Java 无法启动应用程序：JNLP错误

我找到了这个问题的答案

但是，我尝试通过选中“在我的计算机上保留临时文件”来启用java缓存 但我还是有个例外：

com.sun.deploy.net.JARSigningException: Found unsigned entry in resource: http://localhost:8080/<context-root>/client/servlet-api.jar

还有其他可能的解决方案吗？

为什么客户端代码需要servlet-api.jar？那个Jar是数字签名的吗？实际上，客户端是我的文件夹名。很抱歉。不，未签名，但其他JAR均未签名。不，未签名。。JWS发布的任何应用程序的所有代码。需要数字签名！如何签署jnlp jar？如何签署jnlp jar？和你想的完全一样。哦，请不要把它误认为是服务台。在提问之前做一些调查。
