Subject Get versioned file data
Date Thu, 01 Mar 2007 16:42:37 GMT



Hello,
 
I'm having trouble to get the file data of a specific version of a versioned file from the
repository.
 
What I do is the following:
- Create a jcr:content node of type nt:resource.
- Upload version 1.0 of the file to jcr:content
- Make the jcr:content versionable 
- Save and checkin
- Upload version 1.1 of the file to jcr:content
- Save and checkin
 
...
 
- Get the version history of jcr:content
- Get the version with the correct version name from the history
- Get the property jcr:data of the version throws a javax.jcr.PathNotFoundException
 
Getting the latest version works ok.
Listing the version history works ok.
 
I expect that the onParentVersion attribute of the common jcr:data property is COPY so that
should be ok.
 
Can anybody help me get the jcr:data property from a version?
 
 
Kind regards,
 
grizz
 
 
// Code to create the versions:
 
File file = new File(...);
MimeTable mt = MimeTable.getDefaultTable();
String mimeType = mt.getContentTypeFor(file.getName());
if (mimeType==null) mimeType="application/octet-stream";
Node version1Node = masterNode.addNode("jcr:content", "nt:resource");
version1Node.setProperty("jcr:mimeType", mimeType);
version1Node.setProperty("jcr:encoding", "");
version1Node.setProperty("jcr:data", new FileInputStream(file));
version1Node.setProperty("jcr:lastModified", Calendar.getInstance());
version1Node.addMixin("mix:versionable");
getSession().save();
version1Node.checkin();
 
file = new File(...);
mimeType = mt.getContentTypeFor(file.getName());
if (mimeType==null) mimeType="application/octet-stream";
Node version2Node = masterNode.getNode("jcr:content");
version2Node.checkout();
version2Node.setProperty("jcr:mimeType", mimeType);
version2Node.setProperty("jcr:encoding", "");
version2Node.setProperty("jcr:data", new FileInputStream(file));
version2Node.setProperty("jcr:lastModified", Calendar.getInstance());
getSession().save();
version2Node.checkin();
 
 
// Code to retrieve the latest version
 
Node contentNode = masterNode.getNode("jcr:content");
Property property = jcrVersion.getProperty("jcr:data"); // OK
InputStream stream = property.getStream();
 
 
// Code to retrieve the version with versionName
 
Node contentNode = masterNode.getNode("jcr:content");
VersionHistory history = contentNode.getVersionHistory();
Version jcrVersion = history.getVersion(versionName);
Property property = jcrVersion.getProperty("jcr:data"); // throws javax.jcr.PathNotFoundException
InputStream stream = property.getStream();
