in step 2 when I click next an error message occurs : "The selected wizard could not be started.

Plug-in "com.google.gdata" was unable to instantiate class "com.google.gdata.devtools.eclipse.ui.NewProjectWizard?". java.lang.NullPointerException?

Please file it as an issue with details of the problem, OS and Eclipse version. We'll carry it forward from there.

I use ubuntu 9.04 and eclipse 3.2.2 eclipse works fine and i'm trying to install the google data plug-in following your instruction. but after restart eclipse there isn't "google data" folder in "new->other" menu. what is the problem? can you help me? there is a screenshoot thank you.

This plug-in requires Eclipse v3.3 or above. The requirements are listed on the Installation wiki.

Please, i need help. When i tried to execute the class, i had the follow error message:

Exception in thread "main" java.lang.NoClassDefFoundError: 
	at Documents.main(Documents.java:36)
Caused by: java.lang.ClassNotFoundException: com.google.common.collect.Maps

Thanks for help

A gdata dependency on two jars found in the "deps" folder of the java gdata download was introduced a month or two ago. Add these two jars to your classpath and you will be good to go. The particular Maps class you are looking for is found in the google-collect-1.0-rc1 jar, which is one of those two dependencies.

Cheers.

Hi,

After setting the Classpath with the specified Jars also, i am getting the same exception as Mr.Toniazzom. Could you please help me?

Exception in thread "main" java.lang.NoClassDefFoundError?: com/google/common/collect/Maps

at com.google.gdata.wireformats.AltRegistry?.<init>(AltRegistry?.java:118) at com.google.gdata.wireformats.AltRegistry?.<init>(AltRegistry?.java:100) at com.google.gdata.client.Service.<clinit>(Service.java:532) at Documents.main(Documents.java:36)

This is My Classpath: (both UserVariables? and System Variables are set)

%JAVA_HOME%\lib;D:\GDataApp\gdata-samples.java-1.39.0\gdata\java\deps;.;

I tried giving the Classpath till the Jars as below: %JAVA_HOME%\lib;D:\GDataApp\gdata-samples.java-1.39.0\gdata\java\deps;D:\GDataApp\gdata-samples.java-1.39.0\gdata\java\deps\jsr305.jar;D:\GDataApp\gdata-samples.java-1.39.0\gdata\java\deps\google-collect-1.0-rc1.jar;.;

I also tried copying the google-collect-1.0-rc1.jar and jsr305.jar onto my External Jars Location(which we give at the time of creating the Project). Even then also i got the same problem.

Could you please suggest me some solution for this?

Thanks in advance, Ravindanath Y

i dont know what is the problem

everytime i try to run this i found this error

ppppplllllllllllllllllllllllllllllllllllllz help

I'm having the same problem too. Within Program Arguments are you passing the following arguments: arg0? = username arg1? = password. Reading Eclipse for dummies it says that you can put the username and password seperated by a space in the Program arguments and it will automatically associate arg0? with the first entry and arg1? with the second entry.

Hi, You seems to be missing the some core components in your path. This includes "google-collect-1.0-rc1.jar" and "jsr305.jar". Ensure you have these two required jars, rebuild and try again...

They are both available within the "deps" folder of the "Google Data Java Client Library". You can get the latest gdata library here... http://code.google.com/p/gdata-java-client/downloads/list

I run this project as "java application", could you show me how to configure 'run configurations', thanks!

I have resloved this question, lack of google-collect-<version>.jar, "add external jars" this jar, it works well.

Thanks weiwenxing..

If you are using Eclipse, on your "Referenced Libraries" add external jars to the list and you will be okay
