saving svg as jpeg on tomcat server
whoops i might have sent this email be4 prematurely.... rewriting just
to make sure.....
Hello all,
I have a function to save my svg document as a jpeg. i fixed my code
from be4 so unix or windows filepaths shouldnt make a difference. it
works fine in windows. but on unix, it saves a 0 kb jpg and throws an
exception somewhere as my code does not go completely through and get
the standard 'The page cannot be displayed' page.
I was wondering am i doing something screwy here?
public static void saveJPEG(Document svgDoc, String fullPath,
PrintWriter out) {
//printwriter used for debugging in servlet
JPEGTranscoder t = new JPEGTranscoder();
FileInputStream blah = null;
TranscoderInput input = null;
FileOutputStream ostream = null;
TranscoderOutput output = null;
File f = null;
input = new TranscoderInput( svgDoc );
f = new File(fullPath+ "yyyy.jpg");
try {
ostream = new FileOutputStream(f);
} catch(FileNotFoundException e) {
e.getMessage();
}
output = new TranscoderOutput(ostream);
try {
>stack trace says there is a problem here....
t.transcode(input, output);
} catch( TranscoderException e) {
e.getMessage();
}
try{
ostream.flush();
ostream.close();
} catch(IOException e) {
e.getMessage();
}
}
here is a stack trace on tomcat if anyone wants a look:

Yes, normally when the AWT toolkit is booted it contacts the
X Server so it can provide info about the 'graphics environment'
(color depth, fonts etc). Headless means that there isn't a
display attached.

I took off early from work to come back to college n try it out. i
cannot express the joy and satisfaction of finally getting some Batik
to work with Tomcat! hah.
I am gonna break out some inspirational 70's rock music: "Dont Stop
Beleivin' " heh.
I guess some imaging/gui type code needs X support off? This is what
headless means? This seems to be what i found out from googling.

hey thanx for the tip guys. I'll try it tonight... Also I am curious
what exactly does this headless option for awt have to do with batik?
Does everyone who uses tomcat and batik do this the 1st time or
special cases (i just installed the server last month so it hasn't
seen much action other than batik)?
thanks,
Arian

I always get that exact error with fresh installs of Sun JDK and
Tomcat if -Djava.awt.headless=true is missing. It took me a few
moments to figure it out the first time.

I don't think so, but it looks like the tomcat
JVM might be a little confused/corrupt. What version
of java is it using?
Are you running tomcat with '-Djava.awt.headless=true'?
Normally you get a can't start AWT message but since
this is the first time AWT is accessed it might be
related. Or was someone using the headless AWT replacement
at one time? I think that set a property that was supposed
to replace the Sun Graphics engine. Perhaps those classes
weren't copied over?
