Declared Exceptions and Chained Exceptions

[Matt Raible <ma...@raibledesigns.com>]

Can I use Declarative Exceptions and Chained Exceptions at the same
time?  I'd love to be a able to specify a list of exceptions in my
struts-config.xml, and have those errors stacked on each other.
Currently, I'm rendering ChainedExceptions using the following, and
would love to do it in struts-config.xml instead.  Any advice or
suggestions are appreciated.

try {
    UserManager mgr =
        new UserManagerImpl(
            (String) ctx.getAttribute(Constants.DAO_TYPE));
    UserForm user = mgr.getUser(username);
    session.setAttribute(Constants.USER_KEY, user);
} catch (Exception e) {
    log.error("Error getting user's information " + e);
    e.printStackTrace();
    ActionErrors errors = new ActionErrors();
    errors.add(
        ActionErrors.GLOBAL_ERROR,
        new ActionError("errors.general"));
    StringBuffer sb = new StringBuffer();
    if (e.getCause() == null) {
        sb.append(e.getMessage());
    } else {
        while (e.getCause() != null) {
            sb.append(e.getMessage());
            e = (Exception) e.getCause();
        }
    }
    errors.add(
        ActionErrors.GLOBAL_ERROR,
        new ActionError("errors.detail", sb.toString()));
}

Thanks,

Matt
