Displaying formatted rich text

eddparsons · #1

Hi,

I have some rich text stored in a database (example below) that I want to output on an Ebase page. Is there a way of displaying this with formatting?

Regards,
Edd

Edd,

You might try this rtfToHtml Javascript function, I got it from Google and converted it from Java to Javascript. Once you've got your rtf text, you could display it in a Text Control as shown below. You need to make sure that the Contains HTML option is checked for the Text Control. I tried this with your RTF text and it gave an answer but not the one I was expecting. But I suspect that was because the RTF text can't simply be copy/pasted.

Code: Select all

var rtfText = ".....";
var htmlText = rtfToHtml&#40;rtfText&#41;;
log&#40;htmlText &#41;;
controls.TEXT1.text.text = htmlText ;

function rtfToHtml&#40;rtfText&#41; 
&#123;
  var sr = new java.io.StringReader&#40;rtfText&#41;;
    var p = new javax.swing.JEditorPane&#40;&#41;;
    p.setContentType&#40;"text/rtf"&#41;;
    var kitRtf = p.getEditorKitForContentType&#40;"text/rtf"&#41;;
    try 
    &#123;
        kitRtf.read&#40;sr, p.getDocument&#40;&#41;, 0&#41;;
        kitRtf = null;
        var kitHtml = p.getEditorKitForContentType&#40;"text/html"&#41;;
        var writer = new java.io.StringWriter&#40;&#41;;
        kitHtml.write&#40;writer, p.getDocument&#40;&#41;, 0, p.getDocument&#40;&#41;.getLength&#40;&#41;&#41;;
        return writer.toString&#40;&#41;;
    &#125; 
    catch &#40;e&#41; 
    &#123;
        log&#40;e&#41;;
    &#125;
&#125;

I had a go at this as I could have done with a similar thing before but in the log I got:

Code: Select all

<html>
  <head>
    <style>
      <!--
      -->
    </style>
  </head>
  <body>
    <p>
      
    </p>
  </body>
</html>

I tried it with a couple of different rtf documents and got the same thing each time.

Hi

I think you may need some third party solution. I have not tested this, but you could download and compile this:

https://code.google.com/p/lnrt2html/sou ... l.java?r=1

You will need to put the compiled class in:

<ebase__install>/UfsServer/tomcat/webapps/ufs/WEB_INF/classes

You can then invoke this class using the Server Side JavaScript.

Thanks for your suggestion Steve.

I have compiled the class, saved in folder classes\com\bhivef\lnrt2html folder and impoted the class in a javascript using:

importPackage(com.bhivef.lnrt2html.*);

How do I then use this?

I've tried using:

var htmlText = RichText2Html(rtfText);

but I get the following:

ReferenceError: "RichText2Html" is not defined

As you may be able to tell I haven't really got a clue what I'm doing - any pointers would be gratefully received.

Edd

Hi,

When you import the package, you do not need to .* at the end. You are also wanting to call a static method, so you do not need to create a new instance of the Java Object. You want to invoke the method directly.

e.g

Code: Select all

importPackage&#40;com.bhivef.lnrt2html&#41;;

var htmlText = RichText2Html.parse&#40;rtfText, "Error Message"&#41;;

or you could invoke parse using the package name as well;

e.g

Code: Select all

var htmlText = com.bhivef.lnrt2html.RichText2Html.parse&#40;rtfText, "Error Message"&#41;;

Kind regards

Ok, I have the importPackage(com.bhivef.lnrt2html);

Then using

var htmlText = RichText2Html.parse(rtfText, "Error Message");

I get the same RichText2Html not defined error.

Using

var htmlText = com.bhivef.lnrt2html.RichText2Html.parse(rtfText, "Error Message");

I get the error below:

org.mozilla.javascript.EcmaError: TypeError: Cannot call property parse in object [JavaPackage com.bhivef.lnrt2html.RichText2Html]. It is not a function, it is "object". (RICHTEXTTEST#5)

Hi Edd,

Can you email the RichText2Html.java file to support@ebasetech.com and I will have a look for you.

Kind regards

Steve
