----------------------------------------
Hi Karel.
Thanks for taking a look.
JDK: openjdk version "11.0.7" 2020-04-14
OpenJDK Runtime Environment (build 11.0.7+10-post-Ubuntu-2ubuntu218.04)
OpenJDK 64-Bit Server VM (build 11.0.7+10-post-Ubuntu-2ubuntu218.04, mixed mode, sharing)
Kie Server: 7.29.0.Final
Container: jetty-distribution-9.4.22.v20191022
Configuration: [^start.ini]
Command line that I have been using to start Jetty:
{code}java -jar current-version/start.jar -Xdebug
-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=8000{code}
To build, you should just be able to do {code}./gradlew clean build{code}. This will
build the deployable artifact (although as a Jar -- I haven't setup a kjar plugin
yet). {code}./gradlew tasks{code} will give you a list of runnable tasks.
{code}./gradlew clean build{code} will generate the jar archive
[^KieIssueDemo-0.1.0-SNAPSHOT.jar] .
{code}./gradlew install{code} will install into your local archive.
Note that you do not need to install gradle in order to use gradle -- it's self
installing via an internal bootstrap mechanism.
Normally, I have just been running this from Eclipse as an application with no parameters.
The client normally invokes a CreateContainer command on the server -- although only on a
server with no containers currently deployed.
{code}com.j2eeguys.demo.DemoKieClient{code} is the main class. My apologies for not
setting up the Gradle build file to run as an application. If you need me to add that
capability, please let me know. It's fairly straight forward, I just didn't think
of it before. Note, when you first run the app, it will fail with "No Endpoints
found" after starting the kcontainer. You will need to wait for the kcontainer to
finish starting (takes 6-7 minutes, mostly for KiePMML-*-Rules to not find any files)
before trying again. At which point, it should work and generate the following post:
{code:xml}
14:04:19.354 [main] DEBUG org.kie.server.client.impl.AbstractKieServicesClientImpl - About
to send POST request to
'http://<server>:8080/kie-server-7.29.0.Final-webc/services/rest/server/containers/instances/Kie
Demo: kie-server' with payload '{
"lookup" : "default-stateless-ksession",
"commands" : [ {
"insert" : {
"object" : {"com.j2eeguys.demo.DemoData":{
"name" : "DemoData1",
"group" : "KieIssueDemo",
"target" : "Demos",
"details" : [ "Inventory Item 001" ],
"definition" : "Demo Rule 1"
}},
"out-identifier" : null,
"return-object" : true,
"entry-point" : "DEFAULT",
"disconnected" : false
}
}, {
"fire-all-rules" : {
"max" : -1,
"out-identifier" : null
}
} ]
}
{code}
The Jetty distribution is 30MB with required libraries loaded. Your WAR is 80MB. I can
load these files on this ticket if you would like. Or if you would prefer it, I can copy
this to a VM in a DMZ and set up remote access. I would only need your public key to
setup remote access.
