BIRT and Spring Integration

Hello Everyone,

I am integrating Birt with Spring and have got integration concept example from

http://www.springsource.org/Business...ndBIRT#frommvc

I have configured POJO based example and added all libraries

1. All library jars copied from birt-runtime-4_2_2\ReportEngine\lib
2. Using Tomcat 7
3.
spring-webmvc-portlet-3.2.0.RELEASE.jar
spring-webmvc-3.2.0.RELEASE.jar
spring-web-3.2.0.RELEASE.jar
spring-tx-3.2.0.RELEASE.jar
spring-test-3.2.0.RELEASE.jar
spring-struts-3.2.0.RELEASE.jar
spring-oxm-3.2.0.RELEASE.jar
spring-orm-3.2.0.RELEASE.jar
spring-jms-3.2.0.RELEASE.jar
spring-jdbc-3.2.0.RELEASE.jar
spring-instrument-tomcat-3.2.0.RELEASE.jar
spring-instrument-3.2.0.RELEASE.jar
spring-expression-3.2.0.RELEASE.jar
spring-core-3.2.0.RELEASE.jar
spring-context-support-3.2.0.RELEASE.jar
spring-context-3.2.0.RELEASE.jar
spring-beans-3.2.0.RELEASE.jar
spring-aspects-3.2.0.RELEASE.jar
spring-aop-3.2.0.RELEASE.jar
aopalliance-1.0.jar

after integration i am facing following exceptio

There are several spring integration posts in the devShare. Maybe one of the will help you out.

I think that last one might be the one you looked at already. Hopefully one of these helps you out. Let me know.

Thanks Williams for providing me others ways for birt integration with spring framework. 
 
I am working on the same integration ( <a class='bbc_url' href='http://www.springsource.org/Business...ndBIRT#frommvc'>http://www.springsource.org/Business...ndBIRT#frommvc</a> ) 
 
My previous problem fixed by adding resources in deployment Assembly in Eclipse and adding following new library to Java Build path 
 
org.springframework.web.servlet-3.2.0.RELEASE.jar and adding ... 
 
Now i am facing next problem in the Following Method 
 
public IReportEngine getObject(){ 
 
EngineConfig config = new EngineConfig(); 
System.out.println("Starting BIRT server "+ this.context.toString() ); 
 
//This line injects the Spring Context into the BIRT Context 
config.getAppContext().put("spring", this.context ); 
config.setLogConfig( null != this._resolvedDirectory ? this._resolvedDirectory.getAbsolutePath() : null , this.logLevel); 
try { 
Platform.startup( config ); 
} 
catch ( BirtException e ) { 
throw new RuntimeException ( "Could not start the Birt engine!", e) ; 
} 
 
IReportEngineFactory factory = (IReportEngineFactory) Platform.createFactoryObject( IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY ); 
IReportEngine be = factory.createReportEngine( config ); 
this.birtEngine = be ; 
 
System.out.println("BIRT Reporting Server initialised sucessfully"); 
 
return be ; 
} 
 
 
From above method factory object returns null which throws exception on folling lne of code 
IReportEngine be = factory.createReportEngine( config ); 
 
---- OTHER CLASS 
 
public class BirtWebConfiguration extends WebMvcConfigurerAdapter { 
 
 
@Override 
public void addViewControllers(ViewControllerRegistry registry) { 
registry.addViewController("/reports").setViewName("birtView"); 
 
} 
 
@Bean 
public BirtView birtView(){ 
BirtView bv = new BirtView(); 
//bv.setReportFormatRequestParameter("ReportFormat"); 
//bv.setReportNameRequestParameter("ReportName"); 
bv.setBirtEngine( this.engine().getObject() ); 
return bv; 
} 
 
 
@Bean public BeanNameViewResolver beanNameResolver(){ 
BeanNameViewResolver br = new BeanNameViewResolver() ; 
return br; 
} 
 
@Bean 
protected BirtEngineFactory engine(){ 
BirtEngineFactory factory = new BirtEngineFactory() ; 
//factory.setLogLevel( Level.FINEST); 
//factory.setLogDirectory ( new File ("c:/logs")); 
//factory.setLogDirectory( new FileSystemResource("/logs")); 
 
return factory ; 
} 
 
 
}

My aim is to make this exmple valueable for my project and will contribute the running example with detailed description to DevSource of BIRT . 
 
 
Can any body help me. i will be highly thankful.

Thanks Williams for providing me others ways for birt integration with spring framework. 
 
I am working on the same integration ( <a class='bbc_url' href='http://www.springsource.org/Business...ndBIRT#frommvc'>http://www.springsource.org/Business...ndBIRT#frommvc</a> ) 
 
My previous problem fixed by adding resources in deployment Assembly in Eclipse and adding following new library to Java Build path 
 
org.springframework.web.servlet-3.2.0.RELEASE.jar and adding ... 
 
Now i am facing next problem in the Following Method 
 
public IReportEngine getObject(){ 
 
EngineConfig config = new EngineConfig(); 
System.out.println("Starting BIRT server "+ this.context.toString() ); 
 
//This line injects the Spring Context into the BIRT Context 
config.getAppContext().put("spring", this.context ); 
config.setLogConfig( null != this._resolvedDirectory ? this._resolvedDirectory.getAbsolutePath() : null , this.logLevel); 
try { 
Platform.startup( config ); 
} 
catch ( BirtException e ) { 
throw new RuntimeException ( "Could not start the Birt engine!", e) ; 
} 
 
IReportEngineFactory factory = (IReportEngineFactory) Platform.createFactoryObject( IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY ); 
IReportEngine be = factory.createReportEngine( config ); 
this.birtEngine = be ; 
 
System.out.println("BIRT Reporting Server initialised sucessfully"); 
 
return be ; 
} 
 
 
From above method factory object returns null which throws exception on folling lne of code 
IReportEngine be = factory.createReportEngine( config ); 
 
public class BirtWebConfiguration extends WebMvcConfigurerAdapter { 
 
 
@Override 
public void addViewControllers(ViewControllerRegistry registry) { 
registry.addViewController("/reports").setViewName("birtView"); 
 
} 
 
@Bean 
public BirtView birtView(){ 
BirtView bv = new BirtView(); 
//bv.setReportFormatRequestParameter("ReportFormat"); 
//bv.setReportNameRequestParameter("ReportName"); 
bv.setBirtEngine( this.engine().getObject() ); 
return bv; 
} 
 
 
@Bean public BeanNameViewResolver beanNameResolver(){ 
BeanNameViewResolver br = new BeanNameViewResolver() ; 
return br; 
} 
 
@Bean 
protected BirtEngineFactory engine(){ 
BirtEngineFactory factory = new BirtEngineFactory() ; 
//factory.setLogLevel( Level.FINEST); 
//factory.setLogDirectory ( new File ("c:/logs")); 
//factory.setLogDirectory( new FileSystemResource("/logs")); 
 
return factory ; 
} 
 
 
}
