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

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:

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

**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:

Code:

Apache Tomcat/5.5.17

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?

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.

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?

Yep, you can do that, or you can write a form.
05-17-2006, 08:37 PM
BLiZZaRD

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**

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