Re: [Php-java-bridge-users] JasperReports problem

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

Thanks for the tip : I did not know that javac (i.e the one in=20
tools.jar) did not inherit the runtime classpath (but it seems logical=20
because, for example, I do not want my compilation be influenced by my=20
eclipse classpath).

I used the solution previously provided (i.e set java.classpath in the=20
php.ini) which seems to do the same thing (put the jars in the system=20
class loader).
I prefer to stay with this solution because it is clearly more simple=20
than to hook the JasperReports sources or than to set a system property=20
in an obscure part of the code (what I mean is that if other=20
applications use PHP-Java-bridge, it is simpler for them to know that=20
there already are some classes in the system classpath via php.ini).

Anyway, I will fill a bug on JasperReports to say that it will be good=20
to provide the necessarly used runtime jars to the javac compiler.

Thanks to take time to think on my problem.

Regards,
chris
