Software :: Trying To Run Java Program ?
Mar 25, 2011
I have a problem starting a java program.
I installed and am trying to run Antelope an ant file editor. When I try to start antelope I get the trace-back listed below.
When I first tried to start Antelope it asked me where ant/lib was located. I pointed it to /usr/share/ant/lib which has 3 jar files named ant.jar ant-bootstrap.jar and ant-launcher.jar.
I am running in Fedora14. With java version "1.6.0_20"
OpenJDK Runtime Environment (IcedTea6 1.9.7) (fedora-52.1.9.7.fc14-i386)
OpenJDK Client VM (build 19.0-b09, mixed mode) and javac 1.6.0_20
When I try to start it I get
Code:
I have tried it 2 ways, one with the environment variable ANT_HOME set to /use/share/ant/lib - which has some 3 jar files - and also to /home/knox/apache-ant-1.8.2/lib which has about 25 jar files. Same error message both ways.

Trying to use the html editor 'Arachnophilia'... here are the instructions on their website. ".Open a command console (Linux: shell console), move to the Arachnophilia program directory, type "java -jar Arachnophilia.jar" For convenience, this command can be made part of a shell script, and those using X windows can easily make a desktop icon." hoping someone can explain how to run this program.. using a new install of fedora 12 (which has java)...i'm a newbie, trying to go open source on a low end laptop - LOVE Fedora .[URL]..

I want to execute Linux commands using a Java program. I came to know that we can use Runtime.getRuntime().exec("commands") to execute the commands through the program. I'm new to both Linux and Java.

this is my first post and I would like to get some help from you , so what should be the answer for this question ?:::::::::::::the question::::::::::::::::THE UNIVERSITY APARTMENTSThe University Apartments provides apartment rental to university students at affordable rates, with optional facilities:Apartment Type A, 2 bedrooms and equiped with kitchen and laundry facilities. The monthly rental for the rooms in this apartment type is RM300.Apartment Type B, 3 bedrooms includes one master bedroom with attached bathroom but does not have kitchen and laundry facilities. The monthly rental for the rooms in this apartment type is RM200 and students staying in the master bedroom will be paying an additional 40%.
Each apartment may house a maximum of 3 students. Students are required to check out from the apartment unit when the current semester ends.Create an application to manage the university apartments rental:1. Register new student and assign apartment moduleRegister and assigns an apartment to the student for 140 days from the date of registration. The module should retrieve the date automatically from the system clock and calculates the expiry date for the apartment rental. Before an apartment is assigned, the system should allow the selection of the type of apartment (i.e. Type A or B), then check for the number of occupants in the apartment. If the apartment already housed 3 students, it should recommend another apartment unit that is still available. Upon registration, student should pay a RM100 for the utility charges, rental deposit for one month and the rental for the current month.
2. Update apartment status moduleWhen a student moves out from an apartment, the apartment status is updated.3. Reporting moduleGenerates a report of apartments with full occupancy and another report for apartments where rooms are still available. 4. Search module Enable the administrator to search for a student's apartment unit using the student id as the search key. The search result should produce the student�s information and the details of the apartment that the student is staying in.The application should be developed using object-oriented concepts using Student class and Apartment class, implementing the appropriate data fields and methods for the classes. Data may be stored in collections i.e

I've a java program which needs to be executed regardless of whether a user is logged in or not. Currently I've a shell script which executes the java program. I login to the server and run this shell script when the server is rebooted. I would like to start this script automatically preferably as a service so that I can stop and restart this service whenever I update the java program.

I have a java program that runs on Debian as a background processor. Yesterday the Java program stopped running. I looked at the memory usage, the system only had 5MB memory left, so my guess is that the java program ran out of memory to use.
However, after we restarted the java program, we could see that the free memory count started to go up. It kept going up from 5MB to over 400MB. The increase of memory happened slowly, when I measured it, I could see that with each minute passing by, there were a bit more memory added into the free memory pool, and meanwhile, the java background process was running.
I wonder why this would ever happen. It's as if our java program first brought the machine done because it consumed all the memories, then after restart, it starts to give back memories.

I copied the above code into the Command box. The launcher is created, but fails to run the program. Instead I get an error message.

I'm new to the linux world and its been quit sometime since i've done any programming. However, I'm writing a program which simply calculates the load average of a process. In doing this I need to use the uptime command for linux in a java program. I've done a little bit of searching on the net and it mentions this is possiable by using java runtime command. Unfortunatly though I have yet to find a working example of this. I've tried just simply reading the /proc/uptime file but I have no clue how to format the 2 numbers in seconds to make it the same as if you just typed in uptime in the linux command prompt.
