Solution to the problem that java eclipse cannot be opened

This is a problem where the JDK is not configured properly. The solution is as follows:

Run CMD.

Enter java -version to see if there is any version prompt? If there is, it means your JDK is correct, then it is an Eclipse problem. There is no reference to other methods.

1) If not:

Click: "My Computer" - (right-click) "Properties" - "Advanced" - "Environment Variables" to pop up the "Environment Variables" of Windows Configure the card.
Perform three operations under the "System Variables" column:

①Create "Java_Home", value: the absolute path where the JDK is located (for example, D:\Program Files\Java\jdk1.5.0_04\) .

②Create a new "Classpath" (if it already exists, edit it directly), value: .;%Java_Home%\lib (if there is original content in the value, separate it with a semicolon).

③Create a new "Path" (if it already exists, edit it directly), value: %Java_Home%\bin; (If there is original content in the value, separate it with a semicolon).

Or

CLASSPATH

C:\Program Files\Java\jdk1.6.0_03\lib;E:\workbench\lib\javax. servlet.jar;

JAVA_HOME

C:\Program Files\Java\jdk1.6.0_03

Path

%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\Microsoft SQL Server\90\Tools\binn\;%JAVA_HOME%\bin;
