How is better to connect, use a class or ..

hi,
i have a web application with ten classes. I hava a class DatabaseClass which provides only the connection to the database with a method call getMyConnection f.i.
I thought to remove this class and put the databse conncetion
String(server name,database name ,user,pass..) to the web.xml file and let other classes to call this parameter from web.xml and make own connnection instead of to create an instance of DatabaseClass. What could be a problem, what is advantage, disadvantage.?
thanks

I don't know, it's your idea.

How can I make server use single class loader for several applications

I have several web/ejb applications. These applications use some common libraries and should share instances of classes from those libraries.
But applications are being deployed independently thus packaging all them to EAR is not acceptable.
I suppose the problem is that each application uses separate class loader.
How can I make AS use single class loader for a set of applications?
Different applications depend on different libraries so I need a way that will not share library for all applications on the domain but only for some exact applications.
When I placed common jar to *%domain%/lib* - all works. But that jar is shared between all applications on the domain.
When I tried to place common jar to *%domain%/lib/applibs* and specified --libraries* attribute on deploying I got exception
java.lang.ClassCastException: a.FirstDao cannot be cast to a.FirstDaoHere http://download.oracle.com/docs/cd/E19879-01/820-4336/6nfqd2b1t/index.html I read:
If multiple applications or modules refer to the same libraries, classes in those libraries are automatically shared.
This can reduce the memory footprint and allow sharing of static information.Does it mean that classes should be able to be casted ?

You didn't specify which version of the application server you are using, but the config is similar as long as you know what to look for. Basically, you need to change the classloader delegation. Here's how it is done in 8.2

How to create database connection using DB2Driver in JDeveloper 10.1.2.1.0?

I am trying to create a JDeveloper/Data Connection using com.oracle.ias.jdbc.db2.DB2Driver. The driver is registered from a User Libraries: DataDirect JDBC. I have the following class path for the library:
E:\DataDirect\3.4\lib\YMdb2.jar;E:\DataDirect\3.4\lib\YMbase.jar;E:\DataDirect\3.4\lib\YMutil.jar
I have no trouble configuring the connection but when I test it and I got No suitable driver Vendor code 0. Whats wrong? I have successfully created several database connections using Oracle thin driver. This is first time I am using a third party driver. Has any one successfully create a database connection using the com.oracle.ias.jdbc.db2.DB2Driver?

Hi
Since the error points to the unavailability of the driver class,can you double check your library claspath entries again.
I just tried a DB2 connection using the following properties and the connection went through fine:
Driver class name: com.oracle.ias.jdbc.db2.DB2Driver
URL: jdbc:merant:db2://<host_name>:50000;DatabaseName=SAMPLE

How to debug RFC connection using RfcOpenEx?

How to share internet connection using socketserver?

Hello guys is this possible? i want to share my internet connection programmaticaly using java for example i have a one computer that has internet connection and i want to run socketserver from the computer that has internet connection and share the internet connection to another computer that has no internet connection using socket how to do that in java?

How to share internet connection using 10.6 Server

Hi
My server connects to the internet via ethernet and I'd like to setup something like internet sharing so that I have a WiFi connection in the same office as the server.
I read how to do this using Gateway Setup Assistant but I already have a DHCP setup with lots of static maps and have no wish to overwrite all that.
I've turned on NAT and attempted to create a new Subnet using DHCP but it doesn't offer me Airport in the network interface menu (only en0 and fw0). Airport is turned on in network system prefs.
Hope someone can help.
Cheers
James

I've turned on NAT and attempted to create a new Subnet using DHCP but it doesn't offer me Airport in the network interface menu (only en0 and fw0). Airport is turned on in network system prefs.
Have you actually configured the AirPort network with its own IP address settings (in a different subnet from the wired ethernet port)?
Having the interface enabled isn't enough to make it a viable gateway interface. It needs an IP address/subnet mask too.

Dear Abapers.
I'm using SET_TABLE_FOR_FIRST_DISPLAY method from CL_GUI_ALV_TREE class to display a report in an ALV Tree and I need to display the footer.

How to share internet connection using 5G wifi/channel 36~48

I'm using a 15 inch late 2013 MacBook Pro with retina display running 10.10.1 and iPhone 5S A1530 running iOS 8.1.
I use an Apple thunderbolt to ethernet adapter at work for internet and it's all cool and fine.
The problem comes when I try to share the internet connection with my phone through wifi. It's alright if I use channel 1 to 11. But when I try the 5G channels: 36, 40, 44, 48, it just doesn't work. The wifi icon in the top right corner of my screen has a wave animation and then nothing. It just goes back to grey instead of an arrow pointing upwards. In the slimmest hope of a display error, I search nearby wifi signal with my phone and nothing.
I have a 5G router at home and both my laptop and my phone can connect to its 5G signal. So the hardware should be fine.
It's weird since it should be working as Apple decided to put an option there for user to choose from all the channels, among which lie the four 5G channels.
So to conclude, my laptop with a functioning 5G wifi module can share internet connection through 2.4G wifi but not 5G.
Hope someone could help me with it. Thanks.

How different Web Services can use a class which parses an XML file

I am using RAD6.1 for developing and deploying web services.As I am using 15 web Services which uses a common class which is used to parse an XML file.As this XML file should be parsed only once and should be used by all the web services.I have made this common class as Singleton but it works as singleton for only one webservice and for other web service again it is parsing the xml file.I want to parse this xml file only once and used by all the web services.In my case tis file is parsed 15 times for 15 web services, but it should be parse donly once and used by all 15 services.Please give me the solution.
Thanks and Regards
Sayeeduzzaman

Hello,
the 15 Webservices should have a static attribute which contains the xml:
private static String xml;
then initialise the xml like this:
if (xml == null)
xml = parseIt();
else
//do nothing, XML already initialised!
}

How to configure https connection using a http proxy in weblogic server

Hi,
I have a proxy in Aqualogic Service Bus that points to a https external service. Our development environment internet access is supported by a http proxy server. The ALSB proxy fails to connect, with the following error message:
<con:fault xmlns:con="http://www.bea.com/wli/sb/context">
<con:errorCode>BEA-380002</con:errorCode>
<con:reason>
Tried all: *1 addresses, but could not connect over HTTPS to server: sitenet43.serasa.com.br port: 443*
</con:reason>
<con:location>
<con:node>RouteTo_ConsultarSerasa</con:node>
<con:path>request-pipeline</con:path>
</con:location>
</con:fault>
I've added the following parameters to jvm args:
-Dhttp.proxyHost=10.128.0.50
-Dhttp.proxyPort=3126
-Dhttp.proxyUser=<someUserName>
-Dhttp.proxyPassword=<somePassword>
Accessing the page in Internet Explorer or Firefox is working fine. Somebody knows any additional configuration to this case?
Thanks in advance
Rogério Cruz

In osb you can configure a HTTP proxy server. Once this is done all BS http/https requests will be through the configured proxy server.
