Properties to configure a container (request port, shutdown port, logging level, threads, etc)

Explanations

It is possible to set container configuration properties using the Cargo API. These properties are applied to a Configuration.

There are 2 kinds of properties:

  • General properties
  • Container-specific properties. See each container's page for a list of all the properties it supports.

Some general properties:

Property name

Java constant (for the Java API)

Description

Valid values

Default value

Examples

cargo.hostname
GeneralPropertySet.HOSTNAME

Host name on which the container listens to

string

localhost
myserver
cargo.jvmargs
GeneralPropertySet.JVMARGS

JVM args to be used when starting and stopping containers

string

N/A
-Xmx500m
cargo.start.jvmargs
GeneralPropertySet.START_JVMARGS

JVM args to be used only when starting containers

string
N/A
-Xdebug
-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8000
-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=10000 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false
cargo.logging
GeneralPropertySet.LOGGING

Level representing the quantity of information we wish to log

lowmedium or high

medium
high
cargo.protocol
GeneralPropertySet.PROTOCOL

Protocol on which the container is listening to

http or https

http
http
cargo.remote.password
RemotePropertySet.PASSWORD

Password to use to authenticate against a remote container (when deploying for example)

string

Depends on the container

manager
cargo.remote.username
RemotePropertySet.USERNAME

Username to use to authenticate against a remote container (when deploying for example)

string

Depends on the container

system
cargo.rmi.port
GeneralPropertySet.RMI_PORT

The port to use when communicating with this server, for example to start and stop it

integer

Depends on the container

1099
cargo.servlet.port
ServletPropertySet.PORT

Port on which the Servlet/JSP container listens to

integer

8080
8280
cargo.servlet.users
ServletPropertySet.USERS

Allow defining users, passwords and map to roles. Note that having no roles at all for a user is allowed.

Users can be also set using dedicated Maven 2 / Maven 3 or ANT tags, see chapters with Maven 2 / Maven 3 and ANT documentation.

string

N/A

Datasource and Resource configuration

In addition to the "simple" properties presented here, some container also support properties for setting up datasources. You can read more on: DataSource and Resource Support.

Java API

Example of starting Tomcat 5.x on port 8081:

Configuration configuration = 
    new Tomcat5xStandaloneLocalConfiguration("target/tomcat5x"));
configuration.setProperty(ServletPropertySet.PORT, "8081");
[...]

You can check if a configuration supports a given property by using Configuration.getCapability().supportsProperty(String propertyName).

For example if you want to check if the configuration supports setting the port property:

boolean isPropertySupported = configuration.getCapability().supportsProperty(ServletPropertySet.PORT);

Ant Task

Example of starting Tomcat 5.x on port 8081:

<cargo containerId="tomcat5x" home="c:/apps/jakarta-tomcat-5.0.29" action="start">
  <configuration>
    <property name="cargo.servlet.port" value="8081"/>
  </configuration>
</cargo>

Maven Plugin

Example of starting Tomcat 5.x on port 8081:

<build>
  <plugins>
    <plugin>
      <groupId>org.codehaus.cargo.maven2</groupId>
      <artifactId>cargo-maven2-plugin</artifactId>
      <configuration>
        <container>
          <containerId>tomcat5x</containerId>
          [...]
        </container>
        <configuration>
          <properties>
            <cargo.servlet.port>8081</cargo.servlet.port>
          </properties>
        </configuration>
        [...]
      </configuration>
    </plugin>
  </plugins>
</build>

Using Java properties

All configuration properties (be it with the Java API, ANT tasks or Maven 2 / Maven 3 goals) can also be overriden using Java properties.

For example, with the Maven 2 / Maven 3 plugin:

mvn -Dcargo.servlet.port=8082 cargo:start
