Adding a category to an asset in a custom policy

Hello

I need to create a custom policy that will add a category to an asset. I've been digging through the Java API and think I have a good approach, but it is not working. My code looks like this...

CategorySchema newCategorySchema = myAsset.getAvailableCategorySchema("Service Usage Indicator");

Category newCategory = newCategorySchema.getCategory("Service Usage");

SubCategory newSubCategory = newCategory.getSubCategory("First Use");

SubCategory[] subCategories1 = {newSubCategory};

newCategory.setSubCategories(subCategories1);

Category[] categories1 = {newCategory};

newCategorySchema.setCategories(categories1);

CategorySchema[] schemas1 = {newCategorySchema};

myAsset.setCategorySchemas(schemas1);

However, this gives me an exception...

exception java.lang.NullPointerException stack trace=[com.ibm.ram.client.RAMCategorySchema.setDirty(RAMCategorySchema.java:411), com.ibm.ram.client.RAMCategory.setDirty(RAMCategory.java:415), com.ibm.ram.client.RAMSubCategory.setDirty(RAMSubCategory.java:432), com.ibm.ram.client.RAMSubCategory.setSubCategories(RAMSubCategory.java:706), com.ibm.ram.client.RAMCategory.setSubCategories(RAMCategory.java:474), ......

What is the correct way to categorize an asset via a custom policy? I've tried many variations of the above, but keep hitting exceptions of one kind or another.

Thanks for any help!

Well, I was making this harder than it needed to be. Plus i skipped over the part of the documentation that actually answered by question!

From the IBM documentation found here >

Extending Product Function > Extending Rational Asset Manager > Using Rational Asset Manager Java API > Work with assets > Create, modify, or delete assets > Categorize an asset

//Categorize using the category schema fetched from the session

CategorySchema automobilesSchema =

session.getCategorySchema("Automobiles");

Category priceCategory = automobilesSchema.getCategory("Price");

newAsset.categorize(priceCategory, "25000");

//Categorize using a category fetched through the asset

automobilesSchema = newAsset.getAvailableCategorySchema("Automobiles");

Category colorCategory = automobilesSchema.getCategory("Color");

newAsset.categorize(colorCategory, "Red");

//Categorize using sub category objects

Category modelCategory = automobilesSchema.getCategory("Model");

SubCategory domestic = modelCategory.getSubCategory("Domestic");

SubCategory foreign = modelCategory.getSubCategory("Foreign");

SubCategory honda = foreign.getSubCategory("Honda");

SubCategory camry = foreign.getSubCategory("Toyota/Camry");

newAsset.categorize(domestic);

newAsset.categorize(honda);

newAsset.categorize(camry);

session.put(newAsset, new NullProgressMonitor());

getSubCategory("SubCategory-Name"); this method does not work when the input argument "sub-category-name" has backslash(/).

E.g: getSubCategory("sub/category") --> returns null

Please let me know if there is any workaround for this. I tried to eescape it by placing \ before /, but did not work.
