BUILD FAILED: J2SE5 required

[parish]

I'm trying to build the code examples in "Thinking In Java" under FC11 and I keep throwing the error:

/java/TIJ4-code[191]% ant
Buildfile: build.xml
run:
build:

BUILD FAILED

/java/TIJ4-code/build.xml:51: The following error occurred while executing this line:
/java/TIJ4-code/object/build.xml:29: J2SE5 required

Total time: 0 seconds

I'm pretty sure this is a trivial problem to correct, but being new to java, I'm kind of lost. Googling led me to believe that jre-1_5_0_17-linux-i586.rpm was J2SE5 in Fedora speak, but installing it did not help. I do have java and jdk working along with the netbeans IDE, although I'm also experimenting with the commandline compilation, so I think my installation is relatively complete.

Any help would be greatly appreciated.

you probably want to make sure the correct java is being picked up in your PATH


do 'java -version' If it says something like 'IceTea' for that particular build file you may need to change your PATH so that when you do 'java -version' it says something more like.

java version "1.5.0_17"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_17-b04)

Thanks for the suggestion, but it turns out I was attempting to solve the wrong problem...

After a bit of learning about ant, java, xml files, etc., I figured out to edit the build.xml files so that ant was testing for my installed java version (1.6) instead of 1.5. Now it is compiling everything as it should.

Cheers,
