Evans Data's North American Developer survey polled more than 600 developers and found they were virtually split on development plans for Java and .net.
The survey, completed last month, found that 40% of respondents were developing applications for .net and that 63% will target .net within a year, while 51% develop for Java today and 61% plan to do so next year.
Web services adoption, meanwhile, will jump from 57% now to 87% in 2003, according to the survey.
Some 43% of developers are either deploying Web services applications at present or expect to do so in the next six months. Internal Web services applications are the focus for developers in the initial phase.
Obstacles to Web services deployments include end-to-end security, noted in 24% of responses; ambiguity in standards, cited by 21% of participants; and the technical issue of architecting and integrating services-oriented application architectures, named by 16% of respondents.
Other trends cited in the survey include wireless development, with 48% planning applications in the next year, and Linux development, with 8% citing Linux as their primary operating system (OS) and 15% as a secondary OS. There also is a marked migration from Visual Basic 6.0 and earlier to Visual Basic .Net.
