bug=47357 a=edburns r=ashuk This change creates a new directory, java/webclient/src_share, that contains the code that will be used in both src_moz and src_ie, and any other native browser wrapping implementations. Here are the steps I followed to implement this change. 1. Create a new directory java/webclient/src_share 2. Move all jni_util*.* files from src_moz into src_share 3. Make it so src_share compiles into a new .lib src_share has no netscape dependencies. Any functionality that depended on ns dependencies was kept in src_moz. In this case, we have a function prototype only in src_share, with the implementation in src_moz. We did this for nsHashtable. The other trick was for things in WebShellInitContext that had nothing to do with Netscape. This case was accomodated by creating a new struct, ShareInitContext, that contains all WebShellInitContext members that have nothing to do with Netscape. Currently this is just jobject propertiesClass. I modified the WebShellInitContext struct to contain a ShareContext struct as its last member. There are two new methods in jni_util.h that allow for the initialization and deallocation of the members of the ShareContext struct. 4. Make it so src_moz uses the new .lib to provide the jni_util behavior a. Create ns_util* files that include ../src_share/jni_util* files appropriately. The only tricky part was for things in jni_util.h that Here's the list of files in this change. cvs -z3 -n update (in directory D:\Projects\mozilla\java\webclient) cvs server: Updating .
