OCPsoft Rewrite Rule no longer works after Update from 1.0.5 to 1.1.0

When updating OCPsoft Rewrite from Version 1.0.5.Final to 1.1.0.Final the following Rule no longer works and I don't know how to fix it:

.addRule(
    Join.path("/{i}/{d}")
        .where("i").matches("[-_a-zA-Z0-9~*]{8}")
        .where("d").matches("[-_a-zA-Z0-9~*]{32}")
        .to("/resources/html/user/doSomething.html?i={i}&d={d}")
)

In the Rewrite changelog there is one point that could help you help me:

Configuration strings are now literal. Regular expressions must be configured through a >parameter such as: .defineRule().when(Path.matches("/{*}").where("*").matches(".*"))

The exception I get is the following one:

Exception starting filter OCPsoft Rewrite Filter
    java.lang.NullPointerException
        at org.ocpsoft.rewrite.servlet.config.rule.Join.where(Join.java:199)

        ...
Solution

  • The following did the trick, I just had to reorder the join clauses:

    .addRule(
    Join.path("/{i}/{d}")
        .to("/resources/html/user/doSomething.html")
        .where("i").matches("[-_a-zA-Z0-9~*]{8}")
        .where("d").matches("[-_a-zA-Z0-9~*]{32}")
        .withRequestBinding();
)

    Thanks to Lincoln, who figured this out and answered my question on the Rewrite support forums.
