org.apache.jasper.JasperException: An exception occurred processing JSP page /jsps/ActionForms/Displ

[Kalith Aazad]

Hello everyone,
I am writing this simple struts application . I am getting errors and its hard to debug since I dont know what exactly is going wrong. Please help me out in this..Thank you very much in advance.

Here is the struts-config.xml for the same:

  <?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE struts-config PUBLIC
 "-//Apache Software Foundation//DTD Struts Configuration 1.0//EN"
 "http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd">

<struts-config>
	<form-beans>
		<form-bean name="ProductFormBean_XML"
			type="chapter2.multiPageForms.ProductForm.ProductFormBean" />
	</form-beans>

	<!-- ========== Action Mapping Definitions ============ -->
	<action-mappings>

		<action path="/displayProductForm" forward="/jsps/ActionForms/DisplayAddProductForm.jsp" />


		<action path="/saveProductForm"

		</action>

		<!--
			<action path="/addProduct"
			type="edu.productDemo1.addProductDemo.AddProduct" scope="request" >
			<forward name="success" path="/jsps/showProductInfo.jsp" /> <forward
			name="failure" path="/jsps/displayAddProductForm.jsp" /> </action>
		-->
	</action-mappings>

	<!--
		========== Controller Configuration ================================
	-->
	<controller>
		<!--
			The "input" parameter on "action" elements is the name of a local or
			global "forward" rather than a module-relative path
		-->
		<set-property property="inputForward" value="true" />
	</controller>

</struts-config>
  

This is the formBean--

 package chapter2.multiPageForms.ProductForm;

import javax.servlet.http.HttpServletRequest;

import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionMessage;

public class ProductFormBean extends ActionForm {
	private String productName;
	private String price;
	private String description;

	public ActionErrors validate(ActionMapping mapping,
			HttpServletRequest request) {

		ActionErrors actionErrors = new ActionErrors();
		if (this.getProductName() == null)
			actionErrors.add("ProductName Error", new ActionMessage(
					"ProductName is not filled"));
		if (this.getPrice() == null)
			actionErrors.add("Price Error", new ActionMessage(
					"Price is not filled"));
		if (this.getProductName() == null)
			actionErrors.add("Description Error", new ActionMessage(
					"Description is not filled"));
		return actionErrors;
	}

	public String getProductName() {
		return productName;
	}

	public void setProductName(String productName) {
		this.productName = productName;
	}

	public String getPrice() {
		return price;
	}

	public void setPrice(String price) {
		this.price = price;
	}

	public String getDescription() {
		return description;
	}

	public void setDescription(String description) {
		this.description = description;
	}

	@Override
	public void reset(ActionMapping mapping, HttpServletRequest request) {
		// TODO Auto-generated method stub
		super.reset(mapping, request);
		this.price = "";
		this.productName = "";
		this.productName = "";

	}

}
 

This is the actionClass--

   package chapter2.multiPageForms.ProductForm;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

public class SaveProductAction extends Action {

	private static PopulateData populate;
	@Override
	public ActionForward execute(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response)
			throws Exception {
		// TODO Auto-generated method stub
		//return super.execute(mapping, form, request, response);
		ProductTO product = new ProductTO();
		ProductForm productForm = (ProductForm) form;
		product.setProductName(productForm.getProductName());
		product.setPrice(productForm.getPrice());
		product.setDescription(productForm.getDescription());
		request.setAttribute("productBean", product);
		//populate = new PopulateData(form,request);
		if(product.equals(null))return mapping.findForward("errors");
		return mapping.findForward("success");
		
		
	
	
	}

	
}

 

This is the JSP for the same--

   <%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

</head>
<body>
<html:errors/>
<html:form action="/saveProductForm" method="GET">
<table>
<tr>
<td>Product Name:</td>
<td><html:text property="productName"/></td>
</tr>

<tr>
<td>Description:</td>
<td><html:text property="description"/></td>
</tr>


<tr>
<td>Price:</td>
<td><html:text property="price"/></td>
</tr>

<tr><td><html:submit>Submit</html:submit></td>
<td><html:reset/></td>
</tr>

</table>
</html:form>

</body>
</html>
 

The transfer object is as follow-

 
package chapter2.multiPageForms.ProductForm;

import java.io.Serializable;

public class ProductTO implements Serializable {
	
	private String productName;
	private String price;
	private String description;

	public String getProductName() {
		return productName;
	}

	public void setProductName(String productName) {
		this.productName = productName;
	}

	public String getPrice() {
		return price;
	}

	public void setPrice(String price) {
		this.price = price;
	}

	public String getDescription() {
		return description;
	}

	public void setDescription(String description) {
		this.description = description;
	}
	

}

   

This the output view--

   <%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

Please help ..I m trying to debug the app for 2 days now!

[David Newton]

Wow, that's an old version of Struts--any reason you're learning it?

In any case--the thing I'd try first would be to rename the form bean by removing the "_XML" part--I don't know if it'll fix the issue, but it's easy to try.

[Kalith Aazad]

The reason why I am learning Struts1 is that there are lot many applications in that. it adheres to basic rules like form-bean.
Its widely used .

[Kalith Aazad]

@David..removing of _XML doesnt work.

[David Newton]

Kalith Aazad wrote:The reason why I am learning Struts1 is that there are lot many applications in that. it adheres to basic rules like form-bean. Its widely used .

I was actually referring to the 1.0 part; that's like a decade old. If you're happy doing maintenance work, Struts 1 is fine--enjoy!

(Although I wouldn't call "form-bean" a "basic rule"--other frameworks behave quite differently.)

[David Newton]

Check out the Javadocs for ActionMessage--I don't recall for 1.0, but nothing 1.1+ takes an immediate string; they're expecting a resource/message key.

[Kalith Aazad]

I am confused...You want me to create a message resource file in the WEB-INF/classes directory for the error to be removed??

[David Newton]

Did you look at the Javadocs for the version of Struts you're using? I have no idea what version you're using-this makes it more difficult to help.

[Kalith Aazad]

How to check the version of Struts?
I have imported the following jar files and tld's in my eclipse folder
here is a snapshot of it.
Image of JAR and taglib files

[David Newton]

You don't even know what version of Struts you're using?!

[Kalith Aazad]

Here is the thing i found out of struts.jar from manifest file.


Manifest-Version: 1.0
Ant-Version: Apache Ant 1.6.1
Created-By: 1.3.1_04-b02 (Sun Microsystems Inc.)
Extension-Name: Struts Framework
Specification-Title: Struts Framework
Specification-Vendor: The Apache Software Foundation
Specification-Version: 1.2.9
Implementation-Title: Struts Framework
Implementation-Vendor: The Apache Software Foundation
Implementation-Vendor-Id: org.apache
Implementation-Version: 1.2.9
Class-Path: commons-beanutils.jar commons-digester.jar commons-fileup
load.jar commons-logging.jar commons-validator.jar jakarta-oro.jar

[David Newton]

My statement about reading the Javadocs for ActionMessage still apply: it expects a key, not a string literal.

[David Newton]

(Note I'm giving you a hint about how to solve the problem: if you do not read the Javadocs, you may not discover how to do what it is you wish to do.)

[Kalith Aazad]

Thank you. I am creating a applicationResource.properties file in the src/resources directory and mapping it onto struts-config.xml and will then create entities in the applicationResource.properties file to check if the appropriate keys are being called. Will keep you posted on this. I appreciate the help,.

[David Newton]

That is one solution; there is another.

[Kalith Aazad]

Here is the thing i did,
I created the entity:
<message-resources parameter="resources.MessageResources" />

in the resources folder.

After that i added:
error.productName = Product name not found
error.price = price not entered
error.description = description not entered

to the MessageResources.properties
After that I modified the validate method in the ActionForm

public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {

ActionErrors actionErrors = new ActionErrors();
if (this.getProductName() == null)
actionErrors.add("ProductName", new ActionMessage(
"error.productName"));
if (this.getPrice() == null)
actionErrors.add("ProductPrice", new ActionMessage(
"error.price"));
if (this.getDescription() == null)
actionErrors.add("ProductDescription", new ActionMessage(
"error.description"));
return actionErrors;
}

Now I still get the same error

note The full stack trace of the root cause is available in the Apache Tomcat/6.0.20 logs.

[David Newton]

At what point does the error occur? Are you trying to access the JSP page directly? Did you understand when I told you that reading the documentation would show you how to avoid creating a resource file (although this does not appear to be the immediate problem)?

Side notes: why do you configure your taglibs in the web.xml? That hasn't been necessary for years. How do you expect this code to work (besides that it appears to be completely unnecessary)--if it's null, what do you think this code would do?

product.equals(null);

[Kalith Aazad]

This seems crazy, but I guess I used netbeans, as i used to use earlier, just tweaked the web.xml ...and cleaned and built the project.
Added the standard.jar and jstl.jar files
And the small app worked.

Thank you so very much for helping me out in this situation.I really appreciate it.

[Kalith Aazad]

Here is the final working Code for the entire app.
