Strange, I cannot see anything wrong with your code. Are you sure that the compilation worked successfully and the class file exists in the directory where you are calling the java command from?

Since your main declaration looks correct, it most likely the compile was not successful.

Look in the directory where you are compiling. See if the file GraphExplore.class was created.
You will get that message if it is not being created as a result of an error. As a further experiment, try misspelling the name when you run it, you will see that it is the exact same error.

Deploy an ASP.NET application on WebLogic

Hello all,
I'm a .net developer.
I have a project that I might get into.
The thing is, the servers are WebLogic.
I don't know a lot on this subject so I wanted to know if I can deploy my asp.NET application on that server (or what I have to do for that)

Thanks for any help

I know it's an ASP.NET application question but since it's also related to Java, I thought that here is also a relevant place to ask. But I'll try there.

There is nothing Java related in your question.

WebLogic is an Oracle server for running Java apps.

There are only 10 types of people in the world, those who understand binary and those who don't.

OP's question still has nothing to do with Java programming.

True. But I don't see a better place to put it on CP.

It belongs in Q&A or Hosting & Servers, it has nothing to do with Java.

In general - no.

There are specialized instances such as writing a proxy or running a command line app but I doubt that is what you had in mind.

Error connecting Oracle on localhost: Could not get JDBC Connection ?

Hi everyone,

I am trying to connect Oracle database from my web application using Eclipse.
But I got the error:org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection;

I used below code:

Java

public static void initDB(){
		try {
			BasicDataSource ds = new BasicDataSource();
			ds.setDriverClassName("oracle.jdbc.driver.OracleDriver");
			ds.setUrl("jdbc:oracle:thin:@localhost:1521:xe");
			ds.setUsername("mybank");
			ds.setPassword("123456");
			
			jdbcTemplate  = new JdbcTemplate(ds); // throw exceptiong after this line
			isConnected = true;
			initSystemPros();
		} catch (Exception e) {
			System.err.println("Cannot connect to DataBase");
			isConnected = false;
		}
	}

I tried to use SQL Developer to create a connection using above settings and successful.

Do you know what is wrong ?

Thanks and regards,
Tai

Be sure that `xe` is your `Service Name`.

If the connection is successfull but you have this exception `SQLNestedException: Cannot create PoolableConnectionFactory (Io exception: The Network Adapter could not establish the connection) at`
"

you must have an incompatible version of JDBC, install the correct one:

There is no such code. You need to design some smileys for yourself, and write the code in the server and client that handles them.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
