My #Transactionnal annotations seems to be ignored. I have no errors on the initialization of the Spring container. It looks like my method has not been proxied by Spring TX framework. During the execution of my service's method, an expected RuntimeException is thrown by the JDBCTemplate. The problem is that the JDBC connection is not rolledbacked and changes are persisted. The stacktrace doesn't show any sign of the proxy who is supposed to wrap my service's method.
Edit : Added the Controller's code
Edit 2 : Added the Service's Interface
Here is my Service Interface.
public interface ApplicationsService {
public Application getApplicationById(int id);
public void createApplication(Application application);
public void createInstance(Application application);
public Map<Integer, Application> getUserApplications(String username);
public Application newApplication(String email);
}
Here is my Service.
#Service
public class ApplicationsServiceImpl implements ApplicationsService {
...
#Transactional
public void createApplication(Application application){
// Persisting the application.
applicationDAO.createApplication(application);
application.setId(
applicationDAO.findApplicationId(application.getName(), application.getAccount().getEmail())
);
// Creating the physical instance.
createInstance(application);
}
...
}
Spring Controller responsible for the method call.
#Controller
#RequestMapping("/applications")
public class ApplicationsController {
...
#Autowired
private ApplicationsService applicationsService;
...
#RequestMapping(method=RequestMethod.POST)
public String saveApplication(
#Valid Application application,
BindingResult bindingResult,
Principal principal
){
application.setAccount(this.accountService.getAccount(principal.getName()));
this.applicationsService.createApplication(application);
return "application/creatingApplication";
}
...
}
Here is my Spring transaction configuration

During the execution of the createApplication, a RuntimeException is launched by the JDBCTemplate and the transaction is not rollbacked.

My guess is that you've put your service beans in the context that belongs to the dispatcher servlet, where only controller beans are supposed to live, and then you've declared your transaction beans in the root context. The annotation-based transaction auto-proxying only applies within a single context, so your service beans in the other (wrong) context won't be affected. See my answer to "Why DispatcherServlet creates another application context?" for a fuller description of the problem. The root problem is that you don't understand how contexts are organized in a Spring MVC application.
You need to define an interface for the #Transactional annotations to work:
public interface ApplicationsService {
public void createApplication(Application application);
}
And the concrete class:
#Service
public class ApplicationsServiceImpl {
#Transactional
public void createApplication(Application application) {
// ...
}
}
Alternatively, per Kevin Welker's comment, if don't want an interface (though you probably should write an interface), you can configure use proxy-target-class:
<tx:annotation-driven proxy-target-class="true" />
edit
The message from your SQLException is:
Field 'status' doesn't have a default value
So maybe you're passing in null where you should be providing a value? Alternatively, check this post for some weirdness associated with this error.
After three days of debugging, I finally found the reason why my annotations were ignored.
The <tx:annotation-driven/> instruction located in a child context file doesn't have access to the beans created by its parent Spring context.
I had to move it to the myapp-servlet.xml used by my request dispatcher.
Now, it is working properly.

Once I click my login button the error occurs. Similar questions on stackoverflow seem to indicate a dependency problem but all dependencies seem to be in place.
I got the same error when I included org.springframework.core-3.1.0.M2.jar in my project. I looked inside the jar and opened org.springframework.jdbc.core.StatementCreatorUtils class.I found that it is using a class SpringProperties which is not part of above jar.
I replaced above JAR with spring-core-4.2.0.RELEASE.jar and it started working.
I didn't do anythin apart from adding this jar file to my lib directory for my project spring-core-4.0.6.RELEASE.jar, alternatively we can add this to our build path. I hope this helps.
I am working with a project with accesses a JNDI datasource in tomcat 7. Here is my META-INF/context.xml files:
<?xml version="1.0" encoding="UTF-8"?>
<Context>

username="root" password=""
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/ANTTestDb"/>
</Context>
This is my dao class, the dataSource is successfully injected to my class via context lookup service as you see below:
public class CoffeeDataBase {
private DataSource dataSource;
public CoffeeDataBase() {
try {
Context ctx = new InitialContext();
dataSource = (DataSource) ctx.lookup("java:comp/env/jdbc/ambes");
} catch (Exception e) {
e.printStackTrace();
}
// other methods definition
}
but when i replace the lookup service with #Resourse anotaion like this:
#Resource(lookup="java:comp/env/jdbc/ambes")
public class CoffeeDataBase {
private DataSource dataSource;
public CoffeeDataBase() {
}
// other methods definition
}
i am getting this NullPointerExeption like this:

I have also tried #Resource(name="jdbc/ambes") but same exception!
Tomcat does not support #Resource injection. So you can only use context lookup service in you are working in Tomcat. You can also use dependency injection framework spring to inject the dataSource which enables you to use #Resource anotation.
I want to update a properties file from my Controller. I am having n different project modules in my web app. The properties file is there in module A resources and I want to access it from module B UI Controller. I have the added the dependency of module A, the module A is there as a jar file in module B/libs/A.jar. I can open the property file as InputStream but I cannot open it as FileOutputStream. I don't know how to access that property file as Output stream.
The approaches that I have already tried are loading a property file directly as well as by using the class loader.
Please let me know if I am doing anything wrong
Code :
public static void storeProperties() {
Properties properties = getInstance();
try {
String path = L2L3Resource.class.getClassLoader().getResource("policy.properties").getPath();
FileOutputStream fout = new FileOutputStream(new File(path).getAbsolutePath()); \\ this is line number 54
properties.store(fout, null);
}
catch (FileNotFoundException e) {
e.printStackTrace();
}
catch (IOException e) {
e.printStackTrace();
}
}
Following is the stack trace I am getting when tried to use class path loader - NullPointerException
java.io.FileNotFoundException: D:\J2EE\apache-tomcat-7.0.35\webapps\xyz-webui-1.0.0\WEB-INF\lib\xyz-module-1.0.0.jar\policy.properties (The system cannot find the path specified)

So, with your last comment there's the answer, you cannot open a file inside a jar package for writing. I wouldn't even expect it to open for reading either, but well, I learned something new...
What you need to do is put the file outside the jar file. Sometimes people use a resources directory in maven for that. Or you can have a external config directory, it will certainly be a design decision, but the file must be directly on the file system, outside of any jar file.
MAybe this can help:

I have a web application that uses the Spring Framework (3.1) and persistence through JPA (2.0) backened by Hibernate (4.1.1)
Hibernate Search is also enabled (4.1 RC). Hibernate's Second Level cache is Infinispan (5.1.3).
I also use Infinispan as Lucene (3.5) Directory Provider (for Hibernate Search).
Everything runs over XA transactions, with Bitronix (2.1.2) as JTA manager.
I have methods annotated with #Transactional. When the method ends, and the transaction commits, the following exception occurs:

You'll notice the Hibernate class "SynchronizationRegistryImpl". This one holds a set of javax.transaction.Synchronization objects. What I think is happening is that Hibernate itself is registered as a Synchronization in this set. So,
After commit, two events fire: beforeTransactionCompletion and afterTransactionCompletion.
beforeTransactionCompletion goes well.
afterTransactionCompletation starts and the method notifySynchronizationsAfterTransactionCompletion is called.
This method calls afterCompletion on each of the Synchronization elements of the Set.
One of the item in the set (not the last) is an Hibernate item, which calls some clean up.
This clean up empties the Set.
ConcurrentModificationException is thrown because the set was cleaned while it was being iterated.
Maybe I have configured Hibernate incorrectly. My Spring XML are too big to be put here. Luckily some of you guys have an idea of why this is happening.
More data (which may or may not be useful) to establish context:
Other of the items in the Synchronization set belongs to Hibernate Search.
The database datasource is PostgreSQL.
I'm using XA because there is also an ActiveMQ JMS in the transaction, and at first Infinispan was set as a XA resource too (now it hooks to the JTA Synchronization).
Spring Security is enabled.
Hibernate connects to JTA by CMTTransactionFactory.
I'm not sure if the PersistenceContext is "transactional" or "extended", but from debugging it looks like the latter.
It turned out that there was more Infinispan configuration needed, that I didn't know it existed.
In the transaction tag (under default configuration), even though I set up the transanction manager lookup, I had to explicity add the attribute transactionMode="TRANSACTIONAL".
I was also using the default configuration for the caches that Hibernate uses, their names are: entity, local-query, and timestamp. There is a file named infinispan-configs.xml located in the hibernate-infinispan.jar that helps to setup the desired configuration.
UPDATE: disregard this answer. The issue appeared again, and it's this bug.
I have a Spring MVC webapp that should serve static resources.
Therefore I have the following spring configuration:
<mvc:resources location="/resources/" mapping="/resources/**"/>
But each request to a resource leads to the same ugly ClassCastException:

I tried it with version 3.1.0.RELEASE and 3.0.4.RELEASE of the spring framework and observed the exact same behavior.
You may be missing mvc:annotation-driven in your configuration, that is the one which registers the property editor to transform from string to a resource, that is likely causing this error message for you.
This is really weird, but the problem seems to be, that I had defined a conversion service like this:
<bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
<property name="converters">
<list>
<bean class="com.example.CustomConverter" />
</list>
</property>
</bean>
Which was referenced here:
<mvc:annotation-driven conversion-service="conversionService" />
Turns out if I change the bean id to something different like f. e. cs it works fine. This is really strange as the same id is used in the documentation and the showcases.
