Example 1 with ByteArrayClassPath

use of javassist.ByteArrayClassPath in project motech by motech.

the class MDSConstructorImpl method buildInterfaces.

private void buildInterfaces(JavassistLoader loader, MdsJDOEnhancer enhancer, EntityDto entity) {
    List<ClassData> interfaces = new LinkedList<>();
    if (entity.isDDE()) {
        Bundle declaringBundle = MdsBundleHelper.searchForBundle(bundleContext, entity);

                        interfaces.add(new ClassData(interfaceClass.getName(), IOUtils.toByteArray(in), true));
                    }
                }
            }

            LOGGER.error("Class {} not found in {} bundle", entity.getClassName(), declaringBundle.getSymbolicName());
        } catch (IOException ioExc) {
            LOGGER.error("Could not load interface for {} class", entity.getClassName());

    for (ClassData data : interfaces) {
        try {
            MDSClassLoader.getInstance().loadClass(data.getClassName());
        } catch (ClassNotFoundException e) {
            // interfaces should be defined in the MDS class loader only if it does not exist
            MDSClassLoader.getInstance().safeDefineClass(data.getClassName(), data.getBytecode());
            ByteArrayClassPath classPath = new ByteArrayClassPath(data.getClassName(), data.getBytecode());
            MotechClassPool.getDefault().appendClassPath(classPath);
            MotechClassPool.registerEnhancedClassData(data);
            addClassData(loader, enhancer, data);

    ClassData data = enumBuilder.build(holder);
    ByteArrayClassPath classPath = new ByteArrayClassPath(data.getClassName(), data.getBytecode());
    MotechClassPool.getDefault().appendClassPath(classPath);
    MotechClassPool.registerEnhancedClassData(data);
    // register with the classloader so that we avoid issues with the persistence manager

    addClassData(loader, enhancer, data);
}

Example 3 with ByteArrayClassPath
