I have a WAR file with a web application that has been deployed to a weblogic stream.
The JSP part works fine, but it can't find the servlets. Possible due to the lack of mapping in my web.xml file.
I was working fine on Tomcat 6, but can't seem to find using weblogic.
I used annotation #WebServlet("/actionOne") but this doens't seem to work.
I am a little confused about how to map these correctly via the web.xml file.
the servlets are .java files and located at WEB-INF/classes/com/foo/bar/
So far I have added the following the web.xml file but the servlet-mapping section has me confused.
<servlet>
<servlet-name>actionOne</servlet-name>
<servlet-class>com.foo.bar.actionOne</servlet-class>
</servlet>
<servlet>
<servlet-name>actionTwo</servlet-name>
<servlet-class>com.foo.bar</servlet-class>
</servlet>
Hopefully the above is correct, the next section I'm not sure how to use and would appreciate some help.
<servlet-mapping>
<servlet-name>actionOne</servlet-name>
<url-pattern>/actionOne</url-pattern>
</servlet-mapping>
The servlets are being called from the jsp via a Form action="actionOne"
My mapping was correct, it seems the issue was related to a different version of servlet.api in the weblogic modules folder. 2.5 instead of 3.0. This resolved the issue.

I have the following problem:
In my web.xml I define how to serve pictures like so:
<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>*.css</url-pattern>
<url-pattern>*.png</url-pattern>
<url-pattern>*.jpg</url-pattern>
</servlet-mapping>
On Tomcat this works fine but on IBM Websphere 8.5.5.9 I get the following error:
"SRVE0303E: Servlet name for the servlet mapping *.css could not be found."
On another site I already found a solution for this issue (https://www.ibm.com/developerworks/community/forums/html/topic?id=5f4420ba-0754-43fe-8c87-91acc588d9fc) so I also created the ibm-web-ext.xml exactly the same as in their solution but the error still persists.
Does anyone know what I could do differently?
I found the answer to my problem, thanks to #MigratedPigeon because he got me thinking about the class of my default servlet.
A tomcat server has a default servlet, the class for tomcats default servlet is
org.apache.catalina.servlets.DefaultServlet
Websphere on the other hand does not have a default servlet, thats why I get the error "Servlet Name could not be found".
As in the answer I linked in the original question, static file serving can be activated by websphere by using the web-ext.xml file but that still did not solve the issue of my web.xml file having a "default" servlet.
In our application we use spring, so in the end I replaced the default servlet in web.xml with springs dispatcher servlet and now my web.xml file is valid for both, tomcat and websphere.
you should also mention this in your web.xml
<servlet>
<servlet-name>default</servlet-name>
<servlet-class>your servlet class</servlet-class>
</servlet>
Servlet mapping is done based on the value mentioned in the "" tags and respective servlet will be called.
We run an application written with "jspx" (Java Server Page with XML I guess), it runs on web-logic but the web-logic is down currently.
I wish to know if I could copy the files and put it under Apache tomcat.
I have actually tried that but I got some errors which makes me feel Apache tomcat is strictly for "jsp" and not "jspx".
If my assuption is right then what else can I use to compile a ".jspx" program aside from weblogic?
As far as I know, jspx are simply jsp files with well-formed XML instead of "just any html".
Try editing your tomcat/conf/web.xml and add another mapping for the jsp-servlet:
<!-- Existing mapping -->
<servlet-mapping>
<servlet-name>jsp</servlet-name>
<url-pattern>*.jsp</url-pattern>
</servlet-mapping>
<!-- New mapping -->
<servlet-mapping>
<servlet-name>jsp</servlet-name>
<url-pattern>*.jspx</url-pattern>
</servlet-mapping>
But... for Tomcat 8 this is already in place. Can you share the error messages you got?
I have deployed Myapplication.war in tomcat webapps directory.
now i have, index.jsp in $CATALINAHOME/webapps/Myapplication and process.class in $CATALINAHOME/webapps/Myapplication/WEB-INF/classes.
When index.jsp post some variables to process, http://x.x.x.x:8080/Myapplication/process
Im getting below err,
type Status report
message /Myapplication/process
description The requested resource is not available..
if i convert the process file from java class to jsp, im able to post from index.jsp to process.jsp.
How can i achieve this? any other settings i need to do here?
Thanks in advance
You'll have to declare your servlet in web.xml otherwise Tomcat won't know which class to associate with which path:
<servlet>
<servlet-name>processServlet</servlet-name>
<servlet-class>process</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>processServlet</servlet-name>
<url-pattern>/process</url-pattern>
</servlet-mapping>

A couple of minor niggles:
As per Java class naming, classes should start with an uppercase character, so it would be Process and Process.java.
Usually it makes more sense to put java classes into a package.
I'm trying to deploy a web service onto WebSphere using a WAR file, which I have been told directly is completely possible and has been done many times before. WebSphere allows me to upload the file, specify the context root, and even start the application. However, when I try to access it by specifying my underlying URIs, WebSphere 404s on me. The relatively useless error message displayed is:
Error 404: SRVE0202E: Servlet [Jersey REST Service]: com.sun.jersey.spi.container.servlet.ServletContainer was found, but is corrupt: SRVE0227I: 1. Check that the class resides in the proper package directory. SRVE0228I: 2. Check that the classname has been defined in the server using the proper case and fully qualified package. SRVE0229I: 3. Check that the class was transferred to the filesystem using a binary transfer mode. SRVE0230I: 4. Check that the class was compiled using the proper case (as defined in the class definition). SRVE0231E: 5. Check that the class file was not renamed after it was compiled.
I have checked my naming conventions, modified my web.xml according to this blog post, attempted packaging it into an ear file (which threw out its own errors when I tried to upload it), and am trying to figure out what configurations I might have wrong. Any ideas of what I could change to make this work?
Edit
Here is the relevant part of my web.xml file:
<?xml version="1.0" encoding="UTF-8"?>

</web-app>
Another Edit
I'm using the newest release of Jersey- is that part of the problem?
Yet Another Edit
I'm pretty sure that's the entire problem. WebSphere 6.1 runs jdk1.5, and Jersey stopped supporting that after Jersey 1.2...
As you suspect your problem is lack for WebSphere support for Jersey (or rather JAX-RS).
I don't see JAX-RS in the list of supported APIs by WAS.
http://publib.boulder.ibm.com/infocenter/wasinfo/v6r1/index.jsp?topic=/com.ibm.help.ic.WS.doc/info_sching.html
WAS 6.1 runs on J2SE 1.5 (as seen in the URL above)
Specification or API Version 6.1
Java 2 Standard Edition (J2SE) specification J2SE 5
These probably are the reasons behind the errors that you get to see in your WAS 6.1

I used to build my projects with maven. Now I want to do it 'manually'. But I struggle a little bit with directory order and other stuff. I first just created a new dynamic web project in eclipse and added JSF libraries. Now I tried to deploy a hello world page onto a tomcat 7. But jsf-tags are not getting rendered.
Here is my directory structure:
Anybody has an idea where the mistake is? Am I missing a library or is my structure wrong?
cheers
It finally works! thank's to balusc
But jsf-tags are not getting rendered.
This means that the FacesServlet isn't mapped in web.xml or you didn't make the URL in browser address bar to match the url-pattern of the FacesServlet. The FacesServlet is the one responsible for parsing JSF tags and doing all the JSF works.
Assuming that the url-pattern of the FacesServlet as definied in web.xml is *.jsf, then you need to open the start.xhtml by http://localhost:8080/fitnessverwaltung/start.jsf instead of http://localhost:8080/fitnessverwaltung/start.xhtml.
You can also change the url-pattern to *.xhtml, then you don't need to worry about this.
<servlet>
<servlet-name>facesServlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>facesServlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
