PDA Coldboot whit Creme 328

[Former Member]

Hi all,

we are trying to do a Coldboot in the device Intermec CN3 using SAP MI 25 SP 18 Client and JVM Creme 'CrEme328 ARM CE50 PPC'.

The first step was using the manufacturer jar file 'Device.jar', we instance in the servlet, a object of the class:

import com.intermec.device.*;

***************

Power.warmboot(); // warm boot CN3

and then, we added the path in file 'creme_listOfJars.txt' :

-classpath 'SD CardMIwebappsMAM25_ECLIPSEWEB-INFlibDevice.jar;

This procedure didn´t reboot the device, and no messages of error were displayed.

The next step, we decide use a JNI call using a manufacturer DLL ''CN3ColdResetJNI_DLL.dll', in the servlet, we load the 'dll' file

and call the function to coldboot:

System.loadLibrary("CN3ColdResetJNI_DLL.dll");

DoColdBoot();

We tried put the dll in differents locations, calling with complete path, without extension, etc. and didn´t work, and no

messages were displayed.

Have anybody any idea about this issue, or know another case, with the same problem?

Support Creme JNI methods inside Tomcat?

Regards.

Hi,

why do you put a JAR file into the listofjars file, that is basically inside MAM? Why do you not put it inside the LIB folder of MI then? Can be downloaded as an AddOn in this case.

Jni is supported in Creme. So this should work fine a swell.

So: why is a restart necessary for you? MI has the option do do that after downloading new add ons. You just need to describe that in the deployment descriptor for the installation toolkit. While you have installed MAM - you should use DB2e - the DB2e installer does a restart of MI after its installation. Look into the XML file there and you will find the correct values.

Hi Satur,

SAP does not support creme 3.28, you will have to use 3.27

Hello Saturn:

Why do you need to do a coldboot?
