    Resolution: Won't Fix


Hi Robert I just saw in the mailing list* that you can set <property name="java.io.tmpdir" value="" /> in the appengine-web.xml . That fixes this issue without having to patch Tapestry.

> I'm trying to deploy a tapestry project to GAE. Everything seems to work fine except for tapestry-upload. In fact the application will crash on startup if the tapestry-upload library is on the classpath, even when I contribute my own GAE compatible FileItemFactory.
> After a little bit of digging I found the offending line in UploadModule:
> configuration.add(UploadSymbols.REPOSITORY_LOCATION, System.getProperty("java.io.tmpdir"));
> This line will throw a NPE when System.getProperty("java.io.tmpdir") returns NULL. I couldn't find any quick workarounds without having to touch the UploadModule code, that's why I'm filing this issue.
> My naïve attempt to fix this is to use:
> String tmpdir = System.getProperty("java.io.tmpdir");
> if (tmpdir != null) configuration.add(UploadSymbols.REPOSITORY_LOCATION, tmpdir);
> But I don't know If I should consider other scenarios.
