Add new methods to standard services

[Jan Bub, modificado 12 Anos atrás.]

Hey,

after working with liferay a few month, I now want to adapt the DocumentLibrary with a protocol. Therefor I need to create some new methods to an existing service. But I have no idea how to realise it. I know that i can override existing methods with hook, but how to add new methods?

Hope you can help me.

The right way to do that is create another service like ExtDocumentLibrary and call from it the original DocumentLibrary.

Thanks for your help. Ok, sounds simple to me but I have more questions.
ServiceBuilder sais I have not to build the Service with ext-Plugin but with hook or standard portlet. How can I make my Service usable portalwide to use it in the ext-Plugin.

I exported now a service.jar from hook plugin an put it in the ext-plugin. It's now in the folder /ext-lib/global. But nothing happens. Always i want to use MyLocalServiceUtil I get an error message: "can not resovle....". Any ideas?

Im still fighting.

I tried to fix the Bug like explained in this thread.

- I loaded the files
- put it into the portal-impl.jar of tomcat
- started all new
- rebuild the service and put it in my ext-plugin/docroot/WEB-INF/ext-lib/global

But I still get the error message:

java.lang.NullPointerException
                   at. de.test.liferay.portlet.service.[b]DLLogEntryLocalServiceClp.<init>(DLLogEntryLocalService.java:568)[/b]

....
</init>

I use Liferay 6.06. CE.

ServiceBuilder say that services are deprecated in ext.

That's means that 'developer have to stop for a while and think if he really need to write service in ext or there are valid alternative using hook or portlets'.

To reach you goal you have to write service in ext. So you have:

• to create the service.xml (for example ext-impl/src/com/ext/portal/service.xml)
• change "build.xml" inside you ext plugins with the following code

    <property name="ext.impl.src" value="docroot/WEB-INF/ext-impl/src" />

    <target name="build-service-portal">
        <property name="service.file" value="${ext.impl.src}/com/ext/portal/service.xml" />
        <antcall target="build-service" />
    </target>

    <target name="build-services">
        <antcall target="build-service-portal" />
    </target>

Now you are able to invoke "ant build-services"

Hey Jan,

For some reason Service Builder is not picking up the modifications of your EXT plugin. If you follow the steps of the thread you will succeed!
