Re: Confused about Inventory Items
You may be interested to read the Data Model Resource Book p.84 http://docs.ofbiz.org/display/OFBADMIN/OFBiz+Related+Books Without this book you may lose time... Jacques De : Andrew [EMAIL PROTECTED] I'm apparently missing something about the way inventory works, but hey I'm still learning. I have set up a product (Gearbox) with a few selectable features. (Make, model, quality, year) Or rather created some Feature Groups which are then attached to my Category of used parts. and Gearbox is product of that category. Now if I go my facility and receive inventory of 1 Gearbox there is no way to select what the values features are . eg make= honda, model=civic, quality=damaged, year=1990. I would have thought an inventory item (Which I now have) would have to have those features set. On I suspect a similar note I never have anything in Physical Inventory and in general have no idea what that tab is for. I expect there is just some user documentation on Facilities I haven't found that would explain all this. Thanks for any pointers. Andrew

Re: OfBiz System Configuration Wizard
Again, we use the Asset Maintenance component OOTB here. Even though I'm an in-house IT guy and I was the one who installed OFBiz here, it didn't have to be me doing it. Our facilities manager (person, not program) could have downloaded a binary release, unzipped it and started using the Asset Maintenance component on his own. No consultant or systems guru is needed. Seriously. Many of our users are at that skill level where they could download and install software themselves. The problem comes when someone like that tries to follow the Production Setup guidelines and is told to modify properties files and XML files. They won't know what to do at that point. I believe this to be a very real scenario, especially once the Accounting component is finished. A binary release doesn't have to come from the OFBiz site. It could come from another source, like Opentaps. I suppose someone providing a binary release of their own could develop their own system configuration screen as well. -Adrian Walter Vaughan wrote: Jacques Le Roux wrote: I'm not sure to see the frontier here...

Re: FastMap Vs HashMap,
I just spent some time running performance tests on FastMaps and HashMaps. Calling the get methods showed no speed difference.

Re: Currency in store and eCommerce
Hello Jacques and David, I realize that the activity on this issue is a little old, but I have a scenario that would greatly benefit from a solution or complete documentation around this issue. Just to recap, the issue was about virtual products being set in one currency and their variants set in a different currency and how to get the currency to display for the variant. David had mentioned that the currency set for the store is what determines the final currency for products. Jacques had said: So as I thought it's better to handle different currencies in different stores for now. Am I missing something here ? Is that always true ? Is it a recommended best practice to do so (having 1 store by currency) ? Are there other scenarios, future scenarios ? David said: No. The price stuff will look for prices according to the currency set on the ProductStore. and NO! Not totally correct. In this case of the ProductStore currency was USD then the virtual product's prices would be used. If the ProductStore currency was EUR, then the variant product's prices would be used. My question is about what was ultimately determined on this issue (I apologize if I am asking for a repeat of something already stated). My scenario is this: Default Currency in Store is set to USD Virtual Product ABC is set in USD Variant Product ABC-1 is set in USD Variant Product ABC-2 is set in GBP When a user selects the variant product in British pounds, is there a way to show the pricing in this currency, even if the default Currency Uom for the store is USD?? Or is the best practice to have multiple stores, each with their own currencies? I would appreciate any direction you could give me.

At this point you have to have a deeper knwoledge on business ans tech. aspects and I'm not sure the average SUgarCRM user (or such package) have such a knowledge.

Re: FastMap Vs HashMap,

JSONObject to Map

Re: FastMap Vs HashMap,
It is actually a pretty big deal, and there are very good reasons it was integrated into OFBiz. In OFBiz we deal with LOTS of temporary objects, especially Maps and Lists, and when doing performance profiling you can see the impact of this in the results (ie lots of time creating objects and allocating memory, lots of work for the garbage collector to do when destroying objects and un-allocating memory). Because of this it makes a big difference to use recycled objects like the Javolution FastMap and FastList, ie calling FastMap.newInstance() to get an object out of the pool of existing FastMap objects rather than calling new HashMap() to create a new HashMap each time. There are actually lots of performance tricks that OFBiz uses, though most of the work was done before most of the people now involved with OFBiz were around. Early on I spent a few weeks profiling and tweaking over the course of a few months as things were being heavily developed. Our classpath caching, special purpose internal methods in the entity engine, and the use of Javolution for the Fast* objects and for object recycling for often used but short-lived things like the GenericValue object (which is a recycled object) are all results of that effort. For other things like get and put operations on a FastMap versus a HashMap... I wouldn't expect a whole lot of difference. It may be that FastMap does a better job of managing large and scattered hash arrays or something but there is really only so much you can do with that as those algorithms have been around for a LONG time and have been thoroughly reviewed and refined by lots of people. To really get an understanding of this would require a bit of research, but it's all very standard computer science stuff, so the material is readily available and very accessible if you get a decent book or whatever. It is nice stuff to know about because these basic data structures and algorithms are what everything is based on in modern software and understanding them makes it way easier to understand performance impact and interpret the results of profiling, as well as understand higher level algorithms and data structures like those used in relational databases and such. Knowing all of that stuff is of course not a substitution for using a profiling tool, and in fact those who really understand the stuff know all the more how important it is to use profiling tools. The nature of the software is that it is very complex, and even if you know it all it's hard to remember and grok the importance of certain pieces sometimes. In other words it's deterministic, but complex. The most experienced people will know that they might be able to guess really well and understand really well the general things that might impact performance, but until you do profiling and tweaking to see a performance difference they are only guesses and guesses aren't proofs, and aren't enough if you're trying to be careful and make a real difference in something. In short, doing profiling is great and extremely valuable, as is understanding the underlying data structures and algorithms. However, neither of them along is sufficient to really understand and describe why something is performing a certain way or make a difference in how it performs. -David On Dec 14, 2007, at 1:28 PM, Jacques Le Roux wrote: Sumit, Adrian, All, I had a cursory look at it.

Early on I spent a few weeks profiling and tweaking over the course of a few months as things were being heavily developed. Our classpath caching, special purpose internal methods in the entity engine, and the use of Javolution for the Fast* objects and for object recycling for often used but short-lived things like the GenericValue object (which is a recycled object) are all results of that effort. For other things like get and put operations on a FastMap versus a HashMap... I wouldn't expect a whole lot of difference. It may be that FastMap does a better job of managing large and scattered hash arrays or something but there is really only so much you can do with that as those algorithms have been around for a LONG time and have been thoroughly reviewed and refined by lots of people. To really get an understanding of this would require a bit of research, but it's all very standard computer science stuff, so the material is readily available and very accessible if you get a decent book or whatever. It is nice stuff to know about because these basic data structures and algorithms are what everything is based on in modern software and understanding them makes it way easier to understand performance impact and interpret the results of profiling, as well as understand higher level algorithms and data structures like those used in relational databases and such. Knowing all of that stuff is of course not a substitution for using a profiling tool, and in fact those who really understand the stuff know all the more how important it is to use profiling tools. The nature of the software is that it is very complex, and even if you know it all it's hard to remember and grok the importance of certain pieces sometimes. In other words it's deterministic, but complex. The most experienced people will know that they might be able to guess really well and understand really well the general things that might impact performance, but until you do profiling and tweaking to see a performance difference they are only guesses and guesses aren't proofs, and aren't enough if you're trying to be careful and make a real difference in something. In short, doing profiling is great and extremely valuable, as is understanding the underlying data structures and algorithms. However, neither of them along is sufficient to really understand and describe why something is performing a certain way or make a difference in how it performs. -David On Dec 14, 2007, at 1:28 PM, Jacques Le Roux wrote: Sumit, Adrian, All, I had a cursory look at it. In abstract, yes this seems to be right Though those lines you took from Google are 4 years old http://www.javalobby.org/java/forums/t9377.html?start=15#reply20 Anyway it seems to be right, here the answer from Javolution Creator (JM Dautelle) The best analogy between FastMap and HashMap would be buying versus renting. With FastMap you pay upfront but you are done with it. With HashMap you pay each time you put a new entry (not only when you allocate but also later with the GC interests...). Obviously if you intend to sell your house three months later it does not make sense to buy it. Also interesting is JM Dautelle's this note found at http://javolution.org/doc/benchmark.html Although it looks nice, I see that some of your collection classes are not always faster than their Java 6 counterparts.

Re: Confused about Inventory Items
Hi Andrew, Have you created a single product for the Gearbox, i.e. only one entry in the Product entity for the product Gearbox, and trying to apply all the selectable features to this particular product? If yes, than your data is still not complete. :) Here is something that I know about creating a Product with more than one selectable features. 1) The first thing to note down is, a product with selectable features means a product with variations, that means this product can have different variations depending upon its selectable features. Each set of selectable features defines one variation of that product. So we can say, suppose for buying purpose, that a customer won't buy the product itself, but its varients. 2) Above explaination leads to the point that for a product with selectable features, you need to create: a) A Virtual Parent Product (for which no physical inventory exists and hence can't be purchased) b) One Varient Product for each set of selectable features, so this gives a whole bunch of products to you. (Physical Inventory will exist and will be the actual purchasable products). 3) Create ProductAssoc(s) for Virtual Parent Product and its Varient Products. 4) You need to define a ProductFeatureCategory for your Product. 5) Prepare seed data for ProductFeatureType for make, model, quality etc. if not present in OFBiz seed data. 6) Create ProductFeature records for the selectable features of each type. 7) Associate ProductFeature(s) to the Virtual Parent Product as SELECTABLE_FEATURES in ProductFeatureAppl. 8) Associate each Varient Product to the set of ProductFeature it corresponds to as STANDARD_FEATURES in ProductFeatureAppl. I think that is all we need to do to create a product with selectable features. For an example of creating such products in OFBiz, you can refer to ofbiz-trunkapplicationsecommercedataDemoProduct.xml. And finally I think this should answer your question about inventory. The Inventory you receive will be for the varient products, which are the actual physical products, each varient reqresenting a set of selectable features and not for the Virtual Parent Product. Actually you are not supposed to select features while receiving Inventory, instead you will receive the required varient for the set of required selectable features.

I have set up a product (Gearbox) with a few selectable features. (Make, model, quality, year) Or rather created some Feature Groups which are then attached to my Category of used parts. and Gearbox is product of that category. Now if I go my facility and receive inventory of 1 Gearbox there is no way to select what the values features are . eg make= honda, model=civic, quality=damaged, year=1990. I would have thought an inventory item (Which I now have) would have to have those features set. On I suspect a similar note I never have anything in Physical Inventory and in general have no idea what that tab is for. I expect there is just some user documentation on Facilities I haven't found that would explain all this. Thanks for any pointers. Andrew Be a better friend, newshound, and know-it-all with Yahoo!

Re: Party Information
Hi Brendan, We can create Party for any person or group. A person is for a single person and a Group is for any organization or a departments in an organization. We can assign roles (more than one) to each person according to the roles they play in a organization (like employee, customer, vendor etc.). We can also create PartyRelationships to represent the relation between different persons, groups and person to group. We can also upload Contents for a Party(person). We can create UserLogin for each person and associate it to a SecurityGroup to give him required access permissions to the System. There are many more functions available for a Party that can be used according to individual's purpose.

Every one that works for me is going to use the system, so is he/she a person or an employee. If there is anything like this please let me know. I am trying to learn as much as possible about the OFBiz system but by bit.
