Hi,
In createContents() method, i have just following lines of code.

@Override
protected void createContents(Composite parent)
{
Text textField = new Text(parent, SWT.BORDER);
new AutoCompleteField(textField, new TextContentAdapter(), new String[]
{"abc", "aef","rem","ret","jkl","jre"});

}

I am getting this error:

java.lang.NoClassDefFoundError: org/eclipse/core/runtime/ListenerList
at org.eclipse.jface.fieldassist.ContentProposalAdapter.<init>(ContentProposalAdapter.java:1215)
at org.eclipse.jface.fieldassist.AutoCompleteField.<init>(AutoCompleteField.java:49)
at com.logwebui.test.BasicEntryPoint.createContents(BasicEntryPoint.java:123)

Please help me in this regards.

I was able to resolve the issue. I added jar org.eclipse.core as reference. But I am facing new issue. When I enter text in this autocomplete textfield, I get following excpetion:
java.lang.SecurityException: class "org.eclipse.jface.dialogs.Dialog"'s signer information does not match signer information of other classes in the same package

and

java.lang.ExceptionInInitializerError at org.eclipse.jface.fieldassist.ContentProposalAdapter.openProposalPopup(ContentProposalAdapter.java
I don't understand how to resolve this.

You get this exception when you mix signed and unsigned bundles that
export the same package, for example a (signed) rap release version and
an (unsigned) filedialog nightly build from the incubator.
