integrate configurable logging 2010-11-18 Omair Majid <omajid@redhat.com> * netx/net/sourceforge/jnlp/runtime/DeploymentConfiguration.java: Add KEY_ENABLE_LOGGING. (loadDefaultProperties): Use KEY_ENABLE_LOGGING. * netx/net/sourceforge/jnlp/runtime/JNLPRuntime.java: Add redirectStreams, STDERR_FILE and STDOUT_FILE. (initialize): Call initializeStreams. (initializeStreams): New method. Redirects or duplicates stdout and stderr to the logging files as required. (setRedirectStreams): New method. Sets whether stdout/stderr streams should be redirected. * plugin/icedteanp/java/sun/applet/PluginMain.java: (PluginMain): Move code for creating logging files into JNLPRuntime. Call JNLPRuntime.setRedirectStreams to redirect streams. (TeeOutputStream): Move to its own class. * netx/net/sourceforge/jnlp/util/TeeOutputStream.java: Moved from PluginMain into this new class.
