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.

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.)

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.

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

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.

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

(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.)

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,.

That is one solution; there is another.

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

type Exception report

message

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

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?

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.

Here is the final working Code for the entire app.

Web.xml--



struts-config.xml-->



ProductFormBean.java -->

ProductTO.java -->

SaveProductAction.java -->

DisplayAddProductForm.jsp -->

ShowProductForm.jsp -->



But thank you so much for guiding me.

Please UseCodeTags when posting code or configuration. Unformatted code and configuration is unnecessarily difficult to read. You can edit your post by using the button.
