Hi,
Sounds like a config error. We see this error in Velocity when
VelocityEngine.init() was not called.
I'm no Spring expert, but Spring should be initializing Velocity for you.
Have you seen this article? It gives an example.

Best,

Hello,
I'm a french new developer.
I'm in an IBM project and new to Spring and velocity technologies.
I have to complete a web application that a person left unfinished when
leaving the project.
Unfortunately, he left me some errors :(
Velocity engine is here used to produce a document.
Here is the thing : VelocityEngine is declared in my Service
Implementation Class and initialised via xml spring files.
But the VelocityEngine declared in my class is not initialised (it remains
null (the class initialisation)).
The spring files seem OK.
In the console Debug here is what I see
Initialising the VelocityEngine via spring :
INFO org.apache.velocity.app.VelocityEngine -
**************************************************************
INFO org.apache.velocity.app.VelocityEngine - Starting Jakarta Velocity
v1.4
INFO org.apache.velocity.app.VelocityEngine - RuntimeInstance
initializing.
[...]
ERROR org.apache.velocity.app.VelocityEngine - ResourceManager : unable
to find resource 'VM_global_library.vm' in any resource loader.
Is this normal?
yes. ignore it.
[...]
Then, when trying to use the VelocityEngine I've got in
VelocityEngineUtils.mergeTemplate method I've got the following
exception (since the VelocityEngine is null):
java.lang.NullPointerException
at
org.springframework.ui.velocity.VelocityEngineUtils.mergeTemplate(VelocityEngineUtils.java:56)
Have you got any idea?
not really. i've only just recently begun learning Spring and have
not looked into their Velocity integration yet. but, it certainly
sounds like the problem is in how Spring is being used or configured.
if the VelocityEngine is initialized (as seen from the logs above),
but is then null when trying to use the VelocityEngineUtils, then it
is some problem with the setting up of VelocityEngineUtils, i'd guess.
not really a problem with Velocity.
if someone else on this list who knows more about Velocity-Spring
integration doesn't help you, then you should ask someone over on the
spring lists. they'll have a better idea of what's going on.
I can send you some code sample if it can help your understanding.
I hope you will be able to help me.
P.S : all apologies for my english.
Thanks,
Cyril ROY
