ERROR [BotsManager] - ChatBotFactory service not found in jar

[Rajnish@49]

Hello All,

I am creating a ChatBot using NetBeans 11.1. I am getting this error in DMS while loading of Bot.
ERROR [BotsManager] - ChatBotFactory service not found in jar  AmazonLexRestAccess_V1-1-jar-with-dependencies.jar
ERROR [BotsManager] - Failed to load bot plugin from: AmazonLexRestAccess_V1-1-jar-with-dependencies.jar

Below is the code:-

AmazonLexRestAccess_V1.java

Did you add all your referenced libraries?

[Rajnish@49]

Thanks Kubig...

I am very new to netBeans. so apologies...


While i Clean & Build. Only one Jar file is getting generated. And place the same in bots-repo.
Could you please help where  would need to add those libraries?


I have added reference in my code and pom.xml as well.

import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.AWSStaticCredentialsProvider;
import com.amazonaws.auth.BasicAWSCredentials;
import com.amazonaws.regions.Regions;
import com.amazonaws.services.lexruntime.AmazonLexRuntime;
import com.amazonaws.services.lexruntime.AmazonLexRuntimeClientBuilder;
import com.amazonaws.services.lexruntime.model.PostTextRequest;
import com.amazonaws.services.lexruntime.model.PostTextResult;

[quote]If your bot needs to use 3rd party libraries, you have the option to use maven-assembly-plugin and these libraries will be included into the resulting JAR file.[/quote]

[Rajnish@49]

I am using maven-assembly-plugin to generate one jar file with all dependencies. DMS>>BGS throws error
2020-06-16T19:29:04,324 Std 45302 (CBP.platform) ERROR [BotsManager] - ChatBotFactory service not found in jar: LexV2-1.0-SNAPSHOT-jar-with-dependencies.jar

Check the references at NetBeans. You must add that jar into the lib

Finally I was able to figure out the problem with Help of Genesys. We would need to generate Jar files as build with dependencies  and using below build properties in pom.xml and used ChatBot API of DMS version=9.1.003.12
