Using the slide API

["Thomson, Judi R" <Ju...@pnl.gov>]

I want to use the java API for slide directly instead of going through the DAV
interface.  I'm having trouble keeping straight the sequence of steps I need to
save a file.  There is a test program in the examples that loads the Domain.xml
file and shows me how to manipulate the structure, but I also need to be able to
save a file.

Basically I want to do something like:

create a new node in the structure
assign an input stream to that node
have it save the input stream to disk (based on the location identified in the
node)

We've been playing with the   token.getStructureHelper(), and
token.getContentHelper() methods, but we're just not getting the operations
right somehow and its not saving anything to disk.

Any suggestions appreciated!

Thanks

Judi

To be able to create a file on the hard disk you need the following entry in
the Domain.xml file.

    <contentstore name="file"
         classname="slidestore.file.FileContentStoreNoVersioning">
          <parameter name="rootpath">files</parameter>
    </contentstore>
             or
    <contentstore name="file"
         classname="slidestore.reference.FileContentStore">
          <parameter name="rootpath">files</parameter>
    </contentstore>

depending on whether you need versioning or not.
If you run the version example(in examples/version directory) with the above
entry for the
contentstore in the Domain.xml file and have  code which looks this in the
Test.java file you should see some files
being created on your hard disk.

         	String sample = "This is sample content being created";

            // get the revision descriptors for the node /test
            NodeRevisionDescriptors revisionDescriptors =
                content.retrieve(slideToken, "/test");
            // get the latest revision descriptor for the node /test
            NodeRevisionDescriptor  revisionDescriptor = content.retrieve
                (slideToken, revisionDescriptors);
		revisionDescriptor.setContentLength(sample.length());

		NodeRevisionContent chars = new NodeRevisionContent();
    		StringBufferInputStream reader =  new StringBufferInputStream(sample);
            // set the content
		chars.setContent(reader);

            // this should create the file on your hard disk
            content.create(slideToken, "/test", revisionDescriptor, chars);
