[Resin-interest] "java com.caucho.server.resin.Resin" and "java -jar resin.jar" behaves different

Thu, 06 Mar 2008 20:30:15 -0800 

Hi Scott,

I'm using IDEA resin plugin to debug webapp in resin.
At develepment stage, IDEA starts resin for me by command
C:\jdk1.6.0\bin\java -Djava.util.logging.manager=com.caucho.log.LogManagerImpl -DRESIN_HOME=C:\resin-pro-3.1 -Xmx512m -XX:PermSize=64M -XX:MaxPermSize=128m -classpath "C:\jdk1.6.0\lib\tools.jar;C:\resin-pro-3.1\lib\activation.jar;C:\resin-pro-3.1\lib\ejb-15.jar;C:\resin-pro-3.1\lib\hessian.jar;C:\resin-pro-3.1\lib\j2ee-management-10.jar;C:\resin-pro-3.1\lib\javamail-14.jar;C:\resin-pro-3.1\lib\jaxb-api.jar;C:\resin-pro-3.1\lib\jaxrpc-15.jar;C:\resin-pro-3.1\lib\jaxws-api.jar;C:\resin-pro-3.1\lib\jca-15.jar;C:\resin-pro-3.1\lib\jms-11.jar;C:\resin-pro-3.1\lib\jpa-15.jar;C:\resin-pro-3.1\lib\jsdk-15.jar;C:\resin-pro-3.1\lib\jsr88.jar;C:\resin-pro-3.1\lib\jstl-11.jar;C:\resin-pro-3.1\lib\jta-101.jar;C:\resin-pro-3.1\lib\jws-15.jar;C:\resin-pro-3.1\lib\license.jar;C:\resin-pro-3.1\lib\portlet-10.jar;C:\resin-pro-3.1\lib\pro.jar;C:\resin-pro-3.1\lib\quercus.jar;C:\resin-pro-3.1\lib\resin-deploy.jar;C:\resin-pro-3.1\lib\resin-util.jar;C:\resin-pro-3.1\lib\resin.jar;C:\resin-pro-3.1\lib\script-10.jar;C:\resin-pro-3.1\lib\webbeans-16.jar;C:\resin-pro-3.1\lib\webutil.jar;C:\resin-pro-3.1\lib\jtds-1.2.2.jar" com.caucho.server.resin.Resin -conf myapp.conf 

and it's ok.
At deployment stage I added resin to windows service by httpd.exe -install. When starting service exceptions ocurred. It did not happen before when using 3.1.5 alpha snapshot and earlier version, now I'm using the newest snapshot. 
I noticed that running command

   C:\jdk1.6.0\bin\java -jar ... lib/resin.jar -conf myapp.conf

will show me the same exception stack as well as runing command

   httpd.exe -conf myapp.conf
So I believed in that there maybe a bug in resin.jar but not in httpd.exe. httpd should be only a wrapper of java -jar resin.jar, also the watchdog.
Below is my stacktrace. I'm deploying my project with struts2.1.1 snapshot and xwork snapshot version.

I paste a code snippet of com.opensymphony.xwork2.validator.DefaultValidatorFactory below. ==========================line 90~128 of DefaultValidatorFactory.java============================ 
   private void parseValidators() {
       if (LOG.isDebugEnabled()) {
           LOG.debug("Loading validator definitions.");
       }

       List<File> files = new ArrayList<File>();
       try {
           // Get custom validator configurations via the classpath
line 98: Iterator<URL> urls = ClassLoaderUtil.getResources("", DefaultValidatorFactory.class, false); 
           while (urls.hasNext()) {
               URL u = urls.next();
File f = new File(new URI(u.toExternalForm().replaceAll(" ", "%20"))); 
               FilenameFilter filter = new FilenameFilter() {
                   public boolean accept(File file, String fileName) {
                       return fileName.contains("-validators.xml");
                   }
               };
line 107:       files.addAll(Arrays.asList(f.listFiles(filter)));
           }
       } catch (URISyntaxException e) {
           e.printStackTrace();

       // Parse default validator configurations

       retrieveValidatorConfiguration(resourceName);

       for (File file : files) {
           retrieveValidatorConfiguration(file.getName());
       }
   }
======================================================================================================

After some logging, I found "urls" got at line:98 were different between
"java com.caucho.server.resin.Resin" and "java -jar resin.jar".

Command "java com.caucho.server.resin.Resin":
urls (only one url):
   /C:/Projects/buysou_new/exploded/WEB-INF/classes/
It's correct.

Command "java -jar resin.jar":
urls (two urls):
   /C:/JDK1.6.0/jre/lib/ext/meta-index/
   /C:/Projects/buysou_new/exploded/WEB-INF/classes/
The first url will cause the exception.
================line 44~67of com.opensymphony.xwork2.util.ClassLoaderUtil.java========== public static Iterator<URL> getResources(String resourceName, Class callingClass, boolean aggregate) throws IOException { 

        AggregateIterator<URL> iterator = new AggregateIterator<URL>();

        
iterator.addEnumeration(Thread.currentThread().getContextClassLoader().getResources(resourceName));

        if (!iterator.hasNext() || aggregate) {
            
iterator.addEnumeration(ClassLoaderUtil.class.getClassLoader().getResources(resourceName));
        }

        if (!iterator.hasNext() || aggregate) {
            ClassLoader cl = callingClass.getClassLoader();

            if (cl != null) {
                iterator.addEnumeration(cl.getResources(resourceName));
            }
        }
if (!iterator.hasNext() && (resourceName != null) && (resourceName.charAt(0) != '/')) { return getResources('/' + resourceName, callingClass, aggregate); 
        }

        return iterator;    // I've found it always return normally
    }
======================================================================================================
It seems the Thread.currentThread().getContextClassLoader().getResources("") will produce the two urls, 
one of which is
   "/C:/JDK1.6.0/jre/lib/ext/meta-index/"

I've written a simple test and comfired it.
Should it be a bug of Resin.jar of httpd?

Regards,
- Wesley
