Hello
Now it works.
What I have done :
1. check that no other application requires java JDK8 or JRE8
2. remove installation of java JDK8 and JRE8
3. install JDK7 (55) for 32 and 64 bits
4. install TOS DI in C:\TalendOpenStudio\
5. create TOS32.bat file to launch 32 bits version of TOS DI with -vm option to JRE7 32 bits version
TOS_DI-win32-x86.exe -vm "C:\Program Files (x86)\Java\jdk1.7.0_55\jre\bin"
6. launch TOS DI with the TOS32.bat
Launch of priorTest job : OK
beforeRunJobs :
1. modification of context :
root : C:\TalendOpenStudio\TOS_DI-Win32-r111943-V5.4.1\workspace\ESSAIDEMO32\documentations
workspace : C:\TalendOpenStudio\TOS_DI-Win32-r111943-V5.4.1\workspace
2. launch of the job : OK
Conclusion : TOS DI is currently not compatible with java JDK8
Hope it helps ...
