JSmooth

JSmooth is a Java Executable Wrapper that builds standard Windows executable binaries (.exe) that launch java applications. Such binaries contain all the information needed to launch your java application, i.e. the classpath, the java properties, the jvm version required, and so on. If Java is not installed, it helps the users by displaying them a notice before launching automatically a browser to a web site where they can download a JVM.

This is a fork of JSmooth 0.9.9-7, with these additional features:

• 64bit support.
• Autodownload wrapper enhancements.
• VERSIONINFO support.
• Custom Java home environment variable.
• Pass Java system properties via command line.
• Native win32 dialogs.

There's no additional UI for configuring the above features. You'll have to edit your .jsmooth file manually.

Installing

Dowload and extract the latest release to a local folder.

Using the software

See the original JSmooth's manual.

Additional features

64bit support

To create a 64bit executable, use one of the new x64 skeletons:

• Autodownload Wrapper x64
• Console Wrapper x64
• Windowed Wrapper x64
• WinService Wrapper x64

A 64bit executable needs a 64bit JRE.

Autodownload wrapper enhancements

The Autodownload Wrapper skeleton has been enhanced:

• The DownloadURL property may point to local file using the file: prefix. I.e. file:myjre\jre.exe (use backslash for path information).

• The DownloadURL property may point to a file called autodownload.redirect. This file consists of the effective URL and optional parameters passing to the executable:

  url=http://mysite/jre.exe
  params=/s
  

  The URL can again point also to a local file using the file: prefix.

VERSIONINFO support

To include a VERSIONINFO resource into the generated .exe, add this XML fragment to your .jsmooth file:

<versionInfo>
    <binaryFileVersion>99.99.0.0</binaryFileVersion>
    <binaryProductVersion>99.99.0.0</binaryProductVersion>
    <productVersion>99.99.0.0 HEAD-Build14618</productVersion>
    <productName>my app</productName>
    <legalCopyright>Copyright (C) 2016 - My company</legalCopyright>
    <companyName>My company</companyName>
    <originalFilename>myapp.exe</originalFilename>
    <fileDescription>myapp.exe</fileDescription>
</versionInfo>

See the Microsoft Documentation for a description of all the elements.

Custom Java home environment variable

Besides searching for the JRE at the fixed locations JAVA_HOME, JRE_HOME etc, one can specify a custom environment variable:

...
<JVMSearchPath>customjavahome=MY_JAVA_HOME</JVMSearchPath>
...

This will search for a JRE at the location contained in the environment variable MY_JAVA_HOME.

Pass Java system properties via command line

Pass a system property on the command line:

myapp.exe -Dmyprop=myvalue

This will create a system property named myprop with the value myvalue.

A previously defined property with the same name will be overwritten.

Build

• Download Apache Ant
• In build.xml, Change paths to mingw and jre to match your environment
• In a shell, call ant dist (running Ant task from inside Eclipse did not work)
