Objective-C Java Bridge


  • Subject: Objective-C Java Bridge

I am building and application that makes extensive use of webservices. The webservice return many complex objects and I have found that the Webservices tools on Panther are somewhat lacking in that they cannot parse Schemas to create objective-C model objects. That been said, I have decided to investigate moving my object model to Java but using Objective-C for UI stuff. This way I can leverage the rich webservices / XML API's that are available for Java. My initial tests using the Apache Axis webservices API have been very fruitful (our JBoss application server uses Apache Axis also). Now on to my question : This particular architecture makes extensive use of the Objective-C Java Bridge, I have not been able to find articles or a whole lot of documentation on it's use. Does anyone on the list have extensive experience using the ObjC-Java-Bridge and if so are there any caveats or big gotcha that I should be looking out for (besides a bigger memory footprint, performance hit) ? The bridge is so easy to use that I am somewhat frightened :)

Also, does anyone knows what the following warning mean when instantiating the JVM :

Java HotSpot(TM) Client VM warning: Attempt to protect stack guard pages failed.
Java HotSpot(TM) Client VM warning: Attempt to deallocate stack guard pages failed.
