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).

August 2005 23:58 An: tomcat-user@jakarta.apache.org 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. - Richard Exception from running "ant compile": Loaded from C:\jakarta-tomcat-5.5.10-deployer\lib\jasper-compiler.jar org/apache/jasper/compiler/AntCompiler.class
