Problem with JUnit Testing from Command Prompt

Hi There,
Related Info:
OS - Windows 7 32 Bit, IDE Used: Eclipse
I'm using the following command to compile the java file from the command prompt:
C:\Users\J\Desktop> javac -classpath .:junit.jar check4PrimeTest.java
I get the error: "package junit.framework does not exist import junit.framework.*;"
How can i fix this?
I have downloaded junit from junit.org the 'junit4.10' and extracted in my Java Folder along side jdkjdk1.7.0_03, jre6, jre7.
I will post my code below for the 'check4PrimeTest.java' file which im trying to test from the command prompt.
package check4prime;

C:\Users\J\Desktop> javac -classpath .:junit.jar check4PrimeTest.javaThat's the Linux way to do it. On windows there is a different list separator. Use this:
javac -cp .;junit.jar check4PrimeTest.java
And use -cp to save you some typing ;) If you want to incorporate unit testing into your builds I would suggest looking into automating it a little more through tool such as ant, maven, etc.

Urgent: Problem with executing an OS command

Hi, all.
My system environment is Netweaver 04 on SUSE LINUX Enterprise Server 9 (x86_64). Temporary License has been installed on the machine.
I'm trying to execute an OS command as an auto-reaction to a monitoring architecture alert.
I have followed the
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/webas/predefined auto-reaction methods of the alert monitor
document.
I have defined operating system command in the External Operating System Command transaction (SM69). I have tested it using transaction (SM49) and it is working fine independently. I have created a auto-reaction method using transaction RZ21 and assigned to the my MTE (Monitoring Tree Element). Then I go to the transaction RZ20. When an alert is arrived to my MTE, the color get changed to Red. When I select the MTE and clicked the Display Alert, It shows the ACTION_REQUIRED status and my command is not executing because my auto-reaction method is not started.
Could someone tell me what could be the all possible reasons for this? Is there any particular service using transaction SICF I have start for this? What most important steps I am missing?
Let me know if anything more informations you people required to answer this.
Its very urgent for me. If someone help me ASAP, it would great help for me.
Thanks in advance.
Best regards,
Sanjay

Can you double check the auto reaction method assignment?
You do not need to have any SICF services enabled for this.

Problem with output string to command

hey i have no idea why this aint working
its a simple output string to command.
what it is supposed to do is make a new directory given by the input string
e.g. mkdir /home/luke/dep
thanks for the help
//methods input save files
     saveFile = JOptionPane.showInputDialog("Save Files To : ");
     //method command for saving files
     //Stream to write file
     FileOutputStream fout;
     try { Process myProcess = Runtime.getRuntime().exec("mkdir" + saveFile );
      InputStreamReader myIStreamReader = new InputStreamReader(myProcess.getInputStream());
      fout = new FileOutputStream ("file.txt");
      while ((ch = myIStreamReader.read()) != -1) { new PrintStream(fout).print((char)ch); } }
          catch (IOException anIOException) { System.out.println(anIOException); }

What you fail to understand is that "aint working" and "Problem with output string to command" tells us absolutely squat about what your problem is. This is the same as saying to the doctor "I'm sick" and expecting him to cure you. As mentioned by Enceph you need to provide details. Do you get error messages? If so post the entire error and indicate the line of code it occurs on. Do you get incorrect output? Then post what output you get, what output you expect. The more effort you put into your question the more effort others will put in their replies. So until you can manage to execute a little common sense then the only responses you will get will be flames. Now is your tiny little brain able to comprehend that?

How do i get a output in CSV of a SQL query executed via SQL Command prompt

Hi All,
I have a question with reference to SQL command prompt. I have a sql query which runs properly and gives proper execution in SQL Management console in GUI.
This report is used to pull the free disk space report of our servers
As i want to schedule it as a report so i want to script it to run via SQL command prompt. I made the script and it works fine if i enter it in SQL command prompt. When i try to extract the output to a CSV File it fails. Below is the details of the command
i am using to query to pull the data. Can anyone help me in getting the output of this query in SQL command prompt.
sqlcmd -W -s , -S Servers FQDN
use operationsmanager
Go
Query:"select Path, InstanceName, SampleValue
from PerformanceDataAllView pdv with (NOLOCK)
inner join PerformanceCounterView pcv on pdv.performancesourceinternalid = pcv.performancesourceinternalid
inner join BaseManagedEntity bme on pcv.ManagedEntityId = bme.BaseManagedEntityId
where SampleValue < '20' and CounterName='% Free Space' and TimeSampled > '2014-08-06 11:00:00.00'
order by countername, timesampled" -s "," -o "C:\DataSqlCmd.csv"
Go
When i enter the command without the quotes when the query is starting and ending and also without the output command (-s "," -o "C:\DataSqlCmd.csv") it is working and shows the output in the command prompt. Below is the screen shot for
your reference.
Due to security reasons i have to erase the server names:
But when i add the line to extract the output ( -s "," -o "C:\DataSqlCmd.csv") It gives me this error:
The exact command would be:
sqlcmd -W -s , -S CINMLVSCOM01.e2klab.ge.com
use operationsmanager
Go
"select Path, InstanceName, SampleValue
from PerformanceDataAllView pdv with (NOLOCK)
inner join PerformanceCounterView pcv on pdv.performancesourceinternalid = pcv.performancesourceinternalid
inner join BaseManagedEntity bme on pcv.ManagedEntityId = bme.BaseManagedEntityId
where SampleValue < '20' and CounterName='% Free Space' and TimeSampled > '2014-08-06 11:00:00.00'
order by countername, timesampled" -s "," -o "C:\DataSqlCmd.csv" -h-1
Go
saying the syntax is not correct or some thing as per the below screenshot.
Can any one please help. Below is just the query whi i use to get the output in SQL management studio.
Can any one make a command for the below quer so i can directly execute and test for getting the output.
select Path, InstanceName, SampleValue
from PerformanceDataAllView pdv with (NOLOCK)
inner join PerformanceCounterView pcv on pdv.performancesourceinternalid = pcv.performancesourceinternalid
inner join BaseManagedEntity bme on pcv.ManagedEntityId = bme.BaseManagedEntityId
where SampleValue < '20' and CounterName='% Free Space' and TimeSampled > '2014-08-06 11:00:00.00'
order by countername, timesampled
Gautam.75801

Can you try the below query?
select Path, InstanceName, SampleValue
from PerformanceDataAllView pdv with (NOLOCK)
inner join PerformanceCounterView pcv on pdv.performancesourceinternalid = pcv.performancesourceinternalid
inner join BaseManagedEntity bme on pcv.ManagedEntityId = bme.BaseManagedEntityId
where SampleValue < 20 and CounterName like '% Free Space' and TimeSampled > '2014-08-06 11:00:00.00'
order by countername, timesampled
-- replace the below query part in the below SQLCMD C:\>SQLCMD -S SERVERNAME -E -d operationsmanager -Q "select * from sys.databases ds with (nolock) where name='master'" -s "," -o "F:\PowerSQL\MyData.csv" -h -1
SQLCMD -S SERVERNAME -E -d OperationsManager -Q "select Path, InstanceName, SampleValue
from PerformanceDataAllView pdv with (NOLOCK)
inner join PerformanceCounterView pcv on pdv.performancesourceinternalid = pcv.performancesourceinternalid
inner join BaseManagedEntity bme on pcv.ManagedEntityId = bme.BaseManagedEntityId

I have a problem with ALV Grid User Command?

Hi Experts,
I have a problem with ALV GRID User Command.
I am calling TCODE IW33 (Order Display) from the ALV output at first time by selecting an order. But, User command is calling IW33 Initial screen with blank value of order. Even I checked in debugging the value what I selected is passing properly, but once that screen (IW33 Initial) displays, value doesn't appear. Then, Manually, I created another session and gone to TCODE IW33 and displayed an order. After that I came out from that order. Then again run my ALV program and selected another order, now order is displaying, but not what I selected current order instead of displaying previous order what I just displayed manually. If I selected any other order, system will display the same order what I dislayed manually.
Here is my code.
FORM user_command_alv USING u_ucomm TYPE sy-ucomm
                       us_self_field TYPE slis_selfield.
CASE u_ucomm.
WHEN '&IC1'.
READ TABLE it_final INDEX us_self_field-tabindex INTO wa_final.
        WHEN 'ORDER'.
          IF NOT wa_final-order IS INITIAL.
            SET PARAMETER ID 'COK' FIELD wa_final-order.
            CALL TRANSACTION 'IW33' AND SKIP FIRST SCREEN.
          ENDIF.
endform.
PARAMETER ID 'COK' also the standard one.
Could you please help me out, Where I did wrong?
If I select any order, that order only should display.
Thanks in advance.
Regards,
Sarayu.
Code Formatted by: Alvaro Tejada Galindo on Jan 8, 2009 2:33 PM

hi,
Please check it once the Paramater ID is 'ANR' for IW33 order number.
Hope this may help.

Sravanthi

Having problems with using shift alt command when using the square tool

having problems with using shift alt command when using the square tool

Marco,
If no good reason, such as the one suggested by Silkrooster, is present, you may try the list, hoping for one of the easy ones at the top.
The following is a general list of things you may try when the issue is not in a specific file, and when it is not caused by issues with opening a file from external media. You may have tried/done some of them already; 1) and 2) are the easy ones for temporary strangenesses, and 3) and 4) are specifically aimed at possibly corrupt preferences); 5) is a list in itself, and 6) is the last resort.
If possible/applicable, you should save current artwork first, of course.
1) Close down Illy and open again;
2) Restart the computer (you may do that up to at least 5 times);
3) Close down Illy and press Ctrl+Alt+Shift/Cmd+Option+Shift during startup (easy but irreversible);
4) Move the folder (follow the link with that name) with Illy closed (more tedious but also more thorough and reversible), for CS3 - CC you may find the folder here:
https://helpx.adobe.com/illustrator/kb/preference-file-location-illustrator.html
5) Look through and try out the relevant among the Other options (follow the link with that name, Item 7) is a list of usual suspects among other applications that may disturb and confuse Illy, Item 15) applies to CC, CS6, and maybe CS5);
Even more seriously, you may:
6) Uninstall (ticking the box to delete the preferences), run the Cleaner Tool (if you have CS3/CS4/CS5/CS6/CC), and reinstall.

Problem with running java program

Hey again!
I missed out some information in last posting.. here is the full description
I have just installed 1.5.0_06 and have set paths and what otherwise is necessary to run the java programs. I was testing the install and run a standard HelloWorld.java program
I got the following error:
Exception in thread main java.lang.NoClassDefFoundError: HelloWorld
what is wrong...
Here is the entire HelloWorld.java
public class HelloWorld
public HelloWorld()
System.out.println("Hello World");
public static void main(String[] args)
HelloWorld hw = new HelloWorld();
I have checked that the path is correct too..
Hopefully someone can help me!
Anders

Your Path is set, probably the problem is classpath.
Change the cmd/command prompt to the directory that contains your HelloWorld.class file, verifying that it exists. If it does, issue this command from that directory:
java -cp . HelloWorld
Important: include the period and surrounding spaces
If that works, you can learn about setting and using the classpath here:
http://java.sun.com/j2se/1.5.0/docs/tooldocs/index.html#general
By the way, just add a reply to your original post with the additional information, rather than creating another post. That eliminates duplication of replies.

Having problems with a Java Telnet Client

I'm trying to write a Telnet Client(for a mud). I've searched the forum but can't seem to find the answer to my problem. The mud sends the ANSI color codes, is there anyway to get java to interpret this, or will I have to make a parser and do all the work by hand?

Try looking up RFC854 & RFC855. A Google Search will give several references. Other Searches include "Interpret As Command", and "Telnet IAC Options".
The keys to telnet communications:
1. Unless it is explicitly a command, it is data.
2. All Commands start with the Interpret As Command (IAC) character, decimal 255 or hexidecimal ff.
3. IAC DO/DONT/WILL/WONT Negotiations for a Telnet Option occurs before IAC SB/SE Subnegotiations. DON'T/WON'T is the default Telnet Network Virtual Terminal (NVT) setting for all options.
4. All Negotiations complete before you get to the data phase.
5. Be ready for Negotiations, at the start and during the middle of the Telnet Session....
Here is an example of decoding Telnet
The remote host may start with the following, shown in decimal:
255, 253, 3, 255, 253, 24, etc...
Viewed as UTF text, this appears to be some "y" characters with special accents above them.
Cheat Sheet:
255 == Interpret As Command (IAC)
254 == DON'T, as is "I DON'T support xyz...."
253 == DO, as in "I DO support xyz..."
252 == WON'T, as in "You WON'T support abc..."
251 == WILL, as in "You WILL support abc..."
250 == SuBnegotiations Start (SB)
240 == Subnegotiations End (SE)
The above has 2 commands:
- 255, 253, 3 == IAC DO Suppress Go Ahead
- 255, 253, 24 == IAC DO Terminal Type
Appropriate Responses could be:
- 255, 251, 3, 255, 251, 24, etc....
OR
- 255, 252, 3, 255,252, 24, etc...
OR
- 255, 251, 3, 255, 252, 24, etc...
OR
- 255,252, 3, 255, 251,24, etc...
Once you get the remotes questions answered, you can move on to the real work of passing data.
Cheers,
Joel.
