jspc NullPointerException
I am trying the JspC with ANT 1.5 beta 3. Some feedback, then the latest
problem.
1) I downloaded Tomcat 4.0.4 'cos that seemed best version '4' given the
comment in the jspc page:
By default the task uses the Jasper JSP compiler. This means the task needs
jasper.jar and jasper-runtime.jar, which come with builds of Tomcat
4/Catalina from the Jakarta Tomcat project
<http://jakarta.apache.org/tomcat/>
1.1) Nothing in the "Library Dependencies" seems to mention Tomcat, let
along versions.
1.2) I could find a jasper-runtime.jar but not jasper.jar. I eventually
added jasper-compiler.jar.
2) I was hoping for some consistency w/ <javac> so I copied that to start. I
failed to give an internal <include> and the task crashed with NullPointer
exception in the file scanning area.
3) I shouldn't waste folks time on the fast I tried <JspC not <jspc and it
didn't work, 'cos I guess most Ant folks know better than use the task
"title" as the name, just not me...
4) Things started to work, sorta.
<jspc
srcdir="${src}"
destdir="${build}/${openbiz.part}"
package="com.openbiz.jsp"
verbose="9"
classpathref="project.class.path"
>
<include name="**/*.jsp" />
</jspc>
and got.

Could this be 'cos my pages use taglibs? [I am not sure which one it is
trying, so I can't hack it out.]
I tried adding a uriroot, but same result.
Thanks in advance for any help.

For this test I am using some JSPs with no TagLibs, and only one
jsp:include. Heck, I even just took that out, and got the same result. I
removed WEB-INF and same result. I removed all JSP .. it worked :-) -- but
did nothing. I emptied my JSP -- empty file, it crashed same as before.
Off into wild guessing, but could it be my environment? My various versions
of classes (I have a bucket-o-load of Jakata software, thanks all, so
perhaps version mismatches?) I am wondering perhaps XML -- since I have
crimson and xerces and all. I've tried to limit my classpath to the bare
essentials, namely:
..... oops, ant -debug is telling me it is removing things from the
classpath 'cos they do not exist. [Gosh, I wish this useful error, ok --
debatably warning, came out other than jsut in debug]
It seems ANT 5 beta 3 is using xerces not crimson, I need to add that in
there. I also see my compile-time classpath is getting put before the system
env classpath (my choice) before jspc is launched, I need to change that...
... and it is working. Darn, not quite...
Now I get (per file, which is better I guess):
[echo] SRC : .
[echo] DEST : F:/java/build/webadmin
[echo] URIROOT : .

The directory exists, and I do see a created directory:

any thoughts? Clearly it seems like I have a better (hopefully right)
classpath for running Jasper, but now it seems the outputfile is somehow
making it sick. I've move it onto the same disk, I've moved it to the same
directory as source.

That should work. i say should, because it clearly doesnt.
One thing I will have to look at is classpath handling. You do not need TLD
implementations on the classpath, just the .tld files in /webinf or whatever
off uriroot.

Steve,

I tried adding webinf="${src}/WEB-INF" (and I tried web-inf) and got
"attribute not supported by jspc", so .... I (now) assume you were saying
they are parameters of the commandline JSPC. FWIIW: The command line JSPC

The only change to it from the first posting I made was the addition of the
uriroot attribute, but that was 'cos command line JSPC taught me I needed it
for some includes. At time of execution those properties are ${src}=.
${build}=F:/java/biuld ${openbiz.part}=webadmin, and project.class.path is

The WEB-INF directory is below here.

there is a webinf param that should point to where web-inf lives, though
jasper should work it out for itself.
can you post your <jspc> declaration?

Thanks Steve, I have tried with 4.1.3, with the same result.
Reading the stack trace (below) I see processWebDotXml -- which I assume
means it is trying to process a WEB-INF\web.xml, which I didn't have in the
first tree of JSPs I was working with, but even when I extract a WAR into my
directory, and I have this file, I get the same exception.
I tried JSPC from the command line, with theoretically the same parameters,
and it works.
Is there some aspect of the ANT task attemptign to deal with web.xml that I
need to configure?

Taglibs have worked on jspc. Try getting a 4.1 drop instead, as that is
probably the best there is.
