I have a simple Java application and I'm trying to integrate Hibernate in Spring but it seems that the Spring configuration file can't find the *.hbm.xml (the mapping resource):
I have a file named persistence-context.xml that I use it as a Spring config file and I have the following bean declared:
org.hibernate.dialect.MySQLDialect
But is being thrown the exception:
java.io.FileNotFoundException: class path resource [pool.hbm.xml] cannot be opened because it does not exist
I've even tried giving the mapping resources property an absolute path value. It doesn't work.
Thank you!
UPDATE:
My Spring conf file:
<?xml version="1.0" encoding="UTF-8"?>

And my pool.hbm.xml is:

</property>
<property name="IdUser">
<column name="ID_User"/>
</property>
<property name="IdSession">
<column name="ID_Session"/>
</property>
</class>
</hibernate-mapping>
And both configuration files are on the same folder.
If you are giving absolute path to the file location on disk (e.g. c:/mapings/pool.hbm.xml), it will not work, because it searches for mapping on a class path. Mapping file should be inside your jar or in IDE class path.
If you are using Tomcat + web project, you should create resource folder inside your src folder and put your mapping files there it will be equal to:
<property name="mappingResources">
<list>
<value>object.hbm.xml</value>
</list>
</property>
Hope it helps.
Use
<property name="mappingResources" value="pool.hbm.xml" />
and put pool.hbm.xml in the root of your classpath. I.e. your bestofs.persistence.PoolBean will be in a directory structure like <somewhere>/bestofs/persistence/PoolBean.class. The mapping file should be inside <somewhere>, right alongside bestofs.
That's all you need to do unless you have some strange ClassLoader magic happening.

anybody has idea why hibernate is not creating tables in my example ?
Here's my web.xml - http://pastebin.com/ZaseSaBS
mvc-dispatcher-servlet.xml - http://pastebin.com/LbdxMSAb
applicationContext.xml - http://pastebin.com/bAHMaVNX
console logs - http://pastebin.com/tTZZbxkX
I have similiar project with almost the same configuration and everything seems to run just fine on the other project. Any ideas why it's not creating tables here?
I've one test enity in com.calculator.enity with #Entity #GeneratedValue annotations, i have it listed in persistence.xml file. There's also JpaRepository for this entity in com.calculator.repository
It looks like your persistence configuration is not properly done. Use this sample persistence configuration as per your requirement. This is working fine for me.

Any ideas as to what's going wrong?
You have a maven project so the User.hbm.xml should be inside src/main/resources/ instead of src/main/java
When you build a maven project then it compiles are the .java files present in src/main/java and it will not consider any other files which are present in this directory. So the maven project has a folder structure src/main/resources where you can place all your configuration files like .xml, .properties etc. So when you build the maven project then it will compile all the java files from src/main/resources and places the .class files in classpath and also maven will copy all the resources from src/main/resources and places them in classpath. So when you run the application then the configuration files will also available in classpath.
But if you just place the configuration files in src/main/java then maven will just ignore them so they will not be available in classpath.
But if the project you are working on is a simple java project instead of maven project then the code setup mentioned in your question will work without any issues even when you have the configuration files in src/main/java. Hope this explanation helps.
To make sure the maven project is build properly you can verify by opening the directory target/classes/ and then the path to your configuration files.
So, to sum up all this information, here's what you need to do:
Creat a package structure in /src/main/resources that mimics the one in /src/main/java - that is, create the net.codejava.spring.model package in /src/main/resources and place User.hbm.xml in there. After running a Maven clean package (or some other build goal) command, the User.hbm.xml file will be in it's correct location (which is not shown in the picture below) - /target/SpringMvcHibernateXML-1.0.0-BUILD-SNAPSHOT/WEB-INF/classes/net/codejava/spring/model/User.hbm.xml.
Ultimately, after building in Maven, the project should look like this:
I created a Spring, Hibernate, Hazelcast integrated application.

The various Hazelcast tutorials ask me to copy the following line of code in Hazelcast.xml.
<management-center enabled="true">http://localhost:8080/mancenter-3.2-RC2</management-center>
But I do not use the Hazelcast.xml which I finally found in the Hazelcast package's bin folder.
Instead I copied Hazelcast jars to my lib folder in eclipse.
What configuration will I need to do in my workspace to run the Mancenter Management Center?
Mancenter Management Center is like a stand alone web application. You can deploy its WAR in your web application server and it should run. To make sure it is up and running, try hitting it from your browser. Once that is done, set you hazelcast to connect to it. This is done in hazelcast.xml.
<management-center enabled="true">http://localhost:8080/mancenter-3.2-RC2</management-center>
Your hazelcast.xml should be in your application classpath - otherwise, the default hazelcast.xml will be used.
Also, make sure that mancenter version and hazelcast version match.
I'm developing a simple standalone Java application using Spring and Hibernate to try to learn them.
I'm having some problems in the configuration of Spring and Hibernate, in order to really create some "useful" result from the code...
I've tried to follow the examples as reported in the book "Beginning Hibernate 2nd edition" and "Pro Spring 3", but i'm having , regarding Hibernate, this problem (i'm using log4j for the logging) :

if i substitute all the placeholders with their values, the program goes on and it connects to the db (if i substitute only one...the error "goes" to the next one)
then it return an incorrect result (an empty list when it should return a list with one element) but maybe i'll ask about it later, if i can't solve it.
Any suggestion?
I don't see any PropertyPlaceholderConfigurer declared in your context. How are property placeholders supposed to be resolved?
One solution is to add
<context:property-placeholder location="classpath:jdbc.properties"/>
to your context.
I am using an XML configuration file that is loaded into my Java application using ApplicationContext.
The XML configuration file resolves its properties by reading from several property files using PropertyPlaceholderConfigurer.
I want to make each property file optional. I thought that this is done by setting ignoreUnresolsvablePlaceholders to true, however I am getting the following exception when I run the application (db-default.properties exists but db.properties does not):
Exception in thread "main" org.springframework.beans.factory.BeanInitializationException: Could not load properties; nested exception is java.io.FileNotFoundException: class path resource [db.properties] cannot be opened because it does not exist
This is what my XML configuration looks like:

What do I need to do to make db.properties an optional property file?
<property name="ignoreResourceNotFound" value="true"/>

This should work too:
<context:property-placeholder ignore-resource-not-found="true" location="classpath:your.properties" ... />
