[Former Member]

Hi,

I'm getting NullPointerException when starting SAPGUI 7.40 rev 2 on my Linux box (RedHat Enterprise Linux 7.2 / Open Client).

[nza@t450 bin]$ ./guilogon

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

(This conf above is with 32bit Java, but is failing with the system-default 64bit 1.8.0_91-b14 Oracle Java too)

Solved.

The cause of NPE has been messed up config SAPGUILandscape.xml and/or other files. I had to remove local settings, ie,

$rm -r ~/.SAPGUI/

then restart the application and NPE is gone...

Hi Nobert,

Hi Prithviraj,

thanks for your reply.

The latter two pages are password protected I cannot open.

Regarding the first link, I downloaded the documentation, went through it and I think my conf is fulfilling the system requirements, such as

• Oracle Java SE 8 32- or 64-bit (update 25 or newer)
• C++ runtime: libstdc++.so.6
• Red Hat Enterprise Linux 7

My conf is an up-to-date OpenClient RHEL 7.2, yet I cannot run SAPGUI 7.40r2.
