I am not able to get the db operations working using hibernate in apache servicemix. I am using oracle database and reading from the database table in the camel-context route using hibernate.
Actually when I run the camel-context locally from Fuse IDE, the db operations work, but when I bundle the project and deploy it in servicemix I am unable to resolve the dependencies related to hibernate. Installing the project bundle into servicemix gives following dependency errors related to hibernate: 1. Class not found - org/hibernate/ejb/HibernatePersistence To fix this I installed hibernate-entitymanager-3.6.2.Final.jar, I bundled the jar using bnd tool and then installed it in servicemix. I also put in this package under <Importe-Package> in bundle plugin in my project pom.xml. This resolved the dependency error . 2. Next error is Class not found - org/hibernate/MappingException For this I can install either hibernate-core-3.6.2.Final or hibernate-3.6.2.Final ( aggregate jar). But when I install any of these jars the hibernate-entitymanager installed in (1) above fails saying that it exports org.hibernate.engine which is also exported by hibernate-core. How can I solve this error ? Actually most of the hibernate jars have duplicate packages in them. For e.g. hibernate-core, hibernate and hibernate-entitymanager having org.hibernate.engine. Also org.hibernate.annotations package is present in multiple jars. How can these jars co-exists in servicemix if I need to install all of them? How can I get this dependency resolved ? Following is my camel-context and spring bean configuration for reference (EmployeeEntity mentioned below is the DB mapping class): /<beans xmlns="http://www.springframework.org/schema/beans"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xmlns:camel="http://camel.apache.org/schema/spring"; xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd";> <camelContext xmlns="http://camel.apache.org/schema/spring";> <route> <description>DB Test App</description> <from uri="jpa:test.demo.EmployeeEntity"/> <to uri="mock:result"/> </route> </camelContext> <bean id="jpa" class="org.apache.camel.component.jpa.JpaComponent"> <property name="entityManagerFactory" ref="entityManagerFactory" /> </bean> <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="persistenceUnitName" value="camel" /> <property name="jpaVendorAdapter" ref="jpaAdapter" /> </bean> <bean id="jpaAdapter" class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"> <property name="databasePlatform" value="org.hibernate.dialect.OracleDialect" /> </bean> </beans>/ Following is my persistence.xml: /<persistence xmlns="http://java.sun.com/xml/ns/persistence"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; version="1.0"> <persistence-unit name="camel" transaction-type="RESOURCE_LOCAL"> <class>test.demo.EmployeeEntity</class> <properties> <property name="hibernate.connection.url" value="jdbc:oracle:thin:@1.1.1.1:1521:MYDB" /> <property name="hibernate.dialect" value="org.hibernate.dialect.OracleDialect"/> <property name="hibernate.connection.driver_class" value="oracle.jdbc.driver.OracleDriver" /> <property name="hibernate.connection.username" value="USERNAME" /> <property name="hibernate.connection.password" value="PASSWD" /> <property name="hibernate.hbm2ddl.auto" value="update"/> </properties> </persistence-unit> </persistence> / Thanks Kavita -- View this message in context: http://servicemix.396122.n5.nabble.com/How-to-resolve-dependencies-related-to-hibernate-in-servicemix-4-4-2-tp5714210.html Sent from the ServiceMix - User mailing list archive at Nabble.com.
