Velocity Template Location

[zegloman]

Hello,

I am getting a NullPointerException with VelocityEngineUtils.
org.springframework.ui.velocity.VelocityEngineUtil s.mergeTemplate(VelocityEngineUtils.java:55)
I am guessing it can't find the template.

I am trying to merge a template so I can email the result.

Here is my applicationContext.xml snippet:

  <!-- Mail Confiruguration -->
  <bean id="velocityEngine" class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
    <property name="resourceLoaderPath"><value>/WEB-INF/templates</value></property>
  </bean>
  
  <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
    <property name="host"><value>mail.xxx.org</value></property>
    <property name="username"><value>xxx</value></property>
    <property name="password"><value>xxx</value></property>
  </bean>
  
  <bean id="mailMessage" class="org.springframework.mail.SimpleMailMessage"/>
  
  <bean id="managerTarget" class="com.xxx.MailSender">
    <property name="mailSender"><ref bean="mailSender"/></property>
    <property name="message"><ref bean="mailMessage"/></property>
    <property name="velocityEngine"><ref bean="velocityEngine"/></property>    
  </bean>

And the relevant Java Code:

        SimpleMailMessage msg = new SimpleMailMessage();
        msg.setFrom("lostpassword@xxx.org");
        msg.setSubject("Lost Password Request");
        msg.setTo(reg.getEmail());
        
        Map<String, Registrant> model = new HashMap<String, Registrant>&#40;&#41;;
        model.put&#40;"registrant", reg&#41;;

        String result = null;
        
        try
        &#123;
            result = VelocityEngineUtils.mergeTemplateIntoString&#40;velocityEngine,
                    "lostPassword.vm", model&#41;;
        &#125; 
        catch&#40;VelocityException e&#41;
        &#123;
            log.error&#40;e&#41;;
        &#125;
        
        msg.setText&#40;result&#41;;

        try
        &#123;
            mailSender.send&#40;msg&#41;;
        &#125; 
        catch &#40;MailException ex&#41;
        &#123;
            log.error&#40;ex&#41;;
        &#125;

Is there a way to figure out where Velocity is looking for the template?

Thanks

Try turning the logging on Velocity package (see this thread from the mailing list as a starting point: http://mail-archives.eu.apache.org/mod_mbox/jakarta-velocity-user/200501.mbox/%3c000001c4f71c$0421de90$310d3b80@mrl.cs.columbia. edu%3e)

Hello,

Still can't figure this out, Logging shows the velocity engine is started properly, do i need any other configuration?

Thanks

Did you find out a solution? I run into the same problem.
Thanks.

I encountered the same problem, too. Is there anyone can figure it out?
I'll be waiting.....

1. applicationContext:
<bean id="velocityEngine"
class="org.springframework.ui.velocity.VelocityEng ineFactoryBean">
<property name="velocityProperties">
<props>
<prop key="resource.loader">class</prop>
<prop key="class.resource.loader.class">
org.apache.velocity.runtime.resource.loader.Classp athResourceLoader
</prop>
</props>
</property>
</bean>
2. Code:
text = VelocityEngineUtils.mergeTemplateIntoString(veloci tyEngine,
"velocity/templates/xyz.vm", model);
3. deployment directories under zyx.jar:
/applicationContext.xml
/velocity/templates/xyz.vm

[elmalik_2006]

<bean id="velocityEngine" class="org.springframework.ui.velocity.VelocityEng ineFactoryBean">
<property name="resourceLoaderPath"><value>/WEB-INF/velocity</value></property>
</bean>


and in controller

String text = VelocityEngineUtils.mergeTemplateIntoString(veloci tyEngine, "shareImageTemplate.vm", model);

note your templates (.vm) under folder (/WEB-INF/velocity) as you are wrote in servlet.xml (<property name="resourceLoaderPath"><value>/WEB-INF/velocity</value>)

1. In appContext.xml define the location from where you want to pick up Velocity template.
<bean id="velocityEngine" class="org.springframework.ui.velocity.VelocityEng ineFactoryBean">
<property name="velocityProperties">
<props>
<prop key="resource.loader">file</prop>
<prop key="file.resource.loader.class">org.apache.veloci ty.runtime.resource.loader.FileResourceLoader
</prop>
<prop key="file.resource.loader.path">C:/Email/Velocity</prop>
<prop key="file.resource.loader.cache">true</prop>
<prop key="file.resource.loader.modificationCheckInterva l">0</prop>

</props>
</property>
</bean>

2. In AppProps.prop add Velocity template Name ( this will picked from folder given above).
htmlTemplate = emailBody.vm
3. Load AppProps.prop in classPath and create a Bean with getters and setters for this prop.
<contextroperty-placeholder file:C:/Email/AppProps.properties" />
Bean def for applicationProperties
<bean id="applicationProperties" class="com.*.*.ApplicationProperties">
<property name="htmlTemplate" value="${htmlTemplate}"></property>
.........................
</bean>

4. In Java code
@Autowired
private ApplicationProperties applicationProperties = null;

// get the html template and merge it with the merge objects
StringWriter htmlBody = new StringWriter();
VelocityEngineUtils.mergeTemplate(velocityEngine,
applicationProperties.getHtmlTemplate(),templateVa riablesMap, htmlBody);
