hi, guys
i'm a new developer for java . and i want to debug the activemq-core code
when i running my test code. but i have met some resource file problem.i do
these
1. download the source code from web site. unzip it
2. uses the eclipse create a project name "Activemq-core" and copy the
source folder's org folder in src folder. copy the resource folder to
Activemq_core folder
the my activemq-core project folder list is
src---org---apache--activemq--
advisory.
borker.
......
resources---META-INF
activemq.xsd
...
3. i refer to another jar file and another library for this project. and i
can build it.
4 i create a new test project TestActiveMQCore project and write a test
class .and refer to ActiveMQ-core source code . other project i refer to
jar file (ActivemQ binrary folder /lib folder files)
public void Main()
{
ActiveMQConnectionFactory cf = new ActiveMQConnectionFactory(
"tcp://localhost:61616");
Connection con = cf.createConnection();
con.start();
}
5 i copy the the test folder's resources folder into TestActiveMQCore
project. and copy the log4j.properties file under eclipse-resources
folder into resources folder.
6 running my test class . i can debug into ActiveMQ_core source . but it
can't get the config file in
ActiveMQPrefetchPolicy.java
public class ActiveMQPrefetchPolicy implements Serializable {
private static final Log LOG =
LogFactory.getLog(ActiveMQPrefetchPolicy.class); //here i can get log4
config file
.....
}
**-------------------------------------------------------
there is a problem why it can't load the log4 config . i copy the
log4j.properties into resources folder
**-------------------------------------------------------
7. continue running the test code. and create a connection debug here
appear excetipn
org\apache\activemq\util\FactoryFinder .java
private Class newInstance(Properties properties, String propertyPrefix)
throws ClassNotFoundException, IOException {
String className = properties.getProperty(propertyPrefix + "class");
if (className == null) {
throw new IOException("Expected property is missing: " +
propertyPrefix + "class");
}
Class clazz = null;
ClassLoader loader = Thread.currentThread().getContextClassLoader();
if (loader != null) {
try {
clazz = loader.loadClass(className);
} catch (ClassNotFoundException e) {
// ignore
}
}
if (clazz == null) {
clazz =
FactoryFinder.class.getClassLoader().loadClass(className);
}
return clazz;
}
**-------------------------------------------------------
loader get null .
**-------------------------------------------------------
if i switch using ActiveMQ-Core jar file than it running OK.so i want to
know how to deploy the config i.any idea?
thanks
