JHTML File Extension

What is JHTML file?

Files with the JHTML extension have a textual format and store HTML code combined with Java object code written in special tags. This standard, called Java Hyper Text Markup Language or Java in HTML, was developed by Art Technology Group - ATG. The company was fully acquired by Oracle in 2011. The execution of the code is possible thanks to the operation of a dedicated server configured to handle JHTML page requests.

How do JHTML files work? - server processing

Handling files with the JHTML extension is only possible on dedicated servers. It goes as follows:

1. A JHTML page request appears, usually from the client's browser.
2. The request is passed on to the server handling the Java application standard.
3. The JHTML page is compiled into a .Java file and then a .class file.
4. The server launches the code as a servlet passing the HTTP/HTML stream.
5. The resulting code reaches the client's browser.

This solution allows for dynamic code generation of the page. It can, for example, be based on queries to a database that are in the JHTML code, using the JDBC interface - Java Database Connectivity.

Comparable solutions to JHTML

The operation of the JHTML file handling standard can be compared to the Microsoft Active Server Page or PHP service. It's about modifying the page code before it is delivered to the client. The standard developed by ATG is proprietary. Based on it, a licensed solution JSP was created by Sun Microsystems.

Step 2. Update Mozilla Firefox to the latest version

You still cannot access JHTML files although Mozilla Firefox is installed on your system? Make sure that the software is up to date. It may also happen that software creators by updating their applications add compatibility with other, newer file formats. The reason that Mozilla Firefox cannot handle files with JHTML may be that the software is outdated. All of the file formats that were handled just fine by the previous versions of given program should be also possible to open using Mozilla Firefox.

Step 3. Assign Mozilla Firefox to JHTML files

The procedure to change the default program in Windows

• Right-click the JHTML file and choose Open with option
• Next, select the Choose another app option and then using More apps open the list of available applications
• Finally select Look for another app on this PC, point to the folder where Mozilla Firefox is installed, check the Always use this app to open JHTML files box and conform your selection by clicking OK button

• Find the Open with option – click the title if its hidden
• Select the appropriate software and save your settings by clicking Change all
• A message window should appear informing that This change will be applied to all files with JHTML extension. By clicking Continue you confirm your selection.

Step 4. Verify that the JHTML is not faulty

If you followed the instructions form the previous steps yet the issue is still not solved, you should verify the JHTML file in question. It is probable that the file is corrupted and thus cannot be accessed.

1. Check the JHTML file for viruses or malware

If the JHTML is indeed infected, it is possible that the malware is blocking it from opening. It is advised to scan the system for viruses and malware as soon as possible or use an online antivirus scanner. If the JHTML file is indeed infected follow the instructions below.

2. Verify that the JHTML file’s structure is intact

Did you receive the JHTML file in question from a different person? Ask him/her to send it one more time. It is possible that the file has not been properly copied to a data storage and is incomplete and therefore cannot be opened. It could happen the the download process of file with JHTML extension was interrupted and the file data is defective. Download the file again from the same source.

3. Verify whether your account has administrative rights

Sometimes in order to access files user need to have administrative privileges. Log out of your current account and log in to an account with sufficient access privileges. Then open the Java HTML Web Page file.

4. Verify that your device fulfills the requirements to be able to open Mozilla Firefox

If the system is under havy load, it may not be able to handle the program that you use to open files with JHTML extension. In this case close the other applications.

5. Verify that your operating system and drivers are up to date
