Java plugin is hitting server to much for class files

Hi,
I am moving a jar plugin from the microsoft JVM to Sun JVM. It seems that while the file does run ok I am getting multiple hits to a handler.class file in multiple packages. As you see below:

Can anyonetell me what I need to do to improve the performance of my plugin in this case. Is a parameter not set?
Thanks,
Marc

If you are using the JDK 1.6 plugin, then you can set the "codebase_lookup" property to false to avoid these calls. Documented in
http://java.sun.com/javase/6/docs/technotes/guides/plugin/developer_guide/special_attributes.html#specialattributes
If you're using JDK 1.5 or below, well, tough luck.

Hi
Are you using wli process control?
That uses wsdl and could cause the issue.
I also saw couple of internal bugs CR264315 and CR288904 on the same issue on 9.2.
Since this is a wli issue could you post in the wli newsgroup to get more answers http://forums.bea.com/forum.jspa?forumID=2047 ?
Also you can open a BEA support case at http://support.bea.com and an wli support engineer would help you. Please refer to the Cr numbers above in your support case.

Location for class files for the custom application

Hello everyone.
I want to create new custom application with the short name as "myapp". According to convention what should be the namespace? Should it be mycompany.app.myapp or should it have oracle somewhere in the namespace?
- Yora

Hi Yora,
Package Structure for Standard Application like below
oracle.apps.myapp.webui //Structure for Page and Region.xml(PG.xml,RN.xml,CO.class)
oracle.apps.myapp.server //Structure for .class files(VO,AM)
Package Structure for custom Application like below
mycompany.oracle.apps.myapp.webui //Structure for Page and Region.xml
mycompany.oracle.apps.myapp.server //Structure for .class files
Thanks,
Dilip

Browser looks for class files even tho everything in jars

hi, in my webserver logs I get a lot of 404's for class files. The applet loads fine was just hoping to get the browser not to look for stuff besides the jars I give it. any ideas?
<applet codebase="/" archive="myarchive.jar" code="com.MyClassName">
Thanks

any ideas?Not without a better explanation, example, code etc.

Java version for class file

i have some class files, and i need to know what Java compiler used to compiled that class file (only care for the version number...like 1.4.2, 1.5.0, 1.1.0, etc)
any one know how i can get this info? or any good google keywords?

thanx, since now i know how the class file bytes are set up..i guess i can get the version number by looking at the hex.
tedious (but not that tedious)...thought there be a simplier way...oh well..
thanx again

Server 2012 SMB3 for redirecting files or VHD

Hello,
I’m new to Server 2012 and my question is, should I use Server 2012 SMB3 shares for redirecting files and folders or should I create a virtual HD, put the VHD in the shared folder and do file and folder redirection to the VHD? Is there a preference to use
shares folder or VHD in a shared folder on ? I’m obtaining my information from, Deploy Hyper-V over SMB
http://technet.microsoft.com/en-us/library/jj134187.aspx#BKMK_Step4 under Step 3.
Any insight would be appreciated.
Thanks, Rick

It's not clear what you want to do really. If you want to run VMs on the same machine then hosting them in a loopback on SMB 3.0 folder is not supported configuration. See:
Deploy Hyper-V over SMB
http://technet.microsoft.com/en-us/library/jj134187.aspx
"Loopback configurations (where the computer that is running Hyper-V is used as the file server for virtual
machine storage) are not supported."
Avoid
loopback configurations for Hyper-V over SMB
http://blogs.technet.com/b/josebda/archive/2012/11/14/windows-server-2012-file-server-tip-avoid-loopback-configurations-for-hyper-v-over-smb.aspx
If hypervisor and actual file server are different hosts then you'll be fine.
If you want to run VMs locally on the same host then again using "nested" VHD(x) is by far the best idea.
Did it put a bit more light on the issue? :)
StarWind VSAN [Virtual SAN] clusters Hyper-V without SAS, Fibre Channel, SMB 3.0 or iSCSI, uses Ethernet to mirror internally mounted SATA disks between hosts.

WebLogic looking for class file using the wrong case

During my ant build, I precompile my JSPs using weblogic.jspc. All of the jars and wars are packaged into an ear and deployed to WebLogic 8.1 on Linux. When I access one of our normal screens, everything is good. Things go wrong when I try to access one of our help screens. We have a base help file that includes another file based on the screen code passed to it. The screen code is used in combination with a HashMap to look up the correct JSP to include. This part goes fine. But when the JSP is included, I get the following error. The best I can figure is that the class file is in mixed case (i.e., SampleHelp00.jsp and SampleHelp00.class), but Weblogic is looking for samplehelp00.class.
I'm not even where I should begin looking to solve this. Anyone have any ideas?

Ignore the part about precompiled JSPs being ignored on my development server. Turns out I had a stale cache. I cleared that out and now it recognizes the files.
The problem with that, is now I'm getting an Error 500 when I try to access the page.

I passed the -keepGenerated flag to the precompile task in my Ant build so I could look at the line it's choking on, but it's not very helpful. I'm stuck. I can set up the build so it doesn't precompile the JSPs, but then the QA team wouldn't like me very much.

Searching for class files

I have been using sysinternals process monitor(procmon.exe) to see what coldfusion/jrun is doing on the system. I see thousands of createFile operations as jrun searches for things like component.class, application.class, macromedia\jdbc\oracle\OracleURLParser.class, macromedia\jdbc\sqlserver\SQLServerURLParser.class etc. in c:\coldfusion9 directory which it never finds. I would like to know more about what is happening with this. Do I need to change my class path? Is there an optimal order for class paths? Does this represent a cache miss?

Is there any way by which I can iterate through the folders
and get access to all the class files from the method?The Java Developers Almanac 1.4 has an example of "e33.
Traversing the Files and Directories Under a Directory" here
http://javaalmanac.com/egs/java.io/TraverseTree.html
You "get access to" the class files as you would any other
sort of fle.

My server still taking old class file

Hi,
I have got a J2EE application.
In that I have to modify a Java file.
I made the required changes and check it in the local test environment and find that it is working fine and the changes are reflecting in my application.
Then I copied the class file in the main server and deploy the server(i m using oracle9i server) .
After successful depletion ''THE CHANGES WERE NOT REFLECTED IN THE APPLICATION ".
I found the latest class file is copied in the application(checked the class file using D-Complier).
MY PROBLEM IS : WHY THE SERVER IS NOT TAKING THE LATEST CLASS FILE ??
IS THERE ANY PROBLEM OF WEB-CACHING ??
kindly advise how can i rectify it.
keep smiling.....
Debasis

The last response is correct. You have to stop the server and start it again to reflect the changes in the class file. Only the JSP files can be changed dynamically while server is running as the container compiles it if there is any change in the file. All other files need a server restart.
Thanks

Looking in the wrong directory for class file

My javabean looks like this:
<jsp:useBean id="mailer" class="MailerBean">
<jsp:setProperty name="mailer" property="*"/>
<% mailer.sendMail(); %>
</jsp:useBean>
The actual MailerBean.class file is in ROOT/public_html/servlets directory. The file that uses the above javabean is in ROOT/public_html/clearresults directory. I have tried a bunch of different lines of code to point to the servlets directory with no success. The javabean continues to point to the ROOT/public_html/clearresults/MailerBean.class file when it should point to ROOT/public_html/servelts/MailerBean.class. How can I point the MailerBean class to the servlets directory without moving the file that uses the javabean?

Generally you don't have to write code to say where a class is, and I don't know what "pointing" a class is. Things that run servlets and JSPs have rules about where they will look for classes. All you have to do is put your MailerBean class where the rules say to put it. Often that's a directory called something like .../WEB-INF/classes, but check out the rules for your product.

WebLogic server's charset for writing files

Hi!
I have the following situation. Webapp (servlet) instantiates a class, which periodically writes data to files. The data is written to a file using the following code:
fos = new FileOutputStream(outfile);
//Don't wanna specify charset here
fos.write(line.getBytes());
The question is, where do I specify the charset to be used? Weblogic-application.xml has the following definition:
<application-param>
<param-name>webapp.encoding.default</param-name>
<param-value>UTF-8</param-value>
</application-param>
Should this define also the encoding used when writing files, or should I define it in the server startup somehow, or what?
