Passing Multiple Parameters into Action class
Hi everyone, I have a problem passing in multiple parameters into my action class for processing.
<html:formaction="/AddUriPolicy.do" method="GET">
<table border="1">
<tr>
<td>Policy Name</td>
<td><html:text property="polyname"/></td>
</tr>
<tr>
<td>UriSet Name</td>
<td>Rate</td>
<td>Type</td>
<td>QueryAuth</td>
<td>Usage</td>
</tr>
<logic:present name="ratelist">
<logic:iterate name="ratelist">
<tr>
<td><bean:write name="ratelist"/></td>
<td><html:text property="polyrate"/></td>
<td>
<html:select property="polyratetype">
<html:option value="browse">browse</html:option>
<html:option value="event">event</html:option>
<html:option value="time">time</html:option>
</html:select>
</td>
<td>
<html:select property="polyrateauth">
<html:option value="Enable">Enable</html:option>
<html:option value="Disable">Disable</html:option>
</html:select>
</td>
<td>
<html:checkbox property="polyratechecked">
</html:checkbox>
</td>
</tr>
</logic:iterate>
</logic:present>
</table>
<input type="submit" name="Submit" value="Add More">
<input type="reset" name="Reset" value="Reset">
</html:form>
The problem I have is that I need to pair the user's input by row. How can I pass the parameters from my jsp page so when in my Action class, I can request.getParameterValues and get the 5 values of each row separately?
I also populate one of the columns from
<logic:iterate name="ratelist">
<td><bean:write name="ratelist"/></td>
Rather than printing the text out, how can I autofill a textbox with this value?
I would appreciate any suggestions, thanks!

If you're using struts, you should take advantage of the framework, and let it do all the hard work.
What you want to use are struts indexed properties.
http://struts.apache.org/1.2.9/faqs/indexedprops.html
What you probably want is a nested indexed property.
Create a bean to store ONE record - ie with name, rate, type etc
On your formbean have an array/collection of these (array is probably easier)
// Bean
public class URIPolicy{
String name;
String polyrate;
String polyratetype;
String polyrateauth;
// plus getters/setters
}
// formbean
public class URIPolicyForm extends ActionForm{
URIPolicy[] ratelist;
public URIPolicy getRatelist(int i){
return ratelist[i];
}
public void setRatelist(int i, URIPolicy policy){
ratelist[i] = policy;
}
And then in your JSP, use it as an nested indexed attribute
Where previously you had <html:text property="polyrate"/>
You now need
<html:text name="ratelist" property="polyrate" indexed="true"/>
This should autoname/number the fields something like
<input type="text" name="ratelist.polyrate">, and will automagically populate into the action form.
<html:formaction="/AddUriPolicy.do">
<logic:present name="ratelist">
<logic:iterate name="ratelist">
<tr>
<td><bean:write name="ratelist"/></td>
<td><html:text name="ratelist" property="polyrate" indexed="true"/></td>
<td>
<html:select name="ratelist" property="polyratetype" indexed="true">
<html:option value="browse">browse</html:option>
<html:option value="event">event</html:option>
<html:option value="time">time</html:option>
</html:select>
</td>
<td>
<html:select name="ratelist" property="polyrateauth" indexed="true">
<html:option value="Enable">Enable</html:option>
<html:option value="Disable">Disable</html:option>
</html:select>
</td>
<td>
<html:checkbox name="ratelist" property="polyratechecked" indexed="true">
</html:checkbox>
</td>
</tr>
</logic:iterate>
disclaimer: none of the above code is tested at all, but it should give you the idea. Post back if you have troubles.
