Start Language Server from Command Line

[bdresdner]

Hi, does anyone know if there is a way to start the Java Language Server from the command Line? I have a workspace in my container with a Java class, and I would have the language server up and running before the user opens the class in an editor from the UI. This is for a Cloud-based application.

I have tried using the command:
/opt/mycompany/jvm/jvm/bin/java --add-modules=ALL-SYSTEM --add-opens java.base/java.util=ALL-UNNAMED --add-opens java.base/java.lang=ALL-UNNAMED --add-opens java.base/sun.nio.fs=ALL-UNNAMED -Declipse.application=org.eclipse.jdt.ls.core.id1 -Dosgi.bundles.defaultStartLevel=4 -Declipse.product=org.eclipse.jdt.ls.core.product -Djava.import.generatesMetadataFilesAtProjectRoot=false -DDetectVMInstallationsJob.disabled=true -Dfile.encoding=utf8 -XX:+UseParallelGC -XX:GCTimeRatio=4 -XX:AdaptiveSizePolicyWeight=90 -Dsun.zip.disableMemoryMapping=true -Xmx2G -Xms100m -Xlog:disable -javaagent:/home/sag/node_modules/@jse/java-service-editor-app/plugins/redhat.java/extension/lombok/lombok-1.18.28.jar -jar /home/sag/node_modules/@jse/java-service-editor-app/plugins/redhat.java/extension/server/plugins/org.eclipse.equinox.launcher_1.6.500.v20230717-2134.jar -configuration /opt/softwareag/.theia/globalStorage/redhat.java/1.23.2023092204/config_ss_linux -data /opt/softwareag/.theia/workspace-storage/9c491c7c323deca0a9a4af50687fc724/redhat.java/ss_ws

but I get an error:
java.lang.IllegalStateException: Unable to acquire application service. Ensure that the org.eclipse.core.runtime bundle is resolved and started (see config.ini).

Thank you
