I'm using JUnit test cases to exercise my web service using embedded Tomcat. Under Tomcat 6 everything was working fine, but when I switched my project to Tomcat 7 I'm coming unstuck.
The test code to setup the embedded Tomcat server is as follows:
Embedded container = new Embedded();
container.setCatalinaHome("C:\\Program Files\\Apache Software Foundation\\Tomcat 7.0.11");
container.setRealm(new MemoryRealm());
container.setName("Catalina");
Engine engine = container.createEngine();
container.addEngine(engine);
Host host = container.createHost("localhost", "/DecoderServiceTest");
Context rootContext = container.createContext("/DecoderServiceTest", System.getProperty("user.dir") + "/build/web");
host.addChild(rootContext);
engine.setName("Catalina");
engine.addChild(host);
engine.setDefaultHost("localhost");
container.addEngine(engine);
Connector connector = container.createConnector(InetAddress.getLocalHost(), 4321, false);
container.addConnector(connector);
container.start();
As the embedded API has changed between versions 6 and 7, I've changed my own code to the following:
Tomcat tomcat = new Tomcat();
tomcat.setBaseDir("C:\\Program Files\\Apache Software Foundation\\Tomcat 7.0.11");
tomcat.setPort(1234);
tomcat.addWebApp("/DecoderServiceTest", System.getProperty("user.dir")+"/build/web");
tomcat.setHostname("localhost");
tomcat.start();
The actual web service starts up fine when I execute the JUnit test (I can use my web browser and see the WSDL being served up).
However, in the constructor of my web service I intialise some variables based on the values in the web.xml file (which is located in System.getProperty("user.dir")+"/build/web/WEB-INF/web.xml"), as follows:
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");
int thumbnailSize = (Integer) envCtx.lookup("thumbnail-pixel-size");
Where my web.xml file contains the following entry:
<env-entry>
<env-entry-name>thumbnail-pixel-size</env-entry-name>
<env-entry-type>java.lang.Integer</env-entry-type>
<env-entry-value>64</env-entry-value>
</env-entry>
When I try and create the envCtx object I get a NamingException with the message that Name java:comp is not bound in this Context. I'm confused because it worked fine with Tomcat 6. Have I missed something in the setup of Tomcat 7 that I had previously defined in the setup of Tomcat 6?
Mark Thomas via the tomcat-users mailing list suggested
tomcat.enableNaming();
before the server is started. This worked for me (I guess they changed the default behaviour between 6 and 7).
