Q: I'm running VIVO in Tomcat on a MacIntosh. When I upload an image file, a
strange icon appears in the dock. What's up with that?
A: The image processing code in VIVO uses javax.imageio.ImageIO, which in turn
uses code in the java.awt package. By default, this package will open a work
area on your screen, producing this icon even though no visible window is
created.
You can prevent this by editing {tomcat}/conf/setenv.sh, and adding the
"java.awt.headless" option. For example,
export CATALINA_OPTS="-Xms1024m -Xmx1024m -XX:MaxPermSize=64m -Djava.awt.headless=true"
