I am developing an application with Hibernate and Websphere Application Server 8.0.
I have create a datasource in Websphere and it can connect with database successfully.
But from application I am getting following error:
SystemErr R Error creating Session: org.hibernate.service.jndi.JndiException: Unable to lookup JNDI name [java:comp/env/jdbc/OracleDS]
Following is the setup I have done:
Websphere datasource setup:
hibernate.cfg.xml
web.xml
When I try to get sessiofactory, it gives me error:
HibernateUtil.java:
try
{
Configuration configuration = new Configuration().configure();
serviceRegistry = new ServiceRegistryBuilder().applySettings(configuration.getProperties()).buildServiceRegistry();
sessionFactory = configuration.buildSessionFactory(serviceRegistry);
}
catch (HibernateException he)
{
System.err.println("Error creating Session: " + he);
throw new ExceptionInInitializerError(he);
}
Error:

Did you create binding between you reference and JNDI name?
You can do it
either using admin console - Enterprise Application > ApplicationName > Resource references. then select reference and map it to the datasource JNDI name
or using binding file - you need to create ibm-web-bnd.xml file with the following contents:
<resource-ref name="jdbc/OracleDS" binding-name="jdbc/OracleDS" />
In WebSphere you don't need java:comp/env at the hibernate datasource.
So your hibernate.cfg.xml would look like this:
.
.
.
<!-- JNDI Datasource -->
<property name="hibernate.connection.datasource">jdbc/OracleDS</property>
.
.

I'm using hazelcast in my project and want to move hazelcast host:port information into environment variables. Before that I had default configuration that is:
<hazelcast-client xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.hazelcast.com/schema/client-config
http://www.hazelcast.com/schema/client-config/hazelcast-client-config-3.8.xsd"
xmlns="http://www.hazelcast.com/schema/client-config">
<network>
<connection-timeout>3000</connection-timeout>
<connection-attempt-period>1000</connection-attempt-period>
<connection-attempt-limit>259200</connection-attempt-limit>
</network>
</hazelcast-client>
and I've found that there is possibility to add <cluster-members> tag inside <network> to provide custom <address> for hazelcast instances. I've modified my hazelcast.xml file into:
<network>
<cluster-members>
<address>${HAZELCAST_URL}</address>
</cluster-members>
...
But whenever I'm starting my app it shows:
2017-11-10 17:55:45 [service,,,] WARN c.h.c.s.i.ClusterListenerSupport hz.client_0 [dev] [3.8.5] Exception during initial connection to ${HAZELCAST_URL}:5701, exception java.lang.IllegalArgumentException: Can't resolve address: ${HAZELCAST_URL}:5701
2017-11-10 17:55:45 [service,,,] WARN c.h.c.s.i.ClusterListenerSupport hz.client_0 [dev] [3.8.5] Exception during initial connection to ${HAZELCAST_URL}:5702, exception java.lang.IllegalArgumentException: Can't resolve address: ${HAZELCAST_URL}:5702
It means it still tries to connect to default port and variable is not resolved. Is there a way to configure it?
You can pass java.util.Properties into the client config builder. All you need do is build it from Spring's environment.
#Bean
public ClientConfig clientConfig(Environment environment) throws Exception {
Properties properties = new Properties();
String HAZELCAST_URL = "HAZELCAST_URL";
properties.put(HAZELCAST_URL, environment.getProperty(HAZELCAST_URL));
XmlClientConfigBuilder xmlClientConfigBuilder = new XmlClientConfigBuilder("hazelcast-client.xml");
xmlClientConfigBuilder.setProperties(properties);
return xmlClientConfigBuilder.build();
}
#Bean
public HazelcastInstance hazelcastInstance(ClientConfig clientConfig) {
return HazelcastClient.newHazelcastClient(clientConfig);
}
Note, there are more elegant ways to do this, the above is just one solution keeping it as simple as possible
I am migrating a Project which using JBOSS fuse to Spring Boot and I use this code for registry a dynamic DataSource:
PropertyPlaceholderDelegateRegistry reg = (PropertyPlaceholderDelegateRegistry) exchange.getContext().getRegistry();
CompositeRegistry cReg = (CompositeRegistry) reg.getRegistry();
SimpleRegistry simpleReg = new SimpleRegistry();
simpleReg.put(
Messaging.Names.SAM_DATABASE_CONNECTION_KEY.toString() + configuration.getCustomerNumber(),
dataSource);
cReg.addRegistry(simpleReg);
But when i migrated it to Spring boot, it does not work and has this Error:
There's uncaught exception has occured. Exception message:
org.apache.camel.spring.spi.ApplicationContextRegistry cannot be cast to org.apache.camel.impl.CompositeRegistry
Please help!!!
I'm running JBoss 5.1 GA with JDK 1.6 on Linux and trying to call session bean(jar containing this session bean is deployed on jboss server), Now i want to call this session bean from client, but didnt work.
Java Code at client Side
public class CallingJbossSessionBeanFromClient {
/**
* #param args

public static void main(String[] args) throws Exception
{
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");

System.out.println("Called");
}
}
where 'SlsSessionBean/remote' is remote binding of session bean deployed on jboss server.
#Stateless

Plz tell me, am i on the right way to call sesion bean from client java class?
I have spent hours looking for solution on Google. However I cannot seem to find anything that holds the hand..try to be more clear, i'm in lack of ideas in this problem, even it sounds like a classic
Plz suggest solution
The solution to this problem is to open the JMX-Console and click on the service=Naming to view the MBean view of the Naming service. Check if the port used is still 1099.....
Changed the URL to jnp://182.158.93.41:1299, the client could communicate with the EJB.
If you are running over JBoss AS 5.x
Here is RMI based JNDI description.
RMI-Port: default -1099 / If dynamic port changed to ports-01 Then Port is 1199
Now, Remaining Things are OK, Modify code ass below
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
p.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
p.put(Context.PROVIDER_URL, "jnp://182.158.93.41:1199");
Another Point is case of accessing
SlsSessiongRemote remote=(SlsSessionRemote) context.lookup("SlsSessionBean/remote");
if - #Stateless(name="SlsSessionBean")
Then Remote JNDI- [SlsSessionBean/remote] and Local JNDI - [SlsSessionBean/local]
if - #Stateless(name="SlsSessionBean", mappedName="SlsSessionBeanGlobal")
Then Remote JNDI- [SlsSessionBeanGlobal] and Local JNDI - [SlsSessionBean/local]
I'm trying to use Quartz 1.8.5 (and I also tried Quartz2.0 - same issue) with Spring 3.0.0.
However, I do not want to use Spring's utility wrappers for Quartz schedulers, triggers, jobs...
I would like to create all these objects programmatically from my application, just like in a
standalone Java app with no container - for many reasons, but mainly because i have requirements for
dynamic triggers and JobDetails...
So, I have my quartz.properties on the classpath, where I define a JobStoreTX:
org.quartz.scheduler.instanceName: NotificationsScheduler
org.quartz.scheduler.instanceId: AUTO
org.quartz.scheduler.skipUpdateCheck: true
org.quartz.threadPool.class: org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount: 3
org.quartz.threadPool.threadPriority: 5
org.quartz.jobStore.misfireThreshold: 60000
org.quartz.jobStore.class: org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.driverDelegateClass: org.quartz.impl.jdbcjobstore.StdJDBCDelegate
org.quartz.jobStore.useProperties: false
org.quartz.jobStore.dataSource: qzDS
org.quartz.jobStore.tablePrefix: QRTZ_
org.quartz.jobStore.isClustered: false
org.quartz.dataSource.qzDS.driver: com.mysql.jdbc.Driver
org.quartz.dataSource.qzDS.URL: jdbc:mysql://localhost:3306/myschema
org.quartz.dataSource.qzDS.user: myuser
org.quartz.dataSource.qzDS.password: mypwd
org.quartz.dataSource.qzDS.maxConnections: 5
Then, I have a simple Initializer class, taken almost as is from example1 of Quartz distribution,
which is using an un-modified HelloJob from the same example:
public class NotificationInitializer {
public void init(){
try {
SchedulerFactory schdFact = new StdSchedulerFactory("quartz.properties");
Scheduler schd = schdFact.getScheduler();
schd.start();
JobDetail jd = new JobDetail("hellojob", Scheduler.DEFAULT_GROUP, HelloJob.class);
Trigger t = TriggerUtils.makeImmediateTrigger(2, 1000);
t.setStartTime(new Date());
schd.scheduleJob(jd, t);
// wait long enough so that the scheduler as an opportunity to run
..........
schd.shutdown(true);
} catch (SchedulerException e) {
.....
}
}
}
And I also have a simple unit test that calls this class:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(locations = "classpath:spring/applicationContext.xml")
public class NotificationInitializerTest {
private final static Logger logger = LoggerFactory
.getLogger(NotificationInitializerTest.class);
#BeforeClass
public static void setupClass() {
PropertyConfigurator.configure(Loader
.getResource("spring/log4j.properties"));
PropertyConfigurator.configure(Loader
.getResource("spring/quartz.properties"));
}
#Test
public void testInit() {
NotificationInitializer ni = new NotificationInitializer();
ni.init();
logger.info("NotificationInitializer.init() finished OK");
}
}
And when I run this unit test I'm getting the following errors - see the full stack trace below:
Caused by: org.springframework.beans.factory.BeanCreationException:
Error creating bean with name 'org.springframework.jdbc.datasource.init.DataSour ceInitializer#0':
Invocation of init method failed; nested exception is com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException:
Query was empty
Any idea what went wrong?
Also, I am setting up JobStoreTX for now - just to make sure I can get it working,
but eventually I would like to use the JobStoreCMT toplug intoSpring's transaction management.
I could not find any good documentation/examples on how to do that, especially if I don't want to use
Spring's wrappers for schedulers and hardcode all trigger definitions...
Thanks!

I recently came across this issue too, (I was using Java7 under Mac OS X), the following worked for me:
first of all, test if the method java.net.InetAddress.getLocalHost() works, if it throws exception like:
Caused by: java.net.UnknownHostException: leo-mbp: nodename nor servname provided, or not known
at java.net.Inet6AddressImpl.lookupAllHostAddr(Native Method)
at java.net.InetAddress$1.lookupAllHostAddr(InetAddress.java:901)
at java.net.InetAddress.getAddressesFromNameService(InetAddress.java:1293)
at java.net.InetAddress.getLocalHost(InetAddress.java:1469)
run the following to workaround it:
scutil --set HostName "localhost"
Hope it's helpful to you.
#blob : you were right on target. After spending hours trying to figure out why the NotificationInitializer was not initialized (as the error message suggested....) I finally tried to remove the Quartz DB initialization script from my Spring config - and everything worked like a charm!
<jdbc:initialize-database data-source="dataSource"
enabled="${database.initschema}">
<jdbc:script location="${database.schemaLoc}" />
<jdbc:script location="${database.seedLoc}" />
<!-- <jdbc:script location="classpath:db/tables_mysql_innodb_1.8.5.sql" /> -->
</jdbc:initialize-database>
I just wish Spring error messages were a bit more specific... :)
Now, I still don't understand why I cannot create the DB tables for Quartz this way - the same scripts works just fine when run directly on the DB. Maybe some weird sequence of startup actions in Spring?
thanks!
Only a guess: Check if you need to specify a connection validation query. Something like
validationQuery="select 1"
Changing "org.quartz.scheduler.instanceId" from AUTO to 10 in quartz.properties file worked for me.
I'd like to know how to modify the server.xml file so all my webservices built on axis2 can talk to the DB using Connection Pooling. Each webservice has a different data source, one points to one instance of the DB and the other to another DB server. How do I specify the context that should be used by each service?
Thanks in advance,
Pojo
If you want to use connection pool in your project , Ensure that you have the following code set up for the Tomcat connection pooling to work in context.xml file:
1)Create file with name "context.xml" if it's not exist under directory "WebContent/META-INF/context.xml" with the following content:
For My Project , Please modify it with appropriate value :
<?xml version="1.0" encoding="UTF-8"?>
<Context path="/dbcp" docBase="dbcp">
<Resource name="jdbc/TestDB" auth="Container" type="javax.sql.DataSource"
removeAbandoned="true" removeAbandonedTimeout="30" maxActive="80"
maxIdle="30" maxWait="10000" username="sontn" password="nhantien"
driverClassName="org.postgresql.Driver"
url = "jdbc:postgresql://localhost/group8" useUnicode="true"
characterEncoding="utf-8" characterSetResults="utf8"/>
</Context>
Or you can copy file : context.xml into directory "$Catalian\webapps\axis2\META-INF"
How can you get connection pool?
In your webservice method : create method getConnection() with following content:
public Connection getConnection() {
Connection connection = null;
try {
Context envCtx = (Context) new InitialContext().lookup("java:comp/env");
DataSource ds = (DataSource) envCtx.lookup("jdbc/TestDB");
connection = ds.getConnection();
}
catch (Exception e) {
