How to publish Java event handlers in JAR files

Hello,

I have created a Java event handler (overloading fetch) to access SQL data from a scripted data set. I have succeeded in doing this in Eclipse and I am able to run the report by clicking the ?Preview? tab in Eclipse. The BIRT report is in one Eclipse project and the Java code is in another Eclipse project.

Unfortunately I have not been able to figure out how to run this report from iServer Express. I have used instructions from the book ?Integrating and Extending BIRT? and well as documents from this website. (?Overview - Publish BIRT Resources to Iserver Express? and ?Overview ? Publish Reoprts to iServer Express?). I have published the report and the JAR file containing the event handler class to iServer Express in multiple locations with multiple methods, but I always get the error message ?Unhandled exception when executing report?.

Is there a document that gives a specific example of loading a Java resource JAR file (not Java script)? I would greatly appreciate any guidance you could provide. I think I need an example with very specific instructions.

Thanks,

Hi rpomeroy,
Here is a link to devshare article that talks about how to make this happen:

Let me know if that solves your issue.

Maybe it is not answer for your answer. But it can help to anyone else. 
 
I build our Reporting portal by Maven. So I used maven for creating jar. 
 
1.to "dependencies" section I added all necessary libraries used by event handlers. For my projest is: 
 
<pre class='_prettyXprint _lang-auto _linenums:0'><dependency>
<groupId>org.eclipse.birt</groupId>
<artifactId>engineapi</artifactId>
<version>${birt.runtime.version}</version>
</dependency>

<dependency>
<groupId>org.eclipse.birt</groupId>
<artifactId>coreapi</artifactId>
<version>${birt.runtime.version}</version>
</dependency>

<dependency>
<groupId>org.eclipse.birt</groupId>
<artifactId>modelapi</artifactId>
<version>${birt.runtime.version}</version>
</dependency>

<dependency>
<groupId>org.eclipse.birt</groupId>
<artifactId>modelodaapi</artifactId>
<version>${birt.runtime.version}</version>
</dependency>

<dependency>
<groupId>org.eclipse.birt</groupId>
<artifactId>scriptapi</artifactId>
<version>${birt.runtime.version}</version>
</dependency>

</pre>
 
2. to "plugins" section I added 
<pre class='_prettyXprint _lang-auto _linenums:0'><plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.5</source>
<target>1.5</target>
</configuration>
</plugin>


<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<phase>prepare-package</phase>
<goals>
<goal>run</goal>
</goals>
<configuration>
<tasks>
<mkdir dir="target/MyReportingPortal/scriptlib"/>
<jar destfile="target/MyReportingPortal/scriptlib/MyReportingPortal.jar" basedir="target/classes"/>
</tasks>
</configuration>
</execution>
</executions>
</plugin></pre>
 
And birt libraries must be mavenized in your repository.
