Re: JavaMail Props Not Being Set
On Jun 26, 2006, at 7:26 AM, Drew Thoeni wrote:
I am trying to set the SMTP host for JavaMail. I have attempted set

In the Application() using this code:
public Application() {

props.put( mail.smtp.host, smtp.comcast.net );

Drew,
You code only changes the values inside the props object that you
got back as a result of the System.getProperties() call. You need to
set them back into the system by using the System.setProperties
( Properties ) call, or two calls to System.setProperty( String,
String ).
Alternatively, you can specify the properties outside of the code in
two places. First, in the Properties file that is located inside
the .woa bundle at MyApp.woa/Contents/Resources/Properties, you can
put the lines:
WOSMTPHost=smtp.comcast.net
mail.smtp.host=smtp.comcast.net
just as written and they will set the WOSMTPHost and mail.smtp.host
properties for the application. Alternatively, you can launch the
application with the arguments:
-DWOSMTPHost=smtp.comcast.net -Dmail.smtp.host=smtp.comcast.net
in addition to any other launch arguments and the properties will be
set. Note that there is no space between the -D and the property
name, and that any characters that will cause problems for the shell
will need to be escaped or quoted.
In general, setting properties through code is discouraged -- much
better to do it from the Properties file for properties that don't
change frequently and from launch arguments for those that do change
frequently. BTW, property values specified on the command line
override those specified in the Properties file. See the WO API docs
on NSProperties for more details.

Re: Fast tree scan
Flor, Two things spring to mind. The first is to just have the entity cached in RAM via the setting in EOModeler. Select the entity, inspect it, and go to the advanced entity inspector (the second icon), and select the checkbox at the bottom that says, Cache in Memory. This will pull in all of the snapshots for the entity, and then when you traverse the tree the EO's are generated from the cached snapshots and you avoid the round trip to the database. This works best if you are going to traverse all of the trees and there aren't so many individual EO's that you start running out of RAM. The second technique is to set a prefetching key path. This is made really easy because you already have a single separate root object that has a to-many relationship to all of the nodes of a particular tree. Fetch that root node, but in the fetch specification set a prefetching key path that follows the to-many relationship and gets all of the nodes into memory in one round-trip to the database. This works best if you are going to traverse only one or a few of many trees, or if there are so many nodes that you can't cache them all in memory. Hope this helps. --Paul Paul Suh http://www.ps-enable.com/ [EMAIL PROTECTED] (301) 643-1516 On May 31, 2006, at 11:21 AM, Florijan Stamenkovic wrote: Hi all, I have an entity that relates to itself, having a parent and children of the same entity. It works fine. The intention is that the tree can be used to indefinite depth, with an indefinite amount of branches. Practically, this measures let's say ten levels of depth, and involved hundreds of nodes. And there can be quite a number of trees managed. At one point however I need to scan the whole tree. That takes a while because of EOF faulting, where children are not resolved until they are asked for. Since this is used in a Java Client scenario, that means that the children for every node cause a trip to the application server to get the data. It is immensely cheaper to get it all in one. My solution was to relate every node to the root node, which is of a different entity. That way all the nodes belonging to the same tree can be resolved through one request, regardless of how deep they are. This however does not help me, because still the children for every node are faults, and still a round trip is made when I resolve them. So, the question is: does anybody know how this can this be optimized, so that I don't have to have so many round trips? TIA, Flor ___ Do not post admin requests to the list. They will be ignored.

Re: generating response in different thread
Christian,
The problem that you're running into is that when you access a EO's
values you're supposed to lock the EO's editing context first. The
session's default editing context is locked and unlocked for you as
part of the request-response loop, but if you're trying to access the
EO's in another thread you're going to run into stalls while the
thread waits for the EC lock. You're going to need to create a local
editing context in your long response page and bring the necessary
objects into it by using EOUtilities.localInstanceOfObject(...). You
can then safely lock your local EC and bind to those objects in the
long response page's thread.
A question that occurs to me is why are the bindings so slow? Is it
because you are following many relationships and firing many faults,
each of which is making a round trip to the database? If so, you
might want to look at attaching prefetching key paths to your
original fetch spec, so that you get all of the necessary snapshots
into memory in one round trip to the database -- in which case firing
the faults is lightning quick and does not require a round trip. I
have had a page go from taking over 5 minutes to generate to under a
second by putting in some prefetching key paths; instead of several
hundred transactions to the database it took only one.
Hope this helps.

Re: Too Many Sessions Are Being Generated
Jon, WOImage is definitely not the culprit. A couple of other places to look: 1) Do you have anything bound to a key in the session? Use a tool like grep to search for session in all of the .wod files in your application. 2) Are you calling a method anywhere in your code that calls session()? Another thing to try: put a log statement in the constructor of *every* WOComponent that you have in your project. Now access your app via the direct action, and see which components are instantiated. Go over those components with a fine-toothed comb to see where a session is being created.

Re: Too Many Sessions Are Being Generated
Jon, The problem is probably not in the use of the shared EC, but in the page that you are generating. If you have *any* component actions on the page then it will automatically generate a Session object to keep track of the component actions, even if you are getting to the page via a direct action. Beware that component actions may be embedded in subcomponents (e.g. a standard navigation bar that you use on all pages) and may not be immediately obvious.

Re: How to selectively save EO
Louis, If I understand your problem correctly, you would like to put in an audit trail whenever a user opens an EO for editing, and again once the EO is actually changed, right? In that case, you can trigger a save to the object graph before the user ever sees the page. The sequence of actions is: 1) User selects which EO he wishes to edit. 2) As a part of the action method, you insert an audit EO into the user's EC, relate it to the EO that is to be edited, then save the EC. 3) Return an edit page to the user with the EO to be edited in a page- level editing context. As a part of instantiating the edit page, insert another audit trail EO, indicating that the object has been edited. 4) If the user hits save, then both the EO to be edited and the audit trail EO that marks the edit will be saved. If the user hits cancel, then all of the changes in the page-level editing context are thrown away, which is exactly the desired behavior. In either case, there is an audit trail EO saved to the DB that marks that there was an edit attempt. You can do similar things if a user wants to create a new EO or delete an EO. Does this make sense? By the way, it's not so much a newbie question as an intermediate- level question. It is getting into the whole concept of multiple editing contexts and how to save changes cleanly. --Paul Paul Suh http://www.ps-enable.com/ [EMAIL PROTECTED] (301) 643-1516 On Apr 23, 2006, at 7:03 PM, Louis Demers wrote: At 3:22 PM -0400 2006/04/21, Paul Suh wrote: Louis, Trying to save a single EO while leaving others unsaved is almost always indicative of a problem in your application's design That was my initial concern and the reason I asked the question on how to do it, knowing I would be corrected by this list if that was a NONO 8-), I was worried that my design was flawed because it motivated me to do this.

Re: Transferring data
Randy, What you're thinking of is the old eoutil tool. It's still there, just hidden a bit and turned into a Java application. Open a terminal window and execute /System/Library/WebObjects/JavaApplications/ javaeoutil.woa/javaeoutil -- at first it will look like a typical WO app is launching, then it will print out usage information. For moving data in and out of databases, the typical usage is two steps -- one to dump the data out to a plist file, one to read the plist into a new DB. The nice thing is that as long as the EOModels are set up correctly, this is a great way to move small amounts of data between databases. (The tool is limited by RAM, as it essentially reads in the entire database and turns it into raw rows before pumping it out.) Typical usage is: ./javaeoutil dump /path/to/mymodel1.eomodeld -source database -dest plist /path/to/outputfile.plist ./javaeoutil dump /path/to/mymodel2.eomodeld -source plist /path/to/ outputfile.plist -dest database Your database connection information will be specified in the two EOModel files.

Re: How to selectively save EO
Ondra, This is a situation that cries out for nested and peer editing contexts. Each Volume should have its own peer EC. Each Page then has an EC whose object store is the Volume's EC. Remember that different EC's can each have their own copy of the same EO, each of which has the same EOGlobalID and refers to the same database, but which are different instances. You always build relationships between EO's within the same EC, such as connecting up an Ad to a ColorSpace. If the objects are in different EC's then use EOUtilities.localInstanceOfObject() to get an instance of the EO that is in the right EC. Be careful in your EOModel design so that you have accounted for all of the places where you really need a many-to- many relationship. When a user saves a Page object, the Page's EC flushes changes to its parent, the Volume's EC. When the user is satisfied with the entire Volume, he or she hits save and the Volume's EC flushes to the database. I hope I'm making this clearer for you, not murkier. --Paul Paul Suh http://www.ps-enable.com/ [EMAIL PROTECTED] (301) 643-1516 On Apr 21, 2006, at 3:53 PM, Ondra Cada wrote: Paul, On 21.4.2006, at 21:22, Paul Suh wrote: You should probably go back and re-think your design, so that you are no longer trying to save the single EO -- instead, your natural flow will be to save the entire state of the object graph tracked by the EC. My archetypal wanna-save-part-of-graph situation is a simulated document-like environment. For example, one of my projects allows the user to edit a number of volumes (they contain pages, and the user places ads and articles to the pages). All the information is stored in one central database, and there are relationships which intertwine all the objects into a network without clean-cut bounds (for example, all pages and also ads link to the same list of colour spaces; the user who can edit different parts of the network has its own entity, too, and there are relationships between users and objects of all kinds they are editing, and so forth). Now, the user assumes that (a) he can open more volumes at once, (b) he can save changes made inside each of them independent on the others. Possibly I am overlooking something very obvious, but I do not see a general, clean, and easy solution: either I use one EC, in which case I cannot save separately (without some real hackery :)), or I use more EC's, but then there are relationships which cross the EC boundaries.

Re: Using compound primary keys with WebObjects?
Peter, On Apr 17, 2006, at 3:07 PM, peter Burnes [EMAIL PROTECTED] wrote: While I do use automated primary key generation, I inherited a few tables that are join tables where the primary keys are compounded. It seems like from reading the Apple docs and even seeing the propagate primary key option in EOModeler, that is there is support for this concept. I am just interested if there are those out there that have used propagate primary key/compound keys or even custom-generated primary keys in real-world WebObjects applications? I know I could try to convince the DBA to redesign the data model, but at this point trying to see if WebObjects can handle this legacy application or if I proceed, with trying a WebObjects solution, that I will be heading for pitfalls without using the WebObjects way. Compound primary keys for join tables are a special case in EOF. They are automatically recognized and the primary keys from the two joined EO's are propagated to the join table. It should just work -- and usually does in my experience. --Paul Paul Suh http://www.ps-enable.com/ [EMAIL PROTECTED] enable.com (301) 643-1516 ___ Do not post admin requests to the list.
