Can code snippet below be rewritten in a better way

Hi
I have written a simple code snippet I feel there has be other ways in which this code could be improved upon. Any assistance in this regard is highly appreciated
the code is as below:
if (obj instanceof Foo1 ||
    obj instanceof Foo2 ||
    obj instanceof Foo3 ||
    obj instanceof Foo4 ||
    obj instanceof Foo5 ||
    obj instanceof Foo6) {
// do something
}thanks in advance

Yes. Move the functionality in question into the various Foo* objects, using the same method name each time.
If the implementation is the same over groups of Foo* objects, then use inheritance of composition to share it. (for example if Foo1 - Foo6 would share that same block of code, but Foo7-Foo12 do something else).
If there are only those six Foo* classes, why are you checking?

Why can't I paste code snippets in Page Properties Metadata area for head ?

I downloaded the new Muse 2014 CC the other day and everything seemed to install correctly, however, yesterday I tried add Google Analytics code snippet to the Page Properties >> Metadata section where code goes into <head> area of the site and after coping the code, in Muse Paste was grayed out. I tried on both the HOME page and Master page.

How can I do a screenshot when my cursor needs to be in the EDIT >> PASTE drop down? It's impossible. Just know that after I click into the <head> code area and select it so that it becomes outlined in blue, then go to EDIT >> PASTE none of the items in the EDIT drop-down are available, everything is grayed out.

com.ibm.idmg.ssl.sslProvider=com.sun.net.ssl.internal.ssl.Provider
#     Specify the keystore file that this ssl socket should use
com.ibm.idmg.ssl.keyStore=server.ks
#     Specify the password for this keystore file
com.ibm.idmg.ssl.keyStorePassword=servercanpass
#     Specify the password used to protect the keys in the keystore
#     Note: all the keys should have the same password
com.ibm.idmg.ssl.keyPassword=icanpass
The client properties file
#     Specify the SSL provider here.
#     Using sun's reference implementation for testing..
com.ibm.idmg.ssl.sslProvider=com.sun.net.ssl.internal.ssl.Provider
#     Specify the keystore file that this ssl socket should use
com.ibm.idmg.ssl.keyStore=client.ks
#     Specify the password for this keystore file
com.ibm.idmg.ssl.keyStorePassword=clientshouldpass
#     Specify the password used to protect the keys in the keystore
#     Note: all the keys should have the same password
com.ibm.idmg.ssl.keyPassword=canipass
Now to create the certificates..
Its a 5 step process
1) Create the keystore file.
     keytool -genkey -alias mohan -dname "CN=Mohan Tera OU=IS O=IM L=sanjose S=NY C=US" -keystore server.ks -storepass servercanpass -validity 180 -keypass icanpass
2) Create a self signed certificate. If you need to get it signed from
     verisign then you have to create a certificate request. For testing purposes,
     you can create a self signed certificate.
     keytool -selfcert -alias mohan -dname "CN=Mohan Tera OU=IS O=IM L=sanjose S=NY C=US" -keystore server.ks -storepass servercanpass -validity 180 -keypass icanpass
3) Export the public key from the keystore to a certificate file that is to be imported to the client keystore.
     keytool -export -alias mohan -file fromserver.cer -keystore server.ks -storepass servercanpass
4) Repeat the above steps for the client also..
     a)
     keytool -genkey -alias moks -dname "CN=Jennifer Poda OU=Javasoft O=Sun L=Edison S=NJ C=US" -keystore client.ks -storepass clientshouldpass -validity 180 -keypass canipass
     b)
     keytool -selfcert -alias moks -dname "CN=Jennifer Poda OU=Javasoft O=Sun L=Edison S=NJ C=US" -keystore client.ks -storepass clientshouldpass -validity 180 -keypass canipass
     c)
     keytool -export -alias moks -file fromclient.cer -keystore client.ks -storepass clientshouldpass
5) Import the certificates that were exported in steps 3 and 4c in client and server keystore respectively.
     keytool -import -trustcacerts -alias new -file fromserver.cer -keypass keypass -storepass clientshouldpass -keystore client.ks
     keytool -import -trustcacerts -alias new -file fromclient.cer -keypass keypass -storepass servercanpass -keystore server.ks
And voila you are all set to go..
Hope this explains to all the people who are struggling with JSSE..

Moks

Can a JOIN statement be rewritten using FOR ALL ENTRIES in any case ?

I had a SELECT statement, like:
    select p~key1 t~col3 t~col4 p~col2 p~col3
      into table itab1
      from ( table1 as p left outer join table2 as t
              on p~key1 = t~key1 and t~col2 = someValue ).
Among which, table1 and table2 are fully buffered.
Code Inspector suggests that this statement should be, e.g., rewritten using FOR ALL ENTRIES.
Since FOR ALL ENTRIES is only possible for WHERE conditions of the SELECT statement, which means the internal table right after it is not available for the RESULT clause of the SELECT statement, can the above statement be rewritten? If yes, how?
Thanks!

hi ,
select pkey1 tcol3 tcol4 pcol2 p~col3
      into table itab1
      from ( table1 as p left outer join table2 as t
              on pkey1 = tkey1 and t~col2 = someValue ).
<i>look below code</i>
select * from table2 into table int_tab2 where col2 = someValue.
select key1 col2 col3 into table int_tab1
FOR ALL ENTRIES IN int_tab2
WHERE key = int_tab2-key1.
then use read statements for manipulations

Also, please see the code below, the getInfo() method is not taking care of Type safety right??!!!!

Code snippet for custom scheduler

Hi,
I need to write a custom scheduler as per one of the solutions present in doc in metalink (doc id:1109539.1). Few lines of information in the doc is as below:
A better solution is to:
1. Create a custom scheduled task.
2. The task should run every 10 minutes, and should do a simple call to the server using the singleton instance.
3. This will assure that the instance is kept alive, hence it will not timeout.
As per the above solution, what exactly is meant by "do a simple call to the server using the singleton instance". Does anyone help me to provide a code snippet to do the same.
Thanks
DPK

That Metalink ID is not related to your requirement.
It is a workaround if someone is using Singleton Pattern in their code.
If they are using Singleton then session will expire after some time and it throws error that's why they are suggesting to use that instance by creating a schedule task after every 10 min so that instance should be alive. It's no where related to your use case. Don't use Singleton Pattern in your code.
You can read here about Singleton

How do I create a drop down menu with Code Snippets and Flash CS5?

Hi
I am wondering how to create a drop down menu using the Code Snippets and CS5?
There are some older tutorials out there and it would be nice if someone could create an updated drop down menu tutorial, and it might be me doing this after I have figured out the best and easiest way to create one, but before that I need some pointers.
Thanks!
Have a great day!

You can use panel widget to create manual menu where set to show target on rollover.

OLE2 Doc/Code snippet to assist in creating a word doc with underlined text

I would like to use OLE2 to create a simple Word document. I would like some of the text to be bold/underlined and the rest of the text to be regular. There seems to be a serious dearth of information regarding OLE2 in conjunction with PS/SQL in Word applications. We're running Forms 6 and Oracle 9i.
I don't believe that I need to use the techniques described in the Forms Manual (OLE2 containers, etc.). I have managed to create a Word doc and write some text to it but I've been unable to find out/guess at the syntax that I'd need to control bolding and underlining. It would be a big help if I could just find the syntax for Word OLE2 commands. During my documentation search, I seem to remember a post that mentioned 'Reference 2' and maybe 'Reference 3' as a source of information related to OLE2 in PL/SQL code. If anyone can give me a shove in the right direction I'm more than willing to read the manuals. I won't be too disappointed if someone could send me a code snippet either!
Thanks,
Ron Walker

Hi Ron,
Office ships with a number of resources that you will find indispensable for the sort of work you're doing. Take a look at the VBA IDE (Visual Basic for Applications IDE). You may already be familiar with it, if you've ever written a Word macro, but to call it a macro editor sells it short -- it is a full-blown development environment. Its Object Browser allows you to browse Word's object model, search by keyword, and view call syntax.
In case you aren't familiar with the VBA IDE, try this:
1. Open Word
2. Switch between Word and the VBA IDE by pressing <Alt><F11>
3. Open the Object Browser by pressing <F2>
Spend some time familiarizing yourself with the Object Browser. Constrain its scope by selecting the Word library instead of <All Libraries> (the default). Learn to search by keyword. Click on items within your results for details. If Visual Basic Help is installed, pressing <F1> will raise help on a selected item.
Visual Basic Help may not be part of the Compact or Typical install. Running Office Setup, either from the install CD, or through Add/Remove Programs under Control Panel, will allow you to add the feature. (The Office installer lists Visual Basic Help in the Office Tools section.)
I have found the VBA IDE to be the perfect place for prototyping and testing automated processes. It is a far friendlier environment for learning Office automation, as it offers code completion and context-driven help. Once the process works, I manually translate my VBA routine into Forms PL/SQL, which is fairly painless. I've written a short tutorial, that I will post shortly -- I didn't want to bury it in this thread!
Hope this helps,

EDGE ANIMATE CC (2014) : Missing Code Snippets sidebar - WHY!?!?!

I just updated today, and now a project I had been working on for weeks (my first real project) won't open in CC anymore. The only reason I wanted to open it back up in CC - NOT Adobe Edge Animate CC (2014), was because this updated Edge Animate IS MISSING THE CODE SNIPPET SIDEBAR!! WHY!! WHY!! WHY!! It's a little hard to follow along with tutorials you have been using when they insert snippets from the sidebar and suddenly you don't have one anymore!
I have rebuilt permissions and restarted hoping that would fix the issue but it has not. If I can't get this project to pen in CC, can someone tell me how to trick CC into opening it again? Byt he Way -- the old version of Edge Animate was AUTOMATICALLY UNINSTALLED with this update. Also very frustrating!! I had to go to my could menu and download CC (3.0) again.

OK - Possibly Good News... I talked to Adobe Tech Support. I am able to download a previous version of the Edge Animate CC by choosing PREVIOUS VERSION under the FIND NEW APPS section of the Creative Cloud Desktop app. This is a new feature of CC. Thankfully. I can install CC and then do as hemanth kumar r suggested and edit the _edge.js file to allow 3.0 to open the file.
Thanks for all of the help. Sorry for the frustration in MY TYPING . I'll reply if that all works.

Jdev10.1.3 - is there a suppotr for parametrized code snippets?

Hi,
I am looking to add parameters to the code snippet (simple name value pairs and iterators)
I need to be able to prompt the user to enter these parameters when designing the page (inserting the code snippet results in an editor that prompts for the parameters)
Is such a feature available or planned?
thanks
Vijay

Hi,
depends on what kind of code snippet you need. JDeveloper supports code templates that can have variables in them that are filled in by the developer when adding it with <abbreviation>ctrlenter
See tools --> Preferences --> Code Editor -> Code Templates
If e.g. you create a code template "about" and add the following snippet
* File: $file$
* Date created: $date$
* Author: $author$
then all variables surrounded by $..$ are highlighted (you can have JDeveloper to add default values as well

No way to add code snippets to the palette in 11g

Hello,
According to the Help Center, I should be able to add "codes snippets" to my palette, like I used in 10g...
Adding a Code Snippet to the Palette
You can add pages to the Component Palette to group your snippets, or you can add snippets to the existing Code Snippets page. Once you add snippets to the Palette, you can insert this code into any file you have open in the source editor by selecting the snippet from the Palette
within the Configure Component Palette dialog. In the Configure Component Palette dialog, for Page Type select snippet to view only those pages containing snippets.
Well , in the Page Type drop list , I only see "java" and "use case" ?
I am running J2EE Edition Version 11.1.1.0.1 Build JDEVADF_MAIN.BOXER_GENERIC_081203.1854.5188
Any thoughts ?
Cheers

If all you want is code snippet why not use the code template feature?
It is more dynamic and will allow you to use variables that you can switch - then you can just use the keyboard to get the value.

          COH_MANAGED_BOX_EXTRACTOR(Integer32::View, CacheD3Context, getState);
     ExtractorProcessor::Handle vStateFetcher = ExtractorProcessor::create(vStateExtractor);
     Integer32::View vState;// = _cache->invoke(vKey, vStateFetcher);
     return *vState;
Essentially I have CacheD3Context object but I don't want to read back the whole object just the state field.
I have been told that something called a 'ReducerAggregator' is a better way of doing this but I haven't been able to find this yet.
Thanks
Joe

Hi Joe,
The invoke method returns an Object::Holder, which will need to be cast to the extracted type:
int CacheD3ContextRepository::getD3ContextState(int call_id) const
    Integer32::View              vKey            = Integer32::create(call_id);
    ValueExtractor::View         vStateExtractor = COH_MANAGED_BOX_EXTRACTOR(Integer32::View, CacheD3Context, getState);
    ExtractorProcessor::Handle   vStateFetcher   = ExtractorProcessor::create(vStateExtractor);
    Integer32::View              vState          = cast<Integer32::View>(_cache->invoke(vKey, vStateFetcher));
    return *vState;
    }Note that when the extraction will be performed server side, the above extractor will be evaluated as a ReflectionExtractor in java, and will invoke the java getState method. This implies you'll need the CacheD3Context (or equivalent) java class in the classpath of your cache servers. If this is not an option then have a look at PofExtractor.
thanks,

Can code snippet below be rewritten in a better way
