Characters "&(." throws exception

[ekn]

hello! I have a struts application running that uses actionForm and nested tags. Whenever a user inputs the characters &quot;&(.&quot; in chronological order on a <nested:textarea>, an exception occurs after submit. I hope somebody can help me solve this.

the error message is as follows:

java.lang.IllegalArgumentException: Invalid mapped property '('

I know very little about jsp and struts. I would use javascript to replace the & by a symbol(or my created word like symbol_and) other than (&, + ,%). After the text is submitted and reach server. When the text is to be displayed, the jsp will change my created word to the real symbol.

use unicode, for &, the equivalent char is &quot;\u0026&quot;. for (, it is &quot;\u0028&quot;. Hence given a string var, x:-

x = &quot;\u0026&quot; + &quot;\u0028&quot; //will give you &(

for the other characters.

oppss. i forgot. so in your bean method, particularly set, you can use a switch statement to check for the input and convert them accordingly.

p/s: someone with refactoring experience might not agree with me using the switch statement So if you use refactoring, you can find the right pattern to apply the idea. good luck

i just wonder why struts cannot handle this? i thought struts does encoding.
