QUESTION
I'm just starting to explore openliberty, so maybe there is something trivial I did not see.
The project is generated by https://openliberty.io/start/ with java version 17, jakarta ee 9.1 and microprofile 5.0 options.
environment:
- open liberty: 22.0.0.3
- jdk: OpenJDK Runtime Environment GraalVM CE 22.0.0.2 (build 17.0.2+8-jvmci-22.0-b05)
- maven: 3.8.5
ANSWER
Answered 2022-Apr-03 at 08:26For the time being (see environment info in the question) mvn liberty:dev
throws an error if maven.compiler.source
or maven.compiler.target
is used together with maven.compiler.release
even if the version numbers are aligned. So you either have to use
maven.compiler.source
and/ormaven.compiler.target
withoutmaven.compiler.release
ormaven.compiler.release
withoutmaven.compiler.source
and/ormaven.compiler.target
If you are working in a maven-multi-module project where the above properties were defined in parent modules you can workaround this issue by overriding the properties appropriately.
QUESTION
Usings the OpenLiberty sessionCache-1.0 feature with HazelCast enables you to easily persist and share session data in a HazelCast in-memory cluster as explained here: https://openliberty.io/guides/sessions.html.
However in this setup session data is stored internally in the maps named: com.ibm.ws.session.attr.[app-context-root] & com.ibm.ws.session.meta.[app-context-root] as indicated here (I don't see the OpenLiberty docs clearly specifying this though)
This prevents different apps (with different context-roots) to share session data since they are writing and reading session data from different named maps.
Is there a way to overwrite this name to enable apps with different context-roots to read write from the same map to share session data?
I was going over the httpSession- and httpSessionCache-properties in the OpenLiberty docs but could not find any attribute supporting such a thing.
...ANSWER
Answered 2021-Nov-19 at 15:06To share session between different Web apps within the same EAR, you can use shared-session-context in ibm-application-ext.xml to enable all Web apps use the same session context-root.

QUESTION
I try to implement a microservice client to receive multipart form-data. I'm using Eclipse Microprofile and Openliberty. Therefore, I used the example sketched on https://openliberty.io/docs/21.0.0.6/send-receive-multipart-jaxrs.html.
In the example I see a method having a parameter with type IAttachment. However, I don't have a library providing this interface in my workspace (Eclipse).
How do I need to configure my pom.xml to get this interface?
Which library should provide this interface?
ANSWER
Answered 2021-Aug-03 at 16:13The IAttachment
class is a WebSphere/Liberty-specific interface, so you'd need to add this dependency to your pom.xml:
QUESTION
Deploying OpenLibertyApplication rewrites the /config/server.xml specified in the container image
What did you do?- Deployed OpenLibertyApplication with initial configuration in src/main/liberty/config/server.xml:
ANSWER
Answered 2021-Jul-05 at 10:39The problem in this case was cached image with the latest
tag. If the application is created without specifying policy, it is set to pullPolicy: IfNotPresent
to optimize creating container. Since the OP first created image with incorrect settings, and then overwrite image with the same tag, OCP used cached version.
To ensure that you are using correct image either:
- change the tag name
- set
pullPolicy: Always
in your application definition
QUESTION
How can I iteratively run my unit/integration tests in "dev mode" of the liberty-maven-plugin and easily turn on and off the launching of the debugger into the JVM running the tests themselves?
BACKGROUNDWhile the liberty-maven-plugin by default starts the Open Liberty server in debug mode, sometimes you need to debug into the source of the unit/integration tests themselves. The liberty-maven-plugin dev mode launches the server and will (by default) run my tests each time I hit .
I can leverage standard documented approaches, which by default will launch a forked JVM waiting for a debugger on port 5005, e.g.:
...ANSWER
Answered 2021-Feb-10 at 19:16An easy way to "toggle" the debug mode for the tests is to use Maven project properties and dynamically comment/uncomment out the standard test debug properties, e.g. maven.failsafe.debug.
E.g this will launch ITs in a forked JVM, suspended and waiting for the debugger on port 5005:
QUESTION
I'm doing practise openliberty.io multimodules with following that guide ( URL ). It's works fine as defaults.
But I want to use skinnyWars structure, i got errors when i run liberty:run or liberty:dev goals and couldn't resolve it.
Process steps;
I set skinnyWars parameter to true;
...ANSWER
Answered 2020-Dec-07 at 20:50For liberty:run, an issue has been opened here: https://github.com/OpenLiberty/ci.maven/issues/1054
liberty:dev currently does not support multi module projects. That will be addressed by https://github.com/OpenLiberty/ci.maven/issues/697
QUESTION
Trying to deploy a liberty application to OCP and merge the liberty logging with the application logging per example: https://openliberty.io/blog/2020/05/19/log4j-openshift-container-platform.html
Our application uses LOG4J2 to configure and run the logging. This worked sofar with following dependencies.
...ANSWER
Answered 2020-Nov-05 at 14:53Unfortunately, I believe if you use the log4j-to-slf4j adapter, log4j2.xml configuration will be ignored. Any logging configurations must be changed on your server side in your server.xml. In the case of filtering your logs based on log level, you can use the consoleLogLevel attribute. In your bootstrap.properties file:
QUESTION
I configured the Open Liberty server inside Eclipse 2020-03 using the Eclipse Developer Tools from https://openliberty.io/downloads/#eclipse_developer_tools.
I can add my .war project and start the server without problem, but publishing on the running server results in an Error:
Also at startup there is an error in the server console:
...ANSWER
Answered 2020-Apr-14 at 12:05The localConnector-1.0 feature is required by the tools in order to connect to the server. If it is not there you will get that error message about the JMX connection failure and the tools will keep trying to add it back to the server.xml. Are you using a minimized server with only a specific subset of features? You could install the localConnector-1.0 feature using the installUtility that comes with Liberty. It is found in the bin directory:
