Hello,

I am trying to run standalone wireMock with custom extension (downloaded as jar, https://github.com/opentable/wiremock-body-transformer).

Command: java -jar wiremock-1.57-standalone.jar --extensions com.opentable.extension.BodyTransformer

The question is, where should I put jar with extension to make it visible for wiremock classLoader? Now, I constantly getting class not found exception:

Exception in thread "main" java.lang.ClassNotFoundException: com.opentable.extension.BodyTransformer

The JAR containing your extension also needs to be on the classpath. Unfortunately java won't let you specify a -cp param and a -jar, so you'll need to do something like this:

java -cp <path to your JAR>:wiremock-1.57-standalone.jar com.github.tomakehurst.wiremock.standalone.WireMockServerRunner --extensions com.opentable.extension.BodyTransformer

Ok, so the only option is to run via main class with additional -cp option.

Thank You for immediate response.

Well, actually there's another option which is to build your own fat JAR incorporating WireMock + your extension and running that with -jar. Bit more effort, but shorter command line/more shippable to colleagues etc.

Hey Tom,

I am currently trying to incorporate my ResponseTransformer file with wiremock and create a new jar out of it. How do we make sure while WireMockServer is running, it will pick my ResponseTransformer ?

Do you have any step by step tutorial to set that up? If yes, please share, I can trace back or restart my work using that tutorial.

Bikram
