WinRun4J - can't load library jars

Question

I'm trying to execute my Java program as windows service using WinRun4J. The service is correctly created and run until it stop because of a ClassNotFoundException:

org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Failed to import bean definitions from relative location [appContext-webServices.xml]

I suspect WinRun4J isn't loading my lib jars that are in lib folder. My application working dir is like this:

application directory
     -> bin directory
     -> lib directory

the main application jar is in bin folder, the others jars are in lib folder. This is my servico.ini file, used by WinRun4J:

vm.version.min=1.6
single.instance=process
service.class=br.com.gep.sped.extrator.AppServico
service.id=AgenteWIN
service.name=Agente Win
service.description=Agente de extração dos dados SPED.
classpath.1=*.jar
classpath.2=../lib/*.jar
vmarg.1=-Xmn100M
vmarg.2=-Xms500M
vmarg.3=-Xmx500M

I've tryied a lot of variations in classpath.2 without success.
What I'm doing wrong?

Answer 1

Being Windows you probably need to use backslashes instead of forward slashes

classpath.2=..\lib\*.jar

If that isn't sufficient try adding

working.directory=.

to ensure that the relative paths are resolved against the right base directory. If all else fails you could add a manifest to your main JAR file with a Class-Path that enumerates all the ../lib/file.jar files and do away with classpath.2 altogether.

Edit: seeing that stack trace it looks like WinRun4J is not setting up the thread context classloader properly. Try adding

Thread.currentThread().setContextClassLoader(
    AppServico.class.getClassLoader());

to the top of your serviceMain, before you instantiate anything Spring/CXF related.
