How to connect mysql database using xml

welcome to all,
here my doubt is how to connect mysql database using xml file, how to integrate xml file and jsp file and how to access data from dabase using jsp file. can any one help me
regards

Short answer: you wouldn't do any of those things. The first two are meaningless and the third is a bad practice. I have no idea what those ideas were supposed to achieve so I have no idea what tutorials I should suggest to you.

How to connect one database in two threads?

Dear All,
If anyone can tell me how to connect one database concurrently?
I tried the following idea:
1.create a Hashtable to keep database objects(those databases have been opened)
2.Before openning(connecting) a database:first step is to check the hashtable.
If the the database object is in the hashtable, this object will be returned.
If the datatbase object is not in the hastable, open the database and store this opened database object into the hashtable.
I failed the test of this implementation. My test is:Create two threads (extend java Thread class).In each of these two threads, try to open the same database.Just like the following:
MyThread thread1 = new MyThread();
MyThread thread2 = new MyThread();
thread1.start();
thread2.start();
I guessed the database object in the hashtable would be returned in the second thread.Unfortunatly, I only got an exception which meant the database couldn't be opened twice.It looks like the second thread happened before the opened database object stored into the hashtable.
I cannot figure out if my design is wrong or my test application is wrong.
I really appriatiate your attentions!!!
Lu

um not sure i follow exactly but in your code add the word synchronise to it and this means only 1 tread can access it at any 1 time.
So your could have a class which is a singleton so it only opens the dbase once and then all other access share your connection.
so
public class foo{
foo INSTANCE = new foo();
private foo(){} //private constructor
then all your methods use foo's internal dbase connection. Am i making sense

How to connect sybase database in JDeveloper 11g using JConnect

Hi
How to connect sybase database in JDeveloper 11g using JConnect? Please help.

User,
It would help if you explained Sybase Jconnect instead of leaving us to google.
At any rate, it appears you need to create a library definition in JDeveloper, add the appropriate JConnect JAR files to the library's classpath, and then add the library to your project.

How to connect oracle database from tuxedo

Hi,
How to connect oracle database from tuxedo.
If any one can help me.
Regards,

it depends on configuration your going to choose, there are two ways--
- Using X/Open standards, for this
you have to make an entry of Resource manager in $TUXDIR/udataobj/RM file.
Then in UBBConfig file in GROUPS section u have to set Openinfo.
It also depend on which database you are going to use.
In your service now you need to call tpopen() API from tpsvrinit() function.
- Other possibility is, take an implicit connection using Pro*C or Pro*Cobol whatever platform you are using.

How to connect labviewv database toolkit to SQL CE server

Dear sir,
i am using labview 8.2.1 and Database Connectivity 8.2.i need same simple concept of how to connect LV database toolkit to SQL CE Server.

When opening the database connection, you will need to provide either a connection string, or a path to a UDL (which will contain a conenction string). The easiest way to get a connection string is to go to (no I am not kidding) www.ConnectionStrings.com. Once there you enter the type of DBMS you are trying to connect to, and the system will list connection strings that you can use based on the drivers that you're using.
How much experience do you have with LV and/or databases?
Mike...
PS: you might also want to check out a series I did a bit ago on database connectivity in my blog. See the link in my signature...
