getTemplate() Nullpointer but Velocity is initialised - HELP

Hi,

I would very much appreciate some help, this deployment problem has driven
me almost mad for the last couple of days.

I'm using Struts Menu with a Velocity Macro (Velocity 1.4) as the renderer.
All works fine in Windows o/s with both Tomcat Version 5.5.20 or Jetty - BUT
when I deploy to Unix running Tomcat 5.5.17 I get a NullPointerException
when getTemplate() is called (I think the template name is
menuItemCommon.vm) matching the config=  see below) 

nav.jsp :- 

		<menu:useMenuDisplayer name="Velocity" config="menuItemCommon.vm"
permissions="rolesAdapter">
		  <menu:displayMenu name="UploadFile"/>
		  <menu:displayMenu name="WorkInProgress"/>
		</menu:useMenuDisplayer>

Reading the mailing list it sounded like Velocity may not be initialised,
but the Tomcat logs show that it is. We were already using Spring's
org.springframework.ui.velocity.VelocityEngineFactoryBean as we use Velocity
for email templates, so we already have :- 

    <bean id="velocityEngine"
          class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
        <property name="velocityProperties">
            <props>
                <prop key="resource.loader">class</prop>
                <prop key="class.resource.loader.class">
                   
org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader
                </prop>
                <prop key="velocimacro.library"></prop>
            </props>
        </property>
    </bean>

Stacktraces and logs are at the end of this post. 

I thought the The Velocity Macro 'menuItemCommon.vm' perhaps was not being
found, so I now have made sure it is in WEB-INF/classes and the root of
WEB-INF  but I still get this error - but as I say it only goes wrong in
unix environment with tomcat 5.5.17. 

The Struts Menu source where it goes wrong is :-

  protected void displayComponents(MenuComponent menu)
    throws JspException, IOException {
        HttpServletRequest request = (HttpServletRequest)
pageContext.getRequest();
        Template t;

        try {
            String template = getConfig();

            if (template == null) {
                throw new JspException("You must specify a template using
the 'config' attribute.");
            } else {
                log.debug("using template: " + template);
            }

            t = velocityEngine.getTemplate(template);
        } catch (Exception e) {
            String msg = "Error initializing Velocity: " + e.toString();
            log.error(msg, e);
            throw new JspException(msg, e);
        }


Here is the log of Velocity initializing :-

Re: Re: getTemplate() Nullpointer but Velocity is initialised - HELP

Posted by PeteTh <pe...@gmail.com>.
Setting 

runtime.log=logs/velocity.log

in velocity.properties  seems to work fine, we'd rather have all the logs in
one place.

thanks again

well, if you can't simply find a way to give the proper permissions to
access the tomcat log file, then yes, you will need to set up a
velocity.properties that tells the VelocityEngine used by StrutsMenu
to log somewhere where it does have permission.  however, it requires
more than just setting the runtime.log property, as that is ignored by
the ServletLogger.  you'll need to tell that engine to use an entirely
different log system.  see the following for more info:

Many thanks. 

Yes there were two exceptions, I had ignored the earlier one thinking it was
unimportant - but I see now it was causing Velocity to not initialise - but
then the code execution continued then getting NullPointer much later on
....

The first exception was just a permission denied when trying to write to the
velocity.log :-

21 Aug 2007 10:16:27 [main] ERROR
net.sf.navigator.displayer.VelocityMenuDisplayer  - Error initializing
Velocity: Unable to configure AvalonLogSystem :
java.io.FileNotFoundException: /usr/share/tomcat55/velocity.log (Permission
denied) 


For some reason the log is being written to /usr/var/tomcat55   
top directory rather than the /logs subdirectory.  

I see in Struts Menu velocity init there is, then it looks for a
velocity.properties on themclasspath  :- 

  // default to servletlogger, which logs to the servlet engines log
       
velocityEngine.setProperty(RuntimeConstants.RUNTIME_LOG_LOGSYSTEM_CLASS,
                             ServletLogger.class.getName());

I will try setting up a velocity.properties with

runtime.log=logs/velocity.log

maybe that is what is needed ?

nothing intrinsically wrong with using multiple engines, as long as
they're both set up properly.  the code below does give a hint
though...

it all looks good up to here.  but here, we see that if any Exception
is thrown above, then the actual call to velocityEngine.init() never
finishes, the exception is logged, and then the application is allowed
to continue!   this is poorly written, because an uninitialized
VelocityEngine (at least in Velocity 1.4) is a *major* problem.  they
need to either let the exceptions go, throw a new wrapping exception,
or else try again to init the engine.

it certainly looks like some exception is thrown either prior to or
during the call to init(props).  can you find this Exception in your
logs?

Re: Re: getTemplate() Nullpointer but Velocity is initialised - HELP

Posted by PeteTh <pe...@gmail.com>.
I have also posted on the Struts Menu mailing list but no response at there. 

I'm sure its something to do with using Velocity twice in an app, I have
also found the src code in Struts Menu where Velocity init() is called :- 

public class VelocityMenuDisplayer extends MessageResourcesMenuDisplayer {
    protected static final Log log =
LogFactory.getLog(VelocityMenuDisplayer.class);
    private static VelocityEngine velocityEngine = new VelocityEngine();
    private PageContext pageContext = null;

    public static void initialize(ServletContext context) {
       
velocityEngine.setApplicationAttribute(ServletContext.class.getName(),
context);

        // default to servletlogger, which logs to the servlet engines log
       
velocityEngine.setProperty(RuntimeConstants.RUNTIME_LOG_LOGSYSTEM_CLASS,
                             ServletLogger.class.getName());

        // by default, load resources with webapp resource loader
        velocityEngine.setProperty(RuntimeConstants.RESOURCE_LOADER,
"webapp");
        velocityEngine.setProperty("webapp.resource.loader.class",
WebappLoader.class.getName());

        // now all is ready - init Velocity
        try {
            Properties props = new Properties();
            ResourceBundle defaults =
ResourceBundle.getBundle("net.sf.navigator.displayer.velocity");
            for (Enumeration keys = defaults.getKeys();
keys.hasMoreElements();) {
                String key = (String) keys.nextElement();
                props.put(key, defaults.getString(key));
            }

            // look to see if the user has overridden velocity.properties by
            // placing velocity.properties in WEB-INF/classes
            ResourceBundle custom = null;

            try {
                custom = ResourceBundle.getBundle("velocity");
                for (Enumeration keys = custom.getKeys();
keys.hasMoreElements();) {
                    String key = (String) keys.nextElement();
                    props.put(key, custom.getString(key));
                }
            } catch (MissingResourceException mre) {
                log.debug("No velocity.properties found in classpath, using
default settings");
            }

            velocityEngine.init(props);
        } catch (Exception e) {
            log.error("Error initializing Velocity: " + e.getMessage());
            e.printStackTrace();
        }
    }

Any further thoughts ?

Re: getTemplate() Nullpointer but Velocity is initialised - HELP

Posted by Nathan Bubna <nb...@gmail.com>.
I looked at line 831 of Velocity 1.4's RuntimeInstance, and
unfortunately, the only possible way to get an NPE there is if that
RuntimeInstance was not initialized.

Since there is some RuntimeInstance being initialized (according to
the Tomcat logs), it appears that the problem is that the instance
VelocityMenuDisplayer is trying to use has not been initialized.  I'm
not familiar with StrutsMenu, so i don't know how it is getting its
VelocityEngine.   All i can say is that the VelocityEngine it is
trying to use has not been initialized, regardless of whether or not
some other one has been initialized.
