Re: JasperReports Serialization error with JRDataSource
That's how I use it not to have Serialisation problem :
JRResource resourcePDF = new
JRConcreteResource(reportFile, new PdfResourceHandler())
{
public JRDataSource getReportDataSource() {
//retrieve you data
//...
return new JRBeanCollectionDataSource(yourCollection);
}
public Map getReportParameters() {
Map params = new HashMap();
//set your parameters
params.put("base_path",
WebApplication.get().getServletContext().getRealPath(""));
return params;
}
};
Hope this help.
Gabriel.

JasperReports Serialization error with JRDataSource
Hey all,
I'm trying to build a ResourceLink to a JRResource but there's a
Serialization exception going on. Here is the snippet code:
final ServletContext context = ((WebApplication)
getApplication()).getServletContext();
final File reportFile = new
File(context.getRealPath("/reports/employeeReport.jasper"));
final Map parameters = new HashMap();
parameters.put("BaseDir", new File(context.getRealPath("/reports")));
JRResource pdfResource = new JRConcreteResource(reportFile, new
PdfResourceHandler()).setReportParameters(
parameters).setReportDataSource(new
JRBeanCollectionDataSource(service.listAll()));
add(new ResourceLink("linkToPdf", pdfResource));
The service variable is a @SpringBean.
Any idea anyone? (Eelco, specially... who wrote jasper integration on
wicketstuff)...
:-)

Yup - very true; I hadn't noticed that. All sorts of casts in the .equals that didn't validate that the inbound object was even of the same type. Fixed that and magically it went away.

Re: ClassLoader (Serialization?) error
I guess you use that panel somewhere on a page near a shared resource, maybe for an Image, have you tried debugging the rendering of that page? A side note, probably totally unrelated to your problem: having 'head' tags inside a wicket:panel will probably result in invalid html, you should consider using wicket:head instead (see: http://cwiki.apache.org/WICKET/wickets-xhtml-tags.html) cheers, Jonas On Mon, Mar 15, 2010 at 10:11 AM, Xavier López wrote: > I agree it's not a classloader issue, the classloader is being given a > cobbled class name, so it's not its fault it cannot load it. > > Is it possible that due to some serialization error the class name gets > messed with the html markup, so that the class name read in deserialization > ends messed up ? > > I don't see where can this be messing with comments, here is the markup file > (the only one with "fi usuari" in it) > > > > > > > > > > > key="userpanel.nomusuari.wai"/> wicket:id="nomUsuari"> > wicket:message="title:userpanel.editusuari.title"> key="userpanel.editusuari.text"/> > wicket:message="title:userpanel.homeadmin.title"> key="userpanel.homeadmin.text"/> > > > wicket:message="title:userpanel.fisessio.title" > wicket:id="linkFiSessio"> class="wai"> key="userpanel.fisessio.text.wai"/> > > > > > > > > > Thanks for all your responses ! > Xavier > > 2010/3/14 Jonas > >> As stated in my previous mail, I really doubt this is a classloader >> issue, since the class name is >> 'mypackage.MyClass-%20fi%20usuari%20--%3E%20%20%3C' >> which decodes to >> 'mypackage.MyClass- fi usuari --> <' >> which obviously isn't just a class name, but a class name >> plus some 'garbage', which will make any classloader choke. >> >> 2010/3/13 François Meillet : >> > sounds like a classloading effect. >> > >> > Have a look to the classloader hierarchy >> > >> > Here is a good doc: >> > >> http://download.oracle.com/docs/cd/E12840_01/wls/docs103/programming/classloading.html >> > >> > Especially this one : Resource Loading Order >> > >> http://download.oracle.com/docs/cd/E12840_01/wls/docs103/programming/classloading.html#wp1097288 >> > >> > François >> > >> > >> > Le 12 mars 2010 à 17:30, Igor Vaynberg a écrit : >> > >> >> ive seen this once before on the list. also with weblogic i think. >> >> search the list. >> >> >> >> -igor >> >> >> >> On Fri, Mar 12, 2010 at 3:16 AM, Xavier López >> wrote: >> >>> Hi, >> >>> >> >>> From time to time I see the following error in my deployed >> application's >> >>> log.

Re: ClassLoader (Serialization?) error
I agree it's not a classloader issue, the classloader is being given a cobbled class name, so it's not its fault it cannot load it. Is it possible that due to some serialization error the class name gets messed with the html markup, so that the class name read in deserialization ends messed up ? I don't see where can this be messing with comments, here is the markup file (the only one with "fi usuari" in it) Thanks for all your responses !

Re: ClassLoader (Serialization?) error
Looks like a resource called 'mypackage.MyClass fi usuari --> behind. So, I guess you don't have a ClassLoader issue here, nor a Serialization issue. cheers, Jonas On Fri, Mar 12, 2010 at 12:16 PM, Xavier López wrote: > Hi, > > From time to time I see the following error in my deployed application's > log.

ClassLoader (Serialization?) error
Hi, >From time to time I see the following error in my deployed application's log. The application is running clustered on Weblogic 9.2 MP3. It seems to be messing up with the classloading of class mypackage.MyClass (this error comes up in many different classes).

Re: Serialization Error
comparator does not extend serializable.
make an inner class that extends serializable.

It seems to be complaining about this:

Comparator() {
@Override
public int compare(Monitor o1, Monitor o2) {

}
});
Shouldn't a comparator for a serializable also be serializable?
If this is in face not serializable, how do I work around this?
