ArcEngine/Java issue

ArcEngine 10.1 needs Java to be installed and ArcEgine finds Java by registry keys (not by environmental variables like JAVA_HOME and PATH).

When ArcEngine does not found Java properly there are two different error messages in the console log after Synchronized with "xxx" Map

1. Java Executable

    Loading jawt.dll failed. This is normal if java.version < 1.3. If java.version is > 1.4 and if this failure has occurred on Windows,
   
   please ensure that this program is started with a Java executable from a JDK/JRE install location on this computer.

2. Java HotSpot

How to fix

1. Install the Java that is included in the IMSMA^NG installation package
2. If Java already was installed;
   
   
   • find your Java version by typing Java -version in the Command window and click Enter.
   • Verify that the environment variable JAVA_HOME is set to C:\Program Files\Java\jre7 on 32-bits OS or C:\Program Files (x86)\Java\jre7 on 64-bits OS.
3. If none of the above fixed the problem, add ;%JAVA_HOME%\bin to the end of the PATH environment variable.
4. If it still does not work, test with the 5.08.04 solution:

   REASON
   ArcGIS 9.3.1 desktop is installed on the computer and there is a conflict between ArcObject versions.
   
   SOLUTION
   1. Make a copy of C:\IMSMAng\server\imsmaserver\lib\arcobjects.jar file.
   
   2. Copy the arcobjects.jar file from C:\Program Files\ArcGIS\java\lib to C:\IMSMAng\server\imsmaserver\lib.
   
   3. Restart the IMSMA server.
