HTMLEditorKit : How you handle FRAMES, IFRAMES and JAVASCRIPT
Hi all,
Currently im using the HTMLEditorKit to parse through the HTML page. Obviously its easier when the elements are on the body of the page. But what if the page has frames,iframes or javascript and i want to extract links that these elements reference to. How do i do it? I know some of you would recommend my class to extend the parsercallback class. But is there a way for example i can use 3 or even 4 different iterators each pointing to the different elements ?
and lets say if i reference to a SCRIPT tag of the HTML, how do i extract the possible URLs in it. Same goes for iFrames and JavaScripts. Can anyone please help me with this ?
Tim,
The form action needs to be the page URL. The INPUT fields/objects of your form will be sent as parameters when the form is submitted. These parameters can be read by your portlet by using the parameter passing PDK services. It is recommended to use qualified parameters in case the portlet that reads the parameters is the same as the one that has submitted them.
As far as I remember the parameter passing sample portlet contains similar code to what you're looking for.

In BDC how you handled header data and item data
Raja,
Can you be more clear ?
Usually you load the header data one and then loop at the item data and then load the item data.
This example should help you.

How to Handle the lower and upper case in 'POPUP_GET_VALUES'
Hi All
i am using the following FM and when i enter value on the
popup in lower case or with capital letters i see the field
with upper case ,this is problem for me since i need to
take the field and compare it ,there is a way to handle this
issue ?
CALL FUNCTION 'POPUP_GET_VALUES' "#EC FB_RC
EXPORTING
popup_title = lv_head_msg
IMPORTING
returncode = lv_rc " User response
TABLES
fields = lt_field " Table fields, values and attributes
EXCEPTIONS
error_in_fields = 1
OTHERS = 2.
Best regards
AlexHi Alex,
This because, the field and table name that You are passing in lt_field, has a conversion attached to it, which causes the converison in case.
For e.g. If You pass MARA-MATNR and try to get the values from pop-up, the value will get converted to upper case, but if You pass MAKT-MAKTX (which does not have a converison attached to it), the value will be retrieved as it was entered. This is standard SAP, which is correct.
If You need to get values of any text field, pass any SAP text field as reference in your table lt_field. Hope this helps...

How to handle monster fact and monster diamension in obiee
Hi,
what are ways to handle handle monster fact and monster diamension in obiee 10g.
ThanksHi,
Thanks for your reply, I was trying things suggested, I found that the actual physical SQL (which I can get from "Manage Session" link) run in like 4-5 seconds in Query analyzer but: when I studied SQL carefully it does not contain some fiters which we I have applied in report.
From example i have a filter in report <Measure.Present = 1 > but in Physical SQL i cannot see that filter. However, the results it gives on dashboard are correct that is after it applies the fillter.
Any idea why is this happening?
My guess is because above filter is not being applied at physical sql level thats why query fetches like 20000 recors in server cache and then it applies <Measure.Present = 1 >. Thats why it might be taking time ?
Please give me your suggestions.
Thanks ! -
This is how you extract frames from video
right then, in answer to many posts about how to get the individual frames from video, here is my solution. it seems to work with mpg files but it doesnt seem to work with any of the avi files i tried. not sure why it doesnt work with those. i have modified javas frame access.
nothing is displayed except it prints which frame it is doing.
if anyone wants to improve it, please do. i still dont understand fully how it works so i probably wont be able to answer many questions about it. anyway here it is:

private Dimension size;The quality of the produced video from this example is very poor.
It comes to huuuuge surprise the following fact.
If you comment the line where you set the PostAccessCodec, the chain of the codecs is:
MPEG-1 decoder -> YUV2RGB -> Direct Draw Renderer. ( The one used from the system to decode and render)
If you run the example purely as is above you get the following sequence(as long with the poor quality):
MPEG-1 decoder -> YUV2RGB -> Windows GDI Renderer.
So you say lets set another Renderer. So
you add the following line videoTracker.setRenderer( new DDRenderer() )
What comes to a surprise is the following chain of codecs:
MPEG-1 decoder -> YUV2RGB -> Post Codec -> Java RGB Converter - > DDRenderer
The quality now may be perfect but video runs to slow. The surprising thing here is that even though we have set the outputFormat of the PostAccessFrame codec to RGBFormat the system converts it again to RGB through codec Java RGB Format.
After searching a lot and reaching the conclusion that the deference between the 2 RGB's is their sizes I sudently was brought in front of a method called grabFrame(). Bels started ringing inside my head. Starts were comming up. Looking at the definition of the class com.sun.media.renderer.video.DDRenderer I descovered that this damn class implements the FrameGrabbingControl Interface. What the f.....? The problem that consumed 4 days of my life and multiplied with 10 to give hours has finally come to an and.
Summing up the solution for grabbing frames is this!!!!!
DDRenderer renderer = new DDRenderer();
videoTrack.setRenderer( renderer );
and in your actionPerformed implementation
FrameGrabbingControl fr = (FrameGrabbingControl)renderer.getControl( "javax.media.control.FrameGrabbingControl");
Buffer frame = fr.grabFrame();
The following stuff ...are stated in FrameAccess

Hai all,
Once agian i am here to share my doubts with u ppl,I am currently working on BSP application using frames.
i have a parent document which contains top frame and bottom frame.my top frame contains menubar wher i can select my choice.based on my selection bottom frame should get refreshed with the desired content.this will work fine with pages with flow logic.but using mvc i am little bit confused to get the desired output.the thing is when i perform some actions in my bottom frame my control should go back to parent window(contains two frames) that page should deside which one should display in bottom frame... how can we perform this..?
does anyone worked on this ..?if so, plz share ur knowledge with me
leoiz.Hi,
read the answer from Rainer first then take a look at this view:
<phtmlb:matrix>
<phtmlb:matrixCell design = "PADLESS"
row = "1" />
<bsp:call url = "left.do"
comp_id = "left" />
<phtmlb:matrixCell design = "PADLESS"
row = "1" />
<phtmlb:matrix>
<phtmlb:matrixCell design = "PADLESS"
row = "1" />
<bsp:call url = "header.do"
comp_id = "menu" />
<phtmlb:matrixCell design = "PADLESS"
row = "2" />
<bsp:call url = "body.do"
comp_id = "body" />
<phtmlb:matrixCell design = "PADLESS"
row = "3" />
<bsp:call url = "footer.do"
comp_id = "footer" />
</phtmlb:matrix>
</phtmlb:matrix>
This is an example how your default.htm view could look like. When you need automate scrolling take a look at this extension <xhtmlb:overflowContainer> perhaps it can help you.

Jdev 10.1.2 UIX: How to handle page event and also follow link destination
Hello guys, I think this should be easy:
I have a frame with a link that produces an event which is handled by an event handler. But this link also has destination and targetFrame attributes.
The event handling just updates the visual state of the frame which contains the link, but I also need the link to load the destination into the targetFrame, but this is not happening, just the event is handled but the link doesn't work.
How can I get both, the event handling and the destination, work?
Here is the code for the link:
<link text="${uix.current.title}" destination="${uix.current.destination}"
targetFrame="main">
<primaryClientAction>
<fireAction event="optionClick">
<parameters>
<parameter key="clickedIndex" value="${uix.current.index}" />
</parameters>
</fireAction>
</primaryClientAction>
</link>Thanks
FerThanks to everyone who read it. I figured out how to solve this.
The workaround was to set every link destination to one action which performs 2 things:
1. Update the visual state of the first frame (setting attributes to a session object) and;
2. Puts the destination that I wanted to be loaded into the second frame as a request attribute;
besides all the above, the link had its targetFrame set to "_parent", so the Frameset page was reloaded and therefore reloaded both frames, this way the first frame renders updated (thanks to the changes made to the session object) and the second frame has its source attribute bound to ${requestScope.frameDestination} to load the desired page (actually a struts action).
Hope this helps someone else.

How you handle your signatures
What are you doing with your signatures which fire and are false positives? Are you using event action filters or are you disabling the signature? In some cases I see where disabling that signature would be fine. Like if you have a DNS box which is patched and not susceptible to a exploit being noticed by IPS - Since your system is patched and no other boxes are susceptible to the exploit then it seems only logical to disable the signature, yes? But event action filters come into place for signatures like sig-3030 which, in most cases, should only fire when the source is from outside your network. Just want to make sure Im on the right track. Anyone know of a good site which discusses IPS best practice, administration and policy?
Also how many of ya'll monitor your internal network?
ThanksWhen I'm troubleshooting a new alert I usually enable 'log pair packets' so I can put more context around the alert itself. Although they get correlated in MARS I use CSM to tune the sensors and signatures. I'll cross-launch to IDM to pull down the packet captures, saving them with somewhat descriptive names in case I need to revisit them later. I also use a great netflow reporting engine (mazu networks) to see where else the suspect PC has been going, and then use online tools like dnsstuff.com, spamhaus DROP lists, Dshield, to see if the IP address is on any block lists. This tool (as well as Arbor Networks, Lancope, etc) also do their own non-signature-based network behavior analysis, and sometimes (not always) something with correlate here too.
After I get enough information I try to tune the actions on the sensor itself. Sometimes you have to fall back on a MARS drop rule, just to screen out false positives or handle special cases, but I think its better to keep the alert from occuring in the first place. Having too many filters gets ugly fast.
You should also be leveraging Cisco's Intellishield service ; each IPS sig subscription gives you (free) access to detailed information on the IPS sigs and the vulnerabilities that prompted the sig in the first place. Great service. I've been able to disable a bunch of sigs using this alone.
Good luck. -
How to handle multiple updates and creates sequentially
Hi All,
I have a requirement where multiple updates and creates will happen on an Order (say Purchase Order). I need to capture all these updates/creates and synchronize the other system in real time. In other words, as soon an order is updated/created in EBS, the same needs to be reflected in other system database.
I have thought of using a JMS queue that'll store all the incoming creates/updates and a BPEL process will keep polling this queue. But in this case how do I ensure the sequence in which the new instances will be created. e.g. create order message was picked first from the queue and an instance got created. While this instance was in execution, another update happened on the same order for which another instance got created. Now before the first instance could get completed and created an order, second instance is trying to update the custom database because of which it would fail. How to restrict second instance from running before the completion of the first one?
I have also thought of capturing Order Update/Create business events from EBS but there also the same problem. Instance created by Update event can try to do the update before the instance created by Order Create could create a new order.
Any method to solve this.
Any pointers/suggestions/approaches are more than welcome.

DBMS_FGA.add_policy .. How to handle multiple tables and multiple users
Dear All,
My database is 11gR1 and Linux is the platform.
I have more then 50 very important tables and around 15 database users.
I want to implement fine grained auditing on these important tables.
This is how I am going to implement it:
SQL>BEGIN
DBMS_FGA.add_policy(
object_schema => 'Scott',
object_name => 'SAL',
policy_name => 'SALARY_CHK_AUDIT',
audit_condition => NULL,
handler_schema => 'imran',
statement_types => 'SELECT,INSERT,UPDATE,DELETE',
audit_column => NULL);
END;
what is i have to pass multiple tables in object_schema and multiple users in handler_schema.
I hope i am able to clear my question, any doubts please let me know.
Regards, ImranHi,
object_schema - The schema of the object to be audited. (If NULL, the current log-on user schema is assumed.)
in case if you like to audit for multiple users - then try to test by holding a null value and test access the important tables -where the relevant auditing records are generated as per your requirement or not. i have not tested.. try it

How to handle when Client and server write to the socket at the same time
Hi all,
I'm writing a socket communication when client and server may write information the the socket at the same time. I look every where but the samples from the internet only shows example of server replies to client after receiving requests from clients.
Let's say that:
Client 1 ->Socket 1 -> Server 1
Now if there are two threads in the server, one blocked waiting for the input from client on socket 1, the second one write something on the socket to client 1, is it possible?
And if it's possible, if at the time Server 1 writes information to Client 1, Client 1 writes some information to Server 1 too, will there be any conflict problem or the socket could handle that two ways communication simultaneously?
It's critical questions for me. Thanks for your help.I really use Server Client paradigm. However, beside the request, response mechanism, there is also an additional mechanism called update which server periodically send information update to client without the need for a request from client.
So you suggest client should initiate 2 sockets, one for request and response, one for receiving update from the server? Will this work? -
How to handling Binary data and File operation?
Hello Everyone,
I think this question might have been asked a lot of time but I was unable to find one solution so, please help needed in this from all you guys..
I am creating a byte[] of the media files of mp4, and jpg, using the below code,,
File ff = new File(filename);
fos = new FileOutputStream(ff);
int b;
byte[] f = this.getMediaFile();
for (b = 0; b < f.length; b++) {
if (f[b] != -1) {
fos.write(f);
fos.flush();
fos.close();
After i convert it i have to store it in the MySql Database as BLOB object, for retrieving byte[] from the database is simple i can do that also successfully with this code.java.sq.Blob obj = (java.sql.Blob) rs.getBlob("file");
InputStream is = null;
ByteArrayOutputStream bc = null;
is = obj.getBinaryStream();
bc = new ByteArrayOutputStream();
int b;
while ((b = is.read()) != -1) {
System.out.print(b + " ");
bc.write(b);
Now the real problem is that when i want to recreate a mp4 audio or video file i am unable to do so, the file created is smaller in size and also it doesn't get played in windows default player nor VLC. I am able to get the image file of jpg format using the BufferedImage & ImageIO.writer();
How do i do for mp4 file, have no clue for that.
Pleases help out with this.
Thanks..if (f[b] != -1) {I don't get that line. What if you try to output the data without that condition, like this:
fos = new FileOutputStream(ff);
byte[] f = this.getMediaFile();
for (int b = 0; b < f.length; b++) {
fos.write(f);
fos.close(); -

How to Handle Large Dumps and Complex Calculations in OBIEE
Hi,
We are working on some reports in OBIEE and we are unable to optimize performace. Please consider following scenerios:
1) Detail Report
In this particular report we have essentaily data dump. That is there are 5 Dimentions and a Fact table and we are just selecting
fields from various Dimentions and facts. But the problem is there are over 5000 records. I guess that is making report very slow.
Another issue is when we click on PAGE Contols, they simply dont work, that is if we click on (>>) to see all records its takes lots
of time but show only first 25 records. Any idea what is the problem.
2) Calculated Report
We have one calculated report where there are 7 calculated columns. Because every column contains different Measures and we have to
use lots of Filter expressions
Eg: Filter (Measure1 USING {@VarDate} BETWEEN DIM1.FromDate and Dim1.Todate AND {@VarDate} BETWEEN DIM2.FromDate and Dim2.Todate AND <SOME OTHER FILTERS> )
The Granuality of data is at employee level and there are around 1388726 records in Fact table.
Is there is any way to optimize above except to create a summary table instead?
kindly guide us on above sceneriosHi,
Thanks for your reply, I was trying things suggested, I found that the actual physical SQL (which I can get from "Manage Session" link) run in like 4-5 seconds in Query analyzer but: when I studied SQL carefully it does not contain some fiters which we I have applied in report.
From example i have a filter in report <Measure.Present = 1 > but in Physical SQL i cannot see that filter. However, the results it gives on dashboard are correct that is after it applies the fillter.
Any idea why is this happening?
My guess is because above filter is not being applied at physical sql level thats why query fetches like 20000 recors in server cache and then it applies <Measure.Present = 1 >. Thats why it might be taking time ?
Please give me your suggestions.
Thanks !
