Hi support,
Been researching for hours now on this issue and have searched the MyEclipse forums, but found nothing relating to my issue.
I recently needed to upgrade to Java 1.6. Problem lied in updating Tomcat’s JVM within MyEclipse to Java 1.6.
When I ran Tomcat outside of MyEclipse (using Configuration Manager) I was able to change the JVM to Java 1.6. This worked fine and the manager reported the JVM being 1.6.
In MyEclipse IDE I changed the installed JRE to 1.6. (Window > Preferences > Java > Installed JREs. It now points to “C:\Program Files\Java\jdk1.6.0_02”.
When I ran Tomcat through MyEclipse, I then went to the Tomcat manager (locahost:8080/manager/html) and it reported it was using Java 1.5’s JVM, not 1.6.
I then decided to delete all other Installed JREs from MyEclipse and now Tomcat is not working at all. When I run Tomcat I get this error:
A configuration error occurred during startup. Please verify the preference field with the prompt: Tomcat JDK name
I then get a link of “Show preference page” which takes me to the following screenshot:

I do not see anything wrong here with my Tomcat setup.
Additional info:
Apache Tomcat version 5.5
MyEclipse Version: 7.1.1 – Build id: 7.1.1-20090310
Java 1.6.0 Update 02
I would appreciate any advice or help with this, as I am completely stuck.
Thanks in advance.
