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

configure

public void configure(WebAppContext context)
               throws Exception

Description copied from interface: Configuration

Configure WebApp.

Typically this step applies the discovered configuration resources to either the WebAppContext or the associated MetaData.

Specified by:

configure in interface Configuration

Overrides:

configure in class AbstractConfiguration

Parameters:

context - The context to configure

Throws:

Exception

deconfigure

public void deconfigure(WebAppContext context)
                 throws Exception

Description copied from interface: Configuration

DeConfigure WebApp. This method is called to undo all configuration done. This is called to allow the context to work correctly over a stop/start cycle

Specified by:

deconfigure in interface Configuration

Overrides:

deconfigure in class AbstractConfiguration

Parameters:

context - The context to configure

Throws:

Exception

cloneConfigure

public void cloneConfigure(WebAppContext template,
                  WebAppContext context)
                    throws Exception

Description copied from interface: Configuration

Clone configuration instance.

Configure an instance of a WebAppContext, based on a template WebAppContext that has previously been configured by this Configuration.

Specified by:

cloneConfigure in interface Configuration

Overrides:

cloneConfigure in class AbstractConfiguration

Parameters:

template - The template context

context - The context to configure

Throws:

Exception

See Also:

AbstractConfiguration.cloneConfigure(org.eclipse.jetty.webapp.WebAppContext, org.eclipse.jetty.webapp.WebAppContext)

resolveTempDirectory

public void resolveTempDirectory(WebAppContext context)
                          throws Exception

Get a temporary directory in which to unpack the war etc etc. The algorithm for determining this is to check these alternatives in the order shown:

A. Try to use an explicit directory specifically for this webapp:

1. Iff an explicit directory is set for this webapp, use it. Set delete on exit depends on value of persistTempDirectory.
2. Iff javax.servlet.context.tempdir context attribute is set for this webapp && exists && writeable, then use it. Set delete on exit depends on value of persistTempDirectory.

B. Create a directory based on global settings. The new directory will be called "Jetty-"+host+"-"+port+"__"+context+"-"+virtualhost+"-"+randomdigits+".dir"

If the user has specified the context attribute org.eclipse.jetty.webapp.basetempdir, the directory specified by this attribute will be the parent of the temp dir created. Otherwise, the parent dir is $(java.io.tmpdir). Set delete on exit depends on value of persistTempDirectory.

Throws:

Exception

makeTempDirectory

public void makeTempDirectory(File parent,
                     WebAppContext context)
                       throws Exception

Throws:

Exception

configureTempDirectory

public void configureTempDirectory(File dir,
                          WebAppContext context)

unpack

public void unpack(WebAppContext context)
            throws IOException

Throws:

IOException

getCanonicalNameForWebAppTmpDir

public static String getCanonicalNameForWebAppTmpDir(WebAppContext context)

Create a canonical name for a webapp temp directory. The form of the name is: "jetty-"+host+"-"+port+"-"+resourceBase+"-_"+context+"-"+virtualhost+"-"+randomdigits+".dir" host and port uniquely identify the server context and virtual host uniquely identify the webapp randomdigits ensure every tmp directory is unique

Returns:

the canonical name for the webapp temp directory
