Subject: RE: Problems with graphics on Tomcat 5.5.9


Trying again to make the graphics appear in my web app, I did a test web =
app
and I had been trying to start the Tomcat with =
-Djava.awt.headless=3Dtrue
option as I read in some forums

#export CATALINA_OPTS=3D"-Djava.awt.headless=3Dtrue"
#/usr/java/jakarta-tomcat/bin/startup.sh

But they do not appear either

The web test app can be found here =
http://www.actesoft.com:8080/Prueba/jsp/
and the wanted result after click on "Graficar" is something like this
http://www.actesoft.com/ejGrafico/ (static page)

Also I have try to insert in the Graficador.class constructor the next
System.set/getProperties lines


public Graficador(String Path){
super();
this.contexto =3D Path;
this.background =3D null;

//System.setProperty returns the current value before assignment
String vrPropiedad =3D System.setProperty("java.awt.headless", "true");

// Log the before assignment value to a log file to debug
logger.debug("BEFORE =3D java.awt.headless =3D " + vrPropiedad);

//and log the after assignmet value to a log file too
vrPropiedad =3D System.getProperty("java.awt.headless");
logger.debug("NOW =3D java.awt.headless =3D " + vrPropiedad);
}


And these are the log file lines the app write

2005-10-10 11:18:15,996 [-t] INFO [index.jsp] - Loading form
2005-10-10 11:18:15,999 [-t] INFO [index.jsp] - Form OK !

2005-10-10 11:18:25,549 [-t] DEBUG [Graficador] - Making a PNG image =

And here the app trhows an exception

Any idea is always welcome, thanks.
