Greetings,
I have been using the great software developed by the jakarta team for some time now.
I have found it very useful and I would like to contribute something. I'd like to
start with the commons digester and I have a specific idea. Let me know if people
would like to see this implemented. I think sending an email to this list is the
right way to get started but I appologize in advance if its not.
Here is a generic example of the problem I was trying to solve with digester and an
explanation of how the current code did not completely meet my needs (although I just
got started with digester so I may have overlooked something). The example is
building a GUI client for a program where the components used to build the client are
dynamically configured through an XML file. For simplicity I will not address the
possibility of components containing other components. Here is the xml:
<client>
<component classname="ComponentA"/>
<component classname="ComponentB">
<property name="SomeProperty" value="some value"/>
</component>
</client>
Now I'd like the digester to create a Client object when it encounters the <client>
tag. OK so far, I'll just use the standard ObjectCreateRule. The problem then
becomes that I know I will be encountering the "client/component" pattern but I don't
know what types of objects they are until runtime. I'd like to be able to specify the
classname somehow instead of hardcoding it in the rule setup (or dynamically creating
the rule). Also, each component may have zero or more properties to set but I don't
know the name of the properties in advance.
I have a specific solution in mind if the team is interested in hearing it (actually a
few possible solutions). If its determined that we don't want to do it there will be
no hard feelings. I definitely want to contribute something and all of the mailling
lists just say go ahead and jump in. If this is a "no go" then I'd be happy to help
in another capacity.
TIA for your feedback on this and keep up the good work!
