Problem at Startup of Agentry Server

[Former Member]

I have followed the instructions from the PDF "How-to Build an Agentry Based Mobile App from Scratch Connecting to an SAP Back-end Part 1" and I have searched online for a solution, including various threads in this forum. But I still get this error when starting the Agentry server:

BackEndInitError (Java Back End - NoClassDefFoundError|java.lang.NoClassDefFoundError: com/syclo/sap/Server), at java.lang.ClassLoader.defineClass1(Native Method)

Failed to init Java Back End (Java v6.1.0.3 (JVM version 1.7.0, AJAPI version  build )) from ag3javabe.dll

I have all JARs and DLLs in the server directory, my Agentry.ini parameters are:

classPath=./Java/SapCommon-130881.jar;./Java/ZFlightBooking.jar;./Java/Agentry-v5.jar;./Java/ini4j-0.4.1.jar;./Java/sapjco.jar;

serverClass=com/syclo/sap/sflight/server/Server

As you can see my classPath is correct (and I use the same files from this folder as build path in Eclipse):

Jurgen,

You classpath matches mine so as you mention you should be good there.  Plesae take a look at my response on the following thread.

You will want to make sure you have updated your SAPCommon or you will end up with that error.   I am assuming you are using the SAPCommon from the SMP 2.3 SDK which has this error in it.

Let me know if you are still having problems after checking your SAPCommon jar file.

Hi Bill,

Now I get this error:

(Java Back End - NoClassDefFoundError|java.lang.NoClassDefFoundError: serverClass=com/syclo/sap/sflight/server/Server

), Caused by: java.lang.ClassNotFoundException: serverClass=com.syclo.sap.sflight.server.Server

No idea why, I didn't change the Agentry.ini. I have even rebuilt the ZFlightBooking.jar

Can you check your events.log file and post the error details.  It should include a stack trace that might give us some more details about what the underlying issue is.

[jason_latko · Accepted solution]

ZFlightBooking.jar must not have the com/syclo/sap/sflight/server/Server class where you expect?  You are also getting a socket address in use error, usually caused by the same port being used in your Agentry.ini or JavaBE.ini files for multiple functions.

Jason Latko - Senior Product Developer at SAP

I have fixed the socket error, one Angel port was listed twice in Agentry.ini

But the class should be there:

[bill_froelich · Accepted solution]

Looking at your class path I suspect the problem is that you are using sapjco3.   The SAPCommon jar you are using is built on JCo2 so you will need to include the older jco libraries for it to work.  I suspect the missing class is coming from within the Server class as it tries to load the Jco2 classes.

Please try with the previous version and let us know the results.

--Bill

[Former Member · Accepted solution]

I have no Idea where this sapjco3.jar at the start of the log class path is comming from. My agentry.ini only contains the sapjco.jar you can see at the end of the path. Here is my complete Agentry class path again:

classPath=./Java/SapCommon-130881.jar;./Java/ZFlightBooking.jar;./Java/Agentry-v5.jar;./Java/ini4j-0.4.1.jar;./Java/sapjco.jar;

And I don't have the sapcjo3.jar file in my Agentry folder.

edit: found it, was a system environment variable. Didn't help though.

[bill_froelich · Accepted solution]

Nor sure where that would come from either.  Perhaps there as a CLASSPATH envinronment variable that is being picked up.

Here is the classpath from my Agentry.ini for the FlightBooker tutorial.

classPath=.\Java\Agentry-v5.jar;.\Java\ini4j-0.4.1.jar;sapjco.jar;.\Java\ZFlightBooking.jar;.\Java\SAPCommon-130881fixed.jar;.\Java

Maybe try re-ordering the jar files to see if that makes any difference.  Can you also send me your SAPCommon jar so I can test on my setup to see if that might still be the issue?

Please make sure your ServerClass line on the Agentry.ini is correct, and does not have "ServerClass=ServerClass=com/syclo/sap/sflight/server/Server"

Yes, thanks, I had noticed that too. It solved this error, but only for the next to appear.

Jurgen,

I tested my server using your SAPCommon jar and it started fine.  I also compared my JavaBE with yours and have a difference in the [SERVICE LOGIN] section.  Not sure if that makes any difference or not but worth a try.

Going off of what bill said, I do see you have "==" on UID" and "UPASSWORD" keys.  Please make sure to only have one "=" as the second one will be added onto the username and password.

Thanks for the tips, they probably save me from future problems. But this particular error persists.

@Bill: I have tried your jar, didn't work either.

[Former Member · Accepted solution]

The issue was an invisible sign at the end of javabe.ini after copy-pasting the wrappers from the PDF.

Hi Experts,

I am following the document at How-to Build an Agentry based mobile app from scratch connecting to an SAP back-end Part1 and I have followed all the steps as suggested in the document.

I am using Agentry Server 6.0 here.

In order to plug in my custom java code, I have exported my Java project and added under ClassPath variable under Server's Agentry.INI file.

classPath=./ini4j.jar;./sapjco.jar;./Java/Agentry-v5.jar;./Java/SAPWM-5.3.0.0.jar;./Java/SAPCommon-122971.jar;./Java/ZFlightBooking.jar;./Java;

I have given the serverClass path as : serverClass=com/syclo/sap/sflight/server/Server

While starting the server, I get the following error:

Exception: 01:37:26 03/15/2014 : 20 (Agentry3), BackEndInitError (Java Back End

- NoClassDefFoundError|java.lang.NoClassDefFoundError: com/syclo/sap/sflight/ser

ver/Server|classpath = .;C:\Program Files (x86)\Java\jre7\lib\ext\QTJava.zip;.\J

ava\Agentry-v5.jar), javaBE.cpp#407:JavaBackEnd::init

I can confirm that the required DLL files are present under the ServerDev directory.

Init4j and sapjco are present under ServerDev directory.

SAPWM, SAPCommon , Agentry V5 and ZFlightbooking are present under ServerDev/Java directory.

I have also tried all possible combinations  including  editing the standard "Classpath" and "Path" variables under "Environment Variables" too, and added the path to this JAR file, but nothing seems to be working.

Request your advice on the same.

The class path in your exception doesn't have ZFlightBooking.jar (and several other JARs), so probably the class path in your Agentry.ini is somehow not working correctly.

Jurgen,

I could be wrong as I have not gone through this flight tutorial, but I believe your serverClass is wrong in your Agentry.ini.

You have - serverClass=com/syclo/sap/sflight/server/Server

But should be - serverClass=com/syclo/sap/sflight/Server

Hi Jason,

thanks for the answer, but the serverClass is correct. The packages is named com/syclo/sap/sflight/server with the class Server, so combined it is com/syclo/sap/sflight/server/Server

Jurgen,

OK, sorry about that.  We don't keep the product Server classes in the server package, so it jumped out at me as looking strange.  I guess the flight tutorial is set up differently as you say.
