240968 -
240969 - Java compiles to platform-independent bytecode (.class files),
240970 - which is not directly supported by PC hardware. So a Java
240971 - program needs a Java Runtime Environment (JRE) to run, which
240972 - would either interpret the bytecode instructions or compile
240973 - them to native code on the fly. This in turn means that the
240974 - author of that program has to ensure somehow that the proper
240975 - version of the JRE is installed on an end user system.
240977 - ..
240978 - This aligns with Morris' planning to compile Medit java code into an
240979 - EXE file, reported on 081104 0700. ref SDS 1 YD5I

241049 - In a general case you may not expect that your end users will
241050 - know what a JRE is, how to check its version, and how to
241051 - download and install it. This is especially true for consumer
241052 - applications, such as games or multimedia. And those who
241053 - already have a JRE installed may not like the idea about
241054 - installing a different version, because it may break their
241055 - existing Java applications and favorite applets. Then, even if
241056 - you can make sure the right version of the JRE is properly
241057 - installed on enduser systems, which is quite possible in a
241058 - classroom or enterprise environment, the command line required
241059 - to launch your Java application can be quite long:
241060 -
241061 - java -Xmx200m -cp whatever.jar -Dsome.property MyApp
241063 - ..
241064 - Yes, you may put that line into a batch file and call it
241065 - runme.bat, but it looks so much easier to give your program to
241066 - a friend, teacher or colleague as a single file that can be
241067 - run by a double-click. Or, even better, enable it to be
241068 - installed and uninstalled in a native manner without affecting
241069 - other applications.
241071 - ..
241072 - So it comes as no surprise that the primary motivation for
241073 - seeking a way to convert a Java application into an EXE file
241074 - is to make its deployment and use simpler and safer for an
241075 - average user, that is, a Windows user. What surprises newbie
241076 - Java developers is that the JDK does not offer such
241077 - functionality. Before J2SE 1.4, all you could make with JDK
241078 - tools were
241080 - ..
241081 - The major problem with executable jars is compatibility. The
241082 - default JRE may be of an older version than is required by your
241083 - application or may not have the necessary Java Optional
241084 - Packages (previously known as Standard Extensions) installed.
241085 - For instance, if your app uses the java.nio package introduced
241086 - in Java 2 version 1.4, it will not work on JRE 1.3.x.
241087 - Similarly, if it uses JavaMail 1.3, and the default JRE has
241088 - JavaMail 1.2 or JavaMail is not present at all, the
241089 - double-clicked jar will not run. Fortunately, Sun has created
241090 - a Java application deployment technology that eliminates this
241091 - compatibility problem and adds some nice features. It is part
241092 - of the Java 2 platform since version 1.4 and is called
241093 -
241094 - [On 110725 0922 SDS and Medit java launch failed on c16
241095 - 64-bit mode likely due to compatibility conflicts with
241096 - java, ref SDS 7 ZH8J, as cited in research in the record on

241110 - All the above solutions do not change the fundamental principle
241111 - mentioned in the first section of this article. Whether you
241112 - make an executable jar or create a sophisitacted installer,
241113 - your Java program is still deployed as platform-independent
241114 - bytecode. In the early days of Java, the only way to execute a
241115 - Java program on a common PC hardware was to interpret that
241116 - bytecode. Today, any decent J2SE implementation contains a
241117 - Just-In-Time (JIT) compiler that compiles frequently executed
241118 - methods to native code. So it sounds quite natural to take one
241119 - step further and compile the entire application down to native
241120 - code before it is deployed. Such tools exist and they are
