the value of <%@taglib uri="" %>?

[Poonam Agarwal]

The tag library descriptor shown in the exhibit has been kept in /WEB-INF/mytlds/tld1.tld folder of the webapplication. What should be inserted at line 6 so that line 7 will work as expected?

5. ...
6. &lt;&lt;INSERT CODE HERE &gt;&gt;
7. &lt;mytags:tag1 /&gt;


Assume that the application can be accessed through http://localhost/myapp

 <?xml version="1.0" encoding="ISO-8859-1"?>
<taglib 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/j2eeweb-jsptaglibrary_2_4.xsd"
	version="2.0">
  <tlib-version>1.0</tlib-version>
  <short-name>mytags</short-name>
  <uri>http://abc.com/tld/mytaglib</uri>
  <tag>
    <name>tag1</name>
    <tag-class>com.abc.Tag1</tag-class>
    <body-content>scriptless</bodycontent>
  </tag>
</taglib>   

1. &lt;% taglib uri="/WEB-INF/mytlds/tld1.tld" %&gt;
2. &lt;% taglib prefix="mytags" uri="/WEB-INF/mytlds/tld1.tld" %&gt;
3. &lt;% taglib prefix="mytags" uri="http://abt.com/tld/mytaglib"; %&gt;
4. &lt;% taglib prefix="mytags" uri="http://localhost/myapp/WEB-INF/mytlds/tld1.tld"; %&gt;

the 2nd option is true. Why?? I thought the value of &lt;uri&gt;&lt;/uri&gt; tag in the TLD is specified in the &lt;%@taglib uri=""%&gt; directive. I know that we can specify the direct path to the TLD file as a value of uri attribute. I got confused. Please help

Please correct me if I am wrong.

[Ankit Garg]

First of all Poonam can you please QuoteYourSources.

I couldn't understand which option is given as true- 2 or 3 or both. I think all the options are wrong. None of them is a taglib directive. And just take a look into this page to be more clear about the use.

[Poonam Agarwal]

According to Enthuware option 2 is correct. I don't know why?

[ankit kumar]

according to me option 3 should be correct because
<uri> tag value should be match with the <%@ taglib uri="" >
please correct me if I m wrong .

[Ankit Garg]

Well I did some research and this tutorial helped me a lot. Option 3 is not correct. There are two ways you can use the uri attribute of the taglib directive.

1. You define a .tld file and then include its reference in the web.xml file. In that case you can use the uri which is given in the .tld file in the taglib directive.

2. You define a .tld file and then use the path to the .tld file in the uri attribute of the taglib directive.

So option 2 is logically correct but as I said earlier too, none of them is a taglib directive so all are wrong

You are now SCWCD cleared then what to worry . Anyways it is good to have the enthusiasm to learn. There are two ways of using the uri attribute of the taglib directive.

1. I declare the tld1.tld file in the /WEB-INF/mytlds/tld1.tld folder and then put this code in my web.xml

<taglib>
     <taglib-uri>http://abt.com/tld/mytaglib</taglib-uri>
     <taglib-location>WEB-INF/mytlds/tld1.tld</taglib-location>
</taglib>

Then in my JSP page I need to write this

<% taglib prefix="mytags" uri="http://abt.com/tld/mytaglib" %>

2. The other way is that I add the tld1.tld file in the /WEB-INF/mytlds/tld1.tld folder and use this in my JSP page

<% taglib prefix="mytags" uri="/WEB-INF/mytlds/tld1.tld" %>

[Poonam Agarwal]

Thanks Ankit, to make it clear.

If you read the post carefully I have also insist on the same point, might not good with words while posting.
anyways to confirm it once again for me.

Thanks again

[Frits Walraven]

Have a look here: dtd

if uri tag is not mandatory. what i would put in the jsp

Just look back in this thread and you will see that you can use a direct reference to the tld file:

<% taglib prefix="mytags" uri="/WEB-INF/mytlds/tld1.tld" %>
