Validator.java:23: non-static method equals(java.lang.Object) cannot be referenc
ed from a static context
[javac] return EditEventModel.equals(clazz);
[javac]
The equals method cannot be used as a static method. That is, you need to provide an object. Try EditEventModel.class.equals(clazz);
Validator.java:68: cannot find symbol
[javac] symbol : variable lang
[javac] location: class com.teradata.portlets.calendar.validators.EditEventV
alidator
[javac] if(obj.getClass() == java.lang.String && ((String)obj).trim().len
gth() <= 0)
I would try obj.getClass().equals(String.class)
Thanks! I'm well on my way to getting this thing running. Do you know where I put these folders? Images, Incudes, js, resources and tooltip? I shuffled all my folders and I have no idea where they go.
These folders go under yourProjectName/web/
Ok. I deployed the project but when I try to add the portlet to the portal all I see is the loading bar. Before I had the folders in the right place my portlet was under a different tab but now its Undefined. Maybe the folders are still the problem?
Anyone know how to fix this error?

You can just redeploy the portlet and this shouldn't be an issue.
You can also manually undeploy the portlet by going to _$CATALINA\_HOME/webapps_ and _$CATALINA\_HOME_/work_ and removing the files/folders related to your portlet.
I redeployed and I still get those errors.
Did you try manually undeploying it?
Yeah, I deleted the files for it in those directories. This is what Tomcat is displaying.

That is not the same error, it tried to deploy, but there was an error with the portlet. There is probably an error in the code that prevented the portlet from deploying successfully. You will need to take a look at the stack track (look for the ERROR line with a Java stack trace) to determine why it failed to deploy.
How do you do a stack track?
You posted part of a stack trace on the other page; it's the message the explains the reason for the error with a track through the source code stack. Please post the whole trace.

Is this what Tomcat is displaying when you start up, having already removed your portlet?
Yes
Actually, I fixed this problem. I should have edited that a while ago. Sorry.
I don't know how to fix these errors. I'm not really sure what the first one wants but I'm pretty sure the second one just can't find that location so how do I fix these?
