java.lang.ClassNotFoundException: com.sun.jersey.api.client.GenericType

I use GenericType on project web java(serverlet). When I run project, it has error. Although, I imported lib: jersey-core-1.19.1.jar.

With commons-collections.jar should be enough, check that you have the jar on WEB-INF/lib of your web application

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()
CloudBalance solvedCloudBalance = (CloudBalance) solver.getBestSolution()
render(view: "create", model: [cloudBalanceDomainInstance: cloudBalanceDomainInstance])
flash.message = message(code: 'default.created.message', args: [message(code: 'cloudBalanceDomain.label', default: 'CloudBalanceDomain'), cloudBalanceDomainInstance.id])
render "${getToDisplayString(solvedCloudBalance)}"
//redirect(action: "show", showStr: getToDisplayString(solvedCloudBalance))
}
On running, it returns following exception:
Executing action [save] of controller [optaplannergrails.CloudBalanceDomainController] caused exception: Runtime error executing action

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"))

There's a bug for this against the Spring Security Core grails plugin: https://jira.grails.org/browse/GPSPRINGSECURITYCORE-70

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:
Mar 17, 2013 2:27:14 PM org.apache.catalina.core.StandardWrapperValve invoke

Your cos and sin methods need to be static.
