StandardJarScanner (Apache Tomcat 7.0.67 API Documentation)

java.lang.Object
- org.apache.tomcat.util.scan.StandardJarScanner

All Implemented Interfaces:

JarScanner
```
public class StandardJarScanner
extends java.lang.Object
implements JarScanner
```
The default JarScanner implementation scans the WEB-INF/lib directory followed by the provided classloader and then works up the classloader hierarchy. This implementation is sufficient to meet the requirements of the Servlet 3.0 specification as well as to provide a number of Tomcat specific extensions. The extensions are:
- Scanning the classloader hierarchy (enabled by default)
- Testing all files to see if they are JARs (disabled by default)
- Testing all directories to see if they are exploded JARs (disabled by default)
All of the extensions may be controlled via configuration.

    Scan the provided ServletContext and classloader for JAR files. Each JAR file found will be passed to the callback handler to be processed.
    
    Specified by:
    
    scan in interface JarScanner
    
    Parameters:
    context - The ServletContext - used to locate and access WEB-INF/lib
    classloader - The classloader - used to access JARs not in WEB-INF/lib
    callback - The handler to process any JARs found
    jarsToSkip - List of JARs to ignore. If this list is null, a default list will be read from the system property defined by Constants.SKIP_JARS_PROPERTY
