Since the digester was born here, maybe someone knows the answer to this. I'd be happy to get a response over on commons-user or here. I'll reply to my own thread if someone replies here, citing it. ::: I'd like to invoke a method on the current top-of-the-stack object and pass a static string value to it, like this: digester.push(new MyBean()); digester.addCallMethod("/Foo/Bar", "setAttribute", 2, new Class<?>[] { String.class }); digester.addCallParam("/Foo/Bar", 0, "MyStaticString"); digester.addCallParam("/Foo/Bar", 1, "attrName"); digester.parse(...); When encountering /Foo/Bar, I'd like this to be called: myBean.setAttribute("MyStaticString", [value of attribute "attrName"]) Is that kind of thing possible? I thought I might pull a fast one and push the value "MyStaicString" onto the stack and call: digester.addCallParam("/Foo/Bar", 0, true); But I it seems I can't push a value onto the stack when a specific path is seen: only statically at some specific point (like before parsing begins).You have not said what version you are using.
You are absolutely right. My apologies. My version of commons-digester is 3.2.
Looking at Apache Commons Digester 3.2 source code and searching for "peekParams()" calls (the API used to access the list of parameters created by CallMethodRule): 1. I see that there exists a ObjectParamRule class that allows injecting arbitrary values as parameters for the call. It is documented as "@since 1.4". 2. There exists a Digester.addObjectParam() method. It is "@since 1.6".
Awesome. That's exactly what I was looking for. Thanks! -chris --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
