Thanks for your replay!
I've check out the trunk and did some tests and it works fine. I
tested for one VelocityEngine. But in my webapp I need a
VelocityEngine for each user, because each user has its own set of
templates. What's the preffered way to do this?
Do I need a class per user, that extends StringResourceRepositoryImpl,
velocityEngine.setApplicationAttribute("foo", repo)?
My next problem is: I have a set of velocity macros. Add the macros in
the same way like templates has no effect! How can I do this?
Thanks a lot for your help!

Thilo

it's described here:
http://velocity.apache.org/engine/releases/velocity-1.5/apidocs/org/apache/velocity/runtime/resource/loader/StringResourceLoader.html
so you would do something like the following once you initialized your
VelocityEngine:
StringResourceRepository vsRepository = StringResourceLoader.getRepository();
String myTemplateName = "/somewhere/intherepo/name";
String myTemplateBody = "Hi, ${username}... this is a some template!";
vsRepository.putStringResource(myTemplateName, myTemplateBody);
but be wary, since the repository is unfortunately a singleton in
Velocity 1.5, you can only initialize one VelocityEngine using the
StringResourceLoader. if you try and initialize another
VelocityEngine configured to use the StringResourceLoader, you will
get an IllegalStateException. :( Also, the VelocityEngine using it
must be initialized before you try to retrieve the repository. :(
I've improved things greatly for the next version of Velocity. If you
are willing to checkout and build the trunk, you can use it as
described here:
http://velocity.apache.org/engine/devel/apidocs/org/apache/velocity/runtime/resource/loader/StringResourceLoader.html
