QUESTION
I am writing a Payara Micro web application that should connect to a database as defined in persistence.xml
. The database it should connect to is a file on my local machine and at the time of project startup, it does not exist. To my understanding, H2 should create a file for the database on first connect.
The persistence.xml
looks like:
ANSWER
Answered 2021-Mar-09 at 09:54The problem is that you're using transaction-type="JTA"
, which means that the datasource is retrieved from Payara Micro and not created by Hibernate based on the properties you specified.
You should change transaction-type="JTA"
to transaction-type="RESOURCE_LOCAL"
. That should fix it and behave as you expect.
What's happening now is that Hibernate asks for a datasource from Payara Micro and ignores the hibernate.connection
properties. You didn't specify any datasource JNDI name (e.g. with the hibernate.connection.datasource
), therefore it will retrieve the default datasource. The default datasource in Payara Micro is for an H2 database stored in a temporary directory.
QUESTION
I'm migrating a WAR application from PayaraServer to Payara Micro to reduce RAM usage.
I just realise that @PreDestroy on EJBs are not called when stopping the instance with CTRL+C.
Is there a correct way to close the payaramicro instance properly as I'd like to execute some operations.
Thanks for your answers!
Or which services in Payara Server to deactivate to use as much as RAM as PayaraMicro?
I'm using the version 5.183, and I also tried the 5.192.
...ANSWER
Answered 2020-Feb-24 at 21:19Which kind of EJB did you use? In my opinion it should work on @Singleton
and @Stateless
. I am not sure how the other EJBs are supported by Payara Micro.
However, since Payara Micro supports the Java EE Web Profile and you are using a web application anyway, I would suggest to use a @WebListener
to get notified of lifecycle events.
It could be implemented as follows:

Answered 2018-Oct-31 at 01:20It looks like you had the webapp folder in the wrong place (it should be under main, not under main/resources) and you didn't have a web.xml which enables the faces servlet.
I created a PR for you which builds a working app. I also changed the packaging to war as I'm not so familiar with the uberjar packaging. HTH!
QUESTION
The App is a hello world created with the NetBeans Payara Micro plugin: it contains nothing but an index.html and a main class that writes "hello world".
I added a dependency in the POM to check that external libraries are handled correctly. I don't want an uber jar so my POM places the libs in a /lib
folder inside the /target
folder
I build the app in NetBeans then open a shell in the /target
folder, deploying with:
ANSWER
Answered 2018-Oct-08 at 09:05You need to remove the addClasspath
configuration in your pom.xml file, in the WAR plugin. Then your command with --addLibs
will work.
Your current configuration in the MANIFEST inside the WAR instructs to search for the JARs in the folder where the WAR is located. This doesn't work with Payara Micro, because the WAR file is first copied into a temporary folder before it's deployed. Since the JARs are not in that folder, they're not found.
You need to build a WAR file without classpath specified in MANIFEST and then just use the --addLibs
argument to supply additional JARs.
So if you just remove the following from your pom.xml all should work:
true
lib/
net.clementlevallois.qof.back.email.Controller
QUESTION
I am running a payara micro server and having some difficulties serializing an object.
The root object has a child object which is either of type A
or B extends A
. The issue is that it always serialized into json as if it was of type A
, i.e. no properties that are in the type B
are being serialized.
I have checked that the object is correct right after returning the Response
object.

ANSWER
Answered 2018-Jun-21 at 09:01Easiest solution is to use Jackson. MOXy is based off JAXB rules, which can get very complicated in some situations (this includes working with inheritance). Jackson just works.
Just add the Jackson dependency (in a provided scope, as Payara already has the dependency) and register the JacksonFeature
with the application.
QUESTION
I would like to know if its possible for java enterprise application to deploy another application to payara server. I found something in the Documentation.
...ANSWER
Answered 2018-Apr-25 at 12:02There's no official way to do this in Payara Server although it's possible to do it.
There's GlassFish API which can be used from a deployed application to deploy other apps. See Deployer Javadoc. Nothing has changed in Payara Server so it should work also with Payara Server.
Another option is to use Cargo project deployer, which also supports Payara Server (using the GlassFish deployer). It also works outside of Payara Server, in any Java SE application, but is more complicated to set up.
Another option is to use the raw REST endpoint provided by the Admin Console, which is used by the asadmin tool and Cargo Deployer. You wouldn't need any external dependency but it's not very documented which resource to access. Here's the docs, here's the code of the DeployCommand which describes which parameters it accepts, and here's a path to the deploy endpoint: http://localhost:4848/management/domain/applications/deploy. If you paste the link to a browser, it will give an HTML frontend to test with. If you send a post request with accept type JSON, it will return a response in JSON format (success/failure)
