= Camel in a `.war` | ||
|
||
> Please raise any issues found with this example in this repo: | ||
> https://github.com/wildfly-swarm/wildfly-swarm-examples/issues | ||
> | ||
> Issues related to *WildFly Swarm* core should be raised in our JIRA: | ||
> https://issues.jboss.org/browse/SWARM | ||
|
||
This example demonstrates how to use the default Camel `.war` demo | ||
with WildFly Swarm. | ||
|
||
== Project `pomx.xml` | ||
|
||
The project is a normal maven project with `war` packaging. | ||
|
||
[source,xml] | ||
---- | ||
<packaging>war</packaging> | ||
---- | ||
|
||
The project adds a `<plugin>` to configure `wildfly-swarm-plugin` to | ||
create the runnable `.jar`. | ||
|
||
[source,xml] | ||
---- | ||
<plugin> | ||
<groupId>org.wildfly.swarm</groupId> | ||
<artifactId>wildfly-swarm-plugin</artifactId> | ||
.... | ||
</plugin> | ||
---- | ||
|
||
As with the other examples, this one inherits a few standard executions | ||
from the parent `pom.xml`, particularly the `package` execution. | ||
|
||
To define the needed parts of WildFly Swarm, a few dependencies are added | ||
to support the `.war` deployment: | ||
|
||
[source,xml] | ||
---- | ||
<dependency> | ||
<groupId>org.wildfly.swarm</groupId> | ||
<artifactId>wildfly-swarm-undertow</artifactId> | ||
</dependency> | ||
---- | ||
|
||
== Run | ||
|
||
You can run it many ways: | ||
|
||
* mvn package && java -jar ./target/example-camel-war-swarm.jar | ||
* mvn wildfly-swarm:run | ||
* In your IDE run the `org.wildfly.swarm.Swarm` class | ||
|
||
== Use | ||
