I am having a problem with the jsp editor. I am going through the Struts quick start tutorial and get to the point where userLoginSucess.jsp has to be edited and saved. When I try to open the file I get the following message.
java.lang.NullPointerException

Any suggestions or work arounds would be appreciated.
Cheers,
SteveCan you switch to a brand new workspace, create a new project and try working with the JSP file to see if the errors go away.
I created a new workspace and tried to create and edit a jsp and got the following error:

SteveAre you using the Full Stack installer to setup MyEclipse ? I doesn’t seem like you are. Can you download the MyEclipse Full Stack installer from the download page and use that to setup MyEclipse. It includes the JRE, Eclipse and MyEclipse all pre-integrated and optimized to run together and you won’t have to mess around with any installation problems like you are having right now. It’s the fastest way to get you up and running with a clean install.
Thanks for your help. I downloaded the fullstack version 6.0 package and eveything seems to work ok now. I will now purchase the product.
Keep up the good work!
Cheers,
Steve
