Hi all,

first time using this site. I have a problem. I have a java application i have finished, which I then put into installshield. Now the program has an emailer which uses the MAIL.JAR and ACTIVATION.jar libraries which are not standard with the jre but still from Sun.

I want to copy and paste these libraries into the %JAVAHOME%\lib\ext folder found on the client's pc and need an automated way of doing this since implementation will be on more than one pc.

I have tried to use a batch file but am having a problem between these lines.

::Convert long path (with spaces) into a short path
for %%x in ("%JavaHome%") do set JavaHome=%%~dpsx
echo Java home path (short path, no spaces) = %JavaHome%

before this piece of batch file code is implemented, the location of the java runtime environment is good except for the spaces between 'Program files', etc. After it is implemented it takes off the final folder.

Example:

before batch file code: C:\Program Files\Java\jre1.6.0_03
after batch file code: C:\PROGRA~1\Java\

it leaves out the "jre1.6.0_03"

I know it might be something simple, but as I said, I am new to batch files and have not found anything on the net. :(

Any help will be considered a great help, even without use of batch files completely.

Thanks

Replace

=%%~dpsx

with

=%%~dpsnx

Or, you know, don't worry about about it being a short name or a long name.

Replace %%~dpsx with just %%~sx

This is because %JAVAHOME% expands into a directory path, and the last-level e.g. ("jdk1.6.01_a") is treated by the "for" command as a name, while the prefix is treated as the directory. If you want the full path to the JAVAHOME directory, just get it to give you the full path by specifying just %%~sx.

I wouldn't recommend using %%~dpsnx because, if the last part is, let's say, "jdk1.6", then the ".6" will be treated as an extension and will be stripped off. If you use just %%~sx, it will be kept.

But, as Razor says, why bother? It is quite common to allow spaces in installation scripts. They should be able to handle them.

Also, why are you copying the jar files in the users' JDK directories? What about users who don't have JDKs installed (they won't, if they are not developers) but only have JREs? Perhaps the jars should go where the rest of your application is?
