Hi,

I submitted a question two weeks ago regarding to the deployment of TDS 4.5.0. 
The symptom is: TDS fails to copy configuration files/folders from 
altContent/startup/ to TOMCAT_ROOT/, then TDS can't find xmls in 
content/thredds so I saw these in log file:

moteController.tdsContext; nested exception is 
org.springframework.beans.factory.BeanCreationException: Error creating bean 
with name 'tdsContext' defined in...
nested exception is java.lang.NullPointerException

Caused by: java.lang.NullPointerException
        at 
thredds.util.ThreddsConfigReader.getRootList(ThreddsConfigReader.java:62)
        at thredds.servlet.ThreddsConfig.init(ThreddsConfig.java:64)
        at 
thredds.server.config.TdsContext.afterPropertiesSet(TdsContext.java:369)

IMO, this is the consequence of missing config files in content/thredds folder. 
The real problem may reside at:

AbstractServlet.java:68
protected void initContent() throws javax.servlet.ServletException {

    // first time, create content directory
    String initialContentPath = ServletUtil.getInitialContentPath() + getPath();
    File initialContentFile = new File(initialContentPath);
    if (initialContentFile.exists()) {
      try {
        if (ServletUtil.copyDir(initialContentPath, contentPath))
          logServerStartup.info("copyDir " + initialContentPath + " to " + 
contentPath);
      } catch (IOException ioe) {
        logServerStartup.error("failed to copyDir " + initialContentPath + " to 
" + contentPath, ioe);
      }
    }
}

This function failed to copy content from altContent/startup/

I understand the implementation of this function probably is fine. It must be a 
setup issue on my end. But, I just can't find the problem myself. Here is the 
return from ps (I use jsvc over Tomcat 7.0 with APR, TDS version is 4.3 and 4.5)

jsvc.exec -java-home /usr/java/default -user tomcat -pidfile 
/var/lib/tomcat7054/logs/catalina-daemon.pid -wait 10 -outfile 
/var/lib/tomcat7054/logs/catalina-daemon.out -errfile &1 -classpath 
/var/lib/tomcat7054/bin/bootstrap.jar:/var/lib/tomcat7054/bin/commons-daemon.jar:/var/lib/tomcat7054/bin/tomcat-juli.jar
 -Djava.util.logging.config.file=/var/lib/tomcat7054/conf/logging.properties 
-Dtds.content.root.path=/var/lib/tomcat7054/content -Xmx1024m -Xms128m -server 
-Djava.awt.headless=true 
-Djava.util.prefs.systemRoot=/var/lib/tomcat7054/content/thredds/javaUtilPrefs 
-Djava.util.prefs.userRoot=/var/lib/tomcat7054/content/thredds/javaUtilPrefs 
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager 
-Djava.library.path=/var/lib/tomcat7054/lib/ -Djava.endorsed.dirs= 
-Dcatalina.base=/var/lib/tomcat7054 -Dcatalina.home=/var/lib/tomcat7054 
-Djava.io.tmpdir=/var/lib/tomcat7054/temp org.apache.catalina.startup.Bootstrap

You can tell I have tds.content.root.path, java.util.prefs.systemRoot and 
java.util.prefs.userRoot all point to the right location 
(/var/lib/tomcat7054/content). The tomcat user has full access to this content 
folder. In fact, I can see logs folder created under content/thredds/. But all 
other config files/folders were not there...

Please advise!

Thanks a lot!

Guan
