Subject problem attaching InputStream to jcr:data
Date Sat, 13 Jun 2009 22:44:33 GMT
Hi,
I have just downloaded the jackrabbit-1.5.5 jars and now when I am
trying to upload a file and attach it to jcr:data of nt:resource,
tomcat just throws an Exception - javax.servlet.ServletException:
Servlet execution threw an exception

May anyone point me where the problem is. Thanks in advance

I am using Tomcat 6 with jackrabbit 1.5.5, LocalfileSystem on a
Windows Box and DerbyPersistence Manager.

The code snippet for adding the node is as follows:

fileNode = baseNode.addNode("nameOfNode", "nt:file");
contentNode = fileNode.addNode("jcr:content","nt:resource");
_logger.debug(" setting the uploaded content in text node :
"+content.getMimeType());
_logger.debug(" setting the jcr:data ");
contentNode.setProperty("jcr:data", content.getContentStream());
_logger.debug(" set the jcr:data");
contentNode.setProperty("jcr:mimeType", content.getMimeType());
_logger.debug(" set the mime type : file : "+content.getContentStream());
_logger.debug(" setting the jcr:lastModified  ");
contentNode.setProperty("jcr:lastModified", Calendar.getInstance());
_logger.debug(" text node specific properties added successfully");

the Logger just prints "setting the jcr:data" and then the page
displays the above mentioned exception

Following is the snippet of the log
