I was following this tutorial to install JacORB Tutorial. In the last step, when I want to compile it, I got this error
Buildfile: /Users/adm/Downloads/jacorb/build.xml
base-init:

init-javac-jdk:

BUILD FAILED
/Users/adm/Downloads/jacorb/build.xml:21: Unable to find src files. Is this a binary distribution?
But if I try ant in a demo file it builde successfully. I don't have to do the last step in the tutorial ? The second question is how to excute the build file ? after I builded the hello demo, I tried "jaco build" but I got a java exception
jaco build

You likely have the binary distribution of JacORB.
Download the source distribution of JacORB instead. On the JacORB Download page, click the link for Full source code.
Or see https://github.com/JacORB/JacORB/ for the official source code.
I would recommend asking questions about JacORB on the jacorb-developer list (http://www.jacorb.org/contact.html)

I downloaded the confluent package which includes camus jars and I followed the instructions online enter link description here.
Hadoop is properly setup (meaning I can use hadoop fs -ls commands and other hadoop jar commands). However, when i tried to run
hadoop jar confluent-camus-1.0.jar com.linkedin.camus.etl.kafka.CamusJob
I got "main" classNotFound error
Exception in thread "main" java.lang.ClassNotFoundException: com.linkedin.camus.

The the path to the "confluent-camus-1.0.jar" is correct (right under the folder). I didn't start the kafka service, just to try to run it.
Anyone got similar problems?
Thanks.
You should try to inspect your jar file:
jar tvf confluent-camus-1.0.jar | grep com.linkedin.camus.etl.kafka.CamusJob
If you do not find this class, try to find it in other jar, which generated by camus.
After you should add target jar with
hadoop jar confluent-camus-1.0.jar com.linkedin.camus.etl.kafka.CamusJob -libjars {JAR_NAME}
I am having trouble on setting up classpath on Mac. The following is the code I have attempted,
First I exported the jars using terminal
abc-MacBook-Pro:~ abc$ export
CLASSPATH=$CLASSPATH:/Users/abc/Desktop/IR/luceneJar/demo/lucene-demo-4.0.0.jar: export
CLASSPATH=$CLASSPATH:/Users/abc/Desktop/IR/luceneJar/core/lucene-core-4.0.0.jar: export
CLASSPATH=$CLASSPATH:/Users/abc/Desktop/IR/luceneJar/queryparser/lucene-queryparser-4.0.0.jar: export
CLASSPATH=$CLASSPATH:/Users/abc/Desktop/IR/luceneJar/analysis/common/lucene-analyzers-common-4.0.0.jar
Then when I echoed the classpath, following is the result
abc-MacBook-Pro:~ abc$ echo $CLASSPATH
/Users/abc/Desktop/IR/lucene-4.0.0 2/core/lucene-core 4.0.0.jar:
/Users/abc/Desktop/IR/lucene-4.0.0 2/demo/lucene-demo-4.0.0.jar:
/Users/abc/Desktop/IR/luceneJar/analysis/common/lucene-analyzers-common-4.0.0.jar
The error I am having is following when I tried to function the index file
abc-MacBook-Pro:~ abc$ java org.apache.lucene.demo.IndexFiles -docs
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/lucene/demo/IndexFiles

Please let me know about the above error, thank you in advance. I am quite new with Lucene Java.
This is common Java classpath problem, nothing related to lucene (or mac) here.
Try this
1) Create lib folder and move all your lucene jars to lib
- lets say your project has two folders now lib and src, lib has all jars and src has yourJavaFile.java
2) Run below commands for compilation and execution from your src
- javac -cp ".:../lib/*" yourJavaFile.java
- java -cp ".:../lib/*" yourJavaFile
I'm working from this example and I am running into this error after adding log4j, slf4j and bonecp to the project:

In addition to BoneCP and SLF4J, you need to add Google Guava, because BoneCP's requirements page states that it needs to be present. Download guava-*.jar and add it to your classpath the same way you did with SLF4J and BoneCP.
You will need to add those jars to the classpath of your Java process when you run it. For example,
java -classpath lib/log4j.jar;lib/slf4j.jar;lib/bonecp.jar [your_class]
This assumes that the jars are in a dir called lib which is in the directory you execute the Java command from.

Scenario: I am working on my final year project which is to create a website which uses Lucene to search my website and my database. I am working through lucene demos here
http://lucene.apache.org/java/2_3_2/demo.html
which talks about classpath
http://lucene.apache.org/java/2_3_2/demo3.html and a web example
I have created a .bash_profile file in my home directory /Users/philhunter/ which sets my classpaths:
CLASSPATH=${CLASSPATH}:/Users/philhunter/Desktop/COM562_Project/lucene-3.0.3/lucene-core-3.0.3.jar
CLASSPATH=${CLASSPATH}:/Users/philhunter/Desktop/COM562_Project/lucene-3.0.3/lucene-demo-3.0.3.jar
CLASSPATH=${CLASSPATH}:/Users/philhunter/Desktop/COM562_Project/lucene-3.0.3/src/demo/org/apache/lucene/demo
When i try and run the commands it asks on the command line i am getting ClassDefNotFoundError:
Exception in thread "main" java.lang.NoClassDefFoundError: /Users/philhunter/Desktop/COM562_Project/lucene-3/0/3/src/demo/org/apache/lucene/demo/IndexHTML

The command line command is:
java /Users/philhunter/Desktop/COM562_Project/lucene-3.0.3/src/demo/org/apache/lucene/demo/IndexHTML -create -index /Applications/MAMP/htdocs/
which should index my website files. That indexHTML file is a java file in that last classpath directory above. Anyone know why I am getting theat error!?
I think the path you're passing is the problem. Try adding the following to your bash script
cd /Users/philhunter/Desktop/COM562_Project/lucene-3.0.3/src/demo/
java org.apache.lucene.demo.IndexHTML -create -index /Applications/MAMP/htdocs/
The problem is that when you run
java /Users/philhunter/Desktop/COM562_Project/lucene-3.0.3/src/demo/org/apache/lucene/demo/IndexHTML
you are telling java run the class in the package Users.philhunter.Desktop.COM562_Project.lucene-3.0.3.src.demo.org.apache.lucene.demo.

I tried both Google Data API versions 1.35.0 and 1.35.1, and I get the same error in both cases.
Looks like you don't have the collections library in your class path.
It's in the gdata/java/deps directory in the zip file. Include the google-collect-1.0-rc1.jar file in your classpath and you should be fine. (You may also need jsr305.jar - I'm not sure.)
Three little steps:
Download the zip file from
http://www.docjar.com/jar_detail/google-collect-1.0-rc1.jar.html
Extract the zip file
Add the jar to your build path.
