Spring 3.x + ant 1.7.x Build problem

[Pranav Nakate]

Hi,

I created a Spring project and it runs fine when i create a WAR using Eclipse built-in service for doing so...deploys properly and everything...

i wrote an Ant build file [ build.xml ] to build this project...i deployed it on the same Apache Tomcat server...with this
the home page opens correctly...but whenever a request is hit, the application crashes...

below is my build xml ...

<project name="ABC" default="WAR" basedir=".">

<!--	<property name="build" value="build" /> -->
	<property name="appname" value="ABC" />
<!--	<property name="tomcatAppDir" value="E:\Software\apache-tomcat-6.0.28\webapps" /> -->
	<property file="build.properties" />
	
	<path id="classpath">
		<fileset dir="${basedir}/WebContent/WEB-INF/lib">
			<include name="**/*.jar" />
		</fileset>
		<pathelement location="${tomcatHome}/lib"/>
		<fileset dir="${tomcatHome}/lib">
			<include name="**/*.jar" />
		</fileset>
	</path>
	
	<target name="deletePrevBuild">
		<echo>Deleting Previous Build</echo>
		<delete dir="${basedir}/${build}" />
		<echo>${tomcatHome}</echo>
	</target>

	<target name="makeBuildDir" depends="deletePrevBuild">
			<echo>Creating new Build Folder</echo>
			<mkdir dir="${basedir}/${build}" />
			<mkdir dir="${basedir}/${build}/classes" />
	</target>
	
	<target name="compile" depends="makeBuildDir">
		<javac srcdir="${basedir}/src" destdir="${basedir}/${build}/classes" classpathref="classpath" />
		<copy file="${basedir}/src/log4j.properties" tofile="${basedir}/${build}/classes/log4j.properties" />
	</target>
	
	<target name="WAR">
		<antcall target="compile" />
		<war destfile="${basedir}/${build}/${appname}.war" webxml="${basedir}/WebContent/WEB-INF/web.xml">
		
			<fileset dir="${basedir}/WebContent">
				<include name="**/*.*"/>
			</fileset>
			<classes dir="${basedir}/${build}/classes" />

			<lib dir="${basedir}/WebContent/WEB-INF/lib" />
		</war>	
		<copy file="${basedir}/${build}/${appname}.war" todir="${tomcatHome}/webapps" overwrite="true" />
	</target>

</project>

below is the error i get...

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.IllegalArgumentException: Name for argument type [java.lang.String] not available, and parameter name information not found in class file either.

Please tell me what i am missing...

seems that i am missing some configuration in build.xml, which is causing some classpath mismatch with tomcat

Not directly answering your question here is but is there a reason you are set on ANT? Spring projects are much easier to build with Maven and there are tons of examples out there showing how to do this.

[Pranav Nakate]

makes sense...

moving to Maven!

Thanks for the quick reply Bill!
