I am using AWS SDK to upload files to S3 bucket when set java classpath to "aws-java-sdk-1.10.49.jar", the program works fine, but when replacing jar file to a later version "aws-java-sdk-1.11.35.jar", I get an exception "AmazonServiceException class not found as below."

any help?
here we have three possible problems:
A simple example of NoClassDefFoundError is class belongs to a missing JAR file or JAR was not added into classpath or sometimes jar's name has been changed by someone like in my case one of my colleagues has changed tibco.jar into tibco_v3.jar and the program is failing with java.lang.NoClassDefFoundError and I were wondering what's wrong.
The class is not in Classpath, there is no sure shot way of knowing it but many times you can just have a look to print System.getproperty("java.classpath") and it will print the classpath from there you can at least get an idea of your actual runtime classpath.
Just try to run with explicitly -classpath option with the classpath you think will work and if it's working then it's a sure short sign that someone is overriding java classpath.

we are struggling here with a java.lang.NoClassDefFoundError that makes no sense.
The same WAR file runs perfectly in the server B, but throws a java.lang.NoClassDefFoundError on server A.
Configurations are:
Server A (throws Exception):
OS:

The WAR file runs perfectly on server B but throws the exception on server A.
We inspected the ~/WEB-INF/lib/ folder under tomcat, and the necessary dependency (clojure-1.9.0.jar) is there and is consistent. On a desperate action, we have even tried to replace the jar file for a newer one manually, and it did not work.
From Why am I getting a NoClassDefFoundError in Java? :
java.lang.NoClassDefFoundError This exception indicates that the JVM
looked in its internal class definition data structure for the
definition of a class and did not find it. This is different than
saying that it could not be loaded from the classpath. Usually this
indicates that we previously attempted to load a class from the
classpath, but it failed for some reason
Please advise!

It looks like Tomcat 8.5.50 contains a bunch of regression fixes in Catalina with resource loading which may be affecting the loading of Clojure source files. Suggest either downgrading to same as the working one or upgrading to 8.5.50.

I am suspecting the guide is placing the jar at incorrect path, in previous version ESB 5.0.0, the path is in \repository\components\lib
as given by
https://docs.wso2.com/display/ESB500/Quick+Start+Guide
The right path is EI_HOME\lib . When you see "starting polling event receivers" and the error does not appear,it works. Then you can go on. :)
Try putting this version of snappy-java to lib.
http://mvnrepository.com/artifact/org.xerial.snappy/snappy-java/1.1.1.7
Make sure you remove the old version from both lib and dropins directories.
I am learning Hadoop using the Hadoop for Dummies. I have successfully run thr first steps like installation, creating HDFS and storing Data, running Pig scripts etc.
I have created the FlightsByCarries.jar File.
When I run the code as given in the book, I am getting an error:

Could someone please help me correct this?
it is because your compiler is not getting your main method in the jar FlightsByCarrier. may be you haven't copy the file to hdfs or your file path is not appropriate...check once..and then try
You JAR file is unable to locate the main class name, if you are using any package name in your main class then specify complete name along with package while running the program.
Ex:
hadoop jar FlightsByCarrier.jar com.dev.FlightsByCarrier /input /output
You can also include main class while creating JAR file.
While creating a JAR file after selecting the path then click next --> asks for selecting main class --> browse the name and select --> click OK
Run the command without class name in this case.
hadoop jar FlightsByCarrier.jar /input /output
Hope this solves your problem.
On a completely fresh install of Developer Studio 3.6 (not the plugin) I have created a very simple ESB config project and tried to create a car from the pom editor (using the button in the top right hand corner (as per doc). I get a failure message in the UI "an error occurred while creating the carbon archive file. For more details view the log". The log just shows "java.io.FileNotFoundException: C:\wso2workspace\AthenaHRInterfaceApplication\target\AthenaHRInterfaceApplication_0.1.car (The system cannot find the file specified)".
If I view the target directory as I do this, one can see the file created halfway through the process (i.e. when selecting which directory to save .car file to), but then on completion (ie. OK button), the error is displayed and the file size of .car file goes to 0kb
This is really frustrating and doesn't seem to make any sense. I did get this to work (not with this project) before, but this one just doesn't want to play ball. I can get the car file to be generated external to Dev Studio through maven, but then it isn't deployable from within Studio and appears to be affected by the above error in any case.
Any suggestions to where I may be going wrong?

is this a bug - it looks like it. Happens with a fresh install of DS and new project.
Not that anyone appears to be following this other than the on comments on java version, but for the sake of completeness, I will keep adding to this thread.
It appears that the error was being caused by me selecting the location of the 'target' directory, I suspect that behind the scenes DS is using the same location (as in maven) which is trying to write to the same directory with the same file name which is causing the file not found exception. Saving to a different directory appears to at least get past this error. However, the new issue I have is that Registry Resources aren't being included in the resultant .car file using the button at the top right hand corner of the Composite Application POM editor. If I mvn install (from either command line or from Run(ing) the pom within DS, the correct .car file is generated.
I think I should create another thread with this specific issue and answer this one myself.
Views?
Following the instructions in http://en.wikibooks.org/wiki/Compojure/Getting_Started, I:
downloaded http://github.com/weavejester/compojure/tarball/0.3.2
extracted to ~/compojure
chdir to there
changed permission to executable
run ant deps
ant
run export CLASSPATH=~/compojure/compojure.jar
created compojure shell script
Clojure source file
chdir to there
run ./compojure hello.clj
Then, I got:
