Jon,

thanks for your help, but the attachment is broken (see 3710927023.txt).
Maybe you better rename it to build.txt.

Ulf,

I have pushed changes into http://hg.openjdk.java.net/jdk7/tl/langtools 
(for JDK7)
and into http://hg.openjdk.java.net/jdk6/jdk6/langtools (for JDK6.)

With these fixes, I can build langtools on Windows using either the 
attached build.bat
(for Windows shell) for build.sh (for Cygwin.)   In both cases I can 
build with just JDK 6.

   The original attachment - build.bat - has been removed from this
   message, as it is a type of file which has recently been used
   to carry viruses and other malicious software.

   The following extensions are no longer supported as valid
   email attachments and will be removed since they are primarily
   used to carry viruses and other malicious software:

John,

thanks for your files.

(1)
Do you like to update make/build.properties? :
...
# boot.java.home = /opt/jdk/1.6.0
...
# target.java.home = /opt/jdk/1.7.0

(2)
Your script builds separate javac.jar etc.
Can you add script to build complete tools.jar?

-Ulf

Yes, they're only comments, but updating them makes sense.

That I can't do, not the way you probably would want.   tools.jar
contains more than the aggregate contents of the langtools repository.  
langtools just contains "the language tools", javac, javadoc, javah,
javap, and apt.

tools.jar is built as part of building the main jdk/ repository, so to
build tools.jar you need to bring over the jdk/ repository and build
that. For that, you'll need to have MKS or Cygwin installed and run
"make" in that repository.  This will generate a jdk image containing
tools.jar. There is no easy short cut. Sorry. For full details on
building jdk/ see the OpenJDK web pages.

We are looking at the possibility of adding an optional target to the
langtools/make/build.xml file that would allow you to create a patched
version of an existing tools.jar. Perhaps that would be sufficient to
your needs.

Sounds good.

Yesterday I found smart tutorial/sample from NetBeans weekly newsletter:
