I have uploaded the PJA jar files in a folder of
a web application in TOMCAT 4.0.6
on AIX 4.3.3 with Java 1.3.1

when I run the classic example below to display a jpeg
generated on the fly on a java server page, I am not
able to see the text "Hello" is not drawn.
Seems that g.drawString ("Hello", 30, 50); method is not working...
If I set java.awt.fonts=tomcat_home/webapps/pjaf
that is the folder where I have included some pjaf files generated
with PJAFontCapture.sh I get the error
no fonts found in tomcat_home/webapps/pjaf
and tomcat shutdown

What could it be?
What could I try to visualize the text with drawString method?
When I start tomcat I specify where my java libs fonts are like with the following:
CATALINA_OPTS="$CATALINA_OPTS -Xbootclasspath/a:$CATALINA_HOME/webapps/libadd/pja.jar -Dawt.toolkit=com.eteks.awt.PJAToolkit
-Djava.awt.graphicsenv=com.eteks.java2d.PJAGraphicsEnvironment -Djava.awt.fonts=$JAVA_HOME/jre/lib/fonts"

Please let me know.
Thanks.

You must put some True Type fonts in your the directory contained in java.awt.fonts property.
With Java 1.3.1, .pjaf font files are not used unless you set com.eteks.awt.nojava2d system property to true and in that case, you can't use any methods of Java2D including the java.awt.image.BufferedImage class (but you may create images with the createImage(int width, int height) method of java.awt.Frame).
