Vinod Kannur created OLINGO-1127:
------------------------------------
Summary: SAP 1q and 2q are not supported in Apache Olingo
Key: OLINGO-1127
URL: https://issues.apache.org/jira/browse/OLINGO-1127
Project: Olingo
Issue Type: Bug
Components: odata2-core
Affects Versions: V2 2.0.7, V2 2.0.6
Environment: OS- Windows 10, Java J2EE, Eclipse
Reporter: Vinod Kannur
The accept language for 1q and 2q is not supported in Olingo.
Please refer SAP documentation
https://help.sap.com/saphelp_nw74/helpdata/en/91/f21f176f4d1014b6dd926db0e91070/content.htm
The batch request contains Accept Language <b> en-US-x-sappsd </b>
Content-Type: application/http
Content-Transfer-Encoding: binary
GET UserSettingsSet HTTP/1.1
sap-contextid-accept: header
Accept: application/json
Accept-Language: en-US-x-sappsd
DataServiceVersion: 2.0
MaxDataServiceVersion: 2.0
sap-cancel-on-close: true
I debugged and found that AcceptParser class would check the language against
the REGEX which fails and throws an exception.
public List<String> parseAcceptableLanguages() throws BatchException {
return parseQualifiedHeader(acceptLanguageHeaderValues,
REG_EX_ACCEPT_LANGUAGES_WITH_Q_FACTOR,
BatchException.INVALID_ACCEPT_LANGUAGE_HEADER);
}
We use pom version 2.0.6 for Olingo in our productive code and I also tried in
2.0.7 version, which gives the same error.
package org.apache.olingo.odata2.core.batch;
import java.util.ArrayList;
import java.util.List;
import java.util.TreeSet;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
import org.apache.olingo.odata2.api.batch.BatchException;
import org.apache.olingo.odata2.api.exception.MessageReference;
/**
*
*/
public class AcceptParser
private static final Pattern REG_EX_ACCEPT_LANGUAGES = Pattern
.compile("((?:(?:[a-z]{1,8})|(?:\\*))\\-?(?:[a-zA-Z]{1,8})?)");
Since 1q and 2q are valid intermediate SAP languages which is used for
translation, batch request should accept those languages.
Thanks,
Vinod.
