Dinamica news

1 .- After two years of inactivity,the driver was updated open? jTDS source for SQLServer,we will be updating our distro? Tomcat 6 in the coming days to incorporate this change,but? you can do now:? * Http://sourceforge.net/projects/jtds/? 2 .- There JDK update,1.6 update 17. No improvements or corrections? significant for an AppServer,we are still using as a basis? the update 15,but I meet tell them.? * Http://java.sun.com/javase/downloads/widget/jdk6.jsp? 3 .- In these days we touch build an interesting application,a? standalone client,which must run as a service on hundreds of PCs,and? communicates via SSL with an Dinamica webapp running in a Tomcat.? Two things to note:? We got a utility that allows you to mount a Java class as a service? Windows,and it was very easy to do,only. Ini file and a. Exe are in the same directory as our class and other JARs. The product? is called "Java Service Launcher for Windows" or JSL:? * Http://jslwin.sourceforge.net? I recommend it,is both 32 and 64 bits. We tested it on XP? 32 bits. With this product it was possible to make an installation package? it is decompressed,is executed. BAT and ready,you register as? service.? This programmed client uses a very simple technique to get? a Recordset via SSL,and the side of the webapp is even easier,just? must use a class called dinamica.DataOutput that "prints" the? recordsets in bytes as a response of Action:? xml version = '1 .0 'encoding =' ISO-8859-1 '?>? <config>? <summary>? Returns a recordset via http (s) with outstanding tickets for a client PC? </ summary>? <log> false </ log>? <transaction>? <classname> dinamica.GenericTransaction </ classname>? <validator> true </ validator>? <transaction> false </ transaction>? <jdbc-log> false </ jdbc-log>? <recordset id="query.sql" source="sql" scope="transaction"/>? </ transaction>? <output>? <classname> dinamica.DataOutput </ classname>? </ output>? </ config>? The client uses this function and generic utility to receive a HashMap with one or more recordsets,given the URL of Action:? / **? * Retrieve HashMap containing one or more recordsets? * @ Param url? * @ Param logStdout? * @ Return? * @ Throws Throwable? * /? @ SuppressWarnings ( "unchecked")? Recordset> <string,getTickets public HashMap (String url) throws Throwable? (? / / connect via HTTP? URL page = new URL (url);? HttpURLConnection urlc = (HttpURLConnection) page.openConnection ();? urlc.setUseCaches (false);? / / test for http errors? int retcode = urlc.getResponseCode ();? RetMsg = urlc.getResponseMessage String ();? if (retcode> = 400)? throw new Throwable ( "HTTP Error:" + retcode + "-" + retMsg); / / read and convert byte stream to HashMap? ObjectInputStream in = new ObjectInputStream (new? BufferedInputStream (urlc.getInputStream (),urlc.getContentLength ()));? Recordset> <string,HashMap map = (HashMap <String,? Recordset>) in.readObject ();? in.close ();? return map;? )? 4 .- There are new versions of iText and JFreeChart components,which? are used by Dynamics within a webapp. You are welcome? update their projects with new JARs of these components,? esten pendientes but these people sometimes discontinue or delete? some APIs and this could affect some of their classes or? framework. Although Francis and running the latest itext and besides? offer something new and useful way to the hair Dynamics. Also? There JExcelAPI component update. The URLs are if you want? update or download the latest sources:? * Http://sourceforge.net/projects/jexcelapi/? * Http://www.jfree.org/jfreechart/? * Http://www.lowagie.com/iText/? Regards to all,?
