| How do I create a Connection Profile [message #53454] |

I'm trying to use DTP programmatically, but all the documentation I've
found just addresses how an administrative user sets up connections
through the eclipse UI. Can someone tell me where I might find something
that explains how to use the API. I'm not smart enough to figure out how
to use a barely-documented API of this complexity, but I'm sure I could
figure it out if I saw an example or an explanation of some sort.
Actually I think I just need to know how to create a connection profile.
I have code that creates a driver instance, and I know how to create a
connection if I hand it a connection profile; but I can't figure out how
to create a profile, presumably using the driver instance I created.
I execute the following code and get a NullPointerException where
indicated, which I take to indicate that I need to create a profile first.
ProfileManager pfm = ProfileManager.getInstance();
if (pfm == null){
System.err.println("No ProfileManager");
}
else{
IConnectionProfile[] profiles = pfm.getProfiles(); //NPE occurs here
for(IConnectionProfile profile : profiles){
System.out.println("Profile name: " + profile.getName());
System.out.println("Profile ID: " + profile.getInstanceID());
}
}
And here's how I create the driver instance:
mgr.createNewDriverInstance(templateStringID, templateName,
pathToConnectorJarFile);

Fitz,
Thanks for your response. I'm pursuing a different implementation vector
based on some guidance I just received from my tech lead. He wants me to
define the connection profile manually rather than try to retrieve one
declared in Plugin.XML. I have some code that does that, which I'll paste
below.
I'm able to verify that the properties are set properly on the connection
profile, but when I try to create a connection on the profile, I get an
NPE thrown in
org.eclipse.datatools.connectivity.internal.ConnectionProfil e. I looked at
the source code where the NPE is thrown, and it seems to be that I don't
have a connection factory set on it. I wasn't sure what value to pass for
the connection factory parameter, so that's probably where my problem is.
My code is below. I'm also registering a driver when the workbench starts
up. The code that does that is below.
DriverManager mgr = DriverManager.getInstance()
mgr.createNewDriverInstance( "org.eclipse.datatools.enablement.mysql.5_1.driverTemplate",
"MySQL JDBC (Bundled)", jarFileURL.getPath());
Here's the code where I try to create the profile and connect through it.
String driverID =
"org.eclipse.datatools.enablement.mysql.5_1.driverTemplate";
String userName = userName;
String password = password;
Properties props = new Properties();
props.setProperty(ConnectionProfileConstants.PROP_DRIVER_DEF INITION_ID,
driverID);
props.setProperty(ConnectionProfileConstants.PROP_PWD, password);
props.setProperty(ConnectionProfileConstants.PROP_UID, userName);
try {
pfm.createProfile("MySQL", "MySQL JDBC Profile",
"org.eclipse.datatools.enablement.mysql.5_1.driverTemplate", props);
} catch (ConnectionProfileException e1) {
e1.printStackTrace();
}
IConnectionProfile profile = pfm.getProfileByName("MySQL");
if (profile.arePropertiesComplete()){
System.err.println("Properties are complete");
} else {
System.err.println("Properties are NOT complete");
}
if(profile.getConnectionState() != IConnectionProfile.CONNECTED_STATE){
profile.connect();
}
connection = profile.createConnection("java.sql.Connection");
//NPE thrown for statement above. See stack trace below
rawConn = (Connection)connection.getRawConnection();
Stack Trace:
Note: I simplified the code above, since I actually call a separate class
(SomeDatabase) where createConnection() is invoked. SomeDatabase.java line
25 in the stack trace corresponds to the line above where I indicated the
NPE was thrown.

I've gotten further along on this, but I'm still stuck.
I loaded into my target environment the DTP plug-in which provides a MySQL
connectionProfile
(org.eclipse.datatools.enablement.mysql_1.0.2.v200810160130. jar), and all
it's dependencies. I see that in the plug-in's Plugin.XML it defines a
connection profile with cateory =
"org.eclipse.datatools.connectivity.db.category" and name = "MySQL".
But when I query the profile manager for the profile by name or by
category, an NPE is thrown. Below is the code I'm executing.
ProfileManager pfm = ProfileManager.getInstance();
if (pfm == null){
System.err.println("No ProfileManager");
}
else{
IConnectionProfile profileByName =
pfm.getProfileByName("MySQL"); // NPE thrown here
System.out.println("Profile (by name) name: " +
profileByName.getName());
System.out.println("Profile (by name) ID: " +
profileByName.getInstanceID());
}
alternatively, if I execute the following code to get the profiles by
category I also see an NPE thrown
IConnectionProfile[] profiles = pfm.getProfilesByCategory(
"org.eclipse.datatools.connectivity.db.category");// NPE thrown here
for(IConnectionProfile catProfile : profiles){
System.out.println("Profile (by Cat) name: " + catProfile.getName());
System.out.println("Profile (by Cat) ID: " +
catProfile.getInstanceID());

Hey Mark...
You're definitely along the right path.
When you talk about using the API... What are you including for dependencies
in the plug-in that's calling the API?
And what's the NPE that you're getting? That'll help me better diagnose
what's going on.
