Reinhard Poetz commented on COCOON-2080:
----------------------------------------
The problem is that if a class or an interface is loaded by the reloading
classloader and it is used to create a proxy from it, it can't be found. As a
workaround you can put the interface in a different module which is added as
normal dependency to your block (of course you mustn't add this other module to
your rcl.properties either).
> interface com.atn.htest.PersonDAO is not visible from class loader

> Key: COCOON-2080
> URL: https://issues.apache.org/jira/browse/COCOON-2080
> Project: Cocoon
> Issue Type: Bug
> Components: * Cocoon Core, - Build System: Maven
> Affects Versions: 2.2-dev (Current SVN)
> Reporter: Vladimir S Bronnikov
>
> I'm wrote my own Generator. The main purpose of them is to find "spring
> beans" in application context and invoke thier methods.
> WebApplicationContext ctx =
> WebAppContextUtils.getCurrentWebApplicationContext();
> Object bf = ctx.getBean(beanName);
> Method method = BeanUtils.findMethod(bf.getClass(), methodName,
> paramTypes);
> Object result = method.invoke(bf, paramValues);
> When I deploy my cocoon block first time - all fine.
> But if I change some resource and rcl do it's work, I get this error:
> org.springframework.beans.factory.BeanCreationException: Error creating bean
> with name 'com.atn.htest.PersonDAO' defined in URL
