Definition

API to manipulate J2EE archives, including vendor-specific deployment descriptors

Explanation

This API is located in the org.codehaus.cargo.module package and is used internally by the Cargo Java API. You can also use it yourself if you need to manipulate (read/write) J2EE archive files.

It also supports merging two web.xml files into one.

See the Javadoc for more details on the API.

Example

File warFile = new File("/path/to/simple.war");
WarArchive war = new DefaultWarArchive(warFile);

// Verify existence of class inside the WAR
assertTrue(war.containsClass("test.Test"));

// Verify version of the Servlet specifications used in web.xml
WebXml webXml = war.getWebXml();
assertEquals(WebXmlVersion.V2_3, webXml.getVersion());

// Add a context-param element in web.xml
Element contextParamElement = 
  createContextParamElement(doc, "param", "value");
webXml.addContextParam(contextParamElement);
assertTrue(webXml.hasContextParam("param"));
