OLAT : defaultcharset=UTF-8

[Vivek Loke]

Hi,

 

Please suggest.

 

We found some below changes inside 9.4 version.

 

# abort system startup when no UTF-8 capable file system is detected. In production this should be set to

# true to prevent accidental startup with another encoding which leads to a big data mess

enforce.utf8.filesystem=true

 

we got the below error once I run the setup please need suggest your inputs on same.

 

 

 

SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.olat.core.util.WebappHelper' defined in class path resource [org/olat/core/util/_spring/utilCorecontext.xml]: Invocation of init method failed; nested exception is org.springframework.beans.factory.BeanInitializationException: System startup aborted to to file system missconfiguration. See previous warnings in logfile and fix your Java environment. This check can be disabled by setting enforce.utf8.filesystem=false, but be aware that the decision to use a certain encoding on the filesystem is a one-time decision. You can not cange to UTF-8 later!

Hi Vivek

The configuration makes sure that the system only boots when the filesystem is properly configured and runs in an UTF-8 environment. In case you don't want this, you have to set this flag to false. 

In your case you are starting tomcat in a way that the java environment is not set to UTF-8. This is not necessarily a problem, however if you want to support all kind of languages (e.g. non-ASCII and non-ISO-Latin characters, you really should run OpenOLAT with a UTF-8 file system. Setting the encoding can be tricky and depends on your operating system. Look up your operating system manual how to do this and which variable you have to set to correctly set the environment for the java virtual machine. It is not possible to set the encoding from within Java, you have to set it in your operating system environment.

Note that you can not change the encoding if you already have data. In that case all the filenames in olatdata need to be converted from the old to the new encoding. On Linux you could use the program iconv to do this. 

Cheers

Florian
