Hi,

While converting a struts 2 application to struts 1.x, I encountered the following questions on my mind. Any one know the answer?

1. In struts 2, the label can automatically have '*' for 'required' fields. Is there such in struts 1.x?

2. My validation, in struts 1.x, using 'double' and 'doubleRange' doesnt work. Any reason it wouldnt work? I have given the correct attributes. The jsp also has the javascript struts tag, and attributes on the 'form' tag for the validation.

3. My login page struts 1.x password field ideally is masked, i.e. an asterisk is shown while typing the password. Is it possible in struts 1?

4. is jstl/el useable in struts 2, just like it is in struts 1.x?

5. is there any issues in jstl tags inside struts tags, and struts tags inside jstl tags, for both struts 1.x and 2?

Hoping for your ideas.

No, Struts 1 will not do this.

I don't know what the problem is here. If you need help debuggin it, post your code.

Just use the html:password tag.

Yes, it is. Remember that Since Struts 2 must run in a Servlet 2.4 container, EL expressions can be placed anywhere in the JSP without a c:out tag.

None that I'm aware of as long as you're using Struts 1.3. One issue with earlier versions is that you couldn't use indexed="true" inside a JSTL c:forEach loop. That's fixed in 1.3, though.

Hi,

Below are my codes.

The validation for the double and doubleRange is not working.

What version of Struts are you using? Does the validation work for other fields on the same page? Does the "required" validation on this field work? When you say it doesn't work, what do you mean? That it just accepts invalid values without complaining?

With that code above, the 'required' is working. A pop up appears when the 'price' is empty.

If I put a valid value like '5', it is processed correctly.

However, if I put an invalid value like 'xx', it doesnt complain. Zero is saved in to mysql (via ejb entity bean persistence).

You didn't answer my question about which version of Struts you're using. The reason I asked it is that your validation code looks like it should work for Struts 1.3 but may not for previous versions. If you're using a previous version, consult the documentation for the version you're using.
