Spring in Action may be a good book to start with.

Hi,

Caused by: java.lang.ClassNotFoundException: org.hibernate.cfg.AnnotationConfiguration

The basic cause of your error is a ClassNotFoundException. The above class is present in hibernate-annotations jar.
You can download it from here

Hi,

You need to implement the HasKeyDownHandlers interface in order to add the key down handler capability to your vertical panel.

The line where SOP is written itself might not be getting executed. Try Debugging that line of code where you have written SOP.

Yes I did like the movie, it was awesome.
Well my question is something weird, I guess i have to figure out a work around for situation

Can we have an AOP method interceptor itself being intercepted by some other AOP interceptor class?

Hi,
I read an article on GWT serialization; GWT - Serialization strategy is not as sophisticated as Java
It says that the GWT serialization is not as sophisticated as that of Java. In java, as per my knowledge if I have a list of objects and if a particular object is repeated the object data is serialized only the first time , the next time if the same object is encountered only the reference of the object is passed.

My question is if the Gwt serialization is not sophisticated does that imply that the object data may be serialized many times. If such is the case I have to improvise on my performance using some other techniques while passing same objects to the server.

Thanks a ton,

I used the Jboss 4.2.2 GA for my deployment it works fine but still it shows the conflict while loading gwt-user.jar and jeee.jar saying that the conflict is with the javax.servlet.Servlet class
and hence these jars have not been loaded

What do you suggest should i continue with this jboss or should i switch to 6.0

Hi,

I am having an application which uses gwt at the client side and using the dispatcher servlet i have done the mapping for processing gwt requests. The GWT requests are Rpc requests and hence I am getting an exception on the jboss console which says
10:37:53,948 ERROR [[ibe]] Servlet.service() for servlet ibe threw exception javax.servlet.ServletException: non-HTTP request or response at javax.servlet.http.HttpServlet.service(HttpServlet.java:715) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:235) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:190) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:92) at org.jboss.web.tomcat.security.SecurityContextEstablishmentValve.process(SecurityContextEstablishmentValve.java:126) at org.jboss.web.tomcat.security.SecurityContextEstablishmentValve.invoke(SecurityContextEstablishmentValve.java:70) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:158) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:330) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:829) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:598) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447) at java.lang.Thread.run(Unknown Source)

But if i run a simple gwt sample application i do not get this error.

Please suggest what should be done.

Check this image. This is what I want to achieve.

Hey thanks for the reply,

Actually if you see in the link the sliding pointer is only one so you can select only one value. I want to have a selection of range of values.
For example, I am supposed to display set of medicines for different age groups say 12 - 30 and 30 - 50 the min age is 5 and max is 105
The slider bar should have sliding facility at both endpoints i.e user should be able to select any range of values and not a single value.

I am using com.google.gwt.gen2.picker.client.SliderBar.

Hi,

I wanted to have a slider bar for selecting a range of values between minimum and maximum. For example if min value is 1 and max is 100 I should be able to select range from 72 to 91. For this purpose a I tried to use a slider bar but since it provides only one value and not a range of values, it doesn't serve the purpose.

Does anyone know of any Slider bar in GWT or any other external library support for this dual ended slider bar?

Hi Krishna,
Welcome to Java Ranch!!!

In extension to what Anupam said.. ...

What is static? Static simply means one copy per class. ie. Static variable is part of a class and not of an object of that class. N number of objects of the class refer to the same variable when it is declared as static.

A non static variable is a part of the object of that class. And to access the variable you need to create an object and that object will have its own copy. When you create another object it will have another copy.

So when you try to access static variable from a non static context you will get errors?
