Overall, I am still of the opinion that the average performance of top C compilers will beat the performance of Sun's Java virtual machine. However, eight to ten times is a ridiculous number. Remember that extraordinary claims require extraordinary evidence. You've provided no evidence at all. My own experience, by the way, is that it's difficult to do TOO awfully much better than gcc -O3. In fact, -O2 does reasonably well, and the difference between -O2 and -O3 is itself relatively small. Intel's compiler can definitely generate better code on average for Intel platforms that gcc does, but the margin is *not* going to be several hundred percent. -- www.designacourse.com The Easiest Way To Train Anyone...

I've tended to do this differently; specifically, I'd designate a directory for plugins, and usually provide a property so that directory can be changed with a -D option to the VM. That directory would contain JAR files, and there'd be a plugin description of some type in the META- INF directory of those JAR files. This has the advantage that the app can still scan for plugins at runtime, rather than someone having to maintain a global configuration files that specifies all of the plugins; and that you can keep information about a plugin bundled with that plugin itself, so that a plugin can be added or removed with as a single file. IMO (to Mike) having loose class files around is just *really* asking for trouble. JAR files are a nice way to take a set of code and bundle it all together. With loose class files, you'd have to worry about identifying which classes are plugins and which are not; which classes belong to which plugins, and so forth. -- www.designacourse.com The Easiest Way To Train Anyone...

The directory is scanned for class files and a Class.forName gets the class, if it is not assignable to my Inteface it is rejected. There is only one simple class implementation required.

I agree that variable names and well-structured code are more important to get right than formatting. However, something expressed through formatting is still expressed better than if it were written in comments.

I suspect that it has nothing to do with serialization at all and that your write call just blocks because the buffer of the PipedInputStream is full. You have to read it in a different thrad.

Best regards, Sinlee == 4 of 5 == Date: Thurs, Dec 9 2004 9:20 am From: [EMAIL PROTECTED] I should add that what you suggests make sense because the problematic serialization occurs generally on larger composite objects. Your reply had lead me to think about how I serialize very large object. upon inspection of the code, I see that I actually use ByteArrayOutputStream and ByteArrayInputStream for very large object.

Since I don't see any code (should be a separate thread) reading the pipe, I'd guess that you're filling up the pipe.

My guess is that it's a problem with the video card. There are definitely known problems with the interaction of some 1.4 versions of Java and some (especially ATI) video cards. There are also options to prevent Java 1.4 and later from using graphics acceleration, and they might help.

In particular, I'm trying to get an attribute called 'objectSID', which is of type Octet-String on the active directory. My problem is that when trying to convert the returned value to a hex representation, some of the bytes are incorrectly converted. Let me explain further: After performing a certain query on the ldap server, I read the returned objectSID attribute by calling: String value = (String) attrib.get(); ...where attrib is the attribute containing the retrieved objectSID. While debugging, I do a simple print out of the above string (using a simple System.out.println(value)), to get the following byte representation: u?uT?` C 2? I use Apache's commons-codec API to convert the above string to a Hex represenation as follows... String hex = new String( Hex.encodeHex(value.getBytes()) ); ... and when I print it out, I get: 010500000000000515000000753f75540f3f601d43170a323f040000 However, the correct hex value as stored on the active directory server when performing a certain query, should be as follows: 01050000000000051500000075b975540ff8601d43170a32e4040000 This is close, but not quite the correct value. In fact, when I try to reverse the correct hex value to the byte representation, I get: u¹uTø` C 2ä ... which is therefore the actual value that I should be getting when reading the naming attribute in the first place and casting it to a String, right? I believe the problem has to do with character encoding, but I don't know how to proceed from here. I have tried various character sets when converting 'value' to a byte array above, but to no avail.
