I'm using struts2-jquery grid.

gridmodel in my action class is getting updated correctly. But, nothing is getting displayed on the grid.

struts.xml



userList.jsp



ListUsers.java



I did refer to the solution on http://stackoverflow.com/questions/6411589/struts2-jquery-grid-data-not-load?answertab=active#tab-top

But that solution did not work. Instead of data getting displayed on the grid, it prompted to save the file & that file contained the following info:

{"JSON":"success","gridModel":[{"email":"user1@email.com","fullName":"User ABC","id":1,"userName":"user1"},{"email":"user2@email.com","fullName":"User DEF","id":1,"userName":"user2"}],"page":0,"record":2,"rows":0,"sidx":null,"sord":null,"total":2147483647}

As per my understanding row & page are automatically handled by the plugin. But as per the json data above they are not getting incremented. Hard-coded them to the size of the gridmodel and the json data I got is:

{"JSON":"success","allApplicationData":"success","gridModel":[{"email":"user1@email.com","fullName":"User ABC","id":1,"userName":"user1"},{"email":"user2@email.com","fullName":"User DEF","id":1,"userName":"user2"}],"page":1,"record":2,"rows":2,"sidx":null,"sord":null,"total":1}

Hi,
Your solution worked. But got a better way around.

While declaring the iterator :


Try . It worked.

Hi,

I'm using <sj:datepicker> tag as follows :



My pom.xml declares the related dependency as:


But, the calender/date picker is not getting displayed. Instead it is being displayed as a textfield on the browser.

What could be the issue?

Hi,

When I run my web application (struts2) , the index page is displayed correctly. When I click the button on the index page, the following error occurs:

HTTP Status 500 -

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

I'm not able to understand the reason. I'm new to web app development, please help..

Change the last executable line of startup bat to use "run" instead of "start" - this will execute the catalina.bat in the same window so you can see the error.

Hi Bill,

Thanks

I changed the exectable's last statement.

Got the following information:

Hi,


I'm using Windows 7 64 bit machine & having Java 1.6.

I am not able to start tomcat. I just downloaded the tomcat, unzipped the file & set the environment variables.

When I run startup.bat from command prompt, it shows the following on my command prompt:


C:\apache-tomcat-7.0.23\bin>startup.bat
Using CATALINA_BASE: "C:\apache-tomcat-7.0.23\"
Using CATALINA_HOME: "C:\apache-tomcat-7.0.23\"
Using CATALINA_TMPDIR: "C:\apache-tomcat-7.0.23\\temp"
Using JRE_HOME: "C:\Program Files\Java\jdk1.6.0_25\"
Using CLASSPATH: "C:\apache-tomcat-7.0.23\\bin\bootstrap.jar;C:\apache-tom
cat-7.0.23\\bin\tomcat-juli.jar"

The Tomcat window opens for a few milliseconds n get closed. No information is being logged.

Please guide me. I am not able to figure out whats missing. Let me know if any other information is required.
