Definition

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

low, medium 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 3 goals or Ant tags, see chapters with Maven 3 plugin and Ant tasks' documentation.

string

N/A

 
name1:pwd1:role11,...,role1N|name2:pwd2:role21,...,role2N|...

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.maven3</groupId>
      <artifactId>cargo-maven3-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 3 goals) can also be overriden using Java properties.

For example, with the Maven 3 plugin:

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