@antonioluzzi AFAIK you can't deploy a standalone MSF4J application in WSO2 EI. MSF4J has another mode called deployable-jar mode. If you want to deploy an MSF4K microservice, you have to use that mode.
Please refer the sample in https://github.com/wso2/msf4j/tree/master/samples/stockquote/deployable-jar

[antonioluzzi]

The fat version works fine, instead deployable version no :-(

@antonioluzzi This is a checkstyle error. Can you try disabling checkstyle and build
e.g. "-Dcheckstyle.skip=true"

[antonioluzzi]

thanks to help me.
I have succeful compiled my project : mvn install -Dcheckstyle.skip=true -Dfindbugs.skip=true
but my rest service doesn't start, maybe there are some missing dependencies.
My rest service use external api (apache cmis). In my standalone version, it works fine, instead of the deployable version no. I m new in ms4j and wso2ei. In my case where do I have to put all the dependencies and configuration file (application.properties)?
Regards
Antonio

@antonioluzzi You can put all your dependencies in the pom.xml including relevant msf4j dependencies

[antonioluzzi]

Pardon me, but I don't understand.
Can you advise me to take a look a practical example?

[antonioluzzi]

Can you suggest to me an example of a deployable project where I can import spring?
