[rajyalakshmi.suman]

Hi,

After button click page gets refreshed & value is not persisting in textfiled
Have tried using form:tags ,spring:bind tags ...
If am using "Spring :bind ":value is persisting but results are not getting displayed after onclick :button .

Kindly let me know is it possible in spring+portletjsr168 ?

String strFname=null;

When posting code please use the [ code][/code ] tags, that way we can read your code...

I don't understand why you are creating all that stuff in your JSP, your controller should handle that. I suggest you read the reference guide and checkout the samples (especially the SpringMVC part) because yu seem to be missing the basics.


public class YourController extends SimpleFormController {

protected Object formBackingObejct(HttpServletRequest request) {
return new BDCompanyFilterCommand();
}


}

<td class="wpsTableText">Company name</td>
<td class="wpsTableText">Business unit Nr.</td>
<td class="wpsTableText">Active</td>

<tr>
<td>&nbsp;&nbsp;<form:input cssClass="wpsEditField" path="firmename" size="15" maxlength="10" /></td>
<td>&nbsp;&nbsp;<form:input cssClass="wpsEditField" path="bu_nr" size="15" maxlength="10" onkeypress="return checkNumberic(event);" /></td>
<td>&nbsp;&nbsp;<input type="checkbox" name="chkActive" onclick="populateActive()" /></td>
<form:hidden path="active" />
</tr>
<tr>
<td colspan="2">&nbsp;<button type="submit" class="wpsButtonText" onclick="populateActive()">Search</button></td>
</tr>
</table></fieldset>
</form:form>

Also your jsp with all that javascript looks overly complex, especially the part where you are checking active/chkActive, seems redundant to me.
