应用程序服务器类路径-Linux中的Java库

Question

How to check the list of libraries (jar, properties,folders) that is in the classpath of the application which is running in the application server(webpshere 8.1)?

Does ps (process) command in linux gives all the details. And also , How do we checking the port number(http,admin console,soap) of the application /application server domains?

Aside from WEB-INF/lib ,WEB-INF/classes. which are the folders that application server takes deafault into classpath.

My question is to find out the libraries that are used by server to run the application.

Answer 1

To know which jars are loaded into the JVM. In most conditions, 'lsof' can help you:

lsof -a -p < pid > |grep '\\.jar'

Answer 2

You should use the Class viewer service to find out what jar files and libraries reside on the classpath.

Answer 3

I am not aware of the existence of WAS 8.1. However, application classloader in WAS can output all libraries that were loaded. Simply call toString() on it from within any class of the application:

System.out.println(getClass().getClassLoader().toString())

Answer 4

I don't know how to specify java command line parameters for websphere, but for the standard JVM, if you want to see where the class files are loaded from, you can specify the -verbose:class parameter. Assuming websphere is using a standard JVM at some point, that should help.
