---------------------------------------------------------------
[~jim.ma] [~s.frings74] Can you please let me know what is the purpose of using
@ApplicationScoped and @webservice both?
The reason is *@Application* is responsible for initializing CDI/weld that's why
multiple instances are creating on the server start. One instance is creating for web
services and another for CDI/Weld. Yes, after calling SoapService it should create only
one instance but on server start, the startup method has been executing two times because
as I explain above Test application is initializing for both CDI and web services.
You didn't face this issue in apache because it doesn't have CDI/weld.
Thanks

Yes, after calling SoapService it should create only one instance. Currently, it is
creating two instances.
Wildfly creates to many instances of all web service classes

Key: WFLY-11999
URL: https://issues.redhat.com/browse/WFLY-11999
Project: WildFly
Issue Type: Bug
Components: Web Services
Affects Versions: 8.0.0.Final, 16.0.0.Final, 19.0.0.Final
Environment: Ubuntu 18.10 64bit, Open JDK 8 or Open JDK 11
Reporter: Stefan Frings
Assignee: Parul Sharma
Priority: Minor
Attachments: Test-1.0-SNAPSHOT.war, Test.zip, standalone.xml
1) My @Webservice classes are all constructed multiple times (3x - 4x) but I expected
only one instance.
2) Only the second instance receives a call to the observer method for initialization. I
expect that this method is called in each instance.
The issue can be reproduced with the attached minimum project on Wildfly 8 with JDK 8 as
well as Wildfly 16 with JDK 11.
Complete source code of the whole application:
{code}
package com.mvneco.test;
import javax.enterprise.context.ApplicationScoped;
import javax.enterprise.context.Initialized;
import javax.enterprise.event.Observes;
import javax.jws.WebMethod;
import javax.jws.WebService;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
@ApplicationScoped
@WebService
public class SoapService
{
private Log log = LogFactory.getLog(SoapService.class);
public SoapService()
{
log.debug("Init SoapService 1");
}
@WebMethod(exclude = true)
public void init(@Observes @Initialized(ApplicationScoped.class) Object init)
{
log.debug("Init SoapService 2");
}
@WebMethod
public String test(String payload)
{
log.debug("Start test(). payload="+payload);
return "OK";
}
}
{code}
