Hi there, Where can I download the latest JAR file that contains IBackendlessService? The project template download does not have this anymore.

Hi @David_Pellecchia

You can download the latest jar in the Cloud Code section → Handlers → Download. Please check there.

Regards,
Marina

TY Marina. But I don’t see Backendless.jar in the download.

This is what I get in the download zip file -

Hi, David.
The approach to using java-sdk was changed. Now we have builds for plain java, coderunner and for android os.

In detail look here: GitHub - Backendless/java-sdk
In short: you need either java-client-sdk or android-client-sdk package from maven repo.
Maven Central Namespace: com.backendless

If you download CodeRunner project from our site, it already contains all the libraries with all dependencies (jar file in lib dir).

David_Pellecchia · June 20, 2023, 1:16pm

TY @oleg-vyalyh. Can you point me to where in your site I can download the CodeRunner project? Also please confirm the correct JDK version we should be using.

oleg-vyalyh · June 20, 2023, 1:55pm

You can download CodeRunner project here:

or

oleg-vyalyh · June 20, 2023, 1:56pm

But I also would like to clarify, why are you asking specifically about backendless.jar.
Is there some problem with code compilation or something else?

p.s. the latest version you may found in releases section on GitHub (the link was in the previous post).

David_Pellecchia · June 23, 2023, 3:59am

Hi Oleg, I will try your suggestions. Regarding Backendless.jar, that is what we have in our class path for the Java cloud code implementation. We need to implement IBackendlessService and backendless.jar used to have that interface.

David_Pellecchia · June 23, 2023, 4:19am

Hi Oleg, I setup maven and added the below dependency - I am running the ‘com.sample.api.DemoService’ straight from your website.

<dependency>
  		<groupId>com.backendless</groupId>
  		<artifactId>java-client-sdk</artifactId>
  		<version>8.0.0-RC1</version>
  	</dependency>

I am able to get a clean compile now.
But when I run CodeRunner.sh, I get the following error (I am using java 17.0.7 2023-04-18 LTS)

The number of the latest stable version you can find here
GitHub - Backendless/java-sdk
If you download project from our site it already contains the latest versions of CodeRunner and java-sdk. Why was it necessary to attach another one with the maven ? Or you deleted the libs dir?
It is not clear for me, what actions you do after downloading the project?
Usually the following steps are enough:

download the project from our site;
put into src dir your code;
build the project;
run ./bin/CodeRunner.sh

oleg-vyalyh · June 23, 2023, 7:40am

Just an advise: you can use annotation @BackendlessService in order to declare your custom class as a backendless service class.

David_Pellecchia · June 23, 2023, 3:46pm

OK I will try re-doing all the steps from within a fresh workspace.
