将嵌入式Tomcat从v6更改为v7会导致InitialContext查找失败 [英] Changing embedded Tomcat from v6 to v7 causes InitialContext lookup to fail

问题描述

我正在使用JUnit测试用例来使用嵌入式Tomcat来运行我的Web服务.在Tomcat 6下，一切都工作正常，但是当我将项目切换到Tomcat 7时，我将无法使用.

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.

设置嵌入式Tomcat服务器的测试代码如下:

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();

由于嵌入式API在版本6和版本7之间进行了更改，因此我将自己的代码更改为以下内容:

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();

当我执行JUnit测试时，实际的Web服务可以正常启动(我可以使用我的Web浏览器并看到正在提供WSDL).

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).

但是，在我的Web服务的构造函数中，我根据web.xml文件(位于System.getProperty("user.dir")+"/build/web/WEB-INF/web.xml"中)的值初始化一些变量，如下所示:

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");

我的web.xml文件包含以下条目:

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>

当我尝试创建envCtx对象时，我得到了 NamingException 和消息Name java:comp is not bound in this Context.我很困惑，因为它可以在Tomcat 6上正常工作.我错过了以前在Tomcat 6设置中定义的Tomcat 7设置吗?

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?

推荐答案

通过tomcat-users邮件列表标记Thomas，

Mark Thomas via the tomcat-users mailing list suggested

tomcat.enableNaming();

在启动服务器之前.这对我有用(我想他们将默认行为更改为6到7).

before the server is started. This worked for me (I guess they changed the default behaviour between 6 and 7).
