WebObjects 5.3 and J2SE 5.0
Title: WebObjects 5.3 and J2SE 5.0 Does WebObjects work with J2SE 5.0 yet? I must have missed the announcement! The last record I have is an announcement on 25 April 2006 that WebObjects is not compatible. But that was 4 months ago, so surely it is compatible by now!

If you really want a 1-to-1, A and B should share the same primary key and A should be propagating its primary key to B. If both tables have their own primary keys, and both have foreign keys to each other, things don't really stand up from a relational logic point of view because you actually have two relationships -- A is joined to B by by A.b_id and B is joined to A by B.a_id. Assuming that A.setB() is defined in terms of A.b_id, the reason B.a_id doesn't update is that B.a() is defined by B.a_id but the relationship you just set is defined by A.b_id. You have two separate relationships based on two separate keys. zak. ___ Do not post admin requests to the list. They will be ignored.

Re: WebObjects 5.3 and J2SE 5.0
I'm using WO 5.3.2 just fine with J2SE 5. However, I have seen no announcements saying that the previous non-compatibility statement has been removed, so it's caveat emptor.

Re: Converting a .strings text file to a NSArray or NSDictionary
Hi Xavier, you could read the content of your InputStream into a String and then use NSPropertyListSerialization to parse that String into a dictionary: NSDictionary dict = (NSDictionary)NSPropertyListSerialization.propertyListFromString(fileContent); Jan Am 26.09.2006 um 12:06 schrieb Dev WO: Hi:) I've got a resource in my Framework (text.strings), I know I can access a specific key using WOResourceManager.stringForKey, but I need to create an array of all the key in the file.

Re: Regular v Servlet resource manager use
Hi Gavin, First off, I know Jacques Schmidt about servlet deployment so this may be useless information. :-) This resource location is very dependent on paths. For a regular WO app, if the current working directory is not the .woa directory, resources will not be found. I expect something similar applies to servlet deployment. Check and see if there is an option for changing the current working directory or things like that.

The main goal is to allow users to search large-full text columns, returning enterprise objects. I have broken this into three specific requirements as I can't seem to fulfill more than two, regardless of approach. 1) Search for strings in a large text column using Frontbase's full text index (requires SQL such as ...where SATISFIES (full_text_index, search_string) 2) Allow user input and pass this as a parameter to the fileSpec for a query. 3) Create or return EOs so as to have relationship information so as to provide key value coding to related tables. It seems I'm missing something as I can only meet two of the three above at a time. Here are the options performed so far: A) Using rawRowsForSQL I can do 1 and 2 above. I have converted the results into enterprise objects but do not know how to perform an addObjectToBothSidesOfRelationshipWithKey which would allow access to related objects (such as code tables). I am not following what your problem here is. If you have an eo as converted from (1) and (2) why can you not do eo.addObjectToBothSidesOfRelationshipWithKey(tag, tag)? Yep. A fair point and there's a good chance I'm looking at this cockeyed. A more detailed explanation: I'm pulling back Report rows using rawSQL. Once I get the rows back, I'm iterating through, creating Report objects and setting their values based on data retrieved in the SQL query. OK, that sounds really wrong. I then add these all to an array and can display them nicely in a WORep I am not pulling back object IDs (primary and foreign keys) in the SQL query because the OIDs are not part of the EOModel; Surely the OIDs are part of the EOModel. I will assume that you mean they are not class properties of the entities, but that they are defined in the EOModel. Otherwise, I can't see how EOF could work. So, as they are part of the EOModel, you _can_ pull back the values using your rawRowsForSQL. So what you want to do is to pull back the OID, and then use EOUtilities.objectFromRawRow to convert raw rows into EOs. Note that any data you pull back with the rawRowsForSQL will _not_ be used by objectFromRawRow. So, unless you need to display some of that information before converting raw rows into EOs, you can make it more efficient by just selecting the OID. What is usually done is to select some of the data and the OID and display the partial data. Once the user indicates which rows will be used in a process, turn those rows into EOs. One potential issue with this is that objectFromRawRow works on one EO at a time, so for large numbers of EOs, that is a lot of trips to the database. IIRC, you can construct a manual array fault and have EOF fetch them all in at once, though I don't recall the methods at the moment. Let me know if you need this. Chuck I can't set their values. So, given my knowledge (admittedly limited), I don't have foreign keys in Report with which I could addObjectToBothSidesOfRelationshipWithKey. If I had these as complete objects I'd do as you suggest aReport.addObjectToBothSidesOfRelationshipWithKey( aCompetitor, toCompetitor) and that would work great. I'm sure there's some way of accomplishing this that I have not considered. I've checked this list, Frontbase's list, and Practical WebObjects. Perhaps I'm looking for the wrong things. B) Using objectsWithFetchSpecificationAndBindings I can do 2 and 3 above. But EOModeler does not allow the SATISFIES term, even when typing it into the fetchSepc in Use Raw SQL Expression. You would need to extend EOF to do that. Pierre Bernard's qualifiers would be the place to start for this. C) Using a stored procedure I can do 1 and 3 above. However, I do not see a way of passing a user-defined search into the store procedure from WebObjects. No ideas on that. Perhaps there is a much better and non-database specific way to quickly search large text fields with features such a stemming, wildcards, etc. For a non-database specific way, see http://lucene.apache.org/ The basic idea is much like handling the rawsRowsFromSQL result: you index the text and store the entity name and PK with the text. Do a Lucene search, and convert the entity name and PK back into an EO. It takes a while to wrap your head around it.

Re: constructing a url...
I display JFreeChart graphs all the time. In this particular graph, a bubble graph, I need to popup a window with the project. Everything is HTML with an image map. The way jFreeChart renders it, it calls a method to create the imagemap urls. I can control that and have wonderfully with a DirectAction. What I am trying to do instead.. I can pass the context to that aforementioned class, is to somehow create a component action url with just passing it the context and I guess the project EO. At that point I am a bit lost on how to create the URL that can actually reference the project. Thanks James On Sep 25, 2006, at 3:14 PM, Sam Barnum wrote: So the actual JFreeChart graph is not displayed in an HTML page, but as a swing component, correct? I think you're probably going to need to go with DirectActions. Because component actions depend on a context object.

OK -- Here is the real problem I need for the popup page to know the parent page so that javascript can do its magic.

Chuck, Thanks for the pointers (again). You are correct. I do, of course, have OIDs in the EOModel. I misspoke on that point. I am not, as you pointed out, including them in the class properties.

The main goal is to allow users to search large-full text columns, returning enterprise objects. I have broken this into three specific requirements as I can't seem to fulfill more than two, regardless of approach. 1) Search for strings in a large text column using Frontbase's full text index (requires SQL such as ...where SATISFIES (full_text_index, search_string) 2) Allow user input and pass this as a parameter to the fileSpec for a query. 3) Create or return EOs so as to have relationship information so as to provide key value coding to related tables. It seems I'm missing something as I can only meet two of the three above at a time. Here are the options performed so far: A) Using rawRowsForSQL I can do 1 and 2 above. I have converted the results into enterprise objects but do not know how to perform an addObjectToBothSidesOfRelationshipWithKey which would allow access to related objects (such as code tables). I am not following what your problem here is. If you have an eo as converted from (1) and (2) why can you not do eo.addObjectToBothSidesOfRelationshipWithKey(tag, tag)? Yep. A fair point and there's a good chance I'm looking at this cockeyed. A more detailed explanation: I'm pulling back Report rows using rawSQL. Once I get the rows back, I'm iterating through, creating Report objects and setting their values based on data retrieved in the SQL query. OK, that sounds really wrong. I then add these all to an array and can display them nicely in a WORep I am not pulling back object IDs (primary and foreign keys) in the SQL query because the OIDs are not part of the EOModel; Surely the OIDs are part of the EOModel. I will assume that you mean they are not class properties of the entities, but that they are defined in the EOModel. Otherwise, I can't see how EOF could work. So, as they are part of the EOModel, you _can_ pull back the values using your rawRowsForSQL. So what you want to do is to pull back the OID, and then use EOUtilities.objectFromRawRow to convert raw rows into EOs. Note that any data you pull back with the rawRowsForSQL will _not_ be used by objectFromRawRow. So, unless you need to display some of that information before converting raw rows into EOs, you can make it more efficient by just selecting the OID. What is usually done is to select some of the data and the OID and display the partial data. Once the user indicates which rows will be used in a process, turn those rows into EOs. One potential issue with this is that objectFromRawRow works on one EO at a time, so for large numbers of EOs, that is a lot of trips to the database. IIRC, you can construct a manual array fault and have EOF fetch them all in at once, though I don't recall the methods at the moment. Let me know if you need this. Chuck I can't set their values. So, given my knowledge (admittedly limited), I don't have foreign keys in Report with which I could addObjectToBothSidesOfRelationshipWithKey. If I had these as complete objects I'd do as you suggest aReport.addObjectToBothSidesOfRelationshipWithKey( aCompetitor, toCompetitor) and that would work great. I'm sure there's some way of accomplishing this that I have not considered. I've checked this list, Frontbase's list, and Practical WebObjects. Perhaps I'm looking for the wrong things. B) Using objectsWithFetchSpecificationAndBindings I can do 2 and 3 above. But EOModeler does not allow the SATISFIES term, even when typing it into the fetchSepc in Use Raw SQL Expression. You would need to extend EOF to do that. Pierre Bernard's qualifiers would be the place to start for this. C) Using a stored procedure I can do 1 and 3 above. However, I do not see a way of passing a user-defined search into the store procedure from WebObjects. No ideas on that. Perhaps there is a much better and non-database specific way to quickly search large text fields with features such a stemming, wildcards, etc. For a non-database specific way, see http://lucene.apache.org/ The basic idea is much like handling the rawsRowsFromSQL result: you index the text and store the entity name and PK with the text. Do a Lucene search, and convert the entity name and PK back into an EO. It takes a
Re: constructing a url...
James, I've done something similar to this, but quite a few years ago. I haven't followed this whole thread, but maybe the same concept will work for you. I created a ClosePopUpPage component that I would call from my pop up page submit action. (So right off the bat, any changes in the pop- up page are processed.) When the ClosePopUpPage loads, the javascript in the onLoad does something like (this is from memory) window.opener.submitFromPopUpForm.submit(); window.close(); This relied on an informal interface that the form to be submitted on the main window had a certain name. And you needed to make sure the resulting action didn't do anything unexpected. But the end result is that the changes in the pop-up were reflected in the refreshed main page. Hope this can help in your situation. Regards, Mark On Sep 26, 2006, at 5:20 PM, James Cicenia wrote: I know this is confusing My app has a lot of popups.
