Velocity and Classpath Mega-woes

[jopaki]

'lo all,

I'm using velocity to render pages in the web tier using spring under jboss 4.0.1 deployed as a simple war file. Here is the velocity specific app config:

  <bean id="velocityConfigurer" class="org.springframework.web.servlet.view.velocity.VelocityConfigurer">
    <property name="configLocation">
      <value>WEB-INF/velocity.properties</value>
    </property>
  </bean>
  
  <bean id="viewResolver" class="org.springframework.web.servlet.view.velocity.VelocityViewResolver">
    <property name="suffix" value=".vm"/>
    <!--
    <property name="numberToolAttribute"><value>numbertool</value></property>
    <property name="dateToolAttribute"><value>datetool</value></property>
    -->
  </bean>

Here is velocity.properties (located under WEB-INF):

# Any property that is not listed here will have it's default
# value used.  The default values are located in :
#  *  src/java/org/apache/velocity/runtime/default/velocity.defaults
#  *  http://jakarta.apache.org/velocity/developer-guide.html
#

runtime.log = ./velocity.log
runtime.log.logsystem.class=org.apache.velocity.runtime.log.SimpleLog4JLogSystem

resource.loader=file

#class.resource.loader.class=org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader
#class.resource.loader.cache=false
#class.resource.loader.modificationCheckInterval=2
#class.resource.loader.path=/WEB-INF/views

file.resource.loader.class=org.apache.velocity.runtime.resource.loader.FileResourceLoader
file.resource.loader.path=/WEB-INF/views
file.resource.loader.cache=true
file.resource.loader.modificationCheckInterval=2

Here is the error:

org.springframework.context.ApplicationContextException: Cannot find Velocity template for URL [admin-home.vm]: Did you specify the correct resource loader path?; nested exception is org.apache.velocity.exception.ResourceNotFoundException: Unable to find resource 'admin-home.vm'
org.apache.velocity.exception.ResourceNotFoundException: Unable to find resource 'admin-home.vm'

Here is the controller that is trying to invoke the velocity view:

public class AdminHomeController extends AbstractController {

  private AccountUserDao accountUserDao = null;
  
  public void setAccountUserDao(AccountUserDao accountUserDao) {
    this.accountUserDao = accountUserDao;
  }
  
  protected ModelAndView handleRequestInternal(HttpServletRequest request, HttpServletResponse response) throws Exception {
    
    long userId = RequestUtils.getRequiredLongParameter(request, "userId");
    
    // debug
    File f = new File(".");
    logger.debug("current dir absolute path ('.'): " + f.getAbsolutePath());
    ClassLoader classLoader = this.getClass().getClassLoader();
    URL url = classLoader.getResource(".");
    logger.debug("classLoader current dir: " + url.getPath() );
    ///
    
    AccountUserVO accountUser = accountUserDao.load(userId);
    
    return new ModelAndView("admin-home").addObject("accountUser", accountUser);
  }

Here is the logger output for the debug section w/in the controller class above:

22:28:49,414 DEBUG [AdminHomeController] current dir absolute path ('.'): C:\development\jboss-4.0.1\bin\.
22:28:50,926 DEBUG [AdminHomeController] classLoader current dir: /C:/development/jboss-4.0.1/server/default/tmp/deploy/tmp933smbiz-exp.war/

Does the war need some additional bit of info to tell JBoss what the "current directory" should be?

You can't rely on file system resources within a web application. I would recommend putting your templates in the classes/ directory, perhaps in another folder called templates, and using the ClassPathResourceLoader.

I googled for this problem and found this answer.

Now the *.vm files are put into the WEB-INF/classes folder and the web application works fine!!!!

Thanks again!
