We are using Vert.X library to develop REST service layer to receive messages from many sources. Part of the requirements is to run REST verticle(s) in High availability (HA) mode. We are following vert.x core manual for implementation of VertX cluster to run in distributed cluster (3 nodes to start with).
Based on the documentation we did the following
Included hazelcast library in dependencies
io.vertx
vertx-hazelcast
3.3.0
Created a fat jar with the following manifest entries and added resources folder in classpath which has required configurations to load. We took hazelcast-default.xml from vertx-examples from github
log4j.properties
config.json
hazelcast-default.xml
io.vertx.core.Launcher
com.msg.verticles.RootVerticle
resources/
Created a script file to trigger the launcher
java -jar -Xmx2048m -Xms512m message-1.0-SNAPSHOT.jar -ha -D config=resources/config.json
Launcher fails to to pickup hazelcast-default.xml from resurce folder and stops with the following exception. Not sure what I am missing here.
$>java -jar -Xmx2048m -Xms512m message-1.0-SNAPSHOT.jar -ha -D config=resources/config.json

According to the documentation of Hazelcast cluster manager you need to specify your Hazelcast configuration in a file named cluster.xml in your classpath (either embedded in the root of your fatjar or in a directory that is in your classpath).
Solved the issue by configuring zookeeper as co-ordination service. Which worked like a champ!!

I have a java Spring Boot app which is being packaged into a "thin jar" using the spring boot maven thin jar plugin. I followed instructions from here https://www.baeldung.com/spring-boot-thin-jar and it's all working great. I can deploy new versions of my app in lightweight jars while the production server running the app maintains its own .m2 repository, updating if the new thin jar lists any new dependencies.
Recently I wanted to include my own external library. This is hosted in a gitlab-maven package repository and accessed via an access token. I set this up following instructions here: https://docs.gitlab.com/ee/user/packages/maven_repository/
I've written a settings.xml and saved to home/user/.m2/settings.xml which includes the access token.
After that any mvn ... command is pulling the library into the repository as expected. So far so good.
However when I create my thin jar and try to run with java -jar thin-jar.jar it fails to get the library. The error is as follows:
$ java -Dthin.trace=true -jar thin-jar.jar

I'm assuming this is because the repository is private and somewhere along the way the authentication is failing while trying to pull that library? Looking at the trace it appears to load the settings file properly, so where is it going wrong?

I can't run my project.
What already I did:
- clear&build
- tryed to change ports from 8080 to 9090
- closed connections in TCPView on localports
- closed Java Binary process in task menager and still not working.
When i running project i got this:
C:\Users\MyName\Desktop\Java Web Profile\MyProject\nbproject\build-impl.xml:1048: The module has not been deployed.
See the server log for details.
1047-1049 lines from build-impl.xml:
<target if="netbeans.home" name="-run-deploy-nb">
<nbdeploy clientUrlPart="${client.urlPart}" debugmode="false" forceRedeploy="${forceRedeploy}"/>
</target>
Any ideas? :)
I found this solution/cause on another site, didn't resolve the issue for me but hopefully it can help you:
Reasons: In mac OS Sierra ,the new update blocks the sites which uses system proxy settings, where localhost,127.0.0.1 all connections are blocked.
Solution:
Step 1: Go to system preference >Network>Select your wifi connection>Advanced>select proxies tab.
There check 3 options 1) Auto proxy Discovery 2)Automatic Proxy configuration 3) web proxy(http)
Step 2: Go to Netbeans>preferences>General> select use system proxy> reload> test connection
You may get connection successful.
If connection gets successful, Now Clean & build your Applications in netbeans and press run .
Hope it will work . In my case it works.

I have build the whole app using maven and tried to deploy admin.war it on a standalone tomcat7, during the server start-up, it is showing some error : but still the server starts up,
due to this , when i go to products->Inventory -> the Available Quantity field is missing. But the same field is available, when i am running through eclipse.

The inventory was added in version 3.1.3 make sure you are using this version or newer version.
It was added using
org.broadleafcommerce.common.extensibility.jpa.copy.DirectCopyClassTransformer
Which adds the field at run time, but this creates the dependency on "Spring Instruments", which needs to be added as javaagent
So you can edit your /path/to/tomcat/bin/setenv.sh and add following
JAVA_OPTS="-Djava.awt.headless=true -Xmx1024M -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled -XX:MaxPermSize=256M -Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n -javaagent:/path/to/spring-jar/spring-instrument-3.2.2.RELEASE.jar"
Adjust Xmx and other tomcat setting and replace /path/to/spring-jar/ with actual path.
.I'm using Newrelic for java agent.I install the newrelic.yml file using the command "java -jar newrelic.jar install" in my prompt. When running, it shows the message as INSTALL SUCCESSFUL and some other information. I also find the newrelic.yml setup in running the run.bat file.But i'm not able to see the newrelic API in my browser when running the port as "localhost:8080/newrelic" . I'm started my server in the port 8080.

Help me please..?
The New Relic Ruby agent has a Developer Mode that lives at the /newrelic path you're trying to reach, but the Java agent does not. Developer Mode would give you a detailed trace of each individual web request your app makes that's similar to what the normal New Relic product does with Transaction Traces.
To use New Relic and report performance data, it looks like you've got everything configured correctly. You should be able to log in to https://rpm.newrelic.com and see what your app is doing.
You mentioned "the newrelic API", but I'm not sure what you are looking for exactly. There is an API for the Java agent that lets you configure the agent. There's also a New Relic HTTP REST API that will let you retrieve data reported by your applications.
I'm embarrassed to have to ask this, but I can't for the life of me figure out what I'm doing wrong.
I've downloaded the appengine-java-sdk-1.4.2 via the eclipse 3.6 plugin as per the instructions on Installing the Java SDK page. I am running Mac OSX 10.5.8 with JRE version 1.5.0_26. I have made the dev_appserver.sh file executable (chmod u+x dev_appserver.sh) and when I attempt to start the app server with one of the demos via the command
bin/dev_appserver.sh demos/guestbook/war/
I get the following output, but the server does not start up:

I see the warning about upgrading the JRE, but I don't think this is the problem, as there are no exceptions reported. It just won't start up. I've tried creating a hello world app from within Eclipse using the plugin and running as Web server, but that also spits out the same text but does not start up the web server.
Any idea what I'm doing wrong and how to remedy the problem?
By changing the line in dev_appserver.sh to
/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Commands/java -ea -cp "$JAR_FILE" \
com.google.appengine.tools.KickStart \
com.google.appengine.tools.development.DevAppServerMain $*
instead of using the default java (which is set to 1.5.0_26 as I mentioned earlier) the web server starts up.
I had the same problem and simply tried running Eclipse as Administrator and then debugging worked fine.
