Talend Component Kit InputComponent not visible in studio 7.0.1

Anonymous — Fri, 02 Jan 2026 14:45:42 GMT

Hello,

I developed an output component with the talend component kit and this works great!

So I started developing an input component as well, but then run into following problem:

in workspace log it says:

java.lang.NoClassDefFoundError: org/talend/sdk/component/api/service/record/RecordBuilderFactory

org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Tomcat].StandardHost[localhost].[]]

In another post some say that when studio start it should start the component-server and http://localhost:8080/ should give a response.

With my studio 7.0.1 this is not the case.

When I do mvn talend-component:web then http://localhost:8080 is accesible and I see my component listed there. Now with server started and I start the studio, my inputcomponent becomes visible.

Is there any way to start the server from studio, so I can see my component?

Thanx lot.

Hello,

Record support was added in the coming release of the studio and not in 7.0 which uses 1.0 version of the framework.

Replace RecordBuilderFactory by JsonBuilderfactory and Record by JsonObject for older versions.
