Find Conversations not working

[girishghoda57]

Hi team @serious6 @OS-JaR @pkropachev @shibd @atamer, We used ews java api : <ews.java.api.version>2.1-SNAPSHOT</ews.java.api.version>

We call below code Collection<Conversation> folderConversations = exchangeService.findConversation( new ConversationIndexedItemView(10), new FolderId(WellKnownFolderName.Inbox));

But its threw below error The request failed. The expected XML node type was END_ELEMENT, but the actual type is START_ELEMENT.

Please help, we stuck on two days. Thank you

For any of user need help on it. The posted solution below:

1. First replace FindConversationResponse.java with below code `/*

import java.util.ArrayList; import java.util.Collection; import java.util.List;

/**

• Represents the response to a Conversation search operation. */ public final class FindConversationResponse extends ServiceResponse { List<Conversation> conversations = new ArrayList<Conversation>(); List<HighlightTerm> highlightTerms = new ArrayList<HighlightTerm>(); int totalCount;

/**

• Initializes a new instance of the FindConversationResponse class. */ public FindConversationResponse() { super(); }

/**

• Gets the results of the operation. */ public Collection<Conversation> getConversations() {

return this.conversations;

}

/**

• Gets the results of the operation. */ public Collection<HighlightTerm> getHighlightTerms() {

return this.highlightTerms;

}

/**

return this.totalCount;

}

/**

reader.readStartElement(XmlNamespace.Messages,
    XmlElementNames.Conversations);
if (!reader.isEmptyElement()) {
  do {
    reader.read();
    if (reader.getNodeType().getNodeType() == XmlNodeType.START_ELEMENT) {
      Conversation item = EwsUtilities.
          createEwsObjectFromXmlElementName(Conversation.class,
              reader.getService(), reader.getLocalName());

      if (item == null) {
        reader.skipCurrentElement();
      } else {
        item.loadFromXml(
            reader,
            true, /* clearPropertyBag */
            null,
            false  /* summaryPropertiesOnly */);

        conversations.add(item);
      }
    }
  }
  while (!reader.isEndElement(XmlNamespace.Messages,
      XmlElementNames.Conversations));
}
reader.read();

if (reader.isStartElement(XmlNamespace.Messages, XmlElementNames.HighlightTerms) &&
    !reader.isEmptyElement())
{
    do
    {
        reader.read();

        if (reader.getNodeType().getNodeType() == XmlNodeType.START_ELEMENT)
        {
            HighlightTerm term = new HighlightTerm();

            term.loadFromXml(
                reader,
                XmlNamespace.Types,
                XmlElementNames.HighlightTerm);

            this.highlightTerms.add(term);
        }
    }
    while (!reader.isEndElement(XmlNamespace.Messages, XmlElementNames.HighlightTerms));
}

if (reader.isStartElement(XmlNamespace.Messages, XmlElementNames.TotalConversationsInView) && !reader.isEmptyElement())
{
	this.totalCount = Integer.parseInt(reader.readElementValue());
  reader.read();
}

if (reader.isStartElement(XmlNamespace.Messages, XmlElementNames.IndexedOffset) && !reader.isEmptyElement())
{
	this.totalCount = Integer.parseInt(reader.readElementValue());
	reader.read();
}

} } `

2. Create file name "HighlightTerm" in package microsoft.exchange.webservices.data.property.complex and paste below code: `package microsoft.exchange.webservices.data.property.complex;

import microsoft.exchange.webservices.data.core.EwsServiceXmlReader; import microsoft.exchange.webservices.data.core.XmlElementNames;

public class HighlightTerm extends ComplexProperty {

private String scope;

private String value;

public HighlightTerm() {
	
}


/**

• Tries to read element from XML.
• @param reader The reader.
• @return true, if successful
• @throws Exception the exception */ @Override public boolean tryReadElementFromXml(EwsServiceXmlReader reader) throws Exception {

if (reader.getLocalName().equals(XmlElementNames.HighlightTermScope)) {
  this.scope = reader.readElementValue();
  return true;
} else if (reader.getLocalName().equals(XmlElementNames.HighlightTermValue)) {
  this.value = reader.readElementValue();
  return true;
} else {
  return false;
}

}

}`

3. Add extra properties name in XmlElementNames.java public static final String HighlightTerms = "HighlightTerms"; public static final String HighlightTerm = "Term"; public static final String HighlightTermScope = "Scope"; public static final String HighlightTermValue = "Value"; public static final String TotalConversationsInView = "TotalConversationsInView"; public static final String IndexedOffset = "IndexedOffset";

It resolves "The request failed. The expected XML node type was END_ELEMENT, but the actual type is START_ELEMENT." error for findConversation().

I got this solution from .NET repository. Thank you.
