Rest Interface Issue Using Quarkus

[jeportc82]

Environment Details

• MicroStream Version: 08.01.01-MS-GA
• JDK version: 17
• OS: Mac os
• Used frameworks: Quarkus 3.3.1

Describe the bug

REST Interface does not start.

I'm getting the following error.

Exception in thread "Thread-130" java.lang.NoClassDefFoundError: javax/servlet/Filter

        at spark.embeddedserver.EmbeddedServers.initialize(EmbeddedServers.java:41)
        at spark.Service.lambda$init$2(Service.java:618)

To Reproduce

Add the following maven dependencies

    <dependency>
      <groupId>one.microstream</groupId>
      <artifactId>microstream-quarkus3-extension</artifactId>
      <version>08.01.01-MS-GA</version>
    </dependency>
    <dependency>
        <groupId>one.microstream</groupId>
        <artifactId>microstream-storage-restservice-sparkjava</artifactId>
        <version>08.01.01-MS-GA</version>
    </dependency>

and then execute the following code to start the service

StorageRestService service = StorageRestServiceResolver.resolve(storage);
service.start();

Expected behavior

Rest Interface must be available in the default por 4567.

The NoClassDefFoundError is most likely caused by the missing java EE dependencies required by our rest service implementation. Quarkus already uses the newer Jarkata EE.

Our ‘microstream-storage-restservice-sparkjava’ was implemented to run within plain java applications. Therefore, it brings its own rest framework and webserver (sparkjava). If you like to use the rest-api with Quarkus I’d suggest not using our implementation. Instead, you may consider implementing the required rest api directly using Quarkus only. Doing so should be quite trivial. Please see https://github.com/microstream-one/microstream/discussions/549 for more details.

@jeportc82 it was super easy to implement the REST endpoints "in house" as described in #549 With Quarkus the REST part is super easy and the only thing you will have to do is plug in 2-3 lines of code calling the micsotream adapter
