I have this function to see a file, but give me an error saying: "Access denied". Even in my 6230i emulator give me the same error. I have the file that want to open on [mypath]:\Nokia_S40_DP20_SDK_6230i\bin\Storage\6230100\C\, but nothing happens, only the error.


What I have to do?

String strPath = "file:///C:/";
FileConnection fc = (FileConnection)Connector.open(strPath +fileName, Connector.READ_WRITE);

There's your problem.
J2ME can't write to C:/ sometimes

[decisor]

But I only want to read some file at some location defined.

Don't forget that I'm testing in emulator of 6230i.


What I have to do more?!?!?!?!?!?


Thanks

[rexwal]

Test it on your actual phone for starters.

In my experience , I got the same error working with a 6680. It was fine once I used E:\ (SD CARD) instead of C:\ (Phone Memory)

I may be wrong - but that's what happened to me

[decisor]

Well...

In emulator using E:/ the error ocurrs too.

In a real 6230i it's a kind of impossible, because I do not have it. Only have 6230 that not support Fileconnection API.



If anyone can help me, I apreciate.

thanks

I think the file name you are using is the problem (you should not try to access hardcoded files on your development computer anyway). There are a set of System Property strings, which get you the directories to certain files (see http://www.forum.nokia.com/info/sw.n..._2_en.zip.html)

Also check this File Connection document which lists these strings(http://www.forum.nokia.com/info/sw.n..._v1_1.zip.html)

So hartti...

1 - You're saying that I can't try my read file application on 6230i emulator?!?!?!?

2- I've already try whith DefaultColorPhone from J2ME Wireless Toolkit 2.2 and worked. Why???


If first question is correct I'm screwed because I do not have the real phone. How can I try this out!?!?!?!?!?



Thanks guys for the help

[hartti]

I think I misunderstood a little what files you are trying to access. My bad.

1. you can use FileConnection API on emulator.
2. Not all directories are available for midlets on phones/emulators. The available directories vary.

The emulator emulates the phone as closely as possible. If you want to read files in your midlet, you should query the correct and available paths from the system both on emulator and on a real device. Those are listed on the documents I pointed out before.

BTW. What is the complete file name of the file you are trying to access? (Meaning what is the file name you passing to the open() method?)

[nissimzo]

I have the same problem and no body answer here in Nokia Forums.....

[traud]

nissimzo, do you really need JSR-75 as you use fixed paths? If you want to read a static file, you can include it within your JAR. If you want to save values for later use, you should check RecordStore API. Did that help?
