First I created a Java App to test my code to contact the NXT Brick using Bluetooth. Once this worked I created a Webservice instead which should connect to the NXT Brick through Bluetooth.
This is where the problems start. My Webservice works fine, I can see the services and I can invoke them.
One service uses NXTComm, which is in the Lejos PC Libraries (lejos.pc.comm.NXTComm). I've added these libraries to the project and I've added "import lejos.pc.comm.*;" at the top of the class but I still get the following error.
[ERROR] lejos/pc/comm/NXTComm

Why can't the services get to these libraries and what should I do to fix this?
So what have you done in order to add the leJOS libraries to your web application? Why would you expect, that they are in the classpath?
It might work, if you but the JAR files from the folder lib/pc in your leJOS distribuion into the WEB-INF/lib folder of your web application. Alternatively, there is a directory for libraries that all web application can access. It must be located somewhere where Tomcat is located.
BTW: The system property java.class.path does not really return the paths that are searched for classes. If one is using classloaders (which tomcat does), the paths they search are not present in java.class.path.

i have a spring mvc project in eclipe spring tools suite IDE and i wanted to add some classes from a WSDL, i try using maven-jaxb2-plugin but it dont do nothing when i update my project using maven. So i try to create a web service client in eclipse and in the service definition i put my WSDL url but after a few seconds loading it gives me a Invalid segment definition, after all this i try creating a Java Application Project in Netbeans and then add a web services client in that project with my WSDL url this time it worked!, so i try to add the .JAR file of that project that locates in D:/Users/myUser/Documents/NetBeansProjects/ImportClassesFromWSDL/dist/ImportClassesFromWSDL.jar
i added this jar as a external JAR following this steps How to import a jar in Eclipse , the .JAR was added but i have this warning
Classpath entry D:/Users/myUser/Documents/NetBeansProjects/ImportClassesFromWSDL/dist/ImportClassesFromWSDL.jar will not be exported or published. Runtime ClassNotFoundExceptions may result. WSproject P/WSproject Classpath Dependency Validator Message
in the eclipse text editor i can write with no problems the name of the classes and create objects of this classes with no problem, but at the moment when i run my project and get to the part when i create this objects from the imported classes i get a class not found exception

I got this to work, I copied the .jar to my WEB-INF/lib directory.
Thanks for #Arkantos who suggested it.
I am working on a Java Dynamic Web Project in Eclipse. Everything was running smoothly until I realized that my package names were uppercase, and decided to change them.
After changing them, I am getting ClassNotFoundExceptions at runtime. The code compiles fine. From what I understand, this is a runtime classpath issue.
The error is shown here:

Here's a screenshot of my folder structure:
http://imgur.com/VJvJbeb
src/Controllers and src/Model were the packages I switched to lower case. I switched them back hoping to resolve the issue, but to no avail.
I tried checking my runtime classpath for the project by going to Run --> Run Configurations, but the project isn't listed there.
Here is a snapshot of my Web Deployment Assembly:
http://imgur.com/D0rg2aZ
Does anyone know how I might go about fixing this? Any help would be greatly appreciated.
Solution Found
Thanks for responses everyone. Thankfully I managed to fix the issue by:
Right clicking the project folder ---> Build Path ---> Configure Build Path
Navigating to Source tab
I saw that the default output folder was "WorkTicketSystem/build/classes." I switched this to "WorkTicketSystem/WebContent/WEB-INF/classes."
And, voila. I'm not exactly sure why or how my actions fixed the problem, but if anyone could explain I would be very interested to hear it. For now I am just happy that it runs.
In your web.xml, you have a reference to the class Model.Converter. You need to change this to model.Converter.
If we change the package name to uppercase we have to check whether all references with that package got modified or not. As you are saying that if you try to run package names with lower case is working fine. If you try to modify the package names with IDE that will ask for updating references also. Once check that.
NOTE: *As per java coding standards package names should be in lower case.*
I have created the JDBCSQl.java, which is basically get one value from database. As standalone it is working fine.
When I call this class within another Servlet Java programming, null value is getting returned.
I've checked the trace log of database, it is not querying a statement at all.
I am getting the error below, when i execute. Both JDBCSQl.java and Servlet.java exists in in a single package of project.

Add sql server jdbc jar in your web apps lib folder and then try.
I have deployed a Struts 1.3 web application in Apache Tomcat 7.0.41. The tomcat server seems to often hang & fails to process any request showing the page not found error on the browser resembling a stopped tomcat server, but actually in the Windows Services the tomcat service is still shown as Started. The server works fine after a restart.
The following error was logged in Apache Software Foundation\Tomcat 7.0\logs\tomcat7-stderr.2013-07-05.log

The web application does contain some forms that have Struts 1.3 FormFile elements that are used to upload files to the server. The application worked fine in Tomcat's development mode that is configured in MyEclipse IDE. It seems that File Reaper thread is the culprit or is it? How to fix or handle this issue?
Regards,
Shiva
You should configure the database settings to run with the Tomcat server. There's unknown from your post configuration but I guess that you just didn't include database drivers with your application, or the database drivers aren't installed at Tomcat sever.
I have this application on Websphere Application Server 7.0 that I am in process to port to tomcat 7.0.2.
I have following line of code in my application :
parameters.remove("MainUserId");
parameters.remove("MainPassword");
This code gives me the following exception on Tomcat

Basically here parameters is a session parameter map. So as per java specification parameters map is immutable. But this works good for Websphere Application server.
While researching, I read a comment here that says
if this worked in WebSphere then WebSphere is not following the
specification. Either because of a bug or because it has been
explicitly configured to ignore that part of the spec.
Any alternatives? except do not remove elements from map
Also, is it possible if there is any configuration in tomcat that can make the parameter map mutable ?
