AW: JspC compile exception in tomcat-deployer 5.5.10
Hi Richard,
the problem is that your classpath for the jasper path is not correct.
So this Null Pointer exception actually means that some class was not found.
Note that you need all the tomcat libraries in your jaser classpath, as well
as your libs as well.
I post you my script, which is working Ok (on Tomcat 5.5.7).
Cheers
Bernhard

Betreff: JspC compile exception in tomcat-deployer 5.5.10
Hello,
I am using the jakarta-tomcat-5.5.10-deployer to deploy my customized war
file to tomcat. When I have it do the compile target so it pre-compiles
the JSP's I get the exception below (its sort of long). I've got the source
and can see that it is happening as it processes the JSPs. But it gives no
clue as to which JSP is causing the problem.
Is there a way to turn on a trace that would list each file as it is
processed? I've also looked in the output directory - but there are not
class files at all. And the generated_web.xml is completely empty at this
point.
Here is how I've got the jasper2 task defined in my build.xml:
jasper2 validateXml=false
uriroot=${webapp.path}
webXmlFragment=${webapp.path}/WEB-INF/generated_web.xml
addWebXmlMappings=true
outputDir=${webapp.path}/WEB-INF/classes /
Notice that I turned validateXml to false - otherwise I get the following
message:
[jasper2] org.xml.sax.SAXParseException: Document is invalid: no grammar
found.
I have compared and compared my web.xml to the spec and it seems to be OK.
It complains about position 9 in the 3rd line. Line 3 follows, position 9 is
the start of the xmlns= attribute:
web-app xmlns=http://java.sun.com/xml/ns/j2ee;
xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance;
xsi:schemaLocation=http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd;
version=2.4
... which appears to be fine.
Any ideas or help is appreciated. I have tried this a few months back in
5.5.7 but got the same results (worked fine in 5.0.19). I imagine its a
problem either in one of my JSPs or in the web.xml - but cannot figure it
out.
Thanks in advance for any ideas.
