newbie , exception trying to retrieve a newly created uri object

[Jason Coelho <ja...@netymology.com>]

Hi,

I'm new to Slide and I've been trying to create an object using the Slide
API.

I've setup my code to use JDBC as a store for both the descriptor and the
content. In my code, the
object gets created and its descriptors are stored in the table, however the
object's content does'nt
get stored any where.( I've checked for the content in the revisioncontent
table , and there are no
entries ). Furthermore I get an revisionNotFound exception when I try to
retrieve the object.

Am I doing anything wrong ? Can anyone give me any suggestions ? Thanks in
advance.

Jason.

The following is an excerpt from my code :

----------------------------------------------------------------------------
--------------------------
//....... slideStruct, content , token initialized

String uri  = "/files/test.txt";
String data = "test test test";

SubjectNode subject = new SubjectNode();
slideStruct.create(token, subject,uri);

 // Creating a versioned revision descriptors
content.create(token,uri, true);

NodeRevisionDescriptors revisionDescriptors = content.retrieve(token,uri);
NodeRevisionDescriptor revisionDescriptor = new NodeRevisionDescriptor(0);

revisionDescriptor.setContentLength(data.length());
revisionDescriptor.setProperty("revision", "1");

NodeRevisionContent nodeRevisionContent = new NodeRevisionContent();
nodeRevisionContent.setContent(new StringReader(data));

content.create(token,uri, revisionDescriptor, nodeRevisionContent);

// testing retrieval of content

revisionDescriptor = content.retrieve(token, revisionDescriptors);

NodeRevisionContent testContent =
content.retrieve(token,uri,revisionDescriptor);  // THROWS AN EXCEPTION HERE
FOR SOME REASON
StringReader testReader = (StringReader)testContent.readContent();
log.info("Content : " + testReader.toString());

----------------------------------------------------------------------------
---------------------------

The code above throws the following exception. (Domain.xml follows)
