Build Options / JExpress Wizard

Build Options

After you've set all the options in the other panels, then use the Build panel to create your installers, and optionally autoupdaters.

If a JVM file isn't installed: If any of the installers that can include the JVM are grayed out, then follow these instructions.

If there are any errors during the Build, look up each error number for suggestions and work arounds. After JExpress builds your installer, learn more about testing your system and the location of your distribution files. Click on the jump point or just page down to learn more about each setting on this panel.

Version

Specify the current version number or method of distinguishing this release from previous releases. This information displays on your install program's splash screen.

Build directory

The Build directory is where JExpress prepares your files for distribution. We recommend that this directory be a new directory so JExpress doesn't interfere with other files on your system.

JExpress defaults the Build directory to a subdirectory in your JExpress directory that matches your project's name. You can leave this field blank if you want to use the default, and JExpress will name and create the directory when you name the project.

Learn more about where JExpress stores your distribution files after it builds your installer.

Erase all of the Build directory before using

Check this box if you'd like JExpress to erase all the files in the Build directory and its subdirectories before JExpress creates a new distribution.

IMPORTANT: If you check this box, then JExpress will delete all subdirectories. On Unix, be very careful about linking to other directories to the Build directory. For example, if you'd link the root to the Build directory and then check this field, JExpress could delete all files on the drive.

Installers

Add a check mark to all of the checkboxes to indicate which types of installers you want created for your application. JExpress can create installers that either include the JVM or don't. JExpress can create installers that include the JVM or not. We do not usually include all the JVM files so we suggest that you follow these instructions before you try to build.

If JExpress doesn't currently support a native installer for one of your desired platforms, then you can purchase a JExpress Custom Native license and adapt the native installer to your environment. You must have purchased at least one license to JExpress for each JExpress Custom Native license you purchase.

Windows:

Add a check mark next to the Windows checkbox(es) if you want to build an executable file that installs your application.

When you add a check mark to the Windows checkbox that includes the JVM, then an EXE file is created which automatically detects whether the JVM is on your customers' systems, installs it if it is not, and then installs your application.

If you add a check mark to the Windows checkbox with no JVM, then an EXE file is created which verifies that the correct JVM is installed on your customers' systems, but only reports to the user if it isn't. If the installer finds the correct version of the JVM, then it proceeds to install your application.

Solaris:

Add a check mark next to the Solaris checkbox(es) if you want to build an binary file that installs your application.

When you add a check mark to the Solaris checkbox that includes the JVM, then a binary file is created which automatically detects whether the JVM is on your customers' systems, installs it if it is not, and then installs your application.

If you add a check mark to the Solaris checkbox with no JVM, then a binary file is created which verifies that the correct JVM is installed on your customers' systems, but only reports to the user if it isn't. If the installer finds the correct version of the JVM, then it proceeds to install your application.

Linux:

Add a check mark next to the Linux checkbox(es) if you want to build an binary file that installs your application.

When you add a check mark to the Linux checkbox that includes the JVM, then a binary file is created which automatically detects whether the JVM is on your customers' systems, installs it if it is not, and then installs your application.

If you add a check mark to the Linux checkbox with no JVM, then a binary file is created which verifies that the correct JVM is installed on your customers' systems, but only reports to the user if it isn't. If the installer finds the correct version of the JVM, then it proceeds to install your application.

Pure Java:

Check this box if you want to create a Pure Java installer. The Pure Java installer is more compact than the native installers because it doesn't include the JVM. It also works behind firewalls that don't allow executables, by providing a single JAR file that your customers download and load. Your customer must have the JVM already installed before they can use the pure Java installer.

Build

When you click this button, JExpress saves your project and then builds your installers, and optionally prepares the updates files.
