JavaLoader
Locked
 
|
Hi,
I saw this repository on smalltalkhub: http://smalltalkhub.com/#!/~blabux/JavaLoader/ and I wonder if someone could give me some examples of use. For example, is it possible to use JavaLoader with Roassal to display class hierarchy of a java project or something like that? I browsed google and the mailing list's archives but didn't found any doc/examples... Maybe I'm not searching in the right place? :) Thanks in advance, Julien |

Hi Julien,
You should have a look at the Moose platform: http://moosetechnology.org Moose is made exactly to analyze software, and has more then 15 years of engineering. Roassal is a component of Moose. To analyze some Java, you need a tool to translate your .java files into a big .mse file. MSE is a meta-model that is accepted by Moose. As far as I know, two tools are available for this: VerveineJ and inFamoos(? I cannot remember the exact name). VerveineJ is unfortunately not free. Ask directly in the Moose mailing list for this. However, I have a copy of it. I can generate the .MSE file if you give me access to the Java code. Cheers, Alexandre

Hello, I'm the developer of that library. I have some tests that should shed some light. If you ned any help, just ping me. I try to keep it update with the latest Pharo releases. But, I haven't used it in a long time because I originally developed it to load in Java serialized streams and to read in Java class files. Let me know if you need anything.

Thanks for providing this lib :)
Is it compatible with only a certain version of Java? On 26/03/15 16:02, Blaine Buxton wrote: > Hello, > I'm the developer of that library. I have some tests that should shed some > light.

Hi Blaine,
Can you tell us more about it. What is the current stage of it? It looks like highly promising. But it is a significant task to reach a usable state I imagine. Cheers, Alexandre

It should work. It's something that I did several years ago around Java3. I've made sure it has worked with every Pharo release (the tests pass under Pharo3). I will look into why they are failing under pharo4. It's a project I did because I was mainly doing Java and go frustrated with serialization errors and it just went from there. The classloader and decompiler were for my own edification. I used to have it working inside the inspectors in Squeak, but I doubt they work now. I've been meaning to work on it again. Everything should work. I did start on being able to Java VM code inside of Pharo, but got sidetracked with work and life. I'd be happy to talk more. It's been about a year since I last looked at the code. I'll dig around sometime soon. On Thu, Mar 26, 2015 at 1:21 PM, Alexandre Bergel <[hidden email]> wrote:

Oh Java 3 I guess that's why there is an error when I try to load my
Java 7 bytecode. It told me there is an error because of "<" symbol. I guess Java 3 didn't supports generics? (The first version of Java I used is Java 6 so i don't know.) Is there a way to update this package easily to be used with java 7 or even 8? I can try to help but I don't know if I have enough knowledges on java bytecode to help here.

I updated the java loader library to Pharo 4 (load the latest from smalltalkhub.com). There was a few bugs and deprecated methods, but I fixed them all. I loaded a new Java 8 class (with lambdas) and everything is working. If you have a problem, could you send me the offending class to [hidden email]? There's a lot of moving parts and I would like to start adding tests for what fails.

Ok I will do another test and if it fail again, I'll sent you the file.
But not now cause I'm a bit busy this week-end. Maybe next week. Thanks for updating your project.
