I'm creating an EJB in an existent application (running in weblogic 12), to call a method in a Spring component, that calls a DAO annotated as #Transactional to modify a record in the database. The problem is that after call the DAO method I received the following exception:

I'll really appreciate if someone can give a clue on how to solve this error.
Finally the problem was that Spring was using the HibernateTransactionManager instead of WebLogicJtaTransactionManager, because there was another file defining other transaction manager. Once it was changed to have only one file and one transaction manager the exception dissappear.

Note The full stack trace of the root cause is available in the server logs.
Session for transaction; nested exception is
org.hibernate.HibernateException: SessionFactory configured for
multi-tenancy, but no tenant identifier specified
The above error suggests that tenant identifier is not specified. Please double check your configuration and the identifier class implementation name.
The reason you are getting this error is that your tenant identifier resolver needs to return something default in case it cannot find appropriate tenant id from the strategy you have chosen ( in your case you are trying to get the tenant id from request params). I have used the updated code below and it is no longer showing the error.
public class CurrentTenantIdentifierResolverimpl implements CurrentTenantIdentifierResolver {
#Override
public String resolveCurrentTenantIdentifier() {
ServletRequestAttributes attr = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
String tenantId = attr.getRequest().getParameter("tenantId");
if (tenantId==null) {
//return default tenant
return "tenantId1";
}
return tenantId;
}
#Override
public boolean validateExistingCurrentSessions() {
return true;
}
}
Shailendra sir how can we set a tenant id to it without setting default id and get the username from spring security and pass it to the tenant id
I have 2 insert / update statements that i want to wrap in a Spring transaction. If either statement fails i want to have the statements rolled back. I tried to test this with the following scenario:
I have an application which has a DB constraint that it's CODE can only be 25 characters max. I'm forcing a constraint violation while saving a second application by supplying a CODE that is too large.
I would expect that the first insertion / update on application A would have been rolled back. However my test indicates that this is not the case.
I am not quite sure what I am missing ...
My Transation test:
public class SpringTransactionTest {
private static final Logger LOGGER = LoggerFactory.getLogger(SpringTransactionTest.class.getName());
private ApplicationDAO applicationDAO = SpringUtils4Test.getBean(ApplicationDAO.class);
#Transactional
public void doStuff() {
Application a = new Application();
a.setCode("A");
Application b = new Application();
b.setCode("BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB");
a = applicationDAO.insertOrUpdate(a);
LOGGER.debug("a: "+a.getIdentifier());
b = applicationDAO.insertOrUpdate(b);
LOGGER.debug("b: "+b.getIdentifier());
}
#Before
public void cleanIt() {
Application a = applicationDAO.getApplicationByCode("A");
if(a != null && a.getIdentifier() > 0) {
applicationDAO.deleteById(a.getIdentifier());
LOGGER.debug("removed A");
}
Application b = applicationDAO.getApplicationByCode("BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB");
if(b != null && b.getIdentifier() > 0) {
applicationDAO.deleteById(b.getIdentifier());
LOGGER.debug("removed B");
}
}
#Test
public void runTransactionTest() {
try {
doStuff();
} catch (org.springframework.jdbc.UncategorizedSQLException e) {
e.printStackTrace();
}
Assert.assertNull("A should be null, but instead A was found", applicationDAO.getApplicationByCode("A"));
Assert.assertNull("B should be null, but instead B was found", applicationDAO.getApplicationByCode("B"));
}
}

I think #Transactional in junit test is too late
you need to move it to dao (or create business object layer)
when spring creates ctx.getBean, it needs to proxy that class to apply transaction
see if these help
Does Spring #Transactional attribute work on a private method?

I am trying to develop a small spring rmi example.
I have created remote service interface and service as follows,
Calculation.java
package com;
public interface Calculation {
String getName(String name);
}
CalImp:
package com;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class CalImp implements Calculation {
static void init(){
ApplicationContext context = new
ClassPathXmlApplicationContext("applicationContext.xml");
context.getBean("calculationBean");
}
String names;
public String getName(String name){
return names;
}
}
My application context file is
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
<bean id="calculationBean" class="com.CalImp"></bean>
<bean class="org.springframework.remoting.rmi.RmiServiceExporter" destroy-method="destroy">
<property name="serviceName" value="Calculation"></property>
<property name="service" ref="calculationBean"></property>
<property name="serviceInterface" value="com.Calculation"></property>
<property name="replaceExistingBinding" value="true"></property>
<property name="registryPort" value="1199"></property>
</bean>
</beans>
Then my client classes are as follows,
client-beans.xml:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<property name="serviceInterface" value="com.Calculation"></property>
</bean>
</beans>

private Calculation easyServer;
public void setEasyServer(Calculation easyServer) {
this.easyServer = easyServer;
}
public String getdata(){
ApplicationContext context = new ClassPathXmlApplicationContext("client-beans.xml");
easyServer =(Calculation) context.getBean("easyClient");
String name=easyServer.getName("praveen");
return name;
}
}
i tried to test it using the following test utilities,
1) test.java
package com;
import java.rmi.registry.LocateRegistry;
import java.rmi.registry.Registry;
public class Test {
/**
* #param args
*/
public static void main(String[] args) {
Registry registry;
String serverAddress="localhost";
String serverPort="1199";
String text="Hi";
System.out.println("sending "+text+" to "+serverAddress+":"+serverPort);
try{
// get the “registry”
registry=LocateRegistry.getRegistry(serverAddress,(new Integer(serverPort)).intValue());
registry.lookup("Calculation") ;
}
catch(Exception e)
{
e.printStackTrace();
}
}
}
when i tried this i am getting the follwoing exception,even tried with ,my ip "192.#.#.#" , but still no luck.
sending Hi to localhost:1199

Table
CREATE TABLE "STUDENT"
( "SNO" VARCHAR2(20),
"NAME" VARCHAR2(50),
"CITY" VARCHAR2(50),
CONSTRAINT "STUDENT_PK" PRIMARY KEY ("SNO") ENABLE
)
Let me have solution for this. what i have done wrong with this code.
Package of Student class in stacktrace (com.web.entity.Student) does not match to the source code (com.web.emscs.entity.Student). That means that running software was not compiled from the sources presented.
In shown code naming is uniform (com.web.emscs.entity.Student), so executing freshly compiled version will solve problem.
I am learning Spring with Hibernate and am creating a movie rental application using JSF as front end framework.
I have an application scoped managed property in my registration bean which is view scoped. In the register() method to insert the user details in the database, I invoke the service locator implementation bean to get a reference to the required service implementation. However, I get an NPE when I invoke the getter of the service locator property.
Following are my managed beans...
Registration Bean
#ManagedBean
#ViewScoped
public class RegistrationBean extends BaseBean implements Serializable
{
private static final long serialVersionUID = -6449858513581500971L;
private String userID;
private String password;
private String firstName;
private String lastName;
private String email;
private String addressLine1;
private String addressLine2;
private String city;
private String state;
private String pincode;
public RegistrationBean() {
super();
}
// getter / setters...
public String register()
{
String nextPage = null;
try {
RegistrationDetails userDetails = ModelBuilder.populateRegistrationData(this);
// NPE at this line. getServiceLocator() returns null
int registrationID = getServiceLocator().getUserService().registerUser(userDetails);
nextPage = "success";
}
catch (RegistrationException e) {
LOGGER.error(e.getMessage());
}
return nextPage;
}
}
Base Bean
public class BaseBean
{
#ManagedProperty("#{serviceLocator}")
protected IServiceLocator serviceLocator;
protected IServiceLocator getServiceLocator() {
return serviceLocator;
}
public void setServiceLocator(IServiceLocator serviceLocator) {
this.serviceLocator = serviceLocator;
}
}
Service Locator Bean
#ManagedBean
#ApplicationScoped
public class ServiceLocator implements IServiceLocator
{
private static final String USER_SERVICE = "userService";
public ServiceLocator() {

And here is the stacktrace as seen in my Eclipse console

I am using
JSF 2.1 (Mojarra)
Hibernate 4.1
Spring 3.2
Tomcat 7
Eclipse 3.7
Could someone please point out if I have missed something??

This post helped me to make the code work : http://www.javacodegeeks.com/2012/04/jsf-2-primefaces-3-spring-3-hibernate-4.html
However, the code does not work if I keep the Registration Bean as view scoped. Can anyone please help me figure out the reason for the same?
UPDATE: Found the solution for the ViewScope issue : http://blog.harezmi.com.tr/spring-view-scope-for-jsf-2-users/
