IConnection-get|ConnectionEx(spec) throwing null pointer exception

[Former Member]

Hi,

I closed a thread recenly and here is another one.

I have to fetch some data from MDM and bring it to my Web Dynpro application.

		IConnectionSpec spec = connectionFactory.getConnectionSpec();

		spec.setPropertyValue("UserName", "User");
		spec.setPropertyValue("Password", "User");
		spec.setPropertyValue("Server", "<IP ADDress>");
		spec.setPropertyValue("Port", "XXXX");
		spec.setPropertyValue("RepositoryLanguage", "English[US]");
	
		try{
			IConnection connection = connectionFactory.getConnectionEx(spec);
		}
		catch(ConnectionFailedException cfe){
		}
		catch(ConnectorException ce){
		}
		catch(Exception e){
			throw new Exception(e.toString());
		}

I am getting Null Pointer exception..

Does it mean that properties i am hardcoding are wrong?

Kindly let me know what could possibly be wrong here...

Hi,

In one of these threads, i came across a statement that "I checked from portal and connection tests to MDM server passed". How can i check this?

I have a similar scenario, and have already added MDM4j etc to the portal server, but do not know how to confirm the connectivity, this can be useful for me...

Any pointers?

Hi,

I guess on IConnectionSpec. Check with notnull, so that you can findout where exactly you have the error.

Hi Sridhar,

I checked it before only and spec is not null...

Errir is coming in IConnection and when i pass spec as a parameter....

But dont know what exactly is the cause...

hi,

You can make use the below code. It is running for me.

public static IConnection getConnection()throws Exception {

Context ctx = null;

String username = "";

String password = "";

String server = "";

String port = "";

String language = "";

try {

ctx = new InitialContext();

} catch (NamingException nex) {

throw new NamingException(nex.toString());

}

IConnectionFactory connectionFactory = null;

try {

connectionFactory =

(IConnectionFactory) ctx.lookup(

Messages.getString("MDM_FACTORY"));

} catch (NamingException nex) {

throw new NamingException(nex.toString());

}

IConnectionSpec spec = null;

try {

spec = connectionFactory.getConnectionSpec();

} catch (ConnectorException cex) {

throw new ConnectorException(cex.toString());

}

spec.setPropertyValue("UserName", username);

spec.setPropertyValue("Password", password);

spec.setPropertyValue("Server", server);

spec.setPropertyValue("Port", port);

IConnection connection = null;

try {

connection = connectionFactory.getConnectionEx(spec);

} catch (NullPointerException npex) {

throw new NullPointerException("Could not able to make connection to server :" + server + " port :" + port);

} catch (ConnectionFailedException cfex) {

throw new ConnectionFailedException(cfex.toString());

} catch (ConnectorException cex) {

throw new ConnectorException(cex.toString());

}

return connection;

}

Similar code is being used by me.. but its throwing a null pointer... seems that one of the values is improper... is my assumption rite... ?
