I'm following the instructions to upload the files to the server, but only the JSP is displayed. When I check for the servlet, I know it's uploaded because I can see the file if I type .java at the end, but it's doesn't give me access when I just type the URL we are supposed to do. Any tips?

Did you also upload the web.xml file ?

No, but the xml shouldn't matter when it comes to display the servlet

What about the URL mapping, did you name it appropriately when creating the servlet.

Yes the directories are the same ones as the ones he told us to do, but it doesn't display the servlet. The only one working so far is the JSP

I think you uploaded the wrong file because you said you can see the .java file. The folders we need to upload are WebContent and class and none of them contain any .java files.

I followed exactly what the instructions said to upload it to the server. I don't think I uploaded the wrong file. If any of you uploaded it already, can you send me the link to it so I can look it up?

the class folder should have had another folder in it (the name depends on what you called the package) and the .java file should be in there. For OP you do need the .xml file or it wont work. Also make sure the the compiler your using is jre 1.7 and not 1.8 or the server wont run it (i had this problem - i had to redo the whole project to get it to work right then reupload). and like MBARRA10 said, make sure the mapping is correct. What is the URL that displays at the top when you click on the link on the JSTL?

I could be wrong, but shouldn't the files under build/class be .class files instead of .java files? Since .java is the source code and .class is the binary.

Make sure you are using version 1.7 for your java compiler. I had the same problem for the servlet and it turned out it was the compiler.  

Right click your project-> properties-> java compiler

yea, I know. I want to see whether you have the "/lab2/" part before the servlet in your url. If it doesn't, I might know what's going on.

I'm pretty sure there's a Mac version of WinSCP that you can download. Use it. It's more organized and clear and it really helps you in knowing which files and folders you have to retrieve files from and/or upload to.

Really the only thing I can think is the url mapping.. whats the name of the package? If its cs320.lab2 or something then under classes its supposed to be "/WEB-INF/classes/cs320/lab2/HelloServlet.class"

yeah that's the package name I have. I used to have it like that online too, but it didn't work, so I changed it to the way the other guy had, but still didn't work

Please confirm that you uploaded your .CLASS files, not the .JAVA files.  

Next, confirm the URL mapping that is specified near the top of your HelloServlet Class definition in HelloServlet.java.  What is the mapping specified?

Next, which package is the Servlet defined in?

Lastly, confirm that your web.xml file has been uploaded to WEB-INF.

Here I attach a photo of the mapping at the top of the HelloServlet.java

the package for the servlet is cs320.lab2

The professor is talking about the cs3 server, when you uploaded the Servlet, are you uploading the HelloServlet.class or HelloServlet.java? (Supposed to be the class one)

Yes I had fixed it, but he told me that I couldn't have an external file with the HTML so now that I modified the .java and uploaded the class, I get an error. I get this even though the servlet has the html code already in in

First I thought that it would be nicer and cleaner to have an external html with the servlet html so that I wouldn't have to have all the printout lines, so I did it like that, but the professor told me not to do it like that, and now that I changed my servlet class, it doesn't let me display it. I always get that damn error

I'm confused by what you mean with external html........ Anyways, what does your HelloServlet link look like?

Okay I fixed it already. My friend had the same problem, but somehow he figured it out, and he helped me with it. I just had to change the name of the package, then delete everything from the server and reupload it again so the .class will rebuild. It's a pain in the *** the damn server lol, but thank you everyone that replied and helped :D
