Using LocalServiceUtils in Liferay 7

we are starting our first Liferay 7 project and I already got stuck.

I would like to create a portlet which reads the Data from the DDMContent Table. Luckily there is the DDMContentLocalServiceUtil.

I am struggeling on how to actually use it.

I added it to the build.gradile file like this:

compileOnly group: "com.liferay", name: "com.liferay.dynamic.data.mapping.api", version: "3.1.0"

I added it to the bnd.bnd file like this :

Import-Package: com.liferay.dynamic.data.mapping.api;version=3.1.0

And then I included in my portlet class like this:

@Reference
    public void setContentLocalServiceUtil(DDMContentLocalServiceUtil contentLocalServiceUtil) {
        this.contentLocalServiceUtil = contentLocalServiceUtil;
    }

The portlet compiles and starts to deploy but I never get to the point where I can actually use it because it is never fully deployed. There is no Exception and there is no hint on what I did wrong.

Is my version number correct ? Do I need to add it to the bnd.bnd file ? Who can help me out ?

Best regards,

Daniel

1) You should use 

Import-Package: *

and let BND resolve that for you based on the jar file you are compiling against (the one you have in Gradle's dependencies)

2) Do not import the <Name>LocalServiceUtil classes. Those are not OSGi services. Use <Name>LocalService instead. Those are the interfaces that define the contracts. In your case it should be: 

@Reference
public void setContentLocalService(DDMContentLocalService contentLocalService) {

3) If your bundle still does not start properly, connect to gogo shell (telnet localhost 11311) and check it's status. Use diag command or simply try to manually start it with start <bundleId> and the framework will tell you if something is wrong with it.
