java.lang.NoClassDefFoundError: Could not initialize class com.amazonaws.ClientConfiguration

Question

Using this bundle - aws-java-sdk-osgi-1.11.26.jar in OSGI Server

Below Error is thrown when this is executed AmazonS3 s3 = new AmazonS3Client( credentials );

java.lang.NoClassDefFoundError: Could not initialize class com.amazonaws.ClientConfiguration
        at com.amazonaws.ClientConfigurationFactory.getDefaultConfig(ClientConfigurationFactory.java:46)
        at com.amazonaws.ClientConfigurationFactory.getConfig(ClientConfigurationFactory.java:36)
        at com.amazonaws.services.s3.AmazonS3Client.<init>(AmazonS3Client.java:440)

Any solution to fix this?

Solution 1

Thanks for all suggestions

The ClientConfiguration of aws-java-sdk-osgi-1.11.26.jar is dependent of Jackson-databind.jar Jackson-databind.jar is dependent on Jackson-core.jar So it is not able to initialize ClientConfiguration.

Added Import-Package importing all from jackson-core-osgi.jar in Manifest of Jackson-databind-osgi.jar

Then the issue is resolved

Note: All dependent jars are converted to OSGI jars and deployed

Solution 2

Well, make sure that aws-java-sdk-osgi-1.11.26.jar is present on your classpath, because the class itself is present in the jar. I've just downloaded the jar.
