Grouper Developers Forum

[Arnaud Deman <>]

Hello Chris,

The versions are : Grouper 1.6.3, Java Sun jdk 64 bits 1.6.0_24 and Tomcat 6. 
 

The correction I made was to delete the static member ORIGINAL_TMP_DIR
in the class EhcacheController and to use a local variable instead in
the methods :
EhcacheController::initialize() 
and
Hib3DAO::initHibernateIfNotInitted()

With this correction the property is not deleted but if I have well 
understood 
these methods are called when the Grouper API (via web service in ou case) is 
used at the first time. 
So I wonder if there is not still a problem if another processus uses the 
java.io.tmpdir
property at the same time.

Thanks,
Arnaud.

Example for  EhcacheController::initialize() :

 public void initialize() {
    if (this.mgr == null) {
      synchronized(EhcacheController.class) {
        final String prevTmpDir = System.getProperty(JAVA_IO_TMPDIR);
        if (this.mgr == null) {
          URL url = this.getClass().getResource("/grouper.ehcache.xml");
          if (url == null) {
            throw new RuntimeException("Cant find resourse 
/grouper.ehcache.xml, " +
                "make sure it is on the classpath");
          }
          
          //trying to avoid warning of using the same dir
          try {
            String newTmpdir = StringUtils.trimToEmpty(prevTmpDir);
            if (!newTmpdir.endsWith("\\") && !newTmpdir.endsWith("/")) {
              newTmpdir += File.separator;
            }
            newTmpdir += "grouper_ehcache_auto_" + GrouperUtil.uniqueId();
            System.setProperty(JAVA_IO_TMPDIR, newTmpdir);
            
            synchronized(CacheManager.class) {
              //now it should be using a unique directory
              this.mgr = new CacheManager(url);
            }
          } finally {
            //put tmpdir back
            if (prevTmpDir == null) {
              System.clearProperty(JAVA_IO_TMPDIR);
            } else {
              System.setProperty(JAVA_IO_TMPDIR, prevTmpDir);
            }
          }
          
        }
      }
    }
  }
