myException is not autoloaded

[nosilume]

Hi all!
I have a problem with a custom exception class, myException, which is a wrapper for sfException.
<span name="php"><code><span style="color: #000000">
<span style="color: #0000BB"><?php </span><span style="color: #007700">class </span><span style="color: #0000BB">myException </span><span style="color: #007700">extends </span><span style="color: #0000BB">sfException </span><span style="color: #007700">{} </span><span style="color: #0000BB">?></span>
</span>
</code></span>
The file is called "myException.php" and is inside of lib/
If I use <span name="php"><code><span style="color: #000000">
<span style="color: #0000BB"><?php </span><span style="color: #007700">throw new </span><span style="color: #0000BB">myException</span><span style="color: #007700">(</span><span style="color: #DD0000">"foobar"</span><span style="color: #007700">) </span><span style="color: #0000BB">?></span>
</span>
</code></span>
, I get an error Fatal error: Class 'myException' not found…. But if I use
<span name="php"><code><span style="color: #000000">
<span style="color: #0000BB"><?php </span><span style="color: #007700">throw new </span><span style="color: #0000BB">sfException</span><span style="color: #007700">(</span><span style="color: #DD0000">"foobar"</span><span style="color: #007700">) </span><span style="color: #0000BB">?></span>
</span>
</code></span> instead, the code is working. I'm using 1.1-DEV. I hope someone can help me!

Thank you very much,
Christoph

Did you clear the Symfony cache before you tried to run?

This is always necessary after changes in config or adding/removing extra classes.

[nosilume]

I cleared it several times, although i thought, this is not neccassery in 1.1.

In which lib/ directories are the two files: the one with the myException class and the one that calls it?

[nosilume]

myException.php is in $project/lib and the exception is thrown in an action file.

If I am correct, class files should be named xxxx.class.php. Does renaming help?
