Erro no Ireport

alguem ja viu esse?? Vi na net que é um problema de bibliotecas… mas adicionei todas as bibliotecas de um outro projeto que o mesmo arquivo do ireport roda (la funciona) e no meu projeto da este erro

Qual fonte vc usou nas letras do relatorio?

Se vc usa GWT pode ser esse o problema!

Estou usando o netbeans 7 para gerar um relatorio, mas esta acontecendo o seguinte erro no iReport na hora que eu clico em preview:

Compiling to file... C:\Users\New Dev\Documents\Sistema de Soma\Nova pasta\relatorio2.jasper Error compiling the report java source! net.sf.jasperreports.engine.JRRuntimeException: Not able to load JDT classes at net.sf.jasperreports.engine.design.JRJdtCompiler.<init>(JRJdtCompiler.java:125) at com.jaspersoft.ireport.designer.compiler.ExtendedJRJdtCompiler.<init>(ExtendedJRJdtCompiler.java:50) at com.jaspersoft.ireport.designer.compiler.IReportCompiler.run(IReportCompiler.java:501) at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:1424) at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:1968) Caused by: java.lang.NoSuchMethodException: org.eclipse.jdt.internal.compiler.env.NameEnvironmentAnswer.<init>(org.eclipse.jdt.internal.compiler.env.IBinaryType) at java.lang.Class.getConstructor0(Class.java:2706) at java.lang.Class.getConstructor(Class.java:1657) at net.sf.jasperreports.engine.design.JRJdtCompiler.<init>(JRJdtCompiler.java:119) ... 4 more Compilation running time: 10

o meu erro nao resolvi…desisntalei e reinstalei os 2 e nada… eu uso fonts comuns, arial, currier,sanseriff… nada demais… engraçado que o mesmo arquivo jxrml em outro projeto funciona…e as bibliotecas sao as mesmas

foi oque eu falei no inicio. vc nao ta usando GWT?

nao…
