Hi Jerry,
Do you actually need to use the machine name? I have had good luck
running everything under localhost. If you want to take a bash at this:
1. Add -WOHost localhost to your app launch parameters
2. Add -WOHost localhost to /System/Library/WebObjects/
JavaApplications/wotaskd.woa/Contents/Resources/Properties
3. Edit your apache.conf file to use WebObjectsConfig http://
localhost:1085 10
4. Configure JavaMonitor to use localhost as the host name
5. Stop and start Apache, wotaskd, your app
I don't see any references to WOHost setting below, just -
WHServerName jwpismo which may do the same thing for a WireHose
project, I don't recall.
So, by changing the above instructions to use jwpismo instead of
localhost may also work. May. The key issue seems to be to get
Apache, wotaskd, and the app all using the same host name.
This pretty much always works for me with the occasional need to
apachectl restart

Greetings,
Back at the end of June, my well working network settings got hosed
and though I got help from the list, the requirements I was facing
at the time didn't justify playing the network game to get my
laptop (which typically operated in three different network
environments daily) to test through the web server, so I punted and
started using WODirectConnect. What a nice crutch.
Thought I've since had a reduction in the number of network
environments in which I'm actively developing with my laptop,
direct connect has worked fine until this week when I've had
problems directly associated with WODirectConnect. So with a little
time available this weekend, I was hoping to re-establish testing
through the web server on my machine.
Unfortunately, I can't seem to get wotaskd to see my app. When the
app fires up, the browser displays the message:
The requested application was not found on this server.
Sure enough, when I check wotaskd at http://jwpismo:1085/, the
browser displays the appropriate page with the following section:
============================================
Adaptor Config as sent to Local WOAdaptors - All Running
Applications and Instances
<?xml version="1.0" encoding="ASCII"?>
<adaptor>
</adaptor>
============================================
Hmmm. Definitely not recognizing the app.
To get this far, I've followed an incantation first recited to me
by Master Wizard Gary Teter late last year when I asked how he
would set up a Mac OS X WO development laptop named "jwpizmo"
facing the network changes mine faced every day.
He mystically committed the following words to paper for me:
============================================
1. Set up a virtual doman called "jwpismo" in Apache by modifying /
etc/httpd/httpd.conf:
1A. Under the line: "#NameVirtualHost *:80" add this line:
NameVirtualHost *
1B. Add the following VirtualHost block:
<VirtualHost jwpismo *>
ServerName jwpismo
DocumentRoot /Library/WebServer/Documents/
ErrorLog /private/var/log/jwpismo.com-error_log
CustomLog /private/var/log/jwpismo.com-access_log common
</VirtualHost>
2. Set up an entry in netinfo:
1. Open /Applications/Utilities/NetInfo Manager
2. Choose "Authenticate..." from Security menu
3. Enter password
4. Select "machines" in 2nd column
5. Select localhost
6. Click Duplicate
7. Change name to "jwpismo"
8. Remove "serves: ./local" entry
9. Save changes
============================================
He suggested a third step to manually configure the woapps, which I
DID NOT DO:
============================================
3. Manually configure WebObjects applications. In httpd.conf,
comment out this line if it exists:
Include /System/Library/WebObjects/Adaptors/Apache/apache.conf
Add this entry at the end of /etc/httpd/httpd.conf:
Include /private/etc/httpd/webobjects.conf
Copy apache.conf:
sudo cp /System/Library/WebObjects/Adaptors/Apache/
apache.conf /etc/httpd/webobjects.conf
Edit webobjects.conf:
Change this line:
WebObjectsConfig http://localhost:1085 10
to this:
# WebObjectsConfig http://localhost:1085 10
Add this line:
WebObjectsConfig file://etc/httpd/WOConfig.xml 10
Create /etc/httpd/WOConfig.xml:
<?xml version="1.0" encoding="ASCII"?>
<adaptor>
<application name="Store" urlVersion="4">
<application name="FoundImage" urlVersion="4">
<instance id="1" port="2001" host="localhost"
recvTimeout="300"/>
</application>
</adaptor>
============================================
I then set launch arguments appropriately in Xcode:
-WOAdaptorURL http://jwpismo/cgi-bin/WebObjects
-WODirectConnectEnabled NO
-WOPort 2001
-WHServerName jwpismo
So following all that, wotaskd fails to recognize my running app.
I did the following checks from Chuck Hill's invaluable network
diagnostics guide (published a couple times on this list):
1) Get wotaskd running at boot if it is not
2) Enable Personal Web Sharing
3) Launch app with -WODirectConnectEnabled false
4) (optional ease of use thing) add -WOPort 3456 or whatever you
will remember so the URL will be consistent
5) Build and run
1A. Make sure that wotaskd really is running:
It is:
1052-27-17:37:08-jwpismo% sudo lsof -i tcp:
1085 ~
Password:
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
java 188 root 7u IPv6 0x018e0f48 0t0 TCP [::
127.0.0.1]:webobjects (LISTEN)
1B. Check the config file. This is not strictly needed for dev
launches, but let's nip any troubles in the bud.
1053-27-17:39:56-jwpismo% ls -l /Library/WebObjects/
Configuration/ ~
total 8
-rw-r--r-- 1 root admin 351 Oct 27 16:09 SiteConfig.xml
Do you see any permissions conflict on your machine? <NOPE> If so,
fix them. <No need here> The wotaskd process need to write to this
file.
2. Enable Personal Web Sharing
It's enabled, I have no trouble obtaining a document with
"http://jwpismo/~jwalker/"; at my local machine.
3. Launch app with -WODirectConnectEnabled false
It is so set.
4. (optional ease of use thing) add -WOPort 3456 or whatever you
will remember so the URL will be consistent
Set to -WOPort 7777
5. Build and run
I did. No go.
Following that failure, I looked everything over carefully again
and modified the apache.conf file to add the jwpismo host in the
Host List Configuration with the following line:
WebObjectsConfig http://localhost:1085,http://jwpismo:1085 10
Still no go. So does anyone have any idea why the app is failing to
let wotaskd know that it's running?
Regards,
Jerry
