Java JDK Version

[tmac]

The "About MotiveWave" is showing Java Version 23.0.1.

I've been using Java JDK 21 with Eclipse to code studies. Should I be using JDK 23 now instead?

I don't believe it is critical. You should be fine with 21.

Hi good folks... in lieu of starting a brand new thread on this, any idea which version of JDK works with version 7? Version 7's "About" says 24, but right off the bat I got a failed build when run as Ant 1 of the build.xml as prescribed in the environment set up page: https://docs.motivewave.com/user-guide/sdk-programming-guide/environment-setup

When digging in, I'm finding mismatches and missing elements between what's in the online API documentation for version 7 and what's available in the Motivewave SDK's jar. I tried JDK 17, and that didn't work either. Many thanks in advance for the guidance!

I'm using JDK 24 with what SDK for Beta 7. I have noticed that some things don't work. Compiled and ran in V6, updated the sdk/jdk and recompiled without errors. However, the code doesn't work in some instances. Hoping it is just a beta thing.

I upgraded few studies to Version 7. It got compiled with java 24. Any specific errors you are getting?

Hi, are you saying that you compiled the studies with Beta 7 SDK and ran that in motivewave version 6? If that's the case, then they have stated it won't be backward compatible. Studies compiled on sdk version 7 won't run on previous versions of motivewave.

Would you mind telling me what things didn't work? just for reference.

Hi John; many thanks for chiming in!

I never installed MW6; just 7. The errors were numerous; after wrestling with it for a bit, I ended up deleting the project and all my records of it, and so I'm afraid that I can't provide any of the specific errors. But I never got to the build stage; the project was infected with errors even before the build, notwithstanding different JDK installs, a switch to IntelliJ from Eclipse, and various configs of the IDE and project.

My goal was to port a few of my custom Tradingview Pine Script indicators to Java for use in my MW set-up, as I'm switching from TV to MW. But I'm honestly not good with Java, and so I decided to back away from the notion of DIY and look to engage someone with MW Java dev experience.

Both the JAVA and MW-SDK learning curves can indeed be steep.

There is, however, help out there
