Compiling servlet in Eclipse SDK

Why Eclipse cannot find javax.servlet.* and javax.servlet.http.*?
Here is a screenshot:

do you just want to compile it or deploy it on a server as well? compiling usually isn't the problem, since it's just a simple class as any other.
if you want it assembled as a deployable web-application you will need ant (war-task) or a plugin like lomboz or myeclipseide to do that for you.
hope that helps.

How to compile and run servlets in Eclipse?

Does somebody known how can I compile and run servlets in Eclipse IDE? I've added and configured Tomcat's plugin. I've created a project with my example servlets source, and I don't know what farther. How do I have compile it without main method? I must add web.xml file from Tomcat's directory into projects in Eclipse and modify it?

Try googling for "eclipse servlet", surely someone has written instructions.

Can't get Eclipse 3.3 to compile servlets

Hi,
This is my first time tyring to compile a servlet in Eclipse 3.3. I have serveral errors like "Can not resolve import javax.servlet..." I did include the location of the servlet-api.jar file in my classpath. And not just classpath but I included the location to variables PATH, JAVA_HOME just in case but still no luck. I have browsed the web enough, and tried all the tricks of the trade. I am using jdk1.6_02 and tomcat 5.5.25.
Can anybody help,
Thanks in advance!

Okay, let's start simple: An instance of Comparable<T> can be compared to instances of T (for any type T). Lets assume Numbers were Comparable:
class Number implements Comparable<Number> { /* ... */ }
class Integer extends Number { /* ... */ }
class Float extends Number { /* ... */ }This means an Integer can be compared to any Number, such as a Float or another Integer:
Integer ten = 10;
Integer five = 5;
ten.compareTo(five);Now let's write a generic function that can sort lists of items that are comparable with each other:
public static <T extends Comparable<T>> void sort(List<T> list) { /* ... */ }If you tried to pass a List<Integer> to sort, you would essentially substitute Integer for T, however Integer does not satisfy the upper bound of Comparable<Integer>. If we substitute Integer in the declaration you provided in reply 2
public static <T extends Comparable<? super T>> void sort(List<T> list) { /* ... */ }we get an upper bound of Comparable<? super Integer>. You're free to substitute "? super Integer" with a supertype[1] of Integer, such as Number and since Integer implements Comparable<Number> the substitution is valid and the call is legal.
Generics are all about substituting.. ;)
To answer the question of what does T extends Comparable<? super T> mean: It means you may substitute any type U for T where U is comparable to a supertype[1] of U.
With kind regards
Ben
[1] the super- and subtype relations are reflexive, in other words Integer is a supertype and a subtype of Integer.

Trying to run my first servlet through Eclipse + XAMPP

I'm trying to run my first servlet through eclipse, I'm using XAMPP + Tomcat add-on as my webserver. How do I even try and compile my servlet? I've added the external jar Servlet-api.jar to my project as stated in here, http://www.theserverside.com/discussions/thread.tss?thread_id=37924
But eclipse wouldn't compile it, because there just isn't a main() in my servlet program..
Do I need to install the WPT plugin for eclipse? I'm guessing I'm not setting my CLASSPATH correctly - Do I need to set it up manually?

Nevermind, there were lots of Issues going the XAMPP way, so I just installed Tomcat separately and all is fine now.
I used instructions from http://www.scribd.com/doc/495993/Installing-Apache-Tomcat-6-and-Using-It-With-Eclipse and it was a walk-in-the-park..

Unable to compile application in eclipse

Please help me compile and run a servlet HelloWorld project in Eclipse.
I am trying to compile a sample helloWorld Servlet in Eclipse 3.x Europa and Tomcat 6. When I click on Run a window comes up asking do I want to run it as a java application or Applet. If I selet Applet, it said that there is no applet avaible. If I select Java Application is will ask to select an item from the list. The following three items appeasr in a list
jspC �
SDCInstaller -
SmapGenerater �
If I go to projec to build the class, it is grey out. However, the option Build Automatically is checked.
If I look in my working directory, I can see a blank bin, src, and work folder. In the WEB-INF directory, I see a empty lib, the scr has the HelloWorld.java, and the class has the Helloworld.class. Please Help me!!!

Thanks,
I was able to compile it. First, I start tomcast, and I stop it right away. Then, I click on run, and it run it. However, I am getting the error message. I think it may have to do with the xml file that I am using. I notice the web-app and servlet name are hilight as if they were spelled wrong. If I change web-app to WEB-APP, it does not show me the error but it does not work either. Below is a copy of my web.xml file and the error message that I am getting when I type the url http://localhost:8080/HelloWorld/hello

Unable to compile servlet files in javac

i am unable to compile servlet *.java files in javac.as far as i can see my path is correct.
Kindly provide a solution as soon as possible.
My jdk1.3 is in my c drive and my tomcat in my d drive.
if you are able to compile kindly let me know your path.
it says symbol not resolved.i think that it is unable to import from javax

Assuming that your jdk is in c drive as c:\jdk1.3 set the path and the classpath like as shown below. Remember that you have to set the classpath for the classes in the javax.servlet and javax.servlet.http packages. I know how to do it for JavaWebServer. JavaWebServer has a jar called servlet.jar that contains all these classes. What you need to do is to put this jar file in your classpath. There will be a similar jar file for Tomcat server also. You need to refer the Tomcat server documentation for that.
The path and the classpath have to be set like this...
d:\>path=%path%;.;c:\jdk1.3\bin;
d:\>set classpath=%classpath%;.;c:\jdk1.3\lib;c:\JavaWebServer2.0\lib\servlet.jar;
assuming tht JWS is installed in c:\JavaWebServer2.0
Also note that there should be no spaces in between while setting the classpath. In your case you have to change the last part of the classpath to customize your requirement.
Hope that will help.

Jaydeep

Not Able to compile Servlet from ?

C:\CC4\prog\jakarta-tomcat-4.1.30
as per above setting servlet should be compiled but still i m getting error message:

Getting error in compiling servlet

there are 6 error almost same not resolve servlet or http. I already add jdk1.3.1 and tomcat in my path I don't understand why I am getting this error please help me.

You need to add servlet.jar into the classpath. You can find servlet.jar in tomcat_home\lib dir.

How to run Servlets in Eclipse

Am trying to run a servlet in elipse...but when i do so, the file which is am runnig is getting downloaded in my browser....
What should i do.....

You can't. You can only run it in a servlet container. There are plugins which allow you to easily deploy to and control a servlet container from within Eclipse, and some people mistake that for "running a servlet in Eclipse" but you'll have to learn how to deploy to a container at some point, so you may as well do it now. Once you know how to do that, google for "j2ee eclipse plugins" and you'll get loads of hits, some of which are even useful

How to run a servlet in eclipse using "SAP Portal Plugin" ( not tomcat)

Hi All
I'm just trying to create a simple servlet in Eclipse using SAP Portal Plugin but I couldn't find any document.
I have an eclipse 2.1
EP6 SP2 patch 5
SAP Portal Plugin
I created a Portal Application Project.
I created a simple servlet and save it under src.core directory.
My question is as follow:
1) Which directory I should put in the file web.xml?
2) Do I export this as *.par file?
3) When I export it. Can I just call the servlet from the url?
Anyone help.. I really appreciate.
thanks much.
Jen

Hi,
Portal plugin is used for developing SAP Portal applications ie Java iviews.
There is a set of procedures to develop Java iViews . You can develop either AbstractPortalComponent which is more or less equivalent of servlet in ordinary java world or JSPDynPage which is equivalent of JSP.
These plugins are used to develop any of the above portal components. If you are developing java applications for portal then you have to develop either of the above using the tools. These portlets( portal applications runs on Portal run time)
But servlets can run on J2EE itself.
But if your requirement is to develop servlet then you can create ordinary java project and deploy that in the J2EE server as like in any app server.

Compiling servlet with helper class

Hello,
I have to write a very large number of database queries and huge amount of code so I decided to make each helper *.class file for each table.
Now I have a main servlet that should instantiate each of these helper classes and conduct DB operations:
//Servlet code
RescardreservationTable rv = new RescardreservationTable();
rv.insertInfo();
RescardPassengerTable rp = new RescardPassengerTable();
rp.insertInfo();RescardreservationTable.class
//does DB opsMy problem is that when I try to compile servlet, I get
insert_data.java:172: cannot find symbol
symbol : class RescardreservationTable
location: class insert_data
RescardreservationTable rv = new RescardreservationTable();
Could somebody please tell me how I can make servlet locate my java classes that it has to use?
Thanks,
Victor.

Ok, looks like it's solved. Just forcing the compiler with -classpath to look for the required class file.
