"Java Is Dead, Long Live Java!" – The Future of Java

"Java Is Dead, Long Live Java!" – The Future of Java — 'Because of its prominence,' writes Bryan Taylor, 'Java gets a lot of attention and with it much criticism, some of it valid.'

In this column he takes a view of where Java is going to go in the next year or two as these ideas gain traction. Trackback URL :  Click Here

Deadly Combination

Yes, Deadly combination!! It doesn't means that there would some super stars of the film who would go the devil place and finish him. No No !! I am talking about the deadly combination used in the development of the web sites. I am talking about the tools used for the Java development. Any guesses so far.... Yes, they are Struts2 , Spring , and Hibernate I am currently working all these tools. I am amazed to see the power of all the three technologies and how they makes the life of a developer like me, so easy. All of three would make your project a huge success. Now talking about Struts2 ... It is great framework with the inbuilt Ajax tags that would help many developers. Many new features of the struts2 are marvelous. Hibernate ... I already told in my last post about this. Hibernate would provide you a greater facility for your data persistence. its in built architecture that is fully object oriented which makes it a powerful tool. And yes, not to forget about the HQL (Hi

Hibernate Rocks

After few days working on hibernate I found it very interesting and useful tool for the developers. It allows to handle code more efficiently while working on the database part. Since I am new to it I don't know all the features of the hibernate, but yes the features that I had used are tremendous and the code is more reliable and efficient. All the connection management is handled by it. And specially the mapping files which allows us to connect to the database I enjoyed working with it and hopes it will provide more features in the future.

Changing default style of <s:actionerror/> / <s:actionmessage/> tag

In struts 2 when you put <s:actionerror /> tag it displays the errors in the following way: <ul> <li>error 1</li> <li>error 2</li> </ul> But sometimes it seems to be very ugly when displaying the dot (.) in the action errors or action messages Below is a normal code that displays the tags in your customized way. You can specify your own css for this <s:if test="hasActionErrors()"> <s:iterator value="actionErrors"> <span class="errorMessage"><s:property escape="false" /> </span> </s:iterator> </s:if> Alternatively you can change the file in the "/template/simple/actionerror.ftl” and put it in the /web-directory/struts/simple if using simple theme Similar for <s:actionmessage /> tag.
