wierd stack trace regarding parsing of struts.xml
So, when I restarted my struts2 app this afternoon I got complains about unable to load configuration. - [unknown location].

Probably trying to go out to the web for a DTD/XSD or something? Okay. It does appear to be finding the struts.xml file, and then timing out while trying to get something else over the network.

RE: wierd stack trace regarding parsing of struts.xml
Without knowing what you're specifying in your struts config it's tough to say. The times I've seen this are when there's a mismatch between what's in the config and what's in the libraries, like if it can't find the file locally, it goes on to the network. So, I think the issue is that I went from webwork to struts 2.3 on this app. I did the migration a while back, and the struts.xml files still worked fine even without migrating them to the new dtd ( declarations as well as actual structure ). But in on this one installation they fail. My theory is that if the internet is available, the struts.xml with xwork DTD will still work. This makes me think that the DTD resolution must have someone of resolving the dTD from the classpath prior to hitting the web URL, but I've not had a change to investigate that yet. - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
RE: wierd stack trace regarding parsing of struts.xml
IMO it just needs to match the DTD in the jar; as I said, I've generally seen this happen when there's a mis-match. In regards to your SO question, it would depend completely on the implementation and its configuration. Here's the one that doesn't work: ?xml version=1.0 encoding=UTF-8? !DOCTYPE xwork PUBLIC -//OpenSymphony Group//XWork 1.1.1//EN http://www.opensymphony.com/xwork/xwork-1.1.1.dtd; xwork But what do you think needs to match the jar file? I mean, struts2-core.jar doesn't contain xwork-1.1.1.dtd, but the xwork jar does . . . so why wouldn't it find it if it was just taking the xwork-1.1.1.dtd and checking the classpath. - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
Struts2 Rest Plugin
Hi! The docs for the REST plugin talk about how it builds on the Convention plugin ( sometimes it says code behind ). However, I don't see that using the REST plugin pulls in either of these plugins . . . in what sense does it build on them? Thanks, Chad

It's an interesting question, whether to make such things protected or private. When this is a part of framework it should be protected.

RE: implementaiton advise on custom TextProvider
ActionSupport#getTextProviderSupport() uses the TextProviderFactory to obtain it's instance of a support object. Since it uses the di to inject this into the factory, my custom version is correctly injected. However, I need to initialize my custom support object with a resource that it needs to conduct its business. Note, the default TextPRoviderSupport also needs a couple of resources, and those are initialized in the factory's createInstance( Class class, LocaleProvider provider ). So, while I've injected my own class, there doesn't seem to be a clean way to make sure that it's initialized properly. Should I extend the factory to handle my class and init it too? Doesn't seem very DI-ish . . . hardcoding type specific init logic, I mean. Or should I create an interceptor that will inject the correct resources into my text support object? ActionSupport base on property injections so you cannot base on anything which is injectable - you cannot use getTextProvider during initialisation time (construction time). You can implement your own ActionSupport with constructor injected TextProvider that should solve your problem. I'm not sure I follow you. Just for clarity, let me restate my problem. I have written a custom extension of TextProviderSupport. I want to have it injected as the framework's default TextProvider. I have achieved this by configuring it in struts.xml, declaring my implementation with a bean/ element and then setting the constant struts.xworkTextProvider to point at my bean. This works, but my implementation needs to be properly injected. Right now, it's being created with the default no-arg constructor. How can I best have my dependencies injected when the framework creates this bean? What are my options? I restate this because it seems that you are suggesting that I override the ActionSupport base class inorder to achieve this. This seems to me to be skipping the framework and simply creating and injecting my textprovider myself. Perhaps I misunderstand.
RE: implementaiton advise on custom TextProvider
If you are using the Spring Framework with your App, you should be able to define your TextProvider, with all it's dependencies, as a Spring Bean, then when you define the bean in Struts use the Spring Bean ID instead of using the full class name. Struts will use that Spring Bean in place of creating a new one. (*Chris*) So, you're saying that I can use the Spring plugin's Spring DI to configure framework components? I was under the impression that I had to use the framework's internal DI for such things . . . - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org

And, since I think I saw your name on some comments in the TextProvider, I wonder what constructors get invoked when the TextProvider is injected in the TextProviderFactory on ActionSupport.

DI supports also constructor injections, in the same way as property injection, just add @Inject to constructor. I'll check this out and get back to you.

These mocks would return a static data set, thus giving a predictable behavior against which we can build automated UI tests, provide a lightweight demo environment that doesn't need integrated into our rather large and complex real world data context, etc. My thoughts are to use the Spring integration to inject the mocks.
