running a jar example file with hadoop

Please go easy on me. I just started linux and hadoop at the same time. I have almost zero experience with linux and a complete beginner with hadoop.

I downloaded the file hadoop-1.1.1-bin.tar.gz from here:

http://www.motorlogy.com/apache/hadoop/common/hadoop-1.1.1/

I was able to unpack it.

I am following a tutorial that tells me to run:

bin/hadoop jar hadoop-*-examples.jar

I am getting this error:

agordon@Ubuntu32:/hadoop/hadoop-1.1.1$ bin/hadoop jar hadoop-*-examples-1.0.3.jar
Exception in thread "main" java.io.IOException: Error opening job jar: hadoop-*-examples-1.0.3.jar
    at org.apache.hadoop.util.RunJar.main(RunJar.java:90)
Caused by: java.io.FileNotFoundException: hadoop-*-examples-1.0.3.jar (No such file or directory)
    at java.util.zip.ZipFile.open(Native Method)
    at java.util.zip.ZipFile.<init>(ZipFile.java:214)
    at java.util.zip.ZipFile.<init>(ZipFile.java:144)
    at java.util.jar.JarFile.<init>(JarFile.java:152)
    at java.util.jar.JarFile.<init>(JarFile.java:89)
    at org.apache.hadoop.util.RunJar.main(RunJar.java:88)

What am i doing wrong? thank you for your guidance.

Instead of hadoop-*-examples.jar use the full name of the jar file.
