Class MetaInfConfiguration

java.lang.Object

org.eclipse.jetty.webapp.AbstractConfiguration

org.eclipse.jetty.webapp.MetaInfConfiguration

All Implemented Interfaces:

Configuration

public class MetaInfConfiguration
extends AbstractConfiguration

MetaInfConfiguration Scan META-INF of jars to find:

• tlds
• web-fragment.xml
• resources

The jars which are scanned are:

1. those from the container classpath whose pattern matched the WebInfConfiguration.CONTAINER_JAR_PATTERN
2. those from WEB-INF/lib

Method Detail

preConfigure

public void preConfigure(WebAppContext context)
                  throws Exception

Description copied from interface: Configuration

Set up for configuration.

Typically this step discovers configuration resources

Specified by:

preConfigure in interface Configuration

Overrides:

preConfigure in class AbstractConfiguration

Parameters:

context - The context to configure

Throws:

Exception

scanJars

public void scanJars(WebAppContext context,
            Collection<Resource> jars,
            boolean useCaches)
              throws Exception

Look into the jars to discover info in META-INF. If useCaches == true, then we will cache the info discovered indexed by the jar in which it was discovered: this speeds up subsequent context deployments.

Parameters:

context -

jars -

useCaches -

Throws:

Exception

scanForResources

public void scanForResources(WebAppContext context,
                    Resource target,
                    ConcurrentHashMap<Resource,Resource> cache)
                      throws Exception

Scan for META-INF/resources dir in the given jar.

Parameters:

context -

target -

cache -

Throws:

Exception

scanForFragment

public void scanForFragment(WebAppContext context,
                   Resource jar,
                   ConcurrentHashMap<Resource,Resource> cache)
                     throws Exception

Scan for META-INF/web-fragment.xml file in the given jar.

Parameters:

context -

jar -

cache -

Throws:

Exception

scanForTlds

public void scanForTlds(WebAppContext context,
               Resource jar,
               ConcurrentHashMap<Resource,Collection<URL>> cache)
                 throws Exception

Discover META-INF/*.tld files in the given jar

Parameters:

context -

jar -

cache -

Throws:

Exception

postConfigure

public void postConfigure(WebAppContext context)
                   throws Exception

Description copied from interface: Configuration
