HT5246 How to know if Java isn't installed

I am new to Apple. How can you know that Java isn't installed when it is listed under Applications/Utilities/Java preferences regardless of whether it requests the Java runtime? Can anyone clarify this for me? Would like to know whether I need to use the tool. Will I be able to use things requiriing Java after installing the Flashback malware remover? Thx

If you open Java preferences and it asks you to download runtime, you do not have Java installed. Today there is a new patch for those of us using Lion who do not have Java installed but may have picked up the infection elsewhere. I understand that some have gotten it from bad Adobe Flash updates. Software update will have the proper patch for you to use depending on whether or not you have Java installed. Check for updates now! As for Java, it is largely unnecessary, but if a web site requires it, you may need it. Also, be sure to disable Java in your browsers, but keep Java Script enabled.

How to know via PowerShell "did user install office on his computer with office 365 or not"

Hello. Sorry for my english.
Subject: How to know via PowerShell "did user install office on his computer with office 365 or not"
I set to users Office 365 ProPlus license, that allows a user to install Office on up to five computers. I want to know, user use this opportunity or not, install office or not.
User can view his installation in the Office 365 portal:
But how I (like admin Office365) can view this information? Maybe via PowerShell?
Thank you...

Hi,
Please see the
blog, I copied the part of here:
====
Viewing a list of Office 365 ProPlus installations
A user can see which computers she has installed Office on by signing in to the Office 365 Portal and going to the
software page.
Only the signed in user can see this information. Even if you are the administrator for your organization's Office 365 subscription, you can't see this information in any of your Office 365 administrative views. This also means you can't deactivate
a user's installation of Office on a specific computer. More on deactivation in a bit.
====
If you have further question about Office 365, I recommend you post the question to Office 365 forum:

It's recommended to download and install
Configuration Analyzer Tool (OffCAT), which is developed by Microsoft Support teams. Once the tool is installed, you can run it at any time to scan for hundreds of known issues in Office

How to know which plug in to install?

I got an error msg "a plug in is needed to display this content" on my Android phone. how do I know which plug in to install?

I'm not sure there is a way to tell that without diving into the code of the page. Perhaps someone else has a way to find out.
But if I had to guess, probably the most widely used plugin on the web is Shockwave Flash, the Flash player plugin. It is not longer included with Android. This article has more information: [[How do I watch Flash videos with Firefox for Android?]]

How to know whether my oracle 10g instalation in unicode supported or not

Hi
i am new to oracle. I have installed Oracle 10g client and server.
I want to know whether the database created can store unicode data/arabic data.
Please guide me how can i find whether unicode support is on for my db or not.
The outputs of some of the queries run by me are as follows:
SQL> HOST ECHO $NLS_LANG;
$NLS_LANG
SQL> HOST ECHO %NLS_LANG%;
%NLS_LANG%
SQL> @.[%NLS_LANG%];
SP2-0310: unable to open file ".[AMERICAN_AMERICA.WE8MSWIN1252]"
SQL> select cust_eng_name,cust_arb_name from custmast;
select cust_eng_name,cust_arb_name from custmast
ERROR at line 1:
ORA-00942: table or view does not exist
Please reply me asap.

1. Yeh that is the thing I want. What are the other steps that i need to do with my Oracle Client/Server for unicode support.
Where i am getting trouble is the Oracle Client/Server unicode support.
And how to decide what character set will suite me best.1. If your application is going to be a "true" Unicode application, you can set the NLS_LANG registry/environment setting on your clients to ".UTF8" to enable true Unicode support.
2. Your database needs to support Unicode, too.
The recommended database character set for this in 10g is "AL32UTF8".
If you currently have a single-byte database character set (WE8MSWIN1252), you need to decide how to get this done.
If you can simply create a new database using the "AL32UTF8" character set, this would be the easiest way.
There are several documents available (e.g. on Oracle MetaLink) that describe in detail how to convert the character set of an existing database. Depending on your data this can be a tedious task involving several steps, so may be creating a new database and exporting/importing the data might be the simplest choice if you need to migrate some existing data.
The recommended national character set is "AL16UTF16", by the way, but that shouldn't matter that much once you have a Unicode enabled database using "AL32UTF8" as database character set.
2. How to set/retrive the "Database Character Set" and "National Character Set". This has already been answered partly. Retrieve:
Database Character Set:
SELECT VALUE FROM NLS_DATABASE_PARAMETERS WHERE PARAMETER = 'NLS_CHARACTERSET';National Character Set:
SELECT VALUE FROM NLS_DATABASE_PARAMETERS WHERE PARAMETER = 'NLS_NCHAR_CHARACTERSET';In most of the cases you can't just simply set/alter the character sets, as outlined above.

How to know that Enterprise Manger is installed?

Hi,
I installed Oracle 10gR2, want to launch EM, but I did not find OracleDBConsole<SID> service in windows services list, and did not find Enterprise Manager Console HTTP Port in the file portlist.ini. So does that mean that I did not install EM? if so, how to repair?
Thanks,
Grace

I chose to install the software only when installing Oracle server, next, installed Oracle client on the same machine as the Oracle server, then created a database using Oracle Enterprise Manager tool from Oracle client.
Now I would like to launch Enterprise Manager, not OEM. However I did not find the services. what do I miss?
Thanks

How to know RAC 11g R2 is installed Using Local User or Domain User on Win

We need to identify whether a local User or a domain User is Used to install 11g R2 Clusterware on Windows 2008.
Here is background:
Oracle 11g R2 RAC is configured on 2 windows 2008 servers.
User "oracle" is used to installed that RAC but we dont know whether local "oracle" user or domain "oracle" user is used to install this RAC.
"oracle" user is present in both the servers as a local user as well as a domain user.
Due to security reasons we need to remove this local "oracle" user but without knowing which user is installation user for rac we cant remove as this will disturb whole rac setup.
Please sugest me some solution ......

Right click on any folder from oracle home -> Security (tab) -> Advance -> Owner.
This will show you who owns this folder and that should be the user who did this installation. You may see 2 users where, one will be local administrator and second one will be the user who did installation.

How does CM know that a PACKAGE is installed

I am a bit unclear on how SCCM knows that a PACKAGE is installed. When a package successfully installs, does the CM client stamp the registry? What if a package fails to install because of a bad command line, does the client cue the
package to try again later? What if I uninstall the package and I want to install it again (required deployment)?
for applications the above all makes sense, just not for packages.

You need to deploy or re-deploy the program. (package aren't deploy but programs are)
Yes, you will need to deploy or re-deploy the program.
No, if you change the version it will NOT update the program on existing clients but new client will get it.

How to know they is space or carrier return when java read a text file.

Hi,
Please help.
How to know they is space or carrier return when java read a text file.
The reason is that. I want to use java for loop to read each part of value. for example: first part is the items name. After the space (I need to tell java when this is a space here and its need to skip) , following by the items prices in double value and space again (need to skip also) and etc.
item name1
item name2
item name3
item name4
item name5
<--- here is the space to skip and another loop to read following items prices
item price1
item price2
item price3
item price4
item price5
<--- here is another spcae again. and so on
thank in advance!

You can check to see if the sting you read in is just nothing, depending on how you're reading it in:
if((str = inStream.readLine().trim().equals("")))
// skip and get ready for the next section
else
// handle the next item
The trim() method gets rid of all leading and trailing spaces and I'm assuming you're using a stream that can use the readLine() method that returns a String.
I hope this is clear. Let me know if it isn't, I'll try and word it different, or post how you're reading the values in if you need more help.

How to know whether a method is thread-safe through the java-doc?

In some book, it says that SAXParserFactory.newSAXParser() is thread-safe,but in the java-doc,it doesn't say that.
newSAXParser
public abstract SAXParser newSAXParser()
throws ParserConfigurationException,
SAXExceptionCreates a new instance of a SAXParser using the currently configured factory parameters.
Returns:
A new instance of a SAXParser.
Throws:
ParserConfigurationException - if a parser cannot be created which satisfies the requested configuration.
SAXException - for SAX errors.
I want to know, how to know whether a method is thread-safe?

System.out is a PrintStream object. None of the methods there use the synchronized modifier, but if you look in the source code, you will find out it is thread-safe, because it will use synchronized blocks whenever it writes some text.
The source code is in the src.jar file which you can extract.
I didn't find any comments about that PrintStream is thread-safe in the API.

I know how to program in java(Should I learn c, c++?)

I know how to program in java. I want to be able to communicate with the hardware on my pc. I also hear that C, C++ is a lower level than java. Lower level meaning it can communicate with the hardware. I know java is very portable could do interfacing and could do so many things with the java programming language. I find the java programmig language cool. Now when I read about the JNI(java native interface) I think I could communicate with methods from java to functions in c++. I want to learn c++ and use it with JNI.
Posting this topic because I want to be sure about what I'm doing.
Thanks
George

in fact, memory management is the main pitfall in C++ programming. The following may give you a few headaches:
- destructors
- header files which try to include eachother
- "memory access violation"
- templates (upcoming java includes generics, which is similar)
- pointers
If you can overcome the above problems, you'll find that c++ is much like Java, only a bit more low-level. Accessing hardware directly however is quite a challenge (espescially under Windows which doesn't allow direct access for as far as I know), but not impossible. I don't know exactly, but I think it involves developing a small driver layer.
It's to bad you learnt Java before C++, the other way around would have been much easier.

How to know if JVM or Java is installed in a machine?

Hey guys I wanna know how to check if Java is installed in a computer?
Thanks.

Alright heres the scenario, When installing the program to a machine I wanna check if there is java installed, so that the program can run to that machine. I just wanna ensure that the programs run in every machine. So I will include a bundle of java to my application when installing. But if there is a java existing already. The installation of Java will not be executed.

How can I resolve java.lang.NoClassDefFoundError?

I am new to Java and have installed it on my Linux Ubuntu 9.04 workstation in order to learn Java. Basic Java programs work, but I am having trouble connecting to a MySQL database. I installed these packages using Synaptic Package Manager, which I thought should cover everything I need for database connectivity: 1.gsfonts-x11; 2.java-common; 3.odbcinst1debian1; 4.sun-java6-bin; 5.sun-java6-jdk; 6.sun-java6-jre; 7.unixodbc.
After these packages were installed, I was not sure if I needed to do this, but I downloaded the MySQL connector from http://www.mysql.com/products/connector/ and installed in a directory called /home/mark/mysql/.
I edited /etc/environment" and added a CLASSPATH to where I installed the connector:
{code}CLASSPATH="/home/mark/mysql/mysql-connector-java-5.1.7/mysql-connector-java-5.1.7-bin.jar"
{code}
I created a very simple Java program based on one I found on the internet. I named the program Jdbctest to test the connection,
{code}import java.sql.*;
public class Jdbctest {
public static void main(String[] args){
System.out.println("running Jdbctest.java");
try {
Statement stmt;
//Register the JDBC driver for MySQL.
Class.forName("com.mysql.jdbc.Driver");
//Define URL of database server for database named mysql
// on the localhost with the default port number 3306.
String url = "jdbc:mysql://localhost:3306/mysql";
//Get a connection to the database for a
// user named root with password carrot.
// This user is the default administrator
// having full privileges to do anything.
Connection con = DriverManager.getConnection(url,"root", "carrot");
//Display URL and connection information
System.out.println("URL: " + url);
System.out.println("Connection: " + con);
//Get a Statement object
stmt = con.createStatement();
//Select from a table
stmt.executeQuery("SELECT host, user FROM mysql.user ");
con.close();
}catch( Exception e ) {
e.printStackTrace();
}//end catch
}//end main
}//end class Jdbctest{code}
but I get this error:
{code}Exception in thread "main" java.lang.NoClassDefFoundError: Jdbctest
Caused by: java.lang.ClassNotFoundException: Jdbctest
     at java.net.URLClassLoader$1.run(URLClassLoader.java:200)

     at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320)
Could not find the main class: Jdbctest. Program will exit.{code}
I don't really understand what this error message is telling me. I've Googled for an explanation, and it seems to indicate that my CLASSPATH is wrong, but I'm not sure what it should be and how to fix it. Any assistance would be greatly appreciated.

Your class JdcbTest isn't in that JAR, is it? So you need the CLASSPATH to also specify where that is. Typical CLASSPATHs start with a dot and then some jars.
