Hi,

I have struts.xml (Struts 2) file as shown below

<struts> <constant name="struts.enable.DynamicMethodInvocation" value="false"/> <constant name="struts.devMode" value="true" /> <package name="reports" namespace="/reports" extends="json-default, hibernate-default"> <action name="ShowReportList" class="com.ql2.reports.actions.ShowReportList" method="initializeReportList"> <result>/pages/ReportList.jsp</result> </action> <action name="ShowReportInputParams" class="com.ql2.reports.actions.ShowReportInputParams" method="initializeReportObjects"> <result>/pages/ReportInputParams.jsp</result> </action> <action name="SaveAndViewReport" class="com.ql2.reports.actions.SaveAndViewReport" method="saveAndViewReport"> <result>/pages/ReportTableau.jsp</result> </action> <action name="GetContextFilterData" method="extractData" class="com.ql2.reports.actions.GetContextFilterData"> <result type="json" /> </action> </package> </struts>

But in this xml the line extends="json-default, hibernate-default" is coming in red with error "Cannot resolve package json-default, hibernate-default". I have put the plugin jars for both in the lib folder, these jars are struts2-fullhibernatecore-plugin-2.2.2-GA.jar, struts2-json-plugin-2.1.8.jar and i have associated there plugin xmls in Struts2 facets in project settings. Also, if I use either of them in the extends attribute this error does not come. I am using Intellij Idea as the IDE for development.

Are there any other settings that needs to be done other than those described above or what can be solution to this problem?

Thanks Paul.

Paul Clapham wrote:Without knowing anything else about the application, it's impossible to say. That code is perfectly good as it is, but we have no idea whether you have seven other instances of very similar code elsewhere in the application. If you do, then you ought to make a separate class to refactor those seven instances.

Hi Paul,

This code is getting used nowhere else in the application, actually this is a separate service that on the completion of some task, sends an email to the recipients. Should I extract it to a separate class keeping in mind that in future there can be requirement of such kind but currently i don't see any other place where it is required. So, please suggest what should be done in this case? Which is the better practice in terms of a good design perspective?

// Create a send email task. Callable emailTask = new Callable() { @Override public Object call() throws Exception { //Send E-Mail. return new EMail(mailProps) { @Override protected String getSubject() { return MessageFormat .format( emailNodes[0], String.valueOf(runId)); } @Override protected String getBody() { return MessageFormat .format(emailNodes[1], String.valueOf(runId), zipArchivePath.getPath()); } @Override protected String[] getRecipients() { return toEmailAddresses.split(","); } @Override protected String getFromAddress() { return fromEmailAddress; } @Override protected String[] getAttachments() { return new String[0]; } }.sendMessage(); } };

In the above code should the Callable task be declared as above or a separate class? If it should be used as an external class then please tell the reason for the same.

Thanks for your reply, i will try that.

I have an application in which i am creating 3 services and i have the following log4j.properties file for the application.
log4j.rootLogger=DEBUG, Stdout log4j.logger.com.ql2.etl=DEBUG, EtlFileAppender log4j.logger.com.ql2.runcompletion=DEBUG, RCFileAppender log4j.logger.com.ql2.runarchive=DEBUG, RAFileAppender ############ Console Appender ################################################# log4j.appender.Stdout=org.apache.log4j.ConsoleAppender log4j.appender.Stdout.layout=org.apache.log4j.PatternLayout log4j.appender.Stdout.layout.ConversionPattern=%5p %d{dd MMM yyyy HH:mm:ss,SSS} [%F:%L] (%c) - %m%n ############ End Of Console Appender ########################################### ########### ETL Service Appender ############################################### log4j.appender.EtlFileAppender=org.apache.log4j.RollingFileAppender log4j.appender.EtlFileAppender.File=etl_service/etl.log log4j.appender.EtlFileAppender.MaxFileSize=100KB log4j.appender.EtlFileAppender.MaxBackupIndex=1 log4j.appender.EtlFileAppender.layout=org.apache.log4j.PatternLayout log4j.appender.EtlFileAppender.layout.ConversionPattern=%p %d{dd MMM yyyy HH:mm:ss,SSS} [%F:%L] %c - %m%n ########## End Of ETL Service Appender ######################################### ########### Run Completion Service Appender #################################### log4j.appender.RCFileAppender=org.apache.log4j.RollingFileAppender log4j.appender.RCFileAppender.File=runcompletion_service/runcompletion.log log4j.appender.RCFileAppender.MaxFileSize=100KB log4j.appender.RCFileAppender.MaxBackupIndex=1 log4j.appender.RCFileAppender.layout=org.apache.log4j.PatternLayout log4j.appender.RCFileAppender.layout.ConversionPattern=%p %d{dd MMM yyyy HH:mm:ss,SSS} [%F:%L] %c - %m%n ########## End Of Run Completion Service Appender ############################## ########### Run Archive Service Appender ####################################### log4j.appender.RAFileAppender=org.apache.log4j.RollingFileAppender log4j.appender.RAFileAppender.File=runarchive_service/runarchive.log log4j.appender.RAFileAppender.MaxFileSize=100KB log4j.appender.RAFileAppender.MaxBackupIndex=1 log4j.appender.RAFileAppender.layout=org.apache.log4j.PatternLayout log4j.appender.RAFileAppender.layout.ConversionPattern=%p %d{dd MMM yyyy HH:mm:ss,SSS} [%F:%L] %c - %m%n ########## End Of Run Archive Service Appender ##############################

Now, whenever i run these services from their main class all the service log files get generated but i want only the log file for that service should get generated. Can I achieve this thing in the same log4j.properties file or do i need to have separate properties file for each service? Please suggest.

Thanks Campbell and Rob for your valuable replies.

Thanks Walter for your reply, Is there anyway that Wrapper types are more preferable over primitive types, and is this a design practice to always use wrapper types in POJO.

When we are making a class that has an id field which is Bigint in database which type should be used? Should a long primitive type be used or Long wrapper type? Please clarify.

Which Software development methodology is better out of Spiral and Agile and why?

Hi Sean,

As asked by you, I have listed down the agile development principles, so please relate these principles to Agile hiring.

Agile Development Principles

Our highest priority is to satisfy the customer
through early and continuous delivery
of valuable software.

Welcome changing requirements, even late in
development. Agile processes harness change for
the customer's competitive advantage.

Deliver working software frequently, from a
couple of weeks to a couple of months, with a
preference to the shorter timescale.

Business people and developers must work
together daily throughout the project.

Build projects around motivated individuals.
Give them the environment and support they need,
and trust them to get the job done.

The most efficient and effective method of
conveying information to and within a development
team is face-to-face conversation.

Working software is the primary measure of progress.

Agile processes promote sustainable development.
The sponsors, developers, and users should be able
to maintain a constant pace indefinitely.

Continuous attention to technical excellence
and good design enhances agility.

Simplicity--the art of maximizing the amount
of work not done--is essential.

The best architectures, requirements, and designs
emerge from self-organizing teams.

At regular intervals, the team reflects on how
to become more effective, then tunes and adjusts
its behavior accordingly.

Thanks in anticipation.

Thanks Sean for explaining how the concept of agile can be applied to hiring as well, you explained it precisely. I am looking forward for this one so that it can benefit my hiring force as well as improve the hiring process overall. Good Work

How can I improve the hiring process in my organization by using Agile Hiring?

Heard about Agile development but "Agile Hiring" seems unheard. What are the ways in which this agile hiring is different from normal hiring? I want to improve the hiring process in my organization so what is that I can expect from Agile Hiring?

Hi,

I am using the below code to switch from http to https on the login page.

<security-constraint> <web-resource-collection> <web-resource-name>CC Secure</web-resource-name> <url-pattern>/login.jsp</url-pattern> </web-resource-collection> <user-data-constraint> <transport-guarantee>CONFIDENTIAL</transport-guarantee> </user-data-constraint> </security-constraint>

How to switch back from https to http?

A solution I read on one of the posts is to provide the next url as absolute by prefixing the url with http:// and hence all the other urls will be relative to this http. But in this case I don't know how to get the port number for http as I am currently on https.

Please help me on the same.
