Question

我正在尝试在Eclipse（使用Jboss Tools）和Jboss 5.1.0中使用一个简单的RestEasy项目。为了开始，我创建了一个简单的动态Web项目。在项目中，我在WEB-INF / web.xml中包含以下内容：

<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>

在尝试启动上述项目时（在Eclipse中运行的Jboss中），我在控制台中收到以下异常：

14:10:17,614 ERROR [AbstractKernelController] Error installing to Real: name=vfsfile:/Users/groove/Documents/workspace/.metadata/.plugins/org.jboss.ide.eclipse.as.core/JBoss_5.1_Runtime_Server1326046666357/deploy/blankWeb.war/ state=PreReal mode=Manual requiredState=Real

可能导致此错误的原因是什么？

提前致谢。

Answer 1

第一个RestEasy仅支持JBoss IIRC版本6的包装盒。

如果您确实需要下载，请访问其他简易网站的链接。 http://www.jboss.org/resteasy

我假设你已经拥有了   为JBoss配置的首选项＆gt;服务器＆gt;运行时环境＆gt; 。如果不是先这样做。



引起：java.lang.NoClassDefFoundError：javax / servlet / http / HttpServlet。这告诉我，如果你有1   在右上方你还没有将它添加到你的构建路径中   属性＆gt; Java构建路径＆gt;添加库＆gt;服务器运行时。运行时包含servletapi。



org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap 生活在 resteasy-jaxrs-2.3.0.GA.jar jar中。将它转储到你的   WEB_INF / lib文件夹。不要通过Eclipse将它添加到构建路径中。   Eclipse负责自己。



org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher。与上述3相同。



<param-name>resteasy.scan</param-name>我相信这个功能是一个运行时依赖，并且存在于   的 scannotation-1.0.3.jar 即可。将其转储到WEB_INF / lib中。同样，Eclipse负责类路径。



这毕竟是一个JAX-RS项目，所以将 jaxrs-api-2.3.0.GA.jar 转储到WEB_INF / lib中。这将引入 @ Path，@ Get等注释，以便在您的资源类中使用。



我还有 jaxb-api-2.2.3.jar ， javassist-3.8.0.GA.jar 和 jackson-jaxrs- 1.8.5.jar 在我的WEB-INF / lib中，但是从现在开始它取决于你将使用什么功能以及哪些提供商   记录器等。

我希望我钉上必需品罐子，如果有人找到丢失的罐子，请更正。我在JAX-RS上的第一次尝试我只是将整个shebang的56个罐子丢弃在WEB-INF / lib中（不是一个好主意）

玩得开心!!

获取＆＃34; java.lang.ClassNotFoundException：javax.servlet.http.HttpServlet＆＃34;在Eclipse + jboss 5.1.0中
