NoClassDefFoundError for JRStyledTextParser

[pensashure]

Hi,

 

I recently installed JasperReports 3.7.2 on WebLogic 11g. When trying to generate a report I'm getting:

 

java.lang.NoClassDefFoundError: net/sf/jasperreports/engine/util/JRStyledTextParser at net.sf.jasperreports.engine.fill.JRBaseFiller.(JRBaseFiller.java:181) at net.sf.jasperreports.engine.fill.JRVerticalFiller.(JRVerticalFiller.java:76) at net.sf.jasperreports.engine.fill.JRVerticalFiller.(JRVerticalFiller.java:86) at net.sf.jasperreports.engine.fill.JRVerticalFiller.(JRVerticalFiller.java:56) at net.sf.jasperreports.engine.fill.JRFiller.createFiller(JRFiller.java:142) at net.sf.jasperreports.engine.fill.JRFiller.fillReport(JRFiller.java:78) at net.sf.jasperreports.engine.JasperFillManager.fillReport(JasperFillManager.java:624) at org.springframework.web.servlet.view.jasperreports.AbstractJasperReportsView.fillReport(AbstractJasperReportsView.java:676) at org.springframework.web.servlet.view.jasperreports.AbstractJasperReportsView.renderMergedOutputModel(AbstractJasperReportsView.java:570) at org.springframework.web.servlet.view.AbstractView.render(AbstractView.java:257) at org.springframework.web.servlet.DispatcherServlet.render(DispatcherServlet.java:1183) at org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:902) at org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:807) at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:571) at org.springframework.web.servlet.FrameworkServlet.doPost(FrameworkServlet.java:512)

 

May you give me a hint or tell me what is the error?

 

Thanks in advance.

Finally, I've got it working. I detected the root Exception, which was thrown before NoClassDefFoundError:net/sf/jasperreports/engine/util/JRStyledTextParser :

java.lang.NoClassDefFoundError: sun/awt/X11GraphicsEnvironment

The Sun AWT classes on Unix and Linux have a dependence on the X Window System. When you use these classes, they expect to load X client libraries and be able to talk to an X display server. This makes sense if your client has a GUI; unfortunately, it's required even if your client uses AWT but does not have a GUI (which is my case, generating a report from a web application)

The way to bypass this, is setting a system property java.awt.headless=true on system startup.
