Error in hashtable
Hi,
i have the following code. the hashtables have been defined at class level.
public void calculateUserDetails()
Enumeration objEnumKeys = hashAllDetails.keys();
while(objEnumKeys.hasMoreElements())
String strHashKey = (String)objEnumKeys.nextElement();
UserDetails objUserDetails = (UserDetails) hashAllDetails.get(strHashKey);
intBasicPacksTotalCount += objUserDetails.CountBasicPacks;
intAdvancedPacksTotalCount += objUserDetails.CountAdvancedPacks;
int intCurrentUserSoldSmsCount = getSoldSmsCountToUser(objUserDetails);
intTotalSoldSmsCount = intTotalSoldSmsCount + intCurrentUserSoldSmsCount;
int intCurrentUserUtilizedSmsCount = intCurrentUserSoldSmsCount - objUserDetails.SmsBalance;
intTotalUtilizedSmsCount += intCurrentUserUtilizedSmsCount;
intActivePacksCount += getUserActiveSMSPacksCount(objUserDetails, intCurrentUserUtilizedSmsCount);
int intTotalCountPackPurchased = packPurchased(objUserDetails);
hashABCD= new Hashtable();
hashABCD.put("tPackPurchased",intTotalCountPackPurchased);
hashABCD.put("UserUtilizedSmsCount",intCurrentUserUtilizedSmsCount);
hashABCD.put("SmsBalance",objUserDetails.SmsBalance);
boolean newFlag=NewUser(objUserDetails);
if(newFlag==true)
hashABCD.put("NewUser","Yes");
else
hashABCD.put("NewUser","No");
hashDisplay.put(objUserDetails.UserId,hashABCD);
} //End while
} UserDetails is my class.

3 errors
please help me out.
hi,
Thanks a lot .
Do i wrap int into an integer using
Integer.parseInt() ???
please help.Use the constructor, unless you're using java 1.5, in which a static method valueOf(int) has been introduced.

hi all,
in the following code, I get an error in the "find()" method in
this statement
comparedURL = (Document)ht.get(findElement);
It gives me a null ptr exception..
any ideas...?
Here is the code
static void compareDocuments ( Hashtable ht )
Enumeration keys = ht.keys();
Document doc = null;
String findElement = "";
try
while ( keys.hasMoreElements())
doc = (Document ) ht.get(keys.nextEleme());
for(int h=0;h<doc.getOutgoingLinks().size();h++)
findElement = (String)doc.getOutgoingLinks.elementAt(h));
find ( ht,doc,findElement);
catch ( .... )

one of the keys that you are passing to the get method
as well.This is what the hashtable contains

Error in Hashtable put method-Can not resolve symbol
Hi there!I am new to using java.util.Hashtable.
I am using it for a command line instant messaging program for holding the list of clients and list of client names currently connected to the server.
However when I compile my server with the command javac server.java it seems to give errors can not resolve symbol method put (java.lang.object,int).

Why do I get this error with hashtables
This is the first time I am using hashtables. I tried to make a simple example using these lines
Hashtable dates = new Hashtable ();
dates.put("christmas", "25 Dec");but I end up getting these errors:
RLearner.java:9: <identifier> expected
dates.put("christmas", "25 Dec");
^
RLearner.java:9: package dates does not exist
dates.put("christmas", "25 Dec");
^can you please tell me why I get these errors, I think I've included all the packages, but again, Im not sure
Thanximport java.util.Hashtable;
public class test {
public static void main(String[] args) {
Hashtable test = new Hashtable();
test.put("christmas","25 Dec");
} -
I just discovered hashtables :D mmm.. i find hashname.put(object, object); to be too much.. so i wrote a adhoc method for walking through two arrays and putting them into hastables :D though, i had some errors:
public Hashtable makeHash(int cap, String allString[], int allInt[])
Hashtable hash = new Hashtable(cap);
int i = 0;
while(i < allString.length && i < allInt.length)
hash.put(allString, new Integer(allInt[i]));
i++;
return hash;
then i ran this method:
String days[]=
"Sun",
"Mon",
"Tue",
"Wed",
"Thu",
"Fri",
"Sat"
offset[] = {0, 1, 2, 3, 4, 5, 6};
makeHash(7, days[], offset[]);in eclipse, there is a red mark under the comma right after days[] in the makeHash parameter... when i mouse over it, it gave me an "Syntax error on token ",","." expected".. anyone know what i'm doing wrong?int[] offset = {0, 1, 2, 3, 4, 5, 6} ; is valid, and, I think int offset[] = {0, 1, 2, 3, 4, 5, 6}; However, I don't think offset[] = <whatever> is valid anywhere except as part of the delaration. After declaring int[] offest or int offset[], you just use offest without the [] to refer to the array.

Infinite loop - "Some actions taken while...offline could not be completed"
I have 4 IMAP accounts (.Mac, Gmail and 2 at SpamArrest). Occasionally, I get in this infuriating state where I keep getting the following error:
"Some actions taken while the account "ClickMarkets-SA" was offline could not be complete online.
Mail has undone actions on some messages so that you can redo the actions while online. Mail has saved other message in mailbox "INBOX.Sent Messages" in "On My Mac" so that you can complete the
actions while online.
Additional information: The connection to the server "mail.spamarrest.com" on port 993 timed out."
The only way I've found to resolve this infinite loop of messages (which subsequently backs up all other mail processing) is to quit mail, then cd to ~/Library/Mail/[email protected]/.OfflineCache and delete everything in there then relaunch mail.
In each cases, I end up with a mailbox folder (Sent or Drafts) in the folder "On My Mac" which has one copy for each attempt at handling the message "online."
I opened up the Connection Doctor and looked at the log details and saw that Mail is opening a socket to spamarrest and starting an APPEND operation on my INBOX.Drafts folder -- I have "store drafts on server" checked. It appears the APPEND operation is hanging and causing a timeout (see transcript below). This happens every 60 seconds. The error that I see after the timeout is:
* BYE [ALERT] Fatal error: INTERNAL ERROR: Keyword hashtable memory corruption.: Input/output error
Who's Fatal error is that?
SpamArrest is trying to tell me the problem is with both of my computers and not their server. (Yes, this is hitting both my MacBook Pro and my iMac). Can anyone shed some more light on this? IMAP should be able to handle multiple computers so I don't see that as a problem. Is my Mail app not following protocol? Is it a filesystem issue (e.g. SpamArrest doesn't like the name of the folder)?
Thanks.
Chip

Difficult: How to write a SplitInputStream?
Hi,
I am trying to implement a SplitReader. The basic concept is "shared behavior, cloned data".
Let me explain.. Given a parent InputStream, users can retrieved unlimited amounts of children-inputstreams. These children mirror parent behavior in every possible way. If the parent read() throws a IOInterruptedException after 30 seconds (say the parent is a SockeReader) the children should show the same behavior. This does not mean to say that the moment the parent object throws a IOInterruptedException all children should experience the same; rather, the implementation of the children read() should be identical to the parent read().
Furthermore, while behavior is "shared", the data is distinct. If data is recieved by the parent stream, they are immediately "pushed" into all the children streams. If one child reads off its stream, this does not remove data away from any of the other streams; in this way their state is distinct.
So far, I have managed to implement the data-mirroring aspect of SplitInputStream (ie: each stream gets a copy of the parent data) but I have no idea how to "share" the parent behavior across all children. Ideally I want this class to work for all future subclasses of InputStream which may not exist yet. The behavior "sharing" should be generic enough such that it'll automatically work for all future uses of this class.
Can anyone please help or throw some ideas my way? The more discussion the better!
Thanks,
Gili
(email = [email protected])I'm not sure that I fully understood what was it that you wanted, but here is my stab at it.
I understood that you want the errors to appear to the children as they appear to the parent stream, but only when the "child" stream encounters that same spot where the error occurs. If so, then what you have to do, is "tag" the spots where the error occured.
These code fragments contain only some relevant code, but should portray the idea.
public ParentStream extends SomeInputStream {
private String data = "";
private int errorCode = -1;
private Hashtable errors = new Hashtable();
public ChildStream cloneStream() {
return new ChildStream(data);
public void doReading() {
try {
data += super.read(); // Or whatever...
} catch(Exception e) {
errors.put(new Integer(errorCode--),e);
data += errorCode;
public Throwable getError(Integer errCode) {
return errors.get(errCode);
public ChildStream {
private String data;
private ParentStream parent;
int index = 0;
public ChildStream(ParentStream parent, String data) {
this.data = data;
this.parent = parent;
private int read() {
int i = data.charAt(index++);
if(i < 0) { // Error...
try {
// This is done using reflection so that the stacktrace will point to the correct
// place, not the parentstream, but each of the child streams
Class _cl = Class.forName(parent.getError(new Integer(i)).getClass());
Constructor const =
_cl.getDeclaredConstructor(new Class[]{new String("").getClass()});
throw (Throwable)const.newInstance(new Object[]{parent.getError(new Integer(i))});
catch(Exception e) {
e.printStackTrace();
}Hope this made any sense ;).

How to programmatically set the Visibility of an Iview INVISIBLE ?
Hi ..... I need to programmatically set the visibility of an IView for a user Invisible - In order to achieve that , I am trying the below code....But getting errors-
Code -
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sapportals.portal.pcd.gl.PcdInitialContextFactory");
env.put("com.sap.portal.jndi.requested_aspect","com.sap.portal.pcd.gl.PersistencyAspect");
env.put("java.naming.factory.object", "__IPcdContext__");
InitialContext iCtx = null;
String iViewID = "pcd:portal_content/ABC/1Portal/mywork/iviews/XYA_iViews/adf.ivw_ess_jspdynpage";
iCtx = new InitialContext(env);
IiView result =(IiView)iCtx.lookup(iViewID);
IiViews iViewSrv = (IiViews)PortalRuntime.getRuntimeResources().getService(IiViews.KEY);
INewObjectDescriptor IVtoCreate =(INewObjectDescriptor) iViewSrv.instantiateDescriptor(CreateMethod.NEW,"par:/applications/com.sap.km.cm/components/navigation",request.getUser());
IVtoCreate.putAttribute("com.sap.portal.navigation.invisible", true);
the above method putAttribute is not apllicablt for (String,Boolean)\
Please suggest as to how can I programmatically set an Iview Visible/Invisible .I think the property is com.sap.portal.navigation.Invisible with a capital I for invisible...
This blog has an example: Hiding portal role content with a simple iView -
JNI and Native Threads Doesn't work
I am writing a wrapper class in C++ for a java class that publishes a message to JMS. In the C++ code I create the class, and call the one method. Everything does what it is supposed to, UNLESS more than one thread calls it. All the C++ wrapper stuff is in a DLL, and the classpath is correct for the java side, I then run an exe that is linked with the dll. The dll exposes one method that creates the java class, and calls the method. when more than one thread enters the DLL, I start getting class not found exceptions?? where as if I just call the method multiple times in a single thread, all works fine?? Please help, code included

How to verify if user already exists in MySQL database using JSP?
Hi, I am trying to create a website that allows users to register and then login. All regsitration details are stored in a MySQL table and I am attempting to have a java bean check that a new user does not already exist by looking up the username. However, I cannot get this to work, the bean is allowing anyone through. I believe there may be a problem with my while loop as the bean checks through the stored usernames in the database. Any suggestions appreciated thanks. See my code below:[
code]package foo;
import java.sql.*;
import java.util.*;
public class FormBean {
private String firstName;
private String lastName;
private String email;
private String userName;

errors.put("lastName","Please enter your last name");
lastName="";
allOk=false;
if (email.equals("") || (email.indexOf('@') == -1)) {
errors.put("email","Please enter a valid email address");
email="";
allOk=false;
if (userName.equals("")) {
errors.put("userName","Please enter a username");
userName="";
allOk=false;
try {

while(rst.next()) {
DbUserName=rst.getString("u_name");
if (userName.equals(DbUserName)) {
allOk=false;
errors.put("userName","User name already exists, please choose another");
userName="";
conn.close();
break;
} catch (Exception ex) {
ex.printStackTrace();

I tried reading into prepared statements, and although I now understand their basics, I still have no idea why I'm getting this error? -
Mail cannot clear Drafts in .OfflineCache but can save to Drafts on server
OK, I've been chasing this problem (and other related issues) for three days now and I'm at wits end.
I see that I am not alone with the the Mac Mail app getting stuck with messages in its .OfflineCache folder for an email account that it can not process. The common response is to quite Mail, and delete the contents of .OfflineCache, if not the whole directory.
In the case in front of me now, I have 7 versions of a draft message (destined for "Drafts"), a delete of that draft message and a copy of that message destined for "Sent Messages". Obviously, for a while Mail could not execute these commands to the IMAP server at SpamArrest.
What I don't understand is why can I continue to save new files to Drafts and Sent Messages but the .OfflineCache cannot clear itself?
I don't want to just delete the files in .OfflineCache (partly because I need the one in Sent Messages) but I because that is just treating the symptom and not fixing the recurring problem of messages ending up .OfflineCache on a fairly regular basis.
Why can't Mail clear the .OfflineCache?I keep looking at the IMAP protocol output from the Connection Doctor and I'm stymied at why I'm getting a time out. In tracing the log, I see us connect on port 993 with thread 0x187564f0:
CONNECTED May 24 23:00:28.046 [kCFStreamSocketSecurityLevelNegotiatedSSL] -- host:mail.spamarrest.com -- port:993 -- socket:0x1917bbc0 -- thread:0x187564f0
We then start a new thread 0x191581a0 which performs all the subsequent actions including the APPEND:
WROTE May 24 23:00:29.286 [kCFStreamSocketSecurityLevelNegotiatedSSL] -- host:mail.spamarrest.com -- port:993 -- socket:0x1917bbc0 -- thread:0x191581a0

X-Uniform-Type-Identifier: com.apple.mail-draft
From: Chip Roberson <[email protected]>
The next thing I see is a timeout on thread, 0x191581a0:
READ May 24 23:01:29.355 [kCFStreamSocketSecurityLevelNegotiatedSSL] -- host:mail.spamarrest.com -- port:993 -- socket:0x1917bbc0 -- thread:0x191581a0
* BYE Disconnected for inactivity
It would seem that my client is in a wait state, waiting for a response from the WRITE which it does not get a response. Given that I have written to this Drafts folder before, I know it can be done but right now I can't.
SpamArrest swears they don't see anything on their side and that the problem must be on my Mac but what could it be?
The only other clue is that immediately after the Disconnect message, I get the hashtable error:
READ May 24 23:01:29.437 [kCFStreamSocketSecurityLevelNegotiatedSSL] -- host:mail.spamarrest.com -- port:993 -- socket:0x1917bbc0 -- thread:0x187564f0
BYE [ALERT] Fatal error: INTERNAL ERROR: Keyword hashtable memory corruption: Input/Output error
That seems to be a direct result of the timeout but it's hard to know for sure. I wish I knew what "keyword hashtable".
I've done all the standard stuff (e.g. rebuilding, reindexing, permissions, etc.) so I'm struggling to find something else to do. I just wish I could get some more visibility into the problem. Given the symptoms I'm seeing in other threads in this forum, I don't think I'm on the only one with this problem. Am I? -
Hello,
Since 2 days I have every minute a "time out" pop up on mail app regarding my imaps accounts.
I own the mailserver so i know that the problem doesnt come from there.
What should i do ?
I dont really want to delete the pref & cache because it is huge mailboxes and here in Australia we have some internet quota...
help..Jerume,
Search this forum for the string ".OfflineCache" and you'll find several messages describing how to fix this problem in the short term.
What has happened, I think, is that at some point you were editing a message (and possibly sent it) and Mail.app thought you were offline so it saved the drafts files and sent message in the .OfflineCache in ~/Library/Mail. The problem I'm having is that when that happens, Mail.app is never able to clear the .OfflineCache once you go online again.
The net result is that every minute it tries to resend the message and fails, in my case with a timeout and INTERNAL ERROR: Keyword hashtable memory corruption:
READ May 19 17:14:13.626 [kCFStreamSocketSecurityLevelNegotiatedSSL] -- host:mail.spamarrest.com -- port:993 -- socket:0x189d0050 -- thread:0x1d314d10
* BYE Disconnected for inactivity.
* BYE [ALERT] Fatal error: INTERNAL ERROR: Keyword hashtable memory corruption.: Input/output error
I have not been able to figure out how to resolve this from my end. SpamArrest swears it's not their problem.

Use string as identifier in array?
hi, is it possible to use String as identifier in arrays instead of numbers? if so, how do you do it?
lol.. mmm.. well, i just discovered hashtables :D mmm.. i find hashname.put(object, object); to be too much.. so i wrote a adhoc method for walking through two arrays and putting them into hastables :D though, i had some errors:
public Hashtable makeHash(int cap, String allString[], int allInt[])
Hashtable hash = new Hashtable(cap);
int i = 0;
while(i < allString.length && i < allInt.length)
hash.put(allString, new Integer(allInt[i]));
i++;
return hash;
then i ran this method:
String days[]=
"Sun",
"Mon",
"Tue",
"Wed",
"Thu",
"Fri",
"Sat"
int offset[] = {0, 1, 2, 3, 4, 5, 6};
makeHash(7, days[], offset[]);in eclipse, there is a red mark under the comma right after days[] in the makeHash parameter... when i mouse over it, it gave me an "Syntax error on token ",","." expected".. anyone know what i'm doing wrong?
