Java is one of the most actively evolving languages with regard to the development of new APIs, libraries, and tools. It is applicable to problems ranging from embedded systems to enterprise applications. We invite papers exploring all aspects of Java programming; in particular we seek research papers covering the principles of programming in Java, teaching and experience reports dealing with the practice of Java programming as well as papers introducing new kinds of frameworks and tools which have been developed using Java.

All papers must represent original and unpublished work that is not currently under review. Each paper will be reviewed by at least three independent referees. Papers will be evaluated according to their significance, originality, technical content, style, clarity, and relevance to the conference. At least one author of each accepted paper is expected to attend the conference.

Four types of paper submissions will be accepted: research papers, experience reports, industry papers, and demo papers. Submitted papers should clearly indicate their type.

The conference proceedings will be published as part of the ACM International Proceedings Series and will be disseminated through the ACM Digital Library. We will invite the authors of the best papers to provide an extended version for a special issue of Elsevier Science of Computer Programming.

Research and experience papers must not exceed 10 pages while Demo and Industry papers must not exceed 4 pages. The required format for the submission is the ACM SIG Proceedings Style. Please apply the ACM Computing Classification categories and terms. The ACM Computing Classification scheme can be found at http://www.acm.org/class/1998/. The author kit containing the Latex, Word and Word Perfect templates for the required style can be found at http://www.acm.org/sigs/pubs/proceed/template.html.

Workshop and tutorial sessions will be held during one half-day of the conference. Tutorials should last 1,5 to 2 hours, workshops should last 2 to 4 hours. Workshop sessions may include a submission and review process of short papers (max 4 pages), and should include a discussion session. Tutorials should focus on a particular technique, software or methodology. Workshop papers will be published with the conference proceedings.

Workshop and tutorial proposals should be no longer than four pages, should describe the background and focus of the workshop, the background of the workshop organizing committee and the estimated number of participants. Proposals should also include a draft Call for Papers.

The organizers of PPPJ 2007 will provide a meeting room and it is currently intended to publish workshop proceedings along with the PPPJ proceedings in the ACM International Conference Proceedings series. All other issues related to proposed workshops will have to be planned and organized by the workshop organizing committee.
