JavaWeb development typically requires the use of web containers like Apache Tomcat or JBoss.

On the other hand, Java language can be used to develop various types of applications, including desktop applications, mobile applications, embedded applications, etc. Java language has rich class libraries and tool support, which can meet the needs of various application development. The characteristics of Java language include object-oriented, portability, cross-platform compatibility, etc.

In conclusion, JavaWeb is the application of the Java language in the field of web development, while Java is a programming language with a wide range of applications.
