Re: [FMPP] How to include java code into freemarker's data model in fmpp?

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Well, I tried to specify maven classpath and it looks like maven
classpath includes my custom code, but FMPP still can not see it.
While running maven build, ant-run prints it classpath and classes I
need to have in FMPP are included. But Freemarker instance used by
FMPP can't see them. I used Freemarker's new() modifier to create an
object, like:
<#assign AA="my.functionObject.full.ClassName"?new()>
and got build error like:
     [fmpp] Task aborted: FMPP processing session failed.
     [fmpp] Caused by: freemarker.template.TemplateException:
java.lang.ClassNotFoundException: my.functionObject.full.ClassName
     [fmpp] Caused by: java.lang.ClassNotFoundException:
my.functionObject.full.ClassName

In general, I wanted to add some custom complex logic into template
environment. This time only as custom freemarker function, but if this
strategy will work, then more logic will be possible to add.
Constructing that object in beanshell also failed with
ClassNotFoundException. It seems that FMPP freemarker instance
classpath is not the same as is passed to FMPP itself, or Maven
ant-run-plugin does not passes correct classpath. Is there any chances
that such a behaviour will be fixed in the nearest furure?

For those who interested, here is my configuration of maven ant run:
