in org.apache.taglibs.standard.tag.el.xml.ParamTag private void evaluateExpressions() throws JspException { name = (String) ExpressionUtil.evalNotNull( "import", "name", name_, String.class, this, pageContext); value = ExpressionUtil.evalNotNull( "import", "value", value_, Object.class, this, pageContext); I believe "import" should be "param". otherwise the error message comes out saying the import tag.. which provoked a lot of confused staring at the c:import statement :-)
Fixed - thanks.
