Convert a substring to integer

[Uwe <st...@ebers.de>]

Hello Community,

I'm quite new to Struts2 (or even Struts anyhow) and I'm struggling with 
a Problem .

My multiline Form send's via  the validation the fieldError data as 
shown below to my jsp. Because I do have a multiline form my return of 
the Object key is something like:
myrecords[3].myfieldName. This information is not the best for my Users 
so I want to break it up in something like : At row 4 (because it starts 
counting 0) in Column MyFieldName is Error blablabla... Therefor I need 
to extract the index and the Fieldname. Well the problem is the index. 
As you can see in my example below I have extracted the index (in my 
example 3 ) from the Object key. And that works pretty fine. But, and 
now comes my Problem, it's still a String and I can't add the int 1 to 
it. I have tried several things in different combinations but nothing 
worked out.

<s:iterator value="fieldErrors" >
	<s:set name="r2" value="%{key.substring(key.indexOf('[')+1,key.indexOf(']'))}"/>
	<s:set name="r3" value="%{#r2.trim()}"/>  //howto convert r3 to a integer?
	<s:property value="r3"/><br>
</s:iterator>

Thanks for any help

Uwe

I'm not sure that is a good solution but u can try to use simply jsp code
and bean:define

e.g (i don't know the right name of the struts tag)

<bean:define name="myvar>
<%=all the operation%>
</bean:define>

<s:set name="r2" value="${myvar}"/>

i don't really know it's works, but it'll be, i'm not so sure.

otherwise:
u want to display the error in the right place?
why u don't use a different error name for each fields?

(i don't remember well how to do this, but i guess that is possible, i'd
done in past).

bye
