JSF? accessing String array elements in JSF/JSP/Managed Bean
In struts you can do the following:
In the bean
private String strAry[] = { "FAM_1.JPG", "FAM_2.JPG", "FAM_2.JPG" };
public String getStringIndexed(int index) {
return strAry[index];
}
public void setStringIndexed(int index, String value) {
strAry[index] = value;
}
}
In the jsp:
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<jsp:useBean id="bean" class="org.apache.struts.webapp.exercise.StringBean"/>
<bean:write name="bean" property="stringIndexed[1]"/>
I've tried to do the same thing in JSF without success.
How can I access something similar to this
<h:graphicImage value="#{ThumbBean.stringIndexed[0]}" alt="No Image"/>
Since JSF 1.2/EL 2.1/JSP 2.1 :
If your stringIndexed is an array type property of the ThumbBean, you can access its element
from EL provided that you have:
public String getStringIndexd(int index){
return stringIndexed[index];
}
in your bean class code.

Thanks for your response. I had that piece of code in my bean. My question was more how I access it from the jsp.
<h:graphicImage value="#{ThumbBean.stringIndexed[0]}" alt="No Image"/>
The line above was not working. The exception was that this was not a property of the bean.
I dunno about arrays but I know you can use similar expressions with Maps:private Map<String, String> map;
public Map<String, String> getData() {
return map;
}
value="#{bean.map['key']}"

Read my first reply and use a JSF 1.2/EL 2.1/JSP 2.1 implementation.
Array indexing for bean property from JSF EL works just fine on them.
