Lấy "java.lang.ClassNotFoundException: javax.servlet.http.HttpServlet" trong Eclipse + jboss 5.1.0

Question

Tôi đang cố gắng để có được một dự án RestEasy đơn giản để làm việc trong Eclipse (với Jboss Tools) và Jboss 5.1.0 . Để bắt đầu, tôi đã tạo một Dự án Web động đơn giản. Trong dự án này, tôi đã bao gồm trong WEB-INF/web.xml:

<context-param> 
    <param-name>resteasy.scan</param-name> 
    <param-value>true</param-value> 
</context-param> 
<listener> 
    <listener-class>org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap</listener-class> 
</listener> 

<servlet> 
    <servlet-name>Resteasy</servlet-name> 
    <servlet-class>org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher</servlet-class> 
</servlet> 

<servlet-mapping> 
    <servlet-name>Resteasy</servlet-name> 
    <url-pattern>/*</url-pattern> 
</servlet-mapping> 

Mở cố gắng để bắt đầu dự án trên (trong Jboss chạy trong Eclipse), tôi nhận được ngoại lệ sau đây trong Console:

Điều gì có thể gây ra lỗi này?

Xin cảm ơn trước.

Answer 1

Đầu tiên của RestEasy chỉ được hỗ trợ ra khỏi hộp từ phiên bản 6 của JBoss IIRC.

Có liên kết đến trang web dễ dàng còn lại nếu bạn cần tải xuống. http://www.jboss.org/resteasy

1. I make the assumption that you allready have a Preferences>Server>Runtime Environment> configured for JBoss. If not do that first.

2. Caused by: java.lang.NoClassDefFoundError: javax/servlet/http/HttpServlet. This tells me that if you got 1 above right you have not added it to your buildpath yet as Properties>Java Build Path>Add Library>Server Runtime. The runtime contains the servletapi.

3. org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap lives in the resteasy-jaxrs-2.3.0.GA.jar jar. Dump it in your WEB_INF/lib folder. DO NOT add it to your build path via Eclipse. Eclipse takes care of that it self.

4. org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher. Same as 3 above.

5. <param-name>resteasy.scan</param-name> This functionality I believe is a runtime dependency and lives in the scannotation-1.0.3.jar. Dump it in WEB_INF/lib. Again, Eclipse takes care of the classpath.

6. This is after all a JAX-RS project so dump jaxrs-api-2.3.0.GA.jar to your in WEB_INF/lib. This will bring in the @Path, @Get, etc annotations for use in your resource classes.

7. I also have jaxb-api-2.2.3.jar, javassist-3.8.0.GA.jar and jackson-jaxrs-1.8.5.jar in my WEB-INF/lib but from here on out it depends what functionality you are going to use and which providers loggers etc.

---

Tôi hy vọng tôi đóng đinh các yếu tố cần thiết lọ, nếu có ai điểm một thiếu một hãy sửa lại. Lần thử đầu tiên của tôi tại JAX-RS Tôi vừa đổ hết toàn bộ shebang 56 lọ trong WEB-INF/lib (Không phải là ý tưởng hay)

Hãy vui vẻ !!
