Struts 2 - Converting new lines (\r\n) in <br /> elements using <s:property>

Is there a 开发者_C百科way to convert new lines in a <br /> HTML element using the <s:property> tag?

For example I have the following string value in a sampleValue property:

Hello world\r\nThis is a new line

to be rendered with <s:property value="%{sampleValue}" /> like:

Hello world<br />This is a new line

Thanks

Sorry for dredging this up, but now that I figured it out, I wanted a place to post the solution in case I needed it again. ;?)

<s:property escapeHtml="false" value="sampleValue.replace(\"\n\", \" <br />\")" />

There is no facility in struts2 for this. If for some reason you have preformated the text, then I guess the easiest would be:

<pre>
  <s:property value="sampleValue"/>
</pre>

It is possible of course to get a regex into the display to replace "\r\n" with <br/> but there is something very ugly about that (I also find the solution above with <pre> quite ugly too but most will find that easier to understand than a regex in the middle of a jsp).

Note: Instead of <pre> you can use the css property "white-space" with a value of "pre" see: http://www.w3schools.com/css/pr_text_white-space.asp for more information on the css white space property.

Yes, struts obviously escapes by default all meta-signs ... just do the following:

<s:fielderror escape="false" />
<s:actionmessage escape="false" />

and the linebreak should work.

Just try this:

Line of code in java file:

datos += rs.getString(7) + "<br/>"; 

Line of code in .jsp file:

<s:property escapeHtml="false" value="datos" />
