textField_3 help please!

2003-12-11 08:42

Hello i'm trying to build my first report with jasper.

 

when i call JasperPrint jp = JasperManager.fillReport(isReport, null, flussiDS);

 

The manager firstly fills all the variables (i've debugged it).

 

then the method exits with:

HTTP ERROR: 500 Error evaluating expression value : textField_3

 

I really don't know A) what this message is B) how to solve the problem.

 

Please help me. bye.

looks like a textFieldExpression can't be evaluated.

you should post your xml report definition.

Hi,

 

This is only the exception message. The cause is

contained in the JRExpression that you catch.

Print the stack trace on the console to see what is

the cause.

Put the fillReport call inside a try/catch if you haven't

already don so.

 

If you get the CVS version, you'll also see the

text of the report expression that throws the exception.

 

I hope this helps.

yes it was a class cast exception between an integer and a string in an expression.

so my expression is :

 

"Tourists flows: " + $F{month}.toString() + $F{year}.toString()

 

what's wrong with that ?

Hi,

 

What is the type of the <textFieldExpression>?

Check the "class" attribute.

And what do you use as report compiler?

The BSH compiler?

 

I hope this helps.

Helpful Hint:

 

If you had included your report xml in your first message, likely we could have helped you long ago.
