Using OCI driver with Tomcat for JSP?Servlets

We have a need to switch to OCI drivers instead of JDBC thin driver. Our tomcat is running on Sun and Linix platform. Does anyone have real world experience in terms of configuring the OCI driver and connection pooling? Please help to provide some configuration tips.

You should repost this in the JDBC forum here on OTN so that you can get some better expertise in this area.

Hope this helps,

What is the best editor to use for JSP/Servlet?

Hello,
What is the best editor to use for JSP/Servlet database development.
I'm looking at Dreamweaver,Java Studio Creator.
I want some thing fairly easy to use that has database helper wizards like dreamweaver.
Thanks for the help.
Frank

Is it better to have a servlet do the database work and call it from JSP?No, it's better to have persistence objects do the database work. Servlets handle HTTP requests, and JSPs are HTML factories that should be pure view.
But there are lots of ways to do things. You just have to understand the tradeoffs when you decide.
I do not want to hammer out code, I want to learn the
best way to do things from experienced developers. Sorry, sounded like you just wanted to churn stuff.
"best way" can be subjective. In one app, "best" might be "delivered fastest". For another, "best" might be "most secure" or "most easily modified" or "best performing" or whatever. You won't get a "best" answer, only different choices. And they aren't always so easy to explain or execute.
I'd recommend that you start by reading about layered applications (3-tier architectures) and MVC separation. Once you've Googled enough about that, look into a framework like Struts or Spring or WebWork. That'll help you figure out where to put each responsibility in your app.
I can use dreamweaver to create web apps, but I hate
the arrays used to define fields. It also seems not
to take advantage of connection pooling.Don't know what you're talking about here, Frank. What do fields have to do with connection pooling?

What is the plugin used for jsp/servlet development , deployment in eclipse

what is the plugin used for jsp/servlet development , deployment in eclipse?
can some body tell me what are the other plugins to be used in enterprise java developement
is eclipse would be a best choice j2ee application development?
thanks

what is the plugin used for jsp/servlet development ,
deployment in eclipse?There are several J2EE plugins I think. One is Lomboz.
can some body tell me what are the other plugins to
be used in enterprise java developementPfft...
1) Might depend on what you're doing. J2EE is not just JSP, you know?
2) Why do you ask about Eclipse IDE at Sun's Java Programming forum?
3) Do you really want me to list the 5000 plug-ins someone might use for J2EE-related development?
4) Open fucking Google and search yourself
is eclipse would be a best choice j2ee application
development?IMO: no. Simply because you have to look for J2EE plugins. I'm too lazy for that. Though it has other benefits that might outweigh the plug-in-searching issue.

please help me in sloving this problem
my global database name and SID value in mohan
Thanking u

Bathina,
Your problem is in your URL:
String url="jdbc:oracle://oci8:/@mohan";As far as I know, you can't use the forward-slash character ("/"), by itself, as your database login name -- you must supply a "login/password". I don't know why, and if you don't like it, I suggest you create a TAR (Technical Assistance Request) via the MetaLink Web site.
I recall similar questions being asked in this forum -- have you tried searching the forum archives?
Good Luck,
Avi.

I am using JBOSS 1.6 with oracle 11.1.0 and jdk 1.6
Please help me resolve the problem
Thanks,

You should confirm that you can connect to the DB with a simple Java class using the url that the code you posted is using.
This will show that the OCI client is installed and executing properly. If you can't connect externally you will need to fix that first.
Is the Oracle client installed on the same machine the JDBC code is running on?

Different Classloader for JSP, Servlets?

Hi!
          Does the WL5-JSP-servlet use an other classloader then the other
          servlets??
          I've previous posted an article with the subject "JSP - Servlet - Static
          Code in Classes".
          I will try to describe my problem better:
          At server startup I pass information to my startup servlet, for example
          the user and pw for our connection pool. The startup servlet instanciates
          the class Global which creates a db-pool with the user and pw getting
          from
          the startup-servlet.
          startup-servlet {
          public void init(ServletConfig config)
          Global.init("user","pw");
          The class Global looks like this:
          class Global {
          static {
          // register jdbc driver
          // store file informations
          static public init(string, string) {
          // init the connection pool with user and pw
          static public getConnection() {
          // returns connection from pool
          All our other servlets then just use the methode Global.getConnection()
          and other methods from the class Global.
          All servlets works perfect and can access the db-pool.
          When a jsp-file is called which also uses the methode
          Global.getConnection(), a new Instance of the class Global will be made.
          In order to init all values again, I would have to call the
          Global.init(user, pw) methode again.
          So my question is: Why does the jsp file causes a new instance of the
          class Global?
          Does the WL5-JSP-servlet use an other classloader then the other
          servlets??


I am seeing the problem is sp3. I can't use sp4 becuase form based
          authentication, FBA, was broken. I can only hope that FBA will be
          re-fixed in sp5.

Problem JDBC Connection using OCI Driver on Weblogic Portal on Linux

Hi Team,
I want a JDBC connection using OCI Driver in Weblogic Portal 8.1 sp4 on Linux. When I had tested using JDBC connection using Plain Java Code it is working. Also when I create the OCI Connection Weblogic Connection Pool it is working.
But My Requirement is to create the connection using Java Code in Portal Application
But When I create OCI connection in the code it is throwing NO SUITABLE DRIVER Found.
---------- Code in Plain Java Code ------------ Same code is used in Weblogic Portal Application --------------------------------
     public static void main(String[] args) throws Exception{
          Class.forName("oracle.jdbc.driver.OracleDriver");
          DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
          String url="jdbc:oracle:oci8:@TESTDB";
          Properties props = new Properties();
     props.put("user","scott");
     props.put("password","tiger");
          conn=DriverManager.getConnection(url,props);
When I am using the same code in Weblogic Portal and Deployed on Weblogic Portal Server 8.1 SP4 it is throwing following error.

Hi Vishnu
Looks like a classloader issue. BEA class loader is very tricky. Any jar added manually in classpath, will end up loading only those classes. Any imports that we have in any of those classes do not get loaded. Anyhow, coming to your point, add classes12.jar inside your portal web project Web-Inf/lib folder and see if that helps. Usually thats where we put all the JARs for 8.1 SPxx applications. If this still breaks, then remove the jar from web-inf/lib folder and add under your portal app App-Inf/lib folder. First try with app-inf/lib folder having this jar. If not then with web-inf/lib. Basically web-inf is specific to that web app only. If you have a different app having this jdbc code, then put under app-inf/lib folder. Make sure that you remove the classes12.jar that you added in classpath either in env variable or in setdomainenv.cmd file.
When weblogic uses native OCI Drivers, it refers to jars at this location: ....\beawlp814\weblogic81\server\ext\jdbc\oracle\10g or 9g. Try using one of these jars and see if that works. Most of the times I used these jars only for oracle specific native drivers.
Word of caution. Try to use Connection Pool and a DataSource created in weblogic console for your jdbc code. This Datasource can still use the Oracle drivers that you want (instead of BEA Weblogic wrapper oci drivers) located in above location. Use JNDI Lookup and get Datasource and then connection. This is more recommended approach with many advantages then using DriverManager approach..

Problem with default oci driver with database ORACLE 8.1.7

Presently our application is using weblogic 5.1 with oracle 8.1.6 database. Our
application uses OCI driver to connect OraclePool. We used weblogic/lib/solaris/oci815_8/libweblogicoci36.so
libraary to connect to dataabse.
We upgraded our Database from 8.1.6 to 8.1.7. After upgradation of database from
8.1.6 to 8.1.7. By using above shared library we are getting following error.
In the weblogic connoction pool, we specied minimum as 4 connections. When it
is creating connections while startup first connection is successfully connecting
and second onwards it is giving following error.

For Oracle 8.1.7 do we need to any other library other than oci815_8. If so can
you send those details

Looks like you are using Oracle OCI driver and not WebLogic OCI driver so
you really dont need the libweblogicoci36.so file in your
LD_LIBRARY_PATH/PATH. Also your properties below show that you are using
thin driver url and then also oci8 url, check you connection pool setting
properly and may be try getting the latest oracle drivers.
If you are trying to use weblogic jDrivers make sure your pool properties
are set right.

Using network drive with time machine. IS IT POSSIBLE?

There are lots of discussion on using network drives with time machine. I have not been able to make them work. Could somebody tell me if this is possible

Time Machine does not back up to network drives, except Time Capsules or USB drives connected to an Airport Extreme, or a drive on a Mac running Leopard.
Here's the official word: http://support.apple.com/kb/HT1733
You may find some "hacks" that might make it work, in some cases, to a degree. But use them at your own risk.
First, since this is *unsupported by Apple,* there's nowhere to go when there's trouble.
Second, you're risking a future update preventing it from working, and perhaps rendering your backups useless.
If you still think this is a good idea, do yourself a favor before you bet your backups on it: be sure it really works, at least for now:
1. Get a copy of CarbonCopyCloner or SuperDuper! or the like, and make a full bootable clone of your internal HD, on an external disk. Test it by booting from it. Then reboot from your internal HD.
2. Let TM do it's first, full, initial backup.
3. Attempt a full system restore (like you'll need when, not if, your internal HD fails), via the instructions in item 14 of the of the Frequently Asked Questions post at the top of this forum.
Again, even if it works today, tomorrow is another day . . .

[pavilion g7-2116sr] How can I use amd driver with only integrated graphic?

Radeon hd 7670m is disabled coz it's broken. Amd driver don't work. Windows use vgasave driver. How can i use amd driver with radeon hd7660g?
P.S. Sorry, my english isn't good(

Hi @Leys
I see you are stilll unsuccessful installing the drivers as you get the blue screen.
Here is a link to Computer Does not Start (Windows 7, Vista, XP) that may help.
Here is a link to Testing for Hardware Failures (Windows 7, Vista) to determine if your graphic card is defective.
If the graphic card fails, here is a link to the HP Pavilion g7 Notebook PC Maintenance and Service Guide. Please note page 9 or chapter 1 page 9 for a list of recommended replacement graphic cards.
If the graphic card passes you may wish to consider doing a restore back to a known good time or a full recovery back to factory.
Using Microsoft System Restore (Windows 7)
Performing an HP system recovery (Windows 7)
During the recovery process there is an option to backup your personal files to prevent data loss. If you have not done one yet I suggest you do one now.

MOVED: Using 4xsata drives with MSI K8N NEO2

This topic has been moved to AMD64 nVidia Based board.
Using 4xsata drives with MSI K8N NEO2

Hi , yes unfortunately it's true !
Sata ports 3/4 is the fully nforce3 native chipset integrated (uses nvidia integrated PHY).
Use only theese if overclocking .
Satallink clock will be retained at 100mhz always .
Sata ports 1/2 are bridged from the nvidia chipset to an external marvell PHY .
Theese ones can not be used with HTT ref clock beyond ~230mhz +/- a few mhz without producing data corruption .
Satalink ref clock of 100mhz will scale upwards with increased HTT .
This issue applies to all nforce3 250GB/Ultra based motherboards with more than 2 sata ports regardless which vendor/make/model.
It's the chosen hw design that is the issue and no bios ever will fix it .
If you must have 4 sata drives , do like me and install a pci SIL sata controller card for the drives used for storage .
Take Abit NF8 (nf3) as an example .It has only 2 sata ports .
Why ?
Only the true/fully chipset integrated sata ports is used .
Although the nforce3 chipset supports a sata link to an external PHY for port 3 and upwards some has chosen to not utilize it .
Nforce 4 chipset has corrected this hw design by adding more sataport by the link to external phy .
In nf4 four ports are fully/true chipset integrated , and does not suffer from this overclock barrier .

Can we use external drive with ipad air

can we use external drive with ipad air?

There are some wifi-enabled drives that allow you to stream content (music, films, tv programmes) to an iPad, but you can't directly connect one to an iPad.

I have been using my iPad with sim for weeks now, just 24 hrs ago the message I am having is no SIM card installed, I tried it with some other SIM card same same still pop up. What can I do pls

I have been using my iPad with sim for weeks now, just 24 hrs ago the message I am having is no SIM card installed, I tried it with some other SIM card same same still pop up. What can I do pls

ok, I did, and it said again congrats your iPhone is unlocked, but, when it said there was a new carrier update, I cancelled it, but, it asked me again, I cancelled again, I guess I'm scared it will lock it again if I allow the carrier update.
Oh, there it goes again, this time on the phone, arg. I hit update, I hope it doesn't freak out.
I'm glad I didn't destroy the SIM like I almost did. But, it will come out again, longer battery life with the cell portion turned off.

Using a single connection for jsp, servlets and classes

Hi! I'm building a web site that uses JSP, Servlets and some classes. I use database access in all my pages. I want to open a connection and use it for all the pages while the user is in my site, so I don't need to open a connection with every new jsp or servlet page. My software must be capable of connection with various databases, like SQLServer, Oracle, Informix, etc... so the solution must not be database (or OS or web server) dependant.
Can you help me with this? Some ideas, links, tips? I'll REALLY appreciate your help.
Regards,
Raul Medina
