Before using XDocReport in Web App, I suggest you to use it in simple Java main 
to discover if it's a problem with report.

Thanks for your reply,

I tried using XDocReport with Java Main and it is working ok, i don´t see any 
problem with report. In fact, if in request i send the parameter processState 
with value "preprocessed" an Odt file is generated ok, but with no values in 
velocity fields

Thanks

What info do you need? I attach  the dispather and de jsp code is:

<form name="XdocReportForm"  action="/Contratacion/reportDispatcher"  
method="post">
                <input type="hidden" name="reportId" value="Pepe.odt"/>
                <input type="hidden" name="processState" value="generated"/>
                <input type="hidden" name="dispatch" value="view"/>

            </form>

The dispatcher is defined in web.xml as follows:
<servlet>
    <servlet-name>MyDispatcherReportServlet</servlet-name>
    <servlet-class>fr.opensagres.xdocreport.document.web.dispatcher.ProcessDispatcherXDocReportServlet</servlet-class>
    <init-param>
        <param-name>dispatchers</param-name>
        <param-value>es.di.dipcast.contratacion.actions.expedientes.pliegos.MyDispatcher</param-value>
    </init-param>
    <init-param>
        <param-name>cacheOriginalDocument</param-name>
        <param-value>true</param-value>
    </init-param>
  </servlet>
  <servlet-mapping>
    <servlet-name>MyDispatcherReportServlet</servlet-name>
    <url-pattern>/reportDispatcher/*</url-pattern>
  </servlet-mapping>

and i attach de servlet defined.

Thanks

I don't understand how you can have NPE. To understand it, I need to debug it, 
in other words I need your full webapp. Please create and attach a simple 
webapp which causes your problem.

GoogleCodeExporter commented 9 years ago 
sorry but it is imposible to attach you my full app, and if i create another 
simple one it won't be equal than original. My impression is the problem should 
be for incompatibility of JARS or missing library or wrong version because i 
tried to do with servle instead of dispatcher ant i got the same error.

No ideas then?

Thanks

I have no idea how you could have this problem. Without debugging application, 
I cannot help you more.

Ok so i tried to change using freemarker instead of velocity and im getting 
this error, maybe you can help with that??

java.lang.AbstractMethodError: 
fr.opensagres.xdocreport.template.freemarker.FreemarkerDocumentFormatter.getStar
tIfDirective(Ljava/lang/String;)Ljava/lang/String;
fr.opensagres.xdocreport.core.XDocReportException:

        at fr.opensagres.xdocreport.document.preprocessor.AbstractXDocPreprocessor.preprocess(AbstractXDocPreprocessor.java:118)

I have no experience working with freemarker. The template can be a ODT file?

judass8,

I have not a lot of time, so :

1) please attach simple sources which causes problem (I suggest you that you 
create a little WebApp from scratch to discover your problem).
2) please take time to learn Freemarker if you want to use Freemarker.

Hi,

@judass8

It looks like you are using a recent version of 

fr.opensagres.xdocreport.template.freemarker.jar

with an older version of 

fr.opensagres.xdocreport.template.jar

Please make sure all your xdocreport modules versions are aligned or use the 
xdocreport "All in One" jar :

https://code.google.com/p/xdocreport/downloads/list

Regards.

@judass8 we cannot try and guess your context, so if you want help, please 
attach a simple webapp which causes your problem, otherwise we will close this 
issue.

Due to schedule problems i can not waste time on making a new app sorry. I will 
not use XdocReport this time, so you can close this issue.

Thanks for your time
