Opening java application in Standalone pc

I have build a java application from java classes in JCreator for a client and I have 2 files in the folder, one is a .class and .java files.the program works perfectly but I want to deploy these files so the client can use the program without having to open a SDK Program all the time. is it possible to create file on the desktop that they can use?

My problem is that if there is a new PC , nothing installed in it, can I launch a java application in it ?
My friend asked me if I can build an application in java which I can use in any PC and the application will do something like an installation. In fact he wants to know if java can build an installation like application which will install for example a software on a new PC.
I think I told you more clearly the situation.

My 2700c restarts when I open java applications

My 2700c restarts when I open java applications. I can't play game or use opera mini.

Hi tony1112,
Thank you for your message and welcome to the forums!
Please try these two things to resolve the problem:
Reset your phone to "out of the box" state by dialling *#7370#, followed by your security code (the default code is 12345, unless you have changed it). It's highly recommended to back up your phone with Nokia Suite prior to this, as it will remove all data on your phone. After the reset, restore your phone with Nokia Suite (remember to untick settings) and reinstall the applications from my stuff folder on Nokia Store.
Should this not resolve the issue, reinstall or update your phone software using Nokia Suite by selecting Tools > Software update. If the problem persists visit your local Nokia Care Point and let them have a look.
Hope this helps,
Puigchild

Running Java applications as "standalone"

I am curious as to how to run Java apps in a "standalone" manner. By "standalone", I mean like SUN Java One Studio, where the Java app behaves like a standard executable file.
Currently, I use batch files to call the Java interpreter to run my program; when the program exits, the batch file closes. The main problem with this approach is that the batch file window remains open, and anyone who closes the window closes the program itself... which is not good.
Is there a workaround for this?

Of course there is a workaround for this:
Make a new shortcut on your desktop and as the target use the javaw.exe file. Using this and not java.exe does open qour application without any DOS window! For sure you have to add the class name to load in your shortcut target (e.g. "C:\jdk1.4.1\bin\javaw.exe MyClass").
Voila - the application behaves as a standalone program now.

JCO-Java application unable to open a Frontend GUI session

Hello,

I am having a problem opening a GUI session on a client PC through the JCo java call. It works on some PC's when I am logged in, but not on my PC. But other persons who login on my PC do not have a problem with the application opening a GUI session. I am at a loss. I have had a basis consultant look into this and he could not find a reason for the problem. I have submitted a customer message to SAP and am being told to file this issue in the forum, so here it is. If this is the wrong forum, please let me know which forum would be the correct one.


Problem:
For test purposes, I have created a Java application using the SAP standalone SAPJCO3 vers. 3.0.1. The R/3 backend is 4.6C. The SAPGui version is 7.1 patch level 13 installed on a Windows XP Pro client PC. The application is supposed to start a Frontend GUI session as part of the initial process. This is not working on all PCu2019s for all users. The following are scenarios for two different users on two different PCu2019s, logged on and executing the Java application. The parameters for the Java application are: User, Password, and System Id in this order on the command line after the Java applicationu2019s name. The system Id in our example is PRP in uppercase. This problem happens while connecting to any of our R/3 instances.


Testing of the issue:
Scenario 1:
User gmcghie: This user is the primary user of his/her PC. This PC has not had its registry entries cleaned up for a long time. Starting the Java application from the Windows command line with the supplied parameters, the program is executed and makes the initial connection with the R/3 backend. When the R/3 system sends back a request to start the GUI session, the SAP Logon is executed and opens on the PC. Nothing seems to happen after this.

Here is the JCO exception from the log file:
JCoException eDest: (136)com.sap.conn.jco.JCoException: (136) JCO_ERROR_ILLEGAL_STATE: Launching SAP GUI failed, though it was requested (error message: Communication with SAPGUI timed out)


When you right click on the SAP Logon icon that is in the Windows System Tray on the PC you see an entry that shows a session for Client 000. This is the wrong client being called by the application. The client being called is 600 in this particular scenario.


Here is the connection string sent to backend for scenario 1:
TYPE=A DEST=PRP USER="gmcghie" PASSWD=********** CLIENT=600 LANG=E ASHOST=10.212.120.53 SYSNR=00 TRACE=1 PCS=1 USE_SAPGUI=2


Scenario 2:
User mshin: This user is the primary user of his/her PC. This PC has had the OS re-installed on it within the last few years, hence the registry is likely more clean. Starting the Java application from the Windows command line with the supplied parameters, the program is executed and makes the initial connection with the R/3 backend. When the R/3 system sends back a request to start the GUI session, the SAP Logon is executed and opens on the PC. The connection is made to Client 600 and the process ends. The screens that appear above for the other scenario are not present when the connection is successful. The log file is not included for this as it was empty because it succeeded.


Here is the connection string sent to backend for scenario 2:
TYPE=A DEST=PRP USER="mshin" PASSWD=********** CLIENT=600 LANG=E ASHOST=10.212.120.53 SYSNR=00 TRACE=1 PCS=1 USE_SAPGUI=2

I have the same issue on my PC as the first scenario.
The steps I took to try to get this to work are as follows.
1. Un-installed and re-installed the SAPGui, several times with no change.
2. Compared the registry settings of SAPGui between working and non-working PCu2019s. These were essentially the same.
3. Compared the system variables between working and non-working PCu2019s. These were essentially the same.
It should also be noted that if user u2018gmcghieu2019 from scenario #1 logs into another PC, the program executes correctly (for most other PCs but not all). Finally, if user u2018mshinu2019 from scenario #2 (certain other users as well) logs into Windows on the primary PC for user u2018gmcghieu2019 from scenario #1, and user u2018gmcghieu2019 is used to connect to SAP using the Java program, the program executes correctly. It seems that this would indicate some problem with the useru2019s Windows account on certain PCs.
Why is the connection information being dropped? How is the process of opening the SAPGui on the frontend done?
Any help with this issue is greatly appreciated.
Thanks,
Mark Shirkey

Created Customer Message and got answer. There were settings in Windows Registry for starting the SAP Logon Launch Pad which had to have a value of 1.

Pl help ! ! Opening a servlet URL using stand aline java application

Hi Guys, I have a standalone java application. This application will get executed after some by some thread. What I want to do is when this java application is executed, automatically open a URL in internet explorer which is of my servler/jsp and pass the parameters to this servlet/jsp. This servler jsp will intern use EJB and other services to get the data and display it.
How should I automatically open a IE window and pass parameters using this standalone application.
Pl help ! ! !
thanks , Ava

do you want to open internet explorer, or just access the servlet without internet explorer?
if you want to use internet explorer, you'd want to use
Runtime.exec,
if you want to access the Servlet w/o ie, you would use
URL, and HttpURLConnection classes

Does Open ESB run as standalone application?

Hi all,
does Open ESB run as standalone application (i.e. like ServiceMix) or it works only inside an AS?
Thanks,
Michele

Hi,
I have not tried it out yet, but there is en experimental version on openesb site to download:
"jbi-javase.jar is an experimental version at this point which makes it possible to run without an appserver. Just unjar the version and run the container with the following command: "java -jar lib/jbi_framework.jar". This uses 8699 for jmx port. If you need to use a different port, use -Dconnector.port=xxxx where xxxx stands for the new port."

How to get Portal user from a standalone Java application

Hi,
I have a standalone Java application from where I need to fetch the Portal User Information like userid and email id.
I am using the below line of code
iUser = UMFactory.getUserFactory().getUserByLogonID("e017939");
I have included the jar file com.sap.security.api , But it was giving me the below exception
java.lang.NoClassDefFoundError: com/sap/tc/logging/Location
 at com.sap.security.api.UMFactory.<clinit>(UMFactory.java:55)
 at com.am.wcas.java.mailscheduler.kmaccess.FetchDataFromKM.getiUser(FetchDataFromKM.java:29)
 at com.am.ScheduleEmails.main(ScheduleEmails.java:89)
and I am getting a pop Up message from the Java Virtual Machine Launcher, saying a Fatal Exception has occured and the Program will exit.
Then I went throught he SDN threads and they asked me to include the
logging.jar and com.sap.security.perm.api .
I Included them, then also, it is giving me Exception
java.lang.NoClassDefFoundError: com/sap/engine/lib/logging/LoggingHelper
 at com.sap.security.api.UMFactory.<clinit>(UMFactory.java:56)
 at com.am.FetchKMData.main(FetchKMData.java:30)
Exception in thread "main"
and I am getting a pop Up message from the Java Virtual Machine Launcher, saying a Fatal Exception has occured and the Program will exit.
Kindly let me know if it is possible to access the User info using UMFactory in a standalone Java application. If yes kindly let me know where i am going wrong.
Regards,
Shilpa B.V

Hi Shilpa,
1. Check that you have added com.sap.security.api within the Your Project>Libraries folder (under navigation tab) and also added jars in the build path of the Your Project under project>properties>Build Path.
2. In case you have a DC instead of Web Dynpro Project then you have to add the com.sap.security.api under Your DC>Used DCs and have compile time and runtime dependency added.
Here java.lang.NoClassDefFoundError is caused basically due to only build time dependency added and reference to the jar missing at runtime. Rest the code to retrieve the current user id using UME API and getUserByLogOnID("....") method with/without portal environment would not be an issue at all.

Report Engine SDK - Rbean usage in standalone java application

Post Author: Berndb
CA Forum: JAVA
In BOXI the rebean sdk is available in the Report Engine SDK.
I remember that in the 6.5 world one could use RBEAN interface in a standalone java application.
Is this still possible in BOXI R2?
If yes can you supply a sample classpath which shows all libraries that needs to be assigned.
Thanks in advance.

Ted's right, but for fun, take what you need from:
<installation drive>:\Program Files\Business Objects\Tomcat\webapps\businessobjects\enterprise115\desktoplaunch\WEB-INF\lib
and de-reference what's not needed when your project's done, but be careful.
I've actually done some standalone Swing-based webi report renderers using https://xhtmlrenderer.dev.java.net/ + docHTMLView.getStringpart + TagSoup

Reading a XML file in a standalone java application

Hi,
What are my options if I have a standalone java application running outside any app. server and I need to read an XML file, probably read some of the attributes in the file...? Please explain clearly as I'm new to this. Appreciate your help.
Thanks,
Mahdad

nope you don't need a DTD
you have to write your Java code in a way that doesn't rely too much on the structure:
- avoid getFirstChild().getFirstChild()... because you know that this element is first grandson of that element)
- prefer using getElementByTagName() or some XPath() API
but if the XML completely changes, well, yeah, you have to do some programmation: better think well your document structure in the beginning.

Cannot open MSWord while running java application

Hi everyone
I'm not sure if anyone has encountered this problem before.. I'm running a java application under Windows NT and when I try to open an office document it won't run until that java application has been shutdown. I don't even get an error message for this. Nothing happens at all until the application is shutdown and then MSWord just opens as if nothing had ever happened.
Anyone have any ideas as to what this problem might be?

As a guess.....
1. Run a "hello world" java application. Use task manager and take a snap shot of the processes window.
2. Run nothing else but the java application. Use task manager and take a snap shot of the processes window.
3. Compare the two and eliminate any that are the same.
4. Run nothing else but word. Use task manager and take a snap shot of the processes window.
5. Compare it with 3. Note the ones that appear both times.
6. Run the java application - use task manager to kill what you found in 5. Run word.
Step 6 will probably cause the java app to fail in some odd way. But now you know why it doesn't work.
Of course if nothing is the same in 5 above then that would be odd.

What should be done in certmap.conf for 2-way SSL support from a standalone Java application to an SSL enabled LDAP Server

To support certficate based client authentication using 2-way SSL from a standalone java application which uses JNDI and JSSE1.0.2 to connect to an SSL enabled LDAP Server how do we configure the certmap.conf?Is there any additional setup required at the LDAP Server side apart from enablinf SSL with the option"Required Client Authentication" enabled.The 2 way SSL handshake goes through but the access log file (After configuring the certmap.conf for the issuer DN of the client certficate etc..)shows SSL failed to LDAP DN?But inspite of this access log error the Java client does get an SSL Connection object with which it is able to connect to the LDAP.IS the certmap.conf file being looked up by the LDAP Server at all?

have you out.flush() and out.close() before you call connection.getInputStream()?

HI Ranga Rajan
well, If at all if you have webservice...you can import that werbserivce as External definition in to IR.
How to import:
1) Go to IR and and move to your requied component and there you can see the option called imported objects...select on imported objects where you can give the name and you can select the webservices which you want to use it.
2) Hope you are aware of that a werbservice will have the request and response.
3) Create the mapping program accroding to your requirement.
Go through blogs of Bhavesh and Naveen which talks about calling webservice in a specific condition:
