If users receive unexpected results in a Web browser (such as errors or incorrect information), you might have a problem with the Web components in the application. The runtime environment for Web components is called the Web container. This paper discusses techniques for diagnosing problems that can occur in the Web container.

Potential symptoms of a Web container problem can include:

- Users are not able to access a Web component

- Unexpected behavior when running a Web component

- Errors when starting a Web component

- Problems with JSP™ compilation

- Errors or exceptions thrown when running a Web component

- Messages starting with SRVE (Web container), JSPG (JSPs), or JSFG (JSF)

Problems areas that are related to the Web container also include session management problems and character encoding problems.
