 Posted: Wed 08 Jun '11 12:36 Post subject: Error 404 -- Not Found (Oracle web logic) |
 |
|
I am trying to configure Apache to use a local web page Missing.html if the back end application server is unavailable for any reason. I have stopped my application and deployed the Missing.html file to the D:\Program Files\Apache Software Foundation\Apache2.2 folder but I still get the message below.
Error 404--Not Found
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.5 404 Not Found
The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.
Here is the entry in the httpd.conf file.
#
# Customizable error responses come in three flavors:
# 1) plain text 2) local redirects 3) external redirects
#
# Some examples:
#ErrorDocument 500 "The server made a boo boo."
ErrorDocument 404 /error/Missing.html
#ErrorDocument 404 "/cgi-bin/missing_handler.pl"
#ErrorDocument 402 http://fcdbtest.banif.co.uk/subscription_info.html
#
What have I done wrong, any help much appreciated.
Many thanks |

Your url shows a an "error" directory.
So the Missing file must be in htdocs. if htdocs is your documentroot
| Code: | | D:\Program Files\Apache Software Foundation\Apache2.2\htdocs\error\Missing.html |
Even displaying the content from Missing.html the server still will send a 404.
How did you configure apache to the applicatin server? Reverse proxy? |

I have moved the Missing.html to the folder you mentioned but still the same error. WE are suing oracle web logic so we suer the weblogic LoadModule .
How d I know where the document root is pointing to, I am a novice at this. |

I guess your config is like
| Code: |
LoadModule weblogic_module modules/mod_wl_22.so
|
Having your code fragment from httpd.conf would help to understand that issue.
However in the RTFM for Parameters for Web Server Plug-Ins There is a parameter ErrorPage. I think that is what you might search.
e.g.
| Code: |
<IfModule mod_weblogic.c>
ErrorPage /error/Missing.html
</IfModule>
|
If you still have any question please ask again |

| Thanks very much, still not working but I think it is looking on the weblogic server not local so have logged issue with Oracle. |

| Just for my curiosity. Does the weblog server run like a "normal" tomcat on port 8080 and serves jsp files? |

| It is a middleware application server and sits between apache and the database. It serves web ages as well as housing the application business logic. We run on ports 7001 for mgt server and 7010 and 7020 for the application clusters. |

This is the reply from Oracle.
To configure the Apache server to look locally for the local html error page (Missing.html) so that if Weblogic is unavailable the Apache server will show Missing.html file stating the service is unavailable, you need to:
1.Make sure that Missing.html is located in the Apache DocumentRoot directory.
2.Confirm that Missing.html is accessible using http://hostname:port/Missing.html
3.Configure the Apache plugin as following:
| Code: |
<IfModule mod_weblogic.c>
SetHandler weblogic-handler
WebLogicCluster 10.100.18.32:7010,10.100.18.32:7011
MatchExpression /B001/ENULogin.jsp,/B001//INALogin.jsp,/F001//INALogin.html
SecureProxy OFF
Debug ALL
WLLogFile "D:/Program Files/Apache Software Foundation/Apache2.2/logs/wlproxy.log"
ErrorPage http://hostname:port/Missing.html
</IfModule>
|
> Please note that you should use:
ErrorPage http://hostname:port/Missing.html
instead of:
ErrorPage /Missing.html
However I am unable to access the Missing.html document either locally on the apache server or remotely so I guess I need to change something but what? Below is the httpd.conf file do I need to change anything here?
| Code: |
ServerRoot "D:/Program Files/Apache Software Foundation/Apache2.2"

I think you alread putted the Missing.html into htdocs\error\ don't you?
So the config would be
| Code: |
ErrorPage http://10.28.205.96:80 /error/Missing.html
|
Before try that link in your browser
Hope that helps. By the way: I see that you don't use mod_deflate. if you would do it will reduce the traffic in the network and speed a bit up. |

| What is the error message in your browser? What is the error about this in your apache error log and access log? |

| I still cannot get this to work. I am unable just to get the Missing.html document to come up so I guess the apache is not serving documents only from the weblogic server. |

I can only access the Missing.html file if I comment out the
<IfModule mod_weblogic.c>
Include conf/extra/weblogic.conf
</IfModule>
Sections, so I guess I need to put something in the welogic.conf file, back to Oracle. |

I've tried a bit, I was able to make a reverse proxy to a weblogic server without mod_weblogic, but mod_proxy_ajp. I don't know if there is some magic from mod_proxy_html needed for you. BUT if you are able to run the reverse proxy with apaches own modules you can define that error pages with the normal apache behaviour.
I'm not into the mod_weblogic so I don't know if there is something special you need that mod_proxy_* can't provide. |

The fix was a change to the way weblogic module was configured just in case anyone has similar issue I have posted the weblogic.conf file below.
<IfModule mod_weblogic.c>
<LocationMatch /(B|F)001>
SetHandler weblogic-handler
WebLogicCluster 10.100.18.32:7010,10.100.18.32:7011
SecureProxy OFF
Debug ALL
WLLogFile "D:/Program Files/Apache Software Foundation/Apache2.2/logs/wlproxy.log"
ErrorPage http://10.28.205.96/Missing.html
</LocationMatch> |

Hi michael,
I have modified my httd.conf file as you mentioned. But still am unable to get the error page. Have pasted my virtual host conf below. my error page is located in htdocs folder and am able to access through browser.
<Location ~ /BMP>
SetHandler weblogic-handler
WebLogicCluster 10.28.1.10:61001,10.28.1.11:61002,10.28.1.12:61003
Debug ON
WLLogFile /software/bea/apache/2.2.14/logs/wl_proxy_managed.log
WLTempDir /software/bea/apache/2.2.14/logs
ErrorPage http://10.36.1.9/BMPError.html
SetOutputFilter DEFLATE
AddOutputFilterByType DEFLATE text/html text/plain text/xml text/javascript
</Location>
below is the access logs:
[01/Mar/2012:05:58:20 +0000] "GET /BMP_Home HTTP/1.1" 404 697
Does the ErrorPage option will redirect for 404 or only 503? Please reply me ASAP.. |
