Resin provides a fast servlet runner for O'Reilly WebSite Pro, allowing it to run servlets and JSP files.

To configure Resin with O'Reilly WebSite Pro, you must follow the following steps:

1. Configure WebSite Pro via its property sheet
2. Configure resin.conf with a text editor
3. Start srun. You may want to run srun as an NT service.

You should use resin1.x/bin/setup.exe to setup your configuration. If you use setup.exe, you can just skip to the next section.

WebSite Pro

1. Make sure Resin works via it's httpd.exe!
2. Stop WebSite Pro.
3. Copy isapi_srun.dll to the WebSite root directory, C:\WebSite.
4. Using the WebSite property sheet, Mapping tab, Associations list, associate .jsp, .xml and .xtp with the above extension C:\WebSite\isapi_srun.dl.
5. Using the WebSite property sheet, Mapping tab, Content types list, set the content type for .jsp, .xml, and .xtp to wwwserver/isapi.
6. Add isapi_srun.dll to WebSite's API pre-load list. Use the registry editor and add the full pathname of isapi_srun.dll, typically C:\WebSite\isapi_srun.dll, to the LoadLibrary string. This is located under HKEY_LOCAL_MACHINE\Software\Denny\WebServer\CurrentVersion. The variable name is LoadLibrary, and it is a semicolon-delimited string. Simply add ;C:\WebSite\isapi_srun.dll to the end of the LoadLibrary string.

Resin Virtual Server

In order to browse the supplied documents and samples, we strongly recommend creating a virtual server and mapping its root to the Resin doc directory. When creating this virtual server with WebSite's New Identity Wizard, you can uncheck both CGI options in the New Identity Wizard. Then after it's finished, change the / mapping from htdocs to doc. To set the virtual server up:

1. On WebSite's property sheet, Identity Tab, click New... and step through the New Identity Wizard. For this example, we'll assume that you used res as the URL prefix.
2. Create the following document mappings using the property sheet, Mapping tab, Document list. We'll assume the identity hostname is resin.foo.com and the URL prefix is res.
   1. Map /res/ to the Resin doc subdirectory
   2. Map /res/caucho-status/ to C:\WebSite\isapi_srun.dll\caucho-status\
   3. Map /res/servlet/ to C:\WebSite\isapi_srun.dll\servlet\
   4. Map /res/snoop/ to C:\WebSite\isapi_srun.dll\snoop\

1. Browse http://resin.foo.com/servlet/Hello and /foo.jsp. You should see a "cannot connect" error.
2. Start srun.exe
3. Browse http://resin.foo.com//servlet/Hello and /foo.jsp. You should now see the servlet.

Adjusting resin.conf

resin.conf should mirror the configuration of WebSite Pro. In other words, you need to configure the document root and any directory aliases.

For many users, you only need to change the app-dir attribute from 'doc' to something like 'c:\website\htdocs'. For more complicated configurations, you'll need to add path-mapping attributes.

Testing the servlet engine

From the Resin bin folder, you need to start srun.exe to start the servlet runner.

Now browse http://localhost/test.jsp. You should get a 'file not found' message.

Create a test file 'C:\WebSite\htdocs\test.jsp'

Browse http://localhost/test.jsp again. You should now get

As a final test, change language to 'java' and refresh the page. Nothing should change.

Troubleshooting

1. First, check your configuration with the standalone httpd.sh. Both httpd.sh and srun.sh use the same configuration file, so the results should be identical.
2. Check http://localhost/caucho-status. That will tell if the ISAPI extension is properly installed.
3. Each srun host should be green and the mappings should match your resin.conf.
4. If caucho-status fails entirely, the problem is in the isapi_srun installation.
5. Check that isapi_srun.dll is in C:\WebSite.
6. If caucho-status shows the wrong mappings, there's something wrong with the resin.conf.
7. If caucho-status shows a red servlet runner, then srun.exe hasn't properly started.
8. If you get a "cannot connect to servlet engine", caucho-status will show red, and srun.exe hasn't started properly.
9. If srun.exe doesn't start properly, you should look at the logs in resin1.x/log. You should start srun.exe -verbose to get more information.
10. If you get Resin's file not found, the WebSite configuration is good but the resin.conf probably points to the wrong directories.

The following configuration line arguments are recognized by srun.exe and httpd.exe. When installed as a service, these argument will be used when the service starts.

Deploying on NT

To install the service, use

To remove the service, use

You will either need to reboot the machine or start the service from the Control Panel/Services panel to start the server. On a machine reboot, NT will automatically start the servlet runner.
