EL mapEntry.value prints Ljava.lang.String@

[Julien Roubieu]

Hello ranchers,

I've got a problem with printing values from a map to my page.
My code is the following:

<c:forEach items="${myMap}" var="e">
    <input type="hidden" name="${e.key}" value="${e.value}">
</c:forEach>

"myMap" is actually the map returned by request.getParameterMap(), that I put in a request attribute to be printed into this page.
According to API doc this should be a Map<String,String>.

However, what I get in my page is something like :

<input type="hidden" name="p1" value="[Ljava.lang.String;@54acf3">
<input type="hidden" name="p2" value="[Ljava.lang.String;@26bb08">

Why isn't the String value printed ??

Well, as always, we find the answer just after posting the question:
I had misread the API : the request.getParameterMap() method returns a Map<String, String[]>, to handle multiple parameters with the same name.

I just needed to add the array index to get my parameter printed :

<c:forEach items="${myMap}" var="e">
<input type="hidden" name="${e.key}" value="${e.value[0]}">
</c:forEach>

I hope this will help someone else...
