Why am I not able to view the Value of a Sub Flow Chart in the Sub Flow Chart Actions Properties?
You may be experiencing a size issue with your Action Properties pop out menu. You can remedy this by taking your mouse and dragging the left side of the menu to the left. Once you have done this you should be able to view the whole Value of the Sub Flow Chart Property.

Why am I seeing 'Jar: '-u' mode unimplemented'?
Flux does not support GCJ. If you try to run Flux against GCJ, you will encounter errors.

If you are running GCJ, we suggest installing Java 1.5 or 1.4 from the Sun site at: java.sun.com.

If you continue to experience problems with Flux after you have installed Java 1.5 or 1.4, you may need to check your global variables for JAVA_HOME and PATH as there may still be a reference to the GCJ version of Java instead of the Sun version of Java.

To find out if GCJ is conflicting with another version of Java, run these commands in a shell:

echo $JAVA_HOME
echo $PATH

If GCJ shows up in JAVA_HOME, it should be replaced with the path of your Java 1.5 or 1.4 install. If GCJ shows up in the PATH variable, make sure that the location of Java 1.5 or 1.4 is before the location of GCJ.

How do I embed my Flux license key?
This depends on what version of Flux you are running. For both instances you will want to place your Flux license key into your Flux installation directory. If you are running Flux 7.0 or higher, run the configuration script to embed the license key. However, if you are running Flux 6.5 or older, you will need to run the following command in your Flux installation directory:
```
jar -uvf flux.jar fluxkey-X-X.txt (i.e. jar -uvf flux.jar fluxkey-6-5.txt)
```

How do I find the correct machine information to send you when wanting to add a machine to my Flux license?
If you want to add a machine to your Flux license, you will need to run the following command in your Flux installation directory and send us the output:
```
java -jar flux.jar
```

When I try to start a Flux engine I receive the repeated error "magic number 56 is not available in magic map." How do I fix this?
This behavior can be corrected by setting the following configuration options for the engine:
```
cluster_networking=false
clust_enabled=false
```

Why do I receive the "HTTP: ERROR 500 unable to compile class for JSP" error?
This error often indicates that the full Java JDK was not installed. Check to make sure you are using a Java JDK and not a JRE. Also, check your JAVA_HOME environment variable to make sure it is not pointing at the wrong Java installation.
