问题


Actually i am completely new in web service development. I am unable to run simple dynamic web service application using eclipse oxygen, tomcat 7, jersey library. i know there is so many solutions are available i have tried but nothing is working for me, I am unable to find out where i am making mistake.

this is my class.

package book;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
@Path("/book")
public class Book {
@GET
@Produces(MediaType.TEXT_XML)
public String sayHelloXML(){
    String response = "<?xml version='1.0'?>"+
            "<hello>Hello XML</hello>";
    return response;
}
}

this is web.xml file.

 <?xml version="1.0" encoding="UTF-8"?>

I am using this url

回答1:


The logs show that some dependencies are yet to be resolved (such as javax.json-api-1.1.jar, yasson-1.0.jar) Try adding those Jars in the Classpath. Moreover, you haven't provided the mapping '/sayHelloXML' for the function sayHelloXML().

From this bug page : Tomcat should skip or handle module-info.class when scanning for annotations, you can see that the bug is the same :

SEVERE: Unable to process Jar entry [module-info.class] from Jar [file:...../javax.json-1.1.0-M1.jar] for annotations
org.apache.tomcat.util.bcel.classfile.ClassFormatException: Invalid byte tag in constant pool: 19
at org.apache.tomcat.util.bcel.classfile.Constant.readConstant(Constant.java:97)
at org.apache.tomcat.util.bcel.classfile.ConstantPool.<init>(ConstantPool.java:54)
at org.apache.tomcat.util.bcel.classfile.ClassParser.readConstantPool(ClassParser.java:174)
at org.apache.tomcat.util.bcel.classfile.ClassParser.parse(ClassParser.java:83)

Job was in progress :

Although Tomcat code can be updated independently of BCEL, we must know what the code "19" means and thus how many bytes to skip (for the simple case if it can be ignored).

and

19 is CONSTANT_Module and 20 is CONSTANT_Package.

I don't see a reason to scan module-info for annotations at all. @WebServlet, @WebFilter, or @WebListener is not expected here anyway.

and

Looks like we just need to skip 2 bytes. The change needs to be implemented in Commons BCEL first and then back-ported to Tomcat.

and finally the bug has been fixed in following versions :

BCEL updated and back-port complete.

Fixed in:

  • trunk for 9.0.0.M18 onwards

  • 8.5.x for 8.5.12 onwards

  • 8.0.x for 8.0.42 onwards

  • 7.0.x for 7.0.76 onwards

So if you want to stick to Tomcat 7, upgrade to at least version 7.0.76 .
