Adding /hm/vineetg/jdk1.6.0_03/bin to classpath is wrong/not needed.However, you can see "java.lang.ClassNotFoundException: java.net.URI" in there. So "URI" class, a part of the JDK/JRE cannot be found. Something there smells like a problem with your java installation, not just a pure classpath issue. Can't tell without looking.Otis -- Sematext -- http://sematext.com/ -- Lucene - Solr - Nutch ----- Original Message ----From: Vineet Garg To: [email protected] Sent: Thursday, May 8, 2008 12:18:05 AM Subject: Re: Nutch Exception Hi, I am using jdk1.6.0_03. JAVA_HOME is /hm/vineetg/jdk1.6.0_03/I have not set the class path. The code is in the same dir which contains the hadoop and nutch jar files. If i set class path to /hm/vineetg/jdk1.6.0_03/bin and compile code by following command(from the same dir containing code and hadoop, nutch classes):$ javac Test.javaThen it does not pick up hadoop and nutch classes and throw errors. So I had to unset the classpath. After that code is compiled successfully but throws exception when i try to run it.Vineet [EMAIL PROTECTED] wrote:Vineet, This looks like a JVM/CLASSPATH problem...Which JVM are you using, is your CLASSPATH correct, what's in JAVA_HOME?Otis -- Sematext -- http://sematext.com/ -- Lucene - Solr - Nutch ----- Original Message ----From: Vineet Garg To: [email protected] Sent: Wednesday, May 7, 2008 2:24:03 AM Subject: Nutch Exception Hi,I have crawled and indexed the local filesystem by using nutch 0.9.
