B4J Question java.io.FileNotFoundException: C:\Users\GRUPOV~1\AppData\Local\Temp\2 (denied)

[virpalacios]

Hi, I am programming a request to a webservice several times in a loop.
The program gave me this error java.io.FileNotFoundException: C:\Users\GRUPOV~1\AppData\Local\Temp\2 (denied). I am using a system administrator account. I am Glad if someone have a insight about this issue. I am attaching the code (It runs when you click directly to it). I am running in a windows server 2016 with administrator rights and running it from the windows task scheduler.

This Issue is very similar to https://www.b4x.com/android/forum/threads/posible-bug-in-b4j-with-poststring.83965

Best Regards

j.Release should be moved outside of the If block, though it is not the cause of this error.

Can you upload this project?

Hi Erel, thanks for your promptly answer , sure, I am attaching a small but a complete test program, everything is included data.csv and the request.xml.

CASE SOLVED

Hi Erel, Good News!!!,
The program message was
java.io.FileNotFoundException: C:\Users\GRUPOV~1\AppData\Local\Temp\2 (Access Denied) ,

As I said, this is a windows server 2012 machine , with serveral users, so i tried with other users, however, the program break at 15th iteration (with other user break at second iteration), so I Just Find Offending directory "\2" and renamed it to "\2x" and everything works like a charm. Maybe it is related to autorization schema in windows?. I also read that because I am running a .bat file I need to authorize the cmd command?. But renaming the directory work very fine for me. If someone else have a issue like this, it will be good to add comments to this tread.

Best Regards Erel and have a Good Day

Came across this issue. To fix multiple temp folders for user sessions, do this

Using Group Policies (best practice)​

1. Open Group Policy.
2. In Computer Configuration, Administrative Templates, Windows Components, Terminal Services, Temporary folders, double-click the Do not use temp folders per session setting.
3. To disable the creation of a separate temporary folder for each terminal server session, click Enabled. To enable the creation of a separate temporary folder for each terminal server session, click Disabled.
4. Click OK.
