I am having a simple trigger bean which should be fired for every 20min.
For that I am specifying the repeatinterval value in properties file. But my job is getting waked up every minute instead of every 20min.
sample xml
<bean id="propertyLoaderJob"
class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="propertyloader" />
<property name="targetMethod" value="propFlagValidator" />
<property name="concurrent" value="false" />
</bean>
<bean id="propertyLoaderTrigger"
class="org.springframework.scheduling.quartz.SimpleTriggerBean">
<property name="jobDetail" ref="propertyLoaderJob" />
<property name="repeatInterval" value="${quartz.scheduler.repeatInterval}" />
<property name="startDelay" value="${quartz.scheduler.startDelay}" />
</bean>
in the properties file I have these fields
quartz.scheduler.repeatInterval=1200000
quartz.scheduler.startDelay=1000
What could be the possbile reason for this?
Please help.
Thanks in advance.
Have you specified a property placeholder for this,
Using Context namespace,
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">
. . .
<context:property-placeholder location="quartz.scheduler.properties" />
. . .
</beans>
or Adding PropertyPlaceholderConfigurer bean in application context
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location">
<value>classpath:quartz.scheduler.properties</value>
</property>
</bean>
Are you sure that you are not using any other trigger for the same class/job i.e. propertyLoaderJob. It may have happened that you are using a cron expression as well associated with the same job. It will be great if you can share the complete spring xml file.
For future reference i am answering.
Along with the mentioned part in my question i forgot to add the below code. That is for actually triggering it:
<bean name="nonclusterMode" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<ref bean="propertyLoaderTrigger" />
</list>
</property>
</bean>
Now it is working as expected.

We have a spring-based application that is failing to deploy on a Weblogic 10.3 container. Upon deployment, the application attempts to look up two local JMS queues within the Weblogic container's JMS module and, when the deployment takes place, the application locates one local queue okay but not the other.
Both queues are configured exactly the same except for their names are different. Why does the application locate one queue okay but not the other???
I've checked queue names JNDI names many times over and I can't see any spelling errors or anything like that.
I have turned trace logging on and I can see that the connection factory used to look up both queues is the same, the spring JMS configuration is exactly the same for both queues yet one it finds the other it does not.
I don't know what else to check to establish what the problem might be... any ideas?
This is the error I get when it fails to look up one of the queues in the Weblogic JNDI tree:
Caused by: javax.naming.NameNotFoundException: Unable to resolve 'QUEUE_NAME'. Resolved ''; remaining name 'QUEUE_NAME'
at weblogic.jndi.internal.BasicNamingNode.newNameNotFoundException(BasicNamingNode.java:1139)
PS: Both queues have the same Subdeployment and same Targets configured.

Can you have a look to the JDNI tree in your running server to check if the queue is created or not, and to which jndi name it is bound to ? Use the admin console for this purpose.

Maybe there's something wrong with mappingResources property class is incorrect or something. However, what I have specified there is full classpath for that hibernate xml config. So what could be the problem? Please help me.
Source of a java.lang.NoClassDefFoundError is most of time a problem in classpath. Here you have to check that Spring TX and Hibernate are present in the classpath.
Please add spring tx jar in your class path.I faced the same issue and solved by adding the spring-tx jar.
I have read many tutorials to config spring with JPA. I am using a local MySQL database and i have this context:

I have a test on JUnit to test my DAO and works nice but when i try to persist an entity with this config, i never the in hibernate log the insert command but in test case i see it. If i try to make a entitymanager.flush i get an exception because any transaction is running.
What i should change to can make persist on my local database with this entities?
thanks
If i try to make a entitymanager.flush i get an exception because any transaction is running.
If I'm reading that right, the problem is you're trying to save something without starting a transaction. Transactions are required when changing persistent state.
In order to be able to persist in database it is mandatory to be within a transaction. So the better you can solve it is to annotate #Transactional ... e.g. on the method
This also make me crazy for couple of hours some time ago.
are you using annotations in your classes? if so please make sure you
<context:component-scan base-package="com.vitornobrega.myapp"> because arpart from the jpa configurations i can see where you are injecting your dependencies.
I am using Hibernate in combination with Spring. As database I am currently using HSQL, which stores its data in a file (like SQLite). The path to the HSQL file is currently hard-coded in the persistence.xml. How can I access and change this value at runtime, so a user can load and save from/to an arbitrary HSQL file?

Thanks for any hint!
You can specify a JNDI datasource and pass it to Hibernate. Or you can define your own plugin strategy for obtaining JDBC connections by implementing the interface org.hibernate.connection.ConnectionProvider
For more hints see: http://docs.jboss.org/hibernate/orm/3.3/reference/en/html/session-configuration.html
Edit 2/16: There is an example on StackOverflow on creating a custom ConnectionProvider: How can I set Datasource when I'm creating Hibernate SessionFactory?
If you are going to change the data source on the fly, rather than at the startup, you will have to restart the Hibernate session factory. To do it correctly, you will have to make sure that no transactions are running in it at the time of the restart. Following question/answers would help you with that: Hibernate Sessionfactory restart | Spring
A commonly used strategy is to define all runtime configurations in one or several *.properties files and use spring's PropertyPlaceholderConfigurer to load the values and substitute the placeholder in applicationContext.xml, read more here: Best ways to deal with properties values in XML file in Spring, Maven and Eclipses.
app.properties:
# Dadabase connection settings:
hibernate.connection.driver_class=org.hsqldb.jdbcDriver
hibernate.connection.url=jdbc:hsqldb:file:~/something-db/somethingdb
hibernate.connection.username=sa
hibernate.connection.password=changeit
hibernate.dialect=org.hibernate.dialect.HSQLDialect
hbm2ddl.auto=update
... ...
applicationContext-dataStore.xml:
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<!-- Default location inside war file -->
<value>classpath:app.properties</value>
<!-- Environment specific location, a fixed path on deployment server -->
<value>file:///opt/my-app/conf/app.properties</value>
</list>
</property>
<property name="ignoreResourceNotFound" value="true"/>
</bean>
... ...
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${hibernate.connection.driver_class}" />
<property name="url" value="${hibernate.connection.url}" />
<property name="username" value="${hibernate.connection.username}" />
<property name="password" value="${hibernate.connection.password}" />
</bean>
One problem here is the PropertyPlaceholderConfigurer doesn't parse persistence.xml, the solution is to move all hibernate configuration into Spring's applicationContext.xml, as it is not necessary to set them in persistence.xml. read more here: loading .properties in spring-context.xml and persistence.xml.

Note that the web application need to be restarted every time you alter the configuration in /opt/my-app/conf/app.properties, in order to make changes take effect.
Hope this helps.
If you wish to use hibernate via the JPA Abstraction you can we-write your code or service to use an javax.persistence.EntityManagerFactory. Autowire one of these and call createEntityManager(Map map); You can provide a datasource in the map. You could wrap the entity manager with your own implementation that pulls the parameter off a thread-local for creating the datasource.
EDIT: Mis-read the context and saw you are using an EntityManagerFactory. In which case just read the last part where you wrap the Factory with a delegate that creates the correct datasource from a threadlocal.
Fairly new to Spring, so I'm having some trouble with this. I'm trying to use LDAP security with Spring. I can use a properties file I created inside the webapp itself. But what I would like to do is load and read the context.xml file of the server (it has all the values I need for this and other applications).
This is what I have:
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="ignoreUnresolvablePlaceholders" value="true"/>
</bean>
<bean class="org.springframework.web.context.support.ServletContextPropertyPlaceholderConfigurer">
<property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/>
<property name="searchContextAttributes" value="true"/>
<property name="contextOverride" value="true"/>
<property name="ignoreResourceNotFound" value="true"/>
<property name="locations">
<list>
<value>/WEB-INF/properties/dataUploadProperties.properties</value>
<value>/WEB-INF/properties/globalProperties.properties</value>
<value>context.xml</value>
</list>
</property>
</bean>
I'm able to load and read the 2 properties files, but the context.xml is not found. Does it need to be the absolute path on the server?
Thanks
Chris
So the first thing I would recommend is to use Spring Security. It has an already build in LDAP support.
but the context.xml is not found
Normally this (reading the context.xml directly) is not the way you should go.
Instead, define some properties and or JNDI resources in the context.xml and then use them in the spring configuration.
