ListFiles in Applet but on the server-site

Hi,
does anyone knows how to get a list of files in Applet which are in folder on the server, where the applet is stored?
Thank you
KarFil

With just applet - No you cannot do that
With some server side component - Yes
You have to have server side component(servlet/rmis-server/ejb) which should be hosted in the same server. This server side component should code to query the files and provide it to the applet.

What is the purpose of "Adobe Credential " in the server site ?

Hi,
I have read some installation pre-requisite in the server site for implement SAP Adobe Interactive form in the FAQ :
1. SAP Web AS 6.40 Java (for all scenarios)
2. SAP Web AS 6.40 ABAP (if you are looking at high-volume print scenarios)
3. Adobe document services (run-time component)
4. Adobe Credential (for creating interactive PDF forms).
could you please give me some enlighteening on the number 4 ? is that compusory ?
Thank You and Best Regards
Fernand Lesmana

Hi Fernand,
4. Adobe Credential (for creating interactive PDF forms).
could you please give me some enlighteening on the number 4 ? is that compusory ?
The type of credential they are referring to in 4) is a Readers Right credential. Basically it is a special file of the form PKCS #12 that you install on your ADS system to enable your users using interactive forms to be able to save data into the form using Adobe Reader. It's a usage rights credential, without which you will not be able to save data in a PDF document. You will need to decide from a business point of view whether it is required or not as it is not compulsory unless you use interactive forms.
You also get other credentials for digital signatures and certification.

How can I change the link color css in one module but not the whole site?

I have a site built in muse but using modules from BC. I changed the link color in the css for the online store and blog but of course it is applying it to everypage. Is there a way to change the link color in an individual BC module instead of the whole site.? I'm new to CSS obviously.
Thanks
Josh

I don't think you can do it right in Muse but you can easily if you have access to the code of the page and the css file.
You need to create a css class something like:
.secondLink a { /* secondLink can be any class name, I just chose that randomly
color: #990000; /* of course substitute your color code in there
Then in your code add:
class="secondLink"
to your link's <a> tag. This will give any links with the class of secondLink the color assigned. Hope that helps get you started.

Why do emails on my Macbook Air take longer than they do to appear on the server site?

When I send or receive an email by clicking on the email icon at the bottom of the screen, it often takes longer to be sent or be received than if I go directly into the internet email site where it appears immediately. At times, some people to whom I have sent emails do not receive them until hours later and conversely, incoming emails appear on the internet email site soon than they appear on my computer. Can this be remedied?

Do you use Navionics for marine a marine chart plotter? I noticed that after I installed all their (lousy) software on my MPB, this Navservice app would start up each time I booted. It took me a while, but I tracked it down to the "LaunchAgents" folder in my system library. Siince I quit the app each and every time I boot my MBP, I decided I didn't need it so I simply renamed the file from "com.apple.NavService.plist" to "com.apple.NavService.plist.old" and rebooted my MBP. Voila, no more NavService app running in the background.
As far as the purpose of this thing, the plist entry is launching the following app:
/Applications/Navionics World/NavService.app/Contents/MacOS/NavService
Take a look and see if you have the same thing.
The Navionics software for the Mac is obviously written by someone that doesnt' understand how Macs really work, and they scattered junk all over the place with their install routines. In fact, if you update the software it will place redundant copies in redundant folders, etc. making it impossible to know which versions are the latest, etc.

Password protecting a page, but not the whole site....

Thanks for all the help so far, site is almost done.
On the website www.kansascrew.com I want to have a members only section. This will allow my rowers to download excuse letters etc. How can I passord protect just that section/page of the website? I don't want random students downloading the excuse letters and turning them in.
Thanks for any help.

You might want to get David Powers book http://foundationphp.com/dwcs4/ work through the registration part and then setting up the pages you want to block, it is done with sessions, a great book to learn how this is done using dw cs4, also you may want to validate your code, it has a number of errors, good luck with your project.

How to set the granted permission in RMI SERVER site

Hi everyone,
I have developin some simple RMi program but the error message is keep on prompting out and I cant really test out what is the result. I understand I got to GRANT the permission for the RMI but I I dun really know where should I start first. I know there are code that can be implement in the sErver site, just hope some one can guide me out.
Thank lot...
here is the code for server:
import java.rmi.*;
import java.rmi.server.UnicastRemoteObject;
public class myRMIServer
public static void main(String[] argv)
System.setSecurityManager(new RMISecurityManager());
try
myRMIImpl implementation = new myRMIImpl("myRMIImplInstance");
catch (Exception e)
System.out.println("Exception occurred: " + e);
Where should i code the getProperties and setProperties code...

so, what u mean is the problem occur doesnt related to coding part ?? do you think it is because I did not start the rmiRegistry, but somehow when i started the rmiRegistry, the console window is blank an it is nothing in the window. pls pls help me to solve this problem... sound easy initially but end up it is not...
by the way, here is the code

Printout from applet varies depending on server

We have always run our web app on Tomcat on Windows, but we're trying to move it to Linux. One small but important component of our site is a simple signed applet that allows users to print out 4x6 packing labels on a thermal printer. If the Zebra (or whatever brand) printer driver is installed properly, the label image lines up perfectly.
Everything continues as normal when the web app is running on a Linux box in our internal/private network, but when the server is our new production Linux server (which is sitting outside our internal network), the image that gets pulled down by the applet is half an inch too far to the right. The code is the same, the Tomcat startup parameters telling it to start headless are the same, the version of Enterprise Red Hat is the same...what could be causing this difference?
I know I'm reaching here, but does it have anything to do with SSL or the applet being signed or something like that? Obviously right now, we don't access that new production machine by DNS name yet--we just hit it by its public IP address (which goes through a BigIP load balancer). I just need to know what in the world to look for!
Thanks...

Weird...that problem was occuring when trying to print with Firefox 0.9.2, but it doesn't occur for IE 6. Both browsers have Java plug-ins associated with 1.4.2 versions of the JRE. This doesn't make me happy at all...that same Firefox browser prints labels from our current Windows-based webserver without a hitch. Why would this Firefox browser move the document/image over half an inch when the webserver was a Linux one, but the IE client browser wouldn't do that? Remember, both use the same JAR for the applet code...

Unable to access gif files from the server

hi all,
i have successfully signed an applet and it is loading in the client system also. in that applet, i instantiated a jbutton as given below:
JButton jb = new JButton(new ImageIcon("http://192.168.91.154:8080/success/set.gif"));
but the icon din appear and a blank button appears, even when accessed from the server system.
if i give the exact path like c:/blazix/webfiles/success/ set.gif, the icon is coming in the server system but not in other systems. i tried without port no also but in vain. pl solve my problem. what i need is how to
specify the path of the file[any file] which is present in server.
or if i put all the gif files in the jar file, can i access the gif files present in the jar file [set for archive] ? if i can, give me the soln for accessing the gif file present in the jar file, so that i need not access the server to get the gif files.(i.e) how to specify the path of the gif files present in the jar file?
i ve one more doubt. the jni library file shld be in the server, and the client has to access the library in the server. i think the applet loaded in the client ll search for the library in the local m/c only . how to make the applet to search for library in the server??
i feel only by using rmi we can solve this problem. am i correct? if so i feel that an appln or applet running in the server shld access the jni library, and the applet in the client side should communicate with this server appln using rmi to get the data.is it correct? is there
anyother way?
i appreciate your help in this regard. thanks in advance. bye, padmanbhan.

Better information on what you are doing with JNI might help you get an answer.
If you have some server process that needs to use JNI, then I would code a servlet to call, instead of using RMI to ge there.
Depending on your environment, and the target audiences environment, RMI may just cause you a lot of grief. Firewalls etc, get in the way of RMI connections and force security holes to be opened in order to work.
If you use a servlet, then traffic to your server process is done via standard http calls, which will already be enabled, because your app runs in a browser.
If ther data requirements are heavy duty, your server could always send an XML stream to the client, which would allow you to describe complex data to the client.
Running JNI stuff from the client directly means a lot of local infrastructure to run your app. The code you want to run, the JNI library ....
If what you have is really an application, but want the convenience of starting it from a browser, look at Java WebStart. Then you can distribute an application via the browser, and WebStart will worry about the deployment issues for you.
In Summary:
Stay away from RMI from applets if you can help it.
If you really have an App, then try WebStart to manage the distribution issues for you.

Clear classloader when exit applet, but not browser

Hi there,
I've got some problems with the classloader.
when i start my applet with the language de, it will correctly name the buttons etc. in german.
in my site it is possible to change the language. after clicking on another lanuage, my applet
restarts with the correct parameters (language=en), but the buttons and so on are still named in
german.
i figured out, that after clearing the classloader cache, the language is the correct one.
how can i clear the classloader cache when i leave the applet, but not the browser?
thanks in advance!

I can not connect to the server

I just installed lion and server lion upgrades. At the beginning everything was fine. I was trying to change some of the parameters of the site. Since i restarted the server it does not recognizes the user/password. It does not open the application. I am logged in as admin. I have even created a new admin user but it does not allow me in. When I hit return the window shakes indicating it does not recognizes the password but how is that possible since I just logged in with that same user and password. The only thing I can think of is that I have changed without realizing the permission for the application to query the system passwords. But I have no idea how I could have done that. One more detail the server site can be accesed as an internet client... so I know it is running.
Guillermo.

Try the following:
1. Turn router off for 30 seconds and on again
2. Settings>General>Reset>Reset Network Settings
3. Reset iPad; hold the Sleep and Home button down until you see the Apple Logo

Document.passivate() giving problem in the server environment

I am having two J2EE web applications accessing PDF forms using LiveCycle API. They both are invoking a short-lived process with RenderPDFForm service that takes form and formdata and renders a PDF form. The code where these applications communicate with Livecycle server is same for both the apps. The applications work fine in the local environment. But in the server environment, one of them work and the other fails with security certificate exception. These applications are deployed to the same server. The application that fails is failing during document.passivate() call. Here is the log message.

The File was generated, but is corrupt . Don't Open the file, It's wrong.
When I use the function GUI_DOWNLOAD the file is generated right. But in the server not.
Can someone help me please ??

Logout works fine on Local Machine but not on Server

I have the following code in my backing bean:
      ExternalContext external =
        FacesContext.getCurrentInstance().getExternalContext();
      HttpSession session = (HttpSession) external.getSession(false);
      session.invalidate();
     // redirect using response because logout is a HTML page
      HttpServletResponse response =
        (HttpServletResponse) external.getResponse();
      response.sendRedirect("../logout.html");The problem is that this works fine on my local machine http://localhost:8888/my-context-root
but on the Server clicking on the Logout link gives Page cannot be displayed.
The protocol is https://ip-address:port/my-context-root and on the local machine it's http
Is it the https thats causing the problem ?
I also tried using:
external.redirect("../logout.html"); but this also didn't help.

The URL for Login is
https://ip address:port/my-context-root/restricted/home.facesWhen the logout link is clicked the same URL is rendered.
Backing bean is
public class HomeBackingBean
public String logout()
    try
      ExternalContext external =
        FacesContext.getCurrentInstance().getExternalContext();
      HttpSession session = (HttpSession) external.getSession(false);
      session.invalidate();
      //FacesContext.getCurrentInstance().responseComplete();
      Utility.logDebug("Session invalidated, trying to redirect to logout.html");
      // redirect using response because logout is a HTML page
      HttpServletResponse response =
        (HttpServletResponse) external.getResponse();
     response.sendRedirect("../logout.html");
    catch (IOException ioEx)
      Utility.logDebug("Failed to logout due to IOException");

ACE: if one server is loaded and it want to use the server not loaded? how?

Hello,
I have 2 real Servers (10.24.8.200 and 10.24.8.201) in loadbalance (HTTP and HTTPS) with VIP 10.24.16.10, and the type of loadbalance is round robin, but when the server (10.24.8.200) has high proccessing for example memory or hard disk and users try to access to server (10.24.8.200) this is more slow. if this server is too loaded? how can the ACE switch to another real server? in 10 seconds for example?

If your server is running an SNMP agent, the ACE can use SNMP to pull stats from the server. You'll just need the correct OID. For instance, if you were using Linux, you might use something like the following as a probe:
probe snmp linux-stats
interval 10
community public
oid .1.3.6.1.4.1.2021.10.1.5.1
threshold 75
.1.3.6.1.4.1.2021.10.1.5.1 is the OID for CPU load average (for Linux, Windows would have a different OID). If it goes above 75, the server is marked as out. When used with the least-loaded predictor, it will also divert more traffic to the least loaded server, as defined by that OID. You can use multiple OIDs in conjunctions and give them different weights.
However, judging from your timeout value of your get-http health check, I would check to see if the issue isn't that your servers are flapping because of a too-low receive threshold. Each server has 2 seconds to respond to the ACE, which may not enough time given that the servers may be getting a lot of traffic and you're doing these checks every 4 seconds.
If one fails, the other gets all the traffic, until it is overloaded, and it fails. By this time, your other servers has calmed down, and gets all the traffic, and the cycle repeats itself. Check SNMP traps or SYSLOG to see if this is the case.
Either way, you might want to change the timeout to 5 or 10, to give them more breathing room.

Rollback is not working when "The server threw an exception" error

Hi
These are my transaction steps
1) Call the StartTransaction method of the company object (Function AA)
2) Add Goods Issue (Rollback if error occurs) (Function BB)
3) Create record with oRecordSet object (Rollback if error occurs) (Function BB)
4) Add Journal Entry (Rollback if error occurs) (Function CC)
5) Add Goods Receipt (Rollback if error occurs) (Function DD)
6) Create record with oRecordSet object (Rollback if error occurs) (Function DD)
7) Call EndTransaction (with commit) to complete the whole process (Function AA)
These are working fine usually.
But problem is when user has "The server threw exception" error message.
Whole transaction must be rollback but still step 2 and 3 records are exist on DB.
Rollback is working fine with another error messages.
I programmed call Rollback transaction if calling function has any error.
Function BB, CC and DD are calling from Function AA.
I never have "The server threw an exception" error on my development machine with B1 2005 PL 51.
This is happened only LIVE server with B1 2005 PL 51.
B1 was upgraded from PL29 to PL51 recently becaseu of Locking issue.
Then Locking issue was solved but have "The server threw an exception" error and rollback is not working properly.
I hope someone can help me!!!!.
Thank you
2) & 3) steps

Hi Joanne,
There are 2 things to check here.
1. is the Transaction
2. is the RPC_E_SERVERFAULT.
for the first one,
in step 2, just before you add the Good Issue, can you try to check first if you are still in a transaction ?
Just to make sure.
If it is, maybe you should open a ticket to SAP support.
BTW, Which version is your Live environment ?
for the second one,
try to search the error in this forum. there is a lot of posting about this.
The problem might also go away if you upgraded your SBO.
Please search and see if there is anything the same with your problem.
Regards
Edy
