Getting Started Examples

Solace Messaging API for Java (JCSMP)

The "Getting Started" tutorials will get you up to speed and sending messages with Solace technology as quickly as possible. There are three ways you can get started:

• Follow these instructions to quickly spin up a cloud-based Solace messaging service for your applications.
• Follow these instructions to start the Solace VMR in leading Clouds, Container Platforms or Hypervisors. The tutorials outline where to download and how to install the Solace VMR.
• If your company has Solace message routers deployed, contact your middleware team to obtain the host name or IP address of a Solace message router to test against, a username and password to access it, and a VPN in which you can produce and consume messages.

Contents

This repository contains code and matching tutorial walk throughs for five different basic Solace messaging patterns. For a nice introduction to the Solace API and associated tutorials, check out the tutorials home page.

See the individual tutorials for details:

• Publish/Subscribe: Learn how to set up pub/sub messaging on a Solace VMR.
• Persistence: Learn how to set up persistence for guaranteed delivery.
• Request/Reply: Learn how to set up request/reply messaging.
• Confirmed Delivery: Learn how to confirm that your messages are received by a Solace message router.
• Topic to Queue Mapping: Learn how to map existing topics to Solace queues.

Prerequisites

This tutorial requires the Solace Java API library. Download the Java API library to your computer from here.

Build the Samples

Just clone and build. For example:

1. clone this GitHub repository

git clone https://github.com/SolaceSamples/solace-samples-java
cd solace-samples-java

2. ./gradlew assemble

Running the Samples

To try individual samples, build the project from source and then run samples like the following:

./build/staged/bin/topicPublisher <msg_backbone_ip:port>

The individual tutorials linked above provide full details which can walk you through the samples, what they do, and how to correctly run them to explore Solace messaging.

Exploring the Samples

Setting up your preferred IDE

Using a modern Java IDE provides cool productivity features like auto-completion, on-the-fly compilation, assisted refactoring and debugging which can be useful when you're exploring the samples and even modifying the samples. Follow the steps below for your preferred IDE.

Using Eclipse

To generate Eclipse metadata (.classpath and .project files), do the following:

./gradlew eclipse

Once complete, you may then import the projects into Eclipse as usual:

File -> Import -> Existing projects into workspace

Browse to the 'solace-samples-java' root directory. All projects should import free of errors.

Using IntelliJ IDEA

To generate IDEA metadata (.iml and .ipr files), do the following:

./gradlew idea
