Recipe 1.3 Compiling a Servlet
Tomcat 5 supports the servlet API 2.4; the JAR file that you need on the classpath is located at <Tomcat-5-installation-directory>/common/lib/servlet-api.jar. Tomcat 4.1.24 uses the servlet 2.3 API. The servlet classes are located at: <Tomcat-4-installation-directory>/common/lib/servlet.jar.
For BEA WebLogic 7.0, the servlet classes and many other subpackages of the javax package (e.g., javax.ejb, javax.mail, javax.sql) are located at: <WebLogic-installation-directory>/weblogic700/server/lib/weblogic.jar.
javac -classpath K:\tomcat5\jakarta-tomcat-5\dist\common\lib\servlet-api.jar -d ./build ./src/FirstServlet.java
For this command line to run successfully, you must change to the parent directory of the src directory.
If the servlet depends on any other libraries, you have to include those JAR files on your classpath as well. I have included only the servlet-api.jar JAR file in this command line.
You also have to substitute the directory path for your own installation of Tomcat for this line of the prior command-line sequence:
This command line uses the built-in javac compiler that comes with the Sun Microsystems Java Software Development Kit (JDK). For this command to work properly, you have to include the location of the Java SDK that you are using in the PATH environment variable. For example, on a Unix-based Mac OS X 10.2 system, the directory path /usr/bin must be included in the PATH variable. On my Windows NT machine, the PATH includes h:\j2sdk1.4.1_01\bin.
