org.apache.jasper.JasperException: Attribute action invalid for tag link according to TLD

[Deepak Kumar Jena]

Getting JasperException as Attribute action invalid for tag link according to TLD.
Developed an application for DispatchAction with struts.jar (Struts 1.2 distribution), struts-core-1.3.10.jar and struts-extras-1.3.10.jar in the classpath and in the lib folder of the application in server with the TLDs in WEB-INF.

Exception is due to these statements:
<html:link action="/add">Add</html:link><br />
<html:link action="/modify">Modify</html:link><br />
<html:link action="/delete">Delete</html:link>

Thanks in advance.
