DeclareControl taglib in jsp

Dear all,
I am trying to use "declareControl" in jsp in order to use a control method.
But I found that it can't declare the control which I stored in a seperate
Control Project. Is that taglib restricted us to declare control within same
project? Thx a lot.
<netui-data:declareControl type="dbControls.ProductsDBControl"
controlId="productsDBControl"/>

Karen--
I'd suggest upgrading to SP2. I tried this with a custom control
(JCS) and with a simple DB control which were both visible and invokable
with that tag from a JSP.
Try upgrading and let me know if you see the same problem.
Hope that helps.

Well, I am using WLW 8.1 GA. I have built the Control Project before runing
my jsp. The control can imported in my jsp successfully since I can read all
methods in my Data Palette. But I don't know why error occur everytime when
I run the jsp. It seems locating the control in same web application.
Thx.

Hi; a couple of questions...
Are you using WLW 8.1 GA or SP2?
Are you building the entire application before trying to run the JSP
(Build -> Build Application)? The control project isn't necessarily
built if you just run the JSP itself.

Which oc4j version are you using? You can get the version by
java -jar oc4j.jar -version

Hi Riaz,
You can use same code in JSP
Java Code
import java.util.*;
class TestHashMap
public static void main(String args[])
HashMap hm=new HashMap();
//store some Objects.
hm.put("Rajib Sarma","100");
//duplicate keys are not allowed.
hm.put("Rajib Sarma","200");//The value "100" is replaced by "200".
hm.put("Sazid Ahmed","200");
//Display the contents of the HashMap
System.out.println("Displaying all the keys/values.\r\n");
System.out.println("Key\t\tValue\r\n");
//get all the keys
Collection c=hm.keySet();
//obtain an Iterator
Iterator i=c.iterator();
while(i.hasNext())
//obtain a key
Object key=i.next();
//obtain the value of the key
Object value=hm.get(key);
System.out.println(key +"\t" + value);
}//while ends
}//main ends
}

Custom taglibs w/ JSP features

Hello Together,
I am currently facing a little problem:
I use custom taglibs for rendering certain web elements (lets say widgets etc.). The reason is greater reusability and full integration into the runtime. However, what do you recommend on how to render such components?
As far as i know, there are only two solutions:
- embedding markup (e.g. XHTML, XML...) into the tag class (not so good, especially when large chunks of markup)
- reading from markup templates located on the file system and populating them w/ data (slow?).
What do you use for custom taglibs that are to render markup contents (thus, no flow taglibs)?
I know that i can fallback to pure JSPs, but there is no elegant way calling them with parameters. The reason is that i have "abstract control classes" with some properties. According to these properties, my taglib renders the control. When doing this with a JSP fragment, there is no "cool" way:
the class proto: an GUI class with properties
- id
- caption
- state
- etc.
-- taglib example --
<some:guiElement obj="${controls.current}" method="xml" />
This taglib can query all properties by the obj reference and render.
-- JSP equivalent w/ JSTL call --
<c:import url="/base/guiElement.jsp?id=${controls.current.id}&caption=${controls.current.caption}[...]" />
This is bad design, and all params have to be passed seperately (or not?).
You see, Taglibs are quite more handy to use, as you know. But i am missing JSP features in taglibs, such as how to do an <c:import /> from within an taglib etc.
Another thing in mind is themeability. One can use a copy of the JSP fragment and modify its visual appearance, but w/ taglibs, that is more harder (except when using markup templates).
Does anyone knoe how to marry JSP featires into custom taglibs?
Sorry for that long posting :-)
Greetings, Timo

Hello,
Just an answer to myself and anyone who is interested:
The solution to my problem is migrating to JSP 2.0 where you can use tag template files.
Thus, if possible, upgrading to JSP 2.0 + Servlet 2.4 does the job.
Greetings, Timo

Taglib and JSP problem

Hi!
I cannot determine why I'm getting the following error:
I've installed Apache Tomcat/4.0.6
"PARSE error at line 6 column 19
org.xml.sax.SAXParseException: Element type "taglib" must be declared."
Can you tell why the parser does not recognize it?
Appreciate any help.

this is a wild guess, but make sure the taglib text you added to your web.xml doens't contain funky characters you may have copied from some web page. i.e. retype it by hand if you copied it.
If that isn't it.. sorry i don't see a problem.

How to use tags from taglib in jsp

i am using tomcat. I don't know where the taglibrary is stored i.e in which folder and how can i access that library and use it in the jsp pages.

Refer to

Taglib and jsp pages question

Hi, I just recently got tag libraries to work and I am wanting to send a dynamic attribute that has a value which is stored in the session. The problem is that I believe that the tag library is processed before the actual jsp code is, and therefore I get something like
<%= someObj.getValue() %> instead of the actual value. Has anyone else encountered this issue and if so could you please recommend some solution(s)?
Here is how I call the taglibg:
<countytaglib:countyList state="TN" selectedCounty="<%= county %>" />
The value ends up being '<%= county %>' instead of the actual value.
Any help is appreciated. Thank you all in advance!

The required is only if the attribute is required.
For your question's answer the rtexprvalue should only be true.
in the TLD file for the TAG, for every attribute whose
value can be evaluated by the JSP scriptlet put as
follows:
<attribute>
<name>attribute_name</name>
<required>true</required>
<rtexprvalue>true</rtexprvalue>
</attribute>rtexpvalue should be specified to true in case for the
attribute
name you would like something like
<%= user.getFirstName() %>Hope that helps.

Jsp taglibs and jsp commands...

Another question about taglibs...
If I want to use the body in a tag together with a class which is used in the tag code.
For example I want to do the following:
<foo:listStudents>
<%= student.fname %> <%= student.lname %> <%= student.id %>
</foo:listStudents>
Do I have to use the TagExtraInfo or? The class Student (student) is ofcourse declared and used in the tag.

I am also on the lookout for this. i have posted many times but no one has answered my question till now. if you get to know the answer do inform me at

Make Taglib with JSP

Dear all,
I didn't work on JSP with JSTL. If anyone can help me in this regard for making a simple JSP page with JSTL, it will be highly appreciable.
I am working on Tomcat 5.0.
Thanks for ur time

What do you mean 'help' ?
I would advice you to make a start by reading up the documentation here - http://java.sun.com/j2ee/1.4/docs/tutorial/doc/JSTL.html#wp74644, to download the tag libraries here - http://java.sun.com/products/jsp/jstl/index.jsp (there's also a documentation)
and start putting pages using jstl.
When you are stuck up, come here by all means, post your problems and people would only be too happy to aid you. A generic shout for 'help' like the one in your post wouldnt get much response.
cheers,
ram.

Custom TagLib & JSP Helpers

I've written a custom tag library for some advanced UI components (tabbedpane, toolbar, tree, etc.) that I've been distributing for free as a .jar file with the associated .tld file. So far, so good.
Now I want to write some more advanced tags (i.e. a DateSelection and Calculator tag) that will require some helper JSP files (and possibly images) to render the actual calendar and calculator.
My plan is to have the tag generate a textfield with a hyerplink image to it's right. When clicked the image would load the helper JSP file in a new window. The user would do his thing and when done, the JSP would reload the parent window so the textfield could grab the result from the request and display it.
My question is how to package this. I would like to keep this thing as a single self contained .jar file that could be easily placed in the WEB-INF directory of a user's webapp and VIOLA, it's done.
Can I reference a .JSP (& | images) stored in this jar file or will the user have to be responsible for placing the JSP(s) (and the hyperlink images) within their context path? This would add some possible support issues (you know what I mean) and being a freeware package I'd like to avoid that at all costs.
You guys have been tremendous help so far. Thanks.

how will mailing the jar help ?
I dont think you can include it all in the jarfile. Best thing is to make an entire war file with the developed taglib and jsp's.
The user then should deploy the war file and ervything should work.

Custom taglib and inexplicable jsp compilation issue

Can someone explain what could possibly be happening here? I have been working on this for two days to no avail.
With the following configuration, my jsp behaves as I expect it to on Tomcat, but fails to compile both for Jetty and the Maven2 jspc plugin
deepfij.tld
<taglib version="2.0" xmlns="http://java.sun.com/xml/ns/j2ee [3]" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee web-jsptaglibrary_2_0.xsd">
<tlib-version>1.0</tlib-version>
<short-name>deepfij</short-name>
<uri>com.fijimf.deepfij</uri>
<tag>
<name>menuItem</name>
<tag-class>com.fijimf.deepfij.web.tag.MenuItemTag</tag-class>
<body-content>scriptless</body-content>
<attribute>
<name>item</name>
<required>false</required>
<rtexprvalue>true</rtexprvalue>
</attribute>
</tag>
</taglib>
menubar.jsp
<%@ taglib prefix="df" uri="/WEB-INF/tlds/deepfij.tld"%>
<c:forEach var="page" items="${menuRootPages}">
<df:menuItem item="${page}" />
</c:forEach>
MenuItemTag.java
package com.fijimf.deepfij.web.tag;
.With the error: com.fijimf.deepfij.web.tag cannot be resolved to a type.
BUT*, if I move MenuItemTag into the package com.fijimf.web, and correspondingly change the .tld, everything works as expected.
Is this a bug, or is there a constraint in taglib packages I don't know about?
Any guidance would be great, because I'd like to put classes where I want them.

This is most likely a bug on the server. The JSP formatted Tag Files usually have a .tag extension on them ( [see tutorial|http://java.sun.com/javaee/5/docs/tutorial/doc/bnama.html] ). The server is probably looking at yyy.xxx.tag and trying to use it as if it was a Tag File named xxx.tag, rather than a package.

What is the use of %@ taglib uri="taglib" prefix="hbj" % in jsp?

what is the use of
<%@ taglib uri="taglib" prefix="hbj" %>
in jsp?
The portal Content works fine even without that.
Any specific reasons?

Hello Hanif,
This is the we declare taglibs in JSP files. Check this for definition:
http://java.sun.com/products/jsp/tutorial/TagLibraries5.html#61992
After declaring this taglib <%@ taglib uri="taglib" prefix="<b>hbj</b>" %>
, you can use all HTMLB classes as tags in JSP.
I am not sure in which JSP you mean that every thing works fine with out this taglib!! But if you remove this taglib, then you cannot use HTMLB in this JSP.
