Does anybody know what to do?
OS: Ubuntu 12.04 LTS
MYSQL V 5.5.40
Installed using Ganib WAR File

The database was not writable from outside localhost. I allowed connections from outside and it worked perfectly for me.

How to add a new page in Spring Roo and invoke action after clicking on the button?

I would like to know how to add a new page in Spring Roo and invoke action after clicking on the button?
Currently I am able to add a user to the database after clicking the save button. All the files in Spring Roo were generated automatically. I have just followed the instructions for Spring Roo. I would like to continue developing the app and create a new page that is generated after clicking the save button. On the page will be basically displayed the information like "New user was added successfully". I think I will first check if the user is in the specific table and if is I will return false it will means that the adding user to the database was not successful otherwise I will display "New user was added successfully". I followed the rules from here Adding a custom page in spring roo but it is about adding a custom page to Spring Roo and there is missing that part of how to create that page first. When I follow the rules from the link I get this error:

I use to use Eclipse and Spring Roo is so new for me. I tried tutorial but this what I am doing it not explained well. I will be deeply grateful. If you show me the way. Thank you. If you need to post some other info please let me know.

I think problem because messageSource in Spring . So you should find the file messages_en.properties or messages.properties or some file like *.properties in your project. Path of .properties file can change in dispathcher-servlet.xml ( so check src/main/java/resource )
<context:property-placeholder location="classpath*:META-INF/spring/*.properties"/>
or the bean with id="messageSource" similarly
<bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
<property name="basenames">
<list>
<value>/WEB-INF/resources/messages</value>
</list>
</property>
<property name="defaultEncoding" value="UTF-8" />
</bean>
After found the messages.properties (or something.properties base on config) , You should add a property to it
menu_category__label=example label
You could read more about Spring MVC Internationalization at Spring locale
think it could help.

The solver configuration does not exist error in grails optaplanner

I am trying to run the cloud balancing example as in optaplanner site here. I have placed the cloudBalancingSolverConfig.xml file in web-app/xmls directory. Here is my code of the save action of CloudBalanceDomainController:
def save() {
def serveletContext = ServletContextHolder.servletContext
def storagePath = serveletContext.getRealPath( "/" )
String temp=storagePath+"xmls"+File.separator+"cloudBalancingSolverConfig.xml"
File f=new File(temp)
if(f.exists())
println "file exists!"
SolverFactory solverFactory=new XmlSolverFactory(temp)
Solver solver=solverFactory.buildSolver()
CloudBalance unsolvedCloudBalance=new CloudBalancingGenerator().createCloudBalance(params.computers,params.processes)
solver.setPlanningProblem(unsolvedCloudBalance);
solver.solve()

It says that java.lang.IllegalArgumentException: The solver configuration (C:\Users\....\IdeaProjects\OptaPlannerGrails\web-app\xmls\cloudBalancingSolverConfig.xml) does not exist.
However, surprising thing is that f.exists() returns true, hence the file is being found. So what may be causing this error?
EDIT:
f.canRead() and f.canWrite() also returns true.Hence the file has both read and write permissions. Although it does not need to write to the file here.

It's looking for the solver configuration in the classpath with getClass().getResource("..."). Files or URL's are not supported that way (but you can mimic this by building your own KieBase base upon a file).
So if your file is in C:\Users\....\IdeaProjects\OptaPlannerGrails\src\main\resources\org\foo\bar\solverConfig.xml in a maven project, you 'd get it with /org/foo/bar/solverConfig.xml because src/main/resources is part of the java classpath in maven. If web-app\xmls\ is part of the classpath (which it probably isn't because it's part of the war resources probably) just cloudBalancingSolverConfig.xml would work.
Anyway, you probably want to make sure your xml ends up in yourWebApp.war!/WEB-INF/classes/org/foo/bar/solverConfig.xml and load it with /org/foo/bar/solverConfig.xml

If other answers do not help (like in my case when packaging solverConfig.xml into a Spring Boot application) then this small change might help you out:
SolverFactory.<PlanningSolution<BendableScore>>createFromXmlInputStream(
getClass().getClassLoader().getResourceAsStream("org/foo/bar/solverConfig.xml"))

Very simple custom taglib function not working

I'm banging my head over why my custom taglib function isn't working. The example is using Math.cos and Math.sin.
Here's the class:
package foo.tags;
public class Math {
public java.lang.Double cos(java.lang.Double value) {
return java.lang.Math.cos(value);
}
public java.lang.Double sin(java.lang.Double value) {
return java.lang.Math.sin(value);
}
}
Here's the .tld file:
<taglib xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee/web-jsptaglibrary_2_0.xsd"
version="2.0">
<tlib-version>2.0</tlib-version>
<uri>/WEB-INF/tags/math.tld</uri>
<function>
<name>cos</name>
<function-class>foo.tags.Math</function-class>
<function-signature>java.lang.Double cos(java.lang.Double)</function-signature>
</function>
<function>
<name>sin</name>
<function-class>foo.tags.Math</function-class>
<function-signature>java.lang.Double sin(java.lang.Double)</function-signature>
</function>
</taglib>
Important snippets of the calling code:
<%# taglib prefix="math" uri="/WEB-INF/tags/math.tld" %>
<span>${math:sin(180)}</span>
I am getting a null pointer exception on the line with math:sin(180). Does anyone see what I'm doing wrong? Let me know if more info is needed but the exception itself isn't very informative.
Edit
Here's the stacktrace:
