Q:

Access personal geodatabase using Java

Following example through ESRI is to access the features of file geodatabase (GDB), I would like to know that is there a similar way to do this with personal geodatabase (MDB) using Java.
I am quite new to ArcObjects so if anybody could point me to right direction.

A:

You can use the AccessWorkspaceFactory instead. There are (at least) 3 ways to connect to a personal geodatabase. The simplest is probably the IWorkspaceFactory.OpenFromFile method, e.g.:
//For example, pathToFile= "C:\\myData\\mypGDB.mdb".
static IWorkspace openFromFile_pGDB_Workspace(String pathToFile)throws Exception{
    IWorkspaceFactory workspaceFactory = new AccessWorkspaceFactory();
    return workspaceFactory.openFromFile(pathToFile, 0);
}

See How to connect to a geodatabase in the conceptual help for more information.
You might also look at the various IGPUtilities helper methods if you want to deal with opening workspaces, feature classes, tables, etc. in a more generic way.
