I am trying to migrate GWT/Datanucleus JDO project to Google Cloud and ran into the following when trying to enhance. I didn't change anything from GAE setup:
DataNucleus Enhancer (version 3.1.1) : Enhancement of classes
Sep 08, 2018 3:48:29 PM org.datanucleus.util.Log4JLogger
SEVERE: L:115 > Parser error with file "file:/C:/Users/xxxx/AppData/Local/Temp/enhancer-4720720665984377371.flf" has cause

SEVERE: L:115 > Parser error with file "file:/C:/Users/xxxx/AppData/Local/Temp/enhancer-4720720665984377371.flf" has cause
Error reading the Meta-Data input "Content is not allowed in prolog.
org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 1; Content is not allowed in prolog.
It makes sense since the file referenced (the flf file generated by DN Enhancer) is not in XML format for some reason:
C:\b\src\bt\sh\package.jdo
C:\b\src\bt\sr\sec\package.jdo
C:\b\war\WEB-INF\classes\bt\sh\package.jdo
C:\b\war\WEB-INF\classes\bt\sr\sec\package.jdo
My question is: why is enhancer generating non-xml then tries to read it as xml out of a sudden? I have latest 4.0.1 Datanucleus Eclipse Plugin. What's the solution?

I am also receiving same error, strange here is, application is working on local tomcat 9 but it's not working on tomcat 9 which has installed on ubuntu.
The difference observed that, on local jersey version 'jersey : 1.18' but on ubuntu jersey version taking as 'jersey:1.9', where could I find the jersey version ? I just simply generating .war file and copying on webapps folder in tomcat.
Please advise what dependencies or what went wrong here..
I ran the mvn war:war in the command prompt, I then went to upload to appengine using appcfg update and I got this error. The app works on localhost. Aside from the path simply being wrong, there is no appengine-web.xml. Any help would be appreciated thankyou.

The latest version of the mirror-quickstart-java that supports Google App Engine has been tagged with app-engine; you should use this specific release.
I am having difficulty getting to the starting line on my machine.
1) Windows 7 32bit all service packs installed
2) Installed JDK 1.7.0_21
3) Checked PATH that only one copy of JDK\bin is in path and that it is correct.
4) Installed Eclipse Juno Java bundle. eclipse-java-juno-SR2-win32.zip
5) Install Google App Engine SDK per the tutorial using:
https://dl.google.com/eclipse/plugin/4.2
Selected:
- Google Plugin for Eclipse
- GWT
- SDK
Did NOT select:
- Developer Tools (Android)
- Google App for Android
- NDK Plugins
6) Following the tutorial, pull down the Google Icon and select "New Web Application Project"
- Name it Guestbook as shown
- Uncheck GWT
- Check Google App Engine
- Finish
7) Following the tutorial, Run as Web Application
At this point, the console shows several successful steps and then crashes and burns with jetty unable to establish a loop back connection. The full console output is attached below. I have searched all over the web and have not been able to find anything. I checked PATH and JDK. I checked the Windows firewall rule for Eclipse, it looks OK. I looked at the Classpath tab but could not see anything obviously wrong (although I don't know what it is supposed to look like)

PROBLEM SOLVED!
I was able to absolutely nail the cause of this problem and fix it.
What I did was removed the JRE and JDK from "C:\Program Files\Java\" (which is where Oracle's installer puts them by default) and reinstalled them in "C:\Java\Java7\" Apparently something in Eclipse and/or the Google Android development kit is still sensitive to spaces in the pathname to the JDK. This is an ancient general problem with Eclipse reported around 2005.
I did NOT need to drop down to Java 6
I did NOT need to edit Eclipse.ini and add a -VM line
I did NOT need to manually add the path to the jdk to PATH
Hope this helps the next person because this is an incredibly frustrating problem when you encounter it.
Thanks!
David Hetherington
Problem: Trying to run the 'Hello World' app using google eclipse plugin (eclipse - Kepler).
Solution: Adding to David's answer. If you have multiple jre's installed make sure the jre you are pointing to does not have a space in the absolute path. To change the jre you are pointing to go to eclipse - window->preferences->server->runtime environments->google app engine->edit. Now check the jre version you are pointing to. In my case I had jdk 1.7 installed in Program Files/Java and jre6 and jre7 installed in the same location. I moved jdk 1.7 to Program_files but was still getting the loopback error. Followed the above steps and pointed the jre version to the one in jdk1.7/jre in Program_files/java as earlier it was pointing to C:/Program Files/java/jre7
Hope this helps someone.
Are you sure you don't have anything else running with the same PORT number as the web-application? Default webapplication PORT is 8888
I am not using eclipse, using GAE SDK to upload my project, problem is when i am trying to upload it is using jre not jdk thats the reason i am getting below error, please help how can i force app engine sdk to use JDK instead of jre

Personally I have intentionally set it up to use the JRE from within the SDK by modifying appcfg.cmd to
"%JAVA_HOME%\bin\java" -Djava.home="%JAVA_HOME%\jre" -Xmx1100m -cp "%~dp0\..\lib\appengine-tools-api.jar" com.google.appengine.tools.admin.AppCfg %*
and setting JAVA_HOME to point to the JDK.
I am guessing you could modify -Djava.home="%JAVA_HOME%\jre" to point to wherever you like.
Got this error. Any idea how to get rid of it?
Yesterday it was working fine but today I got these errors. I saw a known issue with this - link. But I didn't find any solution yet..

If you are using Java 8 in your app engine application, you will need to include
<url-stream-handler> urlfetch </ url-stream-handler>
in appengine-web.xml.
appengine-web.xml Reference
I am assuming that you are seeing this in your Eclipse IDE when you are trying to run the Eclipse Project as a Web Application.
The GAE plugin simply checks if there is an updated AppEngine SDK available for download. If there is a newer one than the one you are currently using then it lets you know that. The error is because at that instance, there was probably a network error and it got not connect through. It is harmless as far as running your application is concerned.
But if your application is dependent on accessing some external network services, then chances are that they might fail also if the network issue persists in your development environment.
got it working.. : cmd->goto your home directory >mkdir .appcfg_no_nag this will stop checking for the update and yourweb app willrun locally atleast..
This error is related to internet connection. I changed to other connection, it works
You should add in appengine-web.xml:
<url-stream-handler> urlfetch </ url-stream-handler>
And also start using java.net.URLConnection,
Apache HttpClient is not gonna work for example.
