[FIXED] package javax.servlet does not exist although the package is found by vsCode

Issue

When importing the javax.servlet package in the java file, this package is found by vsCode. However, when I compiled the file I get the error 'package javax.servlet does not exist'. I don't know how to solve this problem. I cleared workspace, but it doesn't work. Tomcat5.5,vsCode1.67.2,java1.5,jdk1.5

Solution

In case the source files reference third-party library (JAR) files, use the -cp option and specify the JAR file. For example:

javac -cp lib\mysql-connector-java-8.0.27.jar -d classes src\TestDb.java

If there are multiple JAR files, they must be separated by semicolon like this:

javac -cp lib\mysql-connector-java-8.0.27.jar;lib\log4j-1.2.17.jar -d classes src\TestDb.java
