Hi guys..

This is my first post in this site.

I am deploying my first struts application.
I got held up at an exception.

I am including the details here:

my root directory is C:\jakarta-tomcat-4.1.30
I created a directory by name "struts" in webapps.
(C:\jakarta-tomcat-4.1.30\webapps\struts)
I created the directory "web-inf" and index.jsp is my first view.

C:\jakarta-tomcat-4.1.30\webapps\struts\WEB-INF.
C:\jakarta-tomcat-4.1.30\webapps\struts\index.jsp

I copied all the jar files from C:\jakarta-struts-1.2.4\lib to
C:\jakarta-tomcat-4.1.30\webapps\struts\WEB-INF\lib\

__________________________________________________________________________
index.jsp:

<%@ page language="java" %>
<%@ taglib
uri="/WEB-INF/struts-html.tld"
prefix="html" %>
<html>
<head>
<title> First Struts Application</title>

</tr>
<tr>
<td colspan="2" align="center">
<html:submit />
</td>
</tr>
</table>
</html:form>

</body>
</html>
_______________________________________________________________________

I included the following in web.xml:
C:\jakarta-tomcat-4.1.30\webapps\struts\WEB-INF\web.xml


<taglib>
<taglib-uri>
/WEB-INF/struts-html.tld
</taglib-uri>
<taglib-location>
/WEB-INF/struts-html.tld
</taglib-location>
</taglib>

I copied struts-html.tld from C:\jakarta-struts-1.2.4\lib to
C:\jakarta-tomcat-4.1.30\webapps\struts\WEB-INF\

ActionForm and Action :
C:\jakarta-tomcat-4.1.30\webapps\struts\WEB-INF\classes\first
LookupAction.java
(Package first contains 2 classes :LookupAction and LookupForm)
__________________________________________________________________________
package first;

public class LookupAction extends Action
{

protected Double getQuote(String symbol)
{

if(symbol.equalsIgnoreCase("SUNW"))
{

return null;
}

public ActionForward execute(ActionMapping mapping,

{
Double price=null;
String target=new String("success");

if(form!=null)
{
LookupForm lookupForm=(LookupForm)form;
String symbol=lookupForm.getSymbol();
price=getQuote(symbol);
}

if(price==null)
{
target=new String("failure");
}
else
{
request.setAttribute("PRICE",price);
}

return (mapping.findForward(target));
}

}

class LookupForm extends ActionForm

public void setSymbol(String symbol)
{
this.symbol=symbol;
}

public void reset(ActionMapping mapping,HttpServletRequest request)
{
this.symbol=null;
}

}
___________________________________________________________________________
I compiled the above java file. The corresponding class files are in
C:\jakarta-tomcat-4.1.30\webapps\struts\WEB-INF\classes\first\

The struts-config.xml contains :
(C:\jakarta-tomcat-4.1.30\webapps\struts\WEB-INF\struts-config.xml)

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

</form-beans>

<action-mappings>

type="first.LookupAction"
name="lookupForm" >
<forward name="success" path="/quote.jsp"/>
<forward name="failure" path="/index.jsp"/>
</action>

</action-mappings>

</struts-config>
______________________________________________________________________

The second view is quote.jsp

___________________________________________________________
<html>

Can you see type and name attributes in tld (struts 1.2.4) below?
No you can not.
That is the problem.

I do not know why you missed package declaration and imports. I can not read this whole page again now (i am in mess now). If this is not the problem go to http://www.reumann.net/struts/lesson1.do and see how to make your struts app.

<IMPORTANT>package first;
import javax.servlet.http.HttpServletRequest;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;</IMPORTANT>

class LookupForm extends ActionForm
{

private String symbol = null;

public String getSymbol()
{
return (symbol);
}

public void setSymbol(String symbol)
{
this.symbol = symbol;
}

public void reset(ActionMapping mapping, HttpServletRequest request)
{
this.symbol = null;
}

}

Problem is with struts version[ Go to top ]
- Posted by: Saikat Mukherjee

There is a problem with the version of struts here. The book you are using is talking about struts 1.1 while the version you probably have installed is struts 1.2.4 (which is the latest stable version available at the moment). the <html:form > tag in the newer version does not require the explicit maping to the class definition. It uses the struts-config.xml for mapping purposes.

Removing the name and type attributes from the form tag solves the problem.
I am using j2sdk version:1.4.1_05, struts version:1.2.4 and tomcat version:5.0.12.

I am also having similar troubles with deploying struts. I am playing around with James Goodwill/R. Hightower book on Jakarta Struts and got stuck. After I have done everything according to the book I get the following error when I try to deploy:

I hope someone out there could help me. I have checked the codes, there has been no reference to ActionMappings (emphasise the "s"), only ActionMapping in the java codes and <action-mappings> in the config code.

Hi rajani,

When building your struts application try to use IDE envirionment like JBuilder,WebSphere etc. Thereby you can rectify the errors soon.

In this problem domain,the problem seems to be in TLD file.
In jakarta-struts directory you might have some ".war" files.Extract the file and copy the tld files alone and place it in your dir.stp the webservice and start it again.

The Attribute name you mention should match exactly in the config files.Check for the names.

It is better to follow a sample application development from web.

I followed the same application in IDE and i got correct.

Thanks,
Shivanandham.K

Exception creating bean of class first.LookupForm[ Go to top ]

Hi,

You did a small mistake.Dont remove the type and name attributes from <html:form> in index.jsp

They denote the action form and what action should take for the particular actionform bean.

DO:

1. Copy the struts-html.tld file from webapps/struts-blank.war file.

2.Replace the change that you made in index.jsp.Place the type and name attribute as it is in example.

check for the XXXForm.java and XXXXAction.java program that whatever method you invoke should match the keyword.

Ex. SetUsername,GetUsername.
I hope so now you will overcome the problem.

Thanks,
Shivanandham.K

Struts versioning issue[ Go to top ]

the problem is with the version incompatibility with Tomcat.

removing the "name" and "type" tag will solve the issue as pointed out.

Hi Man,
I think the solution given by previous person was 100% correct. I did the same thing i.e. deleting the name & type attributes from the <action> tag. Just verify your struts-config. Try to check the spelling mistake if u did...

my struts-config.xml looks like this :
<?xml version="1.0" encoding="ISO-8859-1" ?>
<struts-config>
<form-beans>
<form-bean name="lookupForm" type="ch03.LookupForm" />
</form-beans>

<action-mappings>
<action path="/Lookup" type="ch03.LookupAction" name="lookupForm">
<forward name="success" path="/quote.jsp" />
<forward name="failure" path="/index.jsp" />
</action>
</action-mappings>
</struts-config>

Your problem of not "Cannot retrieve mapping for /Lookup action" is only the configuration type mistake that u might have done in your struts-config.xml..

Let me know in case your stil your problem persist.

Important :
The declaration of <html:form> in index.jsp <html:form action="Lookup"> must match with

<action path="/Lookup" type="ch03.LookupAction" name="lookupForm"> coding of struts-config.xml.

Try to check action="Lookup" must be same with <action path="/Lookup">.
