Use this information to troubleshoot problems that occur when attempting to display a resource in a browser.
If you cannot access the resource directly through the Application Server, verify that the URL used to access the resource is correct.
If the URL is incorrect and it is created as a link from another JavaServer Pages (JSP) file, servlet, or HTML file, try correcting it in the browser URL field and reloading, to confirm that the problem is a malformed URL. Correct the URL in the "from" HTML file, servlet or JSP file.
View the JVM log of your Application Server to find out why your resource cannot be found or served .
http://hostname/myapp/servlet/com.mycom.welcomeServlet
If none of these steps fixes your problem, see if the problem has been identified and documented by looking at available online support (hints and tips, technotes, and fixes). If you do not find your problem listed there, see Troubleshooting help from IBM.
If you are unable to view the welcome page of your HTTP server, determine if the server is operating properly.
If restoring the HTTP server default configuration file works, manually review the configuration file that has WebSphere Application Server updates to verify directory and file names for WebSphere Application Server files. If you cannot manually correct the configuration, you can uninstall and reinstall WebSphere Application Server to create a clean HTTP configuration file.
If restoring the default configuration file does not help, contact technical support for the web server you are using. If you are using IBM HTTP Server with WebSphere Application Server, check available online support (hints and tips, technotes, and fixes). If you do not find your problem listed there, see Troubleshooting help from IBM.
You can bypass the HTTP server and access a web resource through the application server. It is not recommended to serve a production website in this way, but it provides a good diagnostic tool when it is not clear whether a problem resides in the HTTP server, WebSphere Application Server, or the HTTP plug-in.
