problem downloading from alfresco repository using java code

[hclpower]

hi there!

Im facing download problem from alfresco repository.
my different methods of uploading is successful, but while downloading im stucking up at this code :

downloadAction code:

Content[] readResult =  WebServiceFactory.getContentService().read(new Predicate(new Reference[]{contentReference}, storeRef, null), Constants.PROP_CONTENT);‍

and the error it throws is:

10:38:33,506 ERROR [STDERR] AxisFault

Try using following code:

Reference referencePath = new Reference(WORKSPACE_STORE, null, "/app:company_home/cm:flow.txt");
InputStream is = ContentUtils.getContentAsInputStream(content)
…‍‍‍

I think that u are missing "cm:" in front of "flow.txt".

I changed my code to something like following :

ContentServiceSoapBindingStub contentService = WebServiceFactory.getContentService();
System.out.println("ISO9075.encode(fileName)"+ISO9075.encode(fileName));
                Reference contentReference = new Reference(STORE,null,parentSpace+"/cm:"+fileName);// Reference contentReference = new Reference(STORE,null,parentSpace);
System.out.println("UUID IS …….."+contentReference.getPath());
System.out.println("3"+fileName);               
                Content[] readResult = contentService.read(new Predicate(new Reference[]{contentReference}, STORE, null), Constants.PROP_CONTENT);
