I configured Eclipse WTP for a struts-enabled web application. When I ran
my application using "run on server" option, it gives a 404 error.
Below is my configuration:
Java - 1.4.2_13
Tomcat 5.5.23 with Java 1.4 compatible jars
Struts 2.0.6 with Java 1.4 compatible jars
Eclipse WTP 3.2.2
I created a new "dynamic web project" with Tomcat 5.5 as runtime, "r5sis"
as "context root" and "WebContent" as "Content Directory". I copied the
struts jars to the "WebContent/WEB-INF/lib" folder. The jsp files are
placed in "WebContent/WEB-INF/jsp" folder.
Find below my struts.xml and web.xml
<?xml version="1.0" encoding="UTF-8"?>
<struts>

When I run the application by using "run on server" option, the tomcat
server starts without a problem and opens the url
"http://localhost:8080/r5sis/" in the browser.
It gives a 404 error, saying "The requested resource (/r5sis/) is not
available." "r5sis" is my project name. Also the project is placed only in
the eclipse workspace and not in the "<tomcat dir>/webapps" folder. Even
"localhost:8080/index.jsp" gives a 404 error.
When I tried running Tomcat from the command prompt, it runs properly and
"localhost:8080/index.jsp" works fine.
So the Tomcat is not working fine inside Eclipse WTP. Please let me know
what went wrong.
Thanks

When you create a Tomcat server within WTP, it will default to creating
a separate server instance, rather than "take ownership" of your Tomcat
installation. To see where the separate instance is found, double click
the Tomcat server in the Servers view and in the server editor that
opens, click the "Open launch configuration" link. In the launch
properties dialog, select the Arguments tab and note the setting for the
catalina.base system property in the VM Arguments field. You can have
the server in Eclipse use your Tomcat installation as the server
instance by unchecking the "Run modules directly..." check box in the
server editor and saving. Be aware that changing the server instance to
the Tomcat installation means the configuration files found under the
Servers project in your workspace become the "master" files for this
Tomcat installation. They will overwrite those in your installation
each time the Tomcat server is published or started within Eclipse.
When requesting a URL like "http://localhost:8080/r5sis/", a directory
listing is the typical response if a "welcome" file doesn't exist.
However, in Tomcat 5.5.x, directory listings are disabled by default, so
a 404 is the normal response when no "welcome" file exists. My guess is
that you don't have a "welcome" file in your WebContent folder and
adding an index.jsp to this folder would fix would avoid the 404 error.
The default server instance that WTP creates includes an "empty" default
context. This is why "http://localhost:8080/index.jsp" also displays
404. In the server editor mentioned above, you can use the Modules tab
to add external contexts to this separate instance if you would like
make them available.

Thanks for your detailed response.
I think it doesn't matter to me whether it runs its own instance or uses
Tomcat installation. Thanks for the clarification. I would go with its own
instance other than disturbing the Tomcat installation. So I think my
application should still work fine without making this change.
Regarding the welcome files I have mentioned in my web.xml that:
<welcome-file-list>
<welcome-file>/jsp/login.jsp</welcome-file>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
Actually "login.jsp" is my welcome file and it is present in the
"WebContent/WEB-INF/jsp" folder and "web.xml" is in the
"WebContent/WEB-INF" folder. But still I get the same error. I even tried
placing a "index.htm" in the "WebContent" folder, but still in vain.
Please let me know what am I missing?
Thanks
Vignesh.

I haven't worked that much with Struts, but I don't believe the
"welcome" file handling and Struts inherently work together. You can
use one or the other, but I think the "welcome" file handling will
normally bypass the Struts handling. As a result, I don't think the
"welcome" file handling will be able to reach into the "WEB-INF"
directory. The trick of hiding JSP under WEB-INF only works for
includes and forwards, which Struts does, but for "welcome" file
handling that's getting bypassed.
Also, the way "welcome" files work is that when a "directory" resource
is requested, as in the URL in this case, the server checks for the
existence of a resource matching one of those in the welcome-file list.
The first one found is served. Specifying a "welcome" file like
"jsp/loging.jsp" kind of violates the intent of this feature by
"redirecting" to a resource in a different folder. It might work for
some servers, or it might not, or may work with side effects. It's not
a "feature" I would recommend using.
Thus, to get "http://localhost:8080/r5sis/" to work correctly, I think
you will need to declare "login.jsp" as the "welcome" file and actually
create such a file in the WebContent folder of your project. To get it
to perform the "real" login, put a "<jsp:forward />" in this file that
forwards to the appropriate Struts URL that will trigger the desired
login handling. I believe this will achieve the desired effect.

I understand what you said. I removed all the welcome files and just
included,
<welcome-file-list>
<welcome-file>index.htm</welcome-file>
</welcome-file-list>
and created "index.htm" in the "WebContent" folder, which just displays
"Hello world!". Still it doesn't work!
Now I wonder if I have done some real silly mistake. Any help?
Thanks

application should still work fine without making this change.
Regarding the welcome files I have mentioned in my web.xml that:
<welcome-file-list>
<welcome-file>/jsp/login.jsp</welcome-file>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
Actually "login.jsp" is my welcome file and it is present in the
"WebContent/WEB-INF/jsp" folder and "web.xml" is in the
"WebContent/WEB-INF" folder. But still I get the same error. I even tried
placing a "index.htm" in the "WebContent" folder, but still in vain.
Please let me know what am I missing?
Thanks
Vignesh.

When you create a Tomcat server within WTP, it will default to creating a
separate server instance, rather than "take ownership" of your Tomcat
installation. To see where the separate instance is found, double click
the Tomcat server in the Servers view and in the server editor that opens,
click the "Open launch configuration" link. In the launch properties
dialog, select the Arguments tab and note the setting for the
catalina.base system property in the VM Arguments field. You can have the
server in Eclipse use your Tomcat installation as the server instance by
unchecking the "Run modules directly..." check box in the server editor
and saving. Be aware that changing the server instance to the Tomcat
installation means the configuration files found under the Servers project
in your workspace become the "master" files for this Tomcat installation.
They will overwrite those in your installation each time the Tomcat server
is published or started within Eclipse.
When requesting a URL like "http://localhost:8080/r5sis/", a directory
listing is the typical response if a "welcome" file doesn't exist.
However, in Tomcat 5.5.x, directory listings are disabled by default, so a
404 is the normal response when no "welcome" file exists. My guess is
that you don't have a "welcome" file in your WebContent folder and adding
an index.jsp to this folder would fix would avoid the 404 error.
The default server instance that WTP creates includes an "empty" default
context. This is why "http://localhost:8080/index.jsp" also displays 404.
In the server editor mentioned above, you can use the Modules tab to add
external contexts to this separate instance if you would like make them
available.
Cheers,

I configured Eclipse WTP for a struts-enabled web application. When I ran
my application using "run on server" option, it gives a 404 error.
Below is my configuration:
Java - 1.4.2_13
Tomcat 5.5.23 with Java 1.4 compatible jars
Struts 2.0.6 with Java 1.4 compatible jars
Eclipse WTP 3.2.2
I created a new "dynamic web project" with Tomcat 5.5 as runtime, "r5sis"
as "context root" and "WebContent" as "Content Directory". I copied the
struts jars to the "WebContent/WEB-INF/lib" folder. The jsp files are
placed in "WebContent/WEB-INF/jsp" folder.
Find below my struts.xml and web.xml
<?xml version="1.0" encoding="UTF-8"?>
<struts>
<!-- Include Struts 2 default (from Struts 2 JAR). -->
<include file="struts-default.xml"/>

</web-app>
When I run the application by using "run on server" option, the tomcat
server starts without a problem and opens the url
"http://localhost:8080/r5sis/" in the browser.
It gives a 404 error, saying "The requested resource (/r5sis/) is not
available." "r5sis" is my project name. Also the project is placed only in
the eclipse workspace and not in the "<tomcat dir>/webapps" folder. Even
"localhost:8080/index.jsp" gives a 404 error.
When I tried running Tomcat from the command prompt, it runs properly and
"localhost:8080/index.jsp" works fine.
So the Tomcat is not working fine inside Eclipse WTP. Please let me know
what went wrong.
Thanks
Vignesh

My Struts knowledge, besides being rusty, never was that extensive in
the first play. Thus, on sight, I can't say if there is anything amiss
in your configuration. You could try creating another Dynamic Web
Project with just a welcome file and then start adding your Struts
configuration and see a what point the welcome file stops working. Then
research why that change is having the unexpected impact.
