createFactoryObject returns null after upgrade of BIRT [message #665718] Fri, 15 April 2011 15:20 Go to next message

Hi,
After an upgrade of BIRT from version 2.2.1.1 to 2.6.2 I have a similar problem as many older bugs I've found in here. I cant find an answer that fixes my problem, though.

My problem is that I get a NullPointerException due to that the method createFactoryObject returns null.
I have verified that the engine path is correct, and that all permissions are correct. All the jar-files from the lib-library and no other are placed correctly.

Now I'm stuck on what to look at or try to make this work, and I appreciate any help on the topic!

The code that generates the nullpointer:
IReportEngineFactory factory = (IReportEngineFactory) Platform.createFactoryObject(IReportEngineFactory.EXTENSION_ REPORT_ENGINE_FACTORY);
birtEngine = factory.createReportEngine(config);


The log:
java.lang.NullPointerException

In the runtime directory look for the configuration folder. clear
everything but the config.ini. Try to start it again and see if any
files are generated in this directory.

We actually tried emptying everything but the config.ini from the configuration folder directly after I posted this question. But this did not work either for us.
We did however found a solution. We removed the whole ReportEngine folder from the server and downloaded a new birt-runtime-2_6_2. Then we copied the ReportEngine folder from the new download over to the server and like magic, the problem then vanished Smile

Thanks a lot though for the quick answer!

Hi

I am new to BIRT. I am using BIRT 4.2

I am facing similar problem. I have a maven project. My BIRT dependency looks like this:

<dependency>
	<groupId>org.eclipse.birt.runtime</groupId>
	<artifactId>org.eclipse.birt.runtime</artifactId>
	<version>4.2.0</version>
</dependency>


And when I run my application through eclipse, it works fine.

But when I creat a jar with dependencies using maven-assembly-plugin and try to run it. The createFactoryObject returns null.

Any help ...?

Thanks

Thanks for the response Jason.

Here is the pom. I had to strip the urls because: "You can only use links to eclipse.org sites while you have fewer than 25 messages."

Can you look at the jars that get downloaded? Do they match the jars in
the runtime download of BIRT 4.2. Specifically the ones in the
reportengine/lib directory of the runtime download?

Thanks for the reply Jason.

Sorry to be this late with reply but I got around the problem. I am posting my solution here so that it might be helpful for someone else.

Yes, I verified the downloaded jars.

What I did to resolve this, however, was to copy the all the dependencies into a folder:

<plugin>
<artifactId>maven-dependency-plugin</artifactId>
<version>${dependency-plugin.version}</version>
<executions>
<execution>
<phase>install</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/lib</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
<plugin>


and then added them to classpath.

I was trying to create a single jar so that there may be no hassle in deployment/installation. But it seems to be a better solution to me since if I have a change in my code, I would need to replace my jar only.

I am coming to this discussion a couple of years too late, but I am wondering if anyone has solved Omer's issue without the workaround?

While I appreciate the workaround, it still doesn't give me the ideal solution I would like of having a single deployable jar with my application in it.

I am using org.eclipse.birt.runtime version 4.4.1 and Eclipse Luna and am having the same exact issue.
The code runs fine in eclipse, but I get an NPE on createFactoryObject when I create a jar with dependencies using the maven-assembly-plugin.

BTW, my pom is essentially the same as Omer's except I have some other dependencies for other aspects of my application.

Finally, I am sorry for re-animating an apparent zombie thread, but I could not find anywhere else but here that this specific problem was mentioned.
