DOS上的Java命令

Question

with javap java.lang.Object we are able to see the methods signature under it, where as with javap javax.servlet.ServletConfig we are not able to see it.

Could any one please suggest any command for checking the method signatures for javax.servlet.ServletConfig

Answer 1

I don't know if you specifically want a local tool to find the signature, however the best bet is always to look at the API documentation. A google search of the fully qualified class name leads straight to the official API documentation . This will not only show you the method signatures, but often give you valuable contextual information well beyond an argument name or type.

Answer 2

你应该做

java -cp <location-of-servlet-api-jar> javax.servlet.ServletConfig

Answer 3

You will need to locate your servlet-api.jar file and issue the following command:

javap -classpath javax.servlet.ServletConfig

substitute with the path to your servlet-api-.jar
