Tools jar does not exist Eclipse JAVA

Question

The archive: C:/Java/jdk1.6.0_26-32/lib/tools.jar which is referenced by the classpath, does not exist.

This is the error I have when run Tomcat. There was no problem cleaning or publishing - only when i start the Tomcat server.

Now, I checked my folders and there is a tools.jar in file path C:\Java\jdk1.6.0_34\lib

What am i missing?

using jre6 and have jdk1.6.0_34 installed

I found this question trying to build my project using Ant in Eclipse, and I would get the same error message as above. The suggestions in @Parth's and other answers to edit the Installed JREs is the first step. What I also needed to run Ant successfully was

1. Right click on build.xml, select "Run As", select "Ant Build..." (note the ...)
2. Click on the JRE tab
3. Change the Runtime JRE to the same thing that you updated in the first stage, and press Apply. (That is, the runtime JRE as you specified by "Preferences" -> "Java" -> "Installed JREs", as in @Parth's answer.)

Otherwise it seems that Ant will still try to build with the old JRE that doesn't have tools.jar. Hope this helps someone.

Right click on your eclipse project, In Preferences go to Java > Installed JREs, select your JDK and click on Edit. In the new Dialog you can add external jars like tools.jar to your execution environment.
