Hi,I am unable to deploy a portlet in liferay DXP.
I use Liferay DXP 7.1 with Tomcat 8. I am testing under chrome browser.When I click on the deploy button   , nothing happened and I get the following JS error: 
Uncaught TypeError: Cannot read property 'fr_FR' of undefined
I get an http 500 loading this file : o/frontend-js-web/liferay/available_languages.jsp

On firefox, the error message is :  Liferay.Language.direction is undefined.I already tried on Liferay portal 7.0 and 7.2 and I have the same error.

I think the french language doesn't work on this platform,  did you implement it ?How can I fix that ?  I tried change the language with en_US but I get the same issue.
I also try to deploy by copying my war file on /deploy folder but, the portlet seems to be not deployed, I can't find it on the portlet list and I don't have any error message.
Regards.

There is something wrong with your environment because french language support works on 7.0, 7.1 and 7.2.

Hello David,
Thank you for your prompt response.
Sorry but I can't find any environment problem I just follow the documentation to implement the DXP Portal : https://portal.liferay.dev/docs/7-1/deploy/-/knowledge_base/d/installing-liferay.
I tried to change the default language editing portal-ext.properties , adding:company.default.locale=en_US
But I have still the same problem.Do not you have any ideas of where that might come from ? 

Regards

If this is a basic install, then whatever changes you have made could be the source of the issue.  Have you made any changes to tomcat's setenv.sh?

Any other environment variables defined or settings in portal-ext.properties which may be affecting this?

Hi David,
I have made no changes on tomcat's setenv.sh. 
Otherwise I just added the "company.default.locale" property in the portal-ext.properties :

jdbc.default.jndi.name=jdbc/lportalDb
jdbc.default.driverClassName=com.mysql.jdbc.Driver
jdbc.default.url=jdbc:mysql://127.0.0.1:3306/lportal
jdbc.default.username=root        
jdbc.default.password=root
company.default.locale=en_US

But I have still the same error.It seems related to this exception :  code="500", msg="", uri=/o/frontend-js-web/liferay/available_languages.jsp.
I also tried to launch it through an other tomcat that I downloaded but still same issue.

Regards.

Hi,
I think it is related to this issue : https://liferay.dev/forums/-/message_boards/message/113745476
Same exception on the log, starting the server : java.lang.ClassFormatError: Truncated class file.
Regards.
