I found it here.
http://jakarta.apache.org/taglibs/guidelines.html
I got the link from Tomcat bug database. If this link is not provided in any

Hi all,
A few weeks ago I read a document explaining guidelines on writing
custom tags. I remember I found it on taglibs site but now I cannot find it
there. Also is there any FAQ section there ?

NullPointerException - newbie question

[Lee Peik Feng]

Hi,
I'm using tomcat 5.0.18 and jakarta-taglibs-standard-1.0.4 with J2SDK
1.4.2, WinXP

I encounter the following exception :

java.lang.NullPointerException
 at org.apache.jasper.runtime.TagHandlerPool.get(TagHandlerPool.java:153)

..

java.lang.NullPointerException
 at
org.apache.jasper.runtime.TagHandlerPool.release(TagHandlerPool.java:191)


I suspect it is something related to taglib because my JSP was running
fine with tomcat 4 (4.1.29)
Could someone give me some hint on : what is the cause of this prob? how
to resolve this problem?
Please let me know whether there is any other information that I need to
provide.

Hope that someone could help me. Thank you.

Regards,
Peik Feng

Works: Struts + c:import w/ Tomcat 5.0.18!!!

[Timo --Blazko-- Boewing]

Hiho all,

Just for interest: with Tomcat 5.0.18 (prior: 5.0.16) it finally works:

Including a fragment using JSTL's c:import or jsp:include that is
invoked by a Struts Action! Prior, it failed, when the importing JSP was
also invoked by a Struts action; thus having two Struts' Action calls in
one physical request.

Now this finally works w/ the same JSTL 1.1 and Struts JARs! Thanks
Apache!

BTW.: or does someone know if this shall work even w/ prior versions? I
once found a bug report regarding that special problem; but culd not
remember if this was for Struts, JSTL or Tomcat.

Hi,

I know your question has been answered, but I'd
recommend you get the examples .war file for your
distribution of JSTL.

Here's the URL for JSTL 1.0

http://apache.ntcity.co.uk/jakarta/taglibs/standard-1.0/

It gives neat little examples of all the JSTL tags
and how to use them.

It may help going forward.

Re: FMT question

[Dima Gutzeit]

Here is the summary of the behaviour on my side :

On the first page of the application everything works great. Problem starts
when I  to another JSP page in the application.

On this new page , the application totaly "forget" what locale has been set
nad takes the settings from web.xml

Both pages are in the same application , sharing the same session.

Anyone has ideas ?

RE: Tag to Unescape an HTML String?

[Daniel Lipofsky]

I didn't try it myself, but the docs say that 
encodes using URLEncoder.encode() - so there should
not be any "&" style encoding and URLDecoder.decode
should work fine.  But I don't speak from experience.

Re: FMT question

It seems to work for me. Here's my setup:

/WEB-INF/classes/Messages.properties (msg=root)
/WEB-INF/classes/Messages_en_US.properties (msg=en_US)
/WEB-INF/classes/Messages_fr.properties.properties (msg=fr)

web.xml:


  javax.servlet.jsp.jstl.fmt.localizationContext
  Messages


If my JSP just has this:

msg: 

It produces:

msg: root

If I change the JSP to:


msg: 

It produces:

msg: fr

RE: Tag to Unescape an HTML String?

[Henri Yandell]

Commons Lang 2.0+ contains a StringEscapeUtils which has an escapeHtml and
unescapeHtml that handle the &'s etc. I can look to adding these to the
String Taglib as it depends on Lang anyway, is easy to code and is in need
of an update to fit Lang 2.0.

Still waiting for JSP 2.0 to be a bit more out there before trying to
decide what future String Taglib really has for me.

RE: Tag to Unescape an HTML String?

[Martin van Dijken]

Hey Jim and Dan,

The URLDecoder.decode method decodes a URLEncoding. This is the encoding
browsers do when you type for instance a spacechar in the location bar,
the browser replaces it with %20. This is definitely not the same thing
as HTML encoding in which you would replace the char & by &.
URLDecoding is definitely not a solution for your current issue. I've
never found a generic solution, but that is not to say there isn't one.

Concerning your page layout issues, I'd definitely advise you to take a
look at Tiles. It works very well with struts as a plugin, but as I
understand it can function standalone as well. 

http://jakarta.apache.org/struts/userGuide/dev_tiles.html

Good luck!
