Re: SmartGWT 1.0 Released

2008-11-23 Thread Sanjiv Jivan

 company, I only talk from experience. I
 used the JavaSciprt ExtJS framework for a big project for a full year
 and I understand exactly when people say the documentation is poor and
 performance slow. Having embranced GWT to progress and to make my life
 easier, I would never want to to have the same problems again with Js
 frameworks, even less with GWT frameworks with embed the same old Js
 issues, like gwt-ext or smartGWT.

 GXT is a completely different matter and I think it is a top
 framework. I have been using it for a few months now and never gave me
 any major issues. It is a pure GWT implementation, no javaScriptObject
 or JSNI. Period.

 Huge credit to Sanjiv for his work on smartGWT, but personally I think
 this is the wrong approach to any GWT framework. JSNI is very useful
 if used to integrate the odd js function here and there, not as a
 foundation to a framework itself.

 Regards,
 Francesco

  Hi,
 
  I am wondering if the performance is due to too many items inside the
 demo
  or it is just slower than gwt-ext?  In gwt-ext, the demo is much smaller.

   Smart client is much better compared to ext-js as far as licensing is

   original js based smart-client as well as gwt-ext.

 Can't

Re: SmartGWT 1.0b2 Released

2009-02-28 Thread Sanjiv Jivan

Hi Benoit,You can essentially override the transformRequest(DSRequest
requeest) of DataSource and read the request parameters like startRow,
endRow, sort / filter params  and issue your own GWT-RPC call and set the
returned data on the DataSource.

Several users have asked for such a sample and I'll definitely add it. Its
just that other higher priority items and releasing 1.0b2 had taken
precedence. I'll post updates when such a sample hits SVN on the SmartGWT
forum.

Thanks,
Sanjiv

 Can you add as example in your showcase of a datasource using RPC

[ANN] SmartGWT 1.1 Released

2009-05-20 Thread Sanjiv Jivan

Hi,
SmartGWT 1.1 has been released.

Here's the release announcement :
http://www.jroller.com/sjivan/entry/smartgwt_out_of_beta_v1

Project Page : http://code.google.com/p/smartgwt/

Showcase Demo : http://www.smartclient.com/smartgwt/showcase/

The new samples can be found under the New Samples side nav item.

This release has several bug fixes and features with over 100 new API's.

Here are some of the important notes for this release :

* Support for GWT-RPC DataSource with DataBoundComponents.

* Formula and Summary fields: built-in wizards for end users to define
formula fields that can compute values using other fields,
  or summary fields that can combine other fields with intervening /
surrounding text. Available in all DataBoundComponents, easy to persist as
preferences.

* i18n support with resource bundles for 14 locales.

* Significant improvements to javadocs with tons of documentation on
various concepts. (~30MB on disk)

* Automatic databound dragging behaviors : grids and trees will now
inspect data relations declared in DataSources and automatically do the
right thing for a databound drag.

* API's to save and restore the display and selection state of various
components to/from the server in a serializable format.

* Performance improvements to various components and skins

* Several new samples. The Adaptive Filter and Adaptive Sort samples are
really neat, be sure to check them out.

Feel free to provide any feedback or suggestions.

overview of SmartGWT EE

2009-07-07 Thread Sanjiv Jivan

Hi,The SmartClient folks have released SmartGWT EE, the enterprise version
which is built over SmartGWT LGPL. I recently test drove it and have written
a detailed overview of it covering the various features it supports :

http://www.jroller.com/sjivan/entry/introduction_to_smartgwt_enterprise_edition

Even those not using SmartGWT will find some of the features it supports
very interesting, like the ability to load multiple databound components and
have their changes saved in a single batch RPC (transaction queue).

The showcase demo can be viewed here :
http://www.smartclient.com/smartgwtee/showcase/

Re: Who is using smartgwt?

2009-08-13 Thread Sanjiv Jivan

Hi Daniel,Please try upgrading to SmartGWT 1.2. Hosted mode should perform
better.  You're right that most of the resources from a compile output are
not used and so if you're benchmarking, best to actually see what's
transferred over the wire rather than the size of the output directory on
the server. The default com.smartgwt.SmartGwt module bundles all the
readable source versions that have a lot of documentation, the obfuscated /
minified ones, various tools like the Developer Console and a lot of other
resources that are pretty much never used in deployment. I'll look into
creating a module that outputs the minimal resources which will save some MB
of disk space on the server.

As for runtime performance, you can have a look at the SmartGWT showcase
which is comparable is size to a real world application having ~260 samples
and includes most widget types. If you're not using Calendar, or TileGrid
etc you can exclude these resources.

 for SmartGWT similar to GWT's theme that is simplified and
involved way less media. It certainly is possible.

I'll be happy to try to answer any other questions / concerns here, or if
you have specific questions or suggestions for improvement you can post on

 I would like to add a dissenting voice... As always, it's a matter of
 trade-offs

 Benefits:
 1) Pretty, usable, full-featured widgets, with very small up-front dev
 time.
 2) Very responsive dev team (you're awesome Sanjiv)

 Problems:
 1) Incompatible or redundant APIs. Specifically, I'm thinking of
 a. Redundant event system
 b. Datasource
 c. TreeGrid has approximately 160 methods.
 2) Lack of GWT Compiler optimization
 3) no use of ImageBundle
 4) b/c of 2  3, very request intensive.
 5) No intuitive way to customize styling

 Right now, our team is using TreeGrid, because no comparable widget
 exists, but I've been thinking we should take a look at customizing
 the gwt-incubator tree grid.

 Hi everybody,

 I am just new to GWT and experiencing a little bit with SmartGWT,
 implementing and trying to change the Tile Sort  Filtering Example
 from the Showcase
 http://www.smartclient.com/smartgwt/showcase/#featured_tile_filtering

 I am trying to implement the above example with a fuzzy search but
 without the extra SearchItems, which causes the FuzzySearch to fail
 and draw back on an EQUALS search.


 Everything works fine with the example, but here comes my  'error' /
 'bug' :
 Here is an excerpt from the code from the showcase example:

 code

 final DynamicForm filterForm = new DynamicForm();
filterForm.setIsGroup(true);
filterForm.setGroupTitle(Search);
filterForm.setNumCols(6);
filterForm.setDataSource(AnimalXmlDS.getInstance());
filterForm.setAutoFocus(false);

TextItem commonNameItem = new TextItem(commonName);
SliderItem lifeSpanItem = new SliderItem(lifeSpan);
lifeSpanItem.setTitle(Max Life Span);
lifeSpanItem.setMinValue(1);
lifeSpanItem.setMaxValue(60);
lifeSpanItem.setDefaultValue(60);
lifeSpanItem.setHeight(50);
lifeSpanItem.setOperator(OperatorId.LESS_THAN);

SelectItem statusItem = new SelectItem(status);
statusItem.setOperator(OperatorId.EQUALS);
statusItem.setAllowEmptyValue(true);

filterForm.setFields(commonNameItem, lifeSpanItem,
 statusItem);

filterForm.addItemChangedHandler(new ItemChangedHandler() {
public void onItemChanged(ItemChangedEvent event) {
tileGrid.fetchData(filterForm.getValuesAsCriteria());
}
});

 /code


 Three search items are created and fit together in the filterForm.
 Using the form and entering just a part of a Common Name, will break
 down the results with each letter I type.

 Now comes the bad part:

 I do not want the lifeSpanItem and statusItem any more. So I change

 code
 filterForm.setFields(commonNameItem, lifeSpanItem, statusItem);
 /code

 to
 code
 filterForm.setFields(commonNameItem);
 /code

 Now, trying to enter just a part of a Common Name will not break down
 my results with each letter I type, but instead the behaviour is like
 commonNameItem.setOperator(OperatorId.EQUALS)


 So what I am saying is that the search works fine for searchItems
 greater than just one TextField. My workaround therefore was to create
 a HiddenItem as follows:
 code
 HiddenItem tagsItem = new HiddenItem(tags);
 tagsItem.setOperator(OperatorId.EQUALS);

 filterForm.setFields(commonNameItem, tagsItem);
 /code

 Now I think that this can't be right. Now am I missing something? Do I
 have to use .setOperator on commonNameItem, if only commonNameItem is
 present? If yes: Which OperatorId should I choose?


 Thank you very much for your help,

 Greets,

 Jan

 I need only date value in exported data file.

 Please suggest us that how I remove time (00:00:00) value and also how I

 (1) DSRequest dsRequestProperties = new DSRequest();
 (2) dsRequestProperties.setExportAs( (ExportFormat) EnumUtil.getEnum

Smart GWT supports binding to your webservices WSDL directly without the
need for writing any additional server side binding code. Have a look at the
following samples.

I am unfamiliar with Jibx, you need to realize that GWT is completely
decoupled from the server side so 'compatibility' of a server-side
library with GWT is never an issue, it is your design and con-ops that
must be compatible with GWT. You must decide on how you are going to
communicate between your GWT client and the server. The way I see it
you have 2 choices: GWT-RPC or REST(XML or JSON). My preference for
speed is JSON REST services. So what you would do is make a RESTful
request to the server for the information, the server would then call
the Jibx method which would make the SOAP calls to the data sources
and you would convert and return that data to the GWT client. The
reason I suggested a JAX-WS(aka Metro) client is that JAX-WS and JAX-
RS objects can be compatible and you could just serialize them back
out with minimal to no translation.

Re: Web service call

2010-07-28 Thread Sanjiv Jivan

Hi Deepak,
I was just informing you about Smart GWT's capability of binding to WSDL's
directly as a possible option. Multiple calls to webservices can be made
asynchronously and the results can be presented in a grid / tabular form as
the results arrive. Implementing this using Smart GWT is trivial and you can
probably build the entire search / display interface in 200 - 300 lines of
Smart GWT client side code alone. The response time depends on the response
from the webservice itself.

Whether you call the webservice directly from the client or go through your
server depends on the architectural details and features of your
application and you're probably the best person to make that decision. For
example do you want to do some sort of caching, data cleansing, collection
of statistics etc

Re: SmartGWT?!

2010-01-13 Thread Sanjiv Jivan

SmartGWT has had the same clause since for a long time now. Read the actual
license file - COPYING.html that is included in the SmartGWT distribution.

http://code.google.com/p/smartgwt/source/browse/trunk/distro-source/core/src/COPYING.html

Since most of us are not lawyers, second guessing whats allowable or not
simply constitutes FUD. Then again if you are not comfortable using LGPL
libraries then that's another story. It's worth noting that the widely used
Hibernate library is also licensed under LGPL terms.

Sanjiv

On Wed, Jan 13, 2010 at 9:26 PM, Open eSignForms yoz...@gmail.com wrote:

Well, I'm not a lawyer either, but I assume you are referencing the clause
in Section 4 about combined works (the app you develop that uses GWT plus
some LGPL GWT library):

You may convey a Combined Work under terms of your choice that, taken
together, effectively do not restrict modification of the portions of the
Library contained in the Combined Work...

and

Convey the Minimal Corresponding Source under the terms of this License,
and the Corresponding Application Code in a form suitable for, and under
terms that permit, the user to recombine or relink the Application with a
modified version of the Linked Version to produce a modified Combined Work,
in the manner specified by section 6 of the GNU GPL for conveying
Corresponding Source.

So I'd guess you have a point as the minimal code required to allow it to
be recombined would be all of your GWT client code.

Got me! Maybe that's why vaadin and GWT chose the Apache License V2. And
it is interesting that the now obsolete gwt ext license (
http://gwt-ext.com/license/) suggests that combining the code at the java
level is where dynamic linking takes place and should not be a concern.

SmartGWT LGPL as you point out doesn't have any such clause. You'd
certainly want waiver language like gwt-ext's license if you use it in a
commercial setting. While you'd probably win the reasonable argument that
your code simply called the library's interface and should be treated the
same as if normal java code called those same library interfaces (and not
suffer just because of the GWT compiler's translation to javascript). But
lawsuits are expensive, so if you were successful, you'd certainly make a
tempting target.

Re: SmartGWT?!

2010-01-14 Thread Sanjiv Jivan

As you mentioned in your previous mail, you are not a lawyer. So you can
come with theories and interpretations of LGPL and decide on use of a
library. I suspect you are a happy user of GWT and the widgets it provides
out of the box and that if you really wanted to use SmartGWT LGPL, you'd
consult the legal team of your company rather than speculation based on your
non lawyer interpretation of what really is pretty clearly spelled out in
the SmartGWT license file COPYING.html.

FYI Hibernate also adds the clarification on what they consider dynamic
linking and that use of Hibernate never affects the license of the users
code. https://www.hibernate.org/356.html
The SmartGWT license clarification was based on this. The use of Hibernate
is also not without caveats as you make it sound. Any application that users
Hibernate also runs into a gray area since due to dynamic proxying of
objects by Hibernate there is indeed modification involved. This is the very
reason that Hibernate too added the above license clarification.

If you are a user of Spring, Spring has a class
IdTransferringMergeEventListener
that extends org.hibernate.event.def.DefaultMergeEventListener and modifies
its runtime behavior.

Nobody is forcing anyone to use a free product - SmartGWT LGPL, and
similarly no favors are being done if anyone does chose to use the free
product.

This is getting off topic now. If anyone needs further LGPL clarifications
when using SmartGWT, feel free to post on the SmartGWT forum.

You're right. SmartGWT has modified/clarified their use of the LGPL
specifically to cover this point.

licensed under LGPL terms.
Yes, but Hibernate lives only on the server side, so doesn't suffer the
same problem. The GWT-LGPL issue is strictly a client-side problem and
this is why I'm happy to use Hibernate in my server code.

 Yes. And nobody here likes resource management. And Smart GWT is very

 for me, though I have to roll my eyes and sight deeply at least twice
 per hour, while implementing things.


It's quite easy to criticize a library, isn't it? Instead of making blanket
statements like these have you tried reporting the issues on the SmartGWT
forum, or file an issue in tracker. I don't recall any posts from you on the
SmartGWT forum, nor any issue in tracker. Given this, and your short history
on the GWT forum, its hard to tell if you're just inexperienced, haven't
read the extensive documentation, or have run into an issue but chose to
roll your eyes instead of reporting it.

SmartGWT is based on SmartClient, which has been around for some 8+ years
and it is very stable. No software is perfect, however if you take a step
back and have a look at the depth and breath of functionality it provides
you'll realize that how low the bug / functionality ratio is.

The SmartGWT tracker has only 34 open defects  :
http://code.google.com/p/smartgwt/issues/list

Try comparing this number with you favorite major library. If you have run
into an issue that is not yet reported, please do report it. Complaining
that a library is horrible, but still the best suited for you makes no
sense.

If you've already made up your mind that SmartGWT is not for you, thats
fine. But if you're want to be constructive, post your questions and issues
on the SmartGWT forum and you'll see that legitimate issues are resolved
promptly.

Re: Ext/GXT/ExtGWT v2.1.0 vs. SmartGWT v2.0

2010-02-16 Thread Sanjiv Jivan

mariyan,
The SmartGWT LGPL server side code can be as little or much depending on how
the developer codes it. Pro / EE handle the server side persistence so
there's minimal code to writ. With LGPL, the SmartGWT datasource protocol
simply passes the relevant information for various operations like fetch,
update, delete and insert. Thats it! From there on, the developer needs to
act on this information to service the operation request.

A fetch operation for example will pass the startRow, endRow and the
applications server side code needs to return data as XML, JSON or GWT-RPC
beans in response to this request. Similarly an insert or update operation
passes the data of the new record to the server. There's nothing inherent to
SmartGWT that requires more server side code. Infact its a very simple
protocol that imposes no extra overhead or server side requirements whether
you're using the Restful DataSource, or the GWT-RPC Datasource.

Have a look at this sample :
http://www.smartclient.com/smartgwt/showcase/#featured_restfulds

Hopefully this clarifies things. If you need some more information, there is
plenty of information in the Javadocs and also feel free to post on the
SmartGWT forum.

 in the smartclient's forum and all have problems with server integration.
 May be they are not experienced, may be it is unnessesery complicated or may
 be smart gwt is like that, because smart gwt pro/ee are better. Every thing
 is just bussines, and so it should be. I am just saying my personal opinion.

 Also, the fact that all of these features also apply to TreeGrids (eg
 frozen columns and full-row editing).

 Also, SmartGWT's data connector architecture and it's ability to
 support multiple caches on the same large data set, with independent
 search criteria, sort direction, etc.  This is needed for dozens of
 use cases involving large data sets, such as moving records from one
 category to another by drag and drop.  GXT's Store is extremely
 primitive by comparison and a lot of manual effort is required to
 achieve something like this:

 I have probably missed another 9 major grid features, and this only

 Bug report asking for RPC datasource
 http://code.google.com/p/smartgwt/issues/detail?id=303


Shawn,
The thread you point to is really old (2008). Since then, alius, one of the
SmartGWT users has come up with a good implementation of GwtRpcDataSource.
You can read this rather long thread (
http://forums.smartclient.com/showthread.php?t=4814 ), but all the
information you'll need is in there along with the GwtRpcDataSource
implementation.

The GwtRpcDataSource implementation is part of the smartgwt-extensions
project : http://code.google.com/p/smartgwt-extensions/


 I see there is an api but it states:

 Smart GWT supports declarative, XPath-based binding of visual
 components to any server capable of returning XML or JSON responses
 over HTTP, without the need for the 'Smart GWT server'.


Yes, this is true and there are a number of samples of this in the SmartGWT
Showcase.

http://www.smartclient.com/smartgwt/showcase/

Go to Data Integration--  XML, or JSON. You can even use Webservices / WSDL
based DataSources.



  A fetch operation for example will pass the startRow, endRow and the
  applications server side code needs to return data as XML, JSON or
 GWT-RPC
  beans in response to this request.
  : http://www.smartclient.com/smartgwt/showcase/#featured_restfulds

 Are there any examples using GWT-RPC (without the smart server)


 Sanjiv what you said and what the docs say seem to be different.  Can
 we really use GWT-RPC to get a bean back that can be used as a
 datasource?


Yes. sunnyl, another experienced SmartGWT has posted a complete standalone
project illustrating the use of GwtRpcDataSource here :
http://forums.smartclient.com/showthread.php?t=4814page=22

It's not fair to have these long discussion specific to SmartGWT on the GWT
forum. However its hard not to respond posts are made either intended to be
flame bait or from users who have not taken time to explore the product
features but make false assertions, or statements that are plain wrong.

Shawn, I would encourage you and any other user interested in SmartGWT to
post on the SmartGWT forum (
http://forums.smartclient.com/forumdisplay.php?f=14 )  - whether it be a
technical question, or about product features and capabilities. There's a
lot of SmartGWT introduction and related material even on my blog :

I've downloaded the 2.0 milestone 2 release.

Since there isn't yet the full set of documentation for 2.0, and I'm
new to GWT, and there are nice tutorials and books for 1.X, I'm
wondering if I can expect to use the 2.0ms2 release, to get started
with the tutorial and start prototyping new development using the 1.X

Also, what about smartgwt? Will the lates smartgwt 1.3 release work

Re: Query on Google Web Toolkit (GWT)

2009-12-06 Thread Sanjiv Jivan

Yozons Support on Gmail,
GWT is different things for different people. GWT is not only about use of
the widgets provided in the core library, or the use of GWT-RPC. These are
just one of numerous features that GWT provides. The ability to write GWT
application code in Java and IDE support is a huge productivity gain.

GWT-RPC is no doubt super convenient and easy to make RPC calls and share
classes on the client side and server side. However there are usecases that
SmartGWT / SmartClient transport protocol currently supports that are not
fully supported by GWT-RPC currently.

For example Transaction Queueing. I believe GWT is adding some batching
functionality as well and I'm looking forward to checking it out. More info
here :
http://www.jroller.com/sjivan/entry/introduction_to_smartgwt_enterprise_edition

Smart GWT also eliminates the need for having redundant Data Transfer Object
(DTO's) while at the same time having a rich domain model in a very elegant
way. More on this here :
http://www.jroller.com/sjivan/entry/solving_the_dto_dilemma

If you are happy with using GWT-RPC with DTO's or with Gilead, by all means
go for it. Infact there is a user extension for a GWTRPCDataSource provider
that allows you to use GWT-RPC as the DataSource provided for all Smart GWT
components.

As for intermixing of GWT widgets, obviously the goal is to provide 100%
interoperability with all other GWT libraries, include the widgets in GWT
itself. Infact Smart GWT does support interoperability with GWT widgets but
with some caveats like one should not place GWT widgets within a Smart GWT
container that is in turn within a GWT widget container. There are certain
contracts that the Smart GWT layout management expects which GWT widgets are
unaware of and are not able to participate in. Infact there will be similar
limitations with most third party libraries that provide their own layout
management schemes.

So to answer your question, Smart GWT is a library that allows you to write
applications using the GWT technology. Have a look at the features it
provides, feel free to ask any questions you have on the Smart GWT forum and
if you feel your application may benefit from it, you're free to use it. And
if not, just ignore it.

Yozons Support on Gmail,
Again, all the integration options were presented to you with
detailed information on the suitability and pros and cons of each approach.
Smart GWT (LGPL) also supports an XML / Json based Restful DataSource as
well as a community written GWT-RPC Datasource. It is now up to you, as the
product developer / architect to understand which approach works best for
your product and apply it. All the tools are available to you. Asking the
same question multiple times is really not going to help you get a better
answer. That's the responsibility of a product architect. If you, as the
product developer / architect think that a HashMap approach over GWT-RPC is
the most suitable for your product, then by all mean go for it.

It's only because our plans are for our product to be open source, and
while PRO may indeed work better out of the box, it creates licensing
conflicts to include a large commercial component that would affect both the
client and server code. The LGPL widgets definitely are winners.

Unfortunately, we have also noted a condescending attitude in many forum
replies, no doubt the result of dealing with so many newbies like myself who
are trying to figure it all out so we can make the most informed decision
possible.

The one downside I see for the product -- ironically enough -- is that it
seems to support so many options that it's much harder to evaluate and
discern what goes with what or how to put it all together if you are taking
a particular approach. It is great that it supports these myriad features
and options, don't get me wrong, but it is quite an experience trying to get
through all the material, all the various samples (many of which won't apply
to our situation), and trying to select which approach to take, wondering if
there are efficient trade-offs, etc. All these product variations (LGPL,
PRO, Power, EE), GWT-vs-JS libraries and documentation and samples, and
options may seem clear to you, but they most definitely are not to newbies.

We are having trouble finding a clear path for users like us who will be
using the GUI to interface with an established Java framework that has
public interfaces for all clients implemented with Java objects that
themselves handle all of the persistence, security enforcement, etc. so that
the GUI calls the same interfaces available to other non-browser systems
that may just want to use HTTP POST of name-value pairs, or perhaps SOAP, or
perhaps just posting XML/REST, iPhone/smartphone, etc.

There's even questions about how the LGPL version numbers match the EE
version numbers, how to test drive the latest PRO without having access to
the other features and documentation that only adds to our confusion, and
one feature we thought would be a huge boost, the visual builder, does not
appear to generate s'gwt code yet.

So that is why we investigate our options as we eval the new 2.0 widgets
and look forward to the new PRO 2.0 release to demo that incorporates them,
etc. After all, much of the discussion about the troubles of using DTOs may
be resolved using more flexible HashMaps interfaces which GWT-RPC can

Re: To smart GWT or not

2010-12-03 Thread Sanjiv Jivan

Jaroslav,
If you're happy with GWT that’s great but please do not make such vague and
baseless claims about Smart GWT. Legitimate bugs reported are fixed really
quickly and existing users can attest to this. Smart GWT currently has
around 42 open defects with a majority of them being low priority, and 16
enhancement requests ( http://code.google.com/p/smartgwt/issues/list ).
Considering the depth and breadth of features provided by the framework this
is a pretty low number of defects.

3 of the 7 issues that you filed were invalid, and 2 defects that were fixed
and the remaining 2 were marked WontFix since they were trivial pieces of
functionality that the user could easily implement.

Sorry that's quite absurd: SmartGWT is often introduced to solve

If your application is the kind we target - complex enterprise
applications which are used repeatedly and for significant lengths of
time - this provides a gigantic performance boost, and once-ever
download of cachable JavaScript files is a negligible factor.

Look at a deployed SmartGWT application and you've got users humming
along, ripping through the interface and nothing being downloaded
anymore because it's all cached. And everyone is getting fast
responses from the database because the Smart GWT framework is
minimizing database load.

The larger your application becomes, the more these benefits accrue.
And, by the time you've built an application with comparable
functionality with core GWT or another GWT-based framework, you're
going to be downloading the same size runtime as SmartGWT anyway.

Re: To smart GWT or not

2011-02-11 Thread Sanjiv Jivan

 have to determine the
features you need for your application, how much of it is provided by core
GWT or any other toolkit, the cost of building missing features in-house,
and compare it to the client and server integration features, support and
stability of Smart GWT and decide for yourself. I would recommend that you
read the SmartGWT quick start guide (
http://www.smartclient.com/releases/SmartGWT_Quick_Start_Guide.pdf ) if you
haven't already done so since it covers a lot of frequently asked questions
and features provided by the library.

Hope this addresses all your concerns :)

 Sanjiv,

 I know I am reopening this thread,  not to criticise Smart GWT, but want to
 give some feedback.

 First of all let me acknowledge that it is very good library with lot of
 cool and fantastic features. I experimented with it and liked it and
 planning to use it in one of my project.But I have some doubts and questions
 , which you I thought you will be best person to answer . Hence this mail.

 1. I am using  GWT and want to use some Smart GWT widgets in that
 application.But it looks like I have to include lot of Smart client JS file
 which size is about 2MB. Client need to download all these JS libs above our
 GWT compiled script. this become very huge download for client, Even I want
 to use  Smart GWT's grid , I realized that I have to include  almost
 everything except few small smart-client JS.So my question is why is so and
 what is work around for it?

 2.Second, smart-client scripts are not in compressed format (like GWT is).
 it is like GWT pretty format. If it is compressed then size of all script
 files will be reduced.

 3. My third question is - Why smart GWT is not written in GWT so that it
 can take advantage of GWT's optimised java script compiler.Smart GWT widget
 the can be extended by user to customize it. Right now Smart GWT widgets are
 just black box for developer.

 Theses are few question I had in mind., Over all features provided by smart
 GWT are great.

Hi,
You can work around this by placing the GWT 2.3 jars before the Smart GWT

in the next nightly build and the upcoming Smart GWT 2.5 release.

Let me know if you still have any problems.

Re: Massive increase in compile time with GWT 2.3

2011-05-18 Thread Sanjiv Jivan

Have you tried compilation using SSD? I'm my experience from last year,
SSD's were great for reads but terrible for writes and compilation of medium
to large projects actually took a fair bit longer on SSD's.

It's possible the newer SSD's have gotten better but I would recommend doing
some more research before making this expensive purchase with expectations
of significant compile time speed improvements.

On Wed, May 18, 2011 at 2:22 PM, Jeff Larsen larse...@gmail.com wrote:

 What is the purpose of the build?

 Is it to deploy the actual code to a production/test server or is it to
 enable some sort of selenium/webdriver test framework.

 If it is the latter, you could add -draftCompile which will not be highly
 obfuscated code, but it should be a quicker compile, especially with 48
 perms.

 You could also link up multiple computers to do distrubted permutation
 computations. Ray Cromwell had a talk about this at last year's IO.

 Depending on your budget, a SSD drive could potentially help you out a lot
 here too.

I believe RF is not meant to be used with lazy-loading if you don't also

That would be a pity. I thought the point of RF was dealing with ORM
entities without having to mind with stuff described here:
https://code.google.com/**webtoolkit/articles/using_gwt_**
with_hibernate.htmlhttps://code.google.com/webtoolkit/articles/using_gwt_with_hibernate.html
Actually, I thought that preventing lazy initialization exceptions was
the point of the with() method... I wonder why it exists if not for
that...

There are basically two choices when modelling synchronous APIs on top of
inherently asynchronous communications: get everything eagerly (with the
risk of retrieve the database as a whole) so that a getContactDetails()
always returns something, or get only what's requested (so that
getContactDetails() either returns data if it was requested, or returns
'null' otherwise).
RF falls in the second category (except that it doesn't apply it to
properties with simple values), and .with() is the way to request data
that wouldn't be loaded by default. By loaded here, we meant serialized
in the HTTP response, which is a different deal as to what can happen on
the server.

.with() has nothing to do with lazy-loading or lazy initialization
exceptions; it's only about what goes over the wire, and what's available
on the client-side.

or unproxy your objects rather than simply detaching them.

Would you advice the use of Gilead with RF for this?

I don't know Gilead (and I actually don't use JPA or JDO, but if I had to,
I wouldn't use lazy-loading, it causes much more burden than what it's
supposed to solve, it's not worth it, it's a lie, it's counterproductive
in the long run; JPA/JDO, like much enterprisey things, are
over-engineered and much too complicated to get them to work unless you're
an expert in the field).

 I experimented with JAXB to generate the java bean classes from the

 GWT, so there's no great way to view the attributes of the class in

 I imagine people have done similar things before.

Re: Convert Java bean Object to JSON in GWT 2.4

2011-10-13 Thread Sanjiv Jivan

Gere,
Can you elaborate what you're trying to do here? What kind of datasource are
you using in SmartGWT and where are you trying to convert the beans to JSON?
If you're using RestDataSource then you're probably converting your beans to
JSON on the server side and for this you can use a library like XStream or
FlexJSON ( http://flexjson.sourceforge.net/ ).  As Gal Dolber mentions,
piriti can be used to convert beans to JSON on the client side but this
might not be what you're looking for.

Use of RequestFactory is not required or appropriate when working with Smart
GWT datasources.

Re: Client/Server communication. GWT-RPC ? GIlead ? Dozer ? RequestFactory ?

 I'm just about to start a major web  app project (rewriting the main

 business app with a lot of tabular  data and information. But still I have
 some concerns.

- GWT-RPC was one of the reason, I chose GWT in the past because of
the magic of using (almost) the same objects on the server and client
sides. To cope with the serialization and HIbenrante Lazy loading issues,
we 've been using 2 strategies :
   - 1/ A modified version  of Dozer (powerful but needs tweaking)
   used to transtype HIbernate objects into a dedicated DTO layer
   - 2/ Directly buidling dedicated objects for GWT (infact on this
   project we even use the same genric structure for entities, a kind of
   enhanced map of properties with an additional type and id attributes.
- Today there is a kind of fog around these questions: GILEAD is not
maintained any more, the new RequestFactory API seems awkard to me
(especially with all these loose conventions)

 So in a nutshell what guys do you recommend for client / server
 communication in GWT today ?

Re: GWT 2.4 DevMode almost always hangs at Checking for updates

2012-11-13 Thread Sanjiv Jivan

It found the option : -XdisableUpdateCheck

The reason I need to disable this is because of classloader issues I'm
running into with a custom PreferencesFactory implementation that our app
uses. The DevMode check for update initializes the Preferences class
outside the web app context class loader and the Preferences class uses a
static final member variable for the factory.

Re: How get widget width, after it's drawed ?

Since you're using SmartGWT, use addDrawHandler(..). The callback gets
invoked after the widget is rendered.

vLayout.addDrawHandler(new DrawHandler() {
@Override
public void onDraw(DrawEvent drawEvent) {
..
}
})

Re: Is it possible to create screens at runtime?

2013-03-05 Thread Sanjiv Jivan

Hi Thiago,

With SmartGWT (Pro and above), you can save screen definitions in XML and
load them at runtime:

http://www.smartclient.com/smartgwtee/javadoc/com/smartgwt/client/rpc/RPCManager.html#loadScreen(java.lang.String
,
com.smartgwt.client.rpc.LoadScreenCallback, java.lang.String[])

So you could build some kind of editing interface that allows new screens
to be designed, then save them to a database or file in XML, and be able to
load them at runtime using loadScreen().

You can also dynamically generate XML DataSource definitions, which contain
data validators and other business rule definitions, enforced on both
client and server:

http://www.smartclient.com/smartgwtee/server/javadoc/com/isomorphic/datasource/DataSource.html#addDynamicDSGenerator(com.isomorphic.datasource.DynamicDSGenerator

There are samples of using XML screen definitions in the SmartGWT EE
Showcase under the folder Component XML, but you have to download a 4.0
build to get them:

The Component XML overview explains how to provide dynamic Component XML
that's stored in a DB - see Dynamic Component XML:

[gwt-contrib] slow startup of hosted mode

2009-06-05 Thread Sanjiv Jivan


Hi,
Some of the users of SmartGWT have reported slow startup in hosted
mode. A user narrowed down the problem to the following call in
StandardLinkerContext.

outFile.lastModified() = artifact.getLastModified()

When changed to outFile.lastModified()  artifact.getLastModified(),
the startup is normal.

http://code.google.com/p/google-web-toolkit/issues/detail?id=3700

Can you guys comment on whether this is a valid change?

One other thing that I noticed was that when I moved the resources
(skin images) from the public path of my main module (SmartGwt), to
a secondary module (SmartGwtXXXSkin), and the user is required to
inherit both these modules, the hosted mode startup slowed down a fair
bit compared to when he inherited only one module that also had the
skins resources. Does this ring a bell? If not, I'll try to dig a
little deeper into this and provide more information.

Thanks,
Sanjiv

[gwt-contrib] JSNI warnings in OOPHM

[WARN] JSNI method 'fireOnModuleLoadStart' returned a value of type
boolean but was declared void; it should not have returned a value at
all
JSNI method '@com.google.gwt.user.client.impl.HistoryImpl::setToken

along with a whole bunch of them from my code

I'm pretty sure that the JSOHelper.setAttribute(..) method is not

 Did you build the FF3.5 plugin from source with make BROWSER=ff35 and
 install prebuild/oophm-xpcom-ff35.xpi?  What is currently checked in as
 prebuilt (and available from the UsingOOPHM wiki page) does not support
 FF3.5.

See the

(linked from UsingOOPHM) with details on this issue. I assume you are
using Eclipse, in which case Eclipse helpfully adds the -XstartOnFirstThread
flag for you when it sees the SWT libraries on your classpath, which is
required for SWT apps but breaks Swing apps.

up with particularly useful information. I use IntelliJ and have logged an

[gwt-contrib] OOPHM performance

2009-08-21 Thread Sanjiv Jivan


Hi,
I've only recently started working with OOPHM and it looks great. I
observed that the performance / responsiveness when running the
SmartGWT showcase with OOPHM seems to be much better (and close to web
mode) with OOPHM compared to the GWT 1.7 hosted mode. Is there any
technical explanation for this? In particular can one expect
performance improvements with JSNI code and OOMPH over its
predecessor?

It could very well be something in my mind in which case I'll try to
benchmark more concrete evidence.

within the method) will benefit from browser JS engine speedups.
Please correct me if I'm wrong.

IntelliJ 9 has added support for remote JavaScript debugging so that
you can set breakpoints and step through Javascript code from within
the IDE in a way identical to debugging Java. They do this via a FF
plugin. Do you guys have a sense of the technical feasibility of them
supporting breakpoints within JSNI code when running with OOPHM?
IntelliJ alread has excellent GWT support. I realize I'm light on the
details but it would be nice to know if its not possible or it
might be possible based on your indepth knowledge of how OOPHM works.
Maybe its just a pipe dream :)

Thanks,
Sanjiv

 Sanjiv,
 My experience with oophm has been that it simply has different performance
 than the old hosted-mode implementation. It can be faster in some cases,
 because (it seems) the marshalling code between Java and Javascript is less
 complex. On the other hand, it can sometimes be a lot *slower*, because all
 Java-Javascript transitions go over the network (which is usually
 localhost, but it still creates extra overhead). This seems to be worst in
 cases where you make a large number of fine-grained calls into the DOM (or
 other native constructs) from Java code.

 Cheers,

  Hi,
  I've only recently started working with OOPHM and it looks great. I
  observed that the performance / responsiveness when running the
  SmartGWT showcase with OOPHM seems to be much better (and close to web
  mode) with OOPHM compared to the GWT 1.7 hosted mode. Is there any
  technical explanation for this? In particular can one expect
  performance improvements with JSNI code and OOMPH over its
  predecessor?

  It could very well be something in my mind in which case I'll try to
  benchmark more concrete evidence.

 There have been some discussions about possibilities, but no real plans as
 yet.  My guess is it would be possible but a huge amount of work, especially
 doing it cross-browser and cross-platform.


For the immediate future I was more thinking about the possibility of
IntelliJ adding support for JSNI debugging with the current OOPHM
implementation. IntelliJ's remote Javascript debugging works with FF only
(via their plugin) and the ability to debug even only with FF and OOMPH will
be a huge benefit since FF is available on all platforms. As you state, the
JSNI code runs within the browser so one should be able to use their
debugger to connect to the remote Javascript running in OOPHM. The issue is
whether they will be able to obtain the information to map the line numbers
and breakpoints in the JSNI application code to the actual JSNI code running
in the browser. I was wondering this information was something that can
currently be found using the OOPHM FF plugin, or would even this involve a
huge amount of work?

Thanks,
Sanjiv

Re: [gwt-contrib] Add support for launching a default browser from Swing interface

2009-11-29 Thread Sanjiv Jivan

Can the default launch URL use the IP instead of localhost? I use VMWare on
my OSX machine and often access the dev mode URL from a Windows VM using IE
for testing purposes. Currently I need to manually replace localhost with
the machine IP in the URL. It's not a big deal but will add a little
convenience if there are no downsides to using IP instead of localhost.

 Reviewers: Ray Ryan, bruce,

 Description:
 This patch adds support for launching the user's default browser using
 several methods.  This facility is then used for HelpInfo links in the
 logger detail messages (falling back to the old method of using the
 Swing HTML panel if none work), including the launch browser message.
 This won't launch automatically (there are still too many variables,
 such as wanting to launch a different browser or a particular profile),
 but it will make it much easier to launch if the default is what they
 want.  It will also give a much better experience for clicking other
 HelpInfo links, such as the upgrade message.

 BrowserLauncher includes a main method that takes one or more URLs, so
 you can run it with an arg of http://www.google.com, for example, to
 make sure it works independent of the Swing logger.  I have tested it on
 Linux with JDK 1.5 and 1.6 (which is significant since 1.6 adds a
 platform-independent way to launch the browser) -- please test on other
 platforms and make sure it works properly.

Re: [gwt-contrib] debugging of JSNI code

2010-02-16 Thread Sanjiv Jivan

Are you saying that the JS debugger automatically triggers even today when
one tries to step into a JSNI method?

I know that manually adding a debugger; command within JSNI code will
trigger the JS debugger, and I also have a helper GWT JSNI method called
SC.debugger() which I can add anywhere in my GWT code but what I was hoping
for is the debugger command automatically be issued by the GWT plugin when
one tries to step into JSNI code from my Java IDE.

If this is already the default behavior, then shame on me :) I can try it
out later today as well but I don't recollect seeing this behavior.

  Hi,
 A while ago I had asked the possibility of being able to step through JSNI
 code when running in hosted mode as IDE's like IntelliJ support remote
 Javascript debugging from within the IDE itself much like Java debugging. I
 was informed that currently the only debug information collected was the
 line number at the boundary of the JSNI method and I can see this when
 running through a JS debugger.

 It would be great if one day this feature can be added however for now I
 was wondering how easy / feasible it would be to dynamically trigger the JS
 command debugger; when they user does a Step Into from the Java
 debugger. The newer versions of Safari has a very good debugger that
 performs well. The hosted mode plugin for Safari can have the Enable Script
 Debugging setting turned on for the hosted mode session. Firebug also
 responds to the debugger command. Similarly the IE Visual Studio /
 Javascript debugger is launched if installed when the debugger command is
 encountered.

 Any comments / thoughts on this?

 Thanks,
 Sanjiv

[gwt-contrib] $entry and wrapping result as Object in hosted mode

2010-04-10 Thread Sanjiv Jivan

I've run into an issue where I have a JSNI callback function wrapped within
$entry so that exceptions raised by the GWT callback method are propagated
correctly through the GWT exception handling mechanism.

The issue I'm seeing is that in hosted mode when the function that $entry
wraps is returns a boolean 'false'  the apply method below gets called via
$entry(..) and it wraps the boolean false value as Object(false). As a
result when this value is passed to external JS is treated as true i,e. if(
Object(false) ) { .. } evaluates as true.

Impl.java:144

  private static native Object apply(Object jsFunction, Object thisObj,
  Object arguments) /*-{
if (@com.google.gwt.core.client.GWT::isScript()()) {
  return jsFunction.apply(thisObj, arguments);
} else {
  _ = jsFunction.apply(thisObj, arguments);
  if (_ != null) {
// Wrap for hosted mode
_ = Object(_);
  }
  return _;
}
  }-*/;

What is the rationale for this wrapping as Object(..) in hosted mode? And
can you suggest a workaround for this usecase?

Thanks,
Sanjiv

Re: [gwt-contrib] $entry and wrapping result as Object in hosted mode

2010-04-11 Thread Sanjiv Jivan

Thank's for the tip Ray. Unfortunately I'm not seeing the desired results
with Boolean, while Number works fine. However .valueOf() does return the
correct result.

Boolean.apply(null, [Object(false)])
 true
 Number.apply(null, [Object(5)])
 5
 (Object(false)).valueOf()
 false
 (Object(true)).valueOf()
 true
 (Object(5)).valueOf()
5
 (Object(foobar)).valueOf()
 foobar
Object(foobar)
String


 So I have altered the debox function to call valueOf() instead of apply(..)
and it appears to be working fine with my limited testing.

// no longer need to pass typeCast arg
$debox = function(val, typeCast) {
return @com.google.gwt.core.client.GWT::isScript()() ? val : function()
{
var v = val.apply(this, arguments);
//return typeCast.apply(null, v == undefined ? [] : [v]);
return v == null ? null : v.valueOf();
}};

I'll only be calling debox(..) for functions that have a Javascript
primitive return types including String type. The reason for applying it to
a String as well is because of this issue :
http://code.google.com/p/google-web-toolkit/issues/detail?id=4301

Let me know your thoughts..

Re: [gwt-contrib] $entry and wrapping result as Object in hosted mode

2010-04-11 Thread Sanjiv Jivan

I had originally tried on Safari 4.0.4 on OSX but just tried on Chrome (win)
and FF and got the same results.

So what you have is fine, the type returned on calling Boolean.apply(null,
[Object(true)] ) is indeed boolean.

The issue is that the value returned is incorrect when the original val is
false.

So try x = Object(false) and then echo the value of y. I'm getting a return
value of boolean 'true' instead of boolean 'false'

[gwt-contrib] GWTTestCase and user defined linker

2010-11-19 Thread Sanjiv Jivan

Hi,
I have a test class that extends GWTTestCase and returns a certain module
name. This test module inherits a library module that has a user defined
linker via define-linker and add-linker. When I run the testcase in debug
mode I notice that the user defined linker is not invoked. Running the same
module as a GWT app in hosted mode triggers the linker. If this is not the
expected behavior, please let me know and I'll try to create a simplified
testcase.

You mean going the -noserver route? I like the convenience of starting the
entire app within Jetty in dev mode. How about allowing a descriptor that
specifies the jars required by GWT?

Most apps probably require at most a handful of third-party GWT jars but
have a large number of jars required by the server so the overhead of
scanning all jars in the classpath is quite undesirable.
