Cannot use "java:" prefix in Context.lookup()

I have observed a NullPointer exception when the "java:" prefix
is used during a JNDI lookup with WL 5.1.0 Service Pack 4 on WinNT.
Context ctx = new InitialContext();
Object obj = ctx.lookup("java:comp/env/ejb/BeanHome");
The work-around of removing the "java:" prefix works fine:
Object obj = ctx.lookup("comp/env/ejb/BeanHome");
The "java:" prefix is suggested in the EJB 1.1 specification.
Here is the exception's stack trace:
java.lang.NullPointerException:

Cannot use java

not sure if i am in the right area but thought i would start here.
i am trying to view a webcam to watch my dog at daycare, when i try viewing it i am told that i need to upgrade my java. did that java told me i downloaded it and ready to use.
but everytime i log into the site and click on the webcam i get a blank screen. i then get a message that my security is blocking me from using java.
can someone tell me step by step what my security should be set at in order to use java. as far as i can see i have everything right.
but still cannot view it on my macbook pro. i have OS X 10.9.3.
i can view the webcam on my iphone and ipad but i need to refresh every couple minutes.
which then brings me to another question.
when i sign into the daycare it ask me if i want to use JPEG, GIF or 3G. which is the correct one.
thank you for all and any help.

dogwalker 2,
there are currently three “latest versions” available — one based on Java 6, which is distributed by Apple; one based on Java 7, which is distributed by Oracle; and one based on Java 8, which is also distributed by Oracle. Did you install the latest Java from Apple, or one of the latest versions from Oracle? If you’ve downloaded the latest Java 6 from Apple, then you’ll need to also download the latest Java applet plug-in from Oracle if your dog daycare’s webcam access is provided as a Java applet — and that plug-in comes as part of Java 7 or Java 8, either of which can be downloaded from Oracle here. Once one of these is installed, you’ll have the Java pane in System Preferences again, and you’ll need to adjust its settings appropriately.
Any software can be the source of security problems. The keys are to only use what you need to, when you need to, and to stay on top of security updates as they’re released.

I cannot use JAVA with Firefox but I can use it with Internet Explorer WHY?

I have never had a problem when JAVA 7 was needed to use a program. Until now. Firefox will not allow me to use Java. I have to open Internet Explorer when working with any program and it works.

To protect Firefox users, Mozilla has blocked/disabled Java 7 u6 and below due to serious security flaws in the previous versions of Java 7. The security flaw would also apply to any other browser using the affected versions of Java 7. You can see the version of Java and whether it is disabled in Add-ons > Plugins; look for "Java Platform SE...". See - https://addons.mozilla.org/en-US/firefox/blocked/p138
You can check your '''''enabled''''' Plugins at any time - https://www.mozilla.org/en-US/plugincheck/

I cannot use java jre in lion, I cannot use java jre in lion

Hi I need to use an online banking service which requires Java - I have ensured that my Java is fully up to dat and even installed the developers version but I cannot access the online banking service.
I am using Lion - any ideas?

Uninstall any Java you have now and install this
https://support.apple.com/kb/DL1421
Reboot and see if that works, it could be your site isn't compatible with Lion/Safari yet.
You can use Firefox or even Chrome web browers, see if those work.

Cannot use Java Mail in Oracle 8i

I have loaded Sun's API Java Mail (and Java Activator) into
an Oracle 8.1.5 server running on a Windows NT 4.0 server.
I have also created a small Java-application that tries to
send emails. The application is stored in database as a stored
procedure.
However, when I try to send a mail through my stored procedure
I get the message:
'ORA-01041 internal error. hostdef extension doesn't exist'
followed by an end-of-channel error.
It works fine when I run my Java-program stand-alone, without
any database involved.
I need some help with this one...

You cannot use java directly inside forms. You can either create a java-bean to enhance the GUI (as you have some UI-components in your java-code, i guess this would be the direction) or use the java-importer and call server-side-java. Both require that you are running forms in a web-version and not as client-server.
What exactly is your requirement?

XSLT Mapping : RFC Lookup using java helper class

Hi All,
I am doing RFC Lookup in xslt mapping using java helper class. I have found blog for the same (http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/05a3d62e-0a01-0010-14bc-adc8efd4ee14) However this blog is very advanced.
Can anybody help me with step by step approach for the same?
My basic questions are not answered in the blog as:
1) where to add the jar file of the java class used in xslt mapping.
I have added zip file of XSLT mapping in imported archived and using that in mapping.
Thanks in advace.

RFC Lookup using Java Mapping program - Examples

Dear Experts,
I am working on a scenario which is using 1:N mapping. For deciding the target message I have to use RFC Lookup to call the backend ERP system and there are 2 ERP systems involved in this integration. As I am using Java Mapping and never did a RFC Lookup in Java. I kindly request you to give me some examples which I could use for my RFC calls in my Java Mapping. Simple example will do.
Client is adamant to use Java mapping, I could achieve this easily using XSLT or Graphical Mapping.
Advance Thanks,
Pradeep

Hello,
why don't you use Extended Receiver Determination Defining Extended (Dynamic) Receiver Determination - Integration Directory - SAP Library?
What you can do is create a Message Mapping between your source message and Receivers message type. In this message mapping you can use your RFC to generate the target message.
For example, lets say we have the function ZFM_GET_INTERFACE_INFO used to generate the List of Receivers given a source message. You could create a Message Mapping as below:
In this case, the RFCLookup box look as below:
The receiver determination configuration would look as follows:
Afterwards, you will need two specific message mappings for the two ERP systems.
Summarizing, you'll need:
1.- A Message Mapping: Source Message to Receivers Message Type (This one uses the RFC Lookup)
2.- A Message Mapping: Source Message to Target Message for ERP 1
3.- A Message Mapping: Source Message to Target Message for ERP 2
In Integration Directory you'll have 1 Receiver Determination(Source system, Target System determined Dynamically) and 2 Interface Determinations (Source System to ERP1, Source System to ERP2), etc.
I hope you find it useful.
Regards!

XI: How To Use JAVA generic Class to perform SAP data Lookup........

Hello All,
I want to create a generic class which is used to perorm SAP data lookup.
I don't want to use Jco or RFC channel..
Is there any other way to do this?
waiting for Reply
thank in advance.

Hi,
use RFC channel
you can wrap it up like this:
/people/morten.wittrock/blog/2006/03/30/wrapping-your-mapping-lookup-api-code-in-easy-to-use-java-classes
why do you want to create something diffucult to maintin and non standard if
you can use the RFC API ?

Firefox needs 32-bit plugins, so you'll need to install 32-bit Java for Firefox.
No, you can't change Firefox from 32-bt to 64-bit. There is a Nightly 64-bit version (alpha) of Firefox, but it is used only to test for regressions until development is resumed.
