Question

I have config.properties in my OSGi bundle. but the OSGi bundle can not read it.

Application context refresh failed (OsgiBundleXmlApplicationContext(bundle=dao, config=osgibundle:/META-INF/spring/*.xml))
org.springframework.beans.factory.BeanInitializationException: Could not load properties; nested exception is java.io.FileNotFoundException

I am using Spring to read the config.properties

<bean id="propertyConfigurer"
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="location" value="config.properties" />
</bean>

It seems like the OSGi only reads the .xml file.
Does someone has any idea?

You have to specify the correct resource for your value property.
There are some built in implementations, like:

• ClassPathResource: value="classpath:/META-INF/config.properties"
• FileSystemResource: value="file:C:/foobar/config.properties"

If you want to place the file outside the library you can use a system property (e.g. -DpropertyFile=C:/loremIpsum/config.properties) to specify the path, like

value="file:${propertyFile}"

since Spring 3.0.? even with default value

value="file:${propertyFile:C:/foobar/config.properties}"

(Have a look at your OSGi framework on how to set a system property. I am also not sure if the ClassPathResource works well / is recommended in OSGi environments.)
