Deploying java applications in resource constrained environments

An apparatus for deploying an application in a resource constrained environment, the application comprising a computer program written in the Java® computer programming language, the apparatus comprising a computer processor, a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions capable of:

• identifying a resource constraint of a target system including identifying a target system having limited processing capacity;
• filtering the application in dependence upon the identified resource constraint including:
• preprocessing a tag library of the application, including identifying a tag library descriptor of the application and copying a listener from the tag library descriptor to a deployment descriptor for the application;
• identifying a hierarchy of classes of the application stored in a single file;
• storing each class of the hierarchy as a separate file accessible to the application;
• and
• identifying to a runtime platform the copying of the listener from the tag library descriptor to the deployment descriptor, including setting a flag in the application.
