[Php-java-bridge-users] float type pb

[<php...@li...>]

Hi everyone,

I'd like to use com.lowagie.text.pdf.PdfContentByte setFontAndSize and
showTextAligned functions but I have a problem in passing them a float.
Here is my code:

...
$cb = $writer->getDirectContent();
$bf = new Java("com.lowagie.text.pdf.BaseFont");
$bf->createFont("Helvetica", "Cp1252", false);
$cb->setFontAndSize( $bf , 12);
...
I got this error:
Fatal error: Uncaught [o(Exception):"java.lang.Exception: Invoke failed:
[o(PdfContentByte)]->setFontAndSize((BaseFont)c(BaseFont), (float)o(Float)).
Cause: java.lang.IllegalArgumentException: argument type mismatch [...]

It seems '12' is considerated as an Object Float and not a primitive type
float.
I had try different things like making an instance of a Float and call the
floatValue() or parseFloat() functions in order to get the float type value
but can't make it works.
How could I get the real primitive float type value?

I use PHP 5.1.1, JRE 1.5.0 Update 11  and iText-1.3.1 jar on Windows XP.

Help would be greatly appreciated!

Shouldn't be BaseFont an instance?  My guess is that
$bf = $bf->createFont(...) should correct this
problem. 

BTW: For backward compatibility the bridge allows
sloppy coding:

 new Java("com.lowagie.text.pdf.BaseFont");

is valid even though the above code should immediately
throw an exception. If you set the log level to 3
(which is default), you should see a warning message
in the JavaBridge.log file.

It's more likely that the problem is the first
argument, not the second. float is autoconverted into
a Float, so this shouldn't be the problem.

But you're right, the "illegal argument exception"
should state which argument is illegal, and why! At
the moment we simply pass the exception we've obtained
from Java. In the next version, 4.0.2 we should change
this: wrap the obtained exception and pass more
information to the client.
