Netbeans Platform access DTD from other module

Question

We're writing a Netbeans platform app, and we want to add some data as an XML files. Also we want to have a DTD for that files, and we want to put it in one of our main modules, as it should be used in different places and dependent XML files will be in a different modules. Now how can I point to that DTD from XMLs in another modules?

I'll be very thankful for any advice.

Also maybe mentioned above idea is bad but that's all I could think about, so critique is welcomed.

Answer 1

Say you have a module file structure like this

MyModule
  com.mydomain.mypackage
    layer.xml
    main.dtd

And layer.xml contains

<filesystem>
    <folder name="MyDTDs">
        <file name="myMainDTD" url="main.dtd"/>
    </folder> 
</filesystem>

Then you can get a FileObject to the dtd file from another module by doing

FileObject root = FileUtil.getConfigRoot();
FileObject myDTDs = root.getFileObject("MyDTDs");
if (myDTDs != null) {
    FileObject mainDTD = myDTDs.getFileObject("myMainDTD");
}

And from the FileObject you can get an InputStream and so forth.
