NoClassDefFoundError on OC4J

2005-05-10 01:53

Hi,

 

I've been developing reports wirh jasperreports and ireports and using them on tomcat smothly.

 

The problem has come when we tried to use them on a OC4J web app. We load the report, (with JRLoader.loadObject) but when we invoke the filler (JasperFillManager.fillReport) the server returns a noClassDefFound error.

 

We're running OC4J ver. 9.i, with jasperReports 0.6.6 and JRE 1.4.2. The error shown is this:

 

 

java.lang.NoClassDefFoundError: net.sf.jasperreports.engine.fill.JRVerticalFiller

net.sf.jasperreports.engine.JasperPrint

net.sf.jasperreports.engine.fill.JRFiller.fillReport(net.sf.jasperreports.engine.JasperReport,

java.util.Map, java.sql.Connection)

net.sf.jasperreports.engine.JasperPrint

net.sf.jasperreports.engine.JasperFillManager.fillReport(net.sf.jasperreports.engine.JasperReport,

java.util.Map, java.sql.Connection)

java.lang.String com.treballrat.cmd.LlistarFitxesCmd.execute(javax.servlet.http.HttpServletRequest,

java.util.HashMap)

void rxc.FlowControl.service(javax.servlet.http.HttpServletRequest,

javax.servlet.http.HttpServletResponse)

void javax.servlet.http.HttpServlet.service(javax.servlet.ServletRequest,

javax.servlet.ServletResponse)

void com.evermind[Oracle9iAS (9.0.2.0.0) Containers for J2EE].server.http.ServletRequestDispatcher.invoke(javax.servlet.ServletRequest,

javax.servlet.ServletResponse)

void com.evermind[Oracle9iAS (9.0.2.0.0) Containers for J2EE].server.http.ServletRequestDispatcher.forwardInternal(javax.servlet.ServletRequest,

javax.servlet.http.HttpServletResponse)

boolean com.evermind[Oracle9iAS (9.0.2.0.0) Containers for J2EE].server.http.HttpRequestHandler.processRequest(com.evermind[Oracle9iAS

(9.0.2.0.0) Containers for J2EE].server.ApplicationServerThread,

com.evermind[Oracle9iAS (9.0.2.0.0) Containers for J2EE].server.http.EvermindHttpServletRequest, com.evermind[Oracle9iAS

(9.0.2.0.0) Containers for J2EE].server.http.EvermindHttpServletResponse, java.io.InputStream, java.io.OutputStream, boolean)

void com.evermind[Oracle9iAS (9.0.2.0.0) Containers for

J2EE].server.http.HttpRequestHandler.run(java.lang.Thread)

void com.evermind[Oracle9iAS (9.0.2.0.0) Containers for

J2EE].util.ThreadPoolThread.run()

 

Any help would be appreciated.

Thanks,

Tomas
