What is JST file?

The JST file has been categorized as Web Files. The author of this format is Oracle. Additionally, the Web Files category contains 303 of other files. JavaServer Page Document is supported by 3 operating systems. The file will work on , Mac OS, Windows systems, unfortunately not on others. The Adobe Dreamweaver application is recommended to open the file. It was released by Adobe Systems Incorporated. This file type can also be opened by 4 other programs. You can use Adobe Creative Suite, Microsoft Internet Explorer, Java in case Adobe Dreamweaver cannot be used.

How to open JST file?

The main problem with JavaServer Page Document is that the JST file is incorrectly associated with programs. This causes the file JST to open by system applications not designed for this purpose, or to display a message that there is no associated program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the JST file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Adobe Dreamweaver

An often overlooked issue is to make sure that Adobe Dreamweaver is installed on the computer. This can be achieved by typing Adobe Dreamweaver into the operating system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Later in this article you will find a list of programs that can open JST files.

Step 2. Create association of Adobe Dreamweaver with JST files

If the application is or has been freshly installed, but the JST file still does not use the Adobe Dreamweaver program, it means no association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can select the desired program. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. Checking the "Always use the selected program ..." box will permanently associate the JST file with the Adobe Dreamweaver program.

Step 3. Update Adobe Dreamweaver to the latest version

If, despite the association of the Adobe Dreamweaver program with the JavaServer Page Document file, the file still does not open, check the program version and possibly update it to the newest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Adobe Systems Incorporated page and install.

Step 4. Check for the following problems with the JST file

The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. This suggests truncating the JST file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file JST or the program directory. However, remember that not every infected JST file can be recovered, so it is important to take care of regular backups.
A typical compatibility error - the program does not support the older version of the JST file. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for this. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular JST file corruption. You can restore the file from a backup or use Oracle help.
The program indicates that the file is encrypted or corrupted. The encrypted JST files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. Copying the JST file to another location will fix the problem.
This can happen on a file that does not support multiple access. In this case, the JST file is blocked by the first application to open it. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If nothing helps, please reset the device.
