Serializing classes that contain other classes

Hi all,
Hoping someone can answer me a quick question, I'm familiar enough with Java + OO in general but just starting to try to put a multiplayer game framework together so running into a few areas I haven't encountered before... so sorry if this is a bit of a newbie sounding question...
I have a serializable class that contains a reference to another serializable class, very similar to:
public class ClassA implements Serializable
    private ClassB b;
    ...and some other fields...
    public ClassA ()
        super ();
    ...and a standard public getB and setB
public class ClassB implements Serializable
    int someValue;
    ...standard no arguments constructor...
    ...standard getSomeValue and setSomeValue...
}Now that all works fine, serializes fine, send it down an ObjectOutputStream down a network socket, deserializes the other end, all no problem. What I don't like is that to create a ClassA I have to do:
ClassA myClassA = new ClassA ();
myClassA.setB (new ClassB ());   <--- this line
myClassA.getB ().setSomeValue (5);because it could easily be ommitted (especially since the real situation is more complex that two simple classes like above) and I'll get a NullPointerException. Normally (in a non-serialized ClassA) I'd have put b = new ClassB (); in the constructor.
However I don't like the idea of doing that because when deserializing a ClassA, I imagine the deserialization mechanism creates its own ClassB object to set into ClassA? And so if in the ClassA constructor, I create my own ClassB, then the deserialization will then immediately go and create its own ClassB and the ClassB I created will go to the garbage collector, i.e. it was a pointless object to create?
Just wondering what suggestions anyone has on this, there must be a standard approach to deal with this?
Thanks very much,
Nigel.

Allthough you give a lot of information I do not quite understand what you mean, but maybe a little re-arrangement of the setB en getB methods will do it:
public ClassB getB() {
    if(b == null) {
        setB(new ClassB());
    return b;
public void setB(ClassB b) {
    this.b = b;
}

I created a photo book in Photoshop elements 11 that contains png files with the invisible backgrounds. When I export the book to a jpg or a pdf, the png files appear with white backgrounds.

jpg and pdf formats don't support transparency. You need to use a format such as tif, png or psd that does.

Embedding a Button that contains a MovieClip with a filter on it causes a build error in Flex

I'm trying to embed (via [Embed(...)] code) a button that
contains a movieclip with a blur filter on it. This causes Flex to
stop compiling my project (actually it says that it cannot find
another symbol that I'm also embedding). I've narrowed it down to
this problem though.
As soon as I remove the filter on the movieClip, Flex likes
it again.
Does anybody have experience with this or found a workaround?
thanks, Frank Hermes

This is really a SQL issue, not SharePoint. After 5000 rows, SQL does a lock escalation from a row lock to a table lock. The table lock prevents operations on the entire table, hence why you want to stay under 5000 rows, especially for a busy content database.
One way to mitigate this scenario is to dedicate the content database to the Site Collection. This way only the Site Collection is impacted by the lock escalation.
You can also set specific Lists/Libraries to disable the throttle entirely by using PowerShell to set the EnableThrottling property to $false. Alternatively, you can use a sandbox or full trust solution to display the data where it also ignores the throttle.
To answer your question, yes it will fail after 20,000 items.

I cannot create a new business catalyst site with Dreamweaver CC 2014. The error message states that Dreamweaver cannot connect with server, try again later. How can I fix this problem?

I cannot create a new Business Catalyst site with Dreamweaver CC 2014 (Mac). The error message states that Dreamweaver cannot connect with server, try again later. In addition, I am also unable to load remotely a previously created Business Catalyst site as it says there is something wrong with my username or password. However when I put my password in and press test connection, it says it has connected successfully. What is going wrong and how can I fix this problem?
Thanks

Hi Ozy08,
Can you try the solutions mentioned in Re: Can't Login to Business Catalyst within Dreamweaver CS6?

Trouble with compiling class that contains "import com.sun.xacml.*;"

I think the package com.sun.xacml is included in j2sdk 1.4.2 (the one that I have)
but every time I try to compile a class that importes this package classes, the compiler dosen't recognize the package.
It's a problem of updating the CLASSPATH?
Thanks in advance

I don't think this would be part of any standard java distribution.
But I found a couple of jars (versions) available for download at
http://ebxmlrr.sourceforge.net/maven/repository/xacml/jars/

Help needed to define a xsd for a java class that has initialization block

public class Boss{
private String name ;
private String sex;
Boss(String name,String sex){
this.name = name;
this.sex = sex;
I am working on a wsdl first webservices.
Can someone come with an xsd for this two class.I am struggling to come with an xsd becuase of the initialization of boss1 and boss2
Please help.
thx

You will have to write the initilization logic in helper or utility classes.

With out try and catch

with out any try and catch is exception handling is possible in java when doing manupulation with database.
assume mydatabase is oracle,if i am going to insert a record of a primarykey field, which is already existing.i don't want to put with in try and catch.This is my case.if u have the answer for this please mail me.
thanks
rajan

assume mydatabase is oracle,if i am going to insert a
record of a primarykey field, which is already existing.
i don't want to put with in try and catch.why not? i thought the fact that checked exceptions get thrown from methods is a good thing, since you're forced either to deal with the fault immediately, or throw to the next level up, possibly transformed into an application-level exception. if methods were to simply return method-specific error codes, nothing forces anything in the program to deal with errors in a reasonable manner. not that exceptions force sensible handling of the fault--but they do force recognition of the fault.
what alternative do you desire?

Site lookup columns that contain a list with lookup columns help needed

Here is the theoretical scenario,
I have a list called Shirts. The list contains name,color, and size columns.
I have a list called Pants This list contains name, color and size columns as well.
These two lists are contained at the root level of the site. I created site lookup columns for these two lists and used the name, color and size columns as additional fields on both lookup columns. Lets call these lkupPants and lkupShirts.
On a sub site I have a list called people. It contains name,date,lkupPants and lkupShirts columns.
The list looks something like this is dataview:
Name Date lkupPantsName lkupPantsColor lkupPantsSize lkupShirtName lkupShirtColor lkupShirtSize
This is the behavior I expected. The additional columns selected in the site lookup columns appear in the list.
I now create another site lookup column this one is based on the list called people at this subsite level. When creating the site lookup column, the data from lkupPants and lkupShirts are not available.
How can one create a lookup column that contains list data and any lookup columns contained in the list as additional fields.
If anyone can see where I am going with this, can they provide another means to accomplish what I am trying to do?
fr0stsp1re

create additional columns in people list. look up values are available in the workflow so populate the additional columns with the values you need. this will allow you to create another look up column based on this list and all the fields needed.
just a thought.

How do I attach a folder that contains multiple documents? I try and it will only allow me to pick one document at a time.

I'm trying to upload to my school's online blackboard (which is where I submit papers) and I cannot seem to figure out how to upload a folder I made on my desktop. I created multple folders containing more than one document and thought this would be easier then each individual document. But I cannot attach the whole folder. I have to pick each document which I could have done in the beginning!! Any thoughts? I tried to hit shift and then control to highlight all of them but that did not work. Any advice welcome:)

Geiger,
This is what you get when you key the word sections into the help function:
*Creating Sections*
+In a word processing document, a section consists of one or more pages.+
+Each Pages template consists of one or more predefined sections. Every time you add pages to the document by using the Sections (word processing) or Pages (page layout) button in the toolbar, you add a new section.+
+In a page layout document, each page is one section. You can use the predefined sections as they are, or you can modify or remove them one page at a time.+
+In a word processing document, you can use the predefined sections as they are, or you can create or remove section breaks to define your own sections. To add a page to a section, add more content and pages will be automatically added, or insert a page break.+
+Here are ways to work with section breaks in word processing documents:+
+To insert a section break, place the pointer where you want the break to occur, and then choose Insert > Section Break or click Sections in the toolbar and choose an item from the list.+
+When you show invisibles in your document (click View in the toolbar and then choose Show Invisibles), a section break symbol marks the location of the section break.+
+The new section has the same formatting as the previous section until you change it. Changes you make to master objects, headers, footers, or page numbering will apply only to the section in which you make the changes. See Using Master Objects (Repeated Background Images) for information about master objects.+
+To remove a section break, click at the beginning of the line that follows the break and press the Delete key.+

Problem building swc that contains s:SolidColor with manifest file

Hi all,
I have a problem compiling a library with the command line compiler. The problem is that when I don't use a Manifest file, everything compiles as expected. When I specify a Manifest file for building my swc, I get an error "Could not resolve <s:SolidColor> to a component implementation".
My library consists of one class, which is: Test.mxml
<?xml version="1.0" encoding="utf-8"?>
<s:Group xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark">
<s:Rect x="50" y="50" width="100" height="100">
    <s:fill>
      <s:SolidColor />
    </s:fill>
</s:Rect>
</s:Group>
This is my Manifest.xml
<?xml version="1.0"?>
<componentPackage>
          <component id="Test" class="Test"/>
</componentPackage>
This commands gives no error and results in a swc successfully
compc -output TestLibrary.swf -include-classes Test -source-path .
This commands leads to the error "Could not resolve <s:SolidColor> to a component implementation"
compc -output TestLibrary.swf -include-classes Test -source-path . -compiler.namespaces.namespace http://test Manifest.xml -include-namespaces http://test
I think this is the correct way of creating an swc using a Manifest file. Is this correct (so this is a bug?) or am I doing something wrong?

There's nothing about that VI I can imagine causing an error on build. You might try doing a force compile of your app to track it down. Try opening up your top level VI, hold CTRL+Shift and hit the run arrow at the same time. If it gives you a broken arrow, you can bring up the error list to try to find it. Maybe this will help locate the problem. If you haven't already, might not hurt to do a mass compile of the SPC VI's also.

How to access function from Top Class to Function of class that contain the the member variable of TopClass

Dear All,
is there any way that i can access function or member variable of aggregate class.

and making win32 dll with mfc Support. i am new in dll system. just learning and doing.
previously all in exe and i am working this like
CTestDoc*pDoc = (CTestDoc*)GetTestDocument();
somevar = pDoc->xDoc.mVar.GetValue ();
now i am trying to put all in dll. so getting problem
will i get help on this. thanks in advance.
below code is just an example.
for example
// dll 1
class aaa : public BaseClass

if (GetCurBColor() == 125) // how to access GetCurBColor function of the
color = GetCurBColor();
long color;
// dll 2
class bbb :public BaseClass
public:
int Index;
long lSize;
long color;
void doSometing();
// dll 3
class DDD
public:
vector <aaa> va;
vector <bbb> vb;
int cura;
int curb;

What problem?
The rules of C++ do not change because some of the code ins in a DLL. But the classes in a DLL need to be exported. See for example
https://msdn.microsoft.com/en-us/library/81h27t8c.aspx
You should also supply a macro so that the class header can be used in both the DLL and the client. See for example
http://stackoverflow.com/questions/14980649/macro-for-dllexport-dllimport-switch
If you exchange memory between the DLL and the client (as your example will do, because of the std::vector content), you should also be sure to use the same version of the compiler for each module, and to dynamically link to the CRT.
I would also advise you to start with a less complicated scenario, with just one DLL.

WebI report on SAP Mobile BI for iOS that contains a chart with element linking issue

Hi gurus. I have the following issue:
I have element linking based filters on my chart # 1 to filter values on chart # 2. It worked fine on Ipad. And it worked fine on BI Launch Pad.
But after some time I check my webi report and it stopped working on IPAD.
Filters are not shown on the graph.
However it still works fine on BI LaunchPad
Have you faced this issue before?
Using: BI mobile 5.1.12
Before, example:
After some time, I opened sap mobile and it is not showing up the filter anymore
Now: We upgraded to SAP Bi Mobile 6.0.8.12 but issue persists.
Could you do the test?
Steps to reproduce:
Create a simple Webi report with a table.
Copy that table and paste it to the report.
Turn the original table into a column chart
Add element linking from the chart to table. (When user filters on the chart it should change the table as well)
Test that the element link works in BI LaunchPad.
Save the report to the Mobile category and test on iPad.
Open report on iPad
Tap chart bars. Yellow filters, that are supposed to show up, are not displayed.

Hi Erika,
Is this report element linking defined as 'All Objects' or 'Single Object' in Webi.
I ask this that report element linking on 'All Objects' is not supported yet. This support is expected to come in later releases.
However, if this is single object then it should be working. Can you verify this on latest app store build and confirm. If still it does not work for you, then please raise a support ticket for the same.
Regards,
Ashutosh

Making a PDF that contains multiple jpegs with captions

Hi - I am not very savvy technically and need to create a PDF document with multiple jpeg images with captions. Is it best for me to do this online by using the "convert to PDF" service at acrobat.com? I would like to know if it will be easy for me to upload and label 4-5 images and then make that into a PDF before I pay the monthly fee. I appreciate any help I can get!! Thanks.

CreatePDF doesn't have a word processing tool but you could do this using the Acrobat.com service to do this. Acrobat.com has a word processing tool and the ability to convert your file to PDF. You can test at this capability with a free trial.
