Would like to use a script to input Math functions...

Right! I just had it in the wrong folder!

I did it, and got this:

Code:

org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: 5 in the jsp file: /Hello.jsp
Generated servlet error:

line 5:

Code:

<%// ability_calculator.jsp
   double CalculateAbility( double effortValue, double baseValue,
        double individualValue, double level, double personality );
   {
        double quarterEffort = Math.Floor( effortValue / 4 );
        double doubleBase = baseValue * 2;
        double levelValue = 
                ( doubleBase + individualValue + quarterEffort ) * level;
        double levelPercentage = levelValue / 100;
        double personalityValue = 
                Math.Floor( ( levelPercentage + 5 ) * personality );

        return personalityValue;
   }
%>

Ideas?

(p.s. Thanks a ton for your time on this Twey!)

Extraneous semicolon after the function declaration.

took it out, and got:

**sigh** I am screwing up somewhere.... it all started when I woke up one day....

The following compiled here (although I didn't execute it) {

Code:

   double CalculateAbility( double effortValue, double baseValue,
        double individualValue, double level, double personality )
   {
        double quarterEffort = Math.floor( effortValue / 4 );
        double doubleBase = baseValue * 2;
        double levelValue =
                ( doubleBase + individualValue + quarterEffort ) * level;
        double levelPercentage = levelValue / 100;
        double personalityValue =
                Math.floor( ( levelPercentage + 5 ) * personality );

        return personalityValue;
   }

Is it just me?

I mean, sure I know how to read, and I followed the tut, got it running, tested with 4 different test scripts, all worked.

I put this one in, and get these error codes.

Just to be sure here is the full jsp page:

ability_calculator.jsp:

Code:

<HTML>
<HEAD>
<TITLE>Ability Calculator</TITLE></HEAD>
<BODY BGCOLOR="#FDF5E6">
 <%
 double CalculateAbility( double effortValue, double baseValue,
        double individualValue, double level, double personality )
   {
        double quarterEffort = Math.floor( effortValue / 4 );
        double doubleBase = baseValue * 2;
        double levelValue =
                ( doubleBase + individualValue + quarterEffort ) * level;
        double levelPercentage = levelValue / 100;
        double personalityValue =
                Math.floor( ( levelPercentage + 5 ) * personality );

        return personalityValue;
   }
   %>
Personality value for values given:  <%= CalculateAbility(
  Double.parseDouble(request.getParameter("eff")),
  Double.parseDouble(request.getParameter("bas")),
  Double.parseDouble(request.getParameter("ind")),
  Double.parseDouble(request.getParameter("lev")),
  Double.parseDouble(request.getParameter("per"))
) %>
</BODY>
</HTML>

as well as the FULL error output from the local server:

It's something simple isn't it? It always is... some stupid little space or carriage return or some thing...

BTW, just so I understand.. the error lines, say this one:

An error occurred at line: 5 in the jsp file: /ability_calculator.jsp
Generated servlet error:
Syntax error on token "(", ; expected

This is saying there is a syntax error in line 5 of the jsp page, and that it detects the ( symbol, and is expecting a ;

right?

**Twey** · 05-17-2006, 08:15 PM

Hahahahaha.
Oh dear, I made a really stupid mistake.

Functions can't be defined within scriptlets; you need to use a declaration. Add ! to the end of the opening tag for the scriptlet in which the function is defined.

**BLiZZaRD** · 05-17-2006, 08:28 PM

okay if I understood correctly, I did this:

Code:

 <%!
 double CalculateAbility( double effortValue, double baseValue,
        double individualValue, double level, double personality )
   {
        double quarterEffort = Math.floor( effortValue / 4 );
        double doubleBase = baseValue * 2;
        double levelValue =
                ( doubleBase + individualValue + quarterEffort ) * level;
        double levelPercentage = levelValue / 100;
        double personalityValue =
                Math.floor( ( levelPercentage + 5 ) * personality );

        return personalityValue;
   }%>

Adding the ! after the first %

Now, the errors are gone, but I get this:

Code:

org.apache.jasper.JasperException: Exception in JSP: /ability_calculator.jsp:21

18:    }%>
19: Personality value for values given:
20: <%=CalculateAbility(
21:   Double.parseDouble(request.getParameter("eff")),
22:   Double.parseDouble(request.getParameter("bas")),
23:   Double.parseDouble(request.getParameter("ind")),
24:   Double.parseDouble(request.getParameter("lev")),


Stacktrace:
	org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:504)
	org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:393)
	org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314)
	org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:802)

So I am guessing that brings me back to your comment about passing the "eff" "per" etc using POST or GET... but where?

Do I do it like in php and at the top say eff=30 or something?

**Twey** · 05-17-2006, 08:31 PM

Yep, you can do that, or you can write a form.

**BLiZZaRD** · 05-17-2006, 08:37 PM

A form is what I want though right? So I can enter the different variable each time, without having to change the jsp page??

So would I make an html page with text boxes for the variables and then a submit button that will call the jsp page?

**Runs to look at the tut link from before**

**Twey** · 05-17-2006, 08:43 PM

Ayup. You could just change the GET variables in the address bar, though, like you suggested before.
