Na implementação do código para gerar empresas em xml, esta me retornando o seguinte erro: ago. 25, 2022 6:03:01 PM org.apache.catalina.core.StandardWrapperValve invoke SEVERE: Servlet.service() for servlet [br.com.alura.gerenciador.servlet.EmpresasService] in context with path [/gerenciador] threw exception [Servlet execution threw an exception] with root cause java.lang.NoClassDefFoundError: Could not initialize class com.thoughtworks.xstream.converters.extended.DynamicProxyConverter at com.thoughtworks.xstream.XStream.setupConverters(XStream.java:1002) at com.thoughtworks.xstream.XStream.(XStream.java:592) at com.thoughtworks.xstream.XStream.(XStream.java:514) at com.thoughtworks.xstream.XStream.(XStream.java:483) at com.thoughtworks.xstream.XStream.(XStream.java:429) at com.thoughtworks.xstream.XStream.(XStream.java:368) at br.com.alura.gerenciador.servlet.EmpresasService.service(EmpresasService.java:31) at javax.servlet.http.HttpServlet.service(HttpServlet.java:764) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:227) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:162) at org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:53) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:189) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:162) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:197) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:97) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:541) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:135) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:92) at org.apache.catalina.valves.AbstractAccessLogValve.invoke(AbstractAccessLogValve.java:687) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:78) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:360) at org.apache.coyote.http11.Http11Processor.service(Http11Processor.java:399) at org.apache.coyote.AbstractProcessorLight.process(AbstractProcessorLight.java:65) at org.apache.coyote.AbstractProtocol$ConnectionHandler.process(AbstractProtocol.java:890) at org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun(NioEndpoint.java:1789) at org.apache.tomcat.util.net.SocketProcessorBase.run(SocketProcessorBase.java:49) at org.apache.tomcat.util.threads.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1191) at org.apache.tomcat.util.threads.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:659) at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) at java.base/java.lang.Thread.run(Thread.java:833)
instruções que geraram o erro:
XStream xstream = new XStream();
String xml = xstream.toXML(empresas);
response.setContentType("application/xml");
response.getWriter().print(xml);
Pode me dar uma orientação??
