B4J Question Java locale language in the IDE logs

[peacemaker]

Hi, All

Tried

Dim jo As JavaObject
jo.InitializeStatic("java.util.Locale").RunMethod("setDefault", Array(jo.GetField("US")))

and

#VirtualMachineArgs: -Duser.language=en -Dfile.encoding=UTF-8 -Dsun.stdout.encoding=UTF-8 -Dsun.stderr.encoding=UTF-8

But currently the output of "java -XshowSettings -version" is:

java.vm.specification.name = Java Virtual Machine Specification
java.vm.specification.vendor = Oracle Corporation
java.vm.specification.version = 14
java.vm.vendor = Oracle Corporation
java.vm.version = 14.0.1+7
jdk.debug = release
line.separator = \r \n
os.arch = amd64
os.name = Windows 10
os.version = 10.0
path.separator = ;
sun.arch.data.model = 64
sun.boot.library.path = d:\Programs\Java\jdk-14.0.1\bin
sun.cpu.endian = little
sun.cpu.isalist = amd64
sun.io.unicode.encoding = UnicodeLittle
sun.java.launcher = SUN_STANDARD
sun.jnu.encoding = Cp1251
sun.management.compiler = HotSpot 64-Bit Tiered Compilers
sun.os.patch.level =
sun.stderr.encoding = cp866
sun.stdout.encoding = cp866
user.dir = d:\Programs\Java\jdk-14.0.1\bin

did not help... How to fix ?

 

[teddybear]

I don't think the error is related to locale language or encoding, it may be an encoding issue with the file name or directory under ..\orion_fw_updater\...

 

[Andrew (Digitwell)]

Can you provide the full error message as text. That can be helpful.

It's just trying to download file:

Sub DownloadAndSave (Url As String, dir1 As String, FileName As String) As ResumableSub
    Dim j As HttpJob
    j.Initialize("", Me)
    j.Download(Url)
    Wait For (j) JobDone(j As HttpJob)
    If j.Success Then
        Dim out As OutputStream = File.OpenOutput(dir1, FileName, False) 'ERROR IS HERE
        File.Copy2(j.GetInputStream, out)
        out.Close
    End If
    j.Release
    Return j.Success
End Sub

I have decoded this error, but question is to make EN output.

 

[Erel]

But currently the output of "java -XshowSettings -version" is:

It has nothing to do with your app process.

Unless you are using Java 16+ you don't need to do anything for the logs to be encoded with UTF8. With Java 16+ there is indeed a new flag that needs to be set.
If you see garbled characters then the problem is somewhere else (but first delete the VM args you set).

 

[peacemaker]

My Java was jdk-14.0.1 here, with this error.

Now removed VM args and tried jdk-19.0.2 - yes, solved, the national error text is visible ! Thanks, Erel !

But
1) How to make EN output of the log messages?
2) Now i indeed do not understand what's wrong with the file creation (copying from the stream): (Syntax error in file name, folder name, or volume label)
And URL and path are fully ASCII. Path is writeable ...

 

[peacemaker]

File name error is solved (it was 0x0D byte at the file name end), but the main topic question is not solved - how to override the Java log output language, just make it always english, at any PC locale language.

Try this. see what it is?

Dim jo As JavaObject
'jo.InitializeStatic("java.util.Locale").RunMethod("setDefault", Array(jo.GetField("US")))
Log(jo.InitializeStatic("java.util.Locale").RunMethod("getDefault", Null))

 

[peacemaker]

Try this

Sub AppStart (Form1 As Form, Args() As String)
    Dim jo As JavaObject
    Log(jo.InitializeStatic("java.util.Locale").RunMethod("getDefault", Null))
    jo.InitializeStatic("java.util.Locale").RunMethod("setDefault", Array(jo.GetField("US")))
    Log(jo.InitializeStatic("java.util.Locale").RunMethod("getDefault", Null))

WARNING: package com.sun.javafx.embed.swing.oldimpl not in javafx.swing

ru_RU
en_US

But it did not help with the log error messages language. Now the root error is fixed and no error message.

I have said that in post #2, I guess your windows language is RU, you need to set it up to EN in system Setting

 

[peacemaker]

Used the environment variable JAVA_TOOL_OPTIONS to set permanently:

-Duser.variant=US -Dnative.encoding=UTF-8 -Duser.country=US -Duser.language=en -Dsun.jnu.encoding=UTF-8 -Dfile.encoding=UTF-8 -Dsun.stdout.encoding=UTF-8 -Dsun.stderr.encoding=UTF-8

Locale was changed, but ...
1) I have found the error message garbled characters are of "Cp1251" encoding page that is assigned to Java settings "native.encoding" and "sun.jnu.encoding"...
2) ... and these 2 settings cannot be changed by commands !!11
Just not changed and that's it.

It was some Java bug fix about it in Java18, but in my Java 19 it does not work any way
It seems, changing is impossible ...
