rest - A message body writer for Java class java.util.ArrayList, and Java type class java.util.ArrayList, and MIME media type application/json was not found -

i new using jersy implementing rest api

i below error, when call products service.

 com.sun.jersey.api.messageexception: message body writer java class java.util.arraylist, , java type class java.util.arraylist, , mime media type application/json not found. 

here code:

@get @path("/products") @produces(mediatype.application_json) public response productsearch(@queryparam("name") string name) {    list<product> products = new arraylist<>();    products.add(new product("prdname", "prdcost", "prdmodel"));    return response.ok( products).build(); } 

i tried this:

@get @path("/products") @produces(mediatype.application_json) public list<product> productsearch(@queryparam("name") string name) {    list<product> products = new arraylist<>();    products.add(new product("prdname", "prdcost", "prdmodel"));    return products; } 

the below setup of environment:

• tomcat 8,
• jersey libraries: jersey-bundle-1.19.1,
• not using maven

web.xml:

    <servlet>         <servlet-name>jersey-serlvet</servlet-name>         <servlet-class>com.sun.jersey.spi.container.servlet.servletcontainer</servlet-class>         <init-param>             <param-name>com.sun.jersey.config.property.packages</param-name>             <param-value>org.test.rest</param-value>         </init-param>         <load-on-startup>1</load-on-startup>     </servlet>      <servlet-mapping>         <servlet-name>jersey-serlvet</servlet-name>         <url-pattern>/rest/*</url-pattern>     </servlet-mapping> 

i tried using below init-param also:

    <init-param>         <param-name>com.sun.jersey.api.json.pojomappingfeature</param-name>         <param-value>true</param-value>       </init-param> 

i tried returning genericentity, had same issue.

return response.ok().entity(new genericentity<list<product>>(products) {}).build(); 

i tried using

• jersey-core-1.8.jar
• jersey-json-1.8.jar
• jersey-server-1.8.jar

instead of jersey-bundle-1.19.1

i don't have issues when return string. understand, missing json media type dependency, not figure out.

this error happens on tomcat server while client doesn't receive response obviously.
