  Hi Folks, I have some data in one of my mysql table stored as utf8. The data is some japanese text. I need to export it to excel. Could you tell how to do it? Exporting by SELECT ...

• Need to recover local changes overwritten by p4 revert

  - by Nayn

  Hi, I had a pending changelist in my workspace. By mistake I reverted one of the files by reverting to depot. Eclipse wiped off the local history. I am not sure if perforce keeps any history for pending changelists. Could someone tell me if it is possible to recover such file. Thanks Nayn

• When should one create interface for request or response for messaging within the application

  - by Nayn

  Hi, I want to know if there is any need to create interface for request/response objects. I know ServletRequest is an interface. I see request/response as simple pojo, where having some members to hold data and getter/setters would suffice. The processing of such data could be delegated to external utility classes. Does anyone have specific inputs on this? Thanks Nayn

• How ensure if java program uses UTF-8 encoding

  - by Nayn

  Hi, I recently discovered that relying on default encoding of JVM causes bugs. I should explicitly use specific encoding ex. UTF-8 while working with String, InputStynreams etc. I have a huge codebase to scan for ensuring this. Could somebody suggest me some simpler way to check this than searching the whole codebase. Thanks Nayn

• Java interface design

  - by Nayn

  Hi, I had an interface initially as below. public interface testMe { public Set<String> doSomething(); } public class A implements testMe { public Set<String> doSomething() { return // Set<String> } } I had similar classes implementing testMe. Now I have to add one more class which returns Set<Some Object> public class X implements testMe() { public Set<Some OBject> doSomething() { } } How could i add this mehtod in the interface without breaking existing classes? Thanks Nayn

• getTextContent from Node with whitespace character normalization

  - by Nayn

  Hi, I am working with XPATH, Java and want to extract some text out of one html page. The text is located under some div with some whitespace characters in between, like &nbsp; <br> etc. I want these to be converted into 'space' and 'newline' respectively while extracting. The method I am using to extract text is Element.getTextContent() which does not respect whitespace characters. Could somebody tell me if there is a way to extract text with whitespace normalization OR Extract whole html markup under the 'Node' so that i could replace it by myself. Thanks Nayn

  - by Nayn

  Hi, I have classes as below. public interface ITest <T> { public T MethodHere(); } public class test1 implements ITest<String> { String MethodHere(){ return "Bla"; } } public class test2 implements ITest<Integer> { Integer MethodHere(){ return Integer.valueOf(2); } } public class ITestFactory { public static ITest getInstance(int type) { if(type == 1) return new test1(); else if(type == 2) return new test2(); } } There is a warning in the factory class that ITest is used as raw type. What modification should I do to get rid of it? Thanks Nayn

• How safe is apache Commons-javaflow while using jasperreports

  - by Nayn

  Hi, I am using jasperreport and trying to pass an alternate report runner. • net.sf.jasperreports.engine.fill.JRThreadSubreportRunner: The initial thread-based implementation • net.sf.jasperreports.engine.fill.JRContinuationSubreportRunner: A Javaflow-based implementation I am using the second one (for the reason, it runs on tomcat server, and creating threads wouldn't be good while writing subreports). The second one depends on commons-javaflow which is a sandbox version. Not sure if I should use it, Could somebody suggest a better way. Thanks
