Freemarker does not find template on classpath

[trumml]

Using JBoss 7.1.1-FINAL freemarker does not find its libraries via class path (worked perfectly well on version 5) - same error happens on EAP 6.1...

We have several WAR files deployed to the application server and one of those WARs contain a JAR which hosts the template files in META-INF/templates/packages/file.ftl

Configuration of Freemarker:

setTemplateLoaderPath("classpath:/META-INF/templates/com.cg.g3his.med/");

Stack:

Caused by: java.lang.IllegalStateException: java.io.FileNotFoundException: Template MedicationOrderSummary.ftl not found.

What I've noticed so far is that in the virtual file system I do see following path "jboss-as-7.1.1.Final\standalone\tmp\vfs\deployment220be65c1a50976\med-medication-impl-3.1.0-SNAPSHOT.jar-38da8efa22b6bf25\contents\META-INF\templates\com.cg.g3his.med" but it does not contain any template file.

This code is not trying to access the template on the classpath. It's trying to read it from the file system.

What does the code in com.cg.g3his.med.freemarker.FreemarkerTemplateProcessor.process look like?

An educated guess tells me that you have used something like java.lang.ClassLoader#getResource(java.lang.String) to get a reference to the resource and then assumed that it is a file in the file system.

You need to use java.lang.ClassLoader#getResourceAsStream(java.lang.String) instead if you can.

Hi Guys,

I have the same issue. It used to work on jboss-4.2.2.GA but not on jboss-6.1.0.Final

We have the configuration set to load like below from the classpath. But when I remote Debug like Stephen Coy said, it seems to read from specific File Location:

opt/jboss/server/default/tmp/vfs/automount936ffc708120d59e/libname.jar-844c33b51426ffc5/contents/fraud/accertifyUserProfile.ftl

The accertifyUserProfile.ftl is not exploded or extracted in the above directory by jboss. The accertifyUserProfile.ftl file is there in libname.jar under the fraud directory (inside the zip). When jboss starts up, it copies the jar in the above location under tmp/vfs and creates a contents/fraud directory which is empty.

  <bean id="freemarkerConfiguration" class="org.springframework.ui.freemarker.FreeMarkerConfigurationFactoryBean">

                    <description>Using the Config directly so we can use it outside the web tier</description>

  <property name="templateLoaderPaths">

  <list>

                                        <value>classpath:fraud</value>

  </list>

  </property>

Sri,

In your case you appear to be using a version of the Spring Framework that is incompatible with JBossAS/WildFly. You must use version 3.0.3 or newer.

Hi Stephen and Martin,

The suggestion here worked for me:

Thanks for your inputs!

Well - the default TemplateLoader from Freemarker is the FileTemplateLoader.

Changing this to the SpringTemplateLoader worked for me...
