How to import external SDKs like from aws correctly via maven to use in tjava component? (Use Case: Calculate aws siganture version 4)

[AKizilarslan1702922386]

Hi folks,

I need help for following questions:

• How to import external SDKs like from aws correctly via maven to use in tjava component?
• Do I need to set further dependencies so my job or the JVM find the maven dependency? I am thinking of class- or build-paths by asking this.
• I assume that via maven my job will also work in Talend Cloud. Please correct me if my assumption is not correct.

Use Case: Calculate aws siganture version 4 (with the AWS4Signer-java-class) and create authentication header. Use this auth header afterwards by executing POST-API-request.

Specs: I am using Talend Studio Version 8.0.1 (Data Integration Perspective)

Nice to know: I also tried to compute aws signature by default talend-java-classes (so, without installing external jars) but calculation of sigature seems to be incomplete according API-Response.

I'm happy about every tip and solution suggestion. Thanks!

Hi

You have two ways to load additional JAR files,

• Using tlibraryLoad to load external jar in the job, you can then use the relevant java classes on tJava, tJavaRow or tJavaFlex components.
• Create a user routine and load external jars.

Hi shong, thanks for reply!

Locally on talend Studio I could use external JAR files by using tLibaryLoad.

After publishing into talend cloud I faced other errors (" Exception in thread "main" java.lang.Error: Unresolved compilation problems:"). I did some research and ended up with installing nexus first.
