No need to add 'throws' when throwing IllegalArgumentException ?

Why is it necessary to add throws/try catch when throwing Exception but not when throwing IllegalArgumentException :
public void test(String a, String b) {
    if(a.equals.b) {
          // Do stuff
    } else {
      throw new IllegalArgumentException("bla"); // Ok!
      // throw new Exception("bla");       NO GO!
}

Also, it is usually less than helpful to throw Exception. Try to find the correct subclass exception to provide better info the the poor schmuck who has to handle your exception. Write your own ... it is very easy.

Throws IllegalArgumentException when use BufferedReader.readLine()

hi
when i use BufferedReader.readLine() to read a html file of Internet,it throws IllegalArgumentException like blow:
java.lang.IllegalArgumentException
at java.nio.Buffer.position(Buffer.java:218)
at java.nio.charset.CharsetDecoder.decode(CharsetDecoder.java:575)
at sun.nio.cs.StreamDecoder$CharsetSD.implRead(StreamDecoder.java:442)
at sun.nio.cs.StreamDecoder.read(StreamDecoder.java:182)
at java.io.InputStreamReader.read(InputStreamReader.java:167)
at java.io.BufferedReader.fill(BufferedReader.java:136)
at java.io.BufferedReader.readLine(BufferedReader.java:299)
at java.io.BufferedReader.readLine(BufferedReader.java:362)
but it occured sometimes or occured never in a long time!
Why?

It does it because of this bit of code in java.nio.Buffer.position
if ((newPosition < 0) || (newPosition > limit))
throw new IllegalArgumentException ();So for some reason a bit of the java code has tried to set the position to either less than zero or greater than the limit of the buffer. Not a good idea in either case.
Since this is not your code you can't really do much about it. Try catching the exception and handling it.

I need to add a gap between songs when burning a CD

I just upgraded to iTunes 9.2.0.61, hoping that it would solve my problem. I need to add (yes, ADD) a gap between songs. I'm burning a CD to be used during a performance, and there's a reason that I need 10 seconds of silence after the first song. I believe in previous versions I could add a gap between songs...using Get Info, then Options, but now it just gives me a start and end time for songs. How can I add a 10 second gap between the first two songs?

Add a track consisting of 10 seconds of silence. I made you one in crystal clear MP3 stereo. You can get it here: http://rcpt.yousendit.com/907964971/c4d2c9e22762a8911f4e431a1e2a4e2c
Just put it in the library and then add it to your playlist wherever you need it.
iTunes lets you add a gap between songs, but only up to 5 seconds, and it has to be the same every time.

Need to add Run time Validation in Advanced table column

Hi Friends,
I've an requirement to add the validation in Advanced table.
issue is, In eAM Work Order, currently we have ability to add Operation Seq Number as 0, but we need to add one validation to avoid 0 value.
Oracle gave us the patch but we cannot apply the patch which is bring up the eAM version to higher level.
decided to handle it in controller and made changes to the handleOpSummaryEvent event.
Below is my code.
if("handleOpSummaryEvent".equals(s))
OAApplicationModule oaapplicationmodule = oapagecontext.getApplicationModule(oawebbean);
String wipEntityID = ((Number)oapagecontext.getTransactionValue("WipEntityId")).toString();
oapagecontext.writeDiagnostics(this, (new StringBuilder()).append("Inside wip entity Id: ").append(wipEntityID).toString(), 2);
String opSeqTrans = (String)oapagecontext.getTransactionValue("SelectedOpSeq");
String op = oapagecontext.getParameter("OpSeqSummary");
oapagecontext.writeDiagnostics(this, (new StringBuilder()).append("Inside op : ").append(op).toString(), 2);
oapagecontext.writeDiagnostics(this, (new StringBuilder()).append("Inside operation Seq Value: ").append(opSeqTrans).toString(), 2);
ViewObject vo = oaapplicationmodule.findViewObject("OperationSummaryVO");
if (!vo.equals(null))
oapagecontext.writeDiagnostics(this, "Inside vo not equals to null", 2);
vo.setWhereClauseParam(0,wipEntityID);
vo.executeQuery();
int fetchedRowCount = vo.getRowCount();
oapagecontext.writeDiagnostics(this, (new StringBuilder()).append("Inside fetched row count : ").append(fetchedRowCount).toString(), 2);
if(fetchedRowCount > 0)
RowSetIterator iter = vo.findRowSetIterator("opIter");
if(iter == null)
iter = vo.createRowSetIterator("opIter");
iter.setRangeStart(0);
iter.setRangeSize(fetchedRowCount);
Row row = null;
for(int i = 0; i < fetchedRowCount; i++)
OperationSummaryVORowImpl operationsummaryvorowimpl = (OperationSummaryVORowImpl)iter.getRowAtRangeIndex(i);
Number opSeq = operationsummaryvorowimpl.getOperationSeqNum();
oapagecontext.writeDiagnostics(this, (new StringBuilder()).append("Inside operation Seq Value 2: ").append(opSeq.intValue()).toString(), 2);
float f = 0.0F;
if(opSeq != null)
f = opSeq.floatValue();
if(f <= 0.0F)
//throw new OAException("Enter Valid Operation Sequence Number. 0 is Invalid Operation Sequence",OAException.ERROR);
oapagecontext.writeDiagnostics(this, "Inside opseq equals 0", 2);
iter.closeRowSetIterator();
String s2 = oapagecontext.getParameter("evtSrcRowRef");
Serializable aserializable[] = {s2, "Summary"};
oaapplicationmodule.invokeMethod("handleOpEvent", aserializable);
oapagecontext.writeDiagnostics(this, (new StringBuilder()).append("Inside s2 : ").append(s2).toString(), 2);
Issue is, when ever i create new line and enter any value at operation seq, validation fires and new line is deleted.
Please let me know how i can fix this issue.
Thanks
Aswath

Hi Friends,
I solved it by myself.
if("handleOpSummaryEvent".equals(s))
OAApplicationModule oaapplicationmodule = pageContext.getApplicationModule(webBean);
String s2 = pageContext.getParameter("evtSrcRowRef");
OperationSummaryVORowImpl rowimpl = (OperationSummaryVORowImpl)oaapplicationmodule.findRowByRef(s2);
Number opSeq = ((OperationSummaryVORowImpl)(rowimpl)).getOperationSeqNum();
pageContext.writeDiagnostics(this, (new StringBuilder()).append("Inside row operation sequence: ").append(opSeq.intValue()).toString(), 2);
if (opSeq.intValue() == 0)
throw new OAException("Enter Valid Operation Sequence Number. 0 is Invalid Operation Sequence",OAException.ERROR);
Serializable aserializable[] = {s2, "Summary"};
oaapplicationmodule.invokeMethod("handleOpEvent", aserializable);
Thanks

Need help with error java.lang.IllegalArgumentException: timestamp on bar b

My company uses Java based applications for real time streaming stock market information and I have come across 2 users that are generating the same error:
Bar.addBar failed adding com.abwg.bar.BasicBar 20071210-08:27:00.000 104.34 104.35 104.25 104.25 950 to com.abwg.bar.BasicBar 20071210-09:30:00.000 104.11 104.38 104.11 104.38 436 :java.lang.IllegalArgumentException: timestamp on bar being combined older than original bar
I have had no luck trying to determine what the cause of this error is, however both users experience very laggy performance shortly after launching the application. I have not been able to duplicate the problem, and the developers have not been able to provide any response or possible causes yet.
I'd be very appreciative if anyone could help me make some sense of what this error type might mean. It's got something to do with the computer that the application is being run on. One user is on a Mac 10.3 using J2SE 1.4.2_12 and the other is on Win XP using Java 1.6_3

Thank you Frank and Carole for your response. The stated issue/error is resolved. It had to do with the upgrade somehow which lead to multiple certs for the same agent. Anyway, I had to delete ADS and all attached Agents, re-create ADS, re-create all Agents and re-register with the new ADS. I then manually re-registered the Directory Server instances on both the Primary and Secondary Servers with the new ADS. Voila, the DSCC Web console no longer prompts for server credentials.
But importing the Wild card cert issue still remains. I added the issuing CA chain to the ldap instance CA store and I see the certs listed. But when I try to import the P12 cert/key combo, I get an error which says something like: "The certificate is already in the database". But it is not, verified using certutil.
Yes internal CA or Self-signed Certs are fine. If I add the internal CA and Root CA to the cert store on my LDAP clients, then I am fine. No SSL errors. But want to avoid using such as we do have quite a few clients which would be connecting to the store. Hence want to use our enterprise wild card Cert. I am not sure if it is an issue importing a wild card pkcs12 format.
As mentioned above I did add the CA chain (which issued the wild card) to the actual instance, not the ADS. I can try that. But are you sure we need to add the Root CA to Tomcat ks.
And while we are at it, the Self-signed certs generated using the Console is only valid for 2 years. Is it possible to change the term ?
Thanks again.

Dear All,
The requirement is,
1. I need to add a field in Sales order.
Path for the same is as follows:
VA01> Goto> Header--> Accounting tab

a)create a new field. ex - zchdt (chq due date)
b)when customers enters value in Assignment,
i.e vbak-zuonr
after that trigger logic is
3.vabk-kunnr = knvv-kunnr
a)sy-date + knvv-kvgr2 (exclude sundays)
example - 14 sept + 30 days = 14th october
should populate value - 14th october i.e. field (zchdt)
4. This activity needs to be triggered before the sales order is saved.
kindly know whether this is possible or not.
if possible how & which exit & also with example code.
if you could give me your contact(cell no).

I want to attach more then 1 photo at a time like i can in IE do i need an add on?

I want to add more the one photo at a time in hotmail. I can do it in IE but wanted to know if i needed an add on to do it in forefox or change settings? if i do need an add on which one would be best?
Kind regards

Wich version of iPhoto do you have? You need iPhoto '09 or '11 to order prints.
Make an album of all photos you want to order in the same order.
Then select all photos at once, when you use Share > order prints.
You should see a panel like this, where you can mark the quantities. The screenshot is from iPhoto 9.6:

Hi,
I have created on windows service to fetch sharepoint list ad update the list items.
when i run this service in sharepoint server(where the sharepoint site is hosted),it is working fine. If i run the same service in another machine(sharepoint installed in this machine also). it is giving the below error

I have pointed .net framework to 3.5 version and target palform as Any CPU. Please suggest me

Hi mallela1,
I also had similar issue couple of months back when I was trying to access a remote URL from a Windows service when the site does not exists in the server where service resides.
You cannot access a remote url (even though it is SharePoint server and also in same network ) from server object model.
SPSite can look in the current server only. here what is happening is SPSite will look for this in the current server DB and it is not finding this errror.
So please dont use ServerObject model for accessing remote sites. You can use Client Object model for the code /requirement you have stated above.
I wasted lot of time in finding a work around to make to work. It did not. So look for other options.

Nandini

My HD is almost full. I need to add space. Can I use an external HD to continue using my startup disc as it is?

My HD is almost full. I need to add space. Can I use an external HD to continue using my startup disc as it is?
I create music and have run out of space. the message says 'your startup disc is almost full', and i just thought maybe buying an external hard drive and using it as the startup disc or whatever would do the trick. Does anyone know? Thanks!

External hard drives are relatively inexpensive...see some of those on OWC, www.macsales.com
You can use a large external drive to provide additional space by simply saving material to that volume instead of the startup disk. You can also partition the external drive to use part for Time Machine backups, and another partition for extended space. Or a third partition for a clone of the boot system made by Carbon Copy Cloner or SuperDuper, both free downloads, so should the internal drive have problems you could always boot from the external partition.
All of that can be done from Disk Utility.
Keep in mind that Mac OS X gets very unhappy when there is less than 15% of the startup disk space free.

In Top 10 with two dimension i need to add others in my MDX query

Hi this is code working fine and return top 2 product in a state. i need to add other sales also how can we do
with set FIPS as [Geography].[State-Province].[State-Province]
set TCat as
Generate( {FIPS}, CrossJoin( {[Geography].[State-Province].CurrentMember},
TOPCount(
         ([Product].[Subcategory].[Subcategory]),
         2,
         [Measures].[Sales Amount]
SELECT { [Measures].[Sales Amount] } ON COLUMNS,
TCat ON ROWS
FROM [Adventure Works]
hi fond one code it is work for one dimension only, i need for two dimension
WITH
SET [TCat] AS
TopCount([Product].[Subcategory].[Subcategory],10,[Measures].[Sales Amount])
MEMBER [Product].[Subcategory].[Other] AS
Aggregate([Product].[Subcategory].[Subcategory] - TCat)
SELECT { [Measures].[Sales Amount] } ON COLUMNS,
TCat + [Other] ON ROWS
FROM [Adventure Works]

Hi,
We will have to generate a set of tuples that includes both dimensions:
WITH
SET [Top2] AS
Generate
{[Customer].[State-Province].[State-Province].MEMBERS}
[Customer].[State-Province].CurrentMember
,TopCount
(EXISTING
[Product].[Subcategory].[Subcategory].MEMBERS)
,2
,[Measures].[Internet Sales Amount]
MEMBER [Product].[Subcategory].[All].[top2Aggr] AS
Aggregate((EXISTING [Top2]))
MEMBER [Product].[Subcategory].[All].[all Subcat] AS
[Product].[Subcategory].[All]
MEMBER [Product].[Subcategory].[All].[others] AS
Aggregate
(EXISTING
[Customer].[State-Province].CurrentMember
,[Product].[Subcategory].[Subcategory].MEMBERS
[Top2])
SELECT
{[Measures].[Internet Sales Amount]} ON COLUMNS
[Customer].[State-Province].[State-Province].MEMBERS
[Product].[Subcategory].[top2Aggr]
,[Product].[Subcategory].[others]
,[Product].[Subcategory].[all Subcat]
} ON ROWS
FROM [Adventure Works];
If you plan to tweek this solution, you may want to align the dimensionality of the [all Subcat] member with the others members by changing its definition:
MEMBER [Product].[Subcategory].[All].[all Subcat] AS
aggregate(EXISTING
[Customer].[State-Province].CurrentMember
,[Product].[Subcategory].[All]
The former defintion also works in our case because it's a singleton set and it is put in a tuple when crossjoined with the axis 1 giving it the right dimensionality.

Need to add new cameras to Camera Raw in PS CS2 (not ready to update to CS6 yet). Can do... how?

Windows Vista-64, CS2 Photoshop and Illustrator. CS2 works well for what I do... don't need to update yet. Need to add Canon 5D Mark2. When try to open Raw files, get error message: Photoshop says it can't complete the request because it isn't the right kind of document. I believe this means that the camera is not recognized. Current DNG Converter is 3.7. Would like to add Raw support for all newer cameras, so able to work with files from virtually any customer.

I use camera raw to make preliminary color/brightness/contrast adjustments then save as 16-bit RGB file... then final adjustments in Photoshop. If I can add (for example) DNG Converter 8.2, to simply allow the CR2 image to open, then I don't need any other features. What I gain be upgrading to CS6 is additional functionality in Photoshop... no doubt I will be very glad when I do, but meanwhile I only need camera raw as a preliminary step in my workflow.
Not brain surgery... whatever additional functionality is available in Canon 5d mark 2 that is not in Canon 5d is unnecessary for my purposes now. Is there a reason that Adobe would not allow adding 5d mk2 (even if not all functionality is enabled)?
Ideally, I would hope to download DNG Converter 8.2, install it in my Photoshop CS2, and continue with my normal workflow process. Adobe could easily create a warning that "some functionality provided in certain newer camera files is not available, recommend upgrading to CS6." Just makes sense to support users as long as possible rather than force the upgrade.

I need to add a skin to my .fla or .swf, how can I do this without converting?

I have created a project using motion and sound. I need to add a skin to it which you use to be able to do when you published it. Now it seems the only way to do it is by exporting my file into Media encoder then convert it to a MP4 ( there is no F4V or FLV in Media encoder, that I can see). When I export this my sound quality is lost. Then when I re-import into Flash to add the skin I lose the sound all together. What am I doing wrong?
Thanks

I'm guessing you're using the free version. I would first try to import a table from another PDF file. If that doesn't work I would try using the "add item" feature for either the "text" or "email" fields because those are formatted as 2 columns. You will just have to manipulate them how you want them.
Good luck!
