How to use third party api in AEM
Hi everyone,
I'm new to aem and is still learning based on the training project adobe provided.
I try to create a new servlet so i can upload file to AWS s3 bucket, but it returns build error and i don't know how to solve it so really prefer some help.
build error message:
Here is what i added into the pom file.
pom.xml
<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk-osgi</artifactId>
<version>1.12.322</version>
</dependency>
core/pom.xml
<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk-osgi</artifactId>
</dependency>
I also download the newest aws-java-sdk-osgi jar file and installed it through web console.But the status is installed and when i try to start the bundle it returns the error below.
error log:
[FelixLogListener]
LogService.org.apache.felix.http.jetty Bundles: Cannot start (org.apache.felix.log.LogException: org.osgi.framework.BundleException: Unable to resolve com.amazonaws.aws-java-sdk-osgi [586](R 586.0): missing requirement [com.amazonaws.aws-java-sdk-osgi [586](R 586.0)] osgi.wiring.package; (&(osgi.wiring.package=com.fasterxml.jackson.dataformat.cbor)(version>=2.12.0)(!(version>=3.0.0))) Unresolved requirements: [[com.amazonaws.aws-java-sdk-osgi [586](R 586.0)] osgi.wiring.package; (&(osgi.wiring.package=com.fasterxml.jackson.dataformat.cbor)(version>=2.12.0)(!(version>=3.0.0)))])

Sorry for interupting you again.
After several changes finally the build successed.
What i've done is i deleted the in-active aws-java-sdk-osgi jar file and add the description below into the core/pom.xml file.
-conditionalpackage: com.amazonaws.aws-java-sdk-osgi.*
-includeresource: @aws-java-sdk-osgi-1.12.322.jar!/
Now the project is in active state but when i made the request to send the file it shows 404 error and i don't know how i can fix it.Could you help me with that?
