[Mr Nissi, modificado 12 Anos atrás.]

Hi, i am new to liferay and in using service Builder.

Really doesn't matter how the service.xml file looks.
i Got the same error for a lot of different examples
my service folder and sql folders are created but with not classes or codes
In addition i Got the following error while trying to build a new service
