Configuring Chenillekit-template with tapestry
Hello, I think I've configured chenillekit-template with my tapestry project
as followed.
<dependency>
<groupId>org.chenillekit</groupId>
<artifactId>chenillekit-template</artifactId>
<version>1.3.3</version>
</dependency>
public static void contributeVelocityService(MappedConfiguration<String,
Resource> configuration) {
Resource velocityConfig = new
ClasspathResource("/velocity.properties");
configuration.add("velocity.configuration", velocityConfig);
}
However I'm getting the following exception while trying to use it, but
can't seem to figure out if it's something I'm doing with my project or a
chenillekit issue. I'm using tapestry 5.3.6

Re: Configuring Chenillekit-template with tapestry
Posted by George Christman <gc...@cardaddy.com>.
I was unable to get Velocity to work, however I switched to FreeMarker and
was able to get things to work with the following configuration. This should
provide an example to anybody else who may encounter issues similar to the
ones I had.
pom.xml
<dependency>
<groupId>org.freemarker</groupId>
<artifactId>freemarker</artifactId>
<version>2.3.19</version>
</dependency>
<dependency>
<groupId>org.chenillekit</groupId>
<artifactId>chenillekit-template</artifactId>
<version>1.3.3</version>
</dependency>
AppModule
/*
* FreeMarker Services
*/
public static void
contributeFreeMarkerService(MappedConfiguration<String,
freemarker.template.Configuration> configuration) {
freemarker.template.Configuration fmConfiguration = new
freemarker.template.Configuration();
fmConfiguration.setWhitespaceStripping(false);
fmConfiguration.setClassForTemplateLoading(fmConfiguration.getClass(), "/");
configuration.add("freemarker.configuration", fmConfiguration);
}
FreeMarkerServiceImpl
private final PageRenderLinkSource pageRenderLinkSource;
private final TemplateService templateService;
public FreeMarkerServiceImpl(@FreeMarker TemplateService
templateService, PageRenderLinkSource pageRenderLinkSource) {
this.templateService = templateService;
this.pageRenderLinkSource = pageRenderLinkSource;
}
public String emailBodyTemplate(String template, YourObject obj) {
String pr_url =
this.pageRenderLinkSource.createPageRenderLinkWithContext(YourObject.class,
obj.getId()).toAbsoluteURI();
InputStream input = new ByteArrayInputStream(template.getBytes());
OutputStream output = new ByteArrayOutputStream();
Map parameterMap = new HashMap();
parameterMap.put("obj_number", obj.getobjNumber());
parameterMap.put("obj_url", obj_url);
templateService.mergeDataWithStream(input, output, parameterMap);
return output.toString();
}
