部署时出现WebLogic 12.2.1 NullPointerException
[英]WebLogic 12.2.1 NullPointerException on deploy
问题描述
I'm developing a REST application using WebLogic 12.2.1 and NetBeans. 
我正在使用WebLogic 12.2.1和NetBeans开发REST应用程序。
Inside NetBeans, I'm using the local host and deploying without problems. 在NetBeans内部，我正在使用本地主机，并且部署没有问题。
When I use the Orcacle WebLogic admin tool, the system throws a NullPointerException. 当我使用Orcacle WebLogic管理工具时，系统将引发NullPointerException。
Here is the ApplicationConfig: 这是ApplicationConfig：
import com.owlike.genson.ext.jaxrs.GensonJsonConverter;
import javax.ws.rs.ApplicationPath;
import org.glassfish.jersey.server.ResourceConfig;
/**
*
* @author Leandro.Tietbohl
*/
@ApplicationPath("service")
public class ApplicationConfig extends ResourceConfig {
public ApplicationConfig() {
register(GensonJsonConverter.class);
packages("br.com.sicredi.programassociais.rest.service");
}
}
Here is the weblogic.xml: 这是weblogic.xml：

Here is the stacktrace: 这是堆栈跟踪：

The problem is relative to the method createApplicationBaseUriForServletMappings visible in the stacktrace. 该问题与在堆栈跟踪中可见的createApplicationBaseUriForServletMappings方法有关 。 The null-pointer is due to a missing mapping definition. 空指针归因于缺少映射定义。
No mappings is defined in the web.xml file for the ApplicationConfig servlet. 在web.xml文件中没有为ApplicationConfig servlet定义任何映射。 Il you add a mapping, this should work fine. 你添加一个映射，这应该工作正常。
<servlet-mapping>
<servlet-name>ApplicationConfig</servlet-name>
<url-pattern>/yourPathHere</url-pattern>
</servlet-mapping>
