[appengine-java] Workaround for like keyword in JDOQL
Hi All, I am developing a resource allocation application in GAE with Java. Since there is no like keyword in JDOQL, I am unable to do search in database based on a keyword. For example, I want to list all the employees who have 'ash' word in their name. I have already wasted 3 days due to this problem. So please suggest me some workaround to achieve above this goal. Thanks in advance. Regards, Piyush Jain -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

Re: [appengine-java] Instant messenger
Thanks Stevko for quick reply. Your suggestions are really helpful to start with. I have decided to select servlets for writing code, GWT for creating GUI as you suggested. But i am still confused how to authenticate google users , facebook users ,yahoo users etc. Is there any authentication API ? I am just collecting requirements at this moment. Once all the requirements freezes, i will start working on code and GUI. If you have any suggestion please let me know. Hope you will help me. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
