More then one updates of java installed, can i remove them?

Hello,
i was cheking my software, when i came to a point that i saw like 5 updates of java and they take about 150mb.
Now my question is, can i remove these and just leave the most recent version? or does java need the previous versions too?
Thanks in adnvace.

Most (recent) Java programs are written so that they will run with any recent Java version. Some program authors require that a specific version be used, for whatever reason.
Each Java version is independent and does not depend on the presence of other versions.
Probably, you only need the most recent released version.

More than one version on java installed?

I am having difficulty running a simple 'hello world' program on my machine. I have installed jdk1.3 and I can compile a .java file with no errors but when I try to run it I get the following error: Exception in thread "main" java.lang.NoClassDefFoundError: FileName
This seems to imply that I am using the wrong file name (as I get the same error if I deliberately misspell the filename), but I'm not. I think that there may have been an earlier version of the java sdk (122) on this machine previously - there is an empty jdk122\bin folder. Could this trace of an earlier installation be giving me problems?

No, your classpath is not correct. Search the forums for NoClassDefFoundError, this question is asked very frequently.

Object would have more then one attribute with the tag :VALUE

I'm creating a new component in Ultiboard - a 100 pin connector. This connector (Hirose) has 4 rows of 25 pins. Alternate rows are staggered. I'm trying to name each pin with it's appropiate name: A1, A2, A3 ....A50. Then B1, B2, B3 .....B50.
When I change the VALUE or NUMBER attribute, I get the DRC error message:
This action cannot be completed because the resulting Object would have more then one attribute with the tag :VALUE
Please remove one of the attributes and try again.
Okay, so I've tried deleting the tag and now I can't name the pin at all.
What am I missing?

You should be in the footprint editor to edit the pin name. Select tools>>Database>>Database Manager, highlight the component in your database and click on the Edit icon. In the footprint editor, double click on the pad and a SMT or THT pin Properties dialog appears, select the Attributes tab and highlight the Number row, press the change button and you should be able to change the pin name.

Can i update more then one column using select query.

Dear All,
Can i update more then one column of target table A from source table B. Like
Update table A set A.A1 = (Select B.B1 from B where A.A3 = B.B3).
Above stmt. I am updating only one column. But I want to update more then one column A.A1 and A.A2
Plz give me the possible ways.
Thanks,
Vikas

Yes you can do. Try the below Query
Update A set (A.A1,A.A2) = (Select B.B1,B.B2 from B where A.A3 = B.B3)

How can I restrict more then one user to access the table?

Hi !
I have a problem and two solutions and I am a bit confused as to
which one is the best one and/or can there be any better way of
handling the problem ?
Problem : I have to update a key field of a table when I update
it in the form 5.0 screen. I am basically doing a maintenance of
a table and if a certain field is updated then the change has to
be reflected in two more tables. But the issue is that the field
is a part of the key in those two tables. So all I can think of
is that I need to insert new set or rows for that new value of
the field and delete the old set of records for old values of
the field.
There are two ways of doing it;
1.One option can be to explicitely define two cursors separately
and fetch the values in them one by one and then insert the new
records and then delete the old records in both the tables. This
I feel will be a cumbersome process both in terms of processing
time and the coding.
2.Second option I was thinking can be to create two flat tables
(without keys) and insert the values in them and update the
changed field there and then insert the rows in the respective
tables. Delete the old records in the main tables and delets the
records in these flat tables. This is a bit more faster and
easier to predict and code. This seems to be a better option for
me.
Any comments on these ?
In both the cases I was thinking of making some provision so
that more then one person can't update the table simultaneously.
Since if there are more then one persons doing the processing
then some inconsistency might creep into the whole process.
This is easier to do in the second process as if I check the
data in the flat tables and if there is some data then I can
presume that some one is doing the processing and I can ask the
other person to hold for a while. But in this case how can I
stop more then two people to simultaneously check for the empty
table and start inserting the record ?
I was just thinking of having a sepatare table having only one
field and this will be a key field and as the process begins the
process will insert a fix value say 'Y' in the key field and at
the end of the process the record will be deleted and this way
we can restrict the user to access the process more then one at
a time..? Since you can't have same value of the key in a table
more then once.
Any better way of handling it will be deeply appreciated.
How about locking the table at the begining and releasing the
lock at the end ? Will there be any issue in that? since I am
inserting and deleting the rows in the same transaction.
Comments welcome,
Shobhit

How about performing the update IN the database using a stored
procedure?
By using non-database fields on your form to get the
information, you can then call the procedure in the database to
perform the updates. If an error occurs in the procedure you
rollback, if necessary, and send a message or status back to the
form. If it succeeds you might wish to commit and then re-
execute the form's query -- using either the original key values
or the new key values...

Can I use more then one apple ID on my computer/osx app store

Hi,
I use my MBP/iMac/ipad/iphone for both business and home. Right now everything is setup to my home apple id (and I have made quite a few purchases with that). With the release of the osx app store and FCPX, my company wants to buy these for my computers. But they want to do this on their apple id. Can I run more then one id on a mac? How can I make this work as I know they will want me to start getting more apps as they are released.

You can have apps from multiple Apple IDs on one Mac. The issue will be that to update Mac apps bought with A ID #1 will require signing into A ID #1 in the MAS. And later when apps bought with A ID #2 need an update you will need to sign into A ID #2 in the MAS to update them. If you can keep that straight and can abide that requirement, there should be no issues.
The same will be true to update iOS apps, but using iTunes.

Installing more then one HP All in One networked printer on one computer

I want to be able to install more then one networked all-in-one printer on a single computer.
This is need to be able to move from home office with one all-in-one to a client's location
with another all-in-one but a different model.
I have been told in the past that I can connect one via network connection and one via USB
but this is not an acceptable solution because the printers are networked and used buy more then one system
at a time.
I don't think this is a unique situation for consultants or moble workers.
Is there a way to do this with networked HP all-in-ones printers?

What are the printer models and your operating system. I am using both the Photosmart 2610 and Officejet 7410 networked here and have additional drivers installed for a K60 that is at another location I occasionally visit. Typically you would install the most recent driver and install the printer, then run the installer again and specify "Add printer".

Since iTunes 7 can't import more then one song at a time

When I use File> Add file to library, I can no longer import more then one song. If I select more then one file, iTunes wont import anything. I have my music download to my main iTunes folder, therefor I dont want to use add a folder, also there often is other songs I dont want to import at that time. I can drag and drop from explorer, but its annoying.
Not a terrible bug, but another in the long list for iTunes 7.
