Cannot resolve PIM in WSDD 5.7.1
I installed PIM package on WSDD 5.7.
I get unresolved external error when I include the following line in my source code.
import javax.microedition.pim.*;
Thanks in advance
Hai VijayJadhav,
Have you included the PDAP-PIM library to your project. If not, do so and then check
To include those libraries, please follow the following
1. From the Project menu, select Properties
2. select Java Build Path from left side of the window
3. select Library tab from the right side of the window
4. Click Add Library button
5. select WebSphere Everyplace Technology Library and click next
6. Unfold 2.2.0 folder and then select WTL PDAP-PIM
7. click Finish
8. Click Add Library button
9. select J2ME Library and click next
10. Unfold 2.2.0 folder and then select JCL MIDP 2.0
11. click Finish

Problem with DNS - ping/Safari cannot resolve, but host/dig work OK
Hi All,
Have a weird problem with DNS which is a bit similar to the following ones:
http://discussions.info.apple.com/thread.jspa?threadID=2190208
http://forums.macrumors.com/showthread.php?t=337942
I connect with remote internal network via OpenVPN and from time to time (yes, intermittent problem :)) internal DNS names cannot be resolved.
When it happens I can still resolve names using host or dig utilities, but applications (like Safari) and ping cannot resolve them.
resolv.conf has proper DNS server set:
*$ cat /etc/resolv.conf*
*# Mac OS X Notice*
*# This file is not used by the host name and address resolution*
*# or the DNS query routing mechanisms used by most processes on*
*# this Mac OS X system.*
*# This file is automatically generated.*
*domain openvpn*
*search openvpn*
*nameserver 10.0.0.1*
More than that - it can resolve those internal names when queried directly, for example using host:
*$ host YYY.XXX.ru 10.0.0.1*
*Using domain server:*
*Name: 10.0.0.1*
*Address: 10.0.0.1#53*
Aliases:
*YYY.XXX.ru has address 192.168.x.y*
but at the same time ping reports "*Unknown host*":
*$ ping YYY.XXX.ru*
*ping: cannot resolve YYY.XXX.ru: Unknown host*
I tried "*dscacheutil -flushcache*" and it did not help. Also tried to comment out domain and search directives in resolv.conf and it did not help as well (and actually it should not matter).
Any ideas why this can happen and what else can I check when it happens again?
Thanks!I have the same issue. It cropped up after I installed updates to MS Office 2008 and Firefox in which I also saw issues with the icons disappearing in the dock of the applications that were open when I started the Office update. I rebooted to try to get them back, but ended up deleting them and restoring from the Applications folder. I don't know if that's a red herring or not, but I generally try to figure out what has recently changed that may cause something to suddenly start failing.
I'd been working successfully all morning before it started acting up. Switching from wifi to cat5 had no effect.
@realaaa, were you able to resolve without a major undertaking, like reinstalling your OS?

Visual Studio 2012 cannot resolve symbol or Errors control is not a member of class
Visual Studio 2012 Web Site Project (Note not a Web application, so there are not Designer.vb files) > Site works perfectly fine and using IIS and attaching to IIS to debug code.
However, if I try to build the site inside of Visual Studio I am getting lots of Errors ‘pnlName’ is not a member of ‘Page_Name’ In the code behind I am getting errors ‘Cannot resolve symbol ‘pnlName’
.ascx Page
<li style="margin-right:0;" id="pnlName" runat="server"><a href="/cart" title="Checkout" class="global-checkout">Checkout</a></li>
.ascx.vb page
Me.pnlName.Attributes.Remove("style")
I have cleaned, rebuild and nothing gets rid of these errors, but again the site works as designed, but I would like to launch and debug inside of Visual Studio.

http://moojjoo.blogspot.comCor,
What I am stating is this is a solution using the Web Site Project instead of a
Web Application Project.
Web Site projects do not require Designer.vb files, Web Application Projects add Designer.vb files in the solution.
Background: I have been hired to support a very successful e-commerce site that was built by a 3rd party vendor (I had no input on the contract or specification, because I would have went with
MVC). The site works 100% correctly, however from my 2003 - 2015 experience with Visual Studio and Web Development being in Web Forms and MVC I have always built ASP.NET Solutions using the Web Application Project Templates, which compiles the code down
to .dlls.
A Web Site project does not compile the code, but simply uses the .vb files and they have to be migrated to the server with the .aspx files. http://msdn.microsoft.com/en-us/library/dd547590%28v=vs.110%29.aspx
Currently the only way I can debug this Solution is to attach to the w3wp.exe process running locally on my work station.
The Solution is comprised of two Web Sites, which I cannot get it to compile because of the following errors -
'webServerControlName' is not a member of '(Protected Code Behind Class Name)' I am reaching out to the MSDN community to see if anyone has experienced this issue with
Web Site Projects.
I hope that clears up the Project Type question.

I am using Sun JDK Version 1.3.0_02" and Apache/Tomcat 4.0. Both the calling and the called class are in the same directory.
Any help would be greatly appreciated.
tnx..
addiIs ConnectionPool in this "cal" package as well as PooledConnection? From the directory you are compiling from it appears that it is. If it is, then you are compiling it incorrectly. To compile ConnectionPool (and PooledConnection similarly), you must change the current directory to the one that contains cal and type
javac cal/ConnectionPool. -
Missing method body and cannot resolve symbol
I keep getting these two errors when trying to compile. I know that I need to call my fibonacci and factorial functions from the main function. Is this why I am getting the missing method body error? How do I correct this?
Am I getting the cannot resolve symbol because I have to set the num and fact to equal something?
Thanks
public class Firstassignment
public static void main(String[]args)
System.out.println();
public static void fibonacci(String[]args);
int even=1;
int odd=1;
while (odd<=100);
System.out.println(even);
int temp = even;
even = odd;
odd = odd + temp;
public static void factorial (String[]args);
for (int count=1;
count<=num;
count++);
fact = fact * count;
outputbox.printLine("Factorial of" + num + "is" + fact);Hey... :o)
the problem is that you've put semicolons at the end of the function signature, like this:
public static void fibonacci(String[]args);
}that should happen only when the function is abstract... so ur function should actually look like this:
public static void fibonacci(String[]args)
}also, i think you've missed out on the declarations (like what are fact and num??).... -
Compc: cannot resolve mx:Object to a component implementation
Hi,
I need to migrate a component library to Flex 3.0 but i am
running into problems with one simple component when trying to
build the swc by the compc command line tool from within an ant
script. In FB3.0 the library is created as expected without any
errors. So here is my component:
quote:
<mx:ApplicationToolbar xmlns:mx="
http://www.adobe.com/2006/mxml".....>
<mx:Object id="xyz">
</mx:Object>
</mx:ApplicationToolbar>
Using flex 3.0 compc I get the mentioned error:
"cannot resolve <mx:Object id="xyz" to a component
implementation"
What is wrong? Why the compiler does not complain when using
FB 3.0 ?
(Compiling with flex 2.0.1 compc works fine too)
Hope someone can help me.
Thanks in advance,
Andreas.Hi,
Object is a top-level class, so i do not have to import it.
Fortunataly, I found the solution. I had to include the
following into my ant build script:
quote:
<compc ...>
<load-config
filename="${FLEX_HOME}/frameworks/flex-config.xml"/>
</compc>
Now the library is compiled as expected! -

Gumbo in Flex builder 3: cannot resolve FxApplication to component implimentation
Hello everyone,
I've been banging my head on the keyboard over this issue for a while. I've downloaded and successfully installed 2 seperate versions of the nightly Flex Gumbo SDK 4.0.0.6831 and 4.0.0.6898 (two versions because i had first assumed that the error was a nightly bug). I've set the Flex compiler to use the new 4.0.0.6898 build and changed the Require flash player version to 10.0.0. Everything set right?
so i put this:
<Application xmlns="http://ns.adobe.com/mxml/2009" layout="absolute">
<FxButton label="Hello World" />
</Application>
and get the error at compile time: Gumbo in Flex builder 3: cannot resolve <FxApplication> to component implimentation. I've tried everything: <Application>, changed the namespaces, and more. Any other ideas?
Thank you in advance -brandonTry something like this:
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/halo">

entry= new Entry(name, address, phone);
entry.writeToFile(outFile);
System.out.print("Enter first name: ");
first=in.readLine();
outFile.close();
}OK. Here is how I did it.
I have AddressDr which is Address driver.
I have two files Address and Entry which in package addressBook.
AddressDr:
import java.io.*;
import addressBook.*;
public class AddressDr
public static void main(String[] args)throws IOException
Name name;
Address address;
Phone phone;
Entry entry;
String first, last, middle, street, city, state, zip;
int areaCode, number;
BufferedReader in;
in=new BufferedReader(new InputStreamReader(System.in));
PrintWriter outFile;
outFile=new PrintWriter(new FileWriter("Entries"));
System.out.println("Quit entered fot the first name ends the " + "application.");
System.out.print("Enter first name: ");
first=in.readLine();
while (first.compareTo("Quit") !=0)
System.out.print("Enter last name: ");
last=in.readLine();
System.out.print("Enter middle name: ");
middle=in.readLine();
name=new Name(first, last, middle);
System.out.print("Enter street address: ");
street=in.readLine();
System.out.print("Enter city: ");
city=in.readLine();
System.out.print("Enter state: ");
state=in.readLine();
System.out.print("Enter ZIP code: ");
zip=in.readLine();
address=new Address(street, city, state, zip);
System.out.print("Enter areaCode: ");
areaCode = Integer.parseInt(in.readLine());
System.out.print("Enter number: ");
number=Integer.parseInt(in.readLine());
phone=new Phone(areaCode, number);
entry= new Entry(name, address, phone);
entry.writeToFile(outFile);
System.out.print("Enter first name: ");
first=in.readLine();
outFile.close();
Entry:
package addressBook;
import java.io.*;
public class Entry
Name name;
Address address;
Phone phone;
public Entry(Name newName, Address newAddress, Phone phoneNumber)
name = newName;
address = newAddress;
phone = phoneNumber;
public Name knowName()
return name;
public Address knowAddress()
return address;
public Phone knowPhone()
return phone;
public void writeToFile(PrintWriter outFile)
outFile.println(name.knowFirstName());
outFile.println(name.knowLastName());
outFile.println(name.knowMiddleName());
oufFile.println(address.knowStreet());
outFile.println(address.knowState());
outFile.println(address.knowCity());
outFile.println(address.knowZip());
outFile.println(phone.knowAreaCode());
outFile.println(phone.knowDigits());
Address:
package addressBook;
public class Address
String street;
String city;
String state;
String zipCode;
public Address(String newStreet, String newCity, String newState, String zip)
street=newStreet;
city=newCity;
state=newState;
zipCode=zip;
public String knowStreet()
return street;
public String knowCity()
return city;
public String knowState()
return state;
public String knowZip()
return zipCode;

Recieving cannot resolve symbol symbol : class Serializable
I'm receiving the error:
cannot resolve symbol symbol : class Serializable
The class is as follows:
//package cscie160.hw5;
import java.io.Serializable
* @author Eddie Brodie
* @version %I%, %G%
public class AccountInfo implements Serializable
public int _accountNumber;
public int _pin;
public AccountInfo(int accountNumber, int pin)
_accountNumber = accountNumber;
_pin = pin;
I've tried importing java.*
I've also checked my classpath.
Any ideas?Try taking the import statement out of the comment block; that might help

Cannot resolve symbol: class OracleDriver
Attempting to compile a servlet on Apache Server using same jdeveloper jdbc libraries:
classes12.jar & nls_charset12.jar
Error message:
$compilejava2.sh ProdJobs
ProdJobs.java:361: cannot resolve symbol
symbol : class OracleDriver
location: package driver
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Am I missing something else?
JeffreyEnter this code into your program and then put the Oracle jar file that contains the driver in your run-time classpath.
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
catch(ClassNotFoundException cnfe) {
// driver not found
}The effect of this is that the classloader will load the Oracle driver for you then call it's static initiailizer that does a bunch of magic that results in the Java runtime knowing that there's a JDBC driver out there.
It is a little weird - but that's the way it works. -

Also the following enviorment varibales have been set to:

Path
%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\Common Files\Adaptec Shared\System;%JAVA_HOME%\bin;%J2EE_HOME%\bin
I can run j2EE, like "j2EE -verbose" (no problems)
also run cloudscape, like "cloudscape -start" (no problems)
also can run deploytool, like "deploytool" (no problems, & deploy sample ear files from cd book)
Your help is appreicated.
