Working on JDBC Using the NetBeans IDEThis JDBC NetBeans project allows a developer interested in making changesto and/or fixing bugs in the JDBC source to modify, build, run and testas well as generating the javadoc.README FIRST make/netbeans/README to get started with NetBeans IDE and OpenJDK, and working with the OpenJDK NetBeans projects.WORKING WITH JDBCJDBC doesn't contain native code. You don't need tohave all the Java SE sources to work on JDBC but just the following subset: make/netbeans/ src/share/classes/com/sun/rowset/ src/share/classes/java/sql/ src/share/classes/javax/sql/ test/TEST.ROOT test/java/sql/ test/javax/sql/The set of actions supported by this project are:* Build Project: - Compiles JDBC source files and puts the class files under build/${platform}-${arch}/classes. - Generates JDBC's jar file under dist/lib/jdbc.jar This new jar file could be used to patch an existing JDK installation by using -Xbootclasspath/p:$MYSRC/dist/lib/jdbc.jar* Generate Javadoc for Project - Generates the javadoc for the JDBC source files, - The javadoc is generated under build/${platform}-${arch}/javadoc/jdbc.* Test Project - Runs the JDBC jtreg unit tests located under test/java/sql or test/javax/sql. - The test results are written under build/${platform}-${arch}/jtreg/jdbc and the HTML test report can be found at build/${platform}-${arch}/jtreg/jdbc/JTreport/html/report.html* Clean Project - Cleans the files created by this projet under build and dist.IMPORTANT NOTE Please make sure to follow carefully the governance rules documented at http://openjdk.dev.java.net/
