Mango M2M Community

Hi!

I'm trying to run Mango in Windows 7 64bit. Tomcat starts with no errors but when I access http://localhost:8080 I get the following error:

org.apache.jasper.JasperException: An exception occurred processing JSP page /WEB-INF/jsp/login.jsp at line 20

Any ideas?

Something's up with the locale that your browser is providing. Try replacing the seroUtils.jar file in WEB-INF/lib with the attached and restart. See what difference it makes. You'll probably see a lot of "???xxx???" kinds of things, but it beats stack traces.

That did the trick, thanks!

Although as you said, there are ???xxx???'s everywhere.

I tried it before with Opera 10.5, Internet Explorer 8 and Google Chrome but got the same error every time.

Got any hints how to fix this problem for good?

What language is your browser set to? I.e. in FF, Tool -> Options -> Content -> Languages -> Choose, what is the top language listed?

It says [fi-fi] in Firefox and Finnish (Finland) [fi-FI] in Internet Explorer 8.

If I change it to [en-us] works like a charm. So no support for Finnish language?

No, there's no translation, but it is supposed to fail over to English (the most complete translation). Thanks for the report.

Hi,

FYI, I have exactly the same problem with a french OS/browser : same error, same solution.

I tried different Windows versions (Seven Pro, Vista Pro, XP Pro) and different browsers (IE, Firefox, Chrome). Indeed the only solution was to change the browser langage from [fr-FR] to [en-US].

K, thanks.

Can you please try the following:

- find the WEB-INF/classes directory
- delete messages.properties
- rename messages_en.properties to messages.properties
- restart Mango
- try again

Let me know what happens. This will hopefully default your language to English.

I tried what you suggested : now, Mango seems to default to english whatever the browser's language is. Tested with Chrome and Firefox, locales set to [fr-FR].

Thanks !
