HashMaps and Hashtables are unordered collections. The order in which you
add elements to them does not make any difference at all. If you need to
preserve that order, you may want to take a look at the SequencedHashMap
class in the Jakarta Commons Collections package.

How to maintain the selection items in the Select using the jakarta.apache.org input tag library

[Kimberly Clary]

I want to have the items in my Select list showing in a certain order.
I've looked over both the html and jsp examples that were provided when I
downloaded the tag lib but they only contain the basics.

I enter the following in my jsp -

  
BACCode:(none or allreturns
all)
  
  
<%
java.util.HashMap b = new java.util.HashMap();
b.put("id", "bac");
b.put("multiple", null);
b.put("size", "6");

java.util.Hashtable bo = new java.util.Hashtable();
bo.put("CSP", "1");
bo.put("FAP", "2");
bo.put("FRU", "3");
bo.put("OPT", "4");
bo.put("PPN", "5");
bo.put("Paper", "6");
%>

  

but the data doesn't display in this order.
It's showing up in the order of -

FAP
OPT
PPN
Paper
CSP
FRU

I think the code should be using the getKey method for building this
selection list if we want to maintain the order.
Can someone help me?
Thanks - Kim

Re: How to use c:url with c:import?

[K.C. Baltz]

Tried that.  It just looks for my files in the ROOT context, rather than 
the context specified in the URL.  I also tried context="", but that 
produced an exception.

Re: How to use c:url with c:import?

[Brice Ruth]

The session-id information that c:import removes, is not the web module 
bit that gets prefixed by c:url, or your extension of html:rewrite. 
Incidentally, html:rewrite is meant to allow module-relative referencing 
of resources (page="/resource-name") ... I'm guessing this is a bit 
different than c:url's advertised purpose. Have you considered extending 
c:url instead of html:rewrite? If you don't want the module-prefix 
added, you could also extend the behaviour of  which wouldn't prepend the module-name, but 
would still be able to do the custom stuff you're apparently needing to do.

Incidentally, if all you need to do is append a few parameters, setting 
up a hash map using jsp:useBean and passing that map to a plain-vanilla 
html:rewrite, might do the trick for you.

Does import work if you specify `url="/text.html"` explicitly?

You might try appending an "http://" to the beginning of 
textURL and see if c:import is happier with that ...

Re: Going nuts...

[Martin Cooper]

Well, for one thing, it looks like you've got your base classes the wrong
way around. You have the body-less tag extending BodyTagSupport, and the
body-ed tag extending TagSupport.

For another, your TLD has values for  such as 'no' and 'tue'.

I don't know if either of those is the cause of your problem, but they
certainly won't help. ;-)

RE: unable to find value

[Morrow, Steve D.]

Yeah, I'm familiar with the map notation. Unfortunately, this is a List. All
the other values for this object are printing fine, just not the 'id'. I've
chalked this one up as a loss and am simply using another method (getID(),
as opposed to getId())to get the value.

The sunspots must still be in full effect. LOL.

RE: unable to find value

[SThongvanh]

Hey Steve-
If you didn't figure it out here's another suggestion.  If you are using a
Map you might need to use the name="myBean.value" notation.  It's a little
different than using List in iteration.

how I write it.

AW: Going nuts...

[Moritz Bayer]

Hi james & everyone else,

I looked into it and found the following line in the code:

   if (pageContext != null) pageContext.handlePageException(t);

I made some research and all I could find was, that this might happen if I use an 
servlet.jar version, that contains the classes of jsp1.1. I looked into the Manifest 
file of the servlet.jar I use, and, if I get it right, it uses jsp1.2. 
Some more information about my system and tomcat setup that might help give me a hint:

- Apache Tomcat 4.1.27
- J2SDK 1.4.1_01

That's all I can give you so far, would be very thankful for anything that helps,
Moritz

bah. sorry - accidentally hit the send button before i was finished.  take
two:

i don't have time to go through all the code at the moment, but take a look at this 
line in your stack trace:

at
org.apache.jsp.mitglieder_l_jsp._jspService(mitglieder_l_jsp.java:252)

it tells you the line in the generated servlet that failed.  you can find that JSP in 
(if you're using tomcat) tomcat's work directory.  if not, most other containers have 
something similar.  open the JSP up and look at line 252 -- this almost always clues 
me into what is going on.

good luck!

RE: Going nuts...

[JFarley]

bah. sorry - accidentally hit the send button before i was finished.  take
two:

i don't have time to go through all the code at the moment, but take a look
at this line in your stack trace:

at
org.apache.jsp.mitglieder_l_jsp._jspService(mitglieder_l_jsp.java:252)

it tells you the line in the generated servlet that failed.  you can find
that JSP in (if you're using tomcat) tomcat's work directory.  if not, most
other containers have something similar.  open the JSP up and look at line
252 -- this almost always clues me into what is going on.

good luck!

Going nuts...

[Moritz Bayer]

hello list, 
 
I really donm't know why I always have to get these strange messages, but once again, 
I have an Exception I really don't understand. This is killing my time and my 
motivation. Hope someone can help me out of this situation!
I want to nest a tag within another tag, and my jsp-code looks like this:
 
...
<%@ taglib uri="/WEB-INF/classes/tlds/test.tld" prefix="test" %>


 
 

 
-
The tags are defined as followed:
