proxml: path to documentURL / loadFrom()
Sep 8^th, 2005, 6:33pm

hi there,

i have an ugly problem with the fileimport/absolutePath in an applet that bases on proxml:

proxml works fine in the environment by loading the xmlfile with the function:
xxx.loadFrom(folder + "/thefile.xml");

BUT: after exporting as applet, the xml file is not found and the applet won't start.

if i include 'folder' in the error output of the catchstatement, it will print 'null' in the javaconsole of the browser

PLUS: if i try to get the absolute path > getAbsolutePath() etc. of thefile.xml, the applet wont't get the permission to read dir.

btw.: relativepath (without 'folder')to the xml file does work in the environment; not as applet.

does anyone has an idea how to
either assign the relative path from thefile.xml to the function loadFrom() or setDocumentUrl()
or read thefile.xml as String[] lines; etc and assign that completely to proxml ?

(or does this problem simply base on wrong placement of the xml file location in the appletfolder)

the last 2 days i made desperate efforts to fix that problem. if anybody has some helpfull hints...

(hm... liked proxml better, but at least i got it to work as applet.) cu:MissYen

I tried to get an applet run but it was not possible. I will try to fix this as soon as possible and post the progress here. tex

hi tex,
thanks for your reply (and for your great piece work with proxml at all).
while my effords to get proxml running i took a look at your library, but i didn't find a public function to assign something like an input stream to. (probably my fault.)

[ perhabs there should be a public funktion for something like private Reader openXMLFile(String file)?
... of course, it's your code and you'll know it best

]

well, basically, if you try to parse the path via any java.io function (to assign that string to 'folder') the applet will throw a security error. so either you have to sign the applet (yuk!) or you have to find a way to read data or file from relative path from inside your folder/server. so far ... looking forward for the next proxml version. good luck with fixing.

I tried to make an Applet just out of the included Example and it didn't work. Any hint would be great looking forward to put proXML stuff online.

If it is still not working give me your example code.

hi there,
short update ref. xml parsing >without php redirection< using nanoxml

the applet:

the sourcecode:
http://lehre.hki.uni-koeln.de/~kurz/ps05/Seminararbeiten/hoehne/dateien/quelltext.txt
see >
// XML PARSEN UND DATEN DEN KLASSEN/INSTANZEN ZUWEISEN
void dateiLaden() and void parseXml() ~ in the middle of sourcecode

for anyone who's interested and does understand german > the paper:

hope it might help.

Hi This would work with proXML now, too and without the need of an InputReader, you only need php redirection for XML files from external urls for example flickr. But this is caused by the java applets security restrictions. The example I gave is working without php.

http://texone.org/proxmlapplet/

Please check the new version It loads xml files also in the applet.

vade YaBB Newbies Offline Posts: 38	Re: proxml: path to documentURL / loadFrom() Reply #9 - Nov 25^th, 2005, 6:59am proxml seems broken with 0.95, due to renaming the folder variable to the path variable. I attempted changing the pApplet.folder strings to pApplet.path in XLMInOut.java, but to no avail. Any chance for an update anytime soon? Thanks,

Duh, I forgot to recompile the .class files. I was getting some errors with 0.95 when compiling XMLInOut.java, line 245 :

Code:


vade$ javac -d . -classpath /Applications/Programming/processing-0095/lib/core.jar *.java
XMLInOut.java:245: cannot resolve symbol
symbol  : method toURI ()
location: class java.net.URL
                                file = new File(pApplet.getClass().getResource("data/" + filename).toURI());
                                                                ^
1 error

I dont know java well enough to fix it, so I just copied another line, and probably broke something. But, i was able to load in files just fine. Thanks, look forward to a new point release!

Also, since this is useful for reading in RSS and ATOM feeds, is it possible to remove the needed <?xml /> firsttag, and possibly check for <feed /> or something like such? (some feeds validate without the <?xml /> tag initially.

Thanks!

Hi there, I just downloaded the new version of proXML and was trying to run the
Example application, but I always get:

java.lang.NoSuchFieldError: path

In both p91 and p97

When I tried my proccessing application I get the following:
apple.awt.EventQueueExceptionHandler Caught Throwable : java.lang.NoSuchFieldError: path

is this cause I am on osX ?

Thanks,
Elmar

First it was folder in 0.96 it was path and now it is sketchpath. I will upload the update as soon as possible definetly this week. For the moment you could use version 0.96
