Is it possible to use spring inside war bundle on felix? I use spring 3.0.5 with felix on glassfish 3.1
I tried to enter component-scan tag inside OSGI war bundle in felix, and I'm getting the below exception.
I saw that a similar bug was solved for Equinox, and what about felix? Is there a workaround or solution to this problem?
P.S: the same exception is thrown if I define path with * in web.xml contextConfigLocation, for example:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:META-INF/spring/*.xml</param-value>
</context-param>

thank you for any tip
There are 2 workarounds I found to solve it. Still I'll be glad to hear a real solution for felix.
The workarounds are:
Use equinox instead of felix :)
(an ugly one) Create a temporary folder and extract all the classes into it. Create a class org.eclipse.core.runtime.FileLocator with a function
public static URL resolve(URL url) throws IOException
and return the url of content from this folder, for example:
String path = url.getPath();
String str;
if(path.contains("com")){
str = path.substring(path.indexOf("com"));
}
return new URL("file:\\c:\\temp_classes\\"+str);
A slightly more elegant solution if you don't mind tying yourself to Felix.
package org.eclipse.core.runtime;
import java.net.URL;
import org.apache.felix.framework.BundleRevisionImpl;
import org.osgi.framework.Bundle;
import org.osgi.framework.FrameworkUtil;
public class FileLocator {
private FileLocator() {}
public static URL resolve(URL url) {
if(url == null) {
return null;
}
Bundle bundle = FrameworkUtil.getBundle(FileLocator.class).getBundleContext().getBundle();
BundleRevisionImpl bundleRevision = bundle.adapt(BundleRevisionImpl.class);
return bundleRevision.getLocalURL(url.getPort(), url.getPath());
}
}
This requires that you export the framework on Felix startup with the following parameter:
-Dorg.osgi.framework.system.packages.extra=org.apache.felix.framework

I'm pretty new to using Camel and ActiveMQ. I'm trying to run a simple code from Eclipse, without using Maven. But, it fails during Bean initialization. From the error, it seems its due to the JAR version differences, but i m failing to locate it. Kindly help me resolve this .

CamelContext ctx = (CamelContext) aContext.getBean("mycamelTemplate", CamelContext.class);
ctx.addRoutes(new BuildTwitterComponent());
ctx.start();

I have spring.jar.2.5.6 and camel-spring-2.11.1 JAR in the classpath. Pls suggest what am i missing here.
Thanks!
GR
Camel 2.11.1 uses Spring 3.2.3.RELEASE
Also, you'll need to have ActiveMQ 5.8.0 jars (activemq-camel, etc) in your path as well to find the org.apache.activemq.camel.component.ActiveMQComponent class
I am working on a Spring Project:Common that uses a combination of Annotaions and Spring IOC in XML.
I have a common.jar which contains Common classes used by various projects.
And I have another Spring Project:WebService that refers to the beans defined in common.jar.

Well add this to applicationContext.xml
<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/>
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>
I am trying to load a property file (.properties) into my class, I am following the example in another thread here: How to read values from properties file? - but it's not working for me.
here's my quick implementation:
applicationContext.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"

<!-- Load up properties -->
<context:component-scan base-package="com.test"/>
<context:property-placeholder location="file:///C:/dev/workspace/test-project/src/main/resources/appconfig.properties"/>
</beans>
TestConfig.java
#Component
public class TestConfig
{
#Value("${test.key1}")
private String key1;
public String getKey1()
{
return key1;
}
}
src/main/resources/appconfig.properties
test.key1=value
test.key2=value
Starting up my tomcat, I see the following in my log:
00:11:41,985 [localhost-startStop-1] INFO PropertyPlaceholderConfigurer - Loading properties file from URL [file:/C:/dev/workspace/test-project/src/main/resources/appconfig.properties]
However, when I do getKey1(), I get "null".
What am I missing?
Question 2: If I use "classpath":
<context:property-placeholder location="classpath:appconfig.properties"/>
Which directory is that referring to? root of WEB-INF/classes?
I hope you are using IDE like Eclipse.
Check if the resources directory is added to the classpath and it includes all the files within it as well , if eclipse you have to add . in the inclusion pattern
build your project and check if the the property file is available in WEB-INF/classes
To answer your second question
classpath:appconfig.properties -Yes spring will look for the file in WEB-INF/classes
This was silly ...
When I get the TestConfig object, I was doing:
TestConfig config = new TestConfig();
config.getKey1();
Which of course the config object is a brand new object and never instantiated (or injected) with anything.
Instead I am injecting it so it got initialized by Spring framework:
#Autowired
private TestConfig config;
As explained here and here it is quite clear how to do it but still can't seem to make it work.
I simply like to use the #Value annotation in order to inject a property to a spring bean. I created a basic spring MVC project with one controller and one bean.
Here is my application context:

<!-- Properties -->
<bean id="props"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="classpath:fatProperties.properties" />
</bean>
</beans>
I have one bean called Configuration:
package me.co.fatsecret;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
#Component
public class Configuration {
/*--- Members ---*/
#Value("${api_key}")
protected String API_KEY;
#Value("${api_secret}")
protected String API_SECRET;
#Value("${api_url}")
protected String API_URL;
/*--- Constructors ---*/
public Configuration() {
}
/*--- Getters & Setters ---*/
public String getAPI_KEY() {
return API_KEY;
}
public void setAPI_KEY(String aPI_KEY) {
API_KEY = aPI_KEY;
}
public String getAPI_SECRET() {
return API_SECRET;
}
public void setAPI_SECRET(String aPI_SECRET) {
API_SECRET = aPI_SECRET;
}
public String getAPI_URL() {
return API_URL;
}
public void setAPI_URL(String aPI_URL) {
API_URL = aPI_URL;
}
}
Now I have only one controller, injected with this Configuration class and as I call this controller I see that the values in the Configuration class are not populated right.
My properties file is located under the resources folder (src/main/resources) and is a part of my classpath (done by default since this is a maven project). Here it is:
api_url=http://platform.fatsecret.com/js?
api_key=SomeKey
api_secret=SomeSecret
The file name is fatProperties.properties.
As I debug my server when calling the controller I see that the content of the Configuration class is:
${api_key}
${api_secret}
${api_url}
This is the actual value of the Strings, wich means that the vales from the properties file are not getting injected for some reason.
Am I missing something here?
UPDATE1: I replaced the PropertyPlaceholderConfigurer bean with:
<context:property-placeholder location="classpath:fatProperties.properties"/>
Getting the same result
Ok, got it!
I'm using a spring MVC project, which means I have a separated context for my web layer (the controllers). The "Configuration" bean which hods the properties using the #Value annotation is injected to a controller. My property-placeholder is defined within my root-context hence it cannot be seen from my controller. To resolve the issue I simply added the property-placeholder definition to my DispatcherServlet context and it works like a charm :)
Add this to your application context file:
<context:property-placeholder location="classpath:fatProperties.properties" />
Try
#Value("#{props['api_key']}")
private String apiKey;
I was wondering if there is a way to do the following:
have my wep app startup with its servle-context.xml
When, at a certain point, one particular bean in this xml config is instantiated, it will add it's own xml configuration to the application context (or to a child perhaps?).
I'm asking this because I want to pack some functionality in a stand alone library and then reuse it in different projects, so that initializing a bean of this library will load its xml config.
What I wrote is:
public class IrisLibHelper {
ApplicationContext context;
ApplicationContext irisContext;
#Required
#Autowired
public void setContext(ApplicationContext ctx){
this.context = ctx;
ClassPathXmlApplicationContext xap = new ClassPathXmlApplicationContext(ctx);
xap.setConfigLocation("classpath:com/dariodario/irislib/xmldefs/irisconfig.xml");
this.irisContext = xap;
}
public ApplicationContext getIrisContext() {
return irisContext;
}
public void setIrisContext(ApplicationContext irisContext) {
this.irisContext = irisContext;
}
}
and the irisconfig.xml is:
<?xml version="1.0" encoding="UTF-8"?>

The problem is that it doesn't seem to scan the com.dariodario.iris.controllers package, in fact the controllers don't get mapped! (I've logging debugging on and I don't seen anything).
Why not use the tag <import resource="classpath:applicationConfig.xml" /> ? You can load a spring configuration file which is in jar. In a jar, the Spring XML configuration is always at the root. But if not, you can use this notation: <import resource="${configurablePath}/applicationConfig.xml" /> where configurablePath can be reach by a property place holder or other.
I think this way is cleaner than merging two Spring context.
