Ant构建文件，其中还包括derby数据库jar

Question

Hy,

I have an RMI, Client Server app which needs also the Derby database driver to be includes on the server side

My tree structure looks like the following:

s
│   buildcmmdc.xml
│   MyAnt.bat
│
├───lib
│       derbyclient.jar
│
└───src
    └───server
            derbyclient.jar
            ZodiacChinezesc.java
            Zodie.java
            ZodieImpl.java

My Ant build file cmmdcbuild1.xml

<project name="Server" default="Install" basedir=".">
    <description>Server actions </description>

  <property name="path" location=".."/>
  <property name="lib-dir" location="${path}/s/lib"/>
  <property name="package" value="server"/>
  <property name="interface-jar" location="${path}/i/public/classes/zodie" />
  <property name="jar-file" value="zodie.jar" />
  <property name="service-class" value="ZodieImpl"  />
  <property name="port" value="1099"/>
  <property name="hostRMIRegistry" value="localhost"/>
  <property name="hostResources" value="localhost"/>
  <property name="DERBY_HOME" location="D:/soft/db-derby-10.11.1.1-bin"/>

  <target name="Install">
    <!-- Create the time stamp -->
    <tstamp/>

  </target>

<path id="jars">
    <fileset dir="${lib-dir}"> <include name="*.jar"/> </fileset>
    <pathelement path="${DERBY_HOME}/lib/derby.jar" /> 
</path>

  <target name="Compile" depends="Init"
        description="compile the source " >
    <javac srcdir="src"

    classpathref="jars"
       includeantruntime="false"/>
    <unjar  src="public/classes/${jar-file}" dest="public/classes" />
  </target>

  <target name="Archive">
     <jar destfile="zodie.jar" basedir="public/classes">
       <include name="${package}/*"/>
       <include name="zodie/*"/>
     </jar>
  </target>

  <target name="Rmi">
     <exec executable="rmiregistry">
       <env key="classpath" value="public/classes"/>
       <arg value="${port}" />
     </exec>
  </target>

  <target name="Server">
     <java classname="${package}.${service-class}"
        classpath="${path}/s/public/classes" fork="true">  
        <jvmarg value="-Djava.rmi.server.codebase=file:${path}/s/public/classes/"/>    
        <!-- <jvmarg value="-Djava.security.policy=server.policy" />-->
        <!-- <jvmarg value="-Djava.rmi.server.hostname=guliguli" />-->
        <!--
        <jvmarg value="-Djava.rmi.server.codebase=http://${hostResources}:8080/rmi/zodie.jar" />
        -->
        <!--
        <jvmarg value="-Djava.rmi.server.codebase=ftp://${hostResources}:2121/rmi/zodie.jar" />
        -->
        <arg line="${hostRMIRegistry} ${port}"/>
     </java>
  </target> 
</project>

I see not to get the derbyclient.jar to be imported into my server side and it dosen't find my driver.

How to modify the build in order to add also the database driver.

在您的java标记中，使用classpathref属性，如下所示：

<java ..... classpathref="jars">
