mkyong.com is a popular Java related tutorial website. Although you may not find a lot of Websphere topics in his site, or in the menu, he actually has some Websphere tricks hidden in his sleeve. There are only four entries for Websphere so far. I give you the topics below.
1. Remote Debugging with Eclipse + WebSphere 7
2. How to increase WebSphere JVM memory
3. WebSphere 7 & javax/persistence/OneToMany.orphanRemoval() error
4. Metro on WebSphere 7 – com.ibm.xml.xlxp2.jaxb.JAXBContextImpl incompatible exception
