# How to set multiple paths in the CLASSPATH using the --classpath option for "gfsh start server" on Windows

Environment

 Product Version Pivotal GemFire tested on 8.2.1.1 OS Windows platform

## Purpose

This article explains how to include multiple paths in the CLASSPATH using the --classpath option to the gfsh start server command on Windows when using gfsh in interactive mode.

## Cause

Suppose that you execute the gfsh start server command intending to include multiple paths to the CLASSPATH using the --classpath option as in the following:

gfsh> start server --name=cache1 ...(snip)... --classpath=C:\path\to\lib1.jar;C:\path\to\lib2.jar

Although this will start the server, only first path is set in the CLASSPATH (in this case, only the path to lib1.jar) and gfsh will give the following message:

Command "C:\path\to\lib2.jar" is not valid.

On Windows systems, the semicolon (;) is used as a delimiter sign for java class paths. The issue is that it is also recognized as a delimiter sign for gfsh commands. Hence, gfsh reads the semicolon in the CLASSPATH as a terminator for the start server command and anything following as a new command.

## Procedure

In order to include multiple paths using the --classpath option in gfsh on a Windows system, you will need to escape any semicolons with a backslash (\) as in the following example:

gfsh> start server --name=cache1 ...(snip)... --classpath=C:\path\to\lib1.jar\;C:\path\to\lib2.jar
