um, i have /usr/local/java/bin in my PATH but i followed your line of
thinking: if i do 'java -classpath ./hsql.jar org.hsql.Server' from one
terminal and the server comes up (i'm prompted with 'Server 1.4 is running').
i can then go away to another terminal and run the run.sh script for jBoss
and everything works wonderfully.
i've looked at org/jboss/main/jdbc/HypersonicDatabase.java and added some
extra processing (like a dump of the exception that's stopping this
starting - why isn't that in there!) and it IS because it cannot execute
java!
ok ... calming down a little ... you should never, that's NEVER, hard code
executable names or paths in your code. it is almost unbelievable that
the line:
proc = Runtime.getRuntime().exec("java -classpath ../lib/ext/hsql.jar
org.hsql.Server");
would appear in code. what happens if the java executable changes name?
what happens if the Hypersonic server class changes its name? i'd much
rather see this in a configuration file, so:
i have updated the version on my machine to read this command from the
conf/jboss.conf file by updating the HypersonicDatabase constructor to
take a String and store it in a final member variable. the conf/jboss.conf
file now reads (for the Hypersonic bit):
<MLET CODE = "org.jboss.jdbc.HypersonicDatabase" ARCHIVE="jboss.jar,hsql.jar"
CODEBASE="../lib/ext/">
<ARG TYPE="java.lang.String" VALUE="/usr/local/java/bin/java -classpath
../lib/ext/hsql.jar org.hsql.Server">
</MLET>
someone want to check what i've done and update the code in the CVS as
this will probably solve a lot of problems!
anyway, now that i have the system working i'm going to try it out.
Cheers,
Matt
