We are running windows 8.1 with both java 1.8.0_77 32 and 64.

If we don't force to start with c:\program files\java\jre1.8.0_77\bin\javaws.exe, the webpplication starts by default in 32bit.

If we use a Xmx bigger than 1G the jnlp starting fails. we tried adding -d64, -J-d64, but nothing was successful. We cannot remove the 32bit version.

Is there a way to force to start jnlp with 64bit java version?

  • Maybe changing the default `JNLPFile` file association to launch the 64bit java webstart app? The use of the 32bit JRE is pretty much determined by this registry entry. – Anya Shenanigans Apr 20 '16 at 13:51
  • I already did this try... I don't know why this is starting with the 32b version. I doesn't make sense. – Nick Apr 21 '16 at 05:48

  • Hi, my environmental variable is poiting to C:\ProgramData\Oracle\Java\javapath in which there are 3 symbolic links pointing to the 64 bit java version. – Nick Apr 20 '16 at 12:41
