build.CompilingClassLoader
| CompilingClassLoader | | public class CompilingClassLoader extends LoadletClassLoader (Code) | | A ClassLoader that will recompile the *.java file corresponding to
an out of date or missing *.class file. It also runs rmic to
generate *_Stub.class and *_Skel.class files used by RMI.
A single CompilingClassLoader uses a sequence of pairs of
directories:
- classBase - where to look for *.class files.
- srcBase - where to look for *.java files.
The -Dbootstrap.path System property can contain a sequence of
classBase,srcBase pairs separated by ",". The default is
"-Dbootstrap.path=.,.". For each class,src pair, a new
CompilingClassLoader is constructed and chained to previous ones.
Sample Usage:
Supose we have a Java application, app, with the following files and
classes:
- app.Main - Main class of the application.
- app/classlib/ - class file directory.
- app/src/ - java file directory.
- app/build/ - where this file is
- jdk/lib/tools.jar - JDK *.jar file containing javac.
The to compile and run the application, do:
javac -classpath app;jdk/lib/tools.jar -d app
app/build/CompilingClassLoader.java
java -Dbootstrap.path=app/classlib,app/src
-classpath app;jdk/lib/tools.jar
CompilingClassLoader app.Main
The -classpath must provide access to CompilingClassLoader and
tools.jar. It should not contain any directories for classes that
you want recompiled. Specify them in -Dbootstrap.path instead.
When getting a class by name, use
CompilingClassLoader.forName() rather than Class.forName(). This
will recompile such classes as necessary.
