hmm. no, this isn't the NPE mentioned in the FAQ. i think you've run afoul of a bug that was fixed, unfixed, and refixed.
Fixed: http://svn.apache.org/viewcvs.cgi/jakarta/velocity/trunk/src/java/org/apache/velocity/io/VelocityWriter.java?rev=75937&r1=75805&r2=75937 Unfixed: http://svn.apache.org/viewcvs.cgi/jakarta/velocity/trunk/src/java/org/apache/velocity/io/VelocityWriter.java?rev=75959&r1=75949&r2=75959 Refixed: http://svn.apache.org/viewcvs.cgi/jakarta/velocity/trunk/src/java/org/apache/velocity/io/VelocityWriter.java?rev=75960&r1=75959&r2=75960 unfortunately, it appears that Velocity 1.4 was released after the "unfixed" revision and before the refixed revision, since the problem occurs on line 319 in both the 1.4 tag and the unfixed revision on the trunk. :( so, all i can recommend is that you check out the last SVN code for Velocity 1.5 and use that. hopefully we'll get it released soon, but in the meantime, it is quite stable and definitely superior to the 1.4 version. if you are unable to build it yourself, let me know and i will upload a nightly build that you can use.
