Re: Naming of MTOM cached attachment files
Hi
I am using the cache feature of Axis2 1.1 for very large MTOM attachments
in a client component. Currently the files are being saved into the
defined temporary directory with a naming format similar to
"Axis28105.att, Axis28106.att, etc. This naming convention makes it very
difficult to identify which file was placed in the temp directory by which
user, so that the file can be retrieved and the temp directory cleaned up.
I am wondering how/where these names are constructed?
Is there any method to control the naming of the cached file, or to obtain
the name that will be used during the processing of the MTOM response?
Thanks,
Brian Bacsu

Brain,
Proper method is to use the functionality provided by DataHandler and
DataSource. DataHandler will not read the attachment in to the memory In the
case of a large attachment when it is cached in the temp dir. I In that
scenerio DataHandler will run off on file data source object which will in
turn refer to the physical temp file...

Thilina:
Thanks for the information. I will try that. The reason for using the
cache was to avoid placing very large files in memory, but if the cache is
for Axis2 internal use, what is the proper method to access/utilize these
files, once they have been obtained from the response, and stored in the
temp directory.
Thanks,

Re: Naming of MTOM cached attachment files
Hi,
Actually the temp directory is meant for Axis2 internal use. Also
only the attachments which are larger than the file size threshold
will get stored there...
But u can manipulate those files in the following way by adding some
code to the business logic.. (Make sure to make the file size
threshold 0)..
DataHandler dataHandler = (DataHandler)omText.getDataHandler();
// You can check the data source type for added safety
FileDataSource fileDataSource =
(FileDataSource)dataHandler.getDataSource();
File file = fileDataSource.getFile();
//Rename to your desired file name
file.renameTo(new File("MyFile.bin"));
Thanks,
Thilina
