How can developers handle exceptions in Liferay?

Handling exceptions in Liferay effectively is crucial for creating robust applications. Utilizing try-catch blocks combined with implementing error handling components is a fundamental approach that allows developers to gracefully manage unexpected situations. By encapsulating potentially problematic code within try-catch blocks, developers can respond to exceptions in a controlled manner.

This approach enables the implementation of specific error handling components that can provide user-friendly messages, log errors for future analysis, and even trigger alternative workflows. It enhances the overall user experience by allowing applications to recover without abrupt failures or unhandled exceptions.

The use of Liferay's logging framework can complement this approach by logging exceptions for insight and analysis, but it is not the primary method of handling exceptions. Similarly, relying solely on removing code that could cause exceptions is not a feasible solution, as it can lead to loss of functionality. Built-in error pages provide a user interface for error messages, but they do not inherently manage the exceptions themselves. Therefore, employing try-catch blocks along with error handling components is the most comprehensive strategy for exception management in Liferay.
