Have a check, whether you have all TLD and LIB files into the folder and set to the classPath too.

You have a caracter no valid. Parse the XML web.xml and struts-config.xml.

I had this problem before. Replace <html:form action = "lookup" name = "lookupForm" type = "ch03.lookupForm"> with <html:form action = "lookup"> in the index.jsp and you should be fine.

Similar problem here.. Looking for some help.

I have the files set up as follows:

..\webapps\ch03app\index.html
..\webapps\ch03app\quote.html
..\webapps\ch03app\WEB-INF\web.xml
..\webapps\ch03app\WEB-INF\struts-config.xml
..\webapps\ch03app\WEB-INF\classes\ch3\LookupAction.class
..\webapps\ch03app\WEB-INF\classes\ch3\LookupForm.class
..\webapps\ch03app\WEB-INF\src\LookupAction.java
..\webapps\ch03app\WEB-INF\src\LookupForm.java

I added c:...\webapps\ch03app\WEB-INF\classes to my classpath.

Both the LookupAction and the Lookup form are packaged as:

package ch3;

I compiled the code and put the class files into ..
..\WEB-INF\classes\ch3
I modified the code to remove the attributes from the form as described in the example above.

<html:form action="Lookup">

The struts-config.xml file contains the following:

<?xml version="1.0" encoding="ISO-8859-1" ?>

<!DOCTYPE struts-config PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN"
    "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">

<struts-config>

    <form-beans>
        <form-bean name="lookupForm"
            type="ch3.LookupForm"/>
       </form-beans>

    <action-mappings>
        <action
            path="/Lookup"
            type="ch3.LookupAction"
            name="lookupForm"
            input="/index.jsp">
            <forward name="success" path="/quote.jsp"/>
            <forward name="failure" path="/index.jsp"/>
        </action>
    </action-mappings>

</struts-config>

This handled the attribute name being invalid, however I now have the following error:

Exception report

The server encountered an internal error () that prevented it from fulfilling this request.

javax.servlet.ServletException: Exception creating bean of class ch3.LookupForm: java.lang.ClassNotFoundException: ch3.LookupForm
    at org.apache.jasper.runtime.PageContextImpl.handlePa geException(PageContextImpl.java:495)
    at org.apache.jsp.index_jsp._jspService(index_jsp.jav a:101)
    at org.apache.jasper.runtime.HttpJspBase.service(Http JspBase.java:92)

Any suggestions?
