How to create a Data Services ES2 application by manually creating Java server-side classes

Did you know that you can use LiveCycle Data Services ES2 to manage data located in a relational database? That’s right, using Data Services ES2, you can automate data synchronization between an Adobe Flex client application and a middle tier. As part of creating a Data Services ES2 application, you can create server-side classes that contain Java DAO application logic. If you are wondering how to do this, check out the Creating data management applications by manually creating Java server-side classes article.

LiveCycle Data Services 3.1 available

LiveCycle Data Services ES2 version 3.1 is now available for download. This release aligns with Flash Builder 4 and Flex 4, improves model-driven development and offline data management, provides wider platform support, and fixes many bugs.

Documentation on model-driven applications now provides tutorial-style content and new information on building offline applications and customizing server-side and client-side functionality.

Validating Guide object data using references to ActionScript validators

I learned a little trick from the LiveCycle software verification team regarding a neat way to validate the data users enter into objects on a Guide. If you are interested, you can check out the information in Adobe Cookbooks.

See the Guides section of the cookbook.

Have a nice day.

Tip for working with the LiveCycle ES2 Email component

You can use the LiveCycle ES2 Email component to enable your processes to send email messages, as shown in the following illustration.

When using the Email component, you specify typical values such as the SMTP server, the user name, and password. The Email component is straightforward, especially if you are used to working with TCPIP servers and the SMTP and POP3 protocols. (For more, see the Email topic in Application Development Using LiveCycle Workbench ES2.)

Unfortunately, when working with the Email component, you may encounter a situation that can lead to some frustration. When testing your process in Workbench ES2, an exception may be thrown when the Email component attempts to send an email message. The LiveCycle ES2 log file displays the following information:

2010-04-12 13:31:46,406 ERROR [com.adobe.idp.workflow.dsc.invoker.WorkflowDSCInvoker] An exception was thrown with name javax.mail.MessagingException message:Could not connect to SMTP host: myserver, port: 25 while invoking service EmailService and operation send and no fault routes were found to be configured.

This may lead you to triple check your Email server configuration settings, rebuild your processes, test them over and over again, and so forth. If this occurs, check your anti-virus software, it may be blocking port 25. Once the anti-virus software lets you route messages through port 25, your LiveCycle ES2 processes that use the Email component will work nicely (assuming that all other settings are valid).
