jspc precompiler error

hi,

i have a difficult problem with precompiling jsp with
jspc-maven-plugin 
(v1.4.6)

i get this error:
[INFO] [jspc:compile {execution: jspc}]
java.lang.NumberFormatException: For input string:
"$" 
java.lang.NumberFormatException.forInputString(NumberFormatE
xception.java:48)
        at java.lang.Integer.parseInt(Integer.java:447)
        at java.lang.Integer.valueOf(Integer.java:553)
[...]


this is my jspc pom snippet

			<plugin>
				<groupId>org.codehaus.mojo</groupId>
				<artifactId>jspc-maven-plugin</artifactId>
				<configuration>
					<source>1.5</source>
					<target>1.5</target>
					<javaEncoding>UTF-8</javaEncoding>
				</configuration>
				<executions>
					<execution>
						<id>jspc</id>
						<goals>
							<goal>compile</goal>
						</goals>
					</execution>
				</executions>
			</plugin>
  [...]
		<dependency>
			<groupId>javax.servlet</groupId>
			<artifactId>servlet-api</artifactId>
			<version>2.5</version>
		</dependency>
		<dependency>
			<groupId>javax.servlet</groupId>
			<artifactId>jstl</artifactId>
			<version>1.1.2</version>
		</dependency>
		<dependency>
			<groupId>taglibs</groupId>
			<artifactId>standard</artifactId>
			<version>1.1.2</version>
		</dependency>

this is my jsp file

<?xml version="1.0" encoding="UTF-8"
?>
<jsp:root xmlns="http://www.w3.org/
1999/xhtml"
	xmlns:jsp="http://java.sun.co
m/JSP/Page"
	xmlns:c="http://java.s
un.com/jsp/jstl/core" version="2.0">

	<jsp:directive.page
contentType="text/html;charset=utf-8" />

	<c:forEach var="i" begin="1"
end="$">
		<c:out value="$" />
	</c:forEach>

</jsp:root>

To track down the error i created a second project with this
pom.xml 
(complete) and just this jsp file in src/main/webapp and a
minimal web.xml 
and everything works even without 

<?xml version="1.0"
encoding="UTF-8"?>
<project>
	<modelVersion>4.0.0</modelVersion>
	<groupId>jspc</groupId>
	<artifactId>jspc</artifactId>
	<packaging>war</packaging>
	<version>0.0.1</version>
	<description></description>
	<build>
		<plugins>
			<plugin>
				<groupId>org.codehaus.mojo</groupId>
				<artifactId>jspc-maven-plugin</artifactId>
				<executions>
					<execution>
						<id>jspc</id>
						<goals>
							<goal>compile</goal>
						</goals>
					</execution>
				</executions>
			</plugin>
		</plugins>
	</build>
</project>

if i add dependencies to this pom it doesnt work anymore:

	<dependencies>
		<dependency>
			<groupId>javax.servlet</groupId>
			<artifactId>servlet-api</artifactId>
			<version>2.5</version>
		</dependency>
		<dependency>
			<groupId>javax.servlet</groupId>
			<artifactId>jstl</artifactId>
			<version>1.1.2</version>
		</dependency>
		<dependency>
			<groupId>taglibs</groupId>
			<artifactId>standard</artifactId>
			<version>1.1.2</version>
		</dependency>
	</dependencies>

i guess my understanding of jspc is entirly wrong. Can
someone help me 
explaining what went wrong and how to fix it?

kind regards,
janning

I'm not sure about the solution to your problem, but you may
want to try 
using the Jetty jspc plugin, rather than the Codehaus
one...

Hi


You must use the jspc plugin in conjunction with the
maven-war-plugin. The
maven-war-plugin must have its *webXml* configuration
parameter set to the
newly created web.xml, which is $basedir/target/jspweb.xml
by default. See
the following example configuration in the link :

http://mojo.codehaus.org/jspc-maven-plugin/usage.html

Also try to add the following dependencies to your POM:
       <dependency>
             <groupId>javax.servlet</groupId>
             <artifactId>jsp-api</artifactId>
             <version>2.0</version>
         </dependency>


Thanks
