/**
* 

* Description: This is the static weave command line processing class that verifies command options and invokes * StaticWeaveProcessor to statically weave the classes. *

Usage:
*  StaticWeave [options] source target
Options:
*  -classpath
*    Set the user class path, use ";" as the delimiter in Window system and ":" in Unix system.
*  -log
*    The path of log file, the standard output will be the default.
*  -loglevel
*    Specify a literal value for toplink log level(OFF,SEVERE,WARNING,INFO,CONFIG,FINE,FINER,FINEST). The default value is OFF.
*  -persistenceinfo
*    The path contains META-INF/persistence.xml. This is ONLY required when the source does not include it. * The classpath must contain all the classes necessary in oder to perform weaving.

* The weaving will be performed in place if source and target point to the same location. Weaving in place is ONLY applicable for directory-based sources.
*Example:
* To weave all entites contained in c:\foo-source.jar with its persistence.xml contained within c:\foo-containing-persistence-xml.jar, and output to c:\\foo-target.jar,
* StaticWeave -persistenceinfo c:\foo-containing-persistencexml.jar -classpath c:\classpath1;c:\classpath2 c:\foo-source.jar c:\foo-target.jar * **/ public class StaticWeave { // command line arguments private String[] argv; // The location path of the source, null if none was given private String source; // The location path containing persistence.xml, null if none was given private String persistenceinfopath; // The location path of the target, null if none was given private String target; private int loglevel=SessionLog.OFF; private Writer logWriter; private PrintStream vout = System.out; private String[] classpaths; public static void main(String[] argv) { StaticWeave staticweaver = new StaticWeave(argv); try { // Verify the command line arguments staticweaver.processCommandLine(); staticweaver.start(); } catch (Exception e) { throw StaticWeaveException.exceptionPerformWeaving(e); } } public StaticWeave(String[] argv) { this.argv = argv; } /** * Invoke StaticWeaveProcessor to perform weaving. */ public void start() throws Exception { //perform weaving StaticWeaveProcessor staticWeaverProcessor= new StaticWeaveProcessor(this.source,this.target); if(persistenceinfopath!=null){ staticWeaverProcessor.setPersistenceInfo(this.persistenceinfopath); } if(classpaths!=null){ staticWeaverProcessor.setClassLoader(getClassLoader()); } if(logWriter!=null){ staticWeaverProcessor.setLog(logWriter); } staticWeaverProcessor.setLogLevel(loglevel); staticWeaverProcessor.performWeaving(); } /* * Verify command line option. */ void processCommandLine() throws Exception { if (argv.length < 2 || argv.length>10) { printUsage(); System.exit(1); } for (int i=0;i= argv.length ){ printUsage(); System.exit(1); } classpaths=argv[i+1].split(File.pathSeparator); i++; continue; } if (argv[i].equalsIgnoreCase("-persistenceinfo")) { if ((i + 1) >= argv.length ){ printUsage(); System.exit(1); } persistenceinfopath=argv[i+1]; i++; continue; } if (argv[i].equalsIgnoreCase("-log")) { if ((i + 1) >= argv.length ){ printUsage(); System.exit(1); } logWriter=new FileWriter(argv[i+1]); i++; continue; } if (argv[i].equalsIgnoreCase("-loglevel")) { if ((i + 1) >= argv.length ) { printUsage(); System.exit(1); } if ( argv[i+1].equalsIgnoreCase("OFF") || argv[i+1].equalsIgnoreCase("SEVERE") || argv[i+1].equalsIgnoreCase("WARNING") || argv[i+1].equalsIgnoreCase("INFO") || argv[i+1].equalsIgnoreCase("CONFIG") || argv[i+1].equalsIgnoreCase("FINE") || argv[i+1].equalsIgnoreCase("FINER") || argv[i+1].equalsIgnoreCase("FINEST") || argv[i+1].equalsIgnoreCase("ALL")) { loglevel=AbstractSessionLog.translateStringToLoggingLevel(argv[i+1].toUpperCase()); } else{ printUsage(); System.exit(1); } i++; continue; } if(source!=null){ printUsage(); System.exit(1); } if(target!=null){ printUsage(); System.exit(1); } source=argv[i]; if((i+1)>=argv.length){ printUsage(); System.exit(1); } i++; if(i>=argv.length){ printUsage(); System.exit(1); } target=argv[i]; i++; } //Ensure source and target have been specified if(source==null){ printUsage(); throw StaticWeaveException.missingSource(); } if(target==null){ printUsage(); throw StaticWeaveException.missingTarget(); } } /* * print command help message */ private void printUsage() { PrintStream o = vout; o.println(ToStringLocalization.buildMessage("staticweave_commandline_help_message", new Object[]{null})); } /* * Convert the specified classpath arrary to URL array where new classloader will build on. */ private ClassLoader getClassLoader() throws MalformedURLException{ if (classpaths!=null){ URL[] urls= new URL[classpaths.length]; for(int i=0;i
