compressionfme
I have downloaded 21 zipped folders using the HttpFetcher transformer and I cannot figure out how to get FME to unzip these files.
I've seen some posts about using either the TclCaller or PythonCaller transformer, but I've tried that without luck.
Does anyone out there know how to unzip directories, using FME?
Check out the Learning page on the Safe Software web site.
There are tutorials for both the basic Desktop product (I recommend doing that first) and then one for Spatial Databases. Those two should get you going in no time.
We (I work at Safe) don't put prices out there because there are so many licensing options (and resellers) and we want to make sure users get the product they need. There are also fixed and floating licenses which complicates matters. To write to SQL Server you'll need a 'database' edition (there are several with different names but basically the same functionality).
I suspect the price will be a little higher than the numbers quoted here which I think would be for the lower-level Professional Edition. But I don't work for the sales team so I can't really be sure. But there's no secret to them; just contact our sales team or your local reseller and they will be happy to give you a price.

Same Oracle Spatial Connection - Same TABLE - but using two TESTERs to define FeatureType
and then write the to visualiser (or Shapefiles)

This one's a little trickier than it probably should be.
Your options are as follows.
Reader/FeatureReader
If the zip files you want to read are fixed, you can you/should use a Reader/Feature Reader. These can decrypt the zip file automatically.

HttpFetcher
If you must use a HttpFetcher, you will need to write the contents of the response to your disk before unzipping it. You do this with an AttributeFileWriter. Then there are various options for unzipping:
exec unzip -oq @Value(_ZipFileName)) followed by a FeatureReader (suboptimal)For more information on the process see: http://fmepedia.safe.com/articles/How_To/Read-Zip-File-from-URL-as-Source-Data-for-Workspace ; However, Note that this is dated 2011, so doesn't account for the fact that FME as of 2013 supports native ZIP file reading with Readers.
