Using ANT to create .ear and .war files...

Hi all, quick question.

Trying to use Ant to create .war and .ear files to deploy to the latest release of oc4j

I am using the sample addressbook example that can be found on 
, however upon running the Ant tool, the response is nothing more than -
E:\addressbook>"c:\jdk1.2.2\\bin\java" -classpath "c:\jdk1.2.2\\lib\tools.jar;c:\jakarta-ant-1.4.1\\lib\jaxp.jar;c:\jakarta-a
\ora81\Apache\Perl\5.00503\bin\mswin32-x86;C:\Program Files\Oracle\jre\1.1.7\bin;C:\WINNT\system32;C:\WINNT;c:\jakarta-ant-1.4
.1\\bin;c:\jakarta-ant-1.4.1\lib" -D ant.home="c:\jakarta-ant-1.4.1\"
Exception in thread "main" java.lang.NoClassDefFoundError: ant/home=c:\jakarta-ant-1/4/1"

- it seems that, although the tool has 'kicked in' it has not been able to either 1) find the build.xml file 2) for some reason ant.home has been transposed to ant/home...

Anybody feeling brave...??!!

Thanks in adavance

Well, here are some points that *may* help, but don't quite seem to fit in this case.

- change ant.home to ANT_HOME
- for convenience, have ANT_HOME/bin added to your system path
- ant looks, by default,  for build.xml in the current directory
- try running ant with the -verbose flag to see if it provides any output more helpful.

Thanks for the reply coreyit,

Do you mean change the build.xml content from ant.home to ANT_HOME ? I have ANT_HOME as an environment variable as well as my path including the bin dir of Ant.

The trouble is that when I type ant I get:

Exception in thread "main" java.lang.NoClassDefFoundError: ant/home=c:\jakarta-ant-1/4/1" ...OR... just the outcome of running ant -?... very odd.

I've tried to run using all of the options but the outcome is always the the ant.home setup for UNIX? in which case need I change the whole shebang to ""-""

Cheers all the same...

No, I meant to be sure your system variable was ANT_HOME, which it is, so...?

I downloaded the orion and was mildly successful running ant with no changes to my system or additional downloads. It got as far as the compilation phase (ant target "ejb-classes") before failing because I don't have the javax.ejb package (which is probably included with the Orion download).

Here is a list of some of my system info that may be useful:
- using cygwin and dos command prompt
- using jdk 1.4
- ANT_HOME is set (with and without "." in the path)
- JAVA_HOME is set
- PATH has ANT_HOME/bin and JAVA_HOME/bin included
- steps:
  1) downloaded and unpacked (say, to TESTDIR)
  2) > cd $TESTDIR (contains build.xml and src directory)
  3) > ant

The two things puzzling me are
  1) if there is really also an "ant.home" variable set, where is that?
  2) why do your "." characters seem to be converted to"/" characters in both the var name and the value?

I suppose I may be able to track something more down if you replied with some system settings and steps your following as well. Not sure though. Sorry that this hasn't helped much.


one more idea. Try removing the following line from the build.xml:

<property name="build.compiler" value="classic" />

Thanks for the help,

I'll give that a go.  I've no idea why the system seems to have transposed the . for a /
Got a feeling that having JNDI / LDAP may be causing some unforseen probs.

Anyway thanks coreyit
good luck. :)
