javaconfig with custom loadeer?

[watzlaw wutz]

Hi,

I would like to create a springcontainer using javaconfig with a custom class loader. This is what I've tried:

  System.err.println(RnaCompoundDBConfig.class.getName());
        
        JavaConfigApplicationContext applicationContext = new JavaConfigApplicationContext();

        // here I set my custom classloader which is url-class loader
        applicationContext.setClassLoader(this.getClass().getClassLoader());
        applicationContext.addConfigClass(RnaCompoundDBConfig.class);
        applicationContext.refresh();

However I get an exception when doing the refresh:

java.io.FileNotFoundException: Class file [de/mpicbg/tds/rm/hcstools/RnaCompoundDBConfig.class] not found). Check the log messages... (ProcessThread.run())
  java.lang.RuntimeException: java.io.FileNotFoundException: Class file [de/mpicbg/tds/rm/hcstools/RnaCompoundDBConfig.class] not found

      org.springframework.config.java.context.JavaConfigApplicationContext.invokeBeanFactoryPostProcessors(JavaConfigApplicationContext.java:121)
      org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:362)
      de.mpicbg.tds.rm.hcstools.AnnotateRNAScreen.setupService(AnnotateRNAScreen.java:50)

The AsmUtils seem to ignore my custom classloader. What could be my mistake?

Any help is appreciated.

Best, Holger

First, strongly consider using Spring 3.0 and its AnnotationConfigApplicationContext. It replaces the JavaConfig project and its JavaConfigApplicationContext.

Second, this will probably be a hard limitation of the way that things work right now. ASM is assuming that the class is loadable as a classpath resource. If you're fetching it via a URL, that violates the assumption.

Add an issue for this in JIRA if you like. It's conceivable that we could accommodate this, because at the end of the day ASM really just needs an input stream.
