Hi Dave,

I am using the commons-configuration for my property files. However, unfortunately, I have a need to have a value in some of my properties that look exactly like the variables that commons-config uses.


I've tried to escape it thus:


but all to no avail.

Is there any way for me to get around this conflict? Can I change the delimiter that commons-config uses (I've looked at all the classes, there doesn't seem to be a way)?

The error I'm getting is this:

java.lang.IllegalStateException: infinite loop in property interpolation of ${DB2UNIVERSAL_JDBC_DRIVER_PATH}/db2jcc.jar,${DB2UNIVERSAL_JDBC_DRIVER_PATH}/db2jcc_license_cu.jar,${DB2UNIVERSAL_JDBC_DRIVER_PATH}/db2jcc_license_cisuz.jar: DB2UNIVERSAL_JDBC_DRIVER_PATH->DB2UNIVERSAL_JDBC_DRIVER_PATH

which version of Commons Configuration do you use? Since the 1.3 release substituation of variables is handled by the StrSubstitutor class of Commons Lang [1]. Here the '$' sign is used for escaping variables, so your 3rd example


should work. There is also a unit test that checks this behavior:

    public void testInterpolationEscaped()
        config.addProperty("var", "x");
        config.addProperty("escVar", "Use the variable $${${var}}.");
assertEquals("Wrong escaped variable", "Use the variable ${x}.", config

IIRC in earlier versions of Configuration escaping variables was not supported.
