Here is what I just did. Note I am actually inside a Win VM, at a cygwin
prompt.

Any ideas?

Re: Need help: Steps in your INSTALL doc failing
Hey - thanks for the quick reply! Ya know, I read that bit
but the jar file I have is named log4j-1.2-17.jar, and I thought
it comprised everything. When I downloaded the code, that's
the only jar file there was. Clearly, I was delusional! I'll go
look for the corresponding API and core jar files...
Thanks again!

Need help: Steps in your INSTALL doc failing
Hello -
I can write, compile, and successfully run a Java program
to look at a .jar file and list the classes defined therein, but
I can't for the life of me get your "Using log4j" java code shown
in 1-2.17's INSTALL doc to work.
Perhaps there's some other magic that needs to happen to get
this code snippet you wrote to yield output?
You can now test your installation by first compiling the following
simple program.
import org.apache.log4j.Logger;
import org.apache.log4j.BasicConfigurator;
public class Hello {
private static final Logger logger = Logger.getLogger(Hello.class);
public
static
void main(String argv[]) {
BasicConfigurator.configure();
logger.debug("Hello world.");
logger.info("What a beatiful day.");
}
}
-
I understand how CLASSPATH works, etc. I can get it to compile but
even if I again (with option -cp) specify exactly where the .class file is
that it just created from the compile, it still can't find what it needs.
Depending on where I've put things and what I tell it, I get one of these
failing results when I try to run the executable:
(1)
java.lang.NoClassDefFoundError: org/apache/log4j/Logger
at Hello.(Hello.java:6)
Caused by: java.lang.ClassNotFoundException: org.apache.log4j.Logger
at java.net.URLClassLoader$1.run(URLClassLoader.java:366)
at java.net.URLClassLoader$1.run(URLClassLoader.java:355)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(URLClassLoader.java:354)
at java.lang.ClassLoader.loadClass(ClassLoader.java:423)
at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308)
at java.lang.ClassLoader.loadClass(ClassLoader.java:356)
... 1 more
Exception in thread "main"
or (2)
Error: Could not find or load main class Hello
Please, I am an old UNIX geek but this is really really frustrating me.
I have looked literally EVERYWHERE to find out what the problem is
but of course I am apparently the first and only person to ever have this
problem. Ha!

Please test what you build.
