javax.naming.NameNotFoundException：CDIExtension

标签： java spring jersey websphere-liberty

我使用com.sun.jersey.spi.spring.container.servlet.SpringServlet创建了两个Jersey servlet项目。我用的是平针织物1.19.1罐子。这两个项目都有lib文件夹中的依赖jar。我在自由9服务器中部署了这两个项目 当我尝试访问端点时，一个项目工作正常但不是另一个项目。如果第二个项目不起作用，我在控制台中有以下异常。如果我单独重启该项目（而不是服务器），它就可以工作。我不知道为什么，我试图找到永久解决方案。

  

SRVE0271E：应用程序[secondproject]中servlet [jersey-servlet]创建的未捕获的init（）异常：java.lang.RuntimeException：javax.naming.NameNotFoundException：CDIExtension

     

SRVE0315E：发生异常：java.lang.Throwable：javax.servlet.ServletException：SRVE0207E：servlet创建的未捕获初始化异常

如果第一个项目不起作用，我会在控制台中看到以下异常。

SRVE0271E：应用程序[firstproject]中servlet [jersey-servlet]创建的未捕获的init（）异常：java.lang.ClassCastException：com.sun.jersey.server.impl.cdi.CDIExtension与com.sun.jersey不兼容.server.impl.cdi.CDIExtension

SRVE0276E：初始化Servlet时出错[jersey-servlet]：javax.servlet.ServletException：SRVE0207E：servlet创建的未捕获初始化异常

使用完整堆栈更新：

请检查this link，这对我有帮助。

您可以在设置系统属性时解决问题 com.sun.jersey.server.impl.cdi.lookupExtensionInBeanManager=true

这可以从GlassFish服务器控制台完成。

  1. 选择节点 - ＆gt; Configuration-＆gt; server-config-＆gt; JVM设置 切换到“JVM选项”选项卡

  2. 添加新条目

    -Dcom.sun.jersey.server.impl.cdi.lookupExtensionInBeanManager =真

  3. 重启服务器

答案 1 :(得分：0)

在日志中，您可以看到：

Caused by: java.lang.ClassCastException: com.sun.jersey.server.impl.cdi.CDIExtension incompatible with com.sun.jersey.server.impl.cdi.CDIExtension

Liberty使用Jersey作为JAX-RS提供程序，因此您会遇到冲突。您必须从应用程序中删除这些jar，或者确保未在server.xml中显式或隐式包含JAX-RS功能

答案 2 :(得分：0)

错误

javax.naming.NameNotFoundException: Unable to resolve 'com.sun.jersey.config.CDIExtension'. Resolved 'com.sun.jersey.config'; remaining name 'CDIExtension'

可能是由于EJB3中的类导入引起的 示例：

import javax.enterprise.context.RequestScoped;

@RequestScoped
public class SampleServices {

@EJB
CalcBeanLocal calcBean;
.....

导入 RequestScope 时，“ bean.xml”将添加到WEB-INF。

可以通过使用 @stateless 注释而不是@RequestScope并通过在WEB-INF中删除上面创建的“ bean.xml”来解决此问题。

示例：

@stateless
public class SampleServices {

@EJB
CalcBeanLocal calcBean;
.....
