Problems with deploying third-party JAR (Can't find FAQ resource - link broken?)

Hi, 

I'm having problems deploying a third-party JAR to virgo, and getting an "java.lang.NoClassDefFoundError" issue. I've searched the forums, and found advice to read the FAQ on third-party JARs. I've found it at the following url:

https://code.vmware.com/article-detail/-/asset_publisher/8n011DnrSCHt/content/vsphere-web-client-sdk-faq

However, if I go to the link for "How to solve most java.lang.ClassNotFoundException errors?", the link is broken :(

Could you please let me know how I can access this information, as it is critically important to me at the moment.

Many thanks
