Azure SDK for Java - IllegalStateException for missing HttpClient provider when initializing BlobContainerClient

Question

I'm working on integrating Azure Blob Storage into a Java application using the Azure SDK. When initializing the BlobContainerClient, I encounter the following error only on the server (not on my local machine):

Caused by: **java.lang.IllegalStateException**: A request was made to load the default HttpClient provider but one could not be found on the classpath. If you are using a dependency manager, consider including a dependency on azure-core-http-netty or azure-core-http-okhttp. Depending on your existing dependencies, you have the choice of Netty or OkHttp implementations. Additionally, refer to https://aka.ms/azsdk/java/docs/custom-httpclient to learn about writing your own implementation.

    at com.azure.core.implementation.http.HttpClientProviders.createInstance(HttpClientProviders.java:37)
    at com.azure.core.http.HttpClient.createDefault(HttpClient.java:27)
    at com.azure.core.http.HttpPipelineBuilder.build(HttpPipelineBuilder.java:60)
    at com.azure.storage.blob.implementation.util.BuilderHelper.buildPipeline(BuilderHelper.java:110)
    at com.azure.storage.blob.BlobServiceClientBuilder.buildAsyncClient(BlobServiceClientBuilder.java:107)
    at com.azure.storage.blob.BlobServiceClientBuilder.buildClient(BlobServiceClientBuilder.java:84)
    at com.azure.service.impl.AzureBlobAuthService.authenticate(AzureBlobAuthService.java:46)

Here is the relevant part of my code:

 BlobContainerClient containerClient = new BlobContainerClientBuilder()
        .endpoint(config.getSasUrl())
        .containerName(config.getContainerName())
        .buildClient();

Additional Info: I'm using Maven with the following dependency:

<dependency>
    <groupId>com.azure</groupId>
    <artifactId>azure-storage-blob</artifactId>
    <version>12.9.0</version>
</dependency>

could you please clarify what you mean by server, is the app running on an Azure Web App, VM, container or something else? — Harshitha Bathini

The Azure SDK for Java uses a pluggable HTTP client architecture. It doesn't bundle a specific HTTP client implementation by default. Instead, it relies on you to provide one (either Netty or OkHttp) as a dependency in your project. When the SDK tries to create a default HTTP client and can't find either Netty or OkHttp on the classpath, it throws the IllegalStateException.

Solutions Using Netty dependency:

You need to explicitly add azure-core-http-netty as a dependency to your project. Choose one based on your project's existing dependencies and preferences.

Maven dependency:



<dependency>
    <groupId>com.azure</groupId>
    <artifactId>azure-core-http-netty</artifactId>
    <version>1.13.8</version> <!-- Use the latest version -->
</dependency>
