Hi,

I have created bundle for property file (sample.properties).In pom.xml, I export the package.

I can able to successfully call that property file from another bundle.For that I used spring DSL. Below are the code to import that property file in camel-context.xml.

I can able to read the property file which defined in sample.properties.

IN ONE case am using Java DSL.There am facing the issue.I tried to call it as follows

InputStream propStream = BundleContext.class.getResourceAsStream("com/my/sample/test/sample.properties");

Properties props = new Properties();

             try {

                 props.load(propStream);

                 propStream.close();

             } catch (IOException e) {

                 e.printStackTrace();

             }

             SAMPLE_URL_1 = props.getProperty("sample.url");

InputStream propStream = PropertyPlaceholderConfigurer.class.getResourceAsStream("com/my/sample/test/sample.properties");

    try {

                 props.load(propStream);

                 propStream.close();

             } catch (IOException e) {

                 e.printStackTrace();

             }

             SAMPLE_URL_1 = props.getProperty("sample.url");

But both are failed.

Could any one help me to call property file in budle from java dsl.

Regards,

Saji

Hi Freeman,

Thanks for your reply.

I tried as you said..

Please find below steps what i did :

1. I put common.properties file in $SMXHOME/etc/ folder.

2. In camel-context.xml(Spring DSL) i defined '*<osgi:reference id="configAdmin" interface="org.osgi.service.cm.ConfigurationAdmin" />*'

camel-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:camel="http://camel.apache.org/schema/osgi"

xmlns:ctx="http://www.springframework.org/schema/context"

xsi:schemaLocation="

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd

">

<import resource="classpath:org/apache/servicemix/camel/nmr/camel-nmr.xml"/>

*<osgi:reference id="configAdmin" interface="org.osgi.service.cm.ConfigurationAdmin" />*

<camel:camelContext id="myCamel" xmlns="http://camel.apache.org/schema/spring">

<endpoint id="sampleFileEndPoint" uri="$"/>

<!--

| Define routing rules.

|-->

<route>

<from ref="sampleFileEndPoint" />

</route>

</camel:camelContext>

</beans>

After install the bundle and when i tried to start that osgi bundle, am getting following exception...

karaf@root> Exception in thread "SpringOsgiExtenderThread-62" org.apache.camel.RuntimeCamelException: org.apache.camel.FailedToCreateRouteException: Failed to create route route5: Route[[From -> [To[log:com.vzb.ram.... because of Error creating bean with name 'sampleFileEndPoint': Fac toryBean threw exception on object creation; nested exception is org.apache.camel.NoSuchEndpointException: No endpoint could be found for: ${SampleFileEndP oint}, please check your classpath contains the needed camel component jar. at org.apache.camel.util.ObjectHelper.wrapRuntimeCamelException(ObjectHelper.java:1055) at org.apache.camel.spring.SpringCamelContext.onApplicationEvent(SpringCamelContext.java:103) at org.apache.camel.spring.CamelContextFactoryBean.onApplicationEvent(CamelContextFactoryBean.java:593) at org.springframework.context.event.SimpleApplicationEventMulticaster$1.run(SimpleApplicationEventMulticaster.java:78) at org.springframework.core.task.SyncTaskExecutor.execute(SyncTaskExecutor.java:49) at org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent(SimpleApplicationEventMulticaster.java:76)

-

Then I added the following bean...

<bean id="placeholderConfig" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"/>

This time while i start up the osgi bundle there is no exception in kernal. But it throws an exception in servicemix.log.

17:49:21,328 | ERROR | xtenderThread-63 | ContextLoaderListener | BundleApplicationContextListener 50 | Application context refresh failed (OsgiBundleXmlApplicationContext(bundle=myBundle, config=osgibundle:/META-INF/spring/*.xml)) org.springframework.beans.factory.BeanDefinitionStoreException: Invalid bean definition with name 'sampleFileEndPoint' defined in null: Could not resolve placeholder 'SampleFileEndPoint' at org.springframework.beans.factory.config.PropertyPlaceholderConfigurer.processProperties(PropertyPlaceholderConfigurer.java:268) at org.springframework.beans.factory.config.PropertyResourceConfigurer.postProcessBeanFactory(PropertyResourceConfigurer.java:75) at org.springframework.osgi.context.support.AbstractDelegatedExecutionApplicationContext.invokeBeanFactoryPostProcessors(AbstractDelegatedExecutionApplicationContext.java:479)

Please give me the steps to read the properties from etc/common.properties file.

++++++++++++++++++++++++++++++++++++++++++++++++++++++

++++++++++++++++++++++++++++++++++++++++++++++++++++++

Also, please provide code snippet to read the property from java DSL.

As you said i implement the interface 'BundleContextAware' and override the method setBundleContext...

Further i dont know how to read the property file using above.

Thanks

Saji
