Hello,

Below is the code I have written to upload a file from my local system to Alfresco repository..

ApplicationContext context = new ClassPathXmlApplicationContext("classpath:alfresco/application-context.xml");
Repository repository = (Repository)context.getBean("JCR.Repository");

// login to workspace (here we rely on the default workspace defined by JCR.Repository bean)
Session session = repository.login(new SimpleCredentials("admin", "admin".toCharArray()));

try
{
// first, access the company home
Node rootNode = session.getRootNode();
Node companyHome = rootNode.getNode("app:company_home");

FirstJCRClient t= new FirstJCRClient();
t.tCheckin();

}

catch (Exception e)

finally
{
session.logout();
System.exit(0);
}
}
public void tCheckin()

writer.putContent(contentStream);
}
catch (Exception e)
{
e.printStackTrace();
}
}
}

Its failing exactly at this line of my code "FileInfo fileinfo = fileFolderService.create(root, file.getName(), ContentModel.TYPE_CONTENT);".

Please if you can provide some suggestions here, will be of much appreciation!

Thanks
Amit.
