Working on Jar and Zip code using the NetBeans IDE+
−
+
−
This note is specific to working on jar and zip; much more information about+
−
working with this project and others is in ../README.+
−
+
−
This project allows developers to work on the Jar and Zip in java.util.jar and+
−
java.util.zip, as well as the jar tool itself in sun.tools.jar.  The NetBeans+
−
project supports editing, building, testing, and debugging of this code.  This+
−
is a make-based project, and involves compilation of native code.  Some of+
−
this native code is provided by the JDK community, but the base zip library is+
−
from http://www.zlib.net.+
−
+
−
Please note: The most recent zlib is version 1.2.3.  We are providing zlib+
−
version 1.1.3, modified to include security fixes that have been added since+
−
that release.+
−
+
−
Source code layout+
−
+
−
The jar tool depends on the jar library, which in turn depends on the zip+
−
library.  This in turn depends on some native code, which in turn depends on+
−
the zlib library:+
−
+
−
sun.tools.jar depends on+
−
  java.util.jar, which depends on+
−
    java.util.zip, which depends on+
−
      src/share/native/java/util/zip, which depends on+
−
        src/share/native/java/util/zip/zlib-1.1.3.+
−
+
−
The project is set up to invoke make on the zip code first.  This make target+
−
compile the native zip code, as well as the Java sources in java.util.zip.+
−
Subsequent invocations of make build java.util.jar, and then sun.tools.jar.+
−
+
−
Insofar as NetBeans use is concerned with Java code, most things you are used+
−
to.  You can build the project.  There are several regression tests included,+
−
run either as a group via Test Project or individually via Run File.+
−
Debugging is also supported, try Debug File.  Since the jar tool needs command+
−
line parameters in order to do anything interesting, it is not hooked up to+
−
Run Project in NetBeans.+
