RE: Attribute question for Commons Digester
You mean: digester.addObjectCreate(article, Article.class); digester.addSetProperties(article, id, id); Yup. I've tried that. The actual value of the id field in the XML _1234 is ignored and 0 is set on the Article id field instead. I assume that this is because of the underscore in the id field. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of James Carman Sent: 29 June 2007 11:48 To: Jakarta Commons Users List Subject: Re: Attribute question for Commons Digester Have you tried an ObjectCreate followed by a SetProperties?

RE: Attribute question for Commons Digester
Also, does the plugin class need to implement a specific class? It doesn't look that way in the examples, and there doesn't appear to be any way to get the Digester to call a specific method in the plugin class. I have the feeling I have misunderstood something here.. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of James Carman Sent: 29 June 2007 11:59 To: Jakarta Commons Users List Subject: Re: Attribute question for Commons Digester Yeah, I didn't notice the _ (or read the rest of the request). You'll need a custom rule here to convert that value, otherwise SetProperties would work (and you don't need to specify id/id because it'll match the properties to the attributes if they match exactly).

RE: Attribute question for Commons Digester
I have no idea why the underscore is there; but its there in the source XML and my code has to deal with it *shrug*. I do realise that I need a custom rule - but I can't seem to get it working. Say I have a rule called ArticleIDTransform, then I do something like: PluginCreateRule pcr = new PluginCreateRule(ArticleIDTransform.class); digester.addRule(article, pcr); digester.addSetProperties(article, id, id); The rule doesn't fire..what I am doing wrong?
