Tomcat简介Tomcat是Apache软件基金会(Apache Software Foundation)的Jakarta 项目中的一个核心项目,由Apache、Sun和其他一些公司及个人共同开发而成。Tomcat服务器是一个免费的开放源代码的Web应用服务器,属于轻量级应用服务器,在中小型系统和并发访问用户不是很多的场合下被普遍使用,是开发和调试JSP程序的首选。Tomcat和Nginx、Apache(httpd)、lighttpd等Web服务器一样,具有处理HTML页面的功能,另外它还是一个Servlet和JSP容器,独立的Servlet容器是Tomcat的默认模式。不过,Tomcat处理静态HTML的能力不如Nginx/Apache服务器。目前Tomcat最新版本为9.0。Java容器还有resin、weblogic等。
JDK是 Java 语言的软件开发工具包,主要用于移动设备、嵌入式设备上的java应用程序。JDK是整个java开发的核心,它包含了JAVA的运行环境(JVM+Java系统类库)和JAVA工具。
DK包含了一批用于Java开发的组件,其中包括:
javac:编译器,将后缀名为.java的源代码编译成后缀名为“.class”的字节码
java:运行工具,运行.class的字节码
jar:打包工具,将相关的类文件打包成一个文件
javadoc:文档生成器,从源码注释中提取文档,注释需匹配规范
jdb debugger:调试工具
jps:显示当前java程序运行的进程状态
javap:反编译程序
appletviewer:运行和调试applet程序的工具,不需要使用浏览器
javah:从Java类生成C头文件和C源文件。这些文件提供了连接胶合,使Java和C代码可进行交互。
javaws:运行JNLP程序
extcheck:一个检测jar包冲突的工具
apt:注释处理工具
jhat:java堆分析工具
jstack:栈跟踪程序
jstat:JVM检测统计工具
jstatd:jstat守护进程
jinfo:获取正在运行或崩溃的java程序配置信息
jmap:获取java进程内存映射信息
idlj:IDL-to-Java编译器。将IDL语言转化为java文件
policytool:一个GUI的策略文件创建和管理工具
jrunscript:命令行脚本运行
