#1 Updated by Ovidiu Maxiniuc over 8 years ago

  • Subject changed from Windowd to Windows OS support for P2J

This task is dedicated to track encountered issues that prevent P2J to run on Windows OS, other than those related to SQL Server. Normally, Java is not OS dependent, so there shouldn't be such issue except when it comes to native or file system.

At this moment, there are two known issues that need to be addressed:
  • some IOException thrown is some very particular case (I accidentally discovered this when using a cfg file not suited to my system so the E: disk was an empty CD drive).
  • the (newly introduced and with higher priority, I guess): native console initialization. The work on this issue is documented in task #2583.

  • Start date deleted (11/20/2015)
  • Subject changed from Windows OS support for P2J to IOException in Windows
  • Assignee set to Eugenie Lyzenko

Ovidiu: please post details of the IOException and how to recreate the problem.

The native console init will be worked separately in #2583.

The exception is thrown in com\goldencode\p2j\util\Utils.java. Here is an example of a complete exception stack:

The exact parameter for "f:/l/trng/procode/common", taken from database, table module probably. Important is that f: is my optical drive and it was empty at that time. If the drive would have been any other (I tried with A: or q:), the method would have returned the canonical path without throwing an exception. There are a number of other path that can come from server.ini or even hardcoded.

The important thing here is that if the input path for canonicalizePath is an otherwise invalid (read: inexistent) path the File.getCanonicalPath will return the best attempt to canonicalize it. If the path is really malformed, a java.io.IOException("Invalid argument") will be thrown.
