Re: [xmlvm-users] External static library issues

[Arno P. <ar...@pu...>]

note that both problems don't exist in the C backend. String.isEmpty() 
is cross-compiled from the Harmony implementation and the stylesheet 
contains the missing byte code instruction (in xmlvm2c.xsl). That one 
instruction you can just copy-paste to xmlvm2objc.xsl if you want to 
continue using the Objective-C backend.

[xmlvm-users] External static library issues

[Ian F. <ifr...@gm...>]

Hello,
Just wanted everyone to know that I was able to confirm that my issues are
definitely related to housing all of the compat sources file in a cocoa
static library.  Once I built them directly into my project I began to have
success.  Although I'd be interested to know why the issues exist, its not a
big deal for me.
I do have a couple of things to note for you:

1. java_langString.m has error in isEmpty:

- (int) isEmpty__
{
return [self length] > 0;
}

should be == 0

2. Use of the >> operator in java results in the following output from the
compiler (not associated with any particular file being processed, just at
the end):

<dex:shr-int xmlns:dex="http://xmlvm.org/dex" xmlns:vm="http://xmlvm.org"
vx="8" vx-type="int" vy="9" vy-type="int" vz="8" vz-type="int"/>

The "ERROR" call is in the source file using it.  Using >>> (unsigned shift)
works though.

So far so good, getting good results from what I've built so far.  Great job
with this took kit, very impressive.

Best Regards,

Ian

[xmlvm-users] Linker error help

[Ian F. <ifr...@gm...>]

Trying to simplify my issues related to an earlier post now I'm running into
a linker error I didn't see before - not sure why yet.


Anyone ever seen this when trying to link in static library with lib compat
xmlvm files (objective-c) ?


"_JAVA_NULL", referenced from:

_JAVA_NULL$non_lazy_ptr in libTest.a(com_newsdart_client_NDxmlVmTest.o)

(maybe you meant: _JAVA_NULL$non_lazy_ptr)

[xmlvm-users] Using XMLVM to generate a Cocoa library

[Ian F. <ifr...@gm...>]

Hello,

I have been experimenting using XMLVM to generate an iPhone compatible
library from java source meant to be the API on the Android side.  I'm not
trying to generate a full app for the iPhone using XMLVM, just an API
library.

I generated the objective C files, built a library using those files and
your compatability files for objective C.  Now I'm trying to use that
library in a native iPhone application.

My problem is that the implementation categories don't seem to be referenced
properly as I see two things:

1 - warning like this:

: warning: incompatible Objective-C types 'struct java_lang_String *',
expected 'struct java_lang_String *' when passing argument 1 of
'__init_com_newsdart_client_NDApi___java_lang_String:' from distinct
Objective-C type


2 - runtime selector exception on this line in the generated code for one of
my classes:


    [((java_lang_Object*) _r2.o) __init_java_lang_Object__];

The object it is operating on is an object I instantiated in the native
iPhone code using:

[[class alloc] init]

This class had a constructor initializer of a String object in the original
java code.  It was translated into the init call you see in #1 above.  The
code above in #2 is near the top of that function.

It seems that for some reason the object that I'm creating is created using
the native NSObject, and not the NSObject modified using categories by
java_lang_Object.  I'm confused as to how I could control this as the steps
I went through were pretty straight forward.

Is there some compiler option needed for implementation categories to work
correctly? (either for the library I'm creating or native application using
the library?

I think my problem must be pretty basic.

Best Regards,

Ian

Ah I see, thanks for the clarification. In this case, yes, you cannot use
that XML file with an XMLVM-generated project at the moment.

The interface builder produces an XML file which is loaded at runtime from iPhone - similar what the Android SDK does.
Unfortunately right now XMLVM does not support this XML file, since it does not produce IBOutlet and IBAction tags, neither properties.
You have to manually edit the source file yourself, but I don't know how easy this will be.

It will be better to write the GUI stuff by hand in Java; it works and you have more control over it

As XMLVM is using bytecode, you should be able to use Jython, although I

Well, nothing is stopping you from making changes to the generated code, but
if you make changed to the original code, or we introduce optimizations in
XMLVM, then you would need to re-generate your code and merging would become
necessary.

First of all, will soon deprecate the ObjC backend and switch over to the
much better C-Backend. However the answer is the same: Why would you not
write the code that sets those variables in Java as well?

So the Interface Builder spits out Objective-C Code, I imagine? You would
need to do some manual work to combine that code with the one XMLVM
generates. So far we don't have very smooth support for combining manually
writte application code with cross-compiled code.

If your JAR contains compiled classes, then you can cross-compile this with
XMLVM. Using this API from within ObjC is possible, but you would need to
know how to create and use cross-compiled XMLVM classes. Again, we don't
have easy support for merging hand-written code with cross-compiled code.


Hope that helps a bit.

Re: [xmlvm-users] Confused by error messages

[Sascha H. <sa...@xm...>]

Thanks Jeremiah for the detailed information. I guess what is happening is
that we never had such a big class to process, which is why we never hit
that limit. Is it possible to share this class with us (just send it
sa...@xm..., otherwise it will hit a size limit on the list)? Then I
will take a look to see whether we can optimize memory usage.

Thanks!

Re: [xmlvm-users] Potential supported platforms

[Markus N. <mar...@gm...>]

Hi Tomas,

So far we applied a similar approach to the one used for android2iphone. If
you take a look at http://www.xmlvm.org/android/ we finished the equivalent
of the cocoa compat-lib (at least what's needed for the demos) for the WP7.
This allows writing WP7 apps in Java using classes which mimic the native
WP7 C# API. Our next step now (actually I just started on this last week) is
to port the android compat-lib to work together with our WP7 Java layer.

We usually also reimplement the demos as native WP7 apps to get a better
idea how we can do the mapping between Android and WP7, but it's not used in
the cross-compilation.

We focused on implementing the necessary classes/attributes/methods to get
the demos to run so our implementation is far from being complete but we are
making progress. Any help is greatly appreciated and I am confident we can
find areas to cooperate in.

As far as I know my colleague already started the merge, so I hope we have
news for you soon.

Cheers,
Markus

The only automatic project creation is for iPhone projects.
So you have two ways to go on right now:

a) pretend that your application is an iPhone application (create a new project etc etc.) After creating the project go to the preferences of this project and change the SDK from iPhone to Mac SDK. You might also need to delete some files. Expect not everything to work as is, since this method is indeed optimized for iphone.

b) Manually create a new project and drag & drop these files to the new project. You still might need the files from the library.

Re: [xmlvm-users] Cross-compiling Java-classes into Objective-C

[Miggi <mig...@go...>]

Hello Panayotis

Sorry, but I'm too blind to see it. I can't find any solution for my 
problem in the documentation. The only thing that I can find is the way 
how to compile Java-classes into Objective-C and this is exactly the way 
I've done it.

Perhaps my problem was not described clear enough:
The process to cross-compile Java-classes into Objective-C-classes works 
absolutly fine. Theres no error message or something like that. But I 
don't know how to make a project out of the cross-compiled files on 
Mac-site. The result of cross-compiling the classes is a folder full of 
.m and .h-files. So can you tell me how I can get a complete project out 
of these files? And it's not an iPhone-app what I want to create, if you 
think so.

If there's a fitting part in the documentation, so I wasn't able to find 
it. So can you please give me another hint? ;)

Thank you and sorry to cause you inconvenience.

Re: [xmlvm-users] Potential supported platforms

[Tomas V. <tom...@gm...>]

Hi Markus,

That sounds interesting. Once you've submitted it I can look and see if
there is anything I can do to help.

What is your approach? Do you want to do the mapping to cross compile the
Android demos into WP7 applications or are you reimplementing the demos
using WP7 API?

Best regards,
Tomas

[xmlvm-users] Error in WebOsOutputProcess

[Mario H. <ma...@de...>]

Hi XMLVM list,

i'm playing with the JavaScript/ Qooxdoo/ WebOs backend and i finally 
managed to run a simple AWT program on a palm simulator. Any way, there 
seems to be a error in the WebOsOutputProcess during the project 
generation. The stage-assistant.js and the index.html templates are not 
found, due to wrong paths and the getResourceAsStream method.
I rewrote those 2 lines with help of UniversalFiles and attached my 
changes as patch, in case anyone is interested :o)

Greetings,
Mario

Re: [xmlvm-users] Cross-compiling Java-classes into Objective-C

[Arno P. <ar...@pu...>]

note that --target=objc only cross-compiles to Objective-C, nothing 
else. The dependent classes (such as the ones you've mentioned) will not 
be copied to the --out directory. The other targets (such as 'iphone') 
will do this.

I believe if you have a look at the documentation 
http://www.xmlvm.org/documentation/
you will be able to solve your problem.

[xmlvm-users] Cross-compiling Java-classes into Objective-C

[Miggi <mig...@go...>]

Hi there

I've some problems with cross-compiling Java-files into Objective-C. 
When I tried it, I got a .h and .m for every .class file. That's ok. But 
when I tried to build it in Xcode, I got several errors because things 
like java.lang.Object or java.lang.String couldn't be found. What did I 
wrong that such simple and basic classes weren't found?

The way I've cross-compiled the classes were:
     java -jar <path to xmlvm.jar> --in=<path to folder with java-files> 
--out=<path to an empty folder> --target=objc

Do I have to add something? Or isn't it possible to copy the resulting 
files in an empty Xcode-project and to build it?

Thanks for your answers.

Miggi

Benchmarking is a tricky business because you easily end up comparing
apples and oranges. We have not done any benchmarking. The C backend
will be much more performant than the Objective-C backend for various
reasons, but we don't know how this compares to a JVM.

But has anyone considered taking something like JavaML (http://www.badros.com/greg/JavaML/) which generates XML version of the Java program's AST (abstract syntax tree). XSL could then be used to convert this to a 'high level' target, such as C++, which is very similar to java already. Use the same GC techniques and libraries xmlvm already has - and you have maximal performance via C++ compilation of high level code rather than VM opcodes as xmlvm does today.  I would imagine several orders better performance with just as much flexibility - say write c# code for win7, and JavaScript target would be more performant as well. Java byte code is also easily reversed by libraries like JAD to generate 'high level' Java from that byte code, so .class files are still processible if code is not available.

Possible that you can do more optimizations on source code level, but
this also requires a lot more effort. E.g., there are no bytecode
instructions for generics since the Java compiler already converted
them to casts from and to java.lang.Object. This makes our life much
easier. All in all we found that by using Androids register based
instruction set (DEX) to be ideal for creating efficient code in the
target language.

Re: [xmlvm-users] problem with compiling to xcode

[Arno P. <ar...@pu...>]

I doubt that the resulting Xcode project would work on a Mac. You have
directories such as C:\ in your path that are Windows specific. As for
the ${out.dir} problem, I'm not sure. That variable should certainly
be defined. How did you compile this? With the ant run-Xcode target?
Can you verify that this also does not work on a Mac?

Re: [xmlvm-users] problem with compiling to xcode

[Marko Ž. <xm...@st...>]

Arno, thanks for the answer, but I'm not compiling it to an iPhone 
application, I'm compiling it to a xcode project, and this CAN be done 
under Windows.

So my problem is not wether I can compile it to an iPhone application or 
not, but about an error in the ant build process. To clarify it a little 
bit...
In the xcode.xml file we have a java call to the xmlvm that converts the 
application into xcode. In this call, there's an argument like this:

<arg value="--in=${out.dir}/classes"/>

The problem is that in the process of ant building the ${out.dir} is not 
resolved to its value, so I get an error message

  [java] [02/12/11 14:40:18.718]    ERROR: UniversalFileCreator: Location is neither a File nor a directory: C:\MobDev\xmlvm\trunk\xmlvm\demo\iphone\ifireworks\${out.dir}\classes


I tried to replace ${out.dir}/classes with a hardcoded path, like this:

     C:\MobDev\xmlvm\trunk\xmlvm\demo\iphone\ifireworks\build/classes

and after that it works without problem and compiles it to xcode. So it 
means that it can be done.

But this is not a sollution, rather a quickfix, and would like to know 
if there's a sollution to this ${out.dir} problem?


P.S. I have investigated a little bit, and it seems like there are ways 
to compile xcode projects on windows. So when I go past this build 
problem I plan to follow this road all the way.

You cannot compile for the iPhone under Windows. You need a Mac OS platform.

Yes, the --target=iphonec instruction I mentioned below should work. Is that

Re: [xmlvm-users] Confused by error messages

[Jeremiah B. <jbl...@da...>]

Hi Sascha (and others),

I've gotten a little further now. At this point I don't think my current
machine has enough memory to actually translate the project in question
using the current version of XMLVM, but I wanted to let you know what I
found out for future reference. It's a pretty big project and I know that
XMLVM is a work in progress, so it may just be a matter of scale. When I get
to an upgrade point, or when XMLVM is a bit more mature, I'll try again.
Anyway, here's what I've found.

It looks like one of the pre-built files - nbproject\xcode.xml - has the
setting "-Xmx512m" hard-coded in. I changed it and also added "--debug=all"
to the same file.

However, it's still running out of memory. After some testing, I went with
1350m - on my machine, anything more than that starts thrashing the hard
disk due to excessive paging. The memory for the java process goes up to
around 1500M or so according to top.

Here's an abbreviated version of the output:

-do-xproject:
     [echo] Creating Xcode project
     [java] Executing
'/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/bin/java'

Processing method: interpretCode
     [java] [02/01/11 13:15:12.901]    ERROR: Oh no, XMLVM needs more
memory. Try running with -Xmx1G.

... and following that, a lot of exception and stack trace info.

The file it gets caught on is about 100K, and the function interpretCode is
about 1000 lines long and includes a large switch statement (about 140
cases) as it is an interpreter for an instruction set.

I'm not sure if this helps narrow it down or not. I could try to come up
with a simplified code segment that still exhibits the problem, though it
may be difficult as I have to find a way to eat up a comparable amount of
memory. :)

[xmlvm-users] problem with compiling to xcode

[Marko Ž. <xm...@st...>]

I tried to compile the iphone demo applications to Xcode project but 
when executing ant build it stuck at -do-xproject and I got this error:

-do-xproject:
      [echo] Creating Xcode project
      [java] [02/12/11 14:40:18.718]    ERROR: UniversalFileCreator:

Could not find input resource: ${out.dir}/classes


It seems like it doesn't resolve the ${out.dir}reference, but why? What 
could be the problem?


P.S. I'm using Ant 1.8.2, Eclipse Pulsar edition, and the latest xmlvm 
from svn.
