But there's a catch: Windows has to know where it can find these programs. You can execute programs from a Command Prompt by simply typing their names, such as javac or java. The (not all that) hard part: PATH and CLASSPATH The reason for this suggestion is that the next steps in the installation process will be simpler if the folder you choose has a shorter name that, importantly, has no spaces in it.
#ECLIPSE OS X NO JAVA VIRTUAL MACHINE INSTALL#
(And, of course, you can feel free to install to a drive other than C:, if you have more than one.) I suggest changing it to the following folder instead:
When asked what folder you should install the JDK into, the default will be: However, after running the installation program, you still won't be able to execute javac or java, without making a couple of modifications "under the hood" of your system. The JDK includes an installation program, which places all of the files into the appropriate places and sets up some shortcuts for you.

It's best to download the JDK and not the JRE - the difference is that the JDK includes a Java compiler ( javac) and a variety of other tools for building and packaging-up Java programs, while the JRE (the Java Runtime Environment) includes only the necessary tools to allow you to run Java programs. A great option is to download the Java SE 7u5 JDK (JDK 7) from Oracle's Java SE Downloads page. What you'll need to get started is a Java compiler and Java virtual machine, both of which must support Java 7. (Use the "Add/Remove Programs" utility in the Windows Control Panel to uninstall Java delete the "eclipse" folder to delete Eclipse.) Leaving old versions causes setup of Java 7 to be more complicated and problematic, and an old version of Eclipse will not recognize the new version of Java without some rather messy settings changes, whereas installing Eclipse after installing the new Java will cause Eclipse to find and use Java 7. Removing Eclipse and previous versions of Javaįirst, it's best if you delete Eclipse and uninstall all earlier versions of Java you have installed on your machine. It is a bit tricky to install properly read the directions of the site carefully. The version you want is at this link in particular:
#ECLIPSE OS X NO JAVA VIRTUAL MACHINE MAC OS X#
If you want to run Java 7 under a version of Mac OS X prior to 10.7 (Lion), there is a version from the OpenJDK group available at. Installing on Mac OS X versions older than 10.7 (Lion)
#ECLIPSE OS X NO JAVA VIRTUAL MACHINE UPDATE#
If you use Linux or Solaris, JDK 7 Update 5 can be downloaded from Oracle's Java SE Downloads page, the same way it can for Windows, and can also be downloaded using built-in "package managers." Installation procedures vary from one distribution of Linux to another, but ample documentation is available online. To install Java 7 and Eclipse on either of these operating systems, see the applicable section below.
#ECLIPSE OS X NO JAVA VIRTUAL MACHINE HOW TO#
If you do, you're asking for trouble.Installing on Windows or Mac OS X 10.7 (Lion)īefore you get started, be aware that this document only describes how to set up Java 7 and Eclipse on a computer running Windows or Mac OS X 10.7 (Lion). It is also inadvisable to remove the -vm or Xmx options. Also note the See Also links at the bottom of that page for more details about things like heap size, etc.ĭO NOT delete eclipse.ini, EVER. Some of these hacks might work temporarily or on certain machine configurations, but the contents of eclipse.ini are not trivial nor arbitrary.įor the authoritative reference, see this : that explains the contents of the file. Most of the advice in this thread is misguided.
If the above fix is not fruitful, then do not attempt anything else. *there is no dquote for path, and path points to right java version folder mentioned in ini file*/ The proper solution to your problem is to add the -vm line pointing to jvm.dll file of your Java folder in ini fie.Ĭ:\Program Files\Java\jre1.8.0_202\bin\server\jvm.dll Why can I not use '1024m' for '-Xmx' and '-launcher.XXMaxPermSize'? Reducing -Xmx to 512m also fixes the issue. Removing the value 512 of -launcher.XXMaxPermSize fixes the issue, but it causes permgen errors
Removing -launcher.XXMaxPermSize fixes the issue, but it causes permgen errors My JAVA_HOME is correctly set as far as I can tell. I am getting this error message when I start Eclipse Helios on Windows 7:įailed to create the Java Virtual Machine
