Many to many relationship... some problem
Hi.. I'm having some problem with a many-to-many relationship. I've two entities: Order and Product. They have a many-to-many relationship, and an attribute: quantity. The strange thing is that I don't see the OrderProduct model generated... Well.. to be honest I don't understand how many-to-many works... (In WO.. I know the DB-theory)... Some kind help?

Re: True war deployment and WebServerResources
Sorry if the reply is posted in another topic, as i've just managed to reactivate my account on this mailing list. So here's what i found : When adding in the Application constructor registerRequestHandler(new WOResourceRequestHandler(), _wr_); WOImage are correctly shown. However ERXStylesheet and ERXImage are not. I guess they are still using an ERXResourceHandler, i didn't take the time to investigate further. Now, how can i produce a zip containing all the web resources (from the app and jar frameworks) with maven ? It's needed when turning deployment mode on in web.xml. Finally everything seems to work quite ok : last WOLips version let me edit wod and eomodeld with the maven project layout, building a true war works... Well the last piece of the puzzle is enabling fast developpement with the build in eclipse. Andrew Lindesay faces the same issue with his message War / Maven / Jar Build – How Does it Work wi th Eclipse's Build Automatically?

Mavenization worked well and i can package my app as a true war... but when deployed in a servlet container (for example with mvn jetty:run-war) the WebServerResources cannot be found (while they are at the right place inside the jar). I've attached a sample project reproducing the problem with a simple WOImage and ERXStylesheet. Has anyone already encountered this ? I'm not sure it has something to do with wonder.

Re: Getting into WebObjects?
On 03/08/2009, at 12:23 PM, Brian Wachter wrote: I have a license of WebObjects (along with 3 WO books) that I purchased several years ago, which has been sitting on the shelf. The reasons being (1) web development is an ancillary part of my current job and I’ve not had any projects that required the technology and (2) because I’ve been reluctant to invest time in what I’m thinking is a limited-userbase/ dead technology. Dead, no; mature, yes; and certainly moving forward. Limited, well somewhat niche, sure, but has a vibrant user-base. I’ve got some dynamic-driven web-based development projects on the horizon, so before I eBay my WO license, I thought that I’d solicit feedback from the WebObjects community as to whether you would recommend WO as a solution for dynamic-driven sites. In general, yes. I don’t know Java, What do you know? it seems EOModeler has been deprecated, Yes, the Apple-tools are no longer used. These days Eclipse/WOLips is the apple/community sponsored toolset. http://wiki.objectstyle.org/confluence/display/WOL/Home and I’m guessing that the books and documentation that I have are antiquated. Perhaps but they'll still be a useful reference though the examples might need translating to the different toolset. Which books? So, I’m thinking that I’d have a steep learning curve. It certainly will be somewhat steep. I’m also wondering what the popular alternatives to WO may be. Will depend somewhat on what you know or are willing to learn. php, Ruby on Rails, Python, Grails (Groovy) etc Or perhaps you just want to use something pre-built with cms functionality like drupal which has lots of plugins for various functionality. Depends on what you're trying to achieve. Thanks in advance for the feedback! with regards, -- Lachlan Deck ___ Do not post admin requests to the list. They will be ignored.

Re: Many to many relationship... some problem
To do what you want you probably want to set those relationships (ordine and prodotto) to be class properties. Just a guess, but it looks like what you're trying to model is a line item; it might make more sense if you think about it that way (i.e. order --- line item --- product) instead of a many-to-many relationship.

Re: Many to many relationship... some problem
Ok.. I'll postpone this,, Now.. for the model I was thinking at this: Order - LineItem(has quantity as attribute) - Product This should solve the to-many problem.. To save the cart... I thought to: Customer - LineItem Or: Customer - Cart - LineItem (Cart entity is useless, but I can add a LastUpdated date ...) What do you think?

RE: dispatchRequest not seeing InputStream data from uploadFile request
Yep, I'm using WOnder.
Incredible as it may sound, added the 'name' attribute to the WOFileUpload
element in wod and worked!
This thing is like something you wouldn't think make the difference.
This is basically what I did:
-took the DA from FileUpload project in Examples folder, where they use the
Iterator to upload the file and added the 'name' attribute to the WOFileUpload
element, as that DA seeks for the name of the WOFileUpload and ta-dah!.. worked!
Thanks!

Tiger, Eclipse with WO5.4 in Leopard and finally using Eclipse with
WOnder 5.4 in Leopard. All worked with no problems. If I needed to
grab the file contents I could do it either in createRequest,
dispatchRequest or in the DA method or the action object-method in
case I wanted not to use DAs.
But then I moved to the non-working app and I can see file contents
in createRequest method --I can even save the file-- but as soon as
execution gets to dispatchRequest, and though I get a valid object
when I issue the call InputStream input =
part.formDataInputStream(); --input is valid object-- I don't get
any data from the call input.read(buffer, offset, length - offset);
or input.available() all I get is a -1 which means there's no data.
I don't have an awake method, that I think is the next method in
execution after createRequest gets called and before dispatchRequest
gets called too.
Does anybody had experienced something simliar? or have a clue of
what could be causing to loose data?. I checked the encoding for the

I'm not sure where, but I think the encoding is getting changed. Are

Re: [SOLVED] dispatchRequest not seeing InputStream data from uploadFile request
Big correction!
It wasn't just adding 'name' atrribute to WOFileUpload element...
better still, that hasn't to do anything about it.
The thing that was broking all was that there was a method call which
went through the WOFormData iteratively to extract some partValue and
that caused the stream to be closed at the end of the loop which the
next read caused to be at the EOF. So rearranging code I was able to
not need to went through that loop and the file was read successfully.

Maybe some ideas what's causing this to happen. It is an intermittent error I get which I stuck pondering what is causing it. I have search the lists and found some relevant information but I can't quite put my fingers on it as I am new to WO. I am using WO 5.4.3 with the latest wonder source. and I get this error sometimes. incrementSnapshotCountForGlobalID: er.extensions.eof.ERXDatabase er.extensions.eof.erxdatab...@64d42f -- is unable to increment snapshot count for object with global ID _EOIntegralKeyGlobalID[State (java.lang.Long)72] - no snapshot exists java.lang.IllegalStateException: incrementSnapshotCountForGlobalID: er.extensions.eof.ERXDatabase er.extensions.eof.erxdatab...@64d42f -- is unable to increment snapshot count for object with global ID _EOIntegralKeyGlobalID[State (java.lang.Long)72] - no snapshot exists at com .webobjects .eoaccess .EODatabase.incrementSnapshotCountForGlobalID(EODatabase.java:1062) at er .extensions .eof.ERXDatabase.incrementSnapshotCountForGlobalID(ERXDatabase.java: 180) at com.webobjects.eoaccess.EODatabase.setResultCache(EODatabase.java:389) at er.extensions.eof.ERXDatabase.setResultCache(ERXDatabase.java:220) at com .webobjects .eoaccess .EODatabaseContext ._populateCacheForFetchSpecificationEditingContext (EODatabaseContext.java:2333) at com .webobjects .eoaccess .EODatabaseContext ._objectsWithFetchSpecificationEditingContext(EODatabaseContext.java: 3042) at er .extensions .eof .ERXDatabaseContext ._objectsWithFetchSpecificationEditingContext (ERXDatabaseContext.java:57) at com .webobjects .eoaccess .EODatabaseContext .objectsWithFetchSpecification(EODatabaseContext.java:3195) at com .webobjects .eocontrol .EOObjectStoreCoordinator .objectsWithFetchSpecification(EOObjectStoreCoordinator.java:488) at com .webobjects .eocontrol .EOEditingContext .objectsWithFetchSpecification(EOEditingContext.java:4069) at
