阅读更多关于 Tomcat 8 Examples: Missing Configuration Step

I'm trying to set up the "Echo" websocket example on Tomcat 8. I believe I am missing the step where you tell tomcat about the websocket classes. Here's what I have done: Created a new dynamic web project in Eclipse, added maven, and linked tomcat 8 runtimes Copied EchoAnotation.java, EchoEndpoint.java, ExamplesConfig.java, and echo.xhtml into the project. Started the app. When I start the app, I can navigate to the echo.xhtml file, but no matter what url I enter, I can't seem to figure out how to get to web sockets--I always get 404. Putting breakpoints in the constructors, it looks like the

getting Invalid byte tag in constant pool : 19

阅读更多关于 getting Invalid byte tag in constant pool : 19

i am creating one webservice and getting error like org.apache.tomcat.util.bcel.classfile.ClassFormatException: Invalid byte tag in constant pool: 19. i am using tomcat 8.0 and java versoin is 1.8.0.152. A constant pool entry with tag type 19 is a module descriptor; see JVM spec table 4.4-A . I think you have attempted to use BCEL on a class compiled with a Java 9 (or later) compiler: The BCEL version you are using doesn't understand the tag. The class wouldn't load in a Java 8 JVM anyway. Modules were only introduced in Java 9, and the class file's major version number should be too recent
