For the 1000th time... Ethernet Issues...
I read as many posts regarding this as possible... I just wanted to get all my info together so I can march home and confront the beast....
My new to me G4's ethernet port is dead. Trying to hook up to DSL via ethernet... Tested it with known good cables, DSL modem, tech support from my ISP (for settings), etc...sooo... I bought a wireless Linksys router and spent 3 hrs on the phone with them... finally got on with the G4 for about 10 minutes then lost all connectivity. Anyhooo... I am sending the router back as advised by Linksys... and trying the ethernet again...
I thought I would try a few things to revive my ethernet port so after reading yall's wise words I have the following list of to dos...not necessarily in order...
1. Make sure cords/modems/etc are all working (DONE)
2. Reset the PRAM
3. Make sure the cord is plugged in prior to booting the computer
4. Run the Disk tool utility that came with the computer
5. Scream, cuss, jump up and down
6. If all this fails buy a PCI ethernet card...
Anything I am leaving out?
Thanks so much!!
Hello! "finally got on with the G4 for about 10 minutes" would indicate that the port is not dead but could be a connectivity issue. I would get a powered magnifying glass and examine the ethernet port for problems. There can be two common types of problems. One is where an examination of the port reveals that the tiny four wires which are like little flat springs become distorted and they are not all at the same height. (all four should be at the same position) The second situation involves the wires not being bright and shiny in color. They may be bluish in color (usually from voltage spikes) and may be cleaned with a tiny wire brush or possible the edge of a small knife. Tom

HT1349 I can no update my itunes for some reason for the first time having issues nothing happens
I've never had an issue before with updating itunes, but this time, there is an update available and it will not update it. Nothing happens. Everything else in iTunes appears normal as far as apps are there, songs, tones etc... that I've recently purchased. I want to update iTunes then sync my phone. Well, I went ahead and tried to sync my phone without updating iTunes and when I connected my phone I get this message.
"iTunes could not connect to this iPhone because an unlnown error occured (OxE80000001)"
I'm clueless as to what is going on. I've rebooted my computer and that is all.see your error code here http://support.apple.com/kb/TS3221 follow instructions to resolve.

For the second time (I've been to the Genius Bar already once with this) my Wifi isn't working. They gave me a new iphone last time, but the new one has the same issue as the old one, I'm guessing. I've tried resetting the network but that doesn't work.
I see others have this issue too.
If this is a hardware problem why doesn't Apple fix it? Or do I just have to wait another year for another upgrade?
Currently it's not costing me anything - yet - because I've got the Apple Warranty but this is totally frustating!!! I bought the original phone (which has been replaced in July 2012. The new phone (without working Wifi) is a month old.
Will try Restore via ITunes before (I will invariably) have to return to the Genius Bar for another Iphone 4S unless someone has an ingenius solution here?..?sematson wrote:

For what reason, other than making yourself look foolish, would you ask questions that we users could not possibly answer as we're NOT Apple?
Basics from the manual are restart, reset, restore from backup, restore as NEW. Nothing more "ingenius" to suggest than these steps that Apple has outlined in the manual. If these steps don't work, then go back to the Apple store. -
I recently shut down my MacBook Pro for the first time in a long time. SInce then, everytime i reboot or awake my laptop from sleep, the Mail app opens unprompted causing my computer to slow down incredibly, and some apps to freeze. I have no idea how to stop this or why it even started doing this. Any ideas on how to get it to stop? Thanks!
I have this problem too with my Macbook Air. Mail opens automatically every time my laptop sleeps. I actually just asked about this in my own thread. However, it is not causing my apps to freeze.

How to set up Airport Extreme with Charter ARRIS Modem TM902A for the first time for WIRELESS.
How to set up Airport Extreme with Charter ARRIS Modem TM902A for the first time for WIRELESS.
When Charter Tech goes to your site, have them connect the modem up, but do not connect the modem to your iMAC or MacBook Pro. What you want to do is connect the Airport Extreme to the iMac or MacBook Pro first with the Ethernet Cable. You have to do this to configure via Airport Utility to set up the Base Station Name & Base Station Password.
You will then create/configure a Wireless Network, create your Wireless Password that will be entered on each of your Devices, example, Apple Tv, your iPhone, etc., you want to allow access to your Wireless Network you are creating.
Wireless Security will be -> WPA/WPA2 personal or just WPA2
Enter the Wireless Password you want
Verify the Wireless Password (enter it again)
After it is created you will see it on the Airport Utility window with the name you created for it and to the left, will be a Dot (circle that will be yellow).
Next you then want to unplug the power to the Airport Extreme, and then take the end of the Ethernet cable you unplugged from the iMac or Lap top MacBook Pro and connect it to the back of the Modem.
Next unplug the power cord from the modem and wait about 5 minutes, then plug the power back into the Arris Modem and wait until all lights come back on the modem wait
about 5 minutes, then plug the power cord back to the Airport Extreme and you will see it the light blinking yellow. Wait about 5 to 10 minutes, during this time Restart you IMAC or MacBook Pro, and once it is back up click on the Airport Utility and you should see on the Airport Utility screen.
For INTERNET to the left the light should be green and you should see the Airport Extreme also appear and the light to the left on the screen should also be green. If they are, you then should be able to click on the Wireless Symbol on top of bar of the screen and click to select the Wireless Network Name you created.
If you Do Not See the light (Icon) next to INTERNET turn Green, or if you see the Internet Light Green, but the Light (Icon) next to the Airport Extreme is yellow, unplug the power again to the modem and unplug the power again to the Airport extreme and wait about 15 minutes or up to 30 minutes. Then plug the power cord back to the modem wait till all the lights light up then, plug the power cord back into the Airport Extreme and Restart your iMAC or MacBook Pro.
The Airport Extreme light should change from yellow to green. Open up the Airport Utility to see what the indicators are showing they should both be green. Again select Wireless network you created under the Wireless Icon on the top right of the screen. Open Safari and see if you are able to Route to a web page or the apple site should appear.
WHAT TO DO IF YOUR AIRPORT EXTREME WAS PREVIOUSLY SET UP FOR USE WITH ANOTHER CARRIERS ROUTER OR MODEM.
NOTE: If you already had your Airport Extreme connected for example, I previously had ATT Uverse and the Airport Extreme was connected to the Wireless Router Model 3801HGV, I disabled the Uverse Wireless and used the Airport Extreme for the Wireless signal in bridge mode, as the Airport extreme Signal is much stronger than the Uverse router, and I was able to obtain a Wireless signal with the Airport Extreme way much better with no signal loss which was very very frustrating with the Uverse router.
Anyhow if you had it hooked up like this, now that you will be using it with the Charter ARRIS Modem TM902A, you will need to reset the Airport Extreme to clear out the old data it has in memory, with the previous set up otherwise it will not work. Trust me I spent 6 hours trying to make it work reading all Apple Support Community questions and answers relating to this type issue/problem others have been having trying to get their set up working. I tried all the tips, and I finally decided just to see if by chance I would be able to connect with someone with Charter Tech support who might be familiar with Apple to be able to assist me and by luck I did. He told me why it was not working and was all due the previous configuration with the ATT Uverse router was still in memory with the Airport Extreme. Finally it was 10:30 PM when I decided to call Charter Tech Support and I had been working on this since 3:00 pm pacific. I did not call them earlier as all the post I read said they never received any good help from Charter. After calling them I finished up by 11:00 PM and was able to finally connect Apple Tv, iMac, iPhones and Macbook Pro. We love our Apple Product and Happy all is connected with the new
Internet Provider Charter. I must say the speed is way way much better than it ever was with AT&T Uverse.
THIS IS WHAT YOU WILL NEED TO DO:
First you will need to unplug the Airport Extreme, then by taking the tip of a pen or paper clip end you need to push the reset button on the back of the Airport Extreme and hold it
down and at the same time plug the power cord back into the Airport Extreme count to 5 or 10 then release the reset button. Then once he light in front of the Airport Extreme stops blinking you need to plug the Ethernet cable from the Airport Extreme to your iMAC or Macbook Pro, and restart which ever one you have, then open the Airport Utility once it is back up. If you see airport extreme pop up with the old network name or it shows and yellow triangle click on the Airport Extreme ICON it will not let you configure it but will ask if you want to get rid of it or remove and just do it. Then Again restart your iMAC or MacBook Pro, open up Airport Utility again, and on the top left you should see under “Other Airport Base Stations” the MAC ID for the Airport Extreme.
You will then create/configure a Wireless Network, create your Wireless Password that will be entered on each of your Devices, example, Apple TV, your iPhone, etc., you want to allow access to your Wireless Network you are creating.
Wireless Security will be -> WPA/WPA2 personal or just WPA2
Enter the Wireless Password you want
Verify the Wireless Password (enter it again)
After it is created you will see it on the Airport Utility window with the name you created for it and to the left, will be a Dot (circle that will be yellow).
Next you then want to unplug the power to the Airport Extreme, and then take the end of the Ethernet cable you unplugged from the iMac or Lap top MacBook Pro and connect it to the back of the Modem.
Next unplug the power cord from the modem and wait about 5 minutes, then plug the power back into the Arris Modem and wait until all lights come back on the modem wait
about 5 minutes, then plug the power cord back to the Airport Extreme and you will see it the light blinking yellow. Wait about 5 to 10 minutes, during this time Restart you IMAC or MacBook Pro, and once it is back up click on the Airport Utility and you should see on the Airport Utility screen.

I have a Linksys WRT320N I used for the initial Charter setup.
I can get my Airport to work here, but the Internet light on the Modem flashes Yellow.
Hasn't caused any issues so far but one thing I did notice.
On the Linksys there were 3 DNS servers listed.
The Airport Extreme only lists 2 and i don't see where I could add another, only change whats already there.
I tried everything above, but light on modem still flashes yellow.
I have the technicians cell phone. Told me "that shouldn't be" and gave the same advice listed above.
I'll break down and call Charter one day, see if it's on their end. NSA tracking may need a reset LMAO. -
Time Machine: Repeated errors when backing up for the first time using a new external firewire drive
My Iomega 500GB firewire external drive failed on me last week and I have just replaced it with an identical model. I used to use the old drive with Time Machine on my MacBook Pro running 10.5.8 with no issues, until the drive had a hardware failure and stopped spinning up, hence the replacement.
Two days ago I tried using Time Machine for the first time with the replacement external drive. The backup failed and each subsequent backup attempt has failed since then with a different error each time. The drive cannot be ejected using Finder (Finder says disk is in use and cannot be ejected even when no processes are running except for Finder and Time Machine has been disabled), by dragging it to the dock (hangs computer which can only be fixed by a hard reboot), in Disk Utilities (drive cannot be unmounted) or in Terminal ("no such file or directory").
The first backup attempt failed after 3 hours of "preparing" with the message "The backup was not performed because an error occured while creating backup directory".
I tried repairing the disk in Disk Utilities and Disk Utilities said the drive was OK ("the volume Time Machine Backups appears to be OK"). I tried ejecting the drive (hard reboot of computer and disconnecting the drive), plugging it back in again and trying again.
This time it started backing up, then failed after a few minutes with the message "an error occured while copying files to the backup volume". I had a look at the troubleshooting suggested on http://web.me.com/pondini/Time_Machine/C3.html and followed instructions. It failed again, so I did a full reset as per http://web.me.com/pondini/Time_Machine/A4.html.
It failed again, so I tried reparing the drive again in Disk Utilities and again it said it was OK. I tried using different cables and ports (Firewire 400 instead of Firewire 800), and backups still fail.
I have turned off anti-virus scanning (Sophos). I have tried excluding it from Spotlight but this causes an error message from Spotlight. I have tried trashing the com.apple.TimeMachine.plist file and rebooting. I have tried selecting deselecting the drive as the back up in Time Machine preferences, selecting "None", then "Stop Backing Up" then quitting preferences, rebooting, disconnecting the drive, reconnecting the drive and selecting the drive again as the backup disk in Time Machine preferences. I have tried erasing the drive completely, rebooting, and trying to back up again.
None of these have worked. This is a brand new drive and I do not want to have to replace it again if I do not have to.
Does anyone have any suggestions? Thank you.Hello, some possible clues...
Should you click “Start New Backup”? Not yet! If you see the dialog above, your existing Time Machine backup is corrupt, and you might not be able to recover data from it. But you can save a copy of the corrupt bundle and, perhaps, extract some data from it if needed.
Ask yourself if Time Machine has saved data you might need before deciding what to do next:
If you are sure you won’t need anything backed up before today, click “Start New Backup” and let Time Machine do its thing.
Otherwise, click “Back Up Later” and save a copy before letting Time Machine start a new backup. Just look for a file called “computername.sparsebundle” (for network backups) or “Backups.backupdb” (for local ones) and create a copy with a different name. You can open sparsebundle files with DiskImageMounter and browse them like any other disk. More information is available here.
There you go. If you click “Start New Backup” when you see this dialog box, Time Machine will erase all of your old backup data and start a new bundle. It won’t be corrupt, but it will be empty.
Note that you can manually initiate a Time Machine backup integrity check by option-clicking the “Time Machine” icon in the menu bar and selecting “Verify Backups.”
http://blog.fosketts.net/2010/08/11/time-machine-completed-verification-backups- improve-reliability-time-machine-create-backup/
According to This Time Machine resource “This appears only on Snow Leopard, and started with the Time Capsule Backup Update 1.0 in mid-May of 2010. It also seems to have been included in the 10.6.3 v1.1 update and 10.6.4.”
So, what can you do about it? Grin and bear it, it seems, until Apple fixes it.
One thing you can do to make the backup take less time is to connect your machine to your Time Capsule or other backup drive via Ethernet for the duration of the initial backup.

Problem while refreshing the data for the second time using excel services in sharepoint 2013...
Hi,
I have migrated my Sharepoint from 2010 to 2013.I am able to get the data at the first time of refresh when I click on refresh for the second time I am getting the empty the sheet.
below find the flow of refresh
First Refresh
On Click of refresh open the workbook with excel services and return the session id.
Using that session I am invoking RefrehAsync method of excel services
After refresh completed I am setting the calculation of workbook as automatic(to calculate the formulas) using the same session id
After setting the calculation as Automatic I am setting the calculation type as full(recalculate) using the same session id.
Now I am able to see the data
Second Refresh
After clicking on refresh instead of opening the workbook I am using the session id(already opened workbook) and setting the calculation type as manual
I am following the same process from refresh(RefreshAsync) as I have followed in first refresh.
This time my formulas are not getting calculated because of that I am not able to see the data.
Could you please let me know that am I missing anything here?
Is this know issue in Sharepoint2013 excel services as same code is working fine with Sharepoint2010.
If I close the workbook(session id null) and opens(new session id) for all the refreshes it is working and I am able to see the data.
Thanks,
Meenakshi Nagpal
N.MeenakshiI am able to see the data for the second refresh if I change the data source.If I use the same data source which is used in the first refresh I am not getting the data.Excel services will contact the cubes and calculate the formulas in my workbook.
Could you please let me know what could be the problem at second refresh while contacting the same data source with same session id?
Please help me asap.
Thanks,
Meenakshi Nagpal

Phone not working for the 5th time
I am so happy with my fios service. Now for the 5th time our phone does not work. We regularly cant recive calls, and sometimes cant call out. Each time we call (with cell) they say nothing is wrong and will send a tech out days later and an hour before the tech is supposed to show up, it suddenly starts working again. A week later it stops working, and we go through the same ordeal. I wonder who they cut off, whent hey turn ours on, and who gets service when they cut ours off. Its like they play musical chairs with our phone service. Sometimes we get incomming calls, sometimes outgoing, but hardly ever both. **bleep**? Now waiting another 8 days for them to send someout out because right now we dont even have a ring tone. Please just fix the problem, or stop charging us the $30 for the service. What a sham. Oh, and to top it all off,t his week, Verizon Wireless also assigned my wifes account/phone number to someone elses contract. She has had the number for over 10 years, I just bought her a new iPhone (full price $900) and when we went the store a man by the name of Carlos told us to pound sand. He had given the line to someone else and the only way he would fix it is if we returned the phone we bought from Verizon online, and bought a phone in his store!!! Can you believe it. Carlos would not give her line back unless she bought a phone in his store.

I’ve tried to update my i-Tunes version after the site suggested I should following my i-Pad Air being plugged into it for the first time. The update seemed successful but the program would not open at all despite switching off the PC and re-starting several times. I then tried wiping the original software from the computer and re-downloading from scratch. Each time I tried the download failed with a message saying “Service “Apple Mobile Device” failed to start. Verify that you have sufficient privileges to start system services” At this stage, the only way forward was to “abort” the download. This I have done now four times and the same thing happens. When I did finally manage to get an i-Tunes shortcut on my desktop, the program wouldn’t open saying: “i-Tunes was not installed correctly. Please re-install i-Tunes. Error 7 (Windows error 193)” Any ideas to resolve this?

Troubleshooting issues with iTunes for Windows updates -
I downloaded Iphoto 11 9.2 from the apps store (was on iphoto '09 before version 8.x) and when opened it for the first time it tried to update my photo librery and ended up corupting it to the extreme that I had to get a backup from time capsule and downgrade my iphoto version. I spent yesterday 6 hours at the genius bar in an apple store and they were not able to provide me with any other solution. In the emantime, I have to forget about about photo streaming... Any idea, is this a bug that somebody knows how tp fix?
In fairness, this isn't an issue in iPhoto 11 but one in your Library. Some file or other in there is damaged and that's what causes the crash during the upgrade.
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. -
2009 MBP can't see internal hard drive - for the second time!
Well, my 2009 13" MBP is at Applecare for the second time because it cannot recognize _any_ internal hard drive.
The first repair came at 9 months (purchased new), now 16 months later I have the same issue.
Swap in a known good drive, it can't see it, boot from DVD, and run Disk Utility, it can't see it either (optical drive shows up fine)
My first repair only said they replaced the original hard drive, has anyone else had the issue of losing access to your internal hard drive?
Ugh, I will be out of the 3 year Applecare next summer, and don't want to get stuck with another iBook G3, if you know what I mean.
Thanks for any feedback!Hi
I have the same issue, I have a Vodafone branded Huawei HG556a with an external drive connected. I have found that it isn't possible to connect via Finder and that SMB doesn't work either. The only way I could connect to it was via FTP using Cyberduck (or Filezilla), but no use as I can't add my media files from the drive to iTunes, so unfortunately disappointing. I'm still looking, but here's the document I was referred too from another forum.
broadband.vodafone.ie/download/files/storage_mac.pdf
Although not an answer to your question, hopefully this will give you an idea why you are getting the password and username errors when you know they are correct. In the end when I entered the FTP details into Cyberduck I was able to connect.
I know this doesn't help solve the problem (as I'm still looking too), but at leas you know why (ish).
Cheers

'BAPI_GOODSMVT_CREATE' takes more time for creating material document for the 1st time
Hi Experts,
I am doing goods movement using BAPI_GOODSMVT_CREATE in my custom code.
Then there is some functional configuration such that, material documents and TR and TO are getting created.
Now I need to get TO and TR numbers from LTAK table passing material documnt number and year, which I got from above used BAPI.
The problem I am facing is very strange.
Only for the 1st time, I am not finding TR and TO values in LTAK table. And subsequent runs I get entries in LTAK in there is a wait time of 5 seconds after bapi call.
I have found 'BAPI_GOODSMVT_CREATE' takes more time for creating material document with similar issue, but no solution or explanation.
Note 838036 says something similar, but it seems obsolete.
Kindly share your expertise and opinions.
Thanks,
AnilHi,
please check if some of following OSS notes are not valid for your problem:
[Note 838036 - AFS: Performance issues during GR with ref. to PO|https://service.sap.com/sap/support/notes/838036]
[Note 391142 - Performance: Goods receipt for inbound delivery|https://service.sap.com/sap/support/notes/391142]
[Note 1414418 - Goods receipt for customer returns: Various corrections|https://service.sap.com/sap/support/notes/1414418]
The other idea is not to commit each call, but executing commit of packages e.g. after 1000 BAPI calls.
But otherwise, I am afraid you can not do a lot about performance of standard BAPI. Maybe there is some customer enhancement which is taking too long inside the BAPI, but this has to be analysed by you. To analyse performance, just execute your program via tr. SE30.

Setting up a cluster for the first time: newbie questions
Any help appreciated with this situation:
I'm trying to set up a cluster for the first time and running into
issues (no big surprise). I'll outline my situation and pose questions
as they arise. If/when I get things to work I'll post a step-by-step
summary of what it took to get a simple cluster going.
Here's what I have:
machines:
1 Windows 2000 machines with WL 6.1
2 RedHat Linux machines with WL 6.1
All machines are on the same Home LAN, can see each other, etc.
IP addresses are:
Windows box: 192.168.1.100
Linux box 1: 192.168.1.102
Linux box 2: 192.168.1.103
servers:
I've set up the Windows machine as my admin server, and set up
a managed server on each Linux machine. I created a cluster that consists
of the 2 Linux machines and deployed the web app and EJB to the cluster.
The Windows machine is acting as a Proxy using ClusterServlet.
The web application has been set as the Default Web Application on the
two Linux machines. All 3 machines are listening on ports 80/443. I also
set up session memory replication through the console.
Application:
I have an application that I package as an EAR file. I'm using it as a
"reference" application designed to mimic a real world app as much as possible.
The EAR file contains a web application that uses Struts. It also consists
of a single Stateless Session Bean. The WAR file and EJB Jar are all
packaged up into the EAR file. I've been able to run this application just
fine on a single managed server on all 3 machines.
The web application works fine, and it can invoke the EJB. I can also
invoke the EJB from Java stand-alone clients. Struts works great. All is
well with the world. Now I'm trying to "cluster-ize" this app using
the environment described above and encountering issues.
I've read the docs and followed the instructions according to the
"Weblogic Bible" book. I can bring up all 3 servers and the Linux
managed servers connect to the cluster just fine. I can also
see the Struts messages in their logs which normally happens and tells me
the webapp is initialized properly. The console tells me that the managed
servers are running. I get no error messages starting up any of the serves.
Here are the problems I am encountering.
When I try to access the Web Application (through a browser on the
Windows machine using http://localhost) I get the following error message:
<Nov 19, 2002 6:44:33 AM EST> <Error> <HTTP> <HttpServer(1754841,null default ct
x,admin) found no context for "/". This request does not match the context path
for any installed web applications and there is no default web application confi
gured.>
Also, when I try to invoke the EJB through a stand-alone Java client,
I get a JNDI lookup error on the EJB's home interface.
Questions:
Question1: I noticed when setting up the machines that console lets you
define a "Machine" or a "Unix Machine". What's the difference? Should I
define the Linux machines as Unix machines or machines, and what are the
consequences of either choice?
Question2:
I'm not totally clear on how my web.xml should look to set up Struts,
the ClusterServlet, and a servlet filter I'm using to test Servlet filters.
Here is what I had before I tried to cluster and which works fine:
<filter>
<filter-name>MainFilter</filter-name>
<filter-class>com.refapp.servlets.MainFilter</filter-class>
<init-param>
<param-name>myAttribute</param-name>
<param-value>Foo</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>MainFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping
<!-- Struts ActionServlet Configuration -->
<servlet>
<servlet-name>action</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
<init-param>
<param-name>application</param-name>
<param-value>refappstruts</param-value>
</init-param>
<init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/struts-config.xml</param-value>
</init-param>
<init-param>
<param-name>debug</param-name>
<param-value>2</param-value>
</init-param>
<init-param>
<param-name>mapping</param-name>
<param-value>org.apache.struts.action.RequestActionMapping</param-value>
</init-param>
<load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.do</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>index.html</welcome-file>
</welcome-file-list>
(I have set up a "dummy" 0-length file called index.do that triggers
Struts to go into its ActionServlet when first accessing the web site).
Here is how I added ClusterServlet to web.xml:
servlet>
<servlet-name>ClusterServlet</servlet-name>
<servlet-class>weblogic.servlet.internal.HttpClusterServlet</servlet-class>
<load-on-startup>0</load-on-startup>
<init-param>
<param-name>defaultServers</param-name>
<param-value>192.168.1.102:80:443|192.168.1.103:80:443</param-value>
</init-param>
<init-param>
<param-name>DebugConfigInfo</param-name>
<param-value>ON</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>InitServlet</servlet-name>
<url-pattern>/servlet/InitServlet</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>ClusterServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>ClusterServlet</servlet-name>
<url-pattern>*.html</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>ClusterServlet</servlet-name>
<url-pattern>*.jsp</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>ClusterServlet</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
Clearly there is a problem with the Default Web application not being
seen/mapped properly. Any chances my URL mappings for the filter servlet,
Struts, and ClusterServlet are stepping on each other?
With respect to the EJB, here is what my weblogic-ejb-jar looks like:
<weblogic-ejb-jar>
<weblogic-enterprise-bean>
<ejb-name>Hello</ejb-name>
<stateless-session-descriptor>
<pool>
<max-beans-in-free-pool>100</max-beans-in-free-pool>
</pool>
<stateless-clustering>
<stateless-bean-is-clusterable>true</stateless-bean-is-clusterable>
<stateless-bean-load-algorithm>
round-robin
</stateless-bean-load-algorithm>
<stateless-bean-methods-are-idempotent>
true
</stateless-bean-methods-are-idempotent>
</stateless-clustering>
</stateless-session-descriptor>
<jndi-name>Hello.Home</jndi-name>
</weblogic-enterprise-bean>
I run this through ejbc and package everything up into the EAR file.
However, I get a JNDI lookup failure when I try to access the Bean from
a standalone Java client running on the Windows machine.
Here is the jndi.properties file that I am using:
java.naming.factory.initial=weblogic.jndi.WLInitialContextFactory
java.naming.provider.url=t3://localhost:80
Any ideas what I'm doing wrong here? I can post config.xml also if needed.
Thanks in advance!
Let me try to answer :)....
A1> No need to name diff machines by default weblogic
considers the servers are physically located in diff boxes.
The names are used to differtiate the mang servers which are in
multihomed
Some things to chk
1> Did u targeted the ear file Target as cluster.
2> Can u see on the Admin console that both the man servers
are participated in the cluster( u can see by clicking the monitoring
tab on the Cluster node).
3>Is the URL:PORT for the default web app correct?
the reason: is I dont see the port# on the link u mentioned
4> probably ur ejb might not been deployed on the target thats the
reason u cant access thru java client. If u correct the targets that
will probably fix it.
Hope this helps
Please post the result
Thanks
