Web browser not started by java gui 7.20

[benoit-schmid]

Hello,

I use the java gui 7.20 on Linux.

When I click a link icon that points to a document on my content server, it does not start a web browser

to open the url.

Would you know how I could trace the problem?

Thanks in advance for your help

Hello,

this might be related to old ABAP API used to launch the external process, which is no longer supported in SAP GUI for Java 7.20. Please refer to [SAP note 1418688 - SAP GUI for Java 7.20: Graphics and GMUX functionality|https://service.sap.com/sap/support/notes/1418688] and referred notes for ABAP corrections to address the issue.

Best regards

Hello Rolf,

Do I have a way to ensure that it is because of GMUX, that I can not load this url?

Hello,

you can verify with following steps:

Please enable tracing according to [note 683960|https://service.sap.com/sap/support/notes/683960] and add trace keys GMUX and C_GMUX by removing the comment symbols in front of the last two lines of the list.

Then perform the steps, which should result in opening that URL in the browser.

Open the trace file and search for "GMUX Request".

In case there are such entries, the corrections part of [note 1444941|https://service.sap.com/sap/support/notes/1444941] should solve your problem.

Otherwise you might want to create a support message on component BC-FES-JAV, so we can look into this.

Best regards

Hello,

I see this in the trace:

22.06. 11:00:13.304 CON: GuiNiNetConnection: sending DIAG data to connection for modus 0

22.06. 11:00:13.305 C_GMUX: GMUX Request: Blob of 546 bytes

22.06. 11:00:13.305 C_GMUX: ...

Therefore you must be right it is a GMUX call which is not supported by 7.20.

Thanks for your help.

Hello,

so, the ABAP changes note 1444941 is referring to will change function module WS_EXECUTE to use CL_GUI_FRONTEND_SERVICES internally instead of old GMUX based functionality which no longer is included in SAP GUI for Java.

Best regards
