java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory

Question

I am using jdk 1.6.31 and when i add a server (WSO2 Carbon 3.0.1 based server) in eclipse and try to start the server it gives me the following error in the console:

java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
    at org.wso2.carbon.server.Main.<clinit>(Main.java:38)
Caused by: java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory

    at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
    at java.lang.ClassLoader.loadClass(Unknown Source)
    ... 1 more
Exception in thread "main"

WSO2 Carbon 3.2 based server gets started but with this in the console:

No properties path set - looking for transactions.properties in classpath...
Using init file: /D:/naveenraj/wso2/Training%20Workouts/wso2esb-4.0.3/lib/transactions.properties

Is this a vital error?

I am new to WSO2 ESB.

Can you run the wso2server.bat located in wso2esb-4.0.3/bin/ to start the server? Is it successful? Probable reason is that Eclipse can't determine some system variables. — Kasun Gajasinghe

What's the Carbon Studio version you are using? If you are not using v1.0.14, then update to it, and try. wso2.org/library/tutorials/2010/10/… — Kasun Gajasinghe

Am using The version you mentioned KasunBG ..Is there any problem if I don't use apache maven or ant ..Both of them are not installed...... — Naveen Raj

As of now I don't face any problems if i use the WSO2 Carbon 3.2 based server .....But there is only problem with the previous versions...I think we can ignore the WSO2 Carbon 3.2 based server based warnings....Can you solve the previous version problem..KasunBG — Naveen Raj

I'm not sure if this could help but make sure you defined JAVA_HOME and CARBON_HOME before starting the server

Good luck
