Deploying 26.03

在 ChatGPT 中打开

The webforJ Maven plugin deploys an app to BBjShip with three goals:

Goal	Runs	What it does
bbj-package	with the package phase	Writes the deployment archive target/bbj/<publish name>.zip
bbj-deploy	with the install phase	Writes the archive and deploys it to BBjShip
bbj-undeploy	by hand	Removes the app from BBjServices

The phases apply when the plugin is declared with <extensions>true</extensions> and a <bbj> block, see Configuring a project.

Deploy

mvn install

Without the extension, run mvn package webforj:bbj-deploy. The goal prints the address of the app when the deploy completes:

[INFO] BBj deployment of inventory completed at http://localhost:8888/webapp/inventory

When a deploy fails, the previous version keeps running.

Replaces the app

A deploy replaces the app that already has the same publish name. The previous deployment folder is removed and the running sessions of that app end. Keep the archive of the previous version if you may need to go back.

Troubleshooting lists the messages of a failed deploy and what to do about each.

Package without deploying

bbj-package writes the same archive without a deployment URL or credentials. A CI job can attach target/bbj/<publish name>.zip to the build, and a BBj administrator deploys it on the BBj machine with bbjship apps deploy.

Undeploy

mvn webforj:bbj-undeploy

The app stops and is removed from Enterprise Manager, together with its files.

Can't be undone

bbj-undeploy ends the running sessions of the app and deletes its deployment folder. This can't be undone. Keep the archive from target/bbj/<publish name>.zip if you may deploy the app again.

Publish names

The publish name defaults to the final name of the build and appears in the app address. It starts with a letter or digit, holds only letters, digits, _, . and -, and doesn't end with a dot. Reserved names, such as the BBjServices paths webapp and files or the Windows device name con, are refused before the archive is written.

Each entry class belongs to one deployed app. Deploying it under a second name fails with:

BBj deployment failed with HTTP 409. Entry class com.example.Application is already published as inventory. Undeploy inventory first

Deploying from another machine

A deploy from another machine, such as a CI server, uses an authorization token over HTTPS:

1. On the BBj machine, enable the endpoint with an SSL port.
2. In Enterprise Manager, create a token under Security, Authentication Tokens. Renew and revoke it there as well.
3. Pass the token to the build:

mvn package webforj:bbj-deploy \
  -Dwebforj.bbj.deployment.url=https://bbj.example.com:8443/webforj-bbjship \
  -Dwebforj.bbj.admin.token="$BBJ_ADMIN_TOKEN"

The certificate of the BBjServices web server must match the host name of the URL, or be in the Java truststore of the build. Java doesn't trust the BBj default certificate, which is self signed. An http:// URL to another machine sends the credentials readable over the network, and the goals print a warning for it.

App settings

BBjShip reads the webforj.conf of the app on every deploy and applies these properties to the app in Enterprise Manager. A redeploy picks up a changed value. A property that isn't set keeps the default of BBjServices.

webforj.conf

webforj.assetsSource = packaged
webforj.disallowConsole = true
webforj.programArguments = ["mode=demo", "region eu"]

Property	Default	Description
webforj.assetsSource	Unset	packaged serves the ws:// static files and the icons:// icons from the app, at /webforj/<publish name>/. Without it, an app that uses icons:// fails to start.
webforj.showClientConfirmationDialog	false	Whether the browser asks for confirmation before the page closes.
webforj.disallowConsole	true	Whether the console is disallowed in the app.
webforj.secure	BBjServices default	Whether the app runs over a secure connection.
webforj.configFile	BBjServices default	Path of the BBj configuration file the app runs with, as BBjServices reads it on the BBj machine. The path is passed on as written, so it may name a file only the server has.
webforj.programArguments	None	Program arguments of the app, as a list of strings or as one string.

An invalid webforj.conf fails the deploy with HTTP 400 and the reason.

Settings

The settings live in the <bbj> block of the webforj-maven-plugin configuration, as shown in Build plugin. Each property overrides its element on the command line.

Maven element	Maven property	Default	Description
<home>	webforj.bbj.home	Detected	BBj installation folder, used by bbj-setup and watch.
<publishName>	webforj.bbj.publishName	Final name of the build	Name the app is published under, see Publish names.
<deployment><url>	webforj.bbj.deployment.url	None, required	Address of BBjShip, http://<host>:<HTTP port>/webforj-bbjship or https://<host>:<SSL port>/webforj-bbjship.
<admin><username>	webforj.bbj.admin.username	admin when user name and password are both absent	BBj administrator user name.
<admin><password>	webforj.bbj.admin.password	admin123 when user name and password are both absent	BBj administrator password.
<admin><token>	webforj.bbj.admin.token	Empty	Authorization token for bbj-deploy and bbj-undeploy. Takes precedence over the user name and password.
<properties>	webforj.bbj.properties	<home>/cfg/BBj.properties	BBjServices properties file a development run writes the hotswap settings into.
<development><classFolder>	—	Build output directory	Class folder of a development run as BBjServices reads it.
—	webforj.bbj.force	false	Lets bbj-setup replace an installed BBjShip of another version. Property only.

A user name without a password, or a password without a user name, stops the goal.
