Thanks Wendell, You are right! FOP NullPointerException errors are extremely unhelpful. I did try to create the xml page using the command line parser. This time it complained about that the xml file not being well-formed, even though the .fo file is. Not sure how that can happen. If I would remove the code below then every thing is fine. Does it make any sense to you? <xsl:template match="node()"> <xsl:copy> <xsl:copy-of select="@*"/> <xsl:if test="contains(. ,'<sub>')"> <fo:inline baseline-shift="super" font-size=".75em"> <xsl:text>FOUND SUPER </xsl:text> </fo:inline> </xsl:if> </xsl:copy> </xsl:template> Norm Wendell Piez <wapiez@xxxxxxxxxxxxxxxx> wrote: >I've seen the NullPointerException as an (extremely unhelpful) error >message when running FOP end-to-end (straight from input XML through to >PDF) and there's either a parse error or a stylesheet runtime error.
