1 Introduction to SunOne Development Tools by Mr. Mickey Fan, Java Architect, Sun Microsystems Good morning. Ladies and Gentlemen. the mobile edition. I am glad to be invited to be here. Today my topic is Sun One Studio, Sun One Studio got 3 different editions. I think I don't have time to give the features of all the editions. I'll focus on mobile today because it is a wireless activity. I'll try to have some demonstrations and to give you some idea about the next generation mobile of application tool. To start with, I'll give you some idea about J2ME today & tomorrow and talk about the deployment situation in HK, especially on how many J2ME phones are available on the market. I think for the last two years, Sun Microsystem in HK has been very focused on J2ME deployment. Especially in HK, we arranged a lot of competition, and a lot of activities to show the developers how to make use of J2ME to deploy their application. Today, I think the deployment situation in HK is very good especially via Motorola, Nokia and Siemens and maybe later Sony Ericsson. We'll also talk about SunOne Studio with some demonstration and also the mobile edition. This is one of the diagrams I copy and paste from my corporation. It says about the trend of the wireless industry and the overall web service deployment. I think we are somewhere here in IPv4, and RMI/IIOP. We can see that more and

2 more devices will be web enabled or internet enabled or IP enabled: mobile phone, internet game, and also some sort of embedded device Java card. When we talk about devices on the web, we notice that we need some mechanism to look up the resources on the web and the different type of services. I think one of the problems we have is the identity. Since a device needs to identify itself on the web, we may use the same PKI mechanism, or some sort of XML based identification mechanism to identify the one actually making use of the device. With IPv4, the designed quality of service is not good enough for the operators to deliver the bandwidth promised to their customers in the different packages. IPv6 actually is faster since it has more simplified header. It therefore allows the operators to satisfy the QoS requirement of their broadband end-users. Also IPv6 will have more development on the web, more different network architecture on the web, JINI and JXTA which is just the peer-to-peer computer mechanism. The mechanism enables the network to survive in disaster since it doesn't have any centralised server. We'll talk about look-up services and how different network can work together. This is another slide which I paste from our corporate. In fact it is about end-to-end JAVA and it shows products ranging from the Java card to machines with more than 100 CPU's that are implemented and based on JAVA. Maybe unluckily we don't have microwave oven making use of JAVA but luckily we have JAVA phones, set-top-box based JAVA card and also CE device based on Java. Looking at the slide on J2ME devices, I think you would agree that the choices of J2ME devices are plentiful. Those devices shown here make up only a subset of devices currently on the market. There are a lot of devices which you can choose to

3 develop your applications. For example, on the first row, most of the phones are implemented and deployed in Japan, for example the PHS & PDA. On the second row, you can see some models from Motorola deployed in the U.S., in connection with the iden network, and also some products from Nokia, based on GSM and GPRS. On the last row are mostly Palm based device. In fact, I think last year we've already deployed and implemented Java Virtual Machine in Palm OS devices. As for HK, there are currently on the market seven or eight J2ME enabled devices from Motorola, Nokia, and Siemens. I think by the end of this year, more & more J2ME phones will be available on the market, most of them from Nokia, Motorola, Sony Ericsson and maybe Samsung, who has a plan to launch J2ME phones on the market. With more J2ME phones available on the market, there will be more choices, price will be cheaper, and applications will multiply. J2ME is not only about games. Games I think is the entry point for you to develop applications. Games are easy to write. It is very easy to kick-start your application development based on a single J2ME game application on your mobile phone. As for a large scale J2ME based deployment, like the I-mode in DoCoMo in Japan, their concern is not just game but also partnership with different parties. For example, after they launched the I-mode center or I-mode services, they have had already some bank or Internet based content services and IP based services in place. So I don't think one can build J2ME game alone, One should look for very large-scale application and new value-added services. In fact in HK, we work with CSL to deploy an OTA ( over the air ) provisioning project which enables one to download applications off the air onto

4 mobile phones. What I mean is actually : make use of WAP or other technology to select the application you want and after that you can just make use of the wireless network to download the application. In fact, it is a partnership model in connection with CSL. If you are a developer, you can post your application on the web. After the application has been approved, a CSL customer can download your application based on this OTA mechanism. They may charge the end customer $10 or $50 per game or per application. After that they can share revenue with you. I think that is a good business model. You may wish to visit the CSL web site for more details of this mechanism. This slide is about MIDP 1.0. Since some of you may have worked on J2ME before, I don't want to go through that one by one. In fact the P1.0 can handle the basic application control, like Applet and GOI control, graphic design event, some simple database, internet connection and timer event for animation. Most of the JSR is already there, for example, JAVA game profile, J2ME multimedia profile and also the next generation MIDP. I think you are interested in having a look of how the next generation J2ME works. I have an application already installed here, you may find it quite interesting. For example, this is wireless 2.0. This is based on the new JAVA game API. For example, if I got an application here, I try to run it JAVA Game API DEMO So SUN and wireless. In fact wireless is central to SUN strategy. It is about centralised server, computer resources centralised in the service side and also different kind of mobile devices which can be connected to the web. So SUN One studio 4.0 has 3 different editions, in fact I think you may be interested to know

5 why we call it Sun ONE today. In the past we called it the integrated development environment FORTE for JAVA and also the e-commerce infrastructure software I- planet. Now we unify the two software under the name SUN ONE: Sun One studio for the development tools, Sun One application server for the e-commerce software and the infrastructure software. It seems easier for our customer to recognise our new name. So for the Sun One studio 4.0, in fact we have 3 different editions. The first one is called community edition, which is free of charge. It supports the basic J2SE development and also part of J2EE development such as JSP, servlets and some standard Tag Library. If you want to build web-based application, this community application is good for you. And also it is free of charge for download at sun.com. Today I would like to talk about the mobile edition, and the support for J2ME development, especially for the MIDP/CLDC scenario. Also we have another edition, called the enterprise edition, which is not free of charge. In fact if you want to deploy your application, the J2EE application, we have a module supporting multiple application servers, not just application server from SUN, but also those from others like Oracle. In fact today I don't have enough time to talk about the application. I think Sun always has an open mind, with regard to the mobile edition and the enterprise edition being able to support different kinds of application servers. I think most of the IDEs ( integrated development environments) are quite similar. I don't want to demonstrate the basic features of them. I want to show to you how to make use of it in different emulator environment. For example, I want to build a basic Java program...

6 DEMO If you are a developer currently looking for JAVA development, there is a very good development tool called ANT. [In the demonstrations that followed, the speaker showed the capabilities of the various Java IDEs. ] DEMO So you know that the Sun One Studio actually integrated with the ANT tools, ANT tools are not just about the mobile application. Also applicable to J2EE and J2SE. A lot of application servers are already integrated with them. Switching back to the J2ME development concerning MIDP... DEMO One of the amazing things is that this J2ME application is already up and running. It is a very simple J2ME application. If I don't want to make use of the Sony Ericsson emulator, what next...maybe I just go through the programme first...i can make use of the Motorola one. DEMO We call it UEI, unified emulator interface, which enables different device emulators of phone manufacturers to work with us. On top of that, I think we also

7 support Palm. DEMO So in fact, we can make use of Palm based on a single interface. Different types of devices can work inside J2ME or Forte SUN ONE Studio environment. So it is the end of my demonstration. Forte for Java or maybe Sun One Studio Mobile Edition, which are free, and the fully integrated IDE complete with plug-in emulators and templates can help you build applications and debug your software. After that how do you deploy your application into your J2ME phone, from different phone manufacturers? I have a file system here. I have the MIDLET suite jav file and also the JAD file. You can just copy these two files to your Nokia J2ME phone by making use of the infra-red link. The Nokia phone will regard the copied files as a message. If you click on that message, it will automatically install this JAVA application for you. As another example, if you use the Siemens J2ME phone, you can copy this application into the SD card. After that you can just click on this application and it will launch this application onto the Siemens J2ME phone. The same thing happens in the Motorola environment. So starting J2ME development at home or in your company is a very easy thing. Just download the application, then build the application and then copy the file to that environment. It is then up and running. Other than that, we also support version control and ANT. In the environment I'm showing you, you can click the debug point here to debug your application. We already have 4 partners committed to building a UEI environment. I think it is more than that. It is the Nokia emulator 6310i. In fact this 6310i is already deployed in other countries, maybe in Australia. I think a lot of people have probably heard about the next generation Nokia J2ME phone 7210,

8 another colour phone with a smaller size. Also Siemens mobile, they have different J2ME phone, I think it is one of the least expensive J2ME phone on the market. Also Sony Ericsson. They got some J2ME phone with camera embedded in the device. So one of the benefits of Sun One Studio I think is the UEI, unified emulator interface, an interface to let our partner integrate their emulator into our Sun One Studio environment. Think about that if I got two different IDEs like Sun One and one from other company. Different device emulator will have their own SDK, so in every different IDE you need to write a specific module to enable that IDE to talk with each device emulator. If you have four different IDEs, it is tedious to write four modules for each of the different emulator environments. If I have a UEI emulator interface, different IDEs can be adapted to different environments. In fact the Sun One Studio make use of UEI to talk with different UEI at the same time. As a summary, JAVA is moving. So are J2ME, Java card, set-top box. JAVA is not a single company technology. It can be regarded as a democratic system. I can make use of J2ME technology to work with Motorola, Nokia, Sony Ericsson in building J2ME application. It is not a technology restricted to a single vendor. In a single vendor environment, if something goes wrong with that vendor, that technology may be at risk. An example is Sequel Window which was very hot 5 years ago. Now it is no longer being developed. This is not the case with Java. Java is not a single vendor system. It is based on a democratic system in which the JCP works with different partners on its development. This is the end of my presentation. Thanks a lot.
