This example demonstrates how to throw and map exceptions using ExceptionMapper in Jersey resource classes.
The example consists of just one Jersey resource:
com.sun.jersey.samples.exceptions.MyResource
The mapping of the URI path space is presented in the following table:
URI path | Resource class | HTTP methods |
---|---|---|
/myresource | MyResource | GET |
/myresource/runtime | MyResource | GET |
/myresource/checked/ioexception | MyResource | GET |
/myresource/checked/mymappedexception | MyResource | GET |
/myresource/checked/mymappedruntimeexception | MyResource | GET |
/myresource/checked/mymappedthrowingexception | MyResource | GET |
/myresource/webapplicationexception/{status} | MyResource | GET |
Run the example as follows:
run
mvn clean compile exec:java
From a web browser, visit:
http://localhost:9998/myresource
http://localhost:9998/myresource/runtime?ex=java.lang.NullPointerException

http://localhost:9998/myresource/checked/ioexception
