Re: Resource Bundle Problem (sometimes)
I tried both the super.pageContext and just pageContext, but neither works.
Is there any other way to do this? (In the examples people use other classes
than ExpressionEvaluatorManager so maybe I should use another one?). What I
cannot understand is why the same tag works fine on other pages, but the
moment I use it inside another tag the setter method sets a null/empty. I
have many other custom tags though that work just fine - just this one
(driving me crazy).
Shall I post the source?

Hi there,
I have my own tag (extending BodyTagSupport) in which I do the
following:
code
ResourceBundle resources = ResourceBundle.getBundle(application);
out.print(resources.getString(key));
/code
This works great ... most of the time. However, the moment I put this
tag
into another tag that I wrote (a Data Table Tag - extending
LoopTagSupport)
I get the following exception(below). For some reason it seems to find
the
application.properties resource file when my tag is on its own

Re: Resource Bundle Problem (sometimes)
I solved the problem!!! Because the tag was used inside another tag (that
extends LoopTagSupport) this caused the expression (or rather the setter
method) to resolve to spaces for the very first iteration of the loop. As a
result the tag was trying to look up empty spaces in the resource bundle and
failed. I now trim and test for this in the tag so it just prints an empty
space when that happens and then all the other iterations worked
successfully.
Quite a stupid mistake that took a long time to resolve... Thanks for the
input and help!

RE: How to print an int with a c:out tag?
Thanks guys, I tried that and got a new error (below). I will probably just go the scriptlet route for now as maybe I have an old or incorrect JAR somewhere. Can any one tell me where the TagLib for FN is? What I did: 1. Changed web-app ... as per example. 2. Included FN taglib in my web.xml file as I do with the other ones I use: taglib taglib-uri/tags/fn/taglib-uri taglib-locationhttp://java.sun.com/jsp/jstl/functions/taglib-location /taglib taglib taglib-uri/tags/jstl-core/taglib-uri taglib-location/WEB-INF/c.tld/taglib-location /taglib Then I get File http://java.sun.com/jsp/jstl/functions; not found, OR, If I don't import the taglib in my web.xml file and just try to use it, I get: The attribute prefix fn does not correspond to any imported tag library Thanks again for you patience, you've been a great help and I've learned quite a bit.

My next guess was going to be one thing mentioned on the page Murray links to below. Regardless of whether you are using Tomcat 5, JSTL 1.1 and JSP 2.0... if your web.xml doesn't say it's a servlet 2.4 app it will revert to Servlet 2.3/JSP 1.2 (and trying to use JSTL 1.1 with JSP 1.2 probably introduces many other problems...). As the page says, make sure your webapp element starts like this: web-app xmlns=http://java.sun.com/xml/ns/j2ee; xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance; xsi:schemaLocation=http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd; version=2.4 Otherwise the container will assume the servlet 2.3 spec and EL will not be allowed outside of JSTL (1.0) tags. The fn:length() function I originally mentioned is part of JSTL 1.1 anyway so it sounds like you just need to make sure everything is configured for the current specs and you should be good. Hope that will fix it up for you. -Christian Murray Steele wrote: Perhaps this page might provide the solution? http://www.oreillynet.com/cs/user/view/cs_msg/32931 Wrong taglib uri's or wrong webapp specification in your web.xml.

Hi Marius,
Check out the fn:length() function, this is what you are looking for.
size() is a method and you cannot call methods directly from JSTL (only
getters and setters), but the fn taglib provides a function for length
of Collections and strings. See the JSTL 1.1 documentation for more
information, but basically fn:length() is what you are looking for:
c:out value=${fn:length(myList)}/
Hope this helps.

RE: How to print an int with a c:out tag?
My requirement is really a bit different. I have an expression, which
returns a List, the size of which I would like to display. I.e. I have
${myController.activitiesForResource}, which returns a list.
If I try c:out
value=${fn:length(${myController.activitiesForResource})}/ I get an error
saying EL expressions are not supported. Any ideas?

RE: How to print an int with a c:out tag?
You know your stuff hey :)
I believe I do use Tomcat 5 (running inside JBoss 3.2) and as a result have
their JSTL (looks like 1.1) and JSP-2.0.jar. Where do I find or can I check
if I have the TLD for the functions library (so I can include it if
missing)? At the moment I am including the TLD's in my WAR project and
specify them in the web.xml file.
Thanks again.

I suspect that you are using either Tomcat 4.1.x and / or Standard 1.0x
for your JSTL. EL functions are part of the JSTL 1.1 spec (JSP 2.0)
and aren't supported on Tomcat 4.1.x or Standard 1.0x (JSP 1.2 and JSTL
1.0 respectively). If you want to use the fn:length you need to use
JSTL 1.1 and hence Standard 1.1 and / or Tomcat 5.x. (I think those
versions are correct, someone correct me if I'm wrong).
If you cant change the version of Tomcat / JSTL you use:
1. You could alter your myController.getOpenActivitiesForResource
method to return a class that extends list to provide a getSize() (and
hence your original c:out value=${myList.size}/ would work.
2. Find some other Tag lib that lets you output list sizes.
(unstandard from the sandbox does this)
3. Just use a scriptlet %= ((MyControllerClass)
pageContext.findAttribute(myController)).getOpenActivitiesForResource(
).size() %.

Dynamically adding components to pages
Hi there, Hope someone can help me. I have a requirement where my system needs to prompt users for certain information at certain times in a process. To do this I need to be able to add components to a page at run time based on a user's permissions. E.g. if the user is supposed to specify a date for the process to continue, I need to provide a calendar control; and if the user needs to enter a name, then provide a textbox. I have developed my own custom tags that I would want to use but I have the following questions: 1. How do I reuse my components in such an environment? I suppose I would need to provide a StringBuffer or something to my component to write to (how?) and then call the doStartTag(), etc. methods manually? 2. How do I implement this in the JSP, seeing as the html/tags would have to be inserted at a certain stage. Has anyone done this before or can you give me any pointers? Much appreciated.

Thanks. Are you referring to http://www.displaytag.org,

In the end I just did the following: Created 4 tags as below, where the
tree tag writes out the containing HTML, the nodeIcon allows the JSP
developer to define icons to use depending on the type of tree node and then
the iterator just iterated (so no need to write out HTML). The
displayNode tag painted the node depending on its content and context.
tree:tree name=myTree traverserAction=/tree/tree.do targetFrame=main
defaultNodeClass=defaultNode
selectedNodeClass=selectedNode
cellpadding=1 cellspacing=0 border=1
width=100% styleClass=myTable
tree:nodeIcon type=String

tree:nodeIcon type=Integer

Check out the display tag. Google should tell you where to get it. You
essentially just give it a collection and it writes all of the html to
display it in a table.

Hi Felipe,
Thanks for the response.
I had a look, but my challenge is that I would like the iterating tag to
write out HTML as well, not just iterate through the collection. I.e. the
tag handler should create the surrounding table tags and when it iterates
over the elements, they will create the TR and TD elements if required.
I don't see an example or where I can find an iterating tag with like a
doStartTag() and doEndTag() method that works to do this. I must be missing
something...

Creating a custom Iterate Tag
Hi there,
I need some guidance with creating a custom iterate tag (literally like the
standard IterateTag, but where I can control what happens). I tried to find
good examples or tutorials on how to do this, but couldn't find anything
good so please advise if you know of anywhere good to look that is up to
date.
Previously I developed a class called TreeTraverserTag which extends
TagSupport. It takes the following attributes name, traverser, etc. and then
paints a pretty Windows like tree with multiple level nodes in the browser
based on the tree structure. Now however I want to change this tag to
instead iterate over the nodes and write HTML based on each nodes properties
(like a different colour or icon based on type, etc.).
Please advise which class to I need to extend or interface I need to
implement so I can control the next(), hasNext(), etc. methods (as the tree
is hierarchical with nodes that can expand or collapse, therefore not a
standard collection or Array) as well as being able to write out the HTML
for each iteration. Examples or tutorials would be welcome. I tried a couple
of classes and interfaces but ran into problems due to a lack of experience.
Things like the doAfterBody method was never called , or it went into a
loop, etc.
At the moment my tag looks like this:
t:tree name=myTree traverser=${treeTraverser}
defaultNodeClass=defaultNode
defaultNodeImgageUrl=/folder.gif
selectedNodeClass=selectedNode
selectedNodeImgageUrl=/folder2.gifcellpadding=1
cellspacing=0 border=1 width=100%
styleClass=myTable
/t:tree
Ultimately I want to do something like this (if it is possible):
t:tree name=myTree var=node traverser=${treeTraverser}
icon name=blue src=blue.gif/
icon name=red src=red.gif/
c:if test=${node instanceOf Document}
DISPLAY RED
/c:if
c:if test=${node instanceOf Resource}
DISPLAY BLUE
/c:if
/t:tree
Much appreciated.
Kind regards,
