Strange classpath problem sharing jars betweens webapps

I'm using tomcat 4.1.31 and I have 2 web applications using struts.
The first thing I see is strange is that if I put struts.jar in the tomcat/shared/lib directory when I load the application it sais it cannot instantiate the objects that inherit from the struts' classes. So I put struts.jar inside each application /WEB-INF/lib direcotry and it works.
The same happens with one jar i want to share between applications. Since it depends on struts.jar I cannot put it in the shared/lib dir. I have to put it in every application's lib. But I get class cast exceptions when I go to one app after I've been browsing the other since the shared classes were loaded with different classloaders and they are not the same class as expected.
Is this related to the webapps not being deployed as war files but copied uncompressed to the tomcat/webapps dir.?
If I load all the classes in the tomcat classpath everyhing works perfectly.

I suspect some other problem.
NT allows variable values up to 1200 characters. There are no size limits on the env space (of course excluding actual memory.)
And what you printed included 'windows' which was not in your string to start with.
How are you adding to the var?
And how are you printing it out?

Problem: Sharing session between two different Web browser & Web Appn'

I�m facing a strange scenario here and would appreciate any inputs which could resolve this issue.
I have two webapplications (EAR�s) on two different machine and different WebSphere application server. I have �WebAppA� [on machine A, WAS A] which opens in parent window and expects to pass some info in the FORM submission with request parameter to �WebAppB� [on machine B, WAS B] which opens in a child window browser on clicking submit button from �WebAppA�.
Now the WebAppA is required to wait till the response come from WebAppB after certain functionality and once the function of retrieval is over by WebAppB, it sent back the response data back to WebAppA FORM, which finally submits this form after getting the response data from WebAppB. Now the response to WebAppA [which is in machine A, WAS A] from WebAppB is a pure POST request on complete URL and set of request parameters with values.
Now what is happening is that, when a User A fills the form on WebAppA and submits the data to WebAppB, on response it gets the data of some other User request, for example day of UserB or UserC.
Now when I do the test on my development environment, where its just me or some other 2-3 users accessing it I don�t face any problem. I get the response for the request I have submitted�.PERFECT. On production I have issue where users are getting data as response of other users.
I suspect since the response is submitted to the form page of WebAppA its unable to synchronize to which user it belongs to. May be that�s the reason when I test it on development with single or 2-3 users its behaving fine. I hope I could put my question properly to you. I don�t know what can resolve this or what is the actual cause? Is there a proper way to implement this? Please any suggestion or inputs are appreciated.

Thanks Amittev,
That's the problem for me. Actually this is a part of integration with third party application (which is loaded in child window - WebAppB). So as per the functionality there is no reference or trace of the user in the parent window at first instance. Anyone can come to parent window and initiatate a process. Its only when the data comes back from child window (which is the WebAppB), that parent window application (WebAppA) take the response and proceed further. Now here is what I'm facing problem. the user who initiated the process by clicking on the submit buttom of Parent window is not getting his response, but of some other user. This is not happening with every user and at all time. But were sparingly and rarely, but enough to bring headache to our department now.
Now I suspect that, since there is a parent/child browser functionality here the session which is started by parent is not synced with child where the WebAppB is loaded and responds the response to WebAppA. The WebAppB makes a POST request submission to the WebAppA thru the child window and the session here is missing synchronization, I believe. I will appreciate some inputs and resolution to this problem. Thanks.

Problems Sharing Files Between iMac's

I've created a network between my to iMac's, and I'm using one of them as a server-
I've created a folder, inside "Public" folder and I've turn "File Sharing" on and done all that it said.
Selected the folder, and everything.
When I go to my other iMac, I connect to the network with no problem, I see the folder but can modify anything from the iMac that is NOT the "Server".
I've check everything about the "read & write" at the bottom of the folder, and still doesn't work.
Can anybody help me ? I really need this working ASAP.
Thanks to all, and happy new year !!!
Esmeralda
PS: It's better if I buy a external drive and use it attached to one of the iMac's ? Thanks.

If I understand this correctly. You are using file sharing to do this. And going to connect to server to get access. In file sharing while connected to your home computer they only have read only access. They can drag you apps. to their desktop and copy or modify it, but not on your computer. They can listen to your music . whatch your videos read your mail and use your printer or dvd drive. If you give permission to all. In file sharing there is an xgrid check off which allows users to work together on apps. If you check the xgrid and then the ? in file sharing it tells how to do this.

Problems sharing music between libraries

I'm having trouble sharing music from my computer to my wives computer on the same network different apple id's. This was never a problem in the past. has there been any changes to prevent this?

Whilst you can share the content between two different libraries using a different Apple ID for the iTunes login, they both need to use the same Apple ID for homesharing (iTunes > file > homesharing)

Problem Sharing Variables between 2 machines

I am having problems trying to create a project that would share variables between multiple computers. I am using Labview 8.2.1 (I am new to 8.2.1 and Shared Variable).
here is what i did:
1. I created the project with Client and Server VI's and a library containing shared variables, which both of them call
2. I placed this project onto 2 computers (XP on a local workgroup, no firewall, see each other).
3. On one of the computers I bound all shared variables to their counterparts on the other computer
The system is "almost working"
The problems are:
- I initially used wrong type variables for few items. I then modified the variables in both VI's and Shared Variable libraries and repeated the Steps 1-3 above.
But the sysrtem has some sort of a buffer somwhere, because it keeps bringing the old types of shared variables back (when I monitor them using Shared Variable Monitor).
- When I do binding to source, the system shows wrong variable types (for example DBL instead of U8).
- It takes almost a second to write and read shared variable (my network is quite fast)
I saw that the Labview Example with Server and multiple Clients uses 2 sets of shared variable and they bind - separate sets (different names) fro client and server within the same project. Do I have to do this or is this done just to simplify bindinga nd future distribution?
Is there a buffer/setup/file that I need to clear to get rid of "old" shared variable assignements? (I tried undeploy/deploy - does not help...)
Thank you very much,
Gleb.

Hi Gleb,
It sounds like the shared variable is not getting completely undeployed from the shared variable engine. I would recommend opening the shared variable manager and undeploying the library from there just to see that it is no longer in the engine. Then, redeploy the library and rebind your variables to the host library that you have deployed.
It is not necessary to have different sets of variables for client and host. The important part of the variable is what it is bound to, not necessarily what it is named. So just undeploy your variable, double check the settings of the host variable, then redeploy using the variable manager and rebind your client variables.
I hope this helps,

Strange Battery problem, keeps switching between 99%/100%

My battery keeps flashing between being at 99% and 100%. The Amber/green light on the power adaptor also keeps flashing green and amber.
What could be causing this. I have all the latests updates as far as i can tell. Anyone have any ideas?
I also did just get my MacBook back from apple. The hard drive died and they replaced that.

hello cameronjmulder,
I had that problem with my macbook previously too. I searched through the forums and i found that the people who had that problem were able to get it replaced (the battery) with apple. I got my battery replaced (with a new one i believe) and it no longer does it. I don't know if there is a fix apart from simply replacing the battery
You should either call applecare or head over to an apple store. Though depending on their supplies, you may have to leave your macbook there for a while. perhaps you can call ahead and ask.

Problems sharing libraries between a Mac, and a Windows.

Ok.
So ive been doing a fair amount of research on the subject.
Havent found much, so i decided to come here to see if any of you guys might help.
Anyways, the i want to share my libraries over the network. So, the 2 computers are both connected, they see eachother, the libraries show up, but when played, everything is skippy, and cuts in and out.
I checked everything.
The connection is fine as far as i can see.
I have a linksys WRT300N router, and i even upgraded the firmware on it.
So, is there any sort of fix for this sort of problem?

no help?

Problem sharing media between multiple users on same Mac

My wife and I have an eMac, running Mac OS 10.4.11, with iTunes 9.2.1(4). We each have separate user accounts. Previously, I had imported several albums into my iTunes library. Now, my goal is to be able to share the albums that I had imported with my wife. Simultaneously, our available hard drive capacity is getting limited, so I decided to put my iTunes media on an external fire wire drive by Iomega. I followed article HT1449, transferring my media (and, not the other associated library files) and that part, at least, seems to be working fine. The folder "iTunes media" is now located on a partition of the external drive. As far as I can tell, both my wife and I have "read and write" permissions for this partition. Ownership of the partition volume is "ignored".
Now, as for setting up my wife's iTunes library and linking it up to the iTunes media folder on the external drive, I have followed HT1203 as a guide, changing the path of the media folder to the partition on the external drive. But, it simply doesn't seem to have any effect. There are no songs available within iTunes from her user account.
I would appreciate any guidance on how to resolve this. Thank you.

Chris, won't this copy the music contained in the external media folder, to the media folder under his wife's account?
They are both using the same media folder so iTunes won't copy it anywhere.

Session Sharing between Webapps

          Hi everybody,
          I have read that session sharing between webapps is possible since Wls 6.1 using
          the same name
          for a cookie in the webapps.
          I have created a webapp named myPortal (for example) and a second named Navigation.
          The first webapp
          includes content of the second webapp
          After deploying the webapps in WLS and printing out the sessionid in each of the
          webapps, I found out
          that unfortionally the sessionid in the two webapps are not identical.
          My Question is: Is session sharing possible, or should I create a workaround?
          Here is my environment:
          WLS 6.1 on SUN running in developmentmode
          two webapps, deployed as .war file and/or as .ear file
          Cookie Name is configured to be identical in the two .war Files
          Regards,
          Ed


Search this newsgroup for a reply post on this by me. I incorrectly went down the
          primrose path on this one, too. I was corrected by Cameron Purdy. I did a bunch of
          impirical research on this and came to the same conclusion you have come to. The spec
          doesn't require it and, in fact, says that separate webapps have separate contexts, so
          they don't share sessions, even if the cookie is the same name.

Problem setting up shared printer between PC and Mac with 10.6

I am trying to setup a shared printer between my Mac and PC. I have a HP K80 attached to my PC (which has Vista Home Premium). I have a Macbook pro with 10.6. I have shared the printer on the PC side. From the Mac I have added the printer via Windows Printer sharing, but for some reason I cannot print to the printer. Everytime I try to print, the job just pauses. Is there something I am doing wrong?

Thanks I installed the gutenprint drivers and tried this, and now all working:
http://guides.macrumors.com/Printingto_a_Shared_PCPrinter
Printing to a Shared PC Printer
This article describes how to print from Mac OS X to a shared printer connected to a Windows XP machine. It assumes the computers are already networked and that you can access the PC's files. These instructions are relevant for Mac OS X 10.2 upwards. The instructions may work with Vista. I don't have the means to try it.
1. Find the IP address of your PC - go on Start > Run. Type in cmd and click run. Now type in ipconfig /all and hit enter. This should give you the machine's IP address.
2. Share the printer. Open up Printers and find the one you want to share. Right-click and choose Share. Now click the 'Share this printer' radio button. Now choose a sharing name. Keep it simple - e.g. HP, Office, PC etc.
3. Open a web browser on your Mac and type localhost:631 in the address bar
4. You should now have the Common UNIX Printing System web interface up. Click the 'Add Printer' link.
5. Type a name for the printer, making sure you don't include /, # or space characters. Click continue.
6. Select Windows Printer via SAMBA from the Device list and click continue.
7. For the URI, you need to include a username and password for an account on your PC. You then need to enter a URI in the following format: smb://username:password@ipaddress/printer. So for example smb://johndoe:[email protected]/HP
8. Choose your printer's make, or if you have a PPD file for the printer, choose that. Click continue and choose your printer's model. Now click Add Printer.
9. Done! You now have a list of options for changing the various properties of the printer.
You don't need to be on the same workgroup or domain as your PC, just the same subnet. If both your Mac and PC are connected to the same router, either wired or wirelessly, then you should be on the same subnet.
Thanks guys

Custom classpath and custom jar entry in R12

Hi all,
I have created the custom classpath and custom jar file for isrore process. I had put custom jar and custom class entry in orien_application.xml file. But it was working on R12 at doveloper mode. It will creates the classes for custom jsp file using custom import class or custom jar. But once i revert back the devloper mode means it won't work.
Could you please help..

Oracle apps R12 - Compiling JSP with custom classpath
We all know that to compile JSP manually on the Oracle Application R12 instance, we need to run the file $FND_TOP/patch/115/bin/ojspCompile.pl.
Its help is as follows:
syntax: ./ojspCompile.pl COMMAND {ARGS}
COMMAND --compile               update dependency, compile delta
--create                rebuild entire dependency file
-delta.out update dependency, list delta to file
-dep.out update dependency, output heirarchy to file
ARGS -s matching condition for JSPs filenames
-p number of parallel compilations
-log to override logfile from ojspCompile.conf
You are
recommended to set the log file location
outside of any network file system shared (NFS) area/drive.
-conf to override ojspCompile.conf
--retry         retry previously failed compilation attempts
--flush         forces recompilation of all parent JSPs
--quiet         do not provide an actively running progress meter
--fast          instantly fail jsps that are possibly invalid
example1: ojspCompile.pl compile -s 'jtf%' -p 20 retry
example2: ojspCompile.pl compile -s 'jtflogin.jsp,jtfavald.jsp' flush
example3: ojspCompile.pl compile fast --quiet
If your JSP uses custom classes, then compiling jsp manually can fail if proper classpath is not set. Yes, even though if you have setup the classpath correctly in orion-application.xml, it will fail because this jsp compile utility does not read orion-application.xml classpath.
So, the problem is to identify where to set the classpath so that above utility can pick it up. After several search and looking into code, I found following:
By default, the jsp compiler script uses following configuration file
$INST_TOP/appl/admin/ojspCompile.conf
This conf file has a classpath field in it which is usually pointed to file
$INST_TOP/appl/admin/ojspCompile.properties
This property file lists the classpath used for JSP compilation.
So if your classes are not listed in this file, your jsps will not compile by ojspCompile.
Ofcourse, you can always set the "main_mode" to "recompile" in orion-web.xml, but that for production you do not want to change it and compile the JSP on file deployment.

Strange Classpath behaviour in AppServ 8.1

A tricky thing but give me some headache.
Recently, I'm trying to use Sun Application Server 8 2005Q1, and i got this strange classpath behaviour.
here is the problem.
My application is using some third party jar file. So I have to set up my classpath to this jar files, which is in my instance JVM Setting>Path settings. However, when i am going to deploy it, It returns me with an exception which mean, It can't find those 3rd party jars.
the strange thing is, if i put the path into server-config, JVM Setting>Path settings. It will deploy happily ever after.
so any idea why i got this behaviour? and is there any way to do it without disturbing my server-config?
thanks for your time....
cheers,

Hello there - how can I share my iTunes library between two users on the same computer? I put the library in a shared folder between both and have selected this library on both as well, but when I update iTunes with music etc it only appears on one?

Hello there - how can I share my iTunes library between two users on the same computer? I put the library in a shared folder between both and have selected this library on both as well, but when I update iTunes with music etc it only appears on one?

Thank you Joe - I tried this but it's only showing a teensy amount of music - the stuff on the second users account as opposed to the giagntic library on the 'main' account. I actually went to a Genius Bar and they said that apple doesn't really want you to share music between accounts - parents don't want to hear their kids music etc. Which seemed strange, but it might be the case sadly Thanks anyway!

Sharing information between tiled view and view bean

I have come across one more problem. I have a search result
page. This search result page has a static text field and a repeated group
(I simplified the page description, for explanation purpose). In the NetD
implementation they are maintaining a page level attribute (say boolean
haveSenisitiveCustomers) and setting this attribute in the
afterDataObjectExecute event. (This data object is associated with the
repeated). In end display event of static text field, they are displaying
message say " due to Registration type, not all customers meeting the
criteria are listed") if the haveSensitiveCustomers flag is set.
After Migration, the boolean flag and static Text Field movedto
SearchResultViewBean and afterDataObjectExecuteEvent has moved to
TiledViewBean. Actual processing done is more complicated than this
explanation. However, it boils down to sharing information between
tiledViewBean and its parent bean. How do we achieve this in the Migrated
Application?
One way is to add getter methods in the child tiled view bean( to
access in parent view bean, call getRepeated1 and cast to the actual type
and invoke the get methods)Probably the typical solution (I say typical because I don't yet know) will
be to do what you suggest: provide methods between views that can be used to
determine the state needed for processing like this.
However, let me alert you to something that's different than ND, and which
may cause you some trouble. In ND, all retrieving DataObjects associated
with a page executed at one time, and the afterDataObjectExcecuteEvent fired
before any display processing began. However, in JATO, tiled views are
independent objects, and any models associated with them only execute when
the tiled view is first displayed.
Therefore, if the static test field you refer to appears in the page before
the tiled view, then the tiled view will not have executed its associated
model before the static text field is rendered. You will never see the
static text field display the text you want because you won't have the
information at display time. (If the text field appears after the repeated,
then it's not problem, as the display of the tiled view will have executed
the associate model before the field displays.)
The solution is to manually reference the tiled view and its associate model
before they would normally execute. You would execute the model and set the
tiled view's setAutoRetrieveEnabled() to false to prevent it from executing
the model a second time. Perhaps the easiest thing to do would be this:
beforeStaticTextDisplay(...)
// Force the tiled view to execute the associated model
Repeated1TiledView tiledView=
(Repeated1TiledView)getChild("Repeated1");
tiledView.beginDisplay();
tiledView.setAutoRetrieveEnabled(false);
Although the beginDisplay() method will be executed twice in this case (once
deliberately, above, and later during actual display), there should be no
overhead. The beginDisplay() method doesn't do anything anyway except
execute associated auto-retrieving models and fire the
afterAllModelsExecute() event.
Mike, do you concur or have any comments?

Very Strange Internet Problems

I own a MacBook Pro 15.4 Inch that I purchased about a year and a half ago. I recently upgraded to Leopard and have all the latest updates. I am from the US, and when I am home my internet works fine. However, I am on travel to Seoul, South Korea right now and am having a very strange internet problem.
As far as I can tell, the URLs that I type in to my browser are, sparodially, not translated correctly into the webpages that they are supposed to represent. This problem is probably effective 75% of the time, and the rest of the time my internet works roughly correctly. For instance, when I enter http://www.google.com, instead of being taken to the Google homepage, I am taking to the homepage of Jammin Beats DJ Service, an obscure website about a company in northern Pennsylvania. The actual URL of this website is http://www.jamminbeats.com, but when my internet is malfunctioning, 'jamminbeats' is for all intensive purposes replaced by 'google' (that is, it applies not only to the main page, but to sub pages, so "http://www.google.com/weddings" takes you to "http://www.jamminbeats.com/weddings" and etc). For most other webpages, one of two things happens. Either I am taken to the correct page but it is displayed without any images or frames (just the html text and links), or I am taken to a blank page with the header "Under Construction", which I assume is the default for a page that doesn't exist. This is why it seems as though the URLs are simply being interpretted erroneously.
This problem occurs when connecting both to the wireless and the wired internet at my hotel, and it occurs on both Safari and Firefox, so it is not a connection-specific or browser-specific problem. It may be a problem with the hotel's internet, and as of yet I have not had a chance to test the computer at another location. However, a colleague using an IBM computer has had no problems, and I am currently on a Samsung machine in the business center of the hotel and it is working correctly as well. I have searched extensively online for a similar problem but have come up empty handed, and more than anything, I am confused about what might be causing this problem. The strangest thing is that a fraction of the time, the internet functions normally, but it is usually roughly 15 minutes out of every hour, and eventually I am inevitably taken back to Jammin Beats.
I am a computer science graduate but I still have no idea what would cause this problem. At first I thought it might be a hacker, but if it is, he or she has been at it consistently for 3 days now, and only seems to be targeting my computer. Any ideas or solutions would be greatly appreciated, as I have been forced to resort to the hotel's business center for checking email, doing work, etc. Thanks in advance.

I did consider that, as I was in Beijing last week and there are a number of censored sites. However, in Korea I have had problems with very basic sites like facebook, wall street journal, google, yahoo, Korean google, my hotel's webpage, etc. Further, I have successfully gotten all of these sites to load seemingly at random, and can access them without problems on other computers. The only disconnect seems to be between my MBP and the internet, not between Korean internet and the web. I have toyed around with the network settings, and although sometimes after switching from "Automatic" to a fixed connection I get some sites to work, it usually only lasts a short time and eventually the same sites stop working. I reset my cache regularly to make sure I'm not getting sent to cached sites, but this also doesn't help. Further, my Apple Mail, Skype and AIM accounts jump between being connected and disconnected randomly as well. Again, this is isolated to my own computer, which is why I'm so confused.
