Re: T 5.2 & App Engine 1.3 SDK
Hey Alex (or Dmitry),
I'm trying to get a T5.2 + 1.3GAE project working too.
How did you perform the fix in Dmitry's solution?
(http://dmitrygusev.blogspot.com/2009/10/develope-java-applications-with-gae-sdk.html)
You mention replacing the agent in the jar file - but I thought Dmitry's fix was to simply add it to your project.
I tried to add it to my project, but I can't get the GAE dev to notice it - I keep getting the same issue with the LocalVariableTable.
I was previously thinking it might be related to some of the GAE jars I have on the classpath from the unit testing - but when I saw your wording in this email I didn't understand what jar you were editing. Any thoughts?
Thanks!
Michael Leonardo

Dmitry,
indeed, it works w/ the javaagent fix; however, I had to do something
slightly different than what you had:
When I was running it w/ the agent that you had on the blog, after
replacing the agent in the jar file, I was getting a message that the agent
was missing a "premain" class:
Exception in thread "main" java.lang.NoSuchMethodException:
com.google.appengine.tools.development.agent.AppEngineDevAgent.premain(java.lang.String,
java.lang.instrument.Instrumentation)
at
java.lang.Class.getMethod(Class.java:1605)
at
sun.instrument.InstrumentationImpl.loadClassAndStartAgent(InstrumentationImpl.java:294)
at
sun.instrument.InstrumentationImpl.loadClassAndCallPremain(InstrumentationImpl.java:338)
FATAL ERROR in native method: processing of -javaagent
failed
Thus, I had to add an empty premain() method to get it to work.
Here's my agent class just in case anyone is interested:
package com.google.appengine.tools.development.agent;
import java.lang.instrument.Instrumentation;
/**
*
* @author polrtex
*/
public class AppEngineDevAgent {
public static void premain(String foo, Instrumentation bar) {
}
}
Cheers,
Alex K

Hey Dmitry,
I found out that the GAE dev_appserver.sh script runs KickStart which will add the javaagent automatically. To NOT include a javaagent I had to remove that command from the script. Then the only way I could get it to see the replacement AppEngineDevAgent was to create a jar and include in via the -javaagent VM argument. Now it's finally working. Your blog was incredibly useful. Thanks for your help!

Ah, figured out that the javaagent was being added after I switched to using the dev_appserver script.
Even so, I now get the "Unable to locate the App Engine agent" message that I should be getting - but it's not finding it in my application. Thoughts?
