I'm a beginner in spring and hibernate Frameworks and all I need is a CRUD app complete and working tutorial to start. I tried many tutorials but none of them worked for me :( I'll be so glad if someone could possibly help me..
Have a great day

Publishing JMS message on Solace Topic

I am facing issue while publishing JMS message on Solace server topic.
Actually we are successfully able to send message using jmsTemplate.send() method.
But unable to see the message count on solace client GUI.
Below is my solace configuration.

Based on your comments, it would appear that you are publishing to a topic, but there are no endpoints configured to spool the message.
You can refer to at Adding Topic Subscriptions to Queues for details on how to configure an queue to spool messages that are published to a topic.
To confirm, you can verify whether messages are listed under the "No Subscription Match Logs". In SolAdmin, you can view them by heading to "Logging & Diagnostics" and selecting the "No Subscription Match Logs". The corresponding CLI command for this is show log no-subscription-match
Also, the statistics of your application connection would also display the number of messages received and sent, with any discard reasons. This can be viewed by heading to the "Clients" tab, and selecting the "Client" view. Then, double click on your client and head to "Statistics". Alternatively, the CLI command for this is show client <your-client-name> message-vpn <your-vpn-name> stats

Liquibase Spring error: Could not instantiate bean class [liquibase.integration.spring.SpringLiquibase]

I'm trying to run liquibase changeLog using Spring, as described in docs, but i get the following error:
Could not instantiate bean class [liquibase.integration.spring.SpringLiquibase]:Constructor threw exception; nested exception is java.lang.ExceptionInInitializerError*
This is my applicationContext.xml:
<bean id="dataSourceLb" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
<property name="driverClass" value="com.mysql.jdbc.Driver" />

<property name="dataSource" ref="dataSourceLb" />
<property name="changeLog" value="classpath:mastertest.xml" />
</bean>
and i added this dependency to pom.xml:
<dependency>
<groupId>org.liquibase</groupId>
<artifactId>liquibase-core</artifactId>
<version>3.2.0</version>
</dependency>
mastertest.xml is valid, it runs with maven, but i want to make it run with Spring bean.
What is the problem with this configuration?
I changed changeLog property's value to "classpath:liquibase/mastertest.xml" because mastertest.xml is in the ProjectHome/src/main/resources/liquibase folder, and it is working now.

Eclipse Virgo Injected JPA EntityManager does not connect to Database

I am using Eclipse Virgo and I am trying to get annotation driven transaction management running but I keep running into the same issue.
Problem is that the EntityManager is injected and not null. But any query fails due to a connection error.
I used the setup according to GreenPages.
I have the following EntityManageFactory and TransactionManager configured
<bean id="emf"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceXmlLocation" value="classpath:META-INF/persistence.xml" />
<property name="dataSource" ref="dataSource" />
<property name="persistenceUnitName" value="ShiftManagement" />
<property name="jpaVendorAdapter">
<bean
class="org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapter">
<property name="showSql" value="true" />
<property name="generateDdl" value="true" />
<property name="databasePlatform"

</bean>
</property>
<property name="packagesToScan" value="....." />
<property name="jpaDialect">
<bean class="org.springframework.orm.jpa.vendor.EclipseLinkJpaDialect" />
</property>
</bean>
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="emf" />
</bean>
<tx:annotation-driven transaction-manager="transactionManager" />
Also I have the following DataSources configured. Problem is, I tried them all, but when I try to connect to the database using a query, it doesn't work. Now, I am 100% sure that the credentials are OK, the DB is UP etc etc
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/shiftmanagement" />

<property name="initialSize" value="5" />
<property name="maxActive" value="20" />
<property name="maxIdle" value="5" />

Error when using commons-dbcp

OK so then I tried the promising tomcat-jdbc library
<bean id="dataSource3" class="org.apache.tomcat.jdbc.pool.DataSource"
destroy-method="close">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/shiftmanagement" />

<property name="initialSize" value="5" />
<property name="maxActive" value="10" />
<property name="maxIdle" value="5" />
<property name="minIdle" value="2" />
</bean>
And the following similar exception pops up
Caused by: org.eclipse.virgo.kernel.osgi.framework.ExtendedClassNotFoundException: com.mysql.jdbc.Driver in KernelBundleClassLoader: [bundle=org.apache.tomcat.jdbc_1.1.0.1]

</persistence-unit>
I inject the EntityManager using
#PersistenceContext
private EntityManager em;
I read some posts to remove the username and password from the persistence.xml but then the system complains there are that user = [null].
Any help is greatly appreciated.
Note: mysqld is running and I can connect using mysql -uroot -prootroot
OK so I used a fourth datasource and all my problems dissapeared :-)
<bean id="dataSource"
class="org.springframework.jdbc.datasource.SimpleDriverDataSource">
<property name="driverClass" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/shiftmanagement" />
<property name="username" value="${javax.persistence.jdbc.user}" />
<property name="password" value="${javax.persistence.jdbc.password}" />
</bean>
You have to use the org.springframework.jdbc.datasource.DriverManagerDataSource see this thread
And in this case you see that the mysql driver is not found
Caused by: java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/shiftmanagement

Spring PropertyPlaceholderConfigurer failed for 2 dataSources

For single one it works perfectly, but when I delete comments from the second one "rbmDataSource", it fails.
I can't understand why?

HTML page and Spring

I create Simple MVC project in Spring. Defaultr generic a jsp pages. I try change jsp to html and i:
<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<beans:property name="prefix" value="/WEB-INF/views/" />
<beans:property name="suffix" value=".jsp" />
</beans:bean>
replace this:
<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<beans:property name="prefix" value="/WEB-INF/views/" />
<beans:property name="suffix" value=".html" />
</beans:bean>
and create html page in views folder, but after changes and try run i have this error:
WARN : org.springframework.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/myapp/WEB-INF/views/home.html] in DispatcherServlet with name 'appServlet'
Why i have this error? I only change jsp to html.
The InternalResourceViewResolverdoes not forward the request to the view folder. Instead it is responsible for selecting the 'jsp' (or what ever) according to the return value of an Controller(Method). Like
#RequestMapping("home")
public ModelAndView controllerMethodForHome(){
//will render /WEB-INF/views/homeView.html
return new ModelAndView("homeView");
}
with:
<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<beans:property name="prefix" value="/WEB-INF/views/" />
<beans:property name="suffix" value=".html" />
</beans:bean>
will return the /WEB-INF/views/homeView.html for localhost:8080/myApp/home
Maybe the thing you want to use is the static resource mapping
<mvc:resources mapping="/css/**" location="/resources/css/" />
Have a look at this question/answer for an example
