3 | 3 | This demonstrates modules and custom jre creation in JAVA 9. |
| 4 | + |
| 5 | +#### create directory to hold modules |
| 6 | +```` |
| 7 | +$ mkdir -p output/mlib |
| 8 | +```` |
| 9 | + |
| 10 | +#### compile hello module and make hello.jar |
| 11 | +``` |
| 12 | +$ javac -p output/mlib -d output/classes `find com.hello -name *.java` |
| 13 | +$ jar -c -f output/mlib/hello.jar -C output/classes . |
| 14 | +$ /bin/rm -rf output/classes |
| 15 | + |
| 16 | +```` |
| 17 | + |
| 18 | +#### compile helloclient module using hello module and make helloclient.jar |
| 19 | +``` |
| 20 | +$ javac -p output/mlib -d output/classes `find com.hello.client -name *.java` |
| 21 | +$ jar -c -f output/mlib/helloclient.jar --main-class com.hello.client.HelloClient -C output/classes . |
| 22 | +$ /bin/rm -rf output/classes |
| 23 | +``` |
| 24 | + |
| 25 | + |
| 26 | +#### program execution |
| 27 | +``` |
| 28 | +$ java -p output/mlib -m com.hello.client/com.hello.client.HelloClient |
| 29 | +``` |
| 30 | + |
| 31 | + |
| 32 | +#### Create custom JRE |
| 33 | +``` |
| 34 | +$ /bin/rm -rf helloclientimage/ |
| 35 | +jlink --module-path /Library/Java/JavaVirtualMachines/jdk-9.0.4.jdk/Contents/Home/jmods:output/mlib --add-modules com.hello --add-modules com.hello.client --output helloclientimage --launcher=helloclient=com.hello.client |
| 36 | +``` |
| 37 | +#### list custom jre modules |
| 38 | +``` |
| 39 | +$ ./helloclientimage/bin/java --list-modules |
| 40 | +``` |
| 41 | + |
| 42 | +#### custom jre exection |
| 43 | +``` |
| 44 | +$ ./helloclientimage/bin/java -m com.hello.client |
| 45 | + |
| 46 | +``` |
