Hello Eli.

There isn’t a clear advantage, considering the requirement you describe in 2 I recommend you use the Liferay Service Builder. It will take care of your table access concern for you. See the service builder Wiki on the Liferay website for more info.

Regards,
Bert

Hi
thanks for the excellent articles…. I was able to make all of them work. Re: creating and exposing servcies without using service builder or ext.

Two questions:
1) what advantages do you see with this method, over using service-builder or ext? ( i have to explain to my dept why i chose this)
2) i didn’t see in these examples, how to access underlying tables. I have added a couple of tables in the Liferay database, and I need to expose them with basic CRUD operations. and as a follow up to this question…. how to, using hibernate rather than straight JDBC.

thank you in advance for any response,
–Eli

Hi there,

I have tryed following your instructions but i allways get a NullPointerException when deploying the portlet:

at com.liferay.portal.security.permission.ResourceActionsUtil._readActionKeys(ResourceActionsUtil.java:921)
at com.liferay.portal.security.permission.ResourceActionsUtil._readGuestUnsupportedActions(ResourceActionsUtil.java:967)
at com.liferay.portal.security.permission.ResourceActionsUtil._readPortletResource(ResourceActionsUtil.java:1101)
at com.liferay.portal.security.permission.ResourceActionsUtil._read(ResourceActionsUtil.java:900)
at com.liferay.portal.security.permission.ResourceActionsUtil._read(ResourceActionsUtil.java:888)
at com.liferay.portal.security.permission.ResourceActionsUtil.read(ResourceActionsUtil.java:428)

To see if i was doing something wrong i downloaded the project, but it seems that its not the portlet described here.

Hello Adolfo,

I am not sure why this error has thrown. I haven’t done any LR 6.0 development myself but I reckon it has something to do with changes in how service work in 6.0.

Mayb you can use the service builder directly to generate your service? See: http://www.liferay.com/community/wiki/-/wiki/Main/Service+Builder

Good luck and let me know if it worked,
Bert

Hi Bert;

Great post, i just upgrade the code of the liferay version to 6.0.5(avoiding portal-kernel), and i try to invoke the service via de portlet the but liferay keeps saying “the service is not set”, and also I cannot see the service listed at http://127.0.0.1:8080/tunnel-web/secure/axis, What do you think could be the cause for this?
