Thanks for the response. I am not getting you. Which path you are
talking about?

Try prefixing that path with file:///.....
Now that you got your Java working you are getting into Hadoop land (not
really Nutch) with that class you pasted.

I have resolved this problem also. Now it is throwing following error:
Exception in thread "main" java.io.IOException: No FileSystem for
scheme: file

Am i missing something??

Hi,
Yes there was some problem with Java installation. After resolving
that problem it is throwing following exception now:
Exception in thread "main" java.lang.NoClassDefFoundError:

org.apache.hadoop.conf.Configuration.(Configuration.java:73)

org.apache.nutch.util.NutchConfiguration.create(NutchConfiguration.java:51)

Any idea why it is throwing this exception?

I suggest you start Nutch/Hadoop and observe what classpath it uses
and then mimic that.
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.

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.java
Then 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,
This looks like a JVM/CLASSPATH problem...
Which JVM are you using, is your CLASSPATH correct, what's in
JAVA_HOME?

Subject: Nutch Exception
Hi,
I have crawled and indexed the local filesystem by using nutch
0.9. Then i tried to run the following code just to test the nutch
search:
import org.apache.nutch.searcher.*;
import org.apache.nutch.util.*;
import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.fs.Path;
import java.io.*;
class Test{
public static void main(String arg[])throws IOException{
IndexSearcher IS;
Configuration conf;
Path oPath = new Path("/hm/vineetg/nutch-0.9/crawl_test");
conf = NutchConfiguration.create();
IS = new IndexSearcher(oPath, conf);
//Construct query
Query newQuery = Query.parse("search_query", conf);
Hits hits = IS.search(newQuery, 300, null, null, false);
int TotalResults = (int)hits.getTotal();
for (int iCounter = 0; iCounter < TotalResults; iCounter++)
{
Hit hit = hits.getHit(iCounter);
HitDetails details = IS.getDetails(hit);
String sTitle = details.getValue("title");
String sURL = details.getValue("url");
}
}
}
But it is throwing following exception:
