Can't run Annotation java sample

jane.gu · December 14, 2015, 12:09am

I have downloaded GroupDocs.Annotation java samples, but can’t run it.

It has compile errors on AnnotationServlet line 142, 146:

141 if (connector instanceof ICustomConnector){

142 ((ICustomConnector)connector).setEnvironmentCreator(annotationHandler);

143 }

144 // This callback will be called for each case when collaborator should be created

145

146 annotationHandler.setCollaboratorCallback(new ICallback<Pair<Integer, Color>, Pair<IUser, IDocument>>() {

@Override

public Pair<Integer, Color> onCallback(Pair<IUser, IDocument> param) {

// User collaborator for document will be created with returned access rights and color

// Default CollaboratorCallback is made similarly

return new Pair<Integer, Color>(AccessRights.All.value(), Color.red);

}

});

If i comment out those two parts,

It throws “java.lang.NullPointerException
at com.groupdocs.annotation.samples.javaweb.IndexServlet.doGet(IndexServlet.java:38)”. when i run this web application.

Hello,

Thank you for your inquiry.

Please don't comment these two lines of code, this sample should works well without any comments. Could you please share with us your full stack trace of the error and we will investigate it. Also please share with us additional information about your environment:

1. Tomcat version that you use

2. Java version

3. Your Application.properties file

We will wait for these details and will be glad to help you.
