DynamoDB integration with AEM 6.5

[Sai_Krishna_1404]

Hi Adobe Community,

Trying to integrate aws dynamoDB to update records in dynamoDB. we are using awsSDK 2.x version to integrate it, converted aws jar to OSGI jar & resolve the dependencies, but still it throws nullpointer exception on the DynamoDBClient object when called in the OSGI service class. Want to check if anyone had did dynamoDB integration before & help with the steps or help on resolve on instantiation of DynamoDBClient in the service (@reference is not working directly). Thanks in advance!

hi @Sai_Krishna_1404, I don't have experience with DynamoDBClient but I can recommend this:

<!-- https://mvnrepository.com/artifact/org.apache.servicemix.bundles/org.apache.servicemix.bundles.aws-java-sdk2 -->
<dependency>
    <groupId>org.apache.servicemix.bundles</groupId>
    <artifactId>org.apache.servicemix.bundles.aws-java-sdk2</artifactId>
    <version>2.29.6_1</version>
</dependency>

 It's provided by Apache Servicemix-bundles which offers OSGI-fied versions of many famous packages as you can see here.

Thanks for the response @giuseppebag , tried adding this dependency but this doesn't seems to be downloading the OSGI supported version, when I tried to install this version, it is throwing it doesn't have Symbolic bundle name

Please ensure the jar is embedded into the installation package via

filevault-package-maven-plugin

You can use as a reference this code

from here. You can also check how the AEM archetype does it by creating a new temporary project which will leverage this all/pom.xml file.

servicemix jar resolve firing DynamoDBClient, one issue with servicemix aws version is, in my use case I only need DynamoDB SDK only, but this jar had all different package which is not required for my project, & jar size coming up to be more than 500MB, not sure if adobe can provide a solution to generate OSGI Jar SDKs for external dependencies.

[giuseppebag]

Apache provides Servicemix bundles, not Adobe. You can try this approach, but it becomes challenging when there are many dependencies and there are no guarantees of success.
