How to call a java method in birt

Hi all,

I am very new to birt. I have designed a class that parses a log file into comma separated values. Now I need to generate a report that calls the method parserMethod() of this class and generats a report. The method has two parameters logfilepath and date.
I need to know how do I call this method from BIRT so that it uses the output from this class as its data set.

Have a look at Scripted DataSets. They can be used to call a Java method that delivers data for a data set.
The official tutorial can be found here: http://download.eclipse.org/birt/downloads/examples/scripting/scripteddatasource/scripteddatasource.html

The tutorial is old but still works. You should keep Java files in separate Java Eclipse projects. To be able to access Java classes living in another project from within your reports you have to tell the report where to look for java class files. Prior to BIRT 2.5.2 BIRT was searching all the projects in your workspace for the corresponding java classes. Starting with BIRT 2.5.2 you have to announce corresponding java projects to your report project manually. To do such have a look at: http://birtworld.blogspot.com/2009/12/birt-designer-classpath-changes.html

hope this helps

Thanks Chris.

I have done the same but I am getting an error while I am trying to preview the rpt.

The following items have errors:

ReportDesign (id = 1):
+ There are errors evaluating script "parserObject = new FilePaser();
valueObject = parserObject.parserMethod(LogFilePath, ProcessingDate);
totalrows = valueObject.size();

I am using standalone BIRT Report Dsigner ver 2_3_0 and not the one in eclipse. Also in
C:\birt-rcp-report-designer-2_3_0\plugins\org.eclipse.birt.report.viewer_2.3.0.v20080606\birt\WEB-INF\
folder ther is no classes folder so I hav pastd my class file in LIB folder.

The error you are seeing says that it can't find the java class you are attempting to use.
I forgot to mention that there are several conventions when using Java inside of Rhino Code (in BIRT you re programming in Rhino)
So the problem is already in line 1 with this statement:
parserObject = new FilePaser()

When trying to access a Java class inside of Rhino you have to qualify the java class using the package name and adding the word Packages in front of it.
Let's say the FileParser class is located in package de.something you have to change the first line to
parserObject = new Packages.de.something.FileParser();
You always have to use this notation when trying to access Java classes!

In Rhino there is something like a import statement in Java that can import packages only. So if you want to use several classes that are located in de.something package you could simply write:
importPackage(Packages.de.something)
parser = new FileParser();

Please keep in mind that the importPackage statement in Rhino can only import packages and is not able to import single classes. This means that the statement:
importPackage(Packages.de.something.FileParser) will throw a error because it's a class and not a java package.

I have put my file in the workspace of BIRT. I have tried doing this by modifying the first line as

parserObject = new Packages.FilePaser();

but it still doesn't work. What is the default package in which it searches for a class. Have tried putting the class in \birt\WEB-INF\classes and also in \birt\WEB-INF\lib but none of them are working.

Also I have one more thing to ask
my method thakes two arguments as :
valueObject = parserObject.parserMethod(LogFilePath, ProcessingDate);
These two arguments are the report paramters that are taken as i/p. Can I access these report parameters as shown above.

Hi,

the first thing you should try to achieve is that your report runs in the Eclipse BIRT Designer without any issues. After that you should build a jar file out of your java project. This jar file has to be put into the scriptlib dir of the WebViewer installation. The scriptlib dir is a special direction that can be configured using the web.xml of the webViewer application. The default is a directory called scriptlib inside the webviewer application.

If you are using the BIRT Designer standalone you should switch to the eclipse one. I m not sure if the Designer standalone is able to address class files because of the way it is currently build.
It might help to build the java project as a jar file and put it into the scriptlib folder located somewhere under the plugins directory.

concerning your second question:
Yes that's possible. You can reference a parametervalue using params["myParameterName"].value to get what the user has provided for parameter named myParameterName. Just make sure that the parameters have correct types.
