Hi,
I have simply question, where i can check what version of jdk,jre i shoud use to compile my project using Plain Java Api. Im not sure but version of jdk/jre is dependent on the version of RTC. I think correct? |

A good hint is the version of Java that ships with the RTC version. I have used Java 1.5 in the past and now use Java 1.6 and it worked fine. I have seen issues with older versions that did not support generics.

Hi Robert,
I haven't seen an explicit description of what version of the JRE you should use. I use Java 6 and it works fine. If you haven't seen this, it may help you get started: https://jazz.net/wiki/bin/view/Main/RTCSDK20_DevelopmentEnvironmentSetup. |

Please use the JDK that ships with the server if you get issues with other JDK's.
Please accept answers if they are correct.
Please consider to open a new topic instead of adding to a fairly old one. You can add a link to the old topic.
