about socket reuse in RMI
by zhang Jackie 26 Jun '07

26 Jun '07

hi socket reuse in RMI confused me much for several reasons: In my opionion, one socket is boud some information about server and port(right?), how such socket can be reused to communicate to another server,just change the IP address and port number? Is it possible to do so in user space of linux? ServerSocket is used to accept new connection, one ServerSocket instance can fit the need of application, why reuse is needed. What the socket reuse of RMI means? Some one give me such a comment: *RMI will reuse sockets if the socket was created by the same socket factory. So, if two remote object's socket factories that are .equal() then RMI will reuse a client's socket to talk with each RMI object. It will also reuse that socket for multiple calls to those remote objects. * So this is not socket factory reuse ,rather than socket reuse. I was confused greatly, Do everyone can give me a clear explanation about this topic? thanks for any reply!

External zlib patches
by Anthony Petrov 14 Jun '07

14 Jun '07

Hello folks, Some time ago Diego Pettenò sent out a couple of patches that allow JDK use an external zlib library. A number of other fixes from this author sent to the awt-dev@ alias depend on the mentioned zlib patches, and cannot be easily applied without the zlib-patch applied first. Could anyone confirm whether the zlib-patches are currently being considered to be applied? -- best regards, Anthony

[Patch] Patch for javax.xml.parsers.DocumentBuilder
by Jeffrey Haškovec 14 Jun '07

14 Jun '07

Is it possible to get 2 more parse methods added to DocumentBuilder as below: /** * Parse the content of the given <code>Reader</code> as an XML * document and return a new DOM {@link Document} object. * An <code>IllegalArgumentException</code> is thrown if the * <code>Reader</code> is null. * * @param is Reader containing the content to be parsed. * * @return <code>Document</code> result of parsing the * <code>Reader</code> * * @throws IOException If any IO errors occur. * @throws SAXException If any parse errors occur. * @throws IllegalArgumentException When <code>is</code> is <code>null</code> * * @see org.xml.sax.DocumentHandler */ public Document parse(Reader reader) throws SAXException, IOException { if (reader == null) { throw new IllegalArgumentException("Reader cannot be null"); } InputSource in = new InputSource(reader); return parse(in); } /** * Parse the content of the given <code>Reader</code> as an * XML document and return a new DOM {@link Document} object. * An <code>IllegalArgumentException</code> is thrown if the * <code>Reader</code> is null. * * @param is Reader containing the content to be parsed. * @param systemId Provide a base for resolving relative URIs. * * @return A new DOM Document object. * * @throws IOException If any IO errors occur. * @throws SAXException If any parse errors occur. * @throws IllegalArgumentException When <code>is</code> is <code>null</code> * * @see org.xml.sax.DocumentHandler */ public Document parse(Reader reader, String systemId) throws SAXException, IOException { if (reader == null) { throw new IllegalArgumentException("Reader cannot be null"); } InputSource in = new InputSource(reader); in.setSystemId(systemId); return parse(in); } Basically InputSource will already accept a Reader. StringBufferInputStream is deprecated and says to use StringReader. DocumentBuilder won't parse a reader, so my problem is I can't parse an XML file that I have as a String in Memory. Thanks for your consideration, Jeffrey Haskovec

[PATCH] Identify language and country based on LC_MESSAGES rather than LC_CTYPE
by Diego 'Flameeyes' Pettenò 12 Jun '07

12 Jun '07

Hi, The attached patch changes the code that currently parses LC_CTYPE to set encoding, encoding variants, language and country to use LC_CTYPE just to set the encoding, and instead uses LC_MESSAGES to set country and language. The reason for this change si that in a system where LC_MESSAGES is set to English, you'd expect Java to answer in English, rather than Italian by default (this is true for both JDK's commands and for Java-based interfaces). The patch is probably rough, so I'd be happy to hear comments on what to improve of it. -- Diego "Flameeyes" Pettenò http://farragut.flameeyes.is-a-geek.org/

[PATCH] Add option to use external zlib (without awt/splashscreen changes)
by Diego 'Flameeyes' Pettenò 08 Jun '07

08 Jun '07

Hi, as I've just mailed to awt-dev a reduced copy of my previous external-zlib patch that only changes splashscreen support (as it's needed for external jpeg/giflib/libpng), I'm sending back a new copy of external-zlib that excludes that particular part. -- Diego "Flameeyes" Pettenò http://farragut.flameeyes.is-a-geek.org/
