https://curl.haxx.se/docs/manpage.html

j'ai tapé ça: javac ClientJava.java
il m'affiche ces erreurs:

[yildiz-online]

-cp pour ajouter un jar au classpath

[emmyhad]

javac -classpath javax.servlet-api-3.0.1.jar;javax.ws.rs-api-2.1.jar;jaxb-api-2.2.7.jar;jboss-interceptors-api_1.1_spec-1.0.0.Beta1.jar;jersey-client.jar;jersey-common.jar;jersey-container-servlet.jar;jersey-container-servlet-core.jar;jersey-hk2.jar;jersey-media-jaxb.jar;jersey-media-json-binding.jar;jersey-media-sse.jar;jersey-server.jar;jsr250-api-1.0.jar;org.osgi.core-4.2.0.jar;osgi-resource-locator-1.0.1.jar;persistence-api-1.0.jar;validation-api-1.1.0.Final.jar;yasson-1.0.jar;aopalliance-repackaged-2.5.0-b42.jar;cdi-api-1.1.jar;el-api-2.2.jar;hk2-api-2.5.0-b42.jar;hk2-locator-2.5.0-b42.jar;hk2-utils-2.5.0-b42.jar;javassist-3.22.0-CR2.jar;javax.annotation-api-1.2.jar;javax.inject-1.jar;javax.inject-2.5.0-b42.jar;javax.json.bind-api-1.0.jar;javax.json-1.1.jar;javax.json-api-1.1.jar ..\..\..\src\clientUC\ClientJava.java
