rules making recursive redirect

[Facundo Curti]

Hi there. I'm trying to make work this rules, but for some reason, it trigers a recursive redirect.

<!-- Para direcciones del estilo /algo (sin nada más despues)-->

    <rule>

        <from>/([a-z]+)$</from>

        <to>/motor/index.jsp?empresa=$1</to>

    </rule>

    

    <!-- Para direcciones del estilo /algo/ (sin nada más despues)-->

    <rule>

        <from>/([a-z]+)/$</from>

        <to>/motor/index.jsp?empresa=$1</to>

    </rule>

    

    <rule>

        <form>/iniciar-sesion$</form>

        <to>/motor/login.jsp</to>

    </rule>

I get:

org.tuckey.web.filters.urlrewrite.NormalRewrittenUrl.doRewrite(NormalRewrittenUrl.java:213)
	org.tuckey.web.filters.urlrewrite.RuleChain.handleRewrite(RuleChain.java:171)
	org.tuckey.web.filters.urlrewrite.RuleChain.doRules(RuleChain.java:145)
	org.tuckey.web.filters.urlrewrite.UrlRewriter.processRequest(UrlRewriter.java:92)
	org.tuckey.web.filters.urlrewrite.UrlRewriteFilter.doFilter(UrlRewriteFilter.java:394)
	org.tuckey.web.filters.urlrewrite.NormalRewrittenUrl.doRewrite(NormalRewrittenUrl.java:213)
	org.tuckey.web.filters.urlrewrite.RuleChain.handleRewrite(RuleChain.java:171)
	org.tuckey.web.filters.urlrewrite.RuleChain.doRules(RuleChain.java:145)
	org.tuckey.web.filters.urlrewrite.UrlRewriter.processRequest(UrlRewriter.java:92)

	org.tuckey.web.filters.urlrewrite.RuleChain.handleRewrite(RuleChain.java:171)
        ....
        ....

Do you have some idea why is this? What i'm doing wrong? :S
