[Go] Tip error package javax.servlet.jsp does not exist package Javax.servletr.jsp.tagext does not exist

You did not configure the Servlet-api.jar,tools.jar,rt.jar,jsp-api.jar classpath when you ran the Java servlet container

My classpath=.
.; %java_home%\jre\lib\rt.jar;%java_home%\lib\dt.jar;%java_home%\lib\tools.jar;%java_home%\common\lib\ Serlvet-api.jar;%java_home%\jre\lib\jsp-api.jar;%java_home%\jre\lib\servlet-api.jar;

There is jsp-api.jar under the Tomcat installation directory \common\lib, add it to the CLASSPATH variable.

If you use command jargon, you can temporarily specify the CLASSPATH variable:
Javac Abc.java-classpath%classpath%; Tomcat installation directory \common\lib\jsp-api.jar (additional packages can be added later, separated by semicolons)

It is best to add the jar package path to the system variable CLASSPATH.
My Computer--right-click Properties--Advanced--Click the New button under the system variable (if not already)--double-clicking the classpath variable or point edit--to add the path to each package (including the jar file name) to the existing Classpath value, OK.
