deploytool problems and incompatible JVM.

hi, change the JVM version of matlab for my computer, I use windows 7, and is installed matlab ml2013a, both 64 bits.

the root of the problem is that I try to deploy an application in java and threw the following error:

3 errors 8 warnings Error: An error occurred while shelling out to javadoc (Error code = 1). Unable to build executable.

such error to me was hard to track, and alleged that I found only solution to the problem was to change the JVM matlab for compatibility with windows. and java version on my computer is:

java version "1.8.0_20" Java (TM) SE Runtime Environment (build 1.8.0_20-b26) Java HotSpot (TM) 64-Bit Server VM (build 25.20-b23, mixed mode).

matlab version is:

1.6.0_17-b04 Java with Sun Microsystems Inc. Java HotSpot (TM) 64-Bit Server VM mixed mode

... I changed the version as explained in this link: http://www.mathworks.com/matlabcentral/answers/130359-how-do-i-change-the-java-virtual-machine-jvm-that-matlab-is-using-on-windows.

and now I get the following error in matlab:

>> deploytool
Error using deploytool (line 43)

hi, I solved the problem by installing the compiled java on my computer version, the build process of deploytool worked great. I leave the link here in case anyone is presented with the same problem: http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-javase6-419409.html

Hi Kevin, did you mean you just re-installed the JRE (v1.6u45) from the link you supplied and it worked? I've done this and am still getting an error about XPath.

Thanks Kevin, I had the same problem and used the same solution to solve it. Just need to make sure to erase the environment variable (i'm using Windows 7) that points to Java - called "MATLAB_Java".

Here's the answer received from Mathworks support:

_This is because the customer is using Java 1.8.0_92-b14 rather than Java 1.7.0_60-b19 which is shipped with MATLAB. In order to avoid the Java exception, please use the Java version shipped with MATLAB. Please follow the link given below to change the JVM to Java 1.7.0_60-b19. http://www.mathworks.com/matlabcentral/answers/130359-how-do-i-change-the-java-virtual-machine-jvm-that-matlab-is-using-on-windows_

Customer should be able to run the "deploytool" application by using Java 1.7.0_60-b19.
