hi simon,
i just tried to introduce the same 'errors' you did and my
pre-compiling stopped and complained the following exception:
[jasperc] 2004-06-30 10:38:20 - ERROR-the file '\jsp\Test.jsp'
generated the following general exception: java.
lang.NullPointerException
[jasperc] at org.apache.jasper.JspC.processFile(JspC.java:596)
[jasperc] at org.apache.jasper.JspC.execute(JspC.java:801)
[jasperc] at org.apache.jasper.JspC.main(JspC.java:823)
so it seems i'm getting the error-checking that you want. the
difference is that i didn't use <taskdef> to do my pre-compiling. i
just used ant's <jspc> task:
<jspc srcdir="${webapp.build}" destdir="gensrc/src"
uriroot="${webapp.build}"
compiler="jasper41"
includes="index.jsp,jsp/**/*.jsp"
verbose="9"
webxml="jspmaps">
<classpath>
<pathelement path="${tomcat.home}/common/lib/jasper-compiler.jar"/>
<pathelement path="${tomcat.home}/common/lib/servlet.jar"/>
<pathelement path="${tomcat.home}/common/lib/jasper-runtime.jar"/>
<pathelement path="${ant.home}/lib/ant.jar"/>
</classpath>
</jspc>
why do you need to define your own pre-compile task may i ask?
