Re: nl2br taglib
Nice piece of work, it looks familiar... http://www.mail-archive.com/[EMAIL PROTECTED]/msg63442.html ...never thought feedback on the solution would be like this, but each to their own. For those interested, the link contains code which can be used for any such filter operation. Arron. I truly believe that nl2br would be a most excellent taglib. Already my web developer has thanked me 10 times for making this tag for him. Here is why. Often times the jsp developer needs to include a large about of descriptive text with paragraph breaks. Normally he/she would have to flood the document with br / tags to get the formatting (or p tags or whatever). By using this tag, the jsp developer can just type filter:nl2brThis is a lot of text But I need to have breaks in the text But I want to just copy from the text editor and not have to do further work./filter:nl2br I am thinking the filter could do other things, such as wordwrap, perhaps nl2p for p tags around the line break sections, and a horde of other options. Any one think a filter taglib set would be a good idea? If we are out to save the jsp developers time, this seems like a viable solution to me. I will post the code if anyone is interested, but it wanted that complex.

Yep, I took your advice, I had just lost the reference to who had
originally suggested it. I would have attached the code last time
but my stupid mail client is giving me an error and I have just too
flooded to play with configurations right now. Here it is.
package net.creativerge.taglib.filter;
import javax.servlet.jsp.JspException;
import javax.servlet.jsp.tagext.BodyContent;
import javax.servlet.jsp.tagext.BodyTagSupport;
public class Nl2brTag extends BodyTagSupport

{
return EVAL_BODY_BUFFERED;
}
public int doAfterBody() throws JspException
{
BodyContent bodyContent = getBodyContent();
if (bodyContent != null) {
String body = bodyContent.getString();
if (body != null)
{
body = body.replaceAll(\n, br /);
try
{
bodyContent.getEnclosingWriter().println(body);
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
return EVAL_PAGE;
}
}

Re: nl2br taglib
Attached is a hacked version of WriteTag.java from the struts library to include a nl2br attribute which will convert \n to br / in the output. It was a pretty simple hack and you can just update your .tld file to include the java class net.creativerge.struts.taglib.bean.WriteTag and change your .tld definition to include the nl2br attribute (just like the filter attribute) and you will be there. Someone can feel free to add this to bugzilla, but I have way too much on my plate right now to put up a fight.

Re: nl2br taglib
Dan,
I think that you may have better luck in a tag that doesn't actually extend or
particularly work around the write tag, but simply filters the results of body
content. That way your not just restricted to filering the content of a bean
property. Markup would be like...
mylib:nl2br whatever nested:write property=something //mylib:nl2br
...And in this would could get the advantages of nested tags or whatever form
you wanted. It also means you don't have to worry about blocking/supporting
the logic of any underlying tag.
The tag class itself would look like...
// import whatever
public class NL2BR extends BodyTagSupport {
public int doAfterBody() throws JspException {
if (bodyContent != null) {
String filteredContent = bodyContent.getString();
// filter here...
ResponseUtils.writePrevious(pageContext, filteredContent);
bodyContent.clearBody();
}
}
}
...this should, in theory, do the trick. No properties or anything, simply
filter whatever comes through in the body content.
Arron.
