Lucene 3.0 is out

2009-11-26T04:46:00.000-08:00

Great news: Lucene 3.0 is out!!

The new version is mostly a cleanup release without any new features. All deprecations targeted to be removed in version 3.0 were removed.

See CHANGES.txt for details.
Binary and source distributions are available here

ANTLR 3.2 is out

2009-09-24T02:38:00.000-07:00

New features

Added tree grammar filter=true mode. See Tree pattern matching
Added misc.FastQueue and TestFastQueue: A queue that can dequeue and get(i) in O(1) and grow arbitrarily large. A linked list is fast at dequeue but slow at get(i). An array is the reverse. This is O(1) for both operations.
Added tree.TreeIterator, a generator that walks a doubly-linked tree. The nodes must know what index they are. It's an Iterator but remove() is not supported. Returns navigation nodes always: UP, DOWN, EOF.
Added misc.LookaheadStream: A lookahead queue that knows how to mark/release locations in the buffer for backtracking purposes. I hope to use for both tree nodes and tokens. Just implement nextElement() to say how to get next node or token.

My workspace part 1

2009-09-23T11:04:00.000-07:00

Eclipse installation. Different Eclipse builds for different needs can be found "Eclipse Downloads". I preferred Eclipse IDE for Java Developers or Eclipse IDE for Java EE Developers. More about difference you can found.

Original source Alexey Zavizionov

Unpack tar.gz

2009-09-08T05:32:00.001-07:00

To unpack the archive in the form *. tar.gz use the command:

tar xvfz *. tar.gz

Used in the command keys

x - allows you to retrieve files from the archive.
v - concludes tar detail. This means that the screen will be displayed all found in the archive files. If this option is omitted, the output of the processing will be limited.
f - is a mandatory option. Without it, tar tries to use tape instead of the archive file.
z - lets you handle archive, compressed gzip (with extension. gz). If you omit this option, tar will report an error. Conversely, this option should not be used for uncompressed files.

Jprofiler 5.2.2 and Java 5 64-bit

2009-07-08T02:31:00.000-07:00

When I tried to run Jprofiler , I received : exception in thread "main" java.lang.InternalError: libXt loaded before libXm .

Exception in thread "main" java.lang.InternalError: libXt loaded before libXm
 at java.lang.ClassLoader$NativeLibrary.load(Native Method)
 at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1751)
 at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1668)
 .....

Workaround is to change AWT_TOOLKIT. You should add “export AWT_TOOLKIT=XToolkit” to you jprofiler5/bin/jprofiler file.

LD_LIBRARYN32_PATH="$app_home/bin/linux-x86:$LD_LIBRARYN32_PATH"
LD_LIBRARYN64_PATH="$app_home/bin/linux-x86:$LD_LIBRARYN64_PATH"
export LD_LIBRARY_PATH
export DYLD_LIBRARY_PATH
export SHLIB_PATH
export LIBPATH
export LD_LIBRARYN32_PATH
export LD_LIBRARYN64_PATH
export AWT_TOOLKIT=XToolkit

How to copy one file to another through channel

2009-07-05T08:19:00.000-07:00

This Java tips illustrates a method of copying one file to another file through channel. A channel is created both on source as well as destination and then the file is copied between those two channels.

   try {
           // Create channel on the source
           FileChannel srcChannel =
             new FileInputStream("srcFilename").getChannel();
      
           // Create channel on the destination
           FileChannel dstChannel =
             new FileOutputStream("dstFilename").getChannel();
      
           // Copy file contents from source to destination
           dstChannel.transferFrom(srcChannel, 0, srcChannel.size());
                   // Close the channels
         srcChannel.close();
         dstChannel.close();
       } catch (IOException e) {
         //TODO catch exception
       }
