ant can't find javac compiler
Dear dev@ant.apache.org, I am using ant to compile my struts webapp. I am using Linux 2.4.27 and running ant (1.5.2-26) from my shell which is bash. My environment variables which I set in my .bash_profile are: $JAVA_HOME=/usr/java/jdk1.5.0_02 $CLASSPATH=/usr/java/jdk1.5.0_02/lib:/usr/java/jdk1.5.0_02/jre/lib Here is my problem. When I compile my classes using the default compiler for my system (kjc) I get this error: error: Can't find default package `java.lang'. Check the CLASSPATH environment variable and the access to the archives Which I can live with (even though my CLASSPATH variable is probably correct) since I really ought to be using the jdk1.5.0_02 compiler. If I set the compiler attribute of javac task in my build.xml to modern, it should use the javac compiler that comes with my JDK. When I do I get this error: Unable to find a javac compiler; com.sun.tools.javac.Main is not on the classpath. Perhaps JAVA_HOME does not point to the JDK If I run the javac command manually from the command prompt, something like this: javac -cp MY/VERY/LONG/CLASSPATH/ src/uk/co/webotech/myproject/MyClass.java It compiles fine... By the way, typing which javac in my shell returns /usr/java/jdk1.5.0_02/bin/javac. How can I get ant to find javac? Any help with this would be greatly appreciated!

Re: ant can't find javac compiler
Martin, I tried changing my $PATH as you suggested but that didn't help. Also, java and javac are both the same version (1.5.0_02). I wonder if ant runs it's processes in another shell - one perhaps that doesn't pick up my personal env variables? Maybe it doesn't even run them in bash? Could it be that ant tasks are run by a different Linux user which needs to be set up? I'm thinking out loud... if that is possible by email!

Good Afternoon Paul The documentation for the ant javac task is available at http://ant.apache.org/manual/CoreTasks/javac.html 2 things.. set fork = yes take a look at the parameter called executable Complete path to the javac executable to use in case of fork=yes HTH, Martin- - Original Message - From: [EMAIL PROTECTED] To: Ant Developers List dev@ant.apache.org Sent: Thursday, September 22, 2005 10:27 AM Subject: Re: ant can't find javac compiler Martin, I tried changing my $PATH as you suggested but that didn't help.
