Currently the Java Development Kit goes by Java SE Development Kit. Java is notorious for using confusing acronyms in their product names. I had to edit the eclipse.ini file to reference the correct Java path -Įclipse doesn't use the environment PATH at all when there is a value in eclipse.ini. Step 1 - Install The Java Development Kit Red5 runs and is built on Java, the first step of setting up a development environment is getting the latest Java Development Kit. See " Java Downloads for All Operating Systems".Īpril 2016: Steve Mayne adds in the comments: I went to the Java manual install page (which was not as directly accessible as you'd like) and installed the 64-bit version. I downloaded Eclipse 64-bit which looks for a 64-bit JRE.īecause I didn't have the 64-bit JRE it threw the error, which makes sense. I'm running Windows 7 64-bit and I had the 32-bit JRE installed. Even though the default registered Java in Eclipse is the one used to launch the session, you can want to register an older SDK (including a non-Sun one) in order to run/debug your programs with a JRE similar to the one which will actually be used in production.Note: You could register just a JRE within Eclipse because it is enough to run your program, but again a JDK will allow for more operations.

You only need a JRE to launch Eclipse, but once Eclipse launched, you should register a JDK for your projects (especially for Java sources and debugging purposes, also in theory for compilation but Eclipse has its own Java compiler).

The JVM you will reference within your Eclipse session is not always the one used for launching Eclipse because:.

Copy any JRE of your in your /jre directory.

Reference that exact JRE path in your eclipse.ini.

I would recommend to always run Eclipse with the lastest JRE possible (to benefit from the latest hotspot evolutions).

"Installing" a JRE or a JDK can be as simple as unzipping or copying it from another computer: there is no special installation steps, and you can have as many different JVM versions (1.4, 5.0, 6.0.) as you want, "installed" (copied) almost anywhere on your disk.

Eclipse will by default try to launch with the default " java.exe" (the first one referenced by your PATH)
