Tomcat HTTP 404 error - Requested resource () not available

lippy88

Hi,
Im working on my FYP and have got into huge bother at the moment...
Im working on a dynamic web project,it was fine yesterday and then today all of a sudden this error has popped up and I can not run my project in eclipse!:(
Ive searched up and down the net for an answer but to no avail! Any help would be much appreciated thanks as I have spent the last 8 hours pulling my hair out!

If you're hosting on Linux
Try /var/tomcat/logs or CATALINA_HOME/logs (where CATALINA_HOME is a path variabkle), also try your apache logs.
If windows, look in the running directory for the logs, or check the windows event log.

Tomcat is being asked for something it can't find.

Is it a jsp or a servlet or a html file?
Are you running tomcat from within Eclipse?

If so, one thing to do is to 'clean' the server and run again.

From the Server perspective, right click and select Clean.
Then run the webapp.

Sometimes eclipse<=>tomcat gets itself into a muddle.

Are you sure you are connecting to the right instance of tomcat?

Post the url and your web.xml file and we should be able to see what's going wrong.

Thanks for help guys,
This is the last file in the catalina log not sure if this is the one you are looking for:

Il just mention I also downloaded a pre-configured tomcat v6.0.28 from coreservlets.com, I dont think this could have anything to do with it though?
My environment variable is set to c:\apache2.0.28 and tomcat runs fine on internet explorer at address http://localhost:80 !! Ive noticed that other versions are http://localhost:8080 but 80 works for me.
The only other conclusion I can come up with is that when I set the settings for tomcat server in eclipse that I may not have correct!
Thanks again:)

This is whats displayed in the console when I run the project:

Ok, struts.xml is your problem. Post it up and we'll have a look

Thanks for your help Moycullen!:)

Giblet

Have you created this action?
<action name="checkJob" class="net.viralpatel.struts2.JobCheck">
<result name="SUCCESS">JobCheck.jsp</result>
</action>

Check for errors in that class as well.

lippy88

Giblet,
You are correct,my problem was in the JobCheck action class!!!:) In my action class I had declared 'public class Jobcheck' instead of public class JobCheck !!
I spent hours trying to figure this problem out and It never dawned on my to look at the java file as I was sure that this action would not affect the project starting up as it was not going to call the jobCheck action until a button was pressed on the web page!I thought it had something to do with the set up of my server...Thanks a million

moycullen14

net.viralpatel.struts2.JobCheck is missing?

Check that you have a java file for this and that it is compiled correctly.

Also, I'm guessing that you've copied this from a 'tutorial' on struts2 on the web?

Make sure you have all the JARs needed to run this in your WEB-INF/lib directory?

lippy88

Yes JobCheck.java had a spelling mistake in it, as I said I didnt realise this would prevent the start up of the web app as it wouldnt be used until asked to do so.
Anyway,seems the project is working ok again now thanks. And yes I found a tutorial online to help me start the base of my project: http://viralpatel.net/blogs/2009/12/tutorial-create-struts-2-application-eclipse-example.html
It was a handy tutorial and easy to learn especially since I was not very familiar with struts!

While I have you there Giblet you might able to answer one more question relating to a form for creating a new job.At the moment I have a number of textfields and then a drop-down list which displays the skills available to choose from. e.g java ruby sql etc. When I click submit, the form for some reason does not enter the data in the database.Im wondring have I named the drop down list correctly linked to skillName? I coded a print statement System.out.println(skillName); and when the action is run I get back : net.viralpatel.struts2.Skill@1bd9d76 instead of say 'Java'!

Here is the JSP of the form...

<s:form action="createJobs">

<s:textfield name="jobName" label="Job Name" />
<s:textfield name="startDate" label="Start Date"/>
<s:textfield name="endDate" label="End Date" />
<s:textfield name="salary" label="Salary" />
<s:textfield name="description" label="Description" />

<s:select label="Skill" name="skillName" list="skills" listValue="skillName">
</s:select>
<s:submit
</s:form>


Sorry for been a pain,taking up your time!

Giblet

It seems that skillName might be a complex type, not a string.

lippy88

Sorry I dont understand what you mean complex type?
I have set skillName as type String so I am trying to get the exact skill whether it be java / ruby back from the drop down list.

this.createJob.setString(7, this.getSkillName());
System.out.println(skillName);
