Java Tutorial AWS SDK Sample Skipped Classes

Question

After getting started with the AWS SDK tutorial for Java , to run the AwsConsoleApp sample:

 java -cp .:/Users/marius/Dev/aws-java-sdk-1.3.8/lib/aws-java-sdk-1.3.8.jar AwsConsoleApp 

I get the following issues:

 =========================================== Welcome to the AWS Java SDK! =========================================== Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory at com.amazonaws.util.VersionInfoUtils.<clinit>(VersionInfoUtils.java:41) at com.amazonaws.ClientConfiguration.<clinit>(ClientConfiguration.java:31) at com.amazonaws.services.ec2.AmazonEC2Client.<init>(AmazonEC2Client.java:95) at AwsConsoleApp.init(AwsConsoleApp.java:93) at AwsConsoleApp.main(AwsConsoleApp.java:105) Caused by: java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) ... 5 more 

The same full SDK that was loaded at compile time at compile time is also indicated at runtime, so I cannot figure out what is missing.

Answer 1

Among the SDK prerequisites :

Requires Apache Commons ( Codec , HTTP client and log ) third-party packages that are included in the third-party SDK directory.

so I just added them to my .bashrc :

 # Apache Commons Logging export CLASSPATH=$CLASSPATH:/Users/marius/Dev/aws-java-sdk-1.3.8/third-party/commons-logging-1.1.1/* # Apache Commons HTTP Client export CLASSPATH=$CLASSPATH:/Users/marius/Dev/aws-java-sdk-1.3.8/third-party/httpcomponents-client-4.1.1/* # Apache Commons Codec export CLASSPATH=$CLASSPATH:/Users/marius/Dev/aws-java-sdk-1.3.8/third-party/commons-codec-1.3/*

On Windows, add these paths to your CLASSPATH system

 C:\aws-java-sdk-1.3.21.1\lib\aws-java-sdk-1.3.21.1.jar; C:\aws-java-sdk-1.3.21.1\third-party\commons-logging-1.1.1\commons-logging-1.1.1.jar; C:\aws-java-sdk-1.3.21.1\third-party\commons-codec-1.3\commons-codec-1.3.jar; C:\aws-java-sdk-1.3.21.1\third-party\httpcomponents-client-4.1.1\httpclient-4.1.1.jar; C:\aws-java-sdk-1.3.21.1\third-party\httpcomponents-client-4.1.1\httpcore-4.1.jar 

then be sure to start with a new cmd prompt window.
