Tomcat started in Eclipse but unable to connect to http://localhost:8085/
eclipse, http-status-code-404, tomcat
Solution
What are you expecting? The default Tomcat homepage? If so, you'll need to configure Eclipse to take control over from Tomcat.
Doubleclick the Tomcat server entry in the Servers tab, you'll get the server configuration. At the left column, under Server Locations, select Use Tomcat installation. This way Eclipse will take full control over Tomcat, this way you'll also be able to access the default Tomcat homepage with the Tomcat Manager when running from inside Eclipse. I only don't see how that's useful while developing using Eclipse.
Note, when it is grayed out, read the section leading text! It literally says "Server must be published with no modules present to make changes". In other words, make sure that you've removed all modules via rightclick server and Add and remove... option, and then performed rightclick server and Publish.
The port number is not the problem. You would otherwise have gotten an exception in Tomcat's startup log, and the browser would show a browser-specific "Connection timed out" error page and thus not a Tomcat-specific error page which could impossibly be served when Tomcat was not up and running.
Problem
I configured Tomcat 6.0.24 in Eclipse on port 8085 and started successfully with log as below: ``` Feb 17, 2010 4:24:31 PM org.apache.catalina.core.AprLifecycleListener init INFO: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: C:\Program Files\Java\jre6\bin;.;C:\WINDOWS\Sun\Java\bin;C:\WINDOWS\system32;C:\WINDOWS;C:/Program Files/Java/jre6/bin/client;C:/Program Files/Java/jre6/bin;E:\oracle\product\10.2.0\client_1\bin;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\system32\WBEM;C:\Program Files\Microsoft SQL Server\80\Tools\BINN;C:\Program Files\Common Files\Teleca Shared;C:\Program Files\Microsoft SQL Server\90\Tools\binn\;E:\Program Files\Microsoft Visual Studio 8\Common7\IDE\PrivateAssemblies\;C:\Program Files\MySQL\MySQL Server 5.0\bin;E:\komal-gohil\tools\Subversion\bin;C:\Sun\SDK\bin;e:\instantrails\ruby\bin;c:\program files\java\jdk1.6.0_11\bin;E:\komal-gohil\tools\apache-maven-2.2.1\bin;C:\program files\java\jdk1.6.0_11\bin;E:\komal-gohil\tools\Ant\bin;E:\komal-gohil\tools\apache-tomcat-5.5.17\bin;C:\Sun\SDK\lib\j2ee.jar;E:\komal-gohil\tools\android-sdk-windows-1.6_r1\tools;E:\komal-gohil\tools\Scala\bin;E:\komal-gohil\tools\pax-construct-1.4\bin Feb 17, 2010 4:24:31 PM org.apache.coyote.http11.Http11Protocol init INFO: Initializing Coyote HTTP/1.1 on http-8085 Feb 17, 2010 4:24:31 PM org.apache.catalina.startup.Catalina load INFO: Initialization processed in 705 ms Feb 17, 2010 4:24:32 PM org.apache.catalina.core.StandardService start INFO: Starting service Catalina Feb 17, 2010 4:24:32 PM org.apache.catalina.core.StandardEngine start INFO: Starting Servlet Engine: Apache Tomcat/6.0.24 Feb 17, 2010 4:24:32 PM org.apache.coyote.http11.Http11Protocol start INFO: Starting Coyote HTTP/1.1 on http-8085 Feb 17, 2010 4:24:32 PM org.apache.jk.common.ChannelSocket init INFO: JK: ajp13 listening on /0.0.0.0:8010 Feb 17, 2010 4:24:32 PM org.apache.jk.server.JkMain start INFO: Jk running ID=0 time=0/31 config=null Feb 17, 2010 4:24:32 PM org.apache.catalina.startup.Catalina start INFO: Server startup in 421 ms ``` But when I am trying to open `http://localhost:8085` in webbrowser, it is giving me the following error: HTTP Status 404 - / type Status report message / description The requested resource (/) is not available. Apache Tomcat/6.0.24 When I start Tomcat outside the Eclipse, then I can just open `http://localhost:8085` in webbrowser. What could be the reason for this? How do I solve this problem?
