Using

'Type Initializer' Exception

CivilGuy — 2010-08-27T16:29:50Z

I've got the JaNetSE jddk installed (latest version), and I've compiled a java code project I've got in process, no apparent real problems (several warnings, but no errors - and no surprises, given the work-in-progress), but then:

FWIW, I've also checked and confirmed that .NET version 3.5 sp1 is installed. Any ideas as to what's wrong here? Anything else I should check for?

Visual Studio Integration

Is Visual Studio integration possible? Or do we have to use some Java IDE like eclipse?

Resolving type errors

tarik — 2010-03-18T13:24:45Z

Hi there For anyone has the time to try it I'm trying to compile the METS java toolkit http://hul.harvard.edu/mets/ in order to get a dll and use it in Visual Studio C#. This should be no problem but I get compiler errors.

So Actuate.java is in this local folder and the jar is in the bin folder

C:\METS_Toolkit\classes\edu\harvard\hul\ois\mets>C:\Ja.NET\bin\javac -classpath C:\METS_Toolkit\bin\mets.jar Actuate.java –nowarn Not setting the jar with the classpath results in one extra error, this: 1. ERROR in Actuate.java (at line 13) import edu.harvard.hul.ois.mets.helper.*; ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The import edu.harvard.hul.ois.mets.helper cannot be resolved So adding the jar to the classpath definitely fixes this error but the 4 below remain 1. ERROR in Actuate.java (at line 23) extends edu.harvard.hul.ois.mets.helper.Enum ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ edu.harvard.hul.ois.mets.helper.Enum cannot be resolved to a type ---------- 2. ERROR in Actuate.java (at line 57) super (value); ^^^^^^^^^^^^^^ The constructor Object(String) is undefined ---------- 3. ERROR in Actuate.java (at line 70) throws MetsException ^^^^^^^^^^^^^ MetsException cannot be resolved to a type ---------- 4. ERROR in Actuate.java (at line 80) throw new MetsException ('Unsupported actuate behavior: ' + name); ^^^^^^^^^^^^^ MetsException cannot be resolved to a type ---------- 4 problems (4 errors) I have tried this with the normal Sun javac and it compiles fine. Anyone know what the problem is? Thanks for any help Tarik

The first try of the post got lost, but I don't know why?! ;) I have downloaded Java.Net and installed it on a machine with Visual Studio 2008 and .NET 3.5. For the first HelloWorld I copied your code from the Using section. When I run the javac I get funny exceptions. Maybe you can give me a hint, what it could be. ;) C:\Program Files\Java.Net\jdk\bin>java -version Apache Harmony Launcher : (c) Copyright 1991, 2008 The Apache Software Foundatio n or its licensors, as applicable.

anyone try using this on a 64 bit windows machine? i figured it would be able to work in the x86 environment but no suck luck yet.

log messages with visual studio

utahgetmetwo — 2009-10-14T16:18:22Z

anyone know what needs to be done to get logging to work with visual studio output? with eclipse i get log messages, with VS i get Unable to get symbol reader for assembly. I'm guessing i need to manually add the logging upon initializing the java objects from c#...i have a java package that i converted to a dll via bam.

Getting runtime java.lang.ExceptionInInitializerError

rvanamb — 2009-09-09T15:58:00Z

Hi,

First I want to say that I love the work you have done developing Ja.NET. This is a really useful tool to have in the tool box!

First issue is that I am getting a runtime exception when calling java code from a .NET 3.5 WPF application (code below).

A first chance exception of type 'java.lang.ExceptionInInitializerError' occurred in janet.awt.dll java.lang.ExceptionInInitializerError: The type initializer for 'org.apache.harmony.awt.nativebridge.NativeBridge' threw an exception.

Second issue: Is there a way to add the Java gui component to a StackPanel? or (not prefered) a Windows Form?

Build steps:

1) create java app in Netbeans (JDK 1.6.0_16-b01)

2) C:\Ja.NET\bin\javac.exe -bam:javaapplication.dll .\JavaApplication\src\javaapplication\*.java

3) create C# project

4) add references to C:\Ja.NET\jre\bin\default\*.dll

5) add reference to javaapplication.dll

sleary — 2009-08-25T16:14:10Z

Every time i try to use the JaNetSe compiler from within eclipse i get the following error. The type java.lang.Object cannot be resolved I'm on eclipse 3.4 and using the Java Builder. Googling i find that i am missing rt.jar which does not appear to exist in the janetset installation folder. What am i doing wrong? Stephen

problems compiling in eclipse

sleary — 2009-08-26T08:33:43Z

First post also got lost

When i try to compile something in eclipse (by setting the JDK to Ja.NET se) i get the following error.

Cannot find the class file for java.lang.Object. Fix the build path then try building this project

Googling for this error i find that i should add rt.jar to the build but Ja.NET SE does not seem to have this

Thoughts/ideas?

Errors while compiling JExcelAPI

iley — 2009-06-20T20:51:48Z

I've just installed Ja.Net and I hope to use it for porting 'http://jexcelapi.sourceforge.net'>JExcelAPI for .Net platform. I've tried to compile it by running:c:\jexcelapi> javac -bam:jxl.dll -classpath src src/*.java

The compilation have failed with 14 errors. What can I do to compile the library?

Help needed For .Net developer (with very limted java knowledge)

bradman — 2009-04-02T16:52:49Z

Hello, We are currently using VS2005 for our jsharp and .Net (winforms) development. Our jsharp code is a shared java code between .Net app and backend web-based app. We are trying to migrate into VS 2008 and hopefully use JaNet to build java shared code into .Net assembly. I am an experienced C# .Net developer but have very limited knowledge in java. i often change the shared java objects to add more private fields and getter/setters and change the logic classes little bit to provide additional functionality. I was able to make the java changes with in VS 2005 IDE and compile it and use it in C# code. Since VS 2008 doesn't have support for jsharp code, I need to find another IDE to make the java changes and compile using Janet and BAM. I want to use Eclipse IDE (or any other IDE) and some how tell it to use Janet and BAM to create the output .Net assembly. Can you tell me how to achieve what I am looking for? Thanks in advance.

Unbound Wildcards Support

CloudCreator — 2009-04-04T21:25:20Z

Hi, I just stumbled upon your website, looks interesting.

I have a couple of questions.

How do u deal with unbound wildcards and generic covariance and contravariance?

Can I do this

Something objSon = new Something();

Something objFather = objSon, where

Class Son extends Father

{}

and also

Do u support Something ?

thanks.

Eclipse Integration

michael.rinner@profactor.at — 2009-01-07T08:05:09Z

Hey,

an integration into eclipse ide is possible with ANT by adding the following example target to the build.xml:

the build.jaNET_compiler path variable must be set to the javac.exe location in your file system. In case only the .dll file is needed, the line

can be added within the task

best wishes,

Michael

Applets in Ja. NET

zeeshanejaz — 2008-12-29T07:33:07Z

Are applets supported? What will be the client side requirements if we end up compiling an applet in Ja. NET? Will the tag be replaced by an tag in HTML?

Remoting RMI

daniel.manzke — 2008-12-17T12:19:44Z

Hi,
in the next time I will give Java.NET a try. We have developed a java application which uses RMI for its connectors. I saw in your Documentation that you have implemented the java.rmi package. So is it possible to run a java application on .NET and use the Java RMI features?
So I could run the server with .NET and its features and connect with a normal Java RMI application?

Thanks,
Daniel
