For the system and software information: OS : Ubuntu 10.04 kernel 2.6.32-30 IDE : SpringSource Tool Suite 2.5.2.SR1 Caused by: java.lang.NullPointerException
at com.google.gdata.client.Service.<clinit>(Service.java:97)
... 75 more
Could you check if this exception occurs when the API is used out of BIRT?
I created a test class that uses my google analytics service class. I debugged the Service.class and didn't get an exception. I can get the AnalyticService object. (In reply to comment #2) > Caused by: java.lang.NullPointerException > at com.google.gdata.client.Service.<clinit>(Service.java:97) > ... 75 more > > Could you check if this exception occurs when the API is used out of BIRT? Birt's logic for using external jar/class files is basically explained ot its site: http://wiki.eclipse.org/BIRT/FAQ/Scripting: "If you are using the BIRT Designer, you have to add your classes to the classpath of the BIRT Viewer Plugin: org.eclipse.birt.report.viewer. To do this you have two choices: ... 2. Package your classes into one or more jar-files and put them into the birt/scriptlib subfolder of the Viewer-plugin. ... so, what am i missing or what is special for Google Analytics libraries? We have checked in a patch to resolve this issue in in 2.6.3 and 2.7. You can get the latest fix from org.eclipse.birt.core/src/org.eclipse.birt.core.framework.URLClassLoader.java. Just recompile this class and replace the old one in your lib/coreapi.jar and plugins/org.eclipse.birt.core.jar. Please let us know if it resolve your issue. Hi, I just left the office, i will try to reproduce the error and apply your patch in the weekend on my local PC, otherwise i will let you know on Monday latest when i have access to my development PC, sure. Thank you very much for your effort. (In reply to comment #5) > We have checked in a patch to resolve this issue in in 2.6.3 and 2.7.

This is silly but i can't open the patched class link; Could you please give it one more time? Created attachment 194398 [details]
org.eclipse.birt.core\src\org\eclipse\birt\core\framework\URLClassLoader.java
I recompiled the patched URLClassLoader.java and placed in org.eclipse.birt.core_VERSION.jar (under eclipse plugins) but didn't modify lib/coreapi.jar (actually i couldn't find it). Your patch worked for me. Now i can preview my report in any format. It resolved my issue. Thank you very much.

I will explain a bit more the steps. Recompile the patched (and attached file ın comment #8). Copy all the generated class files under your eclipse plugins (in my case ~/software/springsource/sts-2.5.2.SR1/plugins/org.eclipse.birt.core_2.6.2.r262_v20110209.jar) and int that jar under '/org/eclipse/birt/core/framework/' directory( you will see old versions of these classes).

Hi, I'm trying to use Google Analytics API to get the data for the scripted data source of my report. I created a Java Project and in it; one domain class and one service class to pull the data from ga API. I can fetch the data in my service. In the same project, i created a new report and chose 'scripted data source' as data source. I also created output columns, in the dataset. I wrote the scripting code for 'open' and 'fetch' by using my service class. In the `preview results` of the data set i can view the data pulled from my applications google analytics. But in the designer 'preview' (and the other output formats under eclipse->run-> View Report) i got the exception below. (i didn't quote the class codes, because i can fetch the data successfully until the data set preview results) i put the necessary libraries in the classpath of my java project but the birt viewer cannot initialize the analytics service so throws NPE and ExceptionInInitializerError. (That's what i see in the stacktrace - below) classpath: _______________________________> <?xml version="1.0" encoding="UTF-8"?> <classpath> <classpathentry kind="src" path="src"/> <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.6"/> <classpathentry kind="lib" path="lib/activation.jar"/> <classpathentry kind="lib" path="lib/gdata-analytics-2.1.jar"/> <classpathentry kind="lib" path="lib/gdata-analytics-meta-2.1.jar"/> <classpathentry kind="lib" path="lib/gdata-client-1.0.jar"/> <classpathentry kind="lib" path="lib/gdata-client-meta-1.0.jar"/> <classpathentry kind="lib" path="lib/gdata-core-1.0.jar"/> <classpathentry kind="lib" path="lib/gdata-docs-3.0.jar"/> <classpathentry kind="lib" path="lib/gdata-docs-meta-3.0.jar"/> <classpathentry kind="lib" path="lib/gdata-media-1.0.jar"/> <classpathentry kind="lib" path="lib/google-collect-1.0-rc1.jar"/> <classpathentry kind="lib" path="lib/jsr305.jar"/> <classpathentry kind="lib" path="lib/mail.jar"/> <classpathentry kind="lib" path="lib/servlet-api.jar"/> <classpathentry kind="output" path="bin"/> </classpath> After making a deep search in Google on this issue, i tried to put the libraries under: - Report Designer -> Property Editor - Report-> Resources -> Jar Files - Eclipse birt plugin scriptlib (in my case under ~/software/springsource/sts-2.5.2.SR1/plugins/org.eclipse.bi rt.report.viewer_2.6.2.r262_v20110214/birt/scriptlib) - Eclipse birt plugin WEB-INF/lib directory (in my case~/software/springsource/sts-2.5.2.SR1/plugins/org.eclipse.birt.report.viewer_2.6.2.r262_v20110214/birt/WEB-INF/lib) None of these worked for me. I don't know the difference between the 'data set - preview results' and 'designer viewer'. I created another threads on this issue on birt-exchange forum: This one includes all my classes : http://www.birt-exchange.org/org/forum/index.php/topic/22184-google-analytics-api-as-a-scripted-data-source/page__p__76410&#entry76410 This thread is also related and gave some ideas but not a workaround.: http://www.eclipse.org/forums/index.php?t=msg&th=200425&S=68ff3f9bf4f04ae6ba19267a0573164f#msg_639706 ExceptionInInitializerError is thrown on the line: "...
