As outlined in the <a href="http://trephine.org/t/index.php?title=Docs/trephine.js" title="Docs/trephine.js">trephine.js documentation</a>, the options hash for <code>trephine.load()</code> now recognizes a new parameter: <code>onerror</code>. </p><p>If an <code>onerror</code> function is specified, it will be executed in the event that the browser was unable to load the trephine applet. This could be for any of several reasons, the most common being a lack of Java support. That is, if the user does not have Java 1.5 or higher, then the trephine applet will fail to load, and trigger execution of the onerror handler (if supplied). </p><p>At this time only the <a href="http://trephine.org/t/index.php?title=Executing_arbitrary_script" title="Executing arbitrary script">executing arbitrary script</a> demo features an onerror handler, but I plan to add similar handlers to all the other demos soon. This is a very minor enhancement, and doesn't change any existing APIs, so trephine's version number will not be incremented. </p><p>Hopefully this will make it easier for consumers to gracefully degrade in the face of Java-less browsers.

That is, a <a href="http://trephine.org/t/index.php?title=Home" title="Home">trephine</a> application which allows the user <a href="http://trephine.org/t/index.php?title=File_browser" title="File browser">to browse</a> for an Excel file on their system, then extract the relevant data and convert it into something more useful. </p><p>By using <a href="http://poi.apache.org/" class="external text" title="http://poi.apache.org/" rel="nofollow">Apache POI</a>, such an app could show Excel data in an HTML table, or export to CSV, JSON or XML. It would also be possible to allow the user to pick and choose certain columns to export, or delete rows, etc. And it should be no problem to include the capability to post the data back to a web service - either directly as text, or after a round compression (zip or gzip). </p><p>I wanted to have a demo ready to announce today, but it's a bit more complex to produce than I had at first anticipated, so unfortunately it'll be a few more days before I get it out there. </p><p>Does this sound useful to you?

In the case of JRuby support though, all available platforms were tested and passed. </p><p>I'm really excited about this new capability. There's a certain allure to developing desktop quality applications, written in the developer's choice of language and delivered through the browser. </p><p>Enjoy! As usual, I look forward to your comments.&nbsp;:) </p><p>[<a href="http://trephine.org/t/index.php?title=Trephine_adds_Ruby_support" title="Trephine adds Ruby support">read more ...</a>] (<a href="http://trephine.org/t/index.php?title=Trephine_adds_Ruby_support#disqus_thread" title="Trephine adds Ruby support">view comments</a>) </p><p>--<a href="http://trephine.org/t/index.php?title=User:Jimbojw" title="User:Jimbojw">Jim R.

<p><i>From <a href="http://trephine.org/t/index.php?title=Announcing_trephine_version_1.2" title="Announcing trephine version 1.2">Announcing trephine version 1.2</a></i>: </p><p>Shortly after releasing version 1.1, it became clear that a few more features were necessary for the more fully featured demos to come. This latest version includes two major enhancements: </p> <dl><dt>addSystemJar() </dt></dl> <p>The executor thread object now has an additional method called <code>addSystemJar()</code> which effectively splices in a given jar into the System classpath. It can be specified as a string, File, URI or URL. This was necessary to make other Java scripting engines (JRuby, Jython, etc) available at runtime. </p><p>Example usage (Java context): </p> <div dir="ltr" style="text-align: left;"><div class="javascript source-javascript" style="font-family:monospace;"><pre class="de1">java.<span class="me1">lang</span>.<span class="me1">Thread</span>.<span class="me1">currentThread</span><span class="br0">&#40;</span><span class="br0">&#41;</span>.<span class="me1">addSystemJar</span><span class="br0">&#40;</span><span class="st0">'/path/to/some.jar'</span><span class="br0">&#41;</span>;</pre></div></div> <dl><dt>JSON </dt></dl> <p>Both the browser JavaScript portion of trephine (<code><a href="http://trephine.org/t/index.php?title=Docs/trephine.js" title="Docs/trephine.js">trephine.js</a></code>) and the Rhino JavaScript context now include a JSON encoder. This means it is no longer necessary for developers to provide a JSON implementation to realize better communication between the browser and Java contexts. </p><p>Example usage (browser context): </p> <div dir="ltr" style="text-align: left;"><div class="javascript source-javascript" style="font-family:monospace;"><pre class="de1">trephine.<span class="me1">toJSON</span><span class="br0">&#40;</span>value<span class="br0">&#41;</span>;</pre></div></div> <p>Example usage (Java context): </p> <div dir="ltr" style="text-align: left;"><div class="javascript source-javascript" style="font-family:monospace;"><pre class="de1">JSON.<span class="me1">stringify</span><span class="br0">&#40;</span>value<span class="br0">&#41;</span>;</pre></div></div> <p>The implementations are identical, and adapted from Douglas Crawford's excellent <a href="http://www.json.org/json2.js" class="external text" title="http://www.json.org/json2.js" rel="nofollow">json2.js</a> script. </p><p>Now that these infrastructural pieces are complete, the other language demos (starting with JRuby) will be posted shortly. </p><p>[<a href="http://trephine.org/t/index.php?title=Announcing_trephine_version_1.2" title="Announcing trephine version 1.2">read more ...</a>] (<a href="http://trephine.org/t/index.php?title=Announcing_trephine_version_1.2#disqus_thread" title="Announcing trephine version 1.2">view comments</a>) </p><p>--<a href="http://trephine.org/t/index.php?title=User:Jimbojw" title="User:Jimbojw">Jim R.

<p><i>From <a href="http://trephine.org/t/index.php?title=Announcing_trephine_version_1.1" title="Announcing trephine version 1.1">Announcing trephine version 1.1</a></i>: </p><p>After waves of rigorous testing, trephine version 1.1 is here! In this release you'll find a number of enhancements and fixes, of which these are a few: </p> <ul><li> Expanded <a href="http://trephine.org/t/index.php?title=Platform_support" title="Platform support">platform support</a> including fixes for support for Safari on Mac OS 10.4 (Tiger) </li><li> Better failover between direct applet communication and anonymous marshaller </li></ul> <p>But perhaps the most important feature of version 1.1 is that the source code for the trephine core is available for the first time from the <b><a href="http://trephine.org/t/index.php?title=Download" title="Download">download</a></b> page. There are two licensing options available: </p> <ul><li> If you're just curious to take a peek under the hood, there's a <a href="http://trephine.org/t/index.php?title=Trephine_Research_Only_Evaluation_Agreement" title="Trephine Research Only Evaluation Agreement">Research Only Evaluation Agreement</a> </li><li> If you're looking to build your own jar(s) from the source and host them yourself, there is now a <a href="http://trephine.org/t/index.php?title=Trephine_Commercial_License" title="Trephine Commercial License">Commercial Developer License</a> </li></ul> <p>Note that the download page has more information about which license is applicable in which situations. </p><p>Of course, if you only want to <i>use</i> trephine, then hotlinking is still the best option (see <a href="http://trephine.org/t/index.php?title=Getting_started" title="Getting started">Getting started</a> for instructions). </p><p>Enjoy!

<p><i>From <a href="http://trephine.org/t/index.php?title=Launching_trephine.org_project_blog" title="Launching trephine.org project blog">Launching trephine.org project blog</a></i>: </p><p>Welcome to the <a href="http://trephine.org/t/index.php?title=Home" title="Home">trephine.org</a> <strong class="selflink">project blog</strong> - the best place to find information on the project status, release announcements, bug fixes, and technical development updates. Hopefully this will engender the kinds of discussions which have already begun on the <a href="http://trephine.org/t/index.php?title=Shell_commands" title="Shell commands">shell commands</a> and <a href="http://trephine.org/t/index.php?title=File_browser" title="File browser">file browser</a> demo pages. </p><p>I have a long backlog of articles to write about a variety of trephine related topics, as well as many more <a href="http://trephine.org/t/index.php?title=Demos" title="Demos">demos</a> to write and publish. Here's a short list of some of the more immediate project goals: </p> <dl><dt>Broadening language support </dt></dl> <p>Create demos for most or all of the <a href="http://en.wikipedia.org/wiki/List_of_JVM_languages#High-profile_languages" class="extiw" title="wikipedia:List_of_JVM_languages">high-profile JVM languages</a>, especially JRuby, Jython, Groovy and Scala. </p> <dl><dt>TrephineHttpRequest </dt></dl> <p>Create an <tt>XMLHttpRequest()</tt> clone which uses trephine (and probably <a href="http://hc.apache.org/httpclient-3.x/" class="external text" title="http://hc.apache.org/httpclient-3.x/" rel="nofollow">HttpClient</a>) as its transport mechanism. This would allow user opt-in unrestrained cross-domain requests, something the web has needed for quite some time. </p> <dl><dt>Real applications </dt></dl> <p>Although demos are really great at pointing out individual features, to really illustrate the capabilities of a trephine based web application it will be necessary to generate a few full-featured applications. </p><p>This list is just the beginning, so please post your suggestions as to what you'd like to see out of trephine. I look forward to hearing from you! </p><p>[<a href="http://trephine.org/t/index.php?title=Launching_trephine.org_project_blog" title="Launching trephine.org project blog">read more ...</a>] (<a href="http://trephine.org/t/index.php?title=Launching_trephine.org_project_blog#disqus_thread" title="Launching trephine.org project blog">view comments</a>) </p><p>--<a href="http://trephine.org/t/index.php?title=User:Jimbojw" title="User:Jimbojw">Jim R.
