Re: Spring & Blueprint, bean reference sharing

[Jean-Baptiste Onofré]

Hi,

no it's not possible, it's two different containers.

However, you can expose a bean as a service in blueprint:

<service interface="..."/>

and use this service in Spring using spring-dm:

<osgix:reference id="..." interface="..."/>

Hi,

Is it possible to reference to blueprint bean in a spring context.
The idea is to use blueprint configuration properties and use it for my
datasource in spring context.


In my context.xml

<?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:kie="http://drools.org/schema/kie-spring";
        xsi:schemaLocation="
        http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://drools.org/schema/kie-spring
http://drools.org/schema/kie-spring.xsd";>



     <bean id="myEmf"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
         <property name=&quot;dataSource&quot; ref=&quot;&lt;b>jbpm-ds*"/>
         <property name="persistenceUnitName"
value="org.jbpm.persistence.jpa.local"/>
     </bean>

</beans>


in my blueprint.xml
<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0";
xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.1.0";

        <cm:property-placeholder id="databaseProperties"

                        <cm:property name="url"

                        <cm:property name="jndiName" value="jdbc/mysqlds"/>
                        <cm:property name="driverClassName"

                        <cm:property name="username" value="root"/>
                        <cm:property name="password" value=""/>
                        <cm:property name="maxActive" value="200"/>
                </cm:default-properties>
        </cm:property-placeholder>

        <bean id=&lt;b>"jbpm-ds"* 
class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
                <property name="url" value="${url}"/>
                <property name="driverClassName" value="${driverClassName}"/>
                <property name="username" value="${username}"/>
                <property name="password" value="${password}"/>
                <property name="maxActive" value="${maxActive}"/>
        </bean>

</blueprint>


gives the  error
