Re: [SOLVED] com.reportmill.base.RMException: Probable fatal error:No fonts found.
Hi David/ Mike, Thanks for your time and suggestions. We have tried Mike's suggestions, but that did not help fix this issue, so we went on doing more investigation... (sorry for the delay in response, we were banging our heads to figure the solution... and lost in the herd ;) ) Finally, we got this issue (fonts problem) fixed by running the following *simple* command: -- sudo apt-get install msttcorefonts -- This command installed all the fonts and we're able to get the reports! Hurray!!! For more info, please checkout this article from my friend Kamal - http://www.kamaldshah.com/2011/06/linux-not-for-faint-hearted.html#links Thank You, Shravan Kumar.

However, if I try to access such a website, I get the Access Forbidden error.

Hope you will continue your support to WO Community going forth! Why not build another Mike? I hope you will strive for tremendous growth of WO inside Apple :) and we wish for that. I really think there is no other better framework other than WO. Spring, Hibernate, Tapestry, ... are all just adding pepper to wound! I wish for success :) Cheers, Shravan Kumar. M Fw: announcement announcement Wed Apr 21 22:03:26 2010 From: Mike Schrag msch...@pobox.com To: WO Dev Group webobjects-dev@lists.apple.comHey everyone ... I wanted to let you guys know that Apr 30 will be my last day at mDimension. A few weeks ago, I accepted a position at Apple. Not to worry, though -- supporting WOLips and Wonder will be part of my responsibilities, so I'm far from disappearing. I think iTMS has done a really good job demonstrating that they're committed to contributing, with Entity Modeler app, eomodeldoc, and a substantial amount of work recently with ERModernLook. The folks over there appreciate the value of the WebObjects and Wonder communities, and I look forward to a lot of exciting things in the future. As far as mDimension, we are parting on really good terms. They have been a great company to work for over the past 5 years. For years before I came on, Bill would tell me about this framework called WebObjects and how great it was. When I started at mDT, he got me going with WO with a bunch of books, WWDC videos, and helpful guidance, and they set me on The Path. mDT has also consistently made a substantial investment in the community, supporting every bit of development that I've done in WOLips, Wonder, WOWODC, and the build servers throughout my time here, and I applaud them for that. For the things you guys may directly care about: * WOLips - still working on it * Wonder - still working on it * Build Servers - mDT will continue to host the build servers * WOWODC - still attending, though not in an official Apple capacity To contact me in the future, my AIM/twitter are the same, but you can use my msch...@pobox.com email address. ms ___ Do not post admin requests to the list.

Re: Long Fetch times
Hi Jeff,
Just few questions to nail the problem:
1) When you execute the queries logged in your earlier directly in the
database, does it have same performance/ same time to execute as you experience
in the WO.
2) Try rebuilding table indices.
3) Just see if any data is corrupted in your database, there by it consumes so
much time to retrieve data.
4) Might be your disk has slowed down and is not timely responding... time to
replace with new disk ;-)
See if any of the above nails out your issue and helps solve the problem... if
so, just post back your experiences!!!
Best Regards,
Shravan Kumar. M

little more info. Here's the actual code that is doing the long
running fetch, followed by the sql generated by the code. Note there
there isn't all that much data in the databaes, and the fetch itself
finds no matches...
EOQualifier poolQual = Pool.POOL_TYPE.eq((int) poolType).and(
Pool.NAME.likeInsensitive(name));
ERXFetchSpecification poolFetch = new
ERXFetchSpecification(_Pool.ENTITY_NAME, poolQual, null);
NSArray String keyPaths = newNSArray(newString[] {Pool.ENTRIES_KEY,
Pool.ENTRIES_KEY+ .+ Entry.COMBO_TEAMS_KEY,
Pool.ENTRIES_KEY+ .+ Entry.COMBO_TEAMS_KEY+ .+
ComboTeam.TEAM_POPUPS_KEY,
Pool.ENTRIES_KEY+ .+ Entry.ENTRY_ADMIN_KEY});
poolFetch.setPrefetchingRelationshipKeyPaths(keyPaths);
Pool pool = (Pool)
ec.objectsWithFetchSpecification(poolFetch).lastObject();
return pool;

Eclipse: Generate Getters and Setters
Hi Group,
When ever I use Source - Generate Getters and Setters... function in Eclipse
it generates getter method as of Java Bean style like:
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
But I wish the getter method generates like a native WO getter method i.e.,
public String name() {
return name;
}
Is there any setting I can modify to achieve this? Please advise.
Thank You in advance,
Shravan Kumar. M

Re: refresh EC after call to ERXEOAccessUtilities.updateRowsDescribedByQualifier()?
Mike's precautionary measure is ticking at the top of my mind... so may be for the time being I will just call ec.refreshAllObjects() just to be integral, consistent, simple and more importantly let not annoy EOF by mistake!!! I will however, keep Anjo's trick in mind and plan for its implementation slowly. Just a thought, I see Anjo's thought and this issue fix should go into wonder and may go into these API's like: updateRowsDescribedByQualifier(EOEditingContext ec, String entityName, EOQualifier qualifier, NSDictionary newValues, boolean shouldUpdateECPostOperation) and similar one for deleteRowsDescribedByQualifier() API.

Re: Qualify data based on non-class property
Thanks for your response Clark. Actually, I have a list of customers which I have to filter based on their sales... but for that I have to build a qualifier to filter the data. So, I will get customer Object reference from sales's objects, and finally I have to extract all the customers having sales... occasionally I have to build qualifiers for the non-class properties :) Thank You, Shravan Kumar. M -- Am I correct in assuming that sales.toCust() is a related EO?

Re: [OT] Weird Boolean/ Wrapper class bug
Hello Mike,
Its the same code I have showed you (except that I changed variable names for
simplicity), and there is no line of code that is missing. Where a is the EO
property and when I check for it ( if(a != null) JRE throws NPE and when I
check for if(a == null), JRE enjoys ), its throwing exception as stated. I
believe this is a bug with JRE, and it seems to be fixed as per David's testing
in later versions of JRE.
I think fix would be JRE shouldn't have unboxed it if its null... and they
seems to have realized this mistake in later versions of JRE... But its
wondering how a null not null check differs in this world and they are not
same from JRE perspective!!! If its an error it should have thrown error
always...

Subject: Re: [OT] Weird Boolean/ Wrapper class bug
You're not pasting the real code, I don't think. I suspect you're just getting
screwed by autoboxing in whatever code you're not showing. If you have:
Boolean a = null;
boolean b = a;
That will result in a NPE as auto-unboxing attempts to unbox a into a boolean,
which throws a NPE. Somewhere in the code you didn't include is an unbox into a
boolean (little b) of your null Boolean.
So, for instance:
Boolean a = null;
if (a) {
}
will NPE. Look more closely at the exact code, specifically the line of code
that actually failing, and make sure you're not getting an unbox.

Re: [OT] Weird Boolean/ Wrapper class bug
Thanks for your example and analysis Mike. When I run your example from a
simple file over command-line everything is fine and when I put this code this
Application.java, even then its fine...
But the error happens from a EO class and when I debug and test this code
snippet in Display view, same error is shown there... so, the problem is
getting more interesting and fuzzy. One thing I can surely say, error is
inconsistent and is reproducible.

Incidentally, boxing/unboxing actually happens at compile time ... Once you run
that code and verify if it works or not, then do the same inside of Eclipse and
see if it fails (assuming you are compiling this from eclipse not javac). If
that fails, run
javap -c Test
and you can see the decompiled code ... There should be no boxing/unboxing
calls (basically, you shouldn't see an invokevirtual except for the println),
you should just see an ifnull.

Session.defaultEditingContext() has automatic locking - you do not have to do it manually. So, if you continue using that EC you can take out the locking code. The best solution would be to use an EC other than Session.defaultEditingContext and use one of the frameworks that provides auto-locking.

Re: WOLongResponsePage issues
Thanks George. I was doing same, debugging the code, and trying to pull odd man out ;-) I think I have finally found the issue of LongResponsePage not getting refreshed. In the performAction() method the business logic is LOCKING the session's defaultEditingContext and performing the business operation and soon after this LongResponsePage thread is blocking and failing to refresh. Once, LongResponsePage operation thrown an error of editingContext is not locked. So, I locked it and unlocked it as well!!! Am wondering how should I perform my business operation without locking my editingContext?

Hi Tim, Thanks for your suggestion. I have changed my longresponse code to create a temporary ERXEC's editingcontext and then once the process is completed am localizing the content to my old ec. This has solved the issues of locking/ unlocking ec. However, I see that many links pointing to WOCode.woa end up with No instance available,reason might be the app may be down. I tried to get the MultiECLockManager residing in WOCode.woa site as referred in WO wiki, but link is broken!!! Don't know who will take care of this issue? Thank You, Shravan Kumar.

Session.defaultEditingContext() has automatic locking - you do not have to do it manually. So, if you continue using that EC you can take out the locking code. The best solution would be to use an EC other than Session.defaultEditingContext and use one of the frameworks that provides auto-locking. You could use MultiECLockManager or Wonder's ERXEC and they lock automatically. Tim UCLA GSEIS On Jul 24, 2009, at 11:34 PM, Shravan Kumar. M wrote: Thanks George.

Objet : WOLongResponsePage issues
Hi Group,
I am having trouble developing a long response page!!! I have developed a page
which extends WOLongResponsePage component and implemented performActionI(),
... methods. I have actually referred to SimpleRefreshPage example from
WebObjects distribution.
Am not sure what the problem is, but I have various issues:
1) Not able to create a component in pageForResult() method (error says,
context is null, ...). So I have created the component in the calling page and
passing the created component to long response and returning this component in
pageForResult() method. But I have read in WO that, if a component is created
and cached in a variable, we have to invoke ensureAwakeInContext(context)
method to make sure the cached component is awakened and is up in the session
store.
2) I have placed a flash movie (.swf file) in the long response page, so the
movie plays and replays as the page refreshes (this flash movie does not read
any value from long response page like: status of long response, ...).
3) Issue: The long response page is NOT refreshing and after some time No
instance available message is shown in the browser, but note that server is
continuing processing my request.
4) Below is the code snippet from my long response page:
Number refreshCount = new Integer(1);
public void appendToResponse(...) {
setRefreshInterval(refreshCount);
super.appendToResponse(...);
}
public Object performAction() {
Object value = processImages();
//value is of boolean type
return value;
}
/**
User CImage are EO's and we using session's defaulteditingcontext
here.
*/
private boolean processImages() {
User usr = ((Session)session()).loggedInUser();
boolean isSuccess = CImage.processImages(usr);
return isSuccess;
}
public WOComponent pageForResult() {
return nextPage;
}
public WOComponent refreshPageForStatus() {
return this;
}
5) If anyone could advise me do's and don'ts of WOLongResponsePage coding and
best practices, that would be great. I see we are really
Re: Can I use WOMultipartIterator API in WOComponent action methods?
Thanks for your response Lachlan Deck. You are right! I can use context().request().formValues(), but as I said in my earlier email, I get image data from request which I cannot read from context().request().formValues() and is only available by iterating over WOMultipartIterator API. Hence, it is must for me to grab request data using WOMultipartIterator API. --- * From WebObjects API:* public class *WOMultipartIterator* extends java.lang.Object This class represents the content of a multipart/form-data HTTP request. You get the iterator for such a request by calling |multipartIterator| on the WORequest object. Once you have this object, you get WOFormData objects by repeatedly calling |nextFormData|, until it returns null. Each WOFormData allows you to introspect the sub-headers, as well as either look at the form value(s) or grab the entire content of the part as an InputStream subclass. The InputStream subclass is a WOFormDataInpuStream and can be used to stream large file uploads to disk (or elsewhere). *The WOMultipartIterator should NOT be used with WOFileUpload component actions. It may be used with component actions where there is no WOFileUpload, and it may be used in DirectActions. * --- From above API, I get to know I can use WOMultipartIterator API in either component actions/ direct actions.

Thanks Mike. We are struggling around this issue since long time with some workarounds, but we did not have any good solution yet. Your solution worked out well. Thank You Shravan Kumar. M effigent India Pvt., Ltd., Subject: One Less Mystery From: Mike Schrag [EMAIL PROTECTED] Date: Mon, 14 Jul 2008 19:27:04 -0400 To: WebObjects Development webobjects-dev@lists.apple.com To: WebObjects Development webobjects-dev@lists.apple.com One of our guys got tripped up because his hostname was floating between what we expected it to be and his IP address. After some digging, I've resolved a mystery (well, it was a mystery to me .. maybe other people knew about it :) ). If your CGI adaptor URL is http://127.0.0.1/cgi-bin/WebObjects, at runtime, WOApplication converts that to http://application.hostAddress()/cgi-bin/WebObjects. If you CGI adaptor URL is http://localhost/cgi-bin/WebObjects, at runtime, WOApplication converts that to http://application.host()/cgi-bin/WebObjects. application.host() considers your -WOHost setting, hostAddress uses InetAddress.getByName(host()). So if you've ever been confused and perplexed as to why your app keeps using your IP address even when you set WOHost, this is why. This is especially a problem when you're testing with cookies on your local machine, which is really sensitive to host name changing. Part of the confusing part here is that WOLips defaults to 127.0.0.1. I think this is wrong and I'm about to change it (unless someone has a good reason behind it). In the meantime, you can to several things: 1) Change the WOAdaptorURL in your launch config (to change this on a per-app basis) 2) Change the WOAdaptorURL in Preferences=WOLips=Launch. This will change the defaults globally. I don't recall if this cascades to existing run configs or not. So to be safe and make sure your app works in dev like it does in deployment (which would have a consistent hostname), set WOAdaptorURL to http://localhost/cgi-bin/WebObjects and add a -WOHost yourhost.local (or whatever your fixed hostname is). ms ___ Do not post admin requests to the list.
