serializing an object to the same source package

shyameni · #1 (**permalink**) 11-06-2009, 06:53 PM

I want to store an object to an XML file in the same source package of the project. Is this possible to do without giving the absolute path to the file so that it will work in any machine??

Plz help me with this.

regards,
shyameni

The source packages of your project are not used when running the program. You'll most likely just distribute a .jar file for other computers.

hey thanks,
but i want to write and read from that xml file during the execution of the jar file. When i insert it in the project folder it didn't work. Thatz why i thought putting it in the source package will work and accessible through the jar file.

Or is there any other way to access a database which can be put inside the jar file with write and read is enabled.

Read about Derby if you want to embed a database.

Do you mean that the database is read only? What happens when you run an insert or an update?

thanks for concerns,

i think the problem was that the driver of the database was clientDriver not embeddedDriver, there was no option to change it to EmbeddedDriver.

Can u plz tell me where can i change that option.

I installed derby by following a tutorial in the web, i think i did it correctly.

Follow the tutorials that come with derby itself. They explain both options.
You should be able to update in both options anyway.

P.S You didn't answer my question above?

sorry i dont dt code with me anymore, dtz why i couldnt answer ur question,
i thought itz all useless and i deleted the whole project.

Anyway u are saying that it should work both ways i mean with embeddedDriver and the clientDriver even after creating the jar file, then im happy bcos i can strive for something worthy and i hvnt got much time.

thanks
