The catch?
XML does not support named entities by default, you have to declare it before hand. Only < > & " and ' are predefined.

Something like:

1
2
3

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp "&#160;"> ]>
<xsl:stylesheet xmlns="http://www.w3.org/1999/XSL/Transform" version="1.0">

Got this from here…

The fix…
Instead of using named entities in the XML (I think this also affects JSON, I could be wrong since I didn’t test this is JSON) like ñ, use character references to support special character encoding.

Example:
white space =   =  
ñ = ñ = ñ

they are all the same… #160 is referenced/mapped to ” ” and #241 is referenced/mapped to ñ

So when forming your XML before returning it through an AJAX call, form the special characters via character reference.

Hope this helps you out there having this problem.

So anyone having this problem, check the following…

• What OS are you running? Vista/Win7?
• What IDE are you using?
• Was your IDE elevated to admin status?

So, check your OS, I’m using Win7. I was developing this under WinXP a few months back, and now under Win7, the folder is protected since it was under the “Program Files (x86)” folder group. (Argh!)
I closed my IDE, using IDEA IntelliJ 9.0, ran the IDE under “Administrator Level” and the problem disappeared!

So check those out first.

Now I have been working around with flash actionscript 2 for a few months now and last week I was trying to connect to google analytics using flash actionscript 2, I know there’s already Actionscript 3 but its AS2 that was required for the project After a few days of trial and error, finally got the stupid code to work, my initial code was not able to properly remove the white spaces from the returned IDs sent by Google. Weird thing is as I googled around the web, people seem to have a problem logging in and authenticating google AuthID through flash AS2 and AS3. As I understand it, there was supposed to be no way of authenticating the AuthID unless google add an option in their crossdomain.xml.

Well… seems like I was able to login and authenticate using the google account’s AuthID and retrieve my Profile list as well as used the profile data to retrieve the analytics data from my account =)

Codes are shown below on how I was able to login and authenticate the AuthID. One note, ALWAYS remove the white spaces (\r and \n) that was returned after initial login process (email & pass).

Note this is just a proof of concept and I didn’t do any clean-up,etc…
This will also work with Actionscript 3…

Any suggestions and comments are very welcome.

Update: I’d like to add that this only works on your local machine, if you upload this to a live server or website, you will need a crossdomain.xml from www.google.com to allow your site.

I was following the tutorial from Sun in creating my first JNI and calling my compiled C++ library, I was stuck in the last part where this error popped out whenever I tried to invoke

java HelloWorld

the error was…

java.lang.UnsatisfiedLinkError: no HelloWorld in java.library.path
          at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1709)
          at java.lang.Runtime.loadLibrary0(Runtime.java:823)
          at java.lang.System.loadLibrary(System.java:1030)
          at HelloWorld.<clinit>(HelloWorld.java:<line number>)
Could not find the main class: HelloWorld. Program will exit.

one way of fixing this is to include the current location of your newly compiled shared library (ex. HelloWorld.so). I’m using Ubuntu linux,so to include the current folder where your “.so” file is located, invoke…

LD_LIBRARY_PATH=`pwd`
export LD_LIBRARY_PATH

or you can also do …

LD_LIBRARY_PATH=.
export LD_LIBRARY_PATH

another way is to define the location when running the program…

java -Djava.library.path=. HelloWorld

this will instruct java to locate the native library in the current location. Now call your program again and this time it work execute your native program.

It’s possible that when you execute your program after doing the above steps, another error will come out. This happened to me and the culprit was when I compiled the cpp file. The error would look something like…

java.lang.UnsatisfiedLinkError: <library location>: <library location>: only ET_DYN and ET_EXEC can be loaded
        at java.lang.ClassLoader$NativeLibrary.load(Native Method)
        at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1778)
        at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1674)
        at java.lang.Runtime.load0(Runtime.java:770)
        at java.lang.System.load(System.java:1005)
        at HelloWorld.<clinit>(HelloWorld.java:16)

to fix this, include the “-shared” option when compiling the cpp file.

g++ -shared HelloWorld.cpp -o HelloWorld.so -I /path/to/your/java/include/folder/where/jni.h/is/located -I /path/to/your/java/include/linux/folder/

Do not include the “-c” option, this will skip the linking stage.

Stay tune

That didn’t fixed the problem.

There was something else running when windows starts up. Next target… DLLs. Amazingly, there were dlls that was out-of-placed and curiously named. Example crypt32.dll that wasn’t signed by microsoft. Removed the entry and tried to remove the dll. No luck, its being used. Next tool that was very useful was Unlocker. I ‘unlocked’ the hook for the dll and restarted. Still didn’t fix it but I was getting close. There were two more dlls I found that was very suspicious. I tried to kill one and removed, the other regenerated the dll. I try to unhook the other dll, the whole pc restarts. Smart bugger. Thank goodness for safe mode. Restarted in safe mode and use unlocker again to unhook the dll. Removed one of the dll and its entry in the registry. Good… it didn’t restart… just a countdown for a system shutdown.. freaking dll.

The system restarted and good news is the dll that forced the shutdown wasn’t regenerated. Last dll was a bit simpler. Used unlocker to unhook the dll, deleting was not successful, though unlocker had a feature to delete the dll after a restart. Selected the option and waited. Thankfully, the whole ordeal ended there. All three dlls didn’t regenerate after that.

Note to PC users who watch videos from torrent ( Heroes, Prison break…). If it asks you to download a player to run the video you downloaded.. DON’T!!

FLUSH LOGS;

Bring in a fresh copy of the database from the master-server and update the slave-server database. THIS IS IMPORTANT! Since if you don’t update the slave database, you will not have the data from the time you were disconnected until you reset the relay logs. So UPDATE YOUR SLAVE WITH THE LATEST DATABASE FROM THE MASTER!

Now when the logs are flushed,all the relay-bin logs will be deleted when the slave is started again. Usually, this fixes the problem, but when you start the slave and the failed relay log error is still there, now you have to do some more desperate measures… reset the slave. This is what I had to do to fully restore my MySQL slave server. Reseting the slaves restores all the settings to default… password, username, relay-log, port, table to replicate, etc… So better to have a copy of your settings first before actually do a slave reset. When your ready to rest the slave, do the command…

RESET SLAVE;

after which you should restore all your setting with a command something like…

CHANGE MASTER TO MASTER_HOST=.....

now start your server with…

SLAVE START;

check your slave server with…

SHOW SLAVE STATUS\G

look for …

Slave_IO_Running: Yes
Slave_SQL_Running: Yes

both should be YES, if not, check your syslog if there are other errors encountered. I’ll leave this until here since this is what I encountered and I was able to fix it.
