Chapter 1
在Netbeans里面新建一个Java project, 然后把Jetty 6的源码加进来，添加一些必要的依赖包，添加ant脚本，开启调试。1. 新建一个Java project, 加入Jetty 6 source package
你可以从这个url拿到源码包:
http://dist.codehaus.org/jetty/jetty-6.1.26/jetty-6.1.26-src.zip
2. 添加依赖包：
servlet-api-2.5-20081211.jar
slf4j-api-1.3.1.jar
以上这些是compile jetty时必须的包
3. 添加配置文件或属性:
etc/jetty.xml
etc/webdefault.xml
realm.properties
4. 配置Netbeans脚本:
<project xmlns="http://www.netbeans.org/ns/project/1"> <type>org.netbeans.modules.ant.freeform</type> <configuration> <!-- Either of the below two is applicable --> <!--<general-data xmlns="http://www.netbeans.org/ns/freeform-project/1">--> <general-data xmlns="http://www.netbeans.org/ns/freeform-project/2"> <name>jetty</name> <properties> <property name="ant.script">nbproject/targets.xml</property> <property name="jetty.script">build/jetty-build.xml</property> </properties> <folders> <source-folder> <label>jetty</label> <location>.</location> <encoding>windows-1252</encoding> </source-folder> <source-folder> <label>Java Sources</label> <type>java</type> <location>src</location> <encoding>windows-1252</encoding> </source-folder> </folders> <ide-actions> <action name="build"> <script>${jetty.script}</script> <target>nbbuild</target> </action> <action name="clean"> <script>${jetty.script}</script> <target>clean</target> </action> <action name="run"> <script>${jetty.script}</script> <target>nbrun</target> </action> <action name="debug"> <script>${jetty.script}</script> <target>nbdebug</target> </action> </ide-actions> <view> <items> <source-folder style="tree"> <label>Web folder</label> <location>webapps</location> </source-folder> <source-folder style="tree"> <label>Jetty configs</label> <location>webapps/WEB-INF/etc</location> </source-folder> <source-folder style="packages"> <label>Java src</label> <location>src</location> </source-folder> </items> <context-menu> <ide-action name="build"/> <ide-action name="clean"/> <ide-action name="javadoc"/> <ide-action name="run"/> <ide-action name="test"/> <ide-action name="debug"/> </context-menu> </view> </general-data> <java-data xmlns="http://www.netbeans.org/ns/freeform-project-java/3"> <compilation-unit> <package-root>src</package-root> <classpath mode="compile"></classpath> <built-to>classes</built-to> <javadoc-built-to>doc</javadoc-built-to> <source-level>1.6</source-level> </compilation-unit> </java-data> </configuration></project>
3. 添加jetty脚本
每次compile时候，会根据更改情况，生成新的classes。这些classes会被jar(update)到jetty-6.1.26.jar，然后启动IDE的debugger，然后启动jetty6,并把jetty6附加到debugger上，这样就可以调试track代码的运行
a. build脚本
javac.source=1.6
javac.target=1.6
JAVAC_EXE=
srcDir=source directory
outDir=output directory
<target name="nbbuild" depends="configProperties"> <javac source="${javac.source}" target="${javac.target}" executable="${JAVAC_EXE}" fork="yes" destdir="${outDir}" classpath="${outDir}" classpathref="libraries" optimize="off" verbose="off" debug="on" memoryInitialSize="512M" memoryMaximumSize="768M"> <src path="${srcDir}"/> <include name="**/*.java"/> </javac> <jar update="true" compress="true" jarfile="${jettyOutDir}\\lib\\jetty-6.1.26.jar"> <manifest> <attribute name="Build-Date" value="${build.time}"/> <attribute name="Build-User" value="${user.name}"/> <attribute name="Build-File" value="${ant.file}"/> <attribute name="Build-Location" value="${prefix}"/> <attribute name="Build-Platform" value="${os.name} ${os.version}(${os.arch})"/> <attribute name="Specification-Title" value="${java.specification.name}"/> <attribute name="Specification-Vendor" value="${java.vendor}"/> <attribute name="Specification-Version" value="${java.version}"/> <attribute name="CopyrightNotice" value="Copyright (c) 2012-${build.year} ${corp.name}"/> <attribute name="Implementation-Title" value="${ant.project.name} - HTTPS Handler"/> <attribute name="Implementation-Vendor" value="${corp.name}"/> <attribute name="Implementation-Version" value="${build.version}"/> </manifest> <fileset dir="${outDir}"> <include name="org/mortbay/**/*.class"/> </fileset> </jar> </target>
b. debug脚本
<target name="nbdebug" depends="nbbuild"> <!-- Copy the necessary configuration files and libraries to the jetty output direction --> <copy todir="${jettyOutDir}" file="jetty/start.jar" overwrite="no"/> <copy todir="${jettyOutDir}/etc" overwrite="no"> <fileset dir="jetty/etc"> <include name="jetty.xml"/> <include name="webdefault.xml"/> <include name="configure.dtd"/> <include name="realm.properties"/> </fileset> </copy> <copy todir="${jettyOutDir}/lib" overwrite="no"> <fileset dir="lib"> <include name="**/*.jar"/> </fileset> </copy> <copy todir="${jettyOutDir}/ext" overwrite="no"> <fileset dir="jetty/ext"> <include name="*.jar"/> </fileset> </copy> <mkdir dir="${jettyOutDir}/lib"/> <mkdir dir="${jettyOutDir}/bin/logs"/> <copy todir="${jettyOutDir}/webapps" overwrite="no"> <fileset dir="webapps"> <include name="**/*"/> </fileset> </copy> <!-- Start the debugger --> <nbjpdastart name="Jetty 6" addressproperty="jpda.address2" transport="dt_socket"> <sourcepath> <pathelement path="${srcDir}"/> </sourcepath> </nbjpdastart> <!-- Start the application --> <java jar="${jettyOutDir}\\start.jar" fork="yes" dir="${jettyOutDir}\\bin" failonerror="true" classpathref="libraries" jvm="${java.executable}"> <jvmarg value="-Xdebug"/> <jvmarg value="-mx256M"/> <jvmarg value="-Xnoagent"/> <jvmarg value="-Djetty.home=."/> <jvmarg value="-Djava.compiler=none"/> <jvmarg value="-Xrunjdwp:transport=dt_socket,address=${jpda.address2}"/> <jvmarg value="-DSTOP.PORT=-1"/> <jvmarg value="-Xverify:none"/> <jvmarg value="-Xbootclasspath/a:${jettyOutDir}\\ext\\mail.jar"/> <jvmarg value="-Dprimary.address=10.158.171.103"/> <jvmarg value="-Dprimary.port=8080"/> </java> </target>
4. 点击debug，可以看到output panel上有输出，debug toolbar也会出现。在jetty代码里加个断点，就可以调试了。
