Sun is to acquire the intellectual property of SavaJe Technologies, a provider of Mobile Java application development tools.
SavaJe offers the SavaJe Mobile Platform, an open Java platform that wireless service providers and handset makers can use to brand and add features to mobile phones.
Sun created Java and last year released the code to the open source community for development of more Java applications.
Sun did not disclose how much it is paying for the privately-held SavaJe, but said it was a small enough amount that it need not be disclosed to shareholders of the publicly-traded Sun.
Sun promised more details about its plans for SavaJe at the JavaOne Conference scheduled for 11 May in San Francisco. It said it expects to close the SavaJe asset acquisition by the end of June.
