Error converting InputStream to a BinaryValue

[m.jawwad]

Hi,

      I was working with ModeShape and finally converted my application (working on JR previously) to ModeShape, It worked fine on my developer machine (Windows). Then I deployed it on a test machine which was using linux. The repository was initialized successfully, but When I started some document uploading, I encountered the following exception:

               The folders are created but when it comes to converting input stream to binary, the above exception is thrown on any type of file. Is  there any special configurations I might be missing? or is this a problem with the system/platform?

Thanks in advance.

When uploading binary values in the FS binary store, before creating the actual file in the store, ModeShape attempts to read the stream and store in a temporary location, via Java's java.io.File.createTempFile.

The standard JRE behavior of the above method is to create a file in the directory referred by the "java.io.tmpdir" system property.

You need to check what the value of System.getProperty("java.io.tmpdir") is on your Unix box, make sure that that folder exists and the user under which the ModeShape code is executed has read/write privileges in that folder.

Thanks. That was the problem. Modeshape was not able to create the temp folder.
