error on starting Tomcat

[asd]

hi,

I am trying to create a custom tag but get exception when tomcat is
started.

my tld file(dbdata.tld) file is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE taglib
PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.2//EN"
"http://java.sun.com/dtd/web-jsptaglibrary_1_2.dtd">
<taglib>
<tlib-version>1.2</tlib-version>
<jsp-version>1.3</jsp-version>
<short-name>exp</short-name>
<!--info>Simple db example</info-->

<tag>
<name>dbdata</name>
<tag-class>tagext.DBData</tag-class>
<body-content>JSP</body-content>
<!--info>displays data</info-->
</tag>
</taglib>

and web.xml is as below:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
"http://java.sun.com/dtd/web-app_2_2.dtd">

</servlet>
<servlet-mapping>

</servlet-mapping>

<servlet-mapping>

</resource-ref>

<taglib>
<taglib-uri>/dbdata</taglib-uri>
<taglib-location>/WEB_INF/tlds/dbdata.tld</taglib-location>
</taglib>

This is the exception that is seen in the Tomcat logs for my
application:

Do I have to do any settings in server.xml for custom tags?
Thanks in advance for any help....

hi,

I am trying to create a custom tag but get exception when tomcat is
started.

----- Root Cause -----
java.lang.IllegalArgumentException: Invalid TLD resource path
/WEB_INF/tlds/dbdata.tld

Probably WEB_INF should actually be WEB-INF (subtle error)

<taglib>
<taglib-uri>/dbdata</taglib-uri>
<taglib-location>/WEB-INF/tlds/dbdata.tld</taglib-location>
</taglib>

That's unless your installation of tomcat is different and you actually
do have a WEB_INF directory.

No
