This article mainly refer to this blog http://jackycheng2007.iteye.com/blog/1477845, but the whole process encountered another problem, the special record as follows
1. Get Source code

Way one: from the official website http://tomcat.apache.org/download-70.cgi direct download, the official website provides binary and source code two kinds of downloading way, want to study tomcat source code, select source Codes way to download

Mode two: Use SVN to get the source code, first install SVN, then create a new directory TOMCAT7, and then execute the following command in the directory

[Java] view plain copy SVN co http://svn.apache.org/repos/asf/tomcat/tc7.0.x/tags/TOMCAT_7_0_35/./tags Recorded a different version of the Tomcat source, here is the download version is 7.0.35

2. Import the source code into EclipseTomcat's source code is created and managed using Ant. Install Ant and then execute Ant ide-eclipse, which will be produced in the TOMCAT7 directory after successful execution. Project and. Classpath two files, which became Eclipse Engineering.      So you can import the Tomcat source into eclipse. Execute Ant ide-eclipse times wrong:[Java]View plain Copy build FAILED build.xml:2361:the following error occurred while executing this line:build FAILED build . Xml:2449:compile failed;   The compiler error output for details. To view the compiled error log:[Java]  View Plain  copy  build-tomcat-dbcp:        [copy] copying  64 files to E:\usr\share\java\tomcat7-deps\dbcp         [Move] moving 64 files to e:\usr\share\java\tomcat7-deps\dbcp\src\java\org\apache\ tomcat\dbcp       [javac] compiling 64 source files to  E:\usr\share\java\tomcat7-deps\dbcp\classes       [javac] warning:  [options] bootstrap class path not set in conjunction with  -source 1.6       [javac] e:\usr\share\java\tomcat7-deps\dbcp\src\java\ org\apache\tomcat\dbcp\dbcp\basicdatasource.java:53: error: bas   IcDataSource is  not abstract and does not override abstract method  Getparentlogger ()  IN&NBsp commondatasource       [javac] public class BasicDataSource  implements datasource {       [javac]         ^       [javac] e:\usr\share\java\tomcat7-deps\dbcp\src\ java\org\apache\tomcat\dbcp\dbcp\delegatingstatement.java:46: error:    DelegatingStatement  is not abstract and does not override abstract method  Iscloseoncompletion ()  in Statement       [javac] public class  DelegatingStatement extends AbandonedTrace implements Statement {       [javac]        ^        [javac] e:\usr\share\java\tomcat7-deps\dbcp\src\java\org\apache\tomcat\dbcp\dbcp\ Delegatingpreparedstatement.java:57  : error: delegatingpreparedstatement is not abstract and  Does not override abstract method iscloseoncompletion ()  in Stat   ement   based on log errors, the dependent DBCP associated jar version is incorrect. The version of JDK installed on this machine is 1.7, and then a 1.6 jdk is installed on this machine, and the related environment variables are modified so that java_home points to the JDK 1.6 directory. Execute ant ide-eclipse again  build successful
Total Time:2 minutes seconds
Also note that the build log update for BUILD-TOMCAT-DBCP is:[Java]  View Plain  copy build-tomcat-dbcp:        [copy] Copying  64 files to e:\usr\share\java\tomcat7-deps\dbcp        [move]  moving 64 files to e:\usr\share\java\tomcat7-deps\dbcp\src\java\org\apache\tomcat\ dbcp       [javac] compiling 64 source files to e:\ usr\share\java\tomcat7-deps\dbcp\classes       [javac]  Note: Some input files are used or overwritten with obsolete  api.        [javac]  Note: For more information, please use  -Xlint:deprecation  recompile.        [javac]  Note: Some input files use an unchecked or unsafe operation.        [javac]  Note: For more information, please use  -Xlint:unchecked  recompile.          [jar] building jar: e:\usr\share\java\ tomcat7-deps\dbcp\tomcat-dbcp.jar         [jar] building jar: e:\usr\share\java\tomcat7-deps\dbcp\tomcat-dbcp-src.jar    Therefore, the problem can be summed up as follows: The JDK version of the Tomcat source dependency is 1.6 and below, and using jdk1.7 can cause the build to fail.
