Hello Michael. Indeed XMLVM is not as active as it used to be. On the plus side, there is a new project that tries to fill up the gap and uses XMLVM for this purpose. Disclaimer: I am the core author of this project. The project is CrossMobile and can be found here: https://github.com/crossmob/CrossMobile It is developed for more than 5 years and recently was fully released as an Open Source project. With CrossMobile you can create native iOS, Android and Desktop applications. And is not only capable of reusing some Java logic into Objective C, but also all kinds of beautiful stuff, starting from GUI and extending to things like push notifications, maps, geolocation etc. Since we are doing our baby steps in the open source world, we’d be happy to hear any kind of feedback and how to become even better. For more information you could also check https://crossmobile.tech/ Panayotis On 12 May 2019, 05:12 +0300, Michael Gough <inn...@gm...>, wrote: > > Hi I was very pleased to learn about XMLVM's existence.

Hi I was very pleased to learn about XMLVM's existence. I was disappointed to see that it seems like it became inactive 5 years ago. I have learned today that it is once again active. I would like to ask the list what the current status is. Is XMLVM in a usable state with objective C as a target language? My interest is in translating some business logic classes that perform no IO. Thanks Michael Gough |

Hello Sir/Madam We are a very small organisation in India and we have a Project management Product in iOS/Mac/Windows/Android .The thing is we need to read .mpp file from our iOS App and for that there is a library called MPXJ( http://mpxj.sourceforge.net/) which is in Java. What we are trying to do is converting this above mentioned library into Objective C/C so that we can import that library into our Xcode project . I am just going through your site you guys are also doing the same but some how the developers are not able to do that using XMLVM. Could you please help us with your valuable guidance. If you guys can convert it for us we can arrange a commercial deal with you. Please let me know if that is possible . Awaiting for your response.

Arno is right, J2ObjC is the only project designed to answer your use case of porting a library and not the whole application. We used to use XMLVM for the Codename One iOS port and eventually migrated to our own VM which is open source and far simpler/smaller than the solutions mentioned above despite including a concurrent GC builtin. If you are thinking of taking a different route then Codename One is the only solution that has true WORA support. Best Regards, Shai. [image: Codename One Logo] <http://www.codenameone.com/>Codename One allows Java developers to build native iOS, Android & Windows Phone applications using the cloud/private cloud.

Hi, another alternative is the Intel Multi-OS Engine: https://software.intel.com/en-us/multi-os-engine It is based on the ART runtime from Android, and has a much better price (free) compared to RoboVM. Disclaimer: Intel acquired our product Migeran for iOS ( http://www.migeran.com/migeran-for-ios/) and it is now part of the Intel Multi-OS Engine. If you have an Android app, and you want to port it to iOS, you can also use our Migeran Analyzer (free service) to check how much work it would take to port it to iOS with the Multi-OS Engine.

Maybe beside j2objc you might want to have a look at robovm, which is afaik a llvm-based translator from java=>objc https://robovm.com/ Oh,..seems it isn't free anymore. But I know the libgdx-guys use it to 'crosscompile' games made with libgdx to objc (or at least iOS-compatible stuff) Might be worth a look... Have fun.

active development on XMLVM stopped a couple of years ago, so the simple answer to your question is "no". You can stop reading here but for your benefit let me answer your other questions: 1. no 2. the current version of XMLVM can translate any Java byte code to C (there is also an older Objective-C backend). For the runtime library it uses Apache Harmony. 3. The C backend of XMLVM supports basic reflection. You can dynamically invoke method and inspect classes. However, since there is no class loader, you cannot do things like injection. 4. XMLVM bundles a garbage collector with the generated C code. To my knowledge, J2ObjC still relies on reference counting and one has to be more careful with memory management. However, J2ObjC is under active development so that is the way to go.

Hey, I’m looking into XMLVM and had some questions. So I’m looking to translate a Java based library with non-android specific code to Objective C so the code can be used on iOS. Again the library is platform agnostic. 1. Is XMLVM production ready for a task like this? 2. Are there any limitations on the code it can translate? 3. How does XMLVM respond to reflection? 4. Are there any advantages for something like XMLVM over J2ObjC? Thanks, Scott |

Hi Sam, the information for how to contribute is here: https://sites.google.com/a/xmlvm.org/documentation/developing-xmlvm/ This should show up on our website under "contribute" but is currently broken, appologies for that, we'll get that fixed.

Hey Arno, I use XMLVM as the backend of a cross-platform mobile game framework (the “AbsurdEngine”). I have a fork that implements some functions in native_java_net_InetAddress.c (giving Android-to-iOS HTTP support) and adds some methods missing from the Android graphics compatibility libraries. I’d love to contribute these and any other changes I make 😊 what is the process for submitting?

I supponse that TrayIcon class is missing.
In what Java version must the code to be written? Java 6? Java 5?
When will be released the first stable version of XMLVM?
Thank you very much!

Thanks for all of the replies on this. I have succeeded in knocking rebuild times down to under 10 seconds in some cases, 20 seconds in most cases and 45 seconds in almost all cases. The strategy I used was to: 1. Compile everything using the "vtable" target, and store in a cached directory. 2. Compile everything to c (using whatever target I plan to use... in my case I'm generating the iphone xcode project). 3. On rebuilds, I compare modification times of java source files with the corresponding c header files in the destination build directory. I only recompile the changed files with javac. 4. I build a dependency tree starting with the changed files to produce a set of "dirty" files (e.g. files that might have to be changed due to the changes to the changed files). 5. I convert the set of dirty .class files to c files using XMLVM (using the "c" target). This doesn't pull in any of the dependencies, but it does generate warnings when classes vtables can't be found. 6. Remove the dependency on the constant pool for the converted c files. This was fairly easy to do via regex. 7. Fix vtable errors in the converted c files. This involves some crude static analysis of the c source files (and I can make use of the cached c source from the initial builds). 8. Copy the resulting c source files into the final build directory. 9. Run the project in Xcode. It will only need to recompile the changed source files, so this is very fast. If I'm making changes to a java class that uses other classes, but isn't itself used by any other classes, then the set of dirty files will only be that one file. If I'm working on a class that is used by a lot of other classes, of course this will result in more classes requiring recompile. But unless I'm making changes to java.lang.Object (which I shouldn't be) the dirty set is still usually pretty reasonable. Right now the source code is a bit of a mess because it was the result of a lot of experimentation, and it is geared toward my particular use case but I will be placing it on Github once I've cleaned it up a bit.

some quick comments from my side: XMLVM performs a static analysis of the Java classes needed for an application. This also determines which methods will need to be called via a vtable (for the C backend). If the application changes, this might have impact on the way the base class is generated (e.g., if the way a base class method is called changes). For the same reason the itable (interface jump table) and constant pool can potentially change between builds. It would be possible to significantly speed up compilation times if one were to generate a library that contains a cross-compiled version of all JRE classes. This would also require to disable the vtable/itable/constant pool optimizations. No static analysis would be necessary and the only classes to be cross-compiled would be the application itself. While this is possible, this is also *a lot* of work. This changes the whole build process and also requires changes to the generated Xcode project. Paul Poley suggested a way of using rsync to copy only files that have changed between builds. This will not speed up XMLVM but at least the following Xcode build. You can find his suggestion somewhere in the archives of this list. Another quick comment about the --target=xmlvm: this was never fully implemented. You can generate .xmlvm but there is no frontend (or InputProcess in XMLVM terms) to read these .xmlvm files. Sorry to be the bearer of bad news but there is no simple solution.

Thanks for the reply. I don't think static libraries on their own will get me where I need to go. Have you created static libraries with the c output of xmlvm? As far as I can tell there are a few aspects that won't work nicely with this . eg constant pools. Currently the compile time from java source to running on the iOS simulator can be upwards of 10 minutes. Even if a few java files are changed most of the c files need to be regenerated. My goal is to get recompilation to under 10 seconds. I've looked at the problem for a while and believe I can do this. The xmlvm format was my first choice for an intermediate format because of the ease of transforming XML. But I can work with java source files also if this won't work. Static libraries may possible as a byproduct of what I will be doing but I don't think they are a solution in themselves.

I believe the answer to your problem should be to create a static library instead. This article might be of help - at least it is the only one that I followed for my own projects and worked. http://www.raywenderlich.com/41377/creating-a-static-library-in-ios-tutorial On March 11, 2014 at 2:17:21 AM, Steve Hannah (st...@we...) wrote: > I just want to check if this is supposed to be possible. > > Suppose I have a folder with .class files named "java-src". > > I run > xmlvm --in=java-src --out=xmlvm-src --target=xmlvm > > Then at a later time > > xmlvm --in=xmlvm-src --out=c-src --target=posix > or > xmlvm --in=xmlvm-src --out=c-src --target=c > > etc.. > > Is this supposed to be possible? > > I'm working on improving build times by introducing some caching and > eliminating inter-class dependencies.

I just want to check if this is supposed to be possible. Suppose I have a folder with .class files named "java-src". I run xmlvm --in=java-src --out=xmlvm-src --target=xmlvm Then at a later time xmlvm --in=xmlvm-src --out=c-src --target=posix or xmlvm --in=xmlvm-src --out=c-src --target=c etc.. Is this supposed to be possible? I'm working on improving build times by introducing some caching and eliminating inter-class dependencies. My first idea was to generate .xmlvm files as an intermediate representation to treat as a cache. However I am having difficulty generating anything from .xmlvm files. If this is supposed to be possible, I can provide stack traces etc... If not, I'll proceed to attempt different strategies. Best regards Steve |

I am trying to set up some caching during compiling java to c. I have set up a build process that detects which java source files have been changed since their .c or .h files were generated. Ideally I would then like to compile those changed files with javac and pass them through xmlvm. There are a couple of issues to overcome in this. 1. Constant pools. I can handle this. 2. Vtables for classes that have been previously converted and haven't changed. Since these aren't included in the batch of files to convert, xmlvm knows nothing about them. Is there a way to load vtable info for classes that aren't being converted so that they can be referenced by xmlvm? I guess I'm looking for the equivalent of a class path for xmlvm. I'm assuming this is not currently supported. Can you recommend a starting place in the api where I should start looking for adding this? I just need to be able to load some vtable data into xmlvm programmatically. Thanks for any tips. Steve |
