Error: Unable to locate Javac Compiler in C:\JavaSDK\jre1.5.0_12\..\lib

[ptran]

Hi,

  I've to compile the PricingService project with Eclipse 3.3 and JDK 1.5 and I got this error:

-

---

Unable to locate the Javac Compiler in:

  C:\JavaSDK\jre1.5.0_12\..\lib\tools.jar

Please ensure you are using JDK 1.4 or above and

not a JRE (the com.sun.tools.javac.Main class is required).

I have got JAVA_HOME configured and also in eclipse's project properties's java built path. I also add the tools.jar in the path.

And I can see the Main class in there

Can anyone help me Thanks in advance

Are you sure that the C:\JavaSDK\jre1.5.0_12\..\lib is the proper path to your tools.jar?

I tried all the instructions in:

http://docs.codehaus.org/display/M2ECLIPSE/Project+FAQ

And all the related suggestions on various forums. Nothing worked.

Finally I removed all the JREs in my C:\ProgramFIles\Java - which is my JAVA_HOME. Now only the JDKs were available in JAVA_HOME - the error went away and everything started to work!

Looks like something in eclipse makes it pick the first JRE it finds in JAVA_HOME

Looks like something in eclipse makes it pick the first JRE it finds in JAVA_HOME.

Your JAVA_HOME environment variable should only point to one JDK installation, not to multiple. Typically it points to a JDK not a JRE.
