I tried one solution (adding #Transactional annotation in service layer on method connecting to hibernate,but now i'm getting 2 exceptions:
Could not open Hibernate Session for transaction; nested exception is org.hibernate.exception.GenericJDBCException: Could not open connection, any solutions?
-maybe the problem is related with this: Cannot load JDBC driver class 'com.postgresql.jdbc.Driver'
-no one was able to help me, I have all neccesary dependencies, but don't know what's wrong, thanks
You cannot connect because the driver is not on the classpath.
You can download from here: http://jdbc.postgresql.org/download.html.
It could solve your jdbc class loading problems.
Make sure you have wired in the SessionFactory bean into your dao implementation class.
One way of doing that is as follow:
#Resource
private SessionFactory mySessionFactory;
Let's start the following segment:
<property name="driverClassName" value="com.postgresql.jdbc.Driver"/>
I used "com.postgresql.jdbc.Driver" as well for driverClassName and got the same error as you are getting. The only difference is I gave the database connection details in a resource.xml file and used resource injection to initiate the database connectivity from Java files.
<Context>
<Resource name="jdbc/test"
auth="Container" type="javax.sql.DataSource"
maxActive="20" maxIdle="5" maxWait="10000"
username="postgres" password="password"
driverClassName="org.postgresql.Driver"
url="jdbc:postgresql://localhost:5432/test?allowPublicKeyRetrieval=true"/>
</Context>
My issue got resolved and there are no issues with database connectivity after I have used driverClassName="org.postgresql.Driver" instead of driverClassName="com.postgresql.jdbc.Driver".
Try the below code instead:
<property name="driverClassName" value="org.postgresql.Driver"/>
Clean the project once or multiple times before running with the new code. Once the changes get implemented, it starts working properly.

I am new to spring. And I have encounter an error on my spring application. It says :

I have beean dealing with this for a long time now... It has been 5 days. And this is what I have done...

Stop,clean or/and delete server
Rewrite entire code
Download the org.springframework.web.servlet.DispatcherServlet and try to run again.
I would appreciate the help to all if possible.

Thank you all for the help it made my think again. So I refactor the code from zero checked the libraries and it ran smoothly. So the issue was with the libraries because after refactoring the code it did not work. But checking the libraries it worked.
Hello guys i have been playing around with spring mvc and hibernate. But now i am getting an error when trying to connect both hibernate and spring with XML configuration. I get this error below:

I created my webapp folder in src/main. in my webapp folder i created WEB-INF folder. And WEB-INF folder contained files: service.xml, dispatcher-servlet.xml. Now for my hibernate.cfg.xml, it was placed in src/main folder structure. But when i try to add it in the service.xml upon loading the dispatcher, my hibernate.cfg.xml seems not to be found. Does anyone know why? This is where i am having trouble:
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">

<property name="configLocation" value="" />

I can't seem to find the value of configLocation. Has anyone encountered this issue.

I fixed my error by placing hibernate.cfg.xmlin the root directory of WEB-INF. That is placed in webapp folder and solved my issue.
you have already defined "DataSource" bean, I guess you don't need to configLocation property.
you can refer below link for more options http://www.mkyong.com/spring/maven-spring-hibernate-mysql-example

And mine controller:
public class MainController {

public String HelloWorld(Model model,Device device){
logger.info("Device is "+device);
if(device.isNormal()){
return "hello";
}
return "index";
}
}
Mine webapp folder look like this:
WEB-INF---
|
pages---
|
mobile---
|
index.html
So, the redirecting work just fine,I'm getting redirected to mobile version. But page i'm redirected to is non existing(404). I' just can't see the error. Thank you in advance.
"rotate" the redirect to url to sitename:8080/studentacc/m" because it is likely that "studentacc" is the name of your application in the application server, and therefore it must be the first part.
From a very short look to the API, I would try to use the SiteSwitcherHandlerInterceptor.urlPath(String mobilePath, String rootPath) method with the additional parameter for the rootPath
<bean class="org.springframework.mobile.device.switcher.SiteSwitcherHandlerInterceptor" factory-method="urlPath">
<constructor-arg value="/m" />
<constructor-arg value="/studentacc" />
</bean>
I'm trying to implement solr search with Spring and postgres using maven but on running the appilcation i get 404 with the exception

I think there is something wrong with the configuration or something as i am new to solr.
Thanks for the help.
Generally this kind of error is due to a recursive infinite loop. Do you have some own code executed at server startup ?
The basics behind this error was the use the use of both Solrj and Spring-data-solr it is basically because of the logger used in these API's call each other recursively until the stack overflow error is thrown bring down the tomcat. So i removed the spring-data-solr dependency from my pom.
The purpose of slf4j-jcl module is to delegate or redirect calls made to an SLF4J logger to jakarta commons logging (JCL).
The purpose of the jcl-over-slf4j module is to redirect calls made to a JCL logger to SLF4J.
If both slf4j-jcl.jar and jcl-over-slf4j.jar are present on the class path, then a StackOverflowError will inevitably occur immediately after the first invocation of an SLF4J or a JCL logger.
The problem is described in the link http://www.slf4j.org/legacy.html
Trying to find if there is a workaround for the same.
What do you mean when you say you run your application ? Are you running some sort of searching or you mean when the welcome page is loading ?
Is there a specific page you access by default when you run your application ?
Did you try and put some debug points in the piece of code which runs when you start up your application ?
Or do you mean you get this error when you start your server after deploying your application ?
I have an existing Spring application that does some server side processing. I am trying to create a webapp for this particular application and chose SpringMVC to serve my purpose.
I created a display controller as follows:
#Controller
#RequestMapping("/items")
public class ItemDisplayController {
private static final Logger LOGGER = Logger.getLogger(ItemDisplayController.class);
private static final String ITEMS_REDIRECT = "redirect:/item/items";

I already have an applicationContext file with the following definitions:

In my *servlet.xml, I have defined the ViewResolver as follows:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

And in the web.xml, I have the context-param defined:
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</servlet-mapping>
</web-app>
When I run my application, the itemDisplay is not wired up and on the debugger it is showing up with a null value.
Can somebody point out what I may be doing wrong here? In an ideal world, I would assume that annotating the itemDisplay with #Autowired in the controller would help resolve the implementation of the interface.
Only thing I can think of is, ContextLoaderListener does not complain if the applicationContext.xml is not found, Let's try this add classpath*:applicationContext.xml also make sure applicationContext.xml is run time class path of the server
Here is an excellent article that provides a good insight into spring classpath resource.
Your files looks up fine at quick glance. As long as there is only one bean with of ItemDisplay type in your context it should be autowired by type, otherwise you should get error in log file.
One small thing I noticed, which is probably unrelated to your particular issue, is that you map your 'items' controller to all files in web.xml. Usually you would want it to map to particular type of files only - say *.htm so it won't get called for resources such as images etc.
Not sure if this is a typo in your applicationContext file :
<bean id="itemDisplay" class="com.acme.itemDisplayImpl"/>
Shouldn't the class be com.acme.item.DisplayImpl ?. If the name of class is indeed itemDisplayImpl, then you need to change the component-scan element in *servlet.xml to include the correct package.
