This article shows how implementations of the Service Locator pattern that include a resource cache can cause code to run incorrectly in J2EE 1.3 and later versions. While the Service Locator pattern itself is still useful, this article will show how caching with this pattern is harmful rather than helpful, why it should be eliminated from service locator implementations, and offer some practical alternatives.
