Help me in finding the entry points in the source code of java.....
hi...
I want to design a compilation server and apply some of the optimization technique's like inlining, SSA and others.
So i require to find the entry points in source code from where i can include my code and check the performance of the program at level it is performing .
Please help in this problem....
and i also like to know what are hot methods in java context?

Do you even know Java? Why not just let the HotSpot optimization do its thing?Good point, I would try either of two things.
If you have a good understanding of Java internals and are confident you could optimise code better, I suggest you contribute to the OpenJDK and we can all benefit.
Otherwise I suggest you try using the optimisation built into the compiler and the JVM.
Note: the JVM optimises the code dramatically in ways most normal people won't have thought possible.
The compiler doesn't optimise the code so much as it leaves this job to the JVM.
Two examples;
- say you call a small method often. The JVM can inline this method for you. (the same way a compiler would) However say this method can be over-ridden and later your program calls a different implementation, it can inline both methods even if the new method in a new class didn't exist when the first method was inlined.
- In a 32-bit JVM, 32-bit registers and references are used. In a 64-bit JVM 64-bit registers and references are used without needing to recompile the code. However there is a third option of using 32-bit references in a 64-bit JVM. In this case, it assumes the bottom 3 bits are always 000 so it shifts the reference down 3 bits allowing you to access 32 GB using 32-bit references. Again, you can use this with libraries which were compiled before 64-bit JVMs were available.

How to get the entry point in the ActiveX/COM adaptor
below is the description of the Demo of using the ActiveX/COM to call new seq .
API Demo
1. Manually add a Message Popup step to the MainSequence of a
new sequence file. Save the sequence file as launch.seq.
2. Create another sequence file and save the file as caller.seq.
3. In the MainSequence of the caller.seq file, add Action steps
using the ActiveX/COM Adapter to call into the TestStand API and
launch the launch.seq file in a new execution.You might need the
following two methods to complete this step.
. Engine.GetSequenceFileEx
. Engine.NewExecution
so the question as follows:
1.i call the method of get sequencefileEx
2. call the method of getmodlesequenceFile
3.call the method of evalEntryPointNameExpression
4.call the method of NewExecution.
but at the step of 3. i haven't get the entry point.
so how to solve this issue? thanks

The specific error I am getting in VS2008 with SP1 is: _getContextXml:Unable to find an entry point named 'OpsPrmAllocValCtx' in DLL 'OraOps10.dll' in a .NET 2.x project.
I used dependency walker and looked at both OraOps10.dll (version 1.102.2.20) and OraOps10w.dll (version 2.102.2.20) and the function OpsPrmAllocValCtx isn't in either one of them. I looked at other users machines who aren't having this problem and they have the same Oracle DLLs from the same install that I do too so I am scratching my head trying to figure out what is wrong here and would appreciate any help - and thanks in advance. -
In the Full Featured LabVIEW example, what makes the entry point button reappear?
My question is this: What piece of LV code or invoke node for the TS engine makes the Entry Point button reappear when a sequence file is loaded?
Background:
I've inherited a modified version of the Full Featured LabVIEW UI, which has been moderately modified (Enough so that restarting isn't really an option, but it's still similar enough to use them as comparisons for behaviors). Also, this code was started in LV2012/TS2012, and I'm migrating to LV2013/TS2013, but this behavior was consistent in both versions.
Here's what I've tried:
I found that when the Connect Command executes (See attachment), the button, which is a TSUI.IButton control, is gets greyed out or hidden. In the unmodified example UI that's provided with TestStand, the button reappears when a sequence file is loaded. The problem is that when I load a sequence file in my code, and click on it ahead of running, the button does not reappear. In my code, I can run the sequence successfully by right clicking on the sequence file and selecting Run, so I don't believe the sequence has an error, nor the process model.
Thanks in advance,
Seth

ConnectCommand.JPG 56 KBSeth,
The "options" input of the ConnectCommand function controls this. On the Help page for this input, you can see that there are options for "ignore enable" and "ignore visible". Either of these could impact the functionality of the entry point button. You might try making the options for both buttons 0 and see if this resolves the issue. If not, please let us know.

I've seen lots of discussion about how to remove duplicate copies of the same song, but my issue is different.
iTunes has duplicate entries in its database, but if I do show in finder, then both entries point to the same physical location.
If I delete one entry, then the other entry becomes unusable.
Any idea how I could clean this up? Its annoying because if I select an album to play, then each song gets played twice.@zoo_bink I too have exactly the same issue however it's not affecting all my files.
One solution, which I'm contemplating, is to backup the iTunes Media folder, delete files, uninstall/reinstall iTunes then re-import the files. The issue may have arisen during initial import. (I'm not sure at this stage if Apple allow iTunes to be uninstalled.)
iTunes music collection is showing 58.95GB versus 57.11GB in Finder so it's not a massive deal but annoying nonetheless as deleting entries isn't an option.
Any suggestions welcome.

Firstly some background:
Using Microsoft's managed extensibility framework (MEF), I've created a "Test Tool" framework which accepts plugins. The plugins are generally HW drivers with UIs. I created a NI Vision plugin which does camera discovery, acquisition and image processing. All functionality is exposed via a UI and public methods. The "Test Tool" framework shows the plugin UIs in docking panels (same VS docking panels) and provides a scripting interface for the plugin's public methods.
Ok, now the problem:
At runtime for the "Test Tool" framework and plugin I get "Unable to find an entry point named 'imaqCreateImage' in DLL ...". After a quick debug: the exception is thrown when instantiating the Imageviewer control in NI Vision plugin UI.
I created a plugin test environment which simply references the plugin and adds the plugin's UI to a form. This works correctly at runtime.
In addition, if I remove the Imageviewer controls from the plugin, it works correctly at runtime in the "Test Tool" framework.Have you tried ensuring that the DLL function is actually being exported? You might check out some other forums as this problem has more to do with calling our DLL than the DLL its self. I've found a few other instances of this issue on external forums but I couldn't find any internal resources as you're doing something outside the scope of the intended functionality.

"ZENNW32.DLL is misssing the entry point nwappLoadOD."
We are getting the error
"ZENNW32.DLL is misssing the entry point nwappLoadOD."
I have found this in some other threads in this forum, but they did
not go
in a useful direction for me. This error message is appearing on a
WinXP Pro
workstation before the NWgina appears after boot up. Zen policies are
not
working.
The history of this error is that we installed SP1b on ZfD 4. We thenupdated our workstations from client 4.83 to 4.9 and afterwards the
Zen
agent to the MSI version shipping with SP1b. I have tried deleting the
installpath registry key as suggested in TID 2967507 and also followed
the
other suggestions. No luck. I also think I got the same error at some
point
after rolling back from 4.9 client to 4.83, without updating the
agent.
ZfDagent.msi will install fine on a clean machine that has not had the
previous version of the agent or client installed and policies will
work.> interesting, someone else has reported this problem, but it looked like
> a terminal server issue.
I also found a few thread with this on the forum, but they were with
Win98 or 2k on the workstations, and we have XP, so the client is
different. Also, their problem was different, and the error message about
the missing entry point was just another one of their symptoms. My
problem is that the agent is not working on my XP workstations and I
cannot apply policies or register a workstation (which I can do with the
new wstations where we never had client 4.83 or the Zfd4 agent installed,
and also on our Win98 workstations).
> I'm still not clear on the exact sequence;
Ok, we had client 4.83 and Zfd4 installed. All was well re policies etc.
We updated to SP1b with Zfd, then we updated all our clients from 4.83 to
4.9. Then we deleted the InstallPath key in the registry, uninstalled the
Zfd4 agent and installed the .msi version tht comes with SP1b.
> If so, what options did you choose with client 4.9 during install?
The tech who did the client upgrade tells me that when she did a custom
install of 4.9 (with the old management agent present), she didn't get
the ZfD options in the client she used to get with 4.83. There was only
one box which was ticked and greyed out (i saw this too when I was
playing around). But I have since discovered, that when I took the
management agent off and then uninstalled 4.83 and installed 4.9, I had
all the ZfD options to tick I had with 4.83.
> Have
> you tried 4.9sp1a?
We did try it on a few machines, but found that a staff member who logs
in on lab machines as xxxxx.staff could not log in on the patched
clients. When we put the 'staff.' into the context field in the advanced
section of the login and only his username at the top, it worked! We
tried this on all the patched client machines and it happened on all of
them (I won't be upset if you don't believe me, it's too weird for
words!).
I'll try patching the client and see what happens when I update to
the .msi agent.
Thanks for your help, Shaun.

How to find a line/edge that starts at the same point as the end of another
I have an edges table of Lat/Lon data and for a specific edge I want to find any other edges that have the same start point as the end point of the given edge.
I tried the following query:
select geo_street_id from geo_street s2
where SDO_LRS.GEOM_SEGMENT_START_PT(s2.geom) =
(select SDO_LRS.GEOM_SEGMENT_END_PT(s.geom) as geom from geo_street s
where geo_street_id = 122978214)
but it gets the following error:
ORA-22901: cannot compare nested table or VARRAY or LOB attributes of an object type
Any Ideas?1. to compare geometry to be equal you should use appropriate function (SDO_GEOM.RELATE http://download.oracle.com/docs/html/B14255_01/sdo_objgeom.htm#sthref1561) or operators (sdo_relate http://download.oracle.com/docs/html/B14255_01/sdo_operat.htm#i78531) with specific mask EQUAL.
2. to filter down the resultset in first place you can use the operator SDO_RELATE with mask TOUCH as this will return already the set of lines sharing endpoints, but will also include lines touching eachother not at endpoints (endpoint intersecting the otherone's interior)
something like
select geo_street_id from geo_street s2, geo_street s
where
s.geo_street_id = 122978214
AND
sdo_relate(s2.geom, s.geom,'mask=touch') = 'TRUE'
AND
sdo_geom.relate(SDO_LRS.GEOM_SEGMENT_START_PT(s2.geom),
'EQUAL',
SDO_LRS.GEOM_SEGMENT_END_PT(s.geom),0.005)='EQUAL'
3. if you would do this for the full table, an SDO_JOIN (http://download.oracle.com/docs/html/B14255_01/sdo_operat.htm#BGEDJIBF) might be more appropriate.
4. you might also consider 4 cases:
start = start
start = end
end = start
end = end
5. alternative would be to take only the endpoints of your selected geometry and perform a touch with the edges. using the sdo_util.APPEND on the startpoint en endpoint of your geometry will return a multipoint. although there might some specific cases that this would not return respected result I think
something like:
select geo_street_id from geo_street s2, geo_street s
where
s.geo_street_id = 122978214
AND
sdo_relate(s2.geom,
SDO_UTIL.APPEND(
SDO_LRS.GEOM_SEGMENT_START_PT(s.geom),
SDO_LRS.GEOM_SEGMENT_END_PT(s.geom)
,'mask=touch') = 'TRUE'
Let us know how it works.

OS is Win NT. I see device in MAX , but can not initialise it, and cannot make firmware update.
I do not se device from NT system menager.The instructions on the f5 update are not 100% explicit about what to do for NT. The NatMotion.sys file should not be replaced on NT systems, only on the specifically listed OSes. Uninstall and reinstall the 5.1.1 driver along with the f5 update, however only install the components that do not specifically mention a particular OS.

Entry points for integrating Openoffice writer into Java swing application
I googled the web and also took a look in below 2 web sites, just seems it is very difficult to get an entry point for me to try my frist application with open office writer integrated with my swing application.
http://wiki.services.openoffice.org/wiki/Documentation/DevGuide/OpenOffice.org_Developers_Guide
http://api.openoffice.org/
What my question is:
1. Where can I get the completed jar files for using the open office writer api for my java application?
2. Is there any step by step practical example for using the api? It seems that the above links are quite messy and difficult to find an entry point to get a start, but just contain many segments separated through out the web site.
Thanks much for any suggestion.Information regarding OOo is not on Sun websites, or in these forums. There may be 3rd-party sites that have some info regarding OOo use.
