It can't read from two such streams simultaneously, however it can read from stdin. You tell it to do that by specifying a hyphen (-) as of one of the filenames. This is described in the diff documentation. Your program can write to its stdin by writing to diffProc.getOutputStream(). FromJava you can write to named pipes using regular file operations, so presumably you could create a named pipe and pass its name to diff, then then write to it from your Java program. You will need to use an external helper to create the named pipe however (mknod or mkfifo). If this seems complicated, consider writing the data to two temporary files and passing their names to diff. Alternately, there may be a Java version of diff that you can invoke directly.

Do you know how to handle these streams? Your code works when I run it, however there may be a race condition when you create the fifos in a separate thread. Do you know that they exist before diff attempts to open them? Create the fifos in the main thread; write to them in the writer threads. Also, in your example, you wait for diff to finish before getting the output stream. To avoid deadlocking, you need to read from diffs output while it runs. If diff's output stream fills and there is nobody reading from it, diff is prevented from continuing (and you block waiting for it). /gordon -- [ do not email me copies of your followups ] g o r d o n + n e w s @ b a l d e r 1 3 . s e ============================================================================== TOPIC: Good Tutorials? http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/e1bfe9d64672b57e ============================================================================== == 1 of 1 == Date: Wed, Dec 8 2004 4:18 pm From: "JS" Where can I find good Java tutorials?

IMO, it would cause > more confusion than it saves. "The whole hog or none" seems to apply here. Java's "static" context is an irregularitly - and an unnecessary one. If - for whatever arcane security reason, class members can't be associated directly with the class objects, they ought at least to be associated with *some* object. Otherwise you wind up with the Java situation - where there's a whole bunch of extra material in the JLS to deal specifically with static entities, how they are (or aren't) inherited - what happens when a member variable overrides a static one in an inherited class - and so on - all pointless irregularity that makes the langage harder to learn, and makes parsers and compilers more difficult to write. -- __________ |im |yler http://timtyler.org/ [EMAIL PROTECTED] Remove lock to reply. == 2 of 2 == Date: Wed, Dec 8 2004 8:00 am From: Tim Tyler Darryl L.

Actually there would be three ways: "ClassName.var" "var" ...or... "static.var". They don't say quite the same thing as each other - though they would all refer to the same static variable. -- __________ |im |yler http://timtyler.org/ [EMAIL PROTECTED] Remove lock to reply. ============================================================================== TOPIC: This group is new? http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/9a9e7de1fff77726 ============================================================================== == 1 of 1 == Date: Wed, Dec 8 2004 8:05 am From: Chris Smith Diphay Z <[EMAIL PROTECTED]> wrote: > lots of person > The comp.lang.java.programmer programmer has been in existence since July 11, 1996.

Eclipse 3.0 split the task tags (todo) and compiler errors into separate panes ("Tasks" and "Problems"). And indeed todos must now be enabled in Window->Preferences ->Java->Task Tags.
