newbie problems initializing hbase from java

hi all -
I'm a new (would be) user ,yet I already have a question... it is probably
pretty silly, but I couldn't find anything in the FAQ. 

Wen trying to run the unit tests for 0.2.0 I get the following error
:java.io.FileNotFoundException:
file:/home/yoav/workspace/hbase-0.2.0/bin/webapps/dfs 
I have notices in the build.xml a comment saying it may have to do with jar
ordering. when I run my own tests, I get an 
java.lang.ExceptionInInitializerError after calling HBaseConfiguration(),
which I guess has something to do with available native libraries / jars too 

any suggestions ?

Jars compiled w/ 1.5 should run w/o issue on a 1.6 JVM.  Its if you try 
to go the other way round that you'll have issue.

Thinking more on this, are you doing this up in eclipse?  If so, order 
of items on the CLASSPATH is important (Will be less important after 
HBASE-785 goes in).  Here's my eclipse .classpath:

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
    <classpathentry kind="src" path="src/java"/>
    <classpathentry kind="src" path="src/test"/>
    <classpathentry kind="con" 
path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
    <classpathentry kind="lib" path="lib/commons-cli-2.0-SNAPSHOT.jar"/>
    <classpathentry kind="lib" path="lib/commons-collections-3.2.jar"/>
    <classpathentry kind="lib" path="lib/commons-httpclient-3.0.1.jar"/>
    <classpathentry kind="lib" path="lib/commons-logging-1.0.4.jar"/>
    <classpathentry kind="lib" path="lib/commons-logging-api-1.0.4.jar"/>
    <classpathentry kind="lib" path="lib/commons-math-1.1.jar"/>
    <classpathentry kind="lib" path="lib/hadoop-0.17.1-core.jar"/>
    <classpathentry kind="lib" path="lib/hadoop-0.17.1-test.jar"/>
    <classpathentry kind="lib" path="lib/jetty-5.1.4.jar"/>
    <classpathentry kind="lib" path="lib/jruby-complete-1.1.2.jar"/>

</classpath>

to summarize the problem :
I recompiled hbase with JDK 6.0. the conflict is probably with the hadoop
0.17.1 (jdk 5.0) jars that are supplied with 
hbase.

What is your operating system?  What is your JVM?  Did you do 'ant clean 
jar test'?

Can I see the full stacktrace?
