after several days of work and research, I finally find the solution of my problem. The problem is caused by a version conflict between dependencies of ES hight level client api and those existing on glassfish modules ( Jackson-core is one of them). Because replacing jars of glassfish module directory is a risky practice, the solution that I applied is to shade the ES dependency and rename there packages using maven shade plugin. These are followed steps to implement the solution:
- Create the shaded dependency of ES:
- Create a java maven project;
- The Pom.xml of the project:
<modelVersion>4.0.0</modelVersion>
<groupId>com.trustiser</groupId>

- Run clean, build and maven package goal;
The jar will be created on "elastic shade project location" \target
Add the shaded dependency on maven local repository:
- Access to m2 repository from the cmd, the default location is C:\Users\"user".m2\repository , and execute the following command to istall the created dependency: mvn install:install-file -Dfile="location of the shaded elastic dependency".jar -DgroupId="shaded dependency groupe id" -DartifactId="shaded dependency acrifact id" -Dversion="version of the shaded dependency" -Dpackaging=jar
Add the shaded dependency of elasticsearch on the pom.xml of my maven java web application instead of using elasticsearch hight level rest api directly
- To avoid log4j error I add a log4j2.properties file on the resources directory of my java web app :
appender.console.type = Console
appender.console.name = console
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = [%d{ISO8601}][%-5p][%-25c] %marker%m%n
rootLogger.level = info
rootLogger.appenderRef.console.ref = console
