Hi folks, About FORGE-2072. The problem is: We have this method: ErrorPageType getOrCreateErrorPage(); I’ll propose create a ErrorPageType getOrCreateErrorPage(String erroCode); The getOrCreteErroPage only check if web.xml has an error-page. This case, if I want do that: String errorLocation = getAccessStrategy().getWebPaths(web.getWebResource(ERROR_XHTML)).get(1); servletConfig.getOrCreateErrorPage().errorCode("404").location(errorLocation); servletConfig.getOrCreateErrorPage().errorCode("500").location(errorLocation); The shrinkwrap only put an error-page. This case, only 404. :) I fixed the FORGE-2072 with 2 methods because we need specify the WebAppDescriptor for servelet-api version, but this case erro-page is a common feature for two version of the api. No make sense sense to have two interface to this method. Look this: https://github.com/danielsoro/core/blob/FORGE-2072/javaee/faces/src/main/... I think better to have: WebAppDescriptorCommons - getOrCreateErrorPage() - createErroPage() - etc.. WebAppDescriptor30 extends WebAppDescriptorCommons - methodETC()… WebAppDescritptor31 extends WebAppDescriptorCommons - methodETC().. I don’t think a valid idea create a descriptor in forge if we have the shrinkwrap for that. IMHO. If it is a good suggestion, please.. open an issue in shrinkwrap. :) ​ -- Daniel Cunha (soro)
