Re: Installation - ant throws an exception
Hi,
I just started with ozone, and I had a similar problem as Raul Fiedler
described on Mon 7 Aug 2000. Lars Martin's reply to his message helped me to
fix the problem (Thank you).
I simply had to set a variable JAVA_HOME so that ant.bat sets the CLASSPATH
differently before running "java org.apache.tools.ant.Main".
My question is: where does this variable JAVA_HOME comes from? Until now I
did never need it, and I cannot find any documentation about it. Perhaps
somebody who knows more about it should explain the following lines in
ant.bat :
:checkJavaHome
if "%JAVA_HOME%" == "" goto runAnt
set CLASSPATH=%JAVA_HOME%\lib\tools.jar;%CLASSPATH%
:runAnt
set CLASSPATH=%ANT_HOME%\bin\ant.jar;%ANT_HOME%\bin\xerces.jar;%CLASSPATH%
java -Dant.home="%ANT_HOME%" org.apache.tools.ant.Main %1 %2 %3 %4 %5 %6 %7
%8 %9

You can find this class in the tools.jar file of your Java installation,
this
should be something like $JAVA_HOME/lib/tools.jar. It seems that you
didn't install your Java package properly. Did you set the environment
variable JAVA_HOME?
If so, which JDK do you use?
Which ant do you use, the one that comes woth the ozone distribution?
