Exit status running java classpath in a unix shell script

[mmcds]

I have a java classpath running inside of a unix shell script. During my testing it will error with java.io.FileNotFoundException error, which I know why that is, but when I set in my unix shell script this to see the right exit status of success/fail, it always shows a 0 for success when that isn't really the case. Below is the two lines I have set to capture the exit status and just display that exit status for now.

notifycode=$?
echo $notifycode

I have these 2 lines above on a line right below my java command in my unix shell script. How can I get my unix shell script to show the right exit status if the java classpath command fails? Thanks for any help.

but do you know that it has a non zero (should be 2 for File Not Found) exit status?.

No I am not sure of what the exit status of that error is. How can I find out exactly?

Also, after that error example I gave, there are plenty of lines that don't show any errors, for example like the lines below.

at java.io.FileInputStream.open(Native Method)
at java.io.FileInputStream.<init>(FileInputStream.java:129)

So I am wondering if since my error happens before lines like the example above, the exit status gets overridden with the most recent exit status of the last command?

Almost certainly



When testing I assume that you run the command from the command prompt. To check the return try

echo $?

I ran the echo $? and sure enough it shows 0 for the exit status. Is there any way to capture the error exit status that could occur anytime during processing like for my FileNotFound Exception error? That is what I am trying to accomplish.

I don't know enough java but something like

ERROR_STORE=0
java.command.1 || ERROR_STORE=$?
java.command.2 || ERROR_STORE=$?
java.command.3 || ERROR_STORE=$?
java.command.4 || ERROR_STORE=$?
echo $ERROR_STORE

may be posible
