GWT meets Flex: Java API for Flex

Hello people,
I m somedays away to release the version 2.1 of gwt4air. gwt4air is an open source project based on gwt (http://code.google.com/webtoolkit/) and provides a Java API to different platform where Java is not the primary language.
Version 2.0 added among other features support for Adobe AIR, Alive PDF, Pure PDF, Aswing and other GWT based UI libraries like EXT-GWT
With version 2.1 i added support for Flex(AIR and Browser). The goal of this approach is to make it easy for Java Developers to switch to Flex be leveraging a swing like API. But also to present an alternative to the classical Flex developement. The overall idea behind this is described here:
http://code.google.com/p/gwt4air/wiki/Beginn
A demo application ca be found here: http://gwt4air.appspot.com/
The application contains around 100 demos with source code illustrating the use of the api.
I ve tried to keep the API similar to the AS3 api so one could easely switch from AS3 to Java and vice versa
Note that this flex applicaton is entirely written in Java using gwt4air. No AS3 no MXML.
The application is still in alpha stage so please expect some errors.
The project home is located at:
http://code.google.com/p/gwt4air/
I m looking forward to hear what you think about this idea. Any inputs (good or bad) is really welcome
Help me make this an even better tool.
It s about time that Flex rocks the GWT world
cheers,
Alain

It looks like those genius @google are also thinking about a Java(GWT) API for Flash .

Glad to see that i m not a fool
Or alteast not the only fool that believe combining Java and Flash/Flex is a potent mix.

Java API for Adobe Flex(AIR and Browser)

Hello Community,
Sometime ago i started the project located at: : http://code.google.com/p/gwt4air/ , wich primary goal was to bring another approach on writing AIR application by providing a Java API for the AIR API. On top of that i added support for PDF and Excel generation using Java.
I m glad to announce that the project will now add support for the Flex Framework
I wrote a post about it on the main page.
The Idea behind it is to give Java Developers a more simple way to write Flex Application by leaveraing a swing like API.
I hope this project will be a good alternative to the MXML+ ActionScript approach and looking for people willing to join the project.
Regards,
Alain

Good question, I'd like to know this myself. 4.5 has a huge number of changes since 4.0.

'Public' Flex Java API licensing

Hi all,
I would like to use the MessageBroker and AsyncMessage classes from Flex Java API to publish messages to a Flex destination from Java classes.
The library with this API comes in the LiveCycle Data Services release but when i look at this API, it says clear is 'Public'.
How public is it? Can i use those classes freely for my production application? Is there any license restriction? Same license as for Live Cycle Services?
I need to know to decide what design i will use to connect or Flex client with our java server, so is really urgent.
Thanks,
Dani.

Looks like things have changed a bit since last week when I posted.
With the announcement yesterday of BlazeDS (scheduled for release 2008), it seems the libraries mentioned will be available under the LGPL v3, so I believe you may be able to redistribute them (unmodified and probably as a separate installer/archive) under the terms of the LGPL.
http://labs.adobe.com/technologies/blazeds/
It sounds like there will be some features not included in the OSS version of Data Services, but from reading the FAQ it seems that the messaging API you mentioned will be included in the LGPL licenced version.

Java API for running entire ".sql" files on a remote DB ( mySQL or Oracle)?

Hi,
Would anyone happen to know if there's a java API for executing entire ".sql" files (containing several different SQL commands), on a remote database server ?
It's enough if the API works with MySQL and/or Oracle.
Just to demonstrate what i'm looking for:
Suppose you've created sql file "c:/test.sql" with several script lines:
-- test.sql:
insert into TABLE1 values(3,3);
insert into TABLE1 values(5,5);
create table TABLE2 (name VARCHER) ENGINE innoDB; -- MYSQL specific
Then the java API should look something like:
// Dummy java code:
String driver="com.mysql.jdbc.Driver";
String url= "jdbc:mysql://localhost:3306/myDb";
SomeAPI.executeScriptFile( "c:/test.sql", driver, url);
Thanks.

No such a API, but it's easy to parse all sqls in a file, then run those command:
For instance:
import java.sql.*;
import java.util.Properties;
/* A demo show how to load some sql statements. */
public class testSQL {
private final static Object[] getSQLStatements(java.util.Vector v) {
Object[] statements = new Object[v.size()];
Object temp;
for (int i = 0; i < v.size(); i++) {
temp = v.elementAt(i);
if (temp instanceof java.util.Vector)
statements[i] = getSQLStatements( (java.util.Vector) temp);
else
statements[i] = temp;
return statements;

Image not displayed in pdf generated using Java API for Forms service

Hi,
I am creating a pdf document using Java API for Forms Service.
I am able to generate the pdf but the images are not visible in the generated pdf.
The image relative path is coming in the xml as defined below. The images are stored dynamically in the Livecycle repository each time a request is fired with unique name before the xml is generated.
<imageURI xfa:contentType="image/png" href="../Images/logo.png"></imageURI>
Not sure if I need to specify specify specific URI values that are required to render a form with image.
The same thing is working when I generate pdf document using Java API for Output Service.
As, I need to generate interactive form, I have to use Forms service to generate pdfs.
Any help will be highly appreciated.
Thanks.

Below is the code snippet:
            //Create a FormsServiceClient object
            FormsServiceClient formsClient = new FormsServiceClient(myFactory);
            //Specify URI values that are required to render a form
            URLSpec uriValues = new URLSpec();
                              // Template location contains the whole rpository path for the form
            uriValues.setContentRootURI(templateLocation);
           // The base URL where form resources such as images and scripts are located. Whole Image path is passed in BaseUrl in the http format.
                  String baseLocation = repositoryPath.concat(serviceName).concat(imagesPath);
                              uriValues.setBaseURL(baseLocation);
            // Set run-time options using a PDFFormRenderSpec instance
            PDFFormRenderSpec pdfFormRenderSpec = new PDFFormRenderSpec();
            pdfFormRenderSpec.setCacheEnabled(new Boolean(true));
            pdfFormRenderSpec.setAcrobatVersion(com.adobe.livecycle.formsservice.client.AcrobatVersio n.Acrobat_8);
                              //Invoke the renderPDFForm method and write the
            //results to a client web browser
            String tempTemplateName =templateName;
            FormsResult formOut = formsClient.renderPDFForm(tempTemplateName,
                                          inXMDataTransformed,pdfFormRenderSpec,uriValues,null);
            //Create a Document object that stores form data
            Document outputDocument = formOut.getOutputContent();
            InputStream inputStream = outputDocument.getInputStream();

EWS JAVA API for availability is giving only 10 suggested times in a particular day

I'm using EWS JAVA API for seeing the availability of contacts who had shared their calender with me. Here in the suggested timings, I can able to see only 10 suggested timings even though there can be more than 10 suggested slots.
I would like to check is there any limit on suggested times ?
API is also giving quality of timing like "Good", "Excellent" on what basis this is decided ?

You can specify the maximum number of suggestions per day using the MaximumResultsByDay parameter (http://msdn.microsoft.com/en-us/library/office/aa565641(v=exchg.150).aspx).
The quality is determined based on how many attendees are available and is influenced by the GoodThreshold:

How to use java api for function activity in embed oracle workflow?

because i can't install standalone oracle workflow successfully.
pls tell me how to use java api for function activity in embed oracle workflow?
are there some patch or pulg-in package?

The Java Function Activity Agent is not certified for Oracle Workflow embedded in Oracle Applications. Installing standalone workflow should be a lot easier than what you have found, although it looks like you did hit a Pentium 4 issue with the Oracle Universal Installer. I suggest you contact Oracle Support or Oracle Consulting for assistance.

Java API for Webchannel 7.0

Hello,
for the ISA 4.0 we had the API of the java classes. Is there something like this for CRM 7.0.
Best regards,
Nils

Hi Nils,
Follow below steps.
Yes you can get it from service market place.
Follow below steps.
1) Log in to service market place.
2) Click on "Download" Tab
3) On Left side click on SAP Software Distribution Center -->Download > Support Packages and Patches> Entry By Application Group.
4) On Right side. Support Packages and Patches>SAP Application Components> SAP CRM> SAP CRM 2007> Entry by Component--> CRM Application Server Java
5) Click on "SAP SHARED JAVA COMPONENTS"
6) From Below screen click on "Download" tab and Download "SAPSHRJAVxx_x-xxxxxxxx.SCA" file.
7) Open "SAPSHRJAVxx_x-xxxxxxxx.SCA" file by "WINRAR" and unzip on your local laptop.
8) After unzip you will get several zip files under folder "BUILDARCHIVES"
9) Find "crmshrjavadoc" file inside folder "BUILDARCHIVES"
10) Unzip "crmshrjavadoc" file and you will get "javadoc.ppa" file
11) Rename "Javadoc.ppa" file to "Javadoc.zip"
12) Unzip "Javadoc.zip" file which we just rename in step 11.
13) you will get folder "Docs". This folder contain actual "javadoc.zip" file
14) Unzip above file and you will get Java API Documents for ISA 5.0 or ISA 6.0 or ISA 7.0 depends on "SAPSHRJAVxx_x-xxxxxxxx.SCA" version and SP level.
I just got ISA Java Doc by following above steps. It looks 14 step but once you download SCA file it will take only 2-3 minutes.
I am sure you will get Standard Java API for ISA just like ISA 4.0
Please let me know if you face any problem.
Also Visit this ECmmerce 6.0 Java API needed
Let me know if you face any error or problem.

Any Java API for dumping database?

As far as I know, the normal way to dump a database is to execute some command on the console.
Is there any Java API for dumping a database, so that the operation can be wrapped in the code?
The database system that I'm using is MySQL. Please help. Thanks!

By "dumping a database" I mean exporting data in the database into a text file, as a backup, that can be used when restoring the database. For example, in MySQL, I can run "mysqldump" on the command line to dump the database into a file.
So far I still have no idea how to do this using JDBC or any other Java API. Please help!

Question about Java API for XML schema?

Hello, everyone!
I am looking for a java api for XML schema. I hope the API is capable for parsing the structure of element
or complextype declarations in XML schema. So for example, if I specify a name of an element or
complextype defined in a schema, the name, dataype and other constraints of contained child elements can be returned.
Does anyone know if there exists such a paser?
Thanks very much!

Essbase Java Api for Filters

Hi all,I am using Java Apis for Essbase 7.1. I am using following Api for Database Filters to get the "Access Level". IEssCube.IEssSecurityFilter.getAccess()Gets the default filter access level. However the doumentation does not provide any information about the value returned by this Api and its meaning.Please can you tell what each integer value returned by this Api represents..Thanks.

I believe the values are documented in IEssCube.EEssCubeAccess.Be aware the security filter class is marked 'for future use' in the docs:The IEssSecurityFilter is cube security filter. (FOR FUTURE USE). That may mean it is not fully tested or perhaps not even fully implemented.Tim TowApplied OLAP, Inc

Paint Tools API For flex

Hello Flex Friends! I was wondering if anyone knew of a good
(free preferably ) API that has the basic paint options that you
could find in MS Paint (or more). I know how to make a rectangle,
and circle, and draw lines and all that jazz, I am looking more on
how to create spray paint cans, and complex erasing etc.
I have seen
http://www.flexibleexperiments.com/Flex/PrimitiveExplorer/Flex2PrimitiveExplorer.html
and that has been the best so far. Any additional thoughts would be
greatly appreciated. Thanks!

Thanks JeffHourser this looks really cool and is deffineatly
a resource I will keep in my bag, however this is a bit complex for
our current needs. What I am really interested in is an API that
can do:
Lines
Basic Shapes
fills
spray paint (like mspaints)
other basic art tools
I know i can do most of these using flex's built in API for
drawing, however, it seems that there is no point in recreating the
wheel if someone else has already done it.
Thanks!
