How much of Java is involved

1.How much of Java is involved in Oracle Portal. If someone wants to just use the functionality available out of box from Oracle Portal, does it involve any use of Java.
2.Can someone give an example of extending the functinality of Oracle portel using Java and XML.
3.How much of Java knowledge and skill level is requried to start working or learning Oracle Portal.
Thanks

The use of Java for extending Oracle Portal with portlets is optional. You can build portlets via Java programming, but you can also build them without Java programming, for example, Web Clipping, PL/SQL, Omniportlet, and Portlet Builder require no Java knowledge. The OracleAS Portal Developer's Guide has an excellent chapter on choosing which technology to use for building portlets. It considers such factors as whether you know Java in helping you decide what to use.

How much XML/Java does one have to know?

I'm new to OA and I have a question. Besides Oracle and PL/SQL how much XML/Jave does one need to know in order to pick up this product. Does it get in your way if you don't know either? Can you get by with out it?
In other words where is that knowledge inportant?

I think this thread has been discussed so many times on this forum, always search old threads before raising new! One need core java knowledge along with pl/sql to start with OAF.
You definately don't need knowledge of xml here as it is generated automatically by Jdeveloper. If you have some knowledge of j2ee design pattern , it would be an added advantage, but basic knowledge of core java is sufficient to start with OAF.

How to run Java application involving DOM3 in a command shell?

Dear all,
I am currently in a testing phase on my Java implementation (in JBuilder 2005) utilizing DOM3(built 2 .jar files from Ant via CVS thanks to dmbdmb). It seems working properly. To experiment its capability of handling big size files, it is essential to do a bit testing by running the application in a command shell (got 'OutOfMemoryError: Java heap size' when run it in JBuilder), something like:
Java -Xmx256m MainHowever it gives out another error of
java.lang.NoSuchMethodError: org.w3c.dom.Node.setUserData(Ljava/lang/String;
Ljava/lang/Object;Lorg/w3c/dom/UserDataHandler;)Ljava/lang/Object;All fine in JBuilder because I configured its 'required libraries' and added up the 2 DOM3 .jar files. Now how should I do to make them working in a command line? I already added the paths of these 2 .jar files to CLASSPATH and also tried to put a copy of them under the same directory as 'Main'. Unfortunately the 'NoSuchMethodError' is not going away...
Thanks to any help

I managed to include these 2 DOM3 jar files into a jar file, xml.jar, together with all other class files. (I put a copy of these 2 DOM3 .jar files and the JDBC connector file, mysql-connector-java-2.0.14-bin.jar into the same folder as with other class files, then run something in the command line like:
D:\>jar cmf manifest.mf xml.jar xmltree/*   //xmltree is the folder/also the package nameThe resulting xml.jar can use the included 2 DOM3 jar files, however another JDBC error occurs when attempting getting a connection to MySQL( details also on http://forum.java.sun.com/thread.jspa?threadID=642812 ). Why do these jar files behave differently, as 2 DOM3 files do well in the xml.jar, whilst the JDBC connector jar does not like it?
Another anomaly is that, though they work well by double clicking xml.jar, the 2 DOM3 jar files still do nothing if executing the jar from a command line as follows:
D:\>java -jar xml.jar      //it still throws out NoSuchMethodError
Why the DOM3 jar files also behave differently depending on how the xml.jar is invoked??
Really cannot work it out & thus need your kind help!

How to solve Java problems involving playing videos on firefox. Please see the details of this question.

When I play videos (YouTube, Novamov, Videobb, etc...) I get a message from Java saying: " video format unidentified/unknown" and the video's picture start stopping and playing (frame by frame) while voice has no problem. What should I do? I've already reinstalled Java on my laptop but that didn't solve the problem. Thanks a lot!!!

Has anybody noticed how much RAM Java uses?

Hi Everyone,
I have been playing around a little with Java programs, and far out the RAM in my computer gets strained!!! I don't know how many times a Java application has completely locked down my 667MHz, 320Mb computer. My brothers 1.2GHz, 256Mb runs Java a little better, but really to play "hard ball" Java style you would need a 2.4GHz Pentium 4 with between 512 and 1024MB of RAM.
Obviously Sun Microsystems have looked to the future with Java. They have played their cards very well by creating a programming language that is a little hard for current computer hardware to run.
In ten years time when we are talking about computer hardware, we will have hard drives with terabytes of space sitting on our home PC, don't worry about clock speeds, there won't be any, the Quantum computer has already taken care of that (for all those novice Quantum Guru's out there - information exchange takes place in no time, that is not faster than the speed of light... the messages simply takes place in no Time.). Technology moves so fast that it is hard to keep pace, unless of course you are addicted to Reading!!
At the moment we obviously do not have the hardware to run massive Java applications. So instead we have garbage collection. How effective is garbage collection, and what can be done to improve it?
I have read a little about garbage collection, but it sounds quite haphazard, possibly unreliable. Obviously object orientated code takes up a lot of memory, by learning garbage collection techniques I hope to improve my coding. If anybody who reads this thread can contribute anything of personal experience related to garbage collection, it will be greatly appreciated. Code is always good, but I am also looking for peoples ideas about improving garbage collection, even if those ideas are not viable in the current version of the JDK.
Thanks for your comments and I hope that you enjoyed reading this thread.
David

Hi,
if it was meant as a joke, I enjoyed it - but if your opinion is really that of java, you have posted, I would suggest to read some of the documentations provided by Sun and you will find out, how java uses memory and you will also find out, that garbage collection is not the point, you have to worry about, because it is automatically done by the JVM. Also javac has parameters, where you can manipulate the memory usage of the JVM. So, please start reading in the case this was not just a joke :)

J2ME to personal Java, how much need to change

I have an appilication that is written in J2ME. Now i'd like to experiment how it runs on PersonalJava devices, such as Nokia Communicator.
How much I need to change. The app is small pop-mail program, that fetches emails from my mail server. It uses HttpConnection. The Gui is build with few Form.
Am I right when I assume that just the GUI parts have to be re-written (using AWT), mostly all the rest works. If I compile existing code with Jdk 1.1, are the errors I get the changes I need to do... Or is there something else too ?
Thanks in advance,
P_trig

The Idea was not to test the app on Desktop, but to convert it to PersonalJava and I wondered how much there is to change before J2ME app runs in PersonalJave Device.
My app runs fine, I know that already, but I need to make another version of it for PersonalJava. IE, which elements of current versions have to be rewritten, that's my question, not how to emulate J2ME on desktop.
Thanks,
P_trig

How much % of coding required ideally for an XI project?

Hi,
1) I would like to know,how much % of codinng part will be there for an XI project?
2)duration for XI implementation.
ofocurse it depends on project to project, but ideally i would like to know..
Thanks for your reply,
cg

HI,
Look for the thread Effort estimation to integrate SAP & Non-SAP systems for the overall implementation duration.
For the code development effort,
mostly connected to
1. Mapping (XSLT java, XSLT ABAP)
2. RFC development
3. Third Party applications involving SCRIPTS (incase of FILE etc.,)
Add at least 2 to 4 weeks to the overall time.
One point to say at this time is that XI development doesn't only mean Java coding but ABAP too. Above thread I tried posting the overall time frame
to know and process with ABAP as well.
If you are looking for any specific RFC or BAPIC calls, please let us know and probably will be able to give you if I have it in my repositoty.
Thanks,
Srini.

It is unclear where you are having a problem. Is your issue at runtime (when the form runs in the browser) or when working in the Builder on the form?
Also be aware that you will need to sign your jar and include some new manifest entries. Refer to the Java 7u51 documentation and blogs that discuss the changes.

Need to find out how much % of query completed from OEM

Need to find out how long will a query take to run or when I am running the query where can I check to see that X% of my query is complete.
Is that % shown on OEM --> Performance --> Top Activitity?

Under OEM/GC of release 10g you won't be able to see how long the query will take neither how much % of a query are already finished.
I know that this functionality was given in the old release of the OEM (javas based GUI with ll the databases on the left side). I'm missing
that old functionality, too...

thank you very much!

Solutions: Bounce the applications and check the arguments if you can increase it. It is due to memory issue
You can set these values in CommEnv.sh (.cmd for windows) file located in the weblogic_home/common/bin directory.
This gets applied to all the domains under that wls home.
If you want to make the changes to specific domain then edit the SetDomainEnv.sh file located under the domain/bin directory.

How much would be the monthly cost to host a small Linux instance in Azure?

Hello Guys,
I just wanted to ask how much would be the monthly cost of hosting a Small instance of Linux VM in Azure. I doubt this
detail has all the pricing parameters included. It’s just the VM itself it seems.
I know there is a pricing calculator but I’m not sure what parameters would be involved for this very basic instance. If you guys can give me an example calculation or at least point me to the basic parameters to include in the calculation, I will really appreciate
it.
FYI – these instances will be running a FreePBX system. I hope this helps to point out which parameters should be considered and included in the calculation.
Thank you very much,
Arnel

How much work is it to add a callout item to open document in a specified program

Hi, I am hoping someone can point me in the right direction.
I want to know how much work it is to get a Sharepoint developer to add a link to the callout above, e.g. at the top level near OPEN SHARE, or in the sub menu would also be fine. The link would open the selected document in our application which can open
TIFF / PDF and other image files. The link could say "Edit this document in MyApp", or "View this document in MyApp" as examples. We would need to provide this in a modular way, so that customers could optionally deploy it to their own
sharepoint site. A possibility, if the customization is not a big job would be to write a document with details on how to customize the Sharepoint site to achieve this. I'm not sure if Sharepoint has a more intuitive way of sharing this type of customization,
e.g. as an App package.
Any idea how much work is involved approximately in developer hours?
And is there any terminology I could have described better above?
My apologies, I don't have any experience with Sharepoint but we have a requirement to integrate our software with it.
This link https://msdn.microsoft.com/en-us/library/dn135236.aspx has some good info, which I think is in the right direction. But for myself with no Sharepoint experience is a bit above my head.
Any advice is appreciated. Depending how much work it is I may post this up as a freelance job. (basically need to get approval for a budget, and ensure the scope is defined etc.)

Hi,
If you want to add the custom action in sub menu, we can use SharePoint designer to achieve it.
Open SharePoint designer -> Find Lists and Libraries -> Documents
More information:
http://sharepoint-community.net/profiles/blogs/sharepoint-designer-custom-actions
If you want to achieve the requirement of "The link would open the selected document in our application which can open TIFF / PDF and other image files". I suggest you use some jQuery plugin to achieve it.

How much space does JNI_CreateJavaVM

Many of us who try to intialize Java inside another processes address space find problem with space, e.g., we get inexplicable ENOMEM's returned from the JNI_CreateJavaVM call. Apparently, the problem is that the VM needs contiguous address space. But, how does it determine how much it needs?
Consider the solution in [S. Carlson's post|http://forums.sun.com/thread.jspa?threadID=5403763&tstart=0] . This solution looks for a contiguous block of memory large enough to hold the Permanent Generation (+-XX:MaxPermSpace+) space and the maximum heap (+-Xmx+) space. But it doesn't work. I'm guessing this is because the VM wants to put other stuff into that address space. My question is: What? And how do I decide how much space it wants?
Conversely: What would happen if I iterate over the CreateJavaVM call, reducing the space requirement, until it worked? Would that work? I intend to try it, but I'm hoping somebody might tell me if it's a good idea before I waste my time.

In the case of ENOMEM, it cannot. The second attempt to call CreateJavaVM will return -1.
