A sample server that illustrates Non-Blocking Socket I/O can be found at http://www.owlmountain.com/tutorials/NonBlockingIo.htm.

In JDK 1.4, there is an Endorsed Standards Override Mechanism which can be used to override the classes in the JDK itself. One way to replace the classes in the JDK with the classes contained in a set of jar files is to place the jar files in some directory, "my-endorsed", and define a system property. For example, to use a newer version of Xalan, place the newer version of xalan.jar in the "my-endorsed" directory and invoke the Java launcher with the -Djava.endorsed.dirs= my-endorsed option.

A pitfall to avoid: Don't assume that SSL_read() will just read from the underlying transport or that SSL_write() will just write to it -- it is also possible that SSL_write() cannot do any useful work until there is data to read, or that SSL_read() cannot do anything until it is possible to send data.

Using non-blocking I/O means that you have to poll sockets to see if there is data to be read from them. Polling should usually be avoided since it uses more CPU time than other techniques. Using SIGIO allows your application to do what it does and have the operating system tell it (with a signal) that there is data waiting for it on a socket.

To prevent the TCP connect from blocking, you can set the socket to non-blocking mode. Then when you do the connect(), you will either connect immediately (unlikely) or get an exception that contains the error number as .errno. errno.EINPROGRESS indicates that the connection is in progress, but hasn't finished yet. Different OSes will return different values, so you're going to have to check what's returned on your system. You can use the connect_ex() method to avoid creating an exception.

How to implement persistent objects in Python? (Persistent == automatically saved to and restored from disk.)

To answer my own question... I uninstalled 1.5 and installed 1.4. Compiled and works fine. I suspect this is actually a problem with Ant. Is it possible to extend for example the form object in Flow? So that we have our own implementation of it? If so, are there examples. ps why was Flow written in javascript, and not java? Probably a stupid one:). Do you serialize it to JPG or PNG? Otherwise this error can not occur. But if, it's of course no longer SVG.

Signal-chaining enables the Java Platform to better interoperate with native code that installs its own signal handlers. The facility works on both Solaris and Linux platforms. The signal-chaining facility was introduced to remedy a problem with signal handling in previous versions of the Java Hotspot VM. Prior to version 1.

Retroweaver is a Java bytecode weaver that enables you to take advantage of the new 1.5 language features in your source code, while still retaining compability with 1.4 virtual machines. Retroweaver rewrites class files so that they are compatible with older virtual machines. Check out http://sourceforge.net/projects/retroweaver .

Java Swing GUI applications (including JDebugTool) can hang in JDK 1.4. The work around is to add the following argument to java -Dsun.java2d.noddraw=true

The following document describes what you need to do to get JDK 1.4 (also known as Java 2 version 1.4) operational on your iSeries running OS/400 V5R1 : http://www-912.ibm.com/s_dir/slkbase.NSF/1ac66549a21402188625680b0002037e/0581029cdbcafcbd86256c4f00673b7d?OpenDocument

Although both APIs are conceptually similar, the log4j API is significantly more flexible and offers many more features, too numerous to be listed here. You will discover that the additional features and flexibility turn out to be indispensable in the context of a mission-critical application. The open and collaborative way in which log4j is developped ensures that it continues to preserve and even widen its competitive edge.

Polling applies only to the the dequeueing of DMA capture buffers via dc1394_capture_dequeue_dma(); it is an argument of that function. If you set the dc1394video_policy_t argument of this function to DC1394_VIDEO1394_POLL the function will not wait for frames if the DMA ring buffer is empty. It will return immediately either with the first frame waiting in the DMA ring buffer or with a NULL pointer if no frame is present.

Polling applies only to the DMA capture functions (the ones with "_dma_" in their names). The non-polling capture functions (also called blocking capture functions) always return a valid pointer to a frame (barring some other error).

JDK 1.4 supports Interoperable Object References (IORs). To use the JDK 1.4 ORB with the TAO Naming Service server: Start TAO Naming Service server: $ $TAO_ROOT/orbsvcs/Naming_Service/Naming_Service -ORBListenEndpoints iiop://host:port Then, run the JDK 1.

Special care must be taken with the socket until healing is complete. In the immediate time period after your surgery, the closed eyelid should be wiped gently with a cotton ball moistened with the sterile eye solution given to you when you are discharged; drops or ointment may also be prescribed. This helps to keep the socket free from infection. The healing process usually takes about two to four weeks. When you receive your ocular prosthesis, you may wash your face normally.

In order for the Java communications API to find ports the file javax.comm.properties must be in the correct place. The preferred location is in <jdk>/lib. See the installation instructions for alternate locations and further information.

The Java 2 SDK, Enterprise Edition 1.4 (J2EE 1.4 SDK) is a complete package for developing and deploying J2EE 1.4 applications. The J2EE 1.4 SDK contains the Sun Java System Application Server Platform Edition 8, the J2SE 1.4.2 SDK, J2EE 1.4 platform API documentation, and a slew of samples to help developers learn about the J2EE platform and technologies and prototype J2EE applications. The J2EE 1.4 SDK is for both development and deployment.

Sampling is the use of an excerpt of pre-recorded material within another recording, and so sampling requires a master use right (see above).

You can block or unblock other members at any time and for any reason. Blocking prevents other members from sending you emails, winks or can be used to avoid chatting directly with other members. LinkAll Personals strongly encourages you to block any member who behaves in an abusive manner and report the behavior to abuse@LinkAll Personals.

This premium feature prevents your name and number from displaying on the Caller ID display units of the people you call. If the person you are calling has a Caller ID display unit, they will see "Private" or "Anonymous" displayed when you call them.

Blocking is available to all members. If someone blocked you it was probably because they preferred to keep their distance.

If you don't have an Ada 95 compiler but have a POSIX binding, there is a package using POSIX services that provides non-blocking, keystroke-at-a-time access to the terminal. It is available by FTP in file ftp://lglftp.epfl.ch/pub/Ada/FAQ/inkey.ada

We recommend 2-10 days of ‘normal’ operation, meaning no attacks, no unusual events causing high traffic conditions (e.g. news releases or promotions on a web server). This may vary depending on how much traffic parameters fluctuate throughout the day.
