NullPointer at referenced object with scripted Dataset

Simon Hanika

Hi,
 
I have a problem with scripted Datasets.
 
I created a report with a scripted dataset which should enter a method of a class and at the result I am getting a filled POJO out. This is all going well as long as I just work with local variables.
 
My application uses Spring and Dependency injection and The class I am using is a one of the Spring beans.
 
All attributes and services which should be filled and initialized are empty or null. 
I think I have to give BIRT something like a proxy or classpath variable but I am not sure how this could work?
I also read something about giving the IRunTask Objet a scrptable Object (maybe with addScriptableJavaObject()-Method (which is deprecated!)) 
 
Can anybody give me a hint what is missing?
 
Thanks 
Simon

Hi,
 
I found a solution with this article:
 
<a data-ipb='nomediaparse' href='http://forum.spring.io/forum/spring-projects/container/59160-loading-applicationcontext-from'>http://forum.spring.io/forum/spring-projects/container/59160-loading-applicationcontext-from</a>
 
You can create a class such as bellow:
<div style="margin:0px;font-size:13px;font-family:Helvetica, Arial, Verdana, sans-serif;color:rgb(37,44,47);">
<div style="margin:10px 0px 0px;font-family:inherit;">Code:</div>
public class SpringApplicationContextHolder implements applicationContextAware { 
 
 static ApplicationContext context; 
 public void setApplicationContext( 
 ApplicationContext applicationContext) { 
 context = applicationContext; 
 } 
 public static void setAppContext( 
 ApplicationContext applicationContext) { 
 context = applicationContext; 
 } 
 public static ApplicationContext getApplicationContext() { 
 return context; 
 } 
 public static Object getBean(String name) { 
 return getApplicationContext().getBean(name); 
 } 
}</div>
and create a bean such as bellow:
<div style="margin:0px;font-size:13px;font-family:Helvetica, Arial, Verdana, sans-serif;color:rgb(37,44,47);">
<div style="margin:10px 0px 0px;font-family:inherit;">Code:</div>
<bean id="springUtilInitializer" 
class="ir.asta.wise.core.util.SpringApplicationContextHolder" lazy-init="false" /></div>
and simply use static method in pojo: 

<div style="margin:0px;font-size:13px;font-family:Helvetica, Arial, Verdana, sans-serif;color:rgb(37,44,47);">
<div style="margin:10px 0px 0px;font-family:inherit;">Code:</div>
SpringApplicationContextHolder.getBean("myBean")
 
this works for me but maybe there is a better solution anybody knows?
