I have seen several postings, but no solutions for me.
Trying the above tutorial, at step 5, I get the error (from MyEclipse):

An internal error occurred during: "Generating JAX-WS Web Services".
Could not initialize class org.eclipse.wst.wsdl.WSDLPackage$Literals

Have tried to change Java version, but no luck.
I am running Version: 8.6

Error log msg:
An internal error occurred during: "Generating JAX-WS Web Services".

What am I missing (as a newbie) ?

lnadai,

I could not replicate it at my end.

Please copy paste your installation details here from the menu MyEclipse > Installation Summary > Installation Details.
I assume you have tried working with this tutorial. Right? :
http://www.myeclipseide.com/documentation/quickstarts/blueedition/blue_jaxws/

If no then send me the link for the tutorial which you are following.
Check if there are any specific errors pertaining to webservice logged in .log file which is at <workspace dir>/.metadata folder. Paste them here.

Thank you. Here is the info:

I know this is an old bug, but what was the resolution? I am all of a sudden getting this same exact error and was hoping to find a solution here. :( Do you happen to know what was the problem?

Greatly appreciated,
Anthony
