thank you for the reply, i'll change the path and see how it goes.
thanks

Assuming that it is Tomcat that is blowing up with this error, open the Tomcat server (right-click on Tomcat in Server view and select open) then click Open Launch Configuration. On the Arguments tab, add "-XX:MaxPermSize=256M" to the VM Arguments.

If it is Eclipse that is blowing up, edit the value after the "--launcher.XXMaxPermSize" line in eclipse.ini.

Hi, this works perfectly!!
Thank you very much.
Now iém getting this

Caused by: java.io.FileNotFoundException: /Users/DennisFaggiani/Documents/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/FinanceiroWeb/relatorios/contas.jasper ... 72 more

I created the file "contas.jasper" in this path "/Users/DennisFaggiani/Documents/workspace/FinanceiroWeb/financeiro/relatorios/contas.jasper" But it seems that it looking for in the wrong place, this is my class where i generate the report

Any ideas?
Thank you very much.

Hi guys, i'm getting an exception and i don't know how to fix it.
This started after i insert the ireport into my project.
I've already tryed to increase the JVM memory from the eclipse.ini, and tryed to pass arguments to Tomcat, but notthing seems to work, my project is over 30mb, i don't know if that's the problem, this is the exception i'm getting

SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from ServletContext resource [/WEB-INF/applicationContext.xml]; nested exception is java.lang.OutOfMemoryError: PermGen space

does anyone can help me? i'm kind of desperate, it's been three days trying to fix it, and i'm not getting any success.
Thank you.

Hi guys, i'm having some trouble to create a piechart from a list

primefaces version 3.0.M3
tomcat version 7.0

this is the error i'm getting

Sep 20, 2011 6:33:59 PM com.sun.faces.application.view.FaceletViewHandlingStrategy handleRenderException SEVERE: Error Rendering View[/restrito/acao.xhtml] java.lang.ClassCastException: java.util.ArrayList cannot be cast to org.primefaces.model.chart.PieChartModel

this is where i call the list

<ui:composition> <h:panelGrid width="100%"> <h:form id="graficosCarteira"> <h:panelGrid columns="2" width="100%"> <p:panel header="Composição carteira em % de quantidade" toggleable="true" toggleSpeed="500"> <p:pieChart value="#{acaoBean.lista}" var="acaoVirtual" categoryField="#{acaoVirtual.acao.sigla}" dataField="#{acaoVirtual.acao.quantidade}" width="265px" height="125px" style="estiloGrafico" /> </p:panel> <p:panel header="Composição carteira em % de valor" toggleable="true" toggleSpeed="500" style="margin-left:+10px;"> <p:pieChart value="#{acaoBean.lista}" var="acaoVirtual" categoryField="#{acaoVirtual.acao.sigla}" dataField="#{acaoVirtual.total}" width="265px" height="125px" style="estiloGrafico" /> </p:panel> </h:panelGrid> </h:form> </h:panelGrid> </ui:composition>

and this is the list

public List<AcaoVirtual> getLista() { FacesContext context = FacesContext.getCurrentInstance(); ContextoBean contextoBean = ContextoUtil.getContextoBean(); AcaoRN acaoRN = new AcaoRN(); try { if (this.lista == null) { this.lista = acaoRN.listarAcaoVirtual(contextoBean.getUsuarioLogado()); } } catch (RNException e) { context.addMessage(null, new FacesMessage(e.getMessage())); } return this.lista; }

Can anyone tell me what i'm doing wrong?

the AcaoVirtual is here:

public class AcaoVirtual { private Acao acao = new Acao(); private float ultimoPreco; private float total; public Acao getAcao() { return acao; } public void setAcao(Acao acao) { this.acao = acao; } public float getUltimoPreco() { return ultimoPreco; } public void setUltimoPreco(float ultimoPreco) { this.ultimoPreco = ultimoPreco; } public float getTotal() { return total; } public void setTotal(float total) { this.total = total; } }

Thank you very much.
