Reading extended attributes from Java

Can anyone tell me how to read extended attributes for content store files from Java? I have searched around and can't find anything.

Do you have the CSSDK ? There is a class CSExtendedAttribute that will help

Thanks. We do have it and I saw it there, however, I saw no way calling say "getExtendedAttributes()" on a file and it would return an array or List of extended attributes. To use it you already have to know which extended attributes are there. I am trying to query which ones are present and then find out the values.

won't CSSimpleFile.getExtendedAttributes() work for you ?

That method takes a String[] argument. I don't know what goes in there since I don't have any API docs. I tried to look around for the API docs but can't locate any.

Hope this helps, if you have not found out already

CSSimpleFile sourceFile = (CSSimpleFile)client.getFile(new CSVPath(sourceFileName));
String[] eaArray = { "TeamSite/Templating/DCR/Type", "iw_form_valid" };
CSExtendedAttribute[] sourceEA = sourceFile.getExtendedAttributes(eaArray);

From Interwoven ContentServices SDK Release 7.2.1:

getExtendedAttributeNames
CSNameSizePair[] getExtendedAttributeNames(java.lang.String regex)
throws CSAuthorizationException,
CSObjectNotFoundException,
CSRemoteException,
CSExpiredSessionException,
CSException
Gets the extended attribute names that match the specified regular expression, along with sizes of their values.

Parameters:
regex - regular expression to match the extended attributes. Regular expression ".*" will get all the extended attribute names (and their value sizes) for the file.
Returns:
array of CSNameSizePair for the matching extended attributes for the file

Hi,
I was searching the threads to retrieve value one EA set on dcrs. My inputs may not be related with this thread (which speak about reading all key,value pair of EAs). Even though I am posting below simple code snippet (to retrieve EA if key is going to remain constant in dct design) so that it might help pople like me.


String workarea=task.getArea().getVPath().getPathNoServer ().toString();
String dcrFilePath = (new StringBuilder()).append(workarea).append("/templatedata/geam-content/bio/data/").append(fileNameWithoutExtension).toString();
  CSVPath csvpath = new CSVPath(dcrFilePath);
  CSFile bioDcrCSFile = client.getFile(csvpath);
  CSSimpleFile bioDcrCSSimpleFile = (CSSimpleFile) bioDcrCSFile;
  String bioImgAtrrib = bioDcrCSSimpleFile.getExtendedAttribute("geam/metadata/photo").getValue();
  LOG.debug((new StringBuilder()).append("value of bio photo attribute ").append(bioImgAtrrib).toString());

Regards,
