Detection of local JVM only finds the Oracle Java

Post by Paul Gellissen »

Hi,

I would like to know how OWS searches and detects the locally installed JVM.
This is due to the problem that an installation of jre-8.0.242.08-hotspot from AdoptOpenJDK never gets found.
But when I define the installation path manually the installation gets found.

Hi,

On which Operating System are you running the OWS Settings tool to look for local JVMs?

we basically search the most common path. If you tell us where adopt is installed we can take this path into the list for the next release

Hi,

with the settings left on standard it gets installed to C:\Program Files\AdoptOpenJDK
At least when I scan with this folder the JVM gets found.
It was tested on Win10 1909x64.

On Windows OWS searches in :
1. "Program Files (X86)\java" and "Program Files\java\"
2. <Cygwin/Home>/.sdkman
3. "Program Files (X86)\Amazon Corretto" and "Program Files\Amazon Corretto\"

In a future release we can add to the search path Program Files\AdoptOpenJDK and Program Files (x86)\AdoptOpenJDK if as you say it is the default.

Hello,

Hope this is an appropriate thread to report this topic. I have AdoptOpenJDK 8 runtime and OpenWebStart installed on both Windows 10 and macOS Catalina at their default install locations. Locally installed JVMs do not get detected by OpenWebStart automatically; Why so? I need to explicitly click Find Local to do get them configured. Why isn’t this a default behaviour without user requiring to do an additional step to detect JVMs?

Thanks,
Vijayasri

Hi Vijayasri
We explicitly designed it this way because many of our customers provide a JVM download server which offers specific Java versions for their applications.
If OWS would automatically detect and use any locally installed JVM then such a JVM may take precedence over the one from the download server.
