
}

Considering a Domino upgrade to 9.0.1 FP1 or 9.0.2? Beware of custom Java security policies

If you have custom Java security policies in place on your Domino server (either through a modified java.policy or java.pol file) you might want to read this before you upgrade.

When I want to change to Java security policy on a Domino server I create a java.pol file in the jvm/lib/security folder and add everything I want. That folder also contains the default java.policy file, but you don’t want to add your changes in there: that file tends to get overwritten when doing a server upgrade.

Yesterday I got a report from a customer of an error message they received when using one of my applications. That error message (java.lang.reflect.InvocationTargetException) sounded like something was wrong with the Java security policy in place. I checked and was right: the java.pol file was gone! They recently upgraded from 9.0.1 to 9.0.1FP1 so I suspected that to have caused it. Strange, because with previous upgrades I’m sure that the file wasn’t touched.

So I tested it myself: I monitored the jvm/lib/security folder while installing the fix pack on a 9.0.1 (Windows 32 bit) server. What I saw is that during the install Windows explorer automatically redirects me from that folder to the Domino program folder, so it looks like the incremental installer completely deletes and reinstalls that folder.

Browsing through the fix list database I found this: SPR #KLYH9FNKLW: the JVM is upgraded in 9.0.1FP1 to 1.6 SR15FP1. That’s what probably caused this changed behaviour. That fix is also in 9.0.2 (not released yet) so I guess you’ll see the same behaviour when upgrading to that version. Just something to be aware of…

XPages Debug Toolbar – now as a plugin

In preparation for the session with Phil Riand on Bootstrap4XPages last week at IBM Connect (slides) I’ve been doing quite some work on the Bootstrap4XPages plugin. That got me pretty good up to speed with the subject of OSGi plugin development, so I decided to take another shot at a thing that had been on my todo list for way too long: create a plugin version of my XPages Debug Toolbar.

So I watched the NotesIn9 episode by Tim Tripcony on creating a global custom control again, applied what he described to the toolbar custom control and, to my surprise, it worked! As of last week the XPages Debug Toolbar version 4 can be downloaded from OpenNTF and installed server wide. That means easy access to it from all your applications and no need anymore to more copying all those design elements manually.
This is the Debug Toolbar v4
It turned out that the plugin version also solves one of the biggest annoyances of the toolbar: because of the XPages classloader architecture, you needed to “Clean” your applications way too often to deal with ClassCastExceptions (DebugToolbar incompatible with DebugToolbar).

Included also in release 4:

  • The number of toolbar messages and errors are now also shown when the toolbar is collapsed.
  • Easy access to global objects from the Inspector tab (view, database, facesContext, …).
  • Couple of minor UI changes. Or, more popular phrased, “Optimised for Retina screens!”.
  • Scope variables that use a number as a key (yes, that is allowed) are now correctly shown.
  • Built-in XPages Request Processing Lifecycle explorer (written by Tony McGuckin)
  • You can now dump a list of all design note signers.
  • Because it’s now a plugin, you can also log messages from the beforePageLoad event.
  • And as always: “various performance and scalability enhancements”. No, really.

I need to shout a big “THANK YOU” here to Christian Guedemann from Webgate Consulting. He helped me to optimise the code and refactored a huge chunk of SSJS code to Java. Great job and thanks!

Unfortunately this release has an issue that will be apparent the minute you install it: it shows up twice in the Designer controls palette. At IBM Connect last week we tried to solve that with some IBM help (thanks Tony McGuckin!),Look, it's a bug! but it looks like this is an issue in the Designer code that will hopefully be solved in a future version (that’s a hint if anyone from the Designer developer team reads this :-). Apart from the double palette entry, I’ve seen no other drawbacks.

Distributing components like this through an OSGi plugin is definitely the way forward and comes with a lot of advantages, so I would highly encourage you to install this version! If you want to try it out first, check out the demo.

Improve your Domino SSL configuration, make your server more secure

Recently, Stephen Wissel tweeted a link to the Qualys SSL Labs SSL Server Test. That site allows you to enter the URL of an (internet facing) server that has SSL enabled and can then perform a deep analysis of the SSL configuration of that server. You may or may not know that Secure Sockets Layer comes in different flavours: v2, v3, TLS (Transport Layer Security; SSL’s successor), and more. Also, an SSL configuration can support various Cipher Suites (some of which are less secure than other) or can be vulnerable for things like the BEAST attack. So it’s not like SSL is on or off: there’s a bit more nuance to that.

Most people reading this will probably now run off to the SSL Server Test and enter the URL to their IBM Domino server. So did I the first time I read about it. Go ahead, I’ll wait…

I guess you were expecting a straight A-grade, but were suprised (or shocked) you didn’t. My first score (on a vanilla Domino server) was an F. That shocked me, so I did a bit of research. I found out that just like in school you don’t get an A for free.

So what can you do to get a better score on a Domino server? Here are two of my personal recommendations:

Disable insecure negotiation

Described here and here this allows for a man-in-the-middle attack and is enabled by default in Domino. Easy fix: add SSL_DISABLE_RENEGOTIATE=1 to your notes.ini.

Disable older, less secury ciphers

Recent browsers support more secure ciphers (AES), but Domino by default still allows older, weaker ciphers (DES, RC4). You can configure what ciphers Domino should support:

  • Open your names.nsf and open the server or internet site document for your server/ site.
  • Go to the Security tab and click Edit
  • In the SSL security section click the Modify button in the SSL ciphers field
  • Disable the SSL ciphers you don’t want to allow anymore. The only two I have enabled are: RC4 encryption with 128-bit key and SHA-1 MAC AES encryption with 256-bit key. There is some debate on if you should enable RC4. I have enabled it, but leave the choice up to you.

Restart your server and run the SSL test again. That looks a lot better, doesn’t it? Now you can go to bed feeling a bit safer.

Disclaimer: I’m no security expert, but after performing some research I think you’re safer with these easy changes (and so do the Qualys SSL Labs). Please correct me if I’m wrong. Of course I won’t take any responsibility for any of these recommendations.
