noxmldesign - error with n characters in str

2003-05-14 05:15

Hi,

I'm generating a JasperDesign at runtime (no XML).

I'm getting the following error when I pass a String into the textField element that contains (n) characters.

/home/enrico/SubReportDesign1.java:116: unclosed string literal

value = (java.lang.String)("Ferrari

^

/home/enrico/SubReportDesign1.java:118: unclosed string literal

");

^

/home/enrico/SubReportDesign1.java:119: ')' expected

break;

^

/home/enrico/SubReportDesign1.java:181: unclosed string literal

value = (java.lang.String)("Ferrari

^

/home/enrico/SubReportDesign1.java:183: unclosed string literal

");

^

/home/enrico/SubReportDesign1.java:184: ')' expected

break;

^

/home/enrico/SubReportDesign1.java:246: unclosed string literal

value = (java.lang.String)("Ferrari

^

/home/enrico/SubReportDesign1.java:248: unclosed string literal

");

^

/home/enrico/SubReportDesign1.java:249: ')' expected

break;

See error messages above.

 

Any ideas how I can fix this?

Hi,

 

You have to replace 'n' character with the "n" sequence in the String values you put inside

the text field expressions.

Because the expressions are used to create

a Java source file at report compile time.

 

I hope this helps.

Hi Teodor,

 

I'm sorry, I don't understand. Can you be more specific?

Here's my code:

JRDesignTextField tf = new JRDesignTextField();

tf.setX(x);

tf.setY(y+20);

tf.setWidth(columnSize);

tf.setHeight(columnHeight);

tf.setTextAlignment(JRTextElement.TEXT_ALIGN_LEFT);

tf.setFont(normalFont);

tf.setStretchWithOverflow(true);

JRDesignExpression expression = new JRDesignExpression();

expression.setValueClass(java.lang.String.class);

//eg. String val = "Blah blah blah.nBlah blah blah.n";

expression.setText("""+val+""");

tf.setExpression(expression);

band.addElement(tf);

Hi,

 

Well, you see? You have already introduced escape

character to make it for the quotes arround the text,

in the text field expression.

But what about the quotes inside the text? And what

about the newline characters there?

We have to escap them in the same manner.

Because the text you supply there will be used in the

source code of a real java class. And this class file

will not compile otherwise.

 

I still don't see why you cannot pass the text field

content at runtime using parameters and you put

it in the text fields at design time.

 

I hope this helps.

Teodor
