I have create an EJB program with 2 interfaces, 1 persistente class and 1 stateless class which implement the 2 interfaces (Remote interface and Local interface)
After that I've create a Java Client with 1 class and I add jboss-client.jar to classpath of java client app and jboss-ejb-client.properties files. But when I run the java client it's generate an error.
I need your help to fix it. Thank you.

Run mvn dependency:tree to view the whole dependency tree. You check if you see a problem here.
And try upgrading the maven-plugin version.
I want to use JPA for micronaut. For that I am using io.micronaut.data:micronaut-data-hibernate-jpa:1.0.0.M1 library. Whenever I run my application and hit the endpoint to get the data, I get the following error:
{

}
I tried looking up for errors but I couldn't find one. Attaching my files here. Please help.

Micronaut currently supports only Tomcat JDBC, Apache DBCP2 and Hikari data sources providers out of the box (see https://micronaut-projects.github.io/micronaut-sql/latest/guide/#jdbc).
You can add this line into your build.gradle which adds Tomcat JDBC Data Source provider implementation into your project:
runtime "io.micronaut.configuration:micronaut-jdbc-tomcat"
Or you can choose another implementations like Apache DBCP2:
runtime "io.micronaut.configuration:micronaut-jdbc-dbcp"
Or Hikari:
runtime "io.micronaut.configuration:micronaut-jdbc-hikari"
For nl.topicus:spanner-jdbc data source provider you have to implement your own DatasourceFactory and DatasourceConfiguration for Micronaut because there is no one yet.
You can inspire your self in io.micronaut.configuration:micronaut-jdbc-tomcat. Sources are here: https://github.com/micronaut-projects/micronaut-sql/tree/master/jdbc-tomcat/src/main/java/io/micronaut/configuration/jdbc/tomcat
For example DatasourceFactory can then look like this:
#Factory
public class DatasourceFactory implements AutoCloseable {
private static final Logger LOG = LoggerFactory.getLogger(DatasourceFactory.class);
private List<nl.topicus.jdbc.CloudSpannerDataSource> dataSources = new ArrayList<>(2);
private final DataSourceResolver dataSourceResolver;
/**
* Default constructor.
* #param dataSourceResolver The data source resolver
*/
public DatasourceFactory(#Nullable DataSourceResolver dataSourceResolver) {
this.dataSourceResolver = dataSourceResolver == null ? DataSourceResolver.DEFAULT : dataSourceResolver;
}
/**
* #param datasourceConfiguration A {#link DatasourceConfiguration}
* #return An Apache Tomcat {#link DataSource}
*/
#Context
#EachBean(DatasourceConfiguration.class)
public DataSource dataSource(DatasourceConfiguration datasourceConfiguration) {
nl.topicus.jdbc.CloudSpannerDataSource ds = new nl.topicus.jdbc.CloudSpannerDataSource();
ds.setJdbcUrl(datasourceConfiguration.getJdbcUrl());
...
dataSources.add(ds);
return ds;
}
#Override
#PreDestroy
public void close() {
for (nl.topicus.jdbc.CloudSpannerDataSource dataSource : dataSources) {
try {
dataSource.close();
} catch (Exception e) {
if (LOG.isWarnEnabled()) {
LOG.warn("Error closing data source [" + dataSource + "]: " + e.getMessage(), e);
}
}
}
}
}
Anyway you can still use Google Cloud Spanner DB with Data Source providers like Hikari and Apache DBCP2. For example:
runtime 'nl.topicus:spanner-jdbc:1.1.5'
runtime "io.micronaut.configuration:micronaut-jdbc-hikari"
The first line adds JDBC driver and the second line adds Data Source provider which will use the spanner-jdbc JDBC driver.
It is known that the Google Cloud Spanner uses another dialect than other databases for Hibernate ORM. I think that this dialect is pretty new. Take a look over this repository 1. Maybe it will be useful for you, not necessary for solving your current issue, but giving you some other perspective.
Is it common or acceptable to keep and ejb connection opened while opening and closing other ejb connections or should connections be closed as soon as the client is done with it and a new one opened for subsequent tasks?
I'm currently working on a Swing application that uses EJBs (JBoss AS 7.1.1.final). The application opens an ejb connection (i.e. creates an InitialContext instance) and then uses that InitialContext for common tasks for the as long as the application is left running. There are a number of long running operations where an additional ejb connection (and InitialContext) is created. This connection is used for the single long running process and is then closed.
On JBoss, after about the 40th connection is opened and closed I get the exception shown below.

Is this a bug that is specific to JBoss AS 7.1.1.final?
The problem here was that a single connection was being left open and used as a resource by the main thread of the application and this (for some reason) caused JBoss not to completely de-allocate the other connections. The solution was to get a reference to this connection when it was opened and then close this connection before creating any other new connection and then re-open the connection being used by the main thread as soon as the new connection was created.
I'm coding on Jitsi using Eclipse: I have to use JDBC to connect to MySQL database, so I've imported java.sql.* in my MainFrame class and I've included mysql-connector-java-5.1.18.jar into "Java Build Path" -> "Libraries".
When I run the project, I've this error:

I've created another project separated from Jitsi and I've tested my code following the same procedure (including java.sql.*; , adding the library), but the "new" project works fine and I can connect to my database, Jitsi doesn't.
Source:
import java.sql.*;
public class SQLFirstTime {
public static void main(String[] args) {
try {
Class.forName("com.mysql.jdbc.Driver");
String url = "jdbc:mysql://localhost:3306/cdcol";
Connection con = DriverManager.getConnection(url,"user", "pass");
// ...
con.close();
} catch(SQLException sqlEx) {
System.out.println("Errore SQL");
sqlEx.printStackTrace();
} catch(ClassNotFoundException cnfEx) {
System.out.println("Class NOT FOUND!");
cnfEx.printStackTrace();
}
}
}
Thanks,
also if i'm using Ant to build the project how can I include the JDBC library?
I create an Enterprise Application CustomerApp that also generated two projects CustomerApp-ejb and CustomerApp-war. In the CustomerApp-ejb, I create a SessionBean call CustomerSessionBean.java as below.
package com.customerapp.ejb;
import javax.ejb.Stateless;
import javax.ejb.LocalBean;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
#Stateless
#LocalBean
public class CustomerSessionBean {
#PersistenceContext(unitName = "CustomerApp-ejbPU")
private EntityManager em;
public void persist(Object object) {
em.persist(object);
}
}
Now I can deploy CustomerApp-war just fine. But as soon as I create a Message Driven Bean, I cant deploy CustomerApp-war anymore. When I create NotificationBean.java (message driven bean), In the project destination option, I click add, and have NotificationQueue for the Destination Name and Destination Type is Queue. Below are the code
package com.customerapp.mdb;
import javax.ejb.ActivationConfigProperty;
import javax.ejb.MessageDriven;
import javax.jms.Message;
import javax.jms.MessageListener;
#MessageDriven(mappedName = "jms/NotificationQueue", activationConfig = {
#ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"),
#ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue")
})
public class NotificationBean implements MessageListener {
public NotificationBean() {
}
public void onMessage(Message message) {
}
}
The server log said Message Driven Bean cant be managed bean. Well I did not mean it to be managed bean. I did not have #ManagedBean in the code????
EDIT: Here is the server log

The Exception is DeploymentException: Message Driven Beans can't be Managed Beans
This is a bug in GlassFish 3.0 which is fixed in 3.0.1.
workaround: remove the beans.xml (but this will disable CDI)
real solution: download a promoted build of GlassFish 3.0.1 (the problem is reported as being fixed in version 3.0.1-b9 so any superior version should work)
Below the initial answer:
Where is the MDB located? Did you put it in the CustomerApp-ejb?
What do you mean by Now I can deploy CustomerApp-war just fine? You're supposed to deploy the Enterprise application (CustomerApp).
What do you see in the GlassFish logs when the deployment fails?
