gwt tomcat unix doesn't work

[fedex]

Hi everyone

I am using tomcat version 6 in the unix server. When I try to run the sh 
version.sh file I get an error saying bad version. bin/bootstrap is not 
working i believe. I checked the jdk and jre version . They are compatible 
. I used commands java -version and javac -version to check the 
compatibility of java and compiler version. 

Recently I developed an application using GWT framework. When I deploy the 
application on the local tomcat server it wrks greats in the windows. I am 
using jdk 1.7 and jre7 in my local and verified on both tomcat version 6 & 
7. The application worked great and have no issues. I used ANT script to 
package the application so to deploy on unix server. I used the same ANT 
script to build the package when I deployed on local tomcat. 

Can anyone suggest what exactly could have gone wrong. Based on the error I 
understand compiler is not compatible to java version. When I run the sh 
version.sh in unix it showed the JRE HOME variable as /usr folder. I found 
in that folder java and jre compatible. Please help . Thanks

gwt compilation issue

[fedex]

For my current Gwt project when I compile the project it creates  web-inf 
folder outside the war folder. 

Initially While working on project I accidentally deleted war folder and I 
kind of setup the folder manually by copying the files from my backup 
folder. I am not sure if this is the reason for it..if yes what I am 
suppose to do.

static methods question

[fedex]

Static methods executes at compile time then it executes before the object 
construction (as they get constructed during run time). But in our main 
method we create a class object and invoke class methods right . How does 
this happen when the method execution is happening at compile time it 
should throw an exception for object construction. Can you explain

public class animal {

public void behaviour() {
System.out.println("I am a dog");
}

}

public class Tiger {
public static void main(String[] args) { 
Animal ani = new Animal();  // here we are construction animal object which 
gets created runtime. How come static method gets executed then?   
  ani.behaviour(); 
  
 }
}

sorry this is not related to GWt

suggest box with rpc call - question

[fedex]

Hi everyone,

I am placing an suggestbox on the front interface whhere upon typing any 
value or letter corresponding list matching to that letter needs to appear. 
I am using keydownhandler event to obtain this.As you can see the below 
code I am making an RPC call to obtain the list of data from the oracle 
database . Suppose user has typed in letter 'D' the following query runs 
"String sql = "select NAME from DOM_REFERENCE_TABLE where DESCRIPTION = 
'NationalAccountDetails' AND NAME LIKE upper ('" + tablename +"%') ORDER BY 
NAME ASC";

where tablename value is 'D' so it pulls all the values from database 
starting with letter 'D'. This list will be added to the oracle object as 
shown in the response of RPC call. So, my problem is the list that needs to 
appear when user types in letter'D' doesn't happen for the first time but 
happens when user types in 'Next time'. I guess you people understood what 
I am trying to say. As the list gets added to oracle with keydown event it 
is not showing at that time but it will show for next event. But I need the 
matching list to be shwon in the same event. How can I achieve this? 


private MultiWordSuggestOracle oracle = new MultiWordSuggestOracle();
private SuggestBox suggestBox = new SuggestBox(oracle);

Key down event:
suggestBox.addKeyDownHandler(new KeyDownHandler(){
public void onKeyDown(KeyDownEvent event) {
// TODO Auto-generated method stub
String tablename = suggestBox.getValue();
if (tablename != null && !tablename.isEmpty()) {
datamartClientImpl.retrieveNATLData(tablename);
}
}

});

Response from RPC call
public void updateSuggestBox(DomesticDMAHistBean domesticDMAHistBean) {
oracle.addAll(domesticDMAHistBean.getNatldesc()); // obtaining the list 
with startin letter 'D'
hPanel.remove(Metrics);
hPanel.remove(bttnDomesticNATLHist);
vPanel.clear();
vPanel.add(suggestBox);
hPanel.add(vPanel);
hPanel.add(Metrics);
hPanel.add(bttnDomesticNATLHist);
}

SuggestBox with keydownhandler event - Question

[fedex]

Hi everyone,

For my application, I am adding a suggestbox on the front interface so when 
user types in any letter corresponding list (we won't add the list to the 
interface. It will be shown as the user types in and changes 
correspondingly when the letters changes as we generally see in online 
websites) matching to that letter needs to appear on the front interface. I 
am using keydownhandler event to obtain this.As you can see the below code, 
I am making an RPC call to obtain the list of data from the oracle database 
. Suppose user has typed in letter 'D' the following query runs 
"String sql = "select NAME from DOM_REFERENCE_TABLE where DESCRIPTION = 
'NationalAccountDetails' AND NAME LIKE upper ('" + tablename +"%') ORDER BY 
NAME ASC";

where tablename value is 'D', so it gets all  values starting with letter 
'D' from database. This list will then be added to the oracle 
(MultiWordSuggestOracle) object as shown in the below code(see at Response 
of RPC call Tag). So, the problem is the list that needs to appear when 
user types in letter'D' doesn't happen for the first time but happens when 
user types in Next time. I guess you people understood what I am trying to 
say. As the list gets added to oracle with keydown event it is not showing 
at that time but it will show for next event. But I need the matching list 
to be shown in the same event. How can I achieve this? Any suggestions? Let 
me know I need to clarify more on this. Thanks in advance

Code:


// Object Declaration
private MultiWordSuggestOracle oracle = new MultiWordSuggestOracle();
private SuggestBox suggestBox = new SuggestBox(oracle);

// Key down event:
suggestBox.addKeyDownHandler(new KeyDownHandler(){
public void onKeyDown(KeyDownEvent event) {
// TODO Auto-generated method stub
String tablename = suggestBox.getValue();
if (tablename != null && !tablename.isEmpty()) {
datamartClientImpl.retrieveNATLData(tablename);
}
}

});

// Response from RPC call
public void updateSuggestBox(DomesticDMAHistBean domesticDMAHistBean) {
oracle.addAll(domesticDMAHistBean.getNatldesc()); // obtaining the list 
with startin letter 'D'
hPanel.remove(Metrics);
hPanel.remove(bttnDomesticNATLHist);
vPanel.clear();
vPanel.add(suggestBox);
hPanel.add(vPanel);
hPanel.add(Metrics);
hPanel.add(bttnDomesticNATLHist);
}

doesn't allow to create a keydownhandler for the suggest box

[fedex]

Hi,

I am trying to create a keydownhandler event for the suggest box but it 
won't allow me to do so? why

It shows this error
" The method addKeyDownHandler(KeyDownHandler) in the type SuggestBox is 
not applicable for the arguments (new KeyDownHandler(){})"


Here is my code:

private MultiWordSuggestOracle oracle = new MultiWordSuggestOracle();
private SuggestBox suggestBox = new SuggestBox(oracle);
suggestBox.addKeyDownHandler(new KeyDownHandler(){

@Override
public void onKeyDown(KeyDownEvent event) {
// TODO Auto-generated method stub

need to send any value from server to client to stop the display page loading

[fedex]

i,

In my current application I am writing a huge data to write the csv file. 
For passing the values from client to server I used GWT-RPC call to send 
the data to server. Now, I need to send some value from server to client 
once the query is executed to stop the display page loading. How can I 
achieve this? is there any way where we can send the data from server to 
client

it won't accept http portals. How can I change the dev mode URL to https? 
if else is there anyway i can overcome this issue. And one more thing is my

only RPC call completes rest of my code should execute - how should I do it - very urgent please

[fedex]

Hi everyone,

I have an interface where the user selects the values and upon clicking the 
download button the selected values runs in the sql query and the obtained 
data is written to csv file. 

I am doing an RPC call to send the user selected values from the interface 
to the server. And on the server side I am storing these values in the http 
session variable. And I am retrieving these values in the servlet class 
which has a funtionality to write a data to csv file. Because the values 
send to the server is a RPC call, my initial session value remains zero ( 
first download click) and it writes nothing to the csv file though i have 
selected values from the user. On second click of download button it writes 
the data of the first selected values. How can expedite the RPC call or how 
can I make a RPC to synchronize call ? Can someone please suggest a 
possible to overcome this? Thanks a lot in advance

I am storing the values in the session by making an rpc call. So, to get

rpc call - static methods is not working

[fedex]

Hi everyone,

I am trying to define a static method in the service interface to make an 
rpc call. But it doesn't allow me to do so. here I am pasting my code

Client class 

public void sendDomesticData(String product,String dma,String 
yrmnths,String dist,String metrics) { 
String url = GWT.getModuleBaseURL() + "domesticservice";
domesticServiceAsync = (DomesticServiceAsync) GWT
.create(DomesticService.class);
ServiceDefTarget endpoint = (ServiceDefTarget) domesticServiceAsync;
endpoint.setServiceEntryPoint(url);
domesticServiceAsync.sendDomesticData(product,dma,yrmnths,dist,metrics,new 
Domestichandler() );
}

public class Domestichandler implements AsyncCallback {

@Override
public void onFailure(Throwable caught) {
String error = caught.getMessage();
System.out.println(error);
 }

public void onSuccess(Void result) {
System.out.println("perfect");
 }
 }

Service 
public interface DomesticService extends RemoteService {
 public  void sendDomesticData(String product,String dma,String 
yrmnths,String dist,String metrics);

}

public interface DomesticServiceAsync {
 void sendDomesticData(String product,String dma,String yrmnths,String 
dist,String metrics,AsyncCallback callback);
}

server side -

public  void sendDomesticData(String product, String dma,
String yrmnths, String dist, String metrics) { 
System.out.println(product); 
}

Basically I am trying to send the values from the front interface to the 
 server side and I don't want any return value. But the values passed to 
the server side should be stored globally in the server class so i can 
access those values in different method. I tried changing all the 
senddomestic values to static but it won't allow me to do so? why?

Re: how to send huge list of data to the server side from client interface in GWT

[fedex]

I don't want to use RPC call because since I have to just send the list to 
server and don't need any response back. is it possible using RPC?

how to send huge list of data to the server side from client interface in GWT

[fedex]

Hi everyone,


In my current application I have to send huge list of data to the server 
side which will be passed to the oracle query. Currently I am using 
window.Location.replace(quertstring) method to pass the list where  by 
using request parameters we can obtain the client interface values. But it 
seems to be an issue since it doesn't allow ampersand values to pass & even 
If the list is huge the socket connection ends. Is there a way i can 
overcome these issues? Any  framework in GWT can help me resolving this?

date in the csv file doesn't update unless I stop the application and restart it

[fedex]

Hi everyone,

I am writing a huge data list to the csv file. When I start the application 
and click on download the csv file open with the time and date. If i select 
different options on my interface and click download without closing the 
server (jetty -inbuilt for GWT) the time still shows the same. It won't get 
update. But the data written gets update  based on my selection from 
interface When i close the application and restart it then the time gets 
update. why is it so? is it because of cookies?
