Java 11 support: Naked Objects pattern

[iluwatar]

In issue https://github.com/iluwatar/java-design-patterns/issues/976 JDK11 build was taken to use but one problem related to Naked Objects pattern remains. Issue description from @lbroman:

In my PR #980 I have left language source and target at 8 for the naked-objects/dom module. This is because java 11 bytecode breaks the datanucleus enhancer, even if they claim that 5.2 should support java 11 bytecode. I have tried fiddling with the datanucleus dependency versions because the module uses datanucleus core 5 and apis from 4 so I thought that might be the problem. However, bumping up the versions breaks other stuff as they seem to have moved around some classes between 4 and 5.

hi, please can u help me to run naked objects pattern project.. please.. i am new to maven. i tried to build naked objects project. Seperate jars are getting created for dom,fixture,integtests and webapp folder and also simpleapp.war inside webapps/target. How do i run this war file? I installed tomcat also..

[iluwatar]

@tejashreeegithub there are many ways but probably easiest is to use the executable jar. First build it with mvn clean package and then in the webapp/target you can run java -jar naked-objects-webapp-1.22.0-SNAPSHOT-jetty-console.jar

[iluwatar]

One way to resolve this issue could be to try to update the whole pattern. The instructions can be found on the Apache Isis website https://isis.apache.org/guides/ugfun/ugfun.html#_ugfun_getting-started_simpleapp-archetype.

@iluwatar The above link is broken could you please update it with the relevant URL.

[iluwatar]

The links have changed, but the website still contains all the relevant information. See https://isis.apache.org/ The idea is to use the simpleapp archetype and recreate the naked objects example with that.

ok.

tq
