Weblogic mime type configuration Steps
Few times its seen that when weblogic is used to serve as a webserver or used to download files via some deployed application, the file comes corrupted or with junk characters.
We had the same issue where excel files were not able to render properly instead it will open in html format rendering all junk characters, to avoid this situation we have followed below step to fix weblogic mime type configuration issue.
Error:
Mime Type Missing Error in Weblogic while opening a excel file
In weblogic 5.x and 6.x there use to be a property where you can set the mimetypes on the fly but thease are depricated in later versions. You can read more about the weblogic 5.x,6.x mimetype here.
For the newer version of weblogic please use the steps provided below.
Note: We have used weblogic 11g for the example here.
1. Here we are creating a domain wide mime types mimemappings.properties file to define a type for the “.extension” extension.
2. Login to admin console as admin user.
3. Navigate to Your Domain > Web Applications
Weblogic Admin Console Domain
4. Make sure below path to properties file is present, if not please add it.
Weblogic Mime Types Property location
5. Login to the weblogic host machine and cd to /HOME/Middleware/user_projects/domains/Your_domain/config folder. create a new mimemappings.properties file and add entries like below to register the new file extension.
xlsx=application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
docx=application/vnd.openxmlformats-officedocument.wordprocessingml.document
Sample Entries List to refer:
Note: Care shall be taken while putting the mimetypes. The format needs to be used is extension=mime-type as given above in bold letters, below example mime-types are in mime-type=extension format and only for reference. Do not copy paste blindly.

6. After adding all the mimetypes save the file and restart the weblogic server and check.
7. Few tips to remember, if you want to remove a mime type from the server default mimetypes you can just leave blank after the extension text. Example :
xlsm=
8. Make sure you do a complete temp and cache cleanup before you restart the weblogic servers and clean browser cache before you test the mimetype settings.

Hi,
First, thanks for this post, it help me a lot.
I tried this solution but it didn’t work, so I did a change and works for me, the solution is extension=mime-type ,not mime-type=extension.
svg=image/svg+xml
# Defines some mapping between filename extension and MIME type: extension=mime-type
I took the idea from this place:

Regards,
Thanks jorgitoito. It was only sample values for reference on which mime-type is for which extension. It is good that you pointed out that its not clear. I have added a new note before the example so that other readers will not copy paste directly.
Hi Ramakanta,
I have the same problem, the file comes corrupted or with junk characters at begin of file and when I open the file with notepad++ and remove the fisrt eight characters I can open the “.xls”.
later 30 minutes I apply your changes of mimemappings.properties but didn’t work.
later away I read the next post:
https://community.oracle.com/thread/1100188?tstart=0
And finally, I put:
response.reset();
before the line of :
response.setContentType(“application/vnd.ms-excel”);
and its working fine!
That’s informative. Surely it will help others. Thanks for sharing.
