Connectivity Webserver with Appserver

What is the exact difference between application server and web server. How EJB interacting between them. Please Explain detaily.

Here is a brief detail:
Webserver will resolved the domain name to the IP. When the user enters either for your site your webserver will run. You can have a site with just a webserver and no application server. Webservers run html files etc and will also take care of SSL for you.
AppServer is used to run EJB, JSPs and javabeans. There is a plugin that goes between the webserver and the appserver. Not all AppServers support EJBs.
Good Luck,

Connection webserver with non webbased databeases

Hello,
I am a student and I am busy with my final paper. It is about webshops for existing companies who wants to start a webshop next to their ordinary business.
Many face as a problem to connect their database or ERP system to the webserver. I notice on this SAP site several forums concerning eCommerce.
I have a few questions concerning this.
-     Is the eCommerce from SAP completely web based, or is/can it connect with non-webbased databases?
-     If so, should that the non-webbases database be a SAP applications or any kind of database?
-     How is the connection been made with the webserver an database. Is a specific software, like XML, being used as interface between the two systems?
-     If the eCommerce from SAP cannot connect with a non-webbases database. What solution would be recommended for Companies to establisch such a connection?
Is there also any documentation available that shows how this works?
With kind regards,
Tjerk Heikens

- Is the eCommerce from SAP completely web based, or is/can it connect with non-web based databases?
SAP E-Commerce application is web based, however, there is no actual database in the web server for this application other than for storing simple application configuration. All the business data comes from an existing SAP backend. The backend could be a SAP-CRM system or a SAP-ERP system.
- If so, should that the non-webbases database be a SAP applications or any kind of database?
The non-web based database or what I call as the backend can either be SAP-CRM or SAP-ERP only.
- How is the connection been made with the webserver an database. Is a specific software, like XML, being used as interface between the two systems?
The web application in question is Java based. To connect to the backend databases, SAP uses a Java Connector also knows as JCo. JCo comes with API to connect to SAP systems and execute function modules and exchange data by executing function modules.
- If the eCommerce from SAP cannot connect with a non-web based database. What solution would be recommended for Companies to establish such a connection?
Some Java based connectors or web services. Though it is theoretically possible to design a 3rd party Backend Layer and connect to non-SAP databases, the work involved may be more complex than developing a new custom Java based eCommerce web application with those 3rd party databases.
Is there also any documentation available that shows how this works?
You can always refer to the [CRM E-Commerce Extension Guide|http://service.sap.com/~form/sapnet?_SHORTKEY=01100035870000647973&_SCENARIO=01100035870000000202&_OBJECT=011000358700000469462006E] which explains in detail the architecture and design concepts.

Hello all
I am trying to integrate sunone6.0 webserver with websphere5.0 app server. I did the following changes in sunone6.0 config files
1) Added one directive to the obj.conf file after "<Object name=default>":
Service fn="as_handler"
2) Added two directives to the end of the magus.conf file:

Init fn="as_init" bootstrap.properties="/opt/WebSphere/AppServer/config/cells/plugin-cfg.xml"
Can any one of u tell me how to check whether sunone webserver is redirecting request to webshere app server?
i tried this url https://sunonewebserver:80/webapps/examples but i was not getting any result of that url.

You might want to check here http://developers.sun.com/prodtech/webserver/

Problem in connecting JSP with Oracle 9i.

Hi,
I am having problem in connecting JSP with Oracle 9i.
I am using windows XP and my JDK version is 1.4. For executing JSP I am using
"jakarta-tomcat-5.5.4-preconfigured". My database name is global.
I have set java_home, j2ee_home, oracle_home, path, classpath as follows:

My code is as follows:
<%@ page language="java" %>
<%@ page import ="java.sql.*"%>
<%
try
DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
Connection conn = DriverManager.getConnection ("jdbc:oracle:oci8:@global", "scott", "tiger");
catch(SQLException e)
out.println(""+e);

What's the disadvantages of using webserver and appserver of different type?

If I choose webserver:iPlanet6.0 and appserver:WebLogic6.1 on one server, What's the disadvantages?
Mayby I will use the webserver and appserver of the same company.
I wish someone give me some advice.

As Barney-15E says, someone with physical control, can just remove the disk, and put it in an external enclosure, and mount the file system with their computer and access all the files.
Only encrypted data would be protected. There are data encryption facilities available on the Mac, both included, as well as 3rd party, including 3rd party whole disk encryption.
But having a password on an account, and engaging the password when the screen saver is active, can keep casual access from happening.
Also if you allow network access (file sharing, remote login, screen sharing), the password will keep random net users from accessing your system, when for example, you are in a coffee shop, or if someone gets onto your WiFi network, or you give a visitor to your home access to your network, or you allow a guest to use the guest account.

Help DSCC agent not communicating with AppServer or Tomcat?!

Installing Directory Server Enterprise Edition 6.3 From Zip Distribution on system running Solaris10 11/08.
Cannot get DSCC to work with either AppServer or Tomcat.
Both AppServer & Tomcat deploy DSEE WAR file and I can look at things that I have manually registered via command line. Cacao agent is running it is just not communicating with AppServer or Tomcat so it cannot commit any actions such as starting and stopping directory instances or creating new directories instances within the web app.
Is this a bug that occurs only when doing a new install using the Zip Distribution?
The Error message I get regardless if Appserver or Tomcat is:
"Could not contact the DSCC agent on <server>. Use the command cacaoadm to check that the DSCC agent is installed and running on port 11169."
I changed to port 11169 because it had a conflict on default port 11162.
Output from cacaoadm & dsccsetup commands is follows:

I started over and installed Glassfish and everything just worked. After the fact I think the real problem was related to the server.policy file. I think this was the problem because using the default appserver 8.2 that comes with Solaris has a different path and I got this same error when tried using tomcat also. When installing glassfish it uses this default path as in the server.policy example as follows so it just worked.
Add the following lines in the {install-dir}/domains/domain1/config/server.policy file
// Permissions for Directory Service Control Center
grant codeBase "file:${com.sun.aas.instanceRoot}/applications/j2ee-modules/DSCC/-"
permission java.security.AllPermission;
Hope this helps some as I was really stuck and confused at the time and just started playing with the stuff. Growing pains. Thanks to those that replied.
Thanks!

Vishal,
Is it the follow of your previous thread ? Re: Issue with PeopleSoft Sign-on url....not able to get the signon page
Wouldn't it be Weblogic11gR1 ?
Did you upgraded your FSCM 8.9 database to Peopletools 8.50 ?
It seems you are not using fixed IP address and /etc/hosts not updated correctly (127.0.0.1 should not be used here).
OS ?
I checked the PSMSGNODEDEFN table and the node PSFT_EP is the default node and not the PT_LOCAL. Can this be the reason or something else? I'm not sure to understand you is wrong there. Why would you want PT_LOCAL ?

Configuring JCo3 Connection Pool with single sign on on non SAP Java server

Hi Everyone,
i have configured a connection pool on JBoss as per JCo3 Documentation and is working great.
Now I need help to configure this connection pool with single sign on so that RFc on SAP ECC systems are executed using end users credential rather than using single user name password used to configure JCo connection pool.
On SAP Java stack I am sure its possible within Java WebDynpro and i assume using JCA resource adapter. But what if we don't want to use SAP Java App server.
Any help will be appreciated.
Thanks,
Divyakumar Jain

My iPhone 5 won't let me use my apps until I connect them with iTunes after downloading ios7. Solutions?

My iPhone 5 won't let me use my apps until I connect them with iTunes after downloading ios7. There's just a thing that pops up and says that in order to activate banners and push notifications I have to connect the app with iTunes. The thing won't go away no matter how many times I push ok, and it doesn't give me another option. Solutions?

Oh my gosh I had the EXACT same problem, and for ages I couldn't figure out how to fix it until today. Here's what I did:
First I went onto my computer, opened itunes, and un-installed tumblr, vine and kik. These were the apps I was having problems with (it said I had them on my phone but, like you, they didn't show).
Then I went to the itunes store, searched for each one, and it said I could update them so I did (just FYI: for tumblr a window popped up saying "please click ok to confirm you are 17 years or older", so I did that also)
When I went back to my phone and tried installing them again (still on my computer), it worked!
I hope this helps, because it was incredibly frustrating. Good luck!

"An error occurred accessing your Microsoft SharePoint Foundation site files" connecting site with SharePoint Designer

I have a SharePoint 2013 environment with 1 AD Server, 1 DB Server and 1 APP Server, with 13 Web Applications running under the SharePoint.
Recently I rebuilted the application because of some infrasctrucutre problems, and I was able to solve all of them, except one. I can't connect to any of those 13 Web Apps with SharePoint Designer. When I try to connect, it always ask credentials, then it
seems like loading the site, then the error appears:
"An error occurred accessing your Microsoft SharePoint Foundation site files. Authors - if you are authoring against
a Web server, please contact the Webmaster for this server's Web site. WebMasters - please see the server's application event log for more details."
I've spent hours troubleshooting it, but none of the information I found was valid. I've already tried to clean the cache, but didn't work. I found plenty of related data of this
error with FrontPage and old versions of SharePoint, but nothing helped. All the Web Apps are SPD-Enabled at Site Collection Administration. I've tried connecting from many different PC's. The 15/LOGS folder doesn't get any data from this error, neither the
Event Viewer.
I really don't know what else to do. Please Help!

I found the answer of my issue was in a .NET Agent installed by NewRelic on the server. I found a connection trouble with Fiddler, then I end up figuring this out:
This can be the result of Real User Monitoring so the first step in troubleshooting would be to disable it and see how it affects the application. The .Net Agent injects snippets of javascript into the header of pages sent to the users browser to measure the
page load time on the user's end.
You can disable RUM by editing newrelic.config and changing this line:
<browserMonitoring autoInstrument="true"/>
to this:
<browserMonitoring autoInstrument="false"/>

Connection issues with Safari 3

I'm having some connection issues with Safari 3.
When I connect wirelessly, Safari won't load any web pages. I go and use Firefox and everything is just peachy.
I've reset Safari, emptied the cache and whatnot. I went in and checked the permissions, everything checks out.
When I connect with Ethernet, there's nothing wrong, which is my dilemma.
Help would be greatly appreciated.

There are a number of posts in the Leopard forum from people with direct experience with upgrading from Panther to Leopard. Here is a relevant thread from there that should reassure you.:
http://discussions.apple.com/thread.jspa?threadID=1418714
Your system should be fine for Leopard, but you will probably need a current version of Photoshop if you don't already have it. See this download:
http://www.adobe.com/support/products/pdfs/leopardsupport.pdf
Also, Leopard doesn't run Classic (OS 9) apps.
One caveat - first make a bootable backup "clone" of your present system onto an external firewire drive so you can recover if anything goes wrong. You can use the "Restore" tab of Disk Utility to make such a clone, and there are also Panther-compatible versions of Carbon Copy Cloner (v 2.3) and SuperDuper (v 2.1.4), both excellent for this.
It's even possible to a create second Panther clone on a different external volume to create a "dual-boot" system, using that volume to continue to run old applications that you can't run with Leopard.

Connection issues with EA4500

I had bad connection issues with my mobile device, so i pressed reset on my EA4500 router, and now when i connect to my network, it gives my limited connection even though i have 5 bars of signal. Not sure what to do now...

Resetting the router will erase all the settings you configured on the router since the initial setup. You manually configure the router's wireless settings so your wireless devices can have internet access again.

Make sure to use a computer that is hardwired via Ethernet cable to the router.

Error 23, 28, 29: These errors may indicate a hardware issue with your device. Follow the steps in this article. Also attempt to restore while connected with the white USB Dock Connector cable that shipped with your device, on a known good computer and network to isolate this issue to the device. The MAC address being missing or the IMEI being the default value, (00 499901 064000 0), can also confirm a hardware issue. Out-of-date or incorrectly configured security software can also cause these errors.

CR2008 connectivity issue with BOE Universes(sap and non sap universes)

Hi Experts !!
Recently we tried to build/connect to a Universe in Crystal Reports2008 via 'Make a new connection tab'.
The universes are of SAP BW or non SAP Lying in BOE Servers and we are trying to build reports on them by conncting/utilizing the universes as a database for Crystal Reporting.
Our issue is most of the time we are not able to connect to the Universes and the connectivity blows out by some 'communication Error' thing initially.
While at some other points in time, the connectivity takes us to the Universe and we are able to select few characteristics and key figures from the Universe but the moment we go futher and try to run by pressing 'OK' button it blows out and say' LOGON FAILED'.
Apparantly, it is an connectivity issue with BOE server and from the different blogs it looks like it is a known issue for long.
The proposed issue resolution were like either CR2008 should be SP2 with BOE SP3 or there should be some additional .dll files defined in the paths in case of MSSQL database. None of this applies to us as we are on CR2008 with SP3 and going back to SP2 is probably not a viable option for us, and we are using Oracle as underlying database in this specific case.( i would like to tell you here that we are able to connect to Oracle Database directly though).
We have raised a message with SAP and was just wondering if we do have some solution/workaround already available to this known issue in place please?
Thanks&Regards.

Hi Amit,
Moved to Universe Forum.
If you have a case logged then no point posting here also, this is a public site and not a case management tool.
Once you do get the solution from your case please post it here also to help others if they have the same problem.
Thank you
