TAC Login web page show a NullPointerException

[Rizo-Patron]

Having the client Talend Studio open you cannot open the TAC website. This ability was lost now that we are testing 5.0.3. It worked fine in 5.0.2

Hi,
Could you give us the error screenshot of 5.0.3 "Having the client Talend Studio open you cannot open the TAC website. This ability was lost now "? Is there any error log which is located in <Servers>/apache-tomcat-xxx/logs by default.
Best regards
Sabrina

Here the error message. We are working to find any message created by the TAC in the Tomcat log files.
Thanks Sabrina.

Hi
This looks like a bug or there might be a migration issue but could you send a ticket to the support (support@talend.com) with your license information to get a proper support from them?
There is no obvious reason why you couldn't open Studio and TAC at the same time.
And even if this is the case, the error is not enough self-explanatory.

Have you tried to clear your cache before accessing TAC again?

1) The tomcat instance and the org.talend.administrator web application (i.e. TAC) log files do not show any errors on them.
2) The following IS the error message that the TAC throws to /data/talend/5.0.3/logs/administrator.log. This file name parameter is the one defined inside the TAC under log4j Talend Appender.

Hi Elisa,
1) Clearing the cache before accessing TAC does not work.
2) We do have a ticket created yesterday. We will update it with the error message from the log file.
Thank you VERY much for your help.

Hi
I have escalated your issue. Have you checked the catalina or localhost or whatever name the tomcat log has?

[Rizo-Patron]

Hi Elisa
Thank you very much for the escalation.
Yes, we have checked all the catalina and/or localhost and/or all the files names that the tomcat log have. They do not show any errors on them coming from TAC.
