ClassNotFoundException and System.setProperty

2003-01-24 07:54

Hi!

 

I have a chart with a scriptlet.

I have a web application.

 

Like in the exemple I set my jasper.reports.compile.class.path

 

System.setProperty( "jasper.reports.compile.class.path",

context.getRealPath("/WEB-INF/lib/jasperreports.jar") +

System.getProperty("path.separator") + context.getRealPath("/WEB-INF/classes/")

);

 

I would like to have a directory report with my chart.xml and my chartScriptlet.class.

 

Is it possible to change "/WEB-INF/classes/" for "/WEB-INF/report" ?

 

I tried this, but when my .class is'nt in "/WEB-INF/classes/", I have java.lang.ClassNotFoundException.

 

Thank!

Hi,

 

The /WEB-INF/classes directory is a very special

one because the Web server will automatically

load the classes placed there when running

your Web application.

If you place the scriptlet class in other directory,

the Web server would not be able to load the class

and therefore you get the error.

 

It is like placing one of your servlet classes into

some other location.

 

The same thing for the /WEB-INF/lib directory

in which you normally place your Web application

jar files.

 

I hope this helps.

Teodor
