Hi,

I have Tomcat 6 with some web applications which run successfuly outside Myeclipse. But, if I run Tomcat 6 from inside Myeclipse, I receive a NoClassFound error for a class which I am sure it exists. Any idea, please

Best regards

Khaled

Khaled,
Can you make sure the connector looks like this:-
https://www.genuitec.com/forums/topic/tomcat-6-what-does-a-configured-connector-look-like/

Can you paste the entire error message here for me.

Also, can you go to MyEclipse > Installation Summary > Installation Details and paste the information here for me.

Thanks for the help.

My connector is correct. The entire error message is as follows:

Khaled,
You working with Apache Tomcat 6? Your error trace is showing Flex errors. an download another build of Tomcat 6 and test this again.

[dr_khaledcs]

Thanks.

I know it is caused by Myeclipse which can not load the class although tomcat is working correctly outside myeclipse. But, why myeclipse when it runs tomcat from inside can not load the flex class successfuly?

Best regards

Khaled

[Brian Fernandes]

Khaled,

Are you attempting to run the same instance of Tomcat from both within ME and outside?

When you say you’re sure the class exists, is it part of your application or is it in Tomcat’s common library location? It is also possible that when started externally, your startup script is augmenting Tomcat’s classpath, if this is the case, you need to make the same settings in the Tomcat 6 > Paths preference page.

Hope this helps
