here is the code.
FileSystemResource newResource = new FileSystemResource("spring.xml");
BeanFactory factory = new XmlBeanFactory(newResource);
Triangle triangle = (Triangle) factory.getBean("triangle");
triangle.draw();
Can anyone please tell me why I get this exception and How do I resolve it?
error is thrown at first line (FileSystemResource newResource = new FileSyste....)
Thanks in advance :)
You should use ApplicationContext instead:
ApplicationContext ctx = new FileSystemXmlApplicationContext("spring.xml");
But, of course, you have to provide correct config file location: seems to me full path.

I have the following bean definition.
#Bean
public DataSource hikariDataSource() {
HikariConfig hikariConfig = new HikariConfig();
hikariConfig.setJdbcUrl(JDBC_URL);
hikariConfig.setUsername(USERNAME);
hikariConfig.setPassword(PASSWORD);
return new HikariDataSource(hikariConfig);
}
When I get application context.
ApplicationContext ctx = new AnnotationConfigApplicationContext("org.example");
An exception is being thrown
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'hikariDataSource' defined in org.example.config.Configuration: Failed to instantiate [javax.sql.DataSource]: Factory method 'hikariDataSource' threw exception with message: null
Is there any idea what can be the reason?
Maybe some of the answers from this thread will help.
https://stackoverflow.com/a/33213802/3816621
Also please check if you get #Configuration annotation on class level.
Exception in thread "main" java.lang.ClassCastException :

How can I do to resolve this exception? Even after casting I am getting the same exception.
You can try the following
XmlBeanFactory beanFactory = new XmlBeanFactory(new ClassPathResource("applicationContext.xml"));
But, it is recommended to use ApplicationContext as it provides more benefits than just a beanfactory.
context = new ClassPathXmlApplicationContext("applicationContext.xml");
Student student=(Student)factory.getBean("studentbean");
I get this error when I try to access to the servlet named BookingServlet
Grave: exception caught
javax.naming.NamingException: Lookup failed for 'java:global/it.volaconnoi_VolaConNoi_webapp-ear_ear_1.0-SNAPSHOT/it.volaconnoi_VolaConNoi_webapp-ejb_ejb_1.0-SNAPSHOT/BookingBean!it.volaconnoi.logic.BookingBeanInterface' in SerialContext[myEnv={java.naming.factory.initial=com.sun.enterprise.naming.impl.SerialInitContextFactory, java.naming.factory.state=com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl, java.naming.factory.url.pkgs=com.sun.enterprise.naming} [Root exception is javax.naming.NameNotFoundException: it.volaconnoi_VolaConNoi_webapp-ear_ear_1.0-SNAPSHOT]
and this is the screenshot
The project is deployed correctly but I don't understand why I get this error. Do you any suggest?
As you may see the booking servlet is in its place
EDIT
BookingBeanInterface bookingBean = lookupBookingBeanLocal();
private BookingBeanInterface lookupBookingBeanLocal() {
try {
Context c = new InitialContext();
return (BookingBeanInterface) c.lookup("java:global/it.volaconnoi_volaconnoi-webapp-ear_ear_1.0-SNAPSHOT/it.volaconnoi_volaconnoi-webapp-ejb_ejb_1.0-SNAPSHOT/BookingBean!it.volaconnoi.logic.BookingBeanInterface");
} catch (NamingException ne) {
Logger.getLogger(getClass().getName()).log(Level.SEVERE, "exception caught", ne);
throw new RuntimeException(ne);
}
}
Really not enough description, you should describe where is your class BookingBean is located, and by what means it registered in JNDI. But if we assume that registration is correct, you could try to lookup it using following string:
c.lookup("java:app/BookingBean/it.volaconnoi.logic.BookingBeanInterface");

I am working on an SUP MBO project. I am trying to use a Result Set Filter to customize my MBO. In that class, I need http get something and customize the MBO rows based on the feedback. I use MobileSDK of SUP2.1.2 and try preview the resultset. I enabled the debugging and can see the output from the console.
The changed result set filter code piece looks like:
#Override
public ResultSet filter(ResultSet in, Map arg1)
throws Exception {
DefaultHttpClient httpclient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet("www.google.com");
HttpResponse response1 = httpclient.execute(httpGet);
httpGet.releaseConnection();
return in;
}
Each time when httpclient.execute(httpGet) gets called, an exception is thrown out as below:

I tried different httpclient jar versions (including 3.0.1, 4.2) but always got the same failure.
Does anyone have any hint? Thanks.
Got the solution from here
Hi,
Normally "java.lang.reflect.InvocationTargetException" occurs when java compiler finds 2 different classes with same name in 2 different packages. when u r importing both classes at a time and when you r trying to create object of that class it throws "java.lang.reflect.InvocationTargetException" exception .
The solution is that when you are creating the object of the class use package name also along with class name so that compiler knows what class it has to use.
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.
