#2 Linux 2.4 Java 1.3 & 1.4 run time error

[Gene Schiavone]

The following error was experienced when running
butterflyXMLEditor1.0.Beta with Java 1.3 or Java 1.4:

[root@BH6 Butterfly]# ./run.sh
Exception in thread "main" java.lang.NoSuchFieldError: java.awt.
Color: field BLACK not found
at butterfly.xmlview.test.Main.main(Main.java:125)

I'm on a Windows2K box and had the same error. I removed
Java 1.3 and installed Java 1.4 and the error was resolved.

I think this is probably that Butterfly looks for resources relative to the CWD, not to its own home directory. Suppose Butterfly is installed in

/home/simon/tmp/butterfly1.1

(which it currently is on my machine)

and the CWD is

/home/simon/workspace/mapping-generator

and you run

$BUTTERFLY_HOME/run.sh dbdef2hibernate-mapping.xsl

(which is what I just did) butterfly fails with

simon@apu:~/workspace/mapping-generator$ java.io.FileNotFoundException: /home/simon/workspace/mapping-generator/butterfly.conf (No such file or directory)

Having suggested this is the problem, I don't have a quick cure. I've personally altered run.sh on my machine to

/----
#!/bin/sh

if [ "$BUTTERFLY_HOME" = "" ]
then
BUTTERFLY_HOME=/home/simon/tmp/butterfly1.1
fi

for lib in butterfly.jar lib/jlz.jar lib/xml-apis.jar lib/avalon-excalibur.jar \
lib/avalon-framework.jar lib/commons-collections-1.0.jar lib/commons-JXPath.jar \
lib/commons-logging-1.0.jar lib/log4j.jar lib/logkit.jar lib/xep.jar lib/xerces.jar \
lib/fop.jar lib/batik.jar lib/xalan.jar
do
CLASSPATH=$CLASSPATH:$BUTTERFLY_HOME/$lib
done

java -Djava.endorsed.dirs="$BUTTERFLY_HOME/lib/endorsed" -classpath $CLASSPATH \
butterfly.xmlview.test.Main go
\----

This doesn't solve the problem, because Butterfly continues to look for its own resources relative to the CWD. What's needed (may actually be there, I haven't investigated in enough depth) is a command line arg to specify to Butterfly where it should look for resources e.g.

java -Djava.endorsed.dirs="lib/endorsed" -classpath $CLASSPATH butterfly.xmlview
.test.Main -butterfly-home $BUTTERFLY_HOME go

Like the artwork, BTW. Definitely adds personality - a sense that this is a real person's product and not some anonymous corporate production.

If you'd like to assign this bug (and any other Linux specific bugs) to me, I'll produce a patch.
