Unable to get service bag for class ...
Regular Member Beiträge: 112 Beitrittsdatum: 22.08.12 Neueste Beiträge
Hello guys
When I start my tomcat my modules doesn't start properly. There is the following error-message:
It looks like the module can't resolve the dependencies. I use one of my modules in the other ones. I only do: compile project("project.name")
Is there something else I can do to maybe say which module needs to be started first?
The funny thing is, when i started the server I only need to do a refresh [module-id] on the gogo-shell. Then it works.
Thank you
Marco

Hi guys
I created two project to reproduce the behavior, have a look to my comment on https://issues.liferay.com/browse/LPS-68967 or https://issues.liferay.com/browse/LPS-68972
https://github.com/severinrohner/liferay-startup-test-service-wrapper
https://github.com/severinrohner/liferay-startup-test-postindexer-hook
I also try to add the ranking property, without any success:
Does anyone have a idea how this could be solved?
Thanks for your help.
Cheers Severin

Hi, When the server is staring, the dependencies for the service wrapper cannot be found, thats why is throwing this error. So when you deploy again the service wrapper (once the server is up), the dependencies (your own modules) are deployed and your service wrapper will work.
To fix that remember that we don't call the xxxxLocalServiceUtil class in the services, we need to call the service directly, so for custom modules you need to specify the xxxxLocalService class like in MentionsBlogsEntryServiceWrapper.java.
Now your service wrapper will handle its own dependencies, and you can use _blogsEntryLocalService to access the service.

@Reference(unbind = "-")
protected void setBlogsEntryLocalService(
BlogsEntryLocalService blogsEntryLocalService) {
_blogsEntryLocalService = blogsEntryLocalService;
}
private BlogsEntryLocalService _blogsEntryLocalService;

Hi Erick
Thanks for your answer.
Did you test my POC on Github?
https://github.com/severinrohner/liferay-startup-test-service-wrapper
https://github.com/severinrohner/liferay-startup-test-postindexer-hook
In this hooks I used the service as you mention already. But it don't work.
If you redeploy or refresh (on the gogo shell) the hook, everything is fine. But this is not okay for a productive server!

Hi Erick!
I'm having the exact same problem. I want to log when someone creates or updates a Web Content. I created a Service Wrapper which overrides the the addArticle and updateArticle methods of JournalArticleServiceWrapper.
Unfortunately when restarting Liferay server, I get the same error Unable to get service bag for class...
Can you please explain your solution for this problem? Thank you very much!

Hi!
I found out that all we need to do is actually just paste the so called "methodThatNoOneCalls" (or call it anything else) with it's reference tag altogether to the end of your custom class just as stated here. I do not really know what happens under the hood, but I got the desired functionality and no more errors or manual restarts.
Here's the code snippet again, I called it serviceSetter by it's functionality:

Liferay Master Beiträge: 753 Beitrittsdatum: 09.01.14 Neueste BeiträgeIt is necessary to add a reference to the service that you are wrapping.
For example, if you are wrapping JournalArticleLocalService, in the JournalArticleLocalServiceOverride class, you have to add:
@Reference
protected JournalArticleLocalService journalArticleLocalService;
in order to declare that your wrapper module depends in that service to be successfully loaded before starting the wrapper.
For more information see the attached journal-override.zip in the LPS-68972 ticket
About the indexer post processor problems during the startup, there is another issue where this problem was solved, see: LPS-72567
