This is perhaps your intention: for (Field f : ByteCode.class.getFields()) { Annotation[] annotations = f.getAnnotations(); System.out.println(annotations.length); BCComment comment = f.getAnnotation(BCComment.class); System.out.println(comment); } Also, take a look at java.lang.annotation.Target to restrict the constructs that a particular annotation can appear on. -- Tony Morris http://xdweb.net/~dibblego/ ============================================================================== TOPIC: Socket: Input/OutputStream http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/54e7f133683aa17d ============================================================================== == 1 of 1 == Date: Wed, Dec 22 2004 11:03 pm From: "puretec" I have the following problem: a java application (client) should communicate with a sever, where the communication objects are as follows: public class Comm_1 { long lSync; long lLength; CData_1 oData1; } .... public class Comm_1 { long lSync; long lLength; // length [byte] of the object CData_n oDatan; } 1) How can I determine the length of an object in order to assign that value to o.lLength (I know how to do this by hand); 2) Is the ObjectOutputStream ( linked to the socket.getOutputStream() ) the stream which I should use for sending the objects? sincerely thomas ============================================================================== TOPIC: Socket Input-/Outputstream http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/ce6e806374050fab ============================================================================== == 1 of 3 == Date: Wed, Dec 22 2004 11:09 pm From: "Thomas" I have the following problem: a java application (client) should communicate with a sever, where the communication objects are as follows: public class Comm_1 { long lSync; long lLength; CData_1 oData1; } .... public class Comm_1 { long lSync; long lLength; // length [byte] of the object CData_n oDatan; } 1) How can I determine the length of an object in order to assign that value to o.lLength (I know how to do this by hand); 2) Is the ObjectOutputStream ( linked to the socket.getOutputStream() ) the stream which I should use for sending the objects? sincerely thomas == 2 of 3 == Date: Wed, Dec 22 2004 11:26 pm From: ByteCoder Thomas wrote: > I have the following problem: > > > a java application (client) should communicate with a sever, where the > > communication objects are as follows: > > > public class Comm_1 > > { > > long lSync; > > long lLength; > > CData_1 oData1; > > } > > > .... > > > public class Comm_1 > > { > > long lSync; > > long lLength; // length [byte] of the object > > CData_n oDatan; > > } > > > 1) How can I determine the length of an object in order to assign that value > > to o.lLength (I know how to do this by hand); Object.length, Object.get...()? Could be anything. A proper IDE has code completion.

It seems like this is an IE bug(s), but I would like to fix and haven't been able to. I'm using a struts/Tomcat-based app. I have Windows XP Professional with IE 6.x with XP Service Pack 2 installed. I'm testing and getting this error against both a localhost-based app and the same app deployed remotely. Any clues? Neither Firefox nor Opera exhibit this behavior. Any ideas? Wish I could just forget about IE, but no such luck. It's not just my machine - it's all developers at my company. I'll try to reproduce from outside of work with XP Home, but not hopeful. I've tried using both 'localhost' and '127.0.0.1'. Is there anything I haven't tried yet? I know IE sucks, but a non-functioning Back button? C'mon. And I feel the error has to have something to do with my app/struts/expires-type headers/etc - something. I actually haven't been able to verify if my app/Tomcat is sending out 'expires' and 'cache' headers of different types - I don't think so, based on the code, but at least my logon page is throwing out the following headers: Pragma: No-cache Cache-Control: no-cache Expires: Thu, 01 Jan 1970 00:00:00 GMT I think these are from Tomcat, but not sure why they're being issues, and not sure if they're the cause of my problems. == 2 of 2 == Date: Wed, Dec 22 2004 2:28 pm From: "Robert kebernet Cooper" Start by going into your IE options and turning off "Friendly Error Messages". ============================================================================== TOPIC: converting an existing Swing application to client server http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/31d2080f8f3e59a4 ============================================================================== == 1 of 3 == Date: Wed, Dec 22 2004 3:43 pm From: [EMAIL PROTECTED] Greetings, I have a Swing application that manages local devices using SNMP, and I'm looking for a simple way to convert it to run as client server. my dream is to find something that will wrap the current application, allow it to run locally and the GUI will work from a remote site.

It brings us to the basic problem that when you shift the application from the development machine to a machine with a different RE, fonts, screen size, PLAF, the UI breaks. If you use a D'n'D GUI designer (using PutItHere layouts) you effectively lose the X-plat GUI in any case. > "It would be much easier in .NET to display/edit common MS > document formats such as .doc, .xls, to get the 'OS Component', > and actively control it." > > I doubt it.

However when I try to create an instance of it, it doesnt work. Instead the tree just contains the default "colors, sports, foods" nodes. The class takes as an input a DOM and should process this DOM into the JTree. I kinda know some parts work, like addChildNodes class, because i did a system output and it outputted all the nodes in the xml file i inputed (which was converted to a dom first). Could someone please help me? The dom processing is done with JDOM.

I've read all of the these and more but if you only want one book then go with the one most readable to you. For general JSP books look at:- 1. "Web Development with Java Server Pages" 2nd edition Duane K. Fields, Mark A. Kolb Not always easy to read but a thorough and useful book. Only JSP 1.2 but add JSTL knowledge and you'll know JSP 2. 2. "Servlets and JSP: The J2EE Web Tier" Jayson Falkner, Kevin R Jones Easier to read than most, not so dry and reference-ish, a very good book. 3. The O'Reilly's JSP book. 3rd edition Hans Bergsten. More reference-ish but good. 4. Marty Hall's books:- "Core Servlets and JavaServer Pages". 1st edition. JSP 1.1 Available for free at his site. 'More Servlets ..." Covers JSP 1.2 "Core Servlets and JavaServer Pages". 2nd edition. JSP 2 Good books, this series covers the API's better than most but the sample apps are very lame!
