The Distributed Java Object System adds advanced naming, persistence, security, mobility, and load balancing features to Java's basic RMI communications package. Security is provided through a combination of capabilities [Dennis and Van Horn 1966] and ACLs [Saltzer 1974] that combines some

Java Object XML Mapping (JOXM) is a library that supports the automated persistence and querying of Java objects in a native XML database. The goal of this library is to provide a suitable alternative to standard object-relational mapping (ORM) tools, most notably Hibernate [3]. Unlike techniques

Fault insertion based techniques have been used for measuring test adequacy and testability of programs. Mutation analysis inserts faults into a program with the goal of creating mutation-adequate test sets that distinguish the mutant from the original program. Software testability is measured by calculating the probability that a program will fail on the next test input coming from a predefined input distribution, given that the software includes a fault. Inserted faults must represent plausible errors. It is relatively

In this paper we discuss the engineering requirements for adding object mobility to the Java programming language, and give an overview of the design and implementation of our mobile object system. We show that it is helpful to cluster objects for mobility, and that if these clusters represent

. We propose a new object mutation approach along with a set of mutation operators and support tools for inserting faults into objects that instantiate items from common Java libraries heavily used in commercial software as well as user defined classes. Preliminary evaluation of our technique shows

no longer uniformly accessible for all objects. The extra overhead to obtain this information is won back again for most benchmarks by the better memory layout in the heap. As a result we obtain applications that run equally fast, but allocate less memory. Keywords—Java, memory management, 64-bit, Implicit

Many secure applications are emerging using the Java TM language and running on the Java platform. In dealing with Java security issues, especially when building secure mobile agents on the Java platform, we inevitably depend on the underlying object orientation, such as data encapsulation

Abstract. Distributed Java applications use remote method invocation as a communication means between distributed objects. The ProActive library provides high level primitives and strong semantic guarantees for programming Java applications with distributed, mobile, secured components. We present a

problem, because object semantics are defined by the programmer and can vary widely. We develop mutation operators and support tools that can mutate Java library items that are heavily used in commercial software. Our mutation engine can support reusable libraries of mutation components to inject faults
