Re: Roundtripping using Digester and Betwixt

[snip] How can I instruct Betwixt (the BeanWriter instance, I think) to write out the info so that it matches the pattern that I'm using when reading? Perhaps I should just be using Betwixt for both reading and writing, but I'd still like to be able to set things up, explicitly, so that the XML format for a given class is knowing ahead of time (so the format for reading and writing is the same). Please reply, if someone has an idea about this. Thanks! Yes you should probably be using Betwixt for both reading and writing (betwixt uses Digester internally for reading anyway). You can create a .betwixt file for a class to define how you want the xml to be written/read, eg for class example.foo.Bar, create a file example.foo.Bar.betwixt containing the necessary definitions. This file is used automatically when an object is *written to xml* by betwixt. When reading xml, you do need to register the classes that you expect to be reading from the xml; betwixt then finds the appropriate .betwixt files for them to use when reading the xml in. See the betwixt documentation for further details; the examples show how to do all this.

[chain] Strategies for alternate paths through a chain
Spring 1.2.1, commons-chain 1.0, JDK 1.4.2, WebLogic 8.1.4. I have a relatively simple chain in a large Spring application context. I've realized that somewhat near the end of the chain, I need to be able to skip one or more commands, and at least one of those commands is a reusable parameterized component, so I can't just put a chain-specific flag into the context to make the skippable command(s) be a noop. So, what are my options for following alternate paths through a command chain? The point where I determine I'll need to skip 1 or more commands is in a chain-specific class (not a reusable component), so I can write code in there to do whatever I need. I see that within the code of a command, I can get the Catalog through the static method in CatalogFactory, and then I can get a specific command (I assume that the id property in the context is the name the API refers to?), which I could then execute, and then perhaps return true from the calling command. If in that code of the command, I determine I need to skip the next command, but execute the last two commands of the chain, could I wrap the last two commands in a nested command (a ChainBase), so I could then get that ChainBase from the catalog and execute that? If I didn't need to skip the command, would it execute into the nested command normally? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
[Id commons] Configuration howto
Hello, I'm doing an application on Java but I'm not an expert in it, and I want to use the Id component, but I don't know how to configure my system(if I have to) for using it or where to put the component files. Also I want to be sure that I have all the files belonging to the component. I downloaded all the files from the site http://svn.apache.org/viewvc/jakarta/commons/sandbox/id/trunk/ is that correct? I'll hope you help me, because I really want to use this component. Thank you,
