Hi,
I am trying to use Velocity templates in my project. I have a Struts
Action class that invokes a Command class which in turn invokes a Logic
class.
The job of the Logic class is to handle the main logic of the
functionality or use case.
I have designed Util classes that need to make use of Velocity templates
to generate required data.
I have added the following to the web deployment descriptor (web.xml)
file.
...
<servlet>
<servlet-name>velocity</servlet-name>
<servlet-class>org.apache.velocity.tools.view.servlet.VelocityViewServle
t</servlet-class>
<init-param>
<param-name>org.apache.velocity.properties</param-name>
<param-value>/WEB-INF/velocity.properties</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
...
<servlet-mapping>
<servlet-name>velocity</servlet-name>
<url-pattern>*.vm</url-pattern>
</servlet-mapping>
...
The velocity.properties file has the below given contents
resource.loader=file
file.resource.loader.class=org.apache.velocity.runtime.resource.loader.F
ileResourceLoader
file.resource.loader.path=/WEB-INF/templates/
file.resource.loader.cache=false
file.resource.loader.modificationCheckInterval=0
velocimacro.library = /WEB-INF/VM_global_library.vm
velocimacro.permissions.allow.inline = true
velocimacro.permissions.allow.inline.to.replace.global = false
velocimacro.permissions.allow.inline.local.scope = false
velocimacro.context.localscope = false
Whenever I start the server, I get the following error messages with a
whole load of stack traces.
[12/30/08 13:14:18:105 IST] 744f744f WebGroup I SRVE0180I: [supWeb]
[/sup] [Servlet.LOG]: Velocity [error] ResourceManager : unable to
find resource '/WEB-INF/VM_global_library.vm' in any resource loader.
[12/30/08 13:14:18:120 IST] 744f744f WebGroup I SRVE0180I: [supWeb]
[/sup] [Servlet.LOG]: Velocity [error] Velocimacro : Velocimacro :
Error using VM library : /WEB-INF/VM_global_library.vm
[12/30/08 13:14:18:167 IST] 744f744f WebGroup I SRVE0180I: [supWeb]
[/sup] [Servlet.LOG]: Velocity [error]
org.apache.velocity.exception.ResourceNotFoundException: Unable to find
resource '/WEB-INF/VM_global_library.vm'
But the server starts successfully. Now when the Util class is invoked.
It makes a call to the getTemplate() method of Velocity class.
And this time too I get a ResourceNotFoundException with the message
"Unable to find resource abcd.vm
The code written, in the Util class, for getting the templates is as
follows:
StringWriter sw = new StringWriter();
String path="/ABCD/abcd";
VelocityContext ctx = null;
try {
Velocity.init();
ctx = new VelocityContext();
template = Velocity.getTemplate("abcd.vm");
ctx.put("path", path);
template.merge(ctx, sw);
System.out.println(sw);
} catch (Exception ex) {
System.out.println(ex);
ex.printStackTrace();
}
I get a ResourceNotFoundException at line Velocity.getTemplate().
The template files have been placed in /WEB-INF/templates folder.
I am using Websphere 5.1 as application server.
