java.io.tempdir is a system property which presumably means it can be set on the Java command line using -Djava.io.tempdir="foo"
This is different then anything getenv() would return since those would be environment variables. Some of which are reflected as differently named system properties. For example, I think java.io.tempdir defaults to the TEMP environment variable under Windows and perhaps TMP under Unix or something like that. I'd have to drill into javadocs to be sure.

I don't know if this is helpful or not, Martin, but if you attempt System.getenv("java.io.tempdir") [which is deprecated], you get as part of the error message
"getenv no longer supported, use properties and -D instead: java.io.tempdir". Is that helpful? Does the -D there mean as in -Djava.io.tempdir?

formal syntax for the JSPC command

Where option

The -d output-dir specification is the directory specified by the
java.io.tempdir system property
I see that there are 2 ways to specify java.io.tempdir System Property
Anyone else
The directory specified by the java.io.tempdirsystem property The directory
specified by the java.io.tempdirsystem property The directory specified by
the java.io.tempdirsystem property The directory specified by the

Martin,
Perhaps I should add, Martin, that if I set the environment variables for java.io.tempdir and -Djava.io.tempdir in the application but not in Tomcat startup, I don't have the problem. I am a bit confused about whether to use java.io.tempdir or -Djava.io.tempdir. Can you explain a bit about that?

createTempFile employs 3 steps algorithm to locate/create "tempDir"
1) Attempt to retrieve the value of "javax.servlet.context.tempdir" from
the
ServletContext
2) If that's not found, attempt to retrieve the value of the
init-parameter
"tempDir"
3) If that's not found, default to the system-wide temp directory
specified
by the system property "java.io.tempdir" A)what is the value of "javax.servlet.context.tempdir" from the ServletContext? B)what is the value of the init-parameter "tempDir"?

I hope this is Tomcat related. If not, please accept my apologies, and
give me direction. I have removed from my Tomcat 5 (Struts 1.2 using a
custom taglib) service the java.io.tempdir setting because when I use
the following code:
File file = new File(Classpath.WEB_INF + "resource" + File.separator + "content_type" + File.separator + "ttf" + File.separator + physicalName); FileInputStream fontStream = new FileInputStream(file); Font font = Font.createFont(Font.TRUETYPE_FONT,fontStream); font = font.deriveFont(attributes); fontStream.close();
I get temp files of around 50 - 150 kilobytes each written to the temp directory. I requested assistance on Tomcat User without an answer.
Anyway, I assume that there may be a concurrency issue of somekind. Is
that right? Anyone with any assistance out there?
