I'm working on a database application in Borland JBuilder 2006 on Linux
Fedora Core 4 platform. I choose JDataStore as database, and
JasperReports for reporting part.
My connection code looks like this >
String app_path = "/home/brunetdj/my/source/jbuilder/info2006/";
String db_path = app_path + "data/podaci.jds";
database.setConnection(new ConnectionDescriptor("jdbc:borland:dslocal:"
+ db_path,"SYSDBA", "masterkey", false,
"com.borland.datastore.jdbc.DataStoreDriver"));
So, my problem is in variables app_path and db_path,
which is useless in MS Windows platform, and program stop working.
Application and database path are not the same semantics in both OS.
And where is that transparency of Java in that two small variables ?
I've searched Internet (Google,Sun forums, e.t.c.), but without results.
There is some partial solutions, like >
- to put database in class of project, and get path with getResorce()
method. That is unpractical because of huge database size
- to put all resources in root project folder, which also make chaos
with files
- to use system variable user.dir, which retrieve root user folder on
Linux, and different in MS Windows
Is there a way to use some methods to get app.path or project.path ?
Absolute adresses is untransparent on diferent operating systems.
Please, help, if anybody can. |

I would follow John's suggestion fiurst. An alternative is to make sure that |
your paths are not linux/mac/unix specific.
For instance something like /data/pdaci.jsd would work on Windows and Unix,
provided you created a /data (Unix and Mac) or C:\data (Windows)directory
and put the podaci.jds file in that new directory.
Another option is to put the database in the classpath directory of your
database connection class. Then
Url url=this.getClass().getResource("podaci.jds"); |

I would suggest placing those values in a property file in the
executable directory..
Then you can make the appropriate changes based on the OS..
