.NET CF connects to Java via CORBA

An article from the December issue of .NET Developer’s Journal discusses how to connect a device running the .NET Compact Framework with a Java back-end via CORBA.  This article uses MiddSol’s MinCor.NET, which is is an object request broker for the Compact Framework written in C#. It supports Windows Mobile, Windows XP Embedded, and Windows CE…

Multi-language support, interop, and philosophy

I had a comment on the J# serialization post that I took as , “J# is insufficient to entice J2xE developers.”  J# isn’t really about enticing developers “away from” a different platform.  [ by my view, that is a pretty narrow way of looking at the world of developers anyway, as if there was only a…


Java and .NET – Java serialization vs XML

To recap – yesterday we all learned that Java and .NET can interop using Java serialization.  J# includes this capability, so serializing a J# class and shipping it over to a Java (JDK 1.4.1) app actually works.  The opposite direction also works.  The interesting question from yesterday was, how does the performance of interop using…


Java Serialization and .NET – There Really *is* a Santa Claus

Ah, yup, it works. You can take a single class (SomeType.java), marked with ISerializable, and then compile it twice – once with javac.exe, and once with vjc.exe.  Serialize from Java and you can de-serialize from J#.  and vice versa.  It works in both directions.   If you do this, the .NET app is not limited to…


Java serialization and .NET?

Quiz:  What do you think?    Java has a binary serialization format.  .NET has J#, which includes the JDK 1.1.4 class libraries, which includes Java serialization.  Will it be possible for a Java app running under JDK 1.4 to serialize an object graph to a stream, and then de-serialize that object graph in .NET?   We are…


on Java-to-.NET interop via JMS and MQSeries

While looking around I found two articles, from SYS-CON’s WebSphere Developer’s Journal,  covering J2EE and .NET interop via MQSeries. part 1: http://sys-con.com/story/?storyid=43430&DE=1#RES part 2: http://sys-con.com/story/?storyid=43452&DE=1#RES These articles reference ma7p, the IBM supportpac, which is no longer available.  ma7p has graduated into the MQSeries product.  Upgrade to MQ V5.3 + CSD05 or later to get the…


A Month of Interop

Microsoft is planning a month’s worth of webcasts exploring interop from numerous angles, check it out: http://www.interopmonth.com/ or http://blogs.msdn.com/msdnwebcasts/archive/2004/11/20/266983.aspx


Call .NET ASMX from ASP

Let’s say you have an ASMX webservice written in C# or VB.NET or some other .NET language, and you want to call it from an ASP page written in VBScript. There are a couple of ways to do this. Use the MS Soap Toolkit.http://www.microsoft.com/downloads/details.aspx?FamilyId=C943C0DD-CEEC-4088-9753-86F052EC8450&displaylang=en But as the download page states, this toolkit will be retired…


DataGrid and Web Services

Didya ever wonder?… why DataGrids and other data-bound controls can use arrays of objects as data sources, but they display only public properties (not fields)? On the other hand, types generated by wsdl.exe or xsd.exe generally expose public fields (not properties).   Do you think the xsd.exe people talked to the DataGrid people?   Ok, I know,…
