loading Strings from URL

Hi,
please try this for example:
1. write a silly little sketch with a loadStrings() Function which is loading a String from an URL.
2. please include now some external classes to the project and you will see after you created a code-folder (with or without any files into it) the loadString() fails with an error like this:
problem loading strings from http://www.xyz.de/myscript
java.net.ConnectException: Connection timed out: connect at java.net.PlainSocketImpl.socketConnect(Native Method)
at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:305)
at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:171)
at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:15
First I thought it was only a sonia-problem (which i want to include) but this happens also if there is an empty code-folder or a code-folder with other code into it...
looking forward,
hannes

hm, i just tried it and couldn't get it to replicate. i used:
Code:String stuff[] = loadStrings("http://processing.org/download/bugs.txt");
for (int i = 0; i < stuff.length; i++) {
println(stuff[i]);
} |
|
and it was ok with/without a code folder and with/without stuff actually in the code folder (using rev 69, and it appeared to be the same on 6 .
any ideas on what else might be triggering it (i don't doubt there's a bug, i just need to figure out how to replicate)

Hi ben,
I just copied your example above and without code-folder it works well - but if I create a code-folder it doesn't run.
I'm using V-0069 Alpha on WinXP
bye,

Hi ben,
I'm already using the standard version.
I just downloaded the expert-version to see if there is a difference. ...but NO, there is also the same output. Only without 'code' folder it runs ...
Til now i'm not a real Java geek so please tell me if there is an alternative for using the loadStrings() function. Without loading Data from an URL (i need also a code-folder) i can't go on with my little sketch idea ... 
looking forward,
hannes

see if this works, doing it by hand:
try {
URL url = new URL("http://processing.org/download/bugs.txt");
InputStream stream = url.openStream();
String lines[] = loadStrings(stream);
} catch (IOException e) {
e.printStackTrace();
}
if not, here's the code to loadStrings, which might help too:
Code: static public String[] loadStrings(InputStream input) {
try {
BufferedReader reader =
new BufferedReader(new InputStreamReader(input));
String lines[] = new String[100];
int lineCount = 0;
String line = null;
while ((line = reader.readLine()) != null) {
if (lineCount == lines.length) {
String temp[] = new String[lineCount << 1];
System.arraycopy(lines, 0, temp, 0, lineCount);
lines = temp;
}
lines[lineCount++] = line;
}
reader.close();
if (lineCount == lines.length) {
return lines;
}
// resize array to appropraite amount for these lines
String output[] = new String[lineCount];
System.arraycopy(lines, 0, output, 0, lineCount);
return output;
} catch (IOException e) {
e.printStackTrace();
}
return null;
}

Hi ben,
first of all many thanks for your help!
It is funny, i tried your 'by hand' example and it is the same. With code-folder there comes now this exception:
java.net.ConnectException: Connection timed out: connect
at java.net.PlainSocketImpl.socketConnect(Native Method)
at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:305)
at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:171)
at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:15
at java.net.Socket.connect(Socket.java:426)
Now i start trying your second example ...
bye,
hannes

Oh, it seems for me that if i use a code folder i cannot get Data from any URL. I tried your second example and it runs well, but with a code-folder it throws out the same 'timeout'-exception...

do you have virus scanning/prevention software enabled, specifically norton antivirus?
i wonder if we're running into that sort of bug here..

Hey, you are so good ...
this question solves it all. I'm using the freeware version of the
outpost-firewall from agnitum, and after switching it off
i am able to load any URL-Data with a code-folder into my project...
I think there is a bug into the outpost software, or
does Java uses with / without code-folder a different security-level?
But why does outpost not ask me for enabling such kind of traffic?
many thanks for your help!

It is a little bit strange with this firewall:
if I set the JAVAW.EXE as an 'ever trusted' application then i cannot loadStrings (+code-folder)
but if i remove this entry so outpost asks me at every start of JAVAW.EXE and if i click on 'trust once' - it works ...
I think it's time to get a new firewall ...

Hey ben,
now i've got a different firewall and i found something interesting:
if i use the loadString() without code folder the firewall asks me to allow '\java\bin\javaw.exe'
and if there is a code folder it asks for '\java\bin\java.exe'
OK, now it works fine! And we know the difference...
best regards,
hannes
