Websites for downloading code-templates (java and jsp) existing ?

Hi,
I'm searching for a website, offering code examples or templates (in java and jsp) for downloading.
For example: A code for creating a new xml-file, login-procedure or sending an e-mail with a java-program, I can customize.
I know, for asp.net such websites for downloading code-templates are existing (e.g. a German website: http://www.aspheute.com).
So I think for java and jsp those sites will also be existing�
Does anyone know some links ?
bye
Chris

Yes, with google - I'll surely find some matches, but I'm looking for links and websites which will be provided by personal experiences.
With google - you won't find any personal experiences...

Java parser for regular expression to java program

Hi All,
I am very new to parser technologies .I am looking for a (java)parser which can read the "regular expression" and can convert it into "java program".Please let me know is there any thing related to this.
Thanks in advance.
Your will be appriciate.
Regards,
Sai.

Hi Jos,
Thank you for your quick response .You're welcome.
If you have any sample code or simple example for how to use those
classes (Pattern,Match) ,will you please send me .It will be helpful for me.Jverd gave you two nice links already in his reply #3
If there is any "open source" for parsering regular expressions.
Please send me I am very new to parser technologies.Note that that Pattern class take care of all the parsing of REs, i.e. there's
nothing 'interesting' left for you to do any parsing whatsoever. Can you
elaborate a bit on what you exactly want to do and learn?
kind regards,
Jos

I upgraded to Lion, no problems, but when I visit a website- for example my bank, or youtube, or any site I have to log into, my computer is no longer recognized and I have to always sign in. Even if I check the box to remember my computer it won't.

My computer is no longer recognized when I visit websites, even if I check the "remember my computer" box. Once I navigate away from the page and then go back, I have to re-sign in. It is really annoying with my banking site, because I have to answer the security questions everytime I log in.

Sometimes, sites divide their content and login logic over multiple servers. In that case, the sites may not recognize that you have logged in if you block third party cookies. Can you check your cookie settings, as described in this article: [[Websites say cookies are blocked - Unblock them]].
During your earlier troubleshooting, did you try the site in Firefox's Safe Mode to rule out an extension as the potential culprit? More info: [[Troubleshoot Firefox issues using Safe Mode]].
You can restart Firefox in Safe Mode using
Help > Restart with Add-ons Disabled ''(Flash and other plugins still run)''
In the dialog, click "Start in Safe Mode" (''not'' Reset)
Any difference?

When clicking on a button on a website, for example "printable view" on a webmail document, nothing happens. When using Internet Explorer, another windows pops up.

I have tried unchecking the "block pop ups" box and still nothing.

Have you thought about installing Firefox 11??
Since add-ons are a common culprit in modifying website functionality, you could test without them.
First, I recommend backing up your Firefox settings in case something goes wrong. See [https://support.mozilla.com/en-US/kb/Backing+up+your+information Backing up your information]. (You can copy your entire Firefox profile folder somewhere outside of the Mozilla folder.)
Next, try starting Firefox in Firefox
[http://support.mozilla.com/kb/Safe+Mode Safe Mode]. Be careful not to "reset" anything permanently if you didn't back up. Just click "Continue in Safe Mode".
Do the links work correctly? If not, you try creating a new (blank) profile: [http://support.mozilla.com/kb/Managing+profiles Managing profiles].
If that works you could try to sort out the cause in your old profile, or move key settings like bookmarks from your damaged profile to the new profile, see: [https://support.mozilla.com/en-US/kb/Recovering+important+data+from+an+old+profile Recovering important data from an old profile].
Hope this helps.

Connect Java programs to ABAP generated Web Services

Hi everybody again!
This time I write looking for code examples about connecting my java programs in Netweaver to Abap generated web services.
Could anyone send me any example, please?
Thanks in advance again!
Alberto.

Hi,
I'm also looking for code examples about connecting Java programs to ABAP generated Webservices... could you, please, send it to me ?
actually, I need to call bapi from a java Web site.
(as an SOAP request ...)
is it better to <b>generate webser</b>vices from the Bapi then call it,
Or shall i keep the Bapi, and call it from a java webservices based on <b>JCO/RFC</b> calls ...
what's more efficient ?
java webservices + Jco calls to the bapi ?
or direct calls to generated abap webservices ?
thanks

How to convert a Java Program into a Service?

Hello Experts,
We want to convert a java program into a Service (not WebService).
then we want to consume this service through SAP PI.
Can any1 please give details as to how can we convert a java program into a service.
Thanks in advance,
~ Suraj

Hi Suraj,
Unfortunately this information is still not enough. Probably I cannot understand right what you are trying to do.
To work with tables and databases SAP uses several specifications, for example JPA API, Java Dictionary and so on. But I am not sure if this is what you need.
Best regards,
Ekaterina

Why can't I run my Java program with just the JRE, the JDK is required?

I've recently written 3 programs in Java using the Netbeans IDE with JDK 1.6 as the default Java platform. The compile-time libraries include the Swing Application Framework. I use BuildDesk from ProductiveMe to package the each program into a Windows installer.
When I install the programs on a new computer without a JRE or JDK being present, and attempt to run them I get an error (as expected) stating that there is no JVM. The messages says that I need to install JDK 1.3 or higher. I downloaded the latest JRE onto the new computer and attempted to run the programs and I get the same error message. My question is, why can't I run these programs with just the JRE installed? Why do I need the JDK? When I install the JDK, the programs run fine. The typical user may not have the JDK on their system, but they likely have the JRE if they've run Java programs before.
Is the answer as simple as there must be library functions being used by the programs that belong to the JDK, but not the JRE? I'd rather a user not have to install the JDK verses the JRE because they may also have to update some Windows environment variables.
Thank you for any help on this issue.

Thanks for your replies. I further investigated BuildDesk and found an option which allows a JVM check but that check needs the JDK. I stopped the JVM check and rebuilt using BuildDesk and it now only requires the JRE to run the programs. The reason why I use BuildDesk is to package more than just the jar file for the user. BuildDesk allows me to create a installation folder structure as well as include any other files in the build. I could just as well zipped all this together for the user but decided against that method.I don't think anyone will question your usage of an installer tool; that is entirely up to you. But what is questionable is that you have problems with that installer tool and then go look for help in a Java programming forum. The next time, go look for help at the source. If there is no way to acquire help (support, a forum, a mailinglist, anything) then that is a very good reason to not use the product in question.

MySQL trying to connect my java program

I am trying to write a java program that I can connect to a MySQL database on my compter. I have typed out this example that is in a text book I have and I am trying to connect my java program to a MySQL database. The version of MySQL is 4.1 which I have recently downloaded onto my computer and is working fine. The problem I am having is in ther places where it says "WHAT DO I ENTER HERE", basically the 'database.properties' , the 'jdbc.drivers' and the 'jdbc.url' string names. I do not know what I am supposed to enter. If you could give me some help with what I am supposed to enter or an example of a java program that already works with MySQL that would be of great help to me. A working example would be the greatest help to me .
Thank-you.

I use Ameritrade website for the stock market. When accessing Command Center it asks for an old version of Java. I have no problems with Chrome.

Mac OSX 10.6 Intel. I can use an older version of Firefox, 3.67 without problems, but any of the new versions wont load the Command Center that allows me to keep track of stock sales and etc. The program asks me to install Java. It seems to want an older version of Java.
I have no problem using Command Center with Google Chrome.

There's nothing Firefox can do about that. You need to contact Command Center.
Using old, possibly insecure, programs is never a good idea.

HT3964 When typing into forms, such as filling out a contact sheet on a website, my first few letters will not appear when i start typing. For example, if I wanted to type "explanation", i might end up with "laxation". This happens in all browsers.

When typing into forms, such as filling out a contact sheet on a website, my first few letters will not appear when i start typing. For example, if I wanted to type "explanation", i might end up with "laxation". This happens in all browsers.
If i backspace everything and start typing again in the same area, it will work properly the second time.
I am using a ~7 month old macbook air with mavericks.
Any tips to get rid of this issue would be greatly appreciated.

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to gather information about the state of your computer. That information goes nowhere unless you choose to share it on this page. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed: Copy a line of text from this web page into the window of another application. Wait for the script to run. It usually takes a few minutes. Then paste the results, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in your browser, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know your password, or if you prefer not to enter it, just press return three times at the password prompt.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test will take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line "[Process completed]" to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report your results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Challange for you, help for me! java program

I am a beginning java student and desparately (again) in help of someone who will check my java program. See below what they want from me, and try to make a program of it that works in all the ways that are asked. Thank you for helping me, i am running out of time.

Catalogue Manager II
Specification:
1.     Develop an object to represent to encapsulate an item in a catalogue. Each CatalogueItem has three pieces of information: an alphanumeric catalogue code, a name, and a price (in dollars and cents), that excludes sales tax. The object should also be able to report the price, inclusive of a 15% sales tax, and the taxed component of the price.
2.     Data input will come from a text file, whose name is passed in as the first command-line argument to the program. This data file may include up to 30 data items (the program will need to be able to support a variable number of actual items in the array without any errors).
3.     The data lines will be in the format: CatNo:Description:Price Use a StringTokenizer object to separate these data lines into their components.
4.     A menu should appear, prompting the user for an action:
a.     Display all goods: this will display a summary (in tabulated form) of all goods currently stored in the catalogue: per item the category, description, price excluding tax, payable tax and price including tax.
b.     Dispfay cheapest/dearest goods: this will display a summary of all the cheapest and most expensive item(s) in the catalogue. In the case of more than one item being the cheapest (or most expensive), they should all be listed.
c.     Sort the list: this will use a selection sort algorithm to sort the list in ascending order, using the catalogue number as the key.
d.     Search the list: this will prompt the user for a catalogue number, and use a binary search to find the data. If the data has not yet been sorted, this menu option should not operate, and instead display a message to the user to sort the data before attempting a search
5.     Work out a way to be able to support the inc tax/ex tax price accessors, and the tax component accessor, without needing to store any additional information in the object.
6.     Use modifiers where appropriate to:
a.     Ensure that data is properly protected;
b.     Ensure that the accessors and mutators are most visible;
c.     The accessors and mutators for the catalogue number and description cannot be overridden.
d.     The constant for the tax rate is publicly accessible, and does not need an instance of the class present in order to be accessible.
7.     The program should handle all exceptions wherever they may occur (i.e. file 1/0 problems, number formatting issues, etc.) A correct and comprehensive exception handling strategy (leading to a completely robust program) will be necessary and not an incomplete strategy (i.e. handling incorrect data formats, but not critical errors),

Here you have the program as far as I could get. Please try to help me make it compact and implement a sorting method.

One thing you're missing totally is CatalogueItem!! A CatalogueManager manages the CatalogueItem's, and is not an CatalogueItem itself. So at least you have to have this one more class CatalogueItem.
public class CatalogueItem {
private String catalogNumber;
private String description;
private double price;
//with all proper getters, setters.
Then CatalogueManager has a member variable:
CatalogueItem[] items;
Get this straight and other things are pretty obvious...

To write a perl script for running a java program from cgi of web server

I have to write a perl script to call a java program(.exe).I want to run this file through the cgi of the web server.
java myprogram
can anyone help me to write a perl script??

It depends on what the java program does. For example, does it parse HTTP headers from standard input, or what?
Are you sure it wouldn't be easier to turn the class into a servlet? etc.
Take a look at IPC::Open2 and IPC::Open3 though. You may need them. (That's just a guess.)

Is RFC destination is required for accessing BAPI from java/VB program.

I am not able to understant that all BAPI are Remote enabled ,but no where I observed that RFC destination is required.
Can any body tell me exact flow and things step by step.
Any example/full source code so that I can call from java program.
I have tried some java code posted here but not able to understand ..
please provide me setttings also in SAP and java system

Hi Nagaraju,
Thank you very much. your post resolve one of my basic need .really appreciate your post.
I was not able to execute bapi BAPI_MATERIAL_GETLIST but I executed BAPI_PO_GETDETAIL succesfully.
Still I have 2 doubt.
[1]. I called BAPI function module(BAPI_PO_GETDETAIL) from simple java program,But I need to call API method ( GETDETAIL) created for this BAPI not direct BAPI function module.
[2] this is something apart from original topic.
I have tested your java code in java as well as similar in ECC 6.0
But I am not getting any output in JAVA program.
I am getting output in ECC6.0 only when I will take internal table lt_mara[] with header line.
if I will take separate workarea output is not coming. I think this is the problem in JAVA also.
Please see the code and tell me where I am wrong.
