Some question about installation...

[Tsai Fu-Ming <sa...@pchome.com.tw>]

Hello:
I have some problem when I installed ANT.
The version of ANT that I installed is 1.6.0, The version of JAVA is
1.4.2_03, and I use redhat 9.0.
After I installed the binary edition of ANT, I tried to type "ANT -version".
The system has following message:

[root@localhost script]# ant -version
java.lang.IllegalArgumentException
at sun.net.www.ParseUtil.decode(ParseUtil.java:155)
at sun.misc.FileURLMapper.getPath(FileURLMapper.java:47)

at org.apache.tools.ant.launch.Launcher.main(Launcher.java:90)

Obviously, the ANT can not run............

I tried to find a solution about this case.However, when I use the ant
file of the version 1.5.4 of ANT,
the system has the following message:

[root@localhost script]# ant -version
Apache Ant version 1.6.0 compiled on December 18 2003

My problem is why the ANT can not run when I use the ant file of the
version 1.6.0, but the ANT can run
when I use the ant file of the version 1.5.4. Please reply me if anyone
knows. Thanks.
