Using java code to connect to Docbase(Documentum)

After a long pause I am writing a technical article on Connecting Documentum Docbase with a Java Code.

Would not speak much and start with the code directly.But here I will assume that you know the basics of Documentum, have the DFC installed in your windows system in c:\Program Files\Documentum folder. In case you want to know the basics or trying to figure out about the DFC classes or any dumb question you have in your mind just shoot me a mail(escortnotice@gmail.com) or raise a question in this post.I will definitely try to help.

IDE used – Eclipse

Additiona Jars needed:- Give the path of all the jars in (C:\Program Files\Documentum\Shared) folder.

Code:- It will  connect to the docbase and return a message on successful connection.

import com.documentum.com.IDfClientX;
import com.documentum.fc.client.DfClient;
import com.documentum.fc.client.IDfClient;
import com.documentum.fc.client.IDfCollection;
import com.documentum.fc.client.IDfQuery;
import com.documentum.fc.client.IDfSession;
import com.documentum.fc.common.DfException;
import com.documentum.fc.common.DfLoginInfo;
import com.documentum.fc.common.IDfLoginInfo;
public class DocbaseConnect {

IDfSession session;
IDfLoginInfo login;
IDfClient client;
IDfClientX clientx;
private static final String DOCBASE=”MYDOCS”;
private static final String UID=”User123″;
private static final String PASSWORD=”Password123″;
IDfQuery query;
IDfCollection col;

public void ConnectDocbase()
{
try {

/* will help to see the registered path variables with windows  in case of error “java.io.FileNotFoundException: Cannot    locate file – dfc.properties”*/

System.out.println(“Classpath:”+System.getProperty (“java.class.path”));

client=DfClient.getLocalClient();
login=new DfLoginInfo();
login.setUser(UID);
login.setPassword(PASSWORD);
session=client.getSharedSession(DOCBASE, login, DOCBASE+UID);
if (session.isConnected())
System.out.println(“Connected to Docbase”);
} catch (DfException e) {
e.printStackTrace();
}
}
}

Now most of you might get the below error:-

“Exception in thread “main” java.lang.Error: Failed to load preferences: java.io.FileNotFoundException: Cannot locate file – dfc.properties”

If this is the case then that means your environment variable C:\Documentum\config is not set which has the dfc.properties. If it is set and still you get the error then just check out the Console message that you have printed for the environment variables registered.I am sure you won’t see it. Below is the step you must do.

>  Right click on Project you have created for this

> Project->Properties->Java Build Path-> Select the Libraries tab->Click on Add Class Folder from right panel->Create New Folder->Advanced->Link to the folder in the system->browse to the path  c:\Documentum\Config.

For me the Documentum Folder is in C:\. You need to identify for you what is it and give that path.

Then run the file and I hope it will connect to your docbase.

Try Coding and Try it till it runs successfully……….
