Jonas Bengtsson updated CAMEL-4213:
-----------------------------------
Description:
When using the following simple route, the entity classes can't be found:
{code}
public void configure() throws Exception {
from("direct:test-in").to("jpa:mypackage.MyEntity1");
from("jpa:mypackage.MyEntity2").to("log:test-out");
}
{code}
The error message is:
09:43:55,417 | WARN | rint Extender: 3 | ObjectHelper |
g.apache.camel.util.ObjectHelper 698 | 78 - org.apache.camel.camel-core -
2.7.2 | Cannot find class: mypackage.MyEntity1
09:43:55,467 | WARN | rint Extender: 3 | ObjectHelper |
g.apache.camel.util.ObjectHelper 698 | 78 - org.apache.camel.camel-core -
2.7.2 | Cannot find class: mypackage.MyEntity2
followed by many warnings about that the entityType is not known for the
consumer.
The errors only occur when using blueprint to bootstrap the route. When using
spring-dm everything works fine. The entity classes are located in the same
bundle as the route. My guess is that it uses the wrong classloader.
JPA works fine otherwise. It is only the camel-jpa component I have problems
with. camel-jpa is a very spring-centric module, using a spring
TransactionManager and all, so I hope that my use case makes sense.
For completeness here is my blueprint-file:
{code}
<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0";
default-activation="eager"
xmlns:jpa="http://aries.apache.org/xmlns/jpa/v1.1.0";>
<camelContext xmlns="http://camel.apache.org/schema/blueprint";>
<package>mypackage</package>
</camelContext>
<bean id="jpa" class="org.apache.camel.component.jpa.JpaComponent">
<property name="entityManagerFactory"
ref="entityManagerFactory" />
<property name="transactionManager" ref="transactionManager" />
</bean>

class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory"
ref="entityManagerFactory" />
</bean>
<reference id="entityManagerFactory"
interface="javax.persistence.EntityManagerFactory"
filter="(osgi.unit.name=myunit)" />
</blueprint>
{code}
The EntityManagerFactory is created by Aries Jpa, but it shouldn't be relevant
for the question.
