Re: WOLips strange behavior

2014-04-15 Thread Filippo Lauria

Hi Ray,
thank, you too, for reply.


How did you get your WOLips?


I just installed it 
automatically from eclipse (v3.7r2 20120216-1856
)
.

 The version of WOLips is
 3.7.20140223.48.


I always do the install through the update manager. Currently, I am
using eclipse version 3.7.2 (Build id: I20110613-1736) and I have
WOLips version 4.2.20130127.7.
I thought
 that with eclipse 3.7* one can only install WOLips 3.7*
.
Anyway, to prove this on my skin, I just tried to install (since 4/5
months ago) 
WOLips 4.2, too.
The result was (on an Ubuntu OS whit eclipse 3.7) that there were
thrown a lot of NPE exception
while normally using the plugin.


I did not read your earlier e-mail carefully because messages that have
WOLips strangeness in the title are singing an old, old song. But.
Data loss errors in eclipse/WOLips are unusual. And bad.

I do not know if you would be willing to do it, but if this was me, I
would move aside my workspace and start eclipse and re-create the
workspace and re-create my projects. If data from files is being lost,
what else is to be done? Not losing data is pretty basic. I have
screwed up my eclipse installations many times yet I have not seen a
data loss error.
Ok. I forget to say that this is my fifth new brand workspace. In the
earlier ones i did not figure out
where the problem exactly was. Now I individuate it on the trashing of
a woo file of the component
EditAssignmentPage.

I assume you are not running out of disk space. It is hard to know what
else could cause this. If you re-create the workspace and it still
happens, give a holler off-line because this really would need to be
looked at more seriously.

Sorry I cannot think of anything else to help you out.
You've already done enough, don't worry. Maybe it is only a
misconfiguration on my machine,
a false positive

, I hope.

Anyway, when I'll have more details, I will let you know.

Regards.

cheers - ray

  Hi Filippo,
 
 Hi Aaron, thanks for reply.

 Probably you upgraded your WO plugin for Eclipse called WOLips or
 maybe
  you even upgraded Eclipse too.
 
 I don't.
 I'm an Ubuntu WebObjects developer [ I think the last one on the
 earth :) ] and
 I'm using eclipse 3.7 + WOLips 3.7.

 
  Sometimes they are written to handle line endings and things
  differently and will modify old files just by opening them if
  you've upgraded WOLips.
 
 The problem is that WOLips is not just trimming spaces, or stripping
 line endings or \soft stuff\ like this, it is \brutally\ cutting off
 lines of code!

 I was just wondering if there was someone else who experimented this,
 or I'm the only one?

 Thank you all,
  Filippo

  Hello,
  I'm facing an issue that it's really driving me crazy.
 
  Here it is a brief explanation:
 
  I have a component from one of my WO framework: EditAssignmentPage.
  I was not touching it anymore, since my focus moved to other
  components of my WO framework as well.
  I did few changes to my framework, added components, modified
  EOModel, etc.
 
  Few days ago I was wondering to change something on
  EditAssignmentPage Component. I opened it and /magically/ it just
  modified itself.
 
  I soon noticed issues in the java file, since an ERXDisplayGroup
  lost his parametrization.
  After few looks I noticed too, that woo file automatically changed
  from something like this:
  --
  {
 WebObjects Release = WebObjects 5.0;
 encoding = NSUTF8StringEncoding;
  variables = {
   offeringGroup = { ... };
   scriptDisplayGroup = { ... };
  submissionProfileDisplayGroup = { ... };
  ...
  --
 
  to something similar, but different:
  --
  {
 WebObjects Release = WebObjects 5.0;
 encoding = NSUTF8StringEncoding;
  variables = {
   offeringGroup = { ... };
  ...
  --
 
  Is there a logical explanation of why is this happening?
 
 
  Luckly, I committed EditAssignmentPage in a consi
  stent state, but I can start to modify component since it runs to
  inconsistent version.
 
  Any ideas?
 
  Thank you for reading (and hopefully for answering).

Re: Apache adaptor error with http header

2014-04-15 Thread Schoenenberger Dominique

Big thanks ! That was a good advise !

I downloaded an already compiled adaptor available with this procedure:
http://wiki.wocommunity.org/display/documentation/Installing+a+deployment+environment+on+RedHat%2C+CentOS+or+Amazon+Linuxhttp://wiki.wocommunity.org/display/documentation/Installing+a+deployment+environment+on+RedHat,+CentOS+or+Amazon+Linux

and with this apache adaptor, the problem is solved. That was a problem
impacting us for 3 years ! Thanks again !

My best guess at this point (and it is only a guess and on half a cup of

build – two threads are sharing data structures at the same time. That
explains why it is not systematic. I can’t help you any more than that,
hopefully someone else can.

The header is too long because it contains HTML code ! , usually the html is a

What version of Apache? Which adaptor version? Who built it?

That looks like a buffer overrun, or something picking up part of the previous
request.

After such error, the instance is flagged “dead” (see log above) and the
request is sent to another instance.

In user point of view, it appears as a session timeout error.

That is the result of the request is sent to another instance”.

This error is not systematic.

Does someone having the same problem ? or have any idea of the cause ?

Re: To-Many Qualifiers

2014-04-15 Thread Aaron Rosenzweig

Hello Kevin,

I’ll take a swing at a new qualifier for you.

Verbally:
A profile sometimes points directly to the account I want. Other times, the 
primary account for a profile is NOT the one I want but it has teams which 
vicariously point back to the account I want. Give me all those profiles.

Style notes (entirely optional):
Try to avoid starting with “ERXQ.anything” such as “ERXQ.or()” and 
“ERXQ.keypath()” Technically it is ok but it’s harder to rest and disrupts the 
visual flow of the code. 

Don’t use “_KEY” - It’s easier to just call “.key()” when you need it as you’ll 
soon see.

Code sniff:
Anytime you have a to-many relationship involved, consider an “exists” 
qualifier.

Utility method:
You need a way to “qualify yourself.” Your primary keys are probably hidden 
(rightly so). You don’t want to qualify on “name”, “title”, “description or 
anything else since you already have the Account object you want in hand. So 
put this utility method either in your “Account” EO or preferably in your 
abstract parent class if you have one (between “Account” and 
“ERXGenericRecord”):

public EOQualifier identityQualifier() {
EOEntity entity = 
ERXEOAccessUtilities.entityNamed(editingContext(), entityName());
EOQualifier qualifier = 
entity.qualifierForPrimaryKey(primaryKeyDictionary(false /*inTransaction*/));
return qualifier;
}

The new code:

// Generates a qualifier for the Profile for this account and the Profiles of 
any account on the same team (or that is the intention)
public static EOQualifier visibleToAccountQualifier(Account account)
{
EOQualifier accountIsDirectlyTheOneIWantQualifier = 
account.identityQualifier();
EOQualifier accountHasTeamForTheOneIWantQualifier = new 
ERXExistsQualifier (
account.identityQualifier() /*subQualifier*/,
Account.TEAMS.dot(Team.ACCOUNTS).key() /*baseKeyPath*/,
);
EOQualifier finalAccountQualifier = new ERXOrQualifier(
accountIsDirectlyTheOneIWantQualifier,
accountHasTeamForTheOneIWantQualifier);

EOQualifier profileQualifier = new ERXExistsQualifier (
finalAccountQualifier /*subQualifier*/,
Profile.ACCOUNT.key() /*baseKeyPath*/, /*Note: this is a to-one 
relationship, but that’s ok*/
);

return profileQualifier;
}


Wrap-up:

Note: be sure to either update Wonder or at least “cherry pick the latest 
version of the ExistsQualifier.

Kevin give this a try and report back. It’s funny how the ExistsQualifier can 
solve 90% of the complex data-mining queries we could encounter. This is 
especially true for “to-many” relationships. 

You can “flip” the “exists” sql into an “in” with an additional boolean 
parameter. Play with the true-false value of “useInClauseInstead” to tune 
performance. If you want to learn more then watch the slides here:
http://www.chatnbike.com/presentation_existsQualifier/

You’ll be able to lick this, don’t worry. Dig in :-)

 Hello,
 
 I was hoping someone would be able to point me in the direction of how to 
 handle generating a to many qualifier that involves a key path (not just a 
 single key).
 
 A code example:
 
 // Generates a qualifier for the Profile for this account and the Profiles of 
 any account on the same team (or that is the intention)
 public static EOQualifier visibleToAccountQualifier(Account account)
 {
EOQualifier profilesDirectlyTiedToAccount = 
 Profile.ACCOUNT.eq(account);
String teamProfilesKeyPath = ERXQ.keyPath(Profile.ACCOUNT_KEY, 
 Account.TEAMS_KEY, Team.ACCOUNTS_KEY);
EOQualifier teamProfilesQualifier = ERXQ.has(teamProfilesKeyPath, new 
 NSArrayAccount(account));
return ERXQ.or(profilesDirectlyTiedToAccount, teamProfilesQualifier);
 }
 
 Performing a fetch with this qualifier generates the following error.
 
 EvaluateExpression failed: com.webobjects.jdbcadaptor.PostgresqlExpression: 
 SELECT DISTINCT t0.id FROM Profile t0 INNER JOIN Account T1 ON t0.accountID 
 = T1.id INNER JOIN AccountTeam T2 ON T1.id = T2.accountId INNER JOIN Team T3 
 ON T2.teamId = T3.id INNER JOIN AccountTeam T4 ON T3.id = T4.teamId WHERE 
 (T4.teamId IN ( SELECT Team.id FROM Team,AccountTeam null WHERE 
 Team.id=T4.teamId AND null.accountId IN (1)  GROUP BY Team.id HAVING 
 COUNT(*)=1 ) OR t0.accountID = ?::int8) withBindings: 1:1(accountID):
Next exception:SQL State:42601 -- error code: 0 -- msg: ERROR: syntax 
 error at or near null
  Position: 281.
 
 There is a null in there where there shouldn't be one (on the inner select). 
 Am I using this qualifier incorrectly or is this indicative of a modelling 
 error or even a bug? If it helps, I'm using PostgreSQL.

Convert WebObjects app to pure java

Hello all,

We're looking to convert one of our WebObjects Apps to pure java. Wondering
if there's a tool which could help with this process. The application is
running WO 5.4 on Java 5.

Any advice would be greatly appreciated
