How to retrieve hashmap Values in other class within the same package.

I have created two class ie A and B.
In A class I have created one hashmap and stored some keys and values.
But i want to retrieve that values in class B.
So can any one can give any code ,so that i will try on Eclipse IDE

Maybe anything. I'm not that interested. It's Java programming 101, about 10 minutes into the first class.

HELP: signer info doesn't match info of other classes in the same package

I have several jars which need to be signed. They contain several applications and packages which
are split up based on which parts are needed by server vs client code. How do I get rid of this error?
I'm signing all the jars using the keytool and jar signer in java 1.3.1. I generate a certificate file.
My assumption is that each time I sign a different jar, the info is updated in the keystore and
certificate file. What might I be doing wrong when signing multiple jars?
(Yes, code from the same package may be in different jars. I don't have any controll of this,
I'm not in charge of the build and distribution of the various packages).

Accessing other classes in the same package

I have the following two classes in the same package. Why cant I access the myString vairable from Test2 like I try and do below?
package test;
class Test1 {
     public static String myString = "Hello world";
package test;
class Test2 {
     static void printMe(){
          System.out.println(Test1.myString);
     public static void main(String args[]) {
               printMe();
}

Why when I take the "package test;" line of code away I can compile it normally?This depends on how you call the compiler and how you have set the class search path. Classes that are in a package are expected to be found from some place in the search path under a directory that has the same name as the package. The default class path consists of only the current directory, ".", so you can avoid all problems by compiling and running from the directory above "test" rather than "test" itself.

Signing 2 different classes in the same package differently.

I have a class B in the default package.
I have another class C which is kept in a jar file without any package information. I have signed this jar file in using one alias in my keystore.
class B instantiates class C and passes its own reference to it.
When I run class B, i get an error saying,
Exception in thread "main" java.lang.SecurityException: class "C"'s signer information does not match signer information of other classes in the same package

Does this mean, I cannot have 2 classes in the same package, signed differently?

Can i use one JSF component's value for other component in the same page.

Can i use one JSF component's value for other component in the same page.
For example
I have a <h:selectBooleanCheckbox id="myChk"> in my jsf page, i want to access its value for another component like:
<h:commandButton disabled="#{myChk.checked}" action="myAction" value="myValue" />
** "myChk.checked" >> I am just asuming "checked" property is available...

Bind the checkbox to a UIInput myChk property. Then you can reference this property from the page, e.g.
<h:selectBooleanCheckbox binding="#{myBean.myChk}" onchange="submit();" />
<h:commandButton disabled="#{myBean.myChk.value}" action="myAction" value="myValue" />

Cannot acess classes in the same package.

Hi
I have "a.java" in c:/java/test directory. I have "b.java" file in the same directoty which creates a instance of "a" class. "a.java" compiled fine. But when compliling "b.java" i get error message
cannot resolve symbol
symbol : class a
I have used "public" as acess modifier for both the classes. As per rule I can access the classes in the same package. But for some reason my program is not compiling. Can anyone tell me what the acutal problem is.
Thanks in advance.

Javapedia: Classpath

How to make use of adjacent data elements within the same buffer

Hi,
         Does anyone know how to make use of adjacent data elements within the same buffer? To make my question clearly, I would like to give you an example. In my application, I set "sample to read" as 10 which means at each loop 10 data samples will be taken into a buffer. Now, what I would like to do is to do some calculations on adjacent data samples in same buffer. I tried to use "shift register" for this, but it seemed to me that it only can deal with the calculation between data from adjacent loops. In other words, it skips 9 data elements and take the 10th one for the calculation.
         Here I also attach my VI showing what I did.
    Thank you very much in advance,
                        Suksun

Hi Suksun,
      I hope you'll forgive me for distilling your code - mainly to understand it better. I tried to duplicate your logic exactly - which required reversing the "derivatives"-array before concatination with the current samples array. As in your code, the last velocity is being paired with the first position. If first velocity is really supposed to be paired with first position, just remove the "Reverse 1D Array" node.
cheers

How do I sink calendars with other users on the same computer

How do I sink calender info with other users on the same computer?

Hi there,
First..I am new to this forum and find the information provided to be very helpful... I had followed the iTunes link above to enable sharing between users in the same computer but it appears to be working on partially. What setup am I looking for ?
1. We have an iMac (Snow Leopard) with 1 Adult ID and 2 children IDs
2. The iTunes music folder is stored in a Shared public folder where the Adult ID has read/write access and the 2 kids with read-only access (so that they don't accidently delete songs...:-)
3. The iTunes on the Adult ID has the access to purchase songs. The kids have no acccess to buy songs
4. All songs, podcasts to be visible to all users
What has happened ?
1. I am able to make the base of songs visible to all users
2. However when a song is purchased by the adult account ..it is not visible to the kids account ..:-{
3. The same thing occurs when a song is imported from a CD
4. When a new playlist is created by the Adult account it is not visible to the kids account ..:-(
How can I make changes made by the Adult be made visible to the kids without having the need to constant add music files or libraries for each kid..?
Thanks in advance..

How does the automatic compilation occur for 2 classes in the same package?

Hi friends,
This is my first file Base.java
package Base;
class Base {
protected void amethod() {
System.out.println("amethod");
}This is my second file :
package Class1;
public class Class1 extends Base {
public static void main(String argv[]) {
Base b = new Base();
b.amethod();
}However even if I compile only Class1,why do I get the output as "amethod" ? I an not compiling Base class also with this.Do the files get automatically compiled if they are in the same package ?
Thanks.

How do I open something from other program in the same/ current tab? IE has this functionality under internet options

How can I get applications to open in the same tab/window I am working in. In IE it was very simple. Its just a check-box under internet options. I cannot figure it out with Firefox yet
== This happened ==
Every time Firefox opened
== i started using it

I'm not sure but maybe the Tab Mix Plus extension provides that option https://addons.mozilla.org/en-US/firefox/addon/1122/

How do I import music from other libraries on the same computer?

We have four separate accounts created on our iMac for four different users. Each of these accounts has an iTunes library associated with it. I would like to be able to import music from one iTunes library to another. I would be grateful for any help!

To give other users read-only access to your iTunes library, use the Sharing features of iTunes. Sharing works over the local network as well as on the same computer. See the built-in help for details.
If you want to give full read/write access to more than one user, see the support article linked below.
iTunes: How to share music between different accounts on a single computer
There is a way to share the library without moving it to a secondary volume. If you really need to do that, ask for instructions.

Passing a parameter from one class to another class in the same package

Hi.
I am trying to pass a parameter from one class to another class with in a package.And i am Getting the variable as null every time.In the code there is two classes.
i. BugWatcherAction.java
ii.BugWatcherRefreshAction.Java.
We have implemented caching in the front-end level.But according to the business logic we need to clear the cache and again have to access the database after some actions are happened.There are another class file called BugwatcherPortletContent.java.
So, we are dealing with three java files.The database interaction is taken care by the portletContent.java file.Below I am giving the code for the perticular function in the bugwatcherPortletContent.java:
==============================================================
public Object loadContent() throws Exception {
Hashtable htStore = new Hashtable();
JetspeedRunData rundata = this.getInputData();
String pId = this.getPorletId();
PortalLogger.logDebug(" in the portlet content: "+pId);
pId1=pId;//done by sraha
htStore.put("PortletId", pId);
htStore.put("BW_HOME_URL",CommonUtil.getMessage("BW.Home.Url"));
htStore.put("BW_BUGVIEW_URL",CommonUtil.getMessage("BW.BugView.Url"));
HttpServletRequest request = rundata.getRequest();
PortalLogger.logDebug(
"BugWatcherPortletContent:: build normal context");
HttpSession session = null;
int bugProfileId = 0;
Hashtable bugProfiles = null;
Hashtable bugData = null;
boolean fetchProfiles = false;
try {
session = request.getSession(true);
// Attempting to get the profiles from the session.
//If the profiles are not present in the session, then they would have to be
// obtained from the database.
bugProfiles = (Hashtable) session.getAttribute("Profiles");
//Getting the selected bug profile id.
String bugProfileIdObj = request.getParameter("bugProfile" + pId);
// Getting the logged in user
String userId = request.getRemoteUser();
if (bugProfiles == null) {
fetchProfiles = true;
if (bugProfileIdObj == null) {
// setting the bugprofile id as -1 indicates "all profiles" is selected
bugProfileIdObj =(String) session.getAttribute("bugProfileId" + pId);
if (bugProfileIdObj == null) {
bugProfileId = -1;
else {
bugProfileId = Integer.parseInt(bugProfileIdObj);
else {
bugProfileId = Integer.parseInt(bugProfileIdObj);
session.setAttribute(
("bugProfileId" + pId),
Integer.toString(bugProfileId));
//fetching the bug list
bugData =BugWatcherAPI.getbugList(userId, bugProfileId, fetchProfiles);
PortalLogger.logDebug("BugWatcherPortletContent:: got bug data");
if (bugData != null) {
Hashtable htProfiles = (Hashtable) bugData.get("Profiles");
} else {
htStore.put("NoProfiles", "Y");
} catch (CodedPortalException e) {
htStore.put("Error", CommonUtil.getErrMessage(e.getMessage()));
PortalLogger.logException
("BugWatcherPortletContent:: CodedPortalException!!",e);
} catch (Exception e) {
PortalLogger.logException(
"BugWatcherPortletContent::Generic Exception!!",e);
htStore.put(     "Error",CommonUtil.getErrMessage(ErrorConstantsI.GET_BUGLIST_FAILED));
if (fetchProfiles) {
bugProfiles = (Hashtable) bugData.get("Profiles");
session.setAttribute("Profiles", bugProfiles);
// putting the stuff in the context
htStore.put("Profiles", bugProfiles);
htStore.put("SelectedProfile", new Integer(bugProfileId));
htStore.put("bugs", (ArrayList) bugData.get("Bugs"));
return htStore;
=============================================================
And I am trying to call this function as it can capable of fetching the data from the database by "getbugProfiles".
In the new class bugWatcherRefreshAction.java I have coded a part of code which actually clears the caching.Below I am giving the required part of the code:
=============================================================
public void doPerform(RunData rundata, Context context,String str) throws Exception {
JetspeedRunData data = (JetspeedRunData) rundata;
HttpServletRequest request = null;
//PortletConfig pc = portlet.getPortletConfig();
//String userId = request.getRemoteUser();
/*String userId = ((JetspeedUser)rundata.getUser()).getUserName();//sraha on 1/4/05
String pId = request.getParameter("PortletId");
PortalLogger.logDebug("just after pId " +pId); */
//Calling the variable holding the value of portlet id from BugWatcherAction.java
//We are getting the portlet id here , through a variable from BugWatcherAction.java
/*BugWatcherPortletContent bgAct = new BugWatcherPortletContent();
String portletID = bgAct.pId1;
PortalLogger.logDebug("got the portlet ID in bugwatcherRefreshAction:---sraha"+portletID);*/
// updating the bug groups
Hashtable result = new Hashtable();
try {
request = data.getRequest();
String userId = ((JetspeedUser)data.getUser()).getUserName();//sraha on 1/4/05
//String pId = (String)request.getParameter("portletId");
//String pId = pc.getPorletId();
PortalLogger.logDebug("just after pId " +pId);
PortalLogger.logDebug("after getting the pId-----sraha");
result =BugWatcherAPI.getbugList(profileId, userId);
PortalLogger.logDebug("select the new bug groups:: select is done ");
context.put("SelectedbugGroups", profileId);
//start clearing the cache
ContentCacheContext cacheContext = getCacheContext(rundata);
PortalLogger.logDebug("listBugWatcher Caching - removing markup content - before removecontent");
// remove the markup content from cache.
PortletContentCache.removeContent(cacheContext);
PortalLogger.logDebug("listBugWatcher Caching-removing markup content - after removecontent");
//remove the backend content from cache
CacheablePortletData pdata =(CacheablePortletData) PortletCache.getCacheable(PortletCacheHelper.getUserHandle(((JetspeedUser)data.getUser()).getUserName()));
PortalLogger.logDebug("listBugWatcher Caching User: " +((JetspeedUser)data.getUser()).getUserName());
PortalLogger.logDebug("listBugWatcher Caching pId: " +pId);
if (pdata != null)
// User's data found in cache!
PortalLogger.logDebug("listBugWatcher Caching -inside pdata!=null");
pdata.removeObject(PortletCacheHelper.getUserPortletHandle(((JetspeedUser)data.getUser()).getUserName(),pId));
PortalLogger.logDebug("listBugWatcher Caching -inside pdata!=null- after removeObject");
PortalLogger.logDebug("listBugWatcher Caching -finish calling the remove content code");
//end clearing the cache
// after clearing the caching calling the data from the database taking a fn from the portletContent.java
PortalLogger.logDebug("after clearing cache---sraha");
BugWatcherPortletContent bugwatchportcont = new BugWatcherPortletContent();
Hashtable httable= new Hashtable();
httable=(Hashtable)bugwatchportcont.loadContent();
PortalLogger.logDebug("after making the type casting-----sraha");
Set storeKeySet = httable.keySet();
Iterator itr = storeKeySet.iterator();
while (itr.hasNext()) {
String paramName = (String) itr.next();
context.put(paramName, httable.get(paramName));
PortalLogger.logDebug("after calling the databs data from hashtable---sraha");
} catch (CodedPortalException e) {
PortalLogger.logException("bugwatcherRefreshAction:: Exception- ",e);
context.put("Error", CommonUtil.getErrMessage(e.getMessage()));
catch (Exception e) {
PortalLogger.logException("bugwatcherRefreshAction:: Exception- ",e);
context.put(     "Error",CommonUtil.getErrMessage(ErrorConstantsI.EXCEPTION_CODE));
try {
((JetspeedRunData) data).setCustomized(null);
if (((JetspeedRunData) data).getCustomized() == null)
ActionLoader.getInstance().exec(data,"controls.EndCustomize");
catch (Exception e)
PortalLogger.logException("bugwatcherRefreshAction", e);
===============================================================
In the bugwatcher Action there is another function called PostLoadContent.java
here though i have found the portlet Id but unable to fetch that in the bugWatcherRefreshAction.java . I am also giving the code of that function under the bugWatcherAction.Java
================================================
// Get the PortletData object from intermediate store.
CacheablePortletData pdata =(CacheablePortletData) PortletCache.getCacheable(PortletCacheHelper.getUserHandle(
//rundata.getRequest().getRemoteUser()));
((JetspeedUser)rundata.getUser()).getUserName()));
pId1 = (String)portlet.getID();
PortalLogger.logDebug("in the bugwatcher action:"+pId1);
try {
Hashtable htStore = null;
// if PortletData is available in store, get current portlet's data from it.
if (pdata != null) {
htStore =(Hashtable) pdata.getObject(     PortletCacheHelper.getUserPortletHandle(
((JetspeedUser)rundata.getUser()).getUserName(),portlet.getID()));
//Loop through the hashtable and put its elements in context
Set storeKeySet = htStore.keySet();
Iterator itr = storeKeySet.iterator();
while (itr.hasNext()) {
String paramName = (String) itr.next();
context.put(paramName, htStore.get(paramName));
bugwatcherRefreshAction bRefAc = new bugwatcherRefreshAction();
bRefAc.doPerform(pdata,context,pId1);
=============================================================
So this is the total scenario for the fetching the data , after clearing the cache and display that in the portal.I am unable to do that.Presently it is still fetching the data from the cache and it is not going to the database.Even the portlet Id is returning as null.
I am unable to implement that thing.
If you have any insight about this thing, that would be great .As it is very urgent a promt response will highly appreciated.Please send me any pointers or any issues for this I am unable to do that.
Please let me know as early as possible.
Thanks and regards,
Santanu Raha.

Have you run it in a debugger? That will show you exactly what is happening and why.

Issue to send email (using sp_send_dbmail) with an attachement located in other server within the same network

I have two servers. One is for databases (DB) with the mail server configured and the other is for SSIS without mail server. Both servers are in the same network. On the SSIS server the SSIS package exports data from the DB server table
to xls file. The file is saved in SSIS server. When I created a task to send the email (using sp_send_dbmail) to attach that file, I got the error message:
Error: Executing the query "EXECUTE [msdb].[dbo].[sp_send_dbmail]
@profile_na..." failed with the following error: "Attachment file H:\test.xls is invalid.".
Any help will be appreciated. Thanks.
A Fan of SSIS, SSRS and SSAS

Where are you running this?
If its in the other server (DB) you need to use UNC path to the SSIS server folder where file resides
Also the executing account should have access to the folder as well as the file. So If you're running this from a job make sure you either provider folder and file access to sql agent job service account or create a separate proxy account with the required
permissions and configure the job to use the account
