Problem while running JSP Custom Tag

[Gaurav Chhabras]

Hello to all

I am new to JSP Custom Tags.
I am using Tomcat 5.0 and trying to run JSP Custom Tags.Firstly please tell me that is anything else is also required to use JSP Custom Tags.

Now i have made 3 files -:

1) ExampleTag.class in /webapps/root/WEB-INF/classes/coreservlets/tags/

2) csajsp-taglib.tld in /webapps/root/WEB-INF/

3) ram.jsp in /webapps/root/

and in web.xml , which is in /webapps/root/WEB-INF/web.xml i have make changes and write there -:

<taglib>
<taglib-uri>csajsp-taglib.tld</taglib-uri>
<taglib-location>csajsp-taglib.tld</taglib-location>
</taglib>


and in csajsp-taglib.tld i have written -:

<taglib>
<!-- after this the default space is
"http://java.sun.com/j2ee/dtds/jsptaglibrary_1_2.dtd"
-->
<tlibversion>1.0</tlibversion>
<jspversion>1.1</jspversion>
<shortname>csajsp</shortname>
<urn></urn>
<info>
A tag library from Core Servlets and JavaServer Pages,
http://www.coreservlets.com/.
</info>

<tag>
<name>example</name>
<tagclass>coreservlets.tags.ExampleTag</tagclass>
<info>Simplest example: inserts one line of output</info>
<bodycontent>EMPTY</bodycontent>
</tag>

</taglib>


Please check my paths and version which i have written in csajsp-taglib.tld, wheather they are correct or not, if wrong then please rectify them.

now when i am running the ram.jsp error is coming -:

Do you have this in your tld?

<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.1//EN"
"http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd">

thanks for response

Sir i have written this is my TLD file.
The error is coming -:

org.apache.jasper.JasperException: Unable to initialize TldLocationsCache: XML parsing error on file /WEB-INF/csajsp-taglib.tld: (line 3, col 13)

i am not able to understand that what problem it might be.

For custom tags should we have to download TAG LIBRARIES from JAKARTA, as i have not downloaded them.
