WL 7.0 jCom Compling

Hello,
I stubbed out my COM dll fine. But when I went to compile the .java files, it could
not find the com.bea.jcom.Dispatch class. This class was not in weblogic.jar.
Anybody know where it is?
TIA,
Jeff

There are a whole bunch of objects besides the documented Dispatch that are missing
from weblogic jar. I changed the locations to com.linar.jintegra and finally got
it to compile, but could not make any invocations because I got Jintegra licensing
error messages.
My attempts to go in the COM-WLS direction have been equally unsuccessful. Using
a late-bound client, binding with the jndi moniker does not seem to work. Also,
attempting to obtain a jvm moniker results in the following error:

Is there a working example for communication from Java to Com?

Hi,
This is a known issue. The Dispatch class is located in com.linar.jintegra.Dispatch.
For now you'll have to hand-edit your generated classes to import andreference this
class location. If you have more than a few generated classes, a quickscript (perl,
python, sed, awk) is probably best suited to this task.
We apologize for the mistake. The issue will be resolved in a futurerelease.

How to solve the "type mismatch" error in jCOM early binding program?

I got a "type mismatch" error jCOM early binding program.
I use the VB as the jCOM client to access the EJB deployed on WLS7. While using the
object parameter like "java.lang.Integer" in EJB method call, I got that error message
and my VB client had to be stopped?
The same situation, the VB program work perfect when using the "int" as the parameter.
And I try to instance the "myTLB.JavaLangInteger" in my VB program, but how ? The
"New", "CreateObject" and "GetObject" all failure, I don't know what to do next ???

Hi,
This problem Could happen when you referesh quality or test system.
Your delta setup for the related master and transaction data needs to be reinit.
What happens is when you init. the delta and subsequent delta is all maintained in your source system
please check Notes 852443,424848,834229
Hope this helps
Thanks

Sorry! I have not explain it clearly.
To solve it , you do following :
1. locate stdarg.h ( or find /usr -name stdarg.h ), assume you find a stdarg.h in /usr/lib/gcc-lib/XXX/XXX/include/stdarg.h
2.ln -s /usr/lib/gcc-lib/XXX/XXX/include/stdarg.h /usr/include/stdarg.h or cp /usr/lib/gcc-lib/XXX/XXX/include/stdarg.h /usr/include
( above 2 step was to make Pro*C can find stdarg.h in /usr/include )
3. for file stddef.h do like step 1,2
4. append a line in your Pro*C config file:
CODE=ANSI_C

WRT54G - Is there anyway to add a separate VPN/Firewall device to complement this product

I have a WRT54G v.2 device and I hate to throw it out. My dilemma is that I'm in need of a VPN/Firewall device as well. So I would like to know if there is a device that I can purchase from Linksys that will provide the VPN/Firewall features as a complement to my existing WRT54G? I'd appreciate any info someone might be able to provide.
Regards.

Hi,
you have options between the RV series of VPN routers and the BEFSX41 and the BEFVP41.however you will have to change your network a bit.Your main router will have to be either of the VPN routers.The DHCP of the wrt will have to be disabled and you will also need to change the ip of the wrt from 192.168.1.1 to 1962.168.1.2
The connection will be.modem to internet port of the VPN router and then from port 1 of the VPN router to port 1 on the wrt.Do not use the internet ports of the wrt.

JCOM throwing SocketException: Connection reset by peer: socket write error

I have an ejb which is calling a simple ActiveX component using JCOM.
Ocassionally the ejb loses the ability to connect to the ActiveX component. Any attempt to call a method results in a java.net.SocketException: Connection reset by peer: socket write error.
However the ActiveX component continues to run correctly. I can still connect to it using a vb test client. This is using com to connect, not DCOM as used by JCOM(JIntegra).
The application server and the ActiveX component are running on the same server.
Any suggestions as to why the JIntegra DCOM request could be failing?
Thanks,
Greg.

I did everything earlier except the second point you mentioned. Everything started
working as soon as I added a line to call com.bea.jcom.AuthInfo.setDefault() method.
I didn't think this was necessary since I already gave permissions to that user
using DCOMCNFG. Thanks for you help.

hi anil,
can you post the snippet of java code that is calling the methods
from your COM object and post the following logs
jcom.log
- In your java code, add the following line to the start of your
initialization code.
com.bea.jcom.Log.logImmediately(3, "c:\\temp\\jcom.log");
config.log
- Run the checkconfig utility to generate this log
checkconfig /typelib <path to tlb> config.log
thanks

Thanks for the info. I had already done this before. I checked
everything
a dozen
times. I am not sure why this is happening. Please let me know,
if
there
are any
other ideas.

hi anil,
The exception you are getting, indicates that your java client
does
not
have
sufficient permissions to access your com component.
if you are running your java code and com component on the same
machine,
- make sure that your jcom/bin directory is in your path environment
variable
- run the DCOMCNFG tool to configure accesss for the interactiveuser
or the
user you are logged in as.
if you are not running your java code under windows, add this
call
in
your
java code:
com.bea.jcom.AuthInfo.setDefault("nt domain", "user", "password");
- use the DCOMCNFG tool to configure has dcom access to the
com
component for this user
let me know if this helps

Using JCOM in Native mode JIntegra Registry Entry Error

Hi
When I am using the weblogic's jcom feature and when I turn on the native mode
feature I get the foillowing error
The WebLogic Server did not start up properly.
java.lang.RuntimeException: RegSetValueEx failed
at com.linar.jintegra.NativeObjectProxy.registerJvm(Native Method)
at com.linar.jintegra.Jvm.register(Jvm.java:202)
at weblogic.com.COMService.initialize(COMService.java:68)
at weblogic.t3.srvr.SubsystemManager.initialize(SubsystemManager.java:11

at weblogic.t3.srvr.T3Srvr.run(T3Srvr.java:337)
at weblogic.Server.main(Server.java:32)
Reason: java.lang.RuntimeException: RegSetValueEx failed
The google search took me to a jintegra support page which says that
The
user of the application MUST have access privileges to the registry
(specifically, HKEY_LOCAL_MACHINE->SOFTWARE->Linar->JintMkr->[jvm name]).
I uninstalled and installed the weblogic hoping that this registry entry would
figure in my registry but it does not - so folks any clues!

The got the same error when I try to register the jvm using regjvmcmd command. Unfortunately regjvmcmd does not like dots in the jvmid. e.g., wlsgam47.gammadom.com will not work. So, you have to use wlsgam47 and then go to the registry and update the following property manually as HKEY_LOCAL_MACHINE->SOFTWARE->Linar->JintMkr->wlsgam47.gammadom.com.
Ofcourse you should have administrative privileges to do this.
After that the weblogic server starts without problem.
Good luck !

Bit Complement in an Expression Node

I can use bit complement in a formula node but not the expression node. The
"~" tilde is the only text in the expression node. The error is "~#" with
# being the error. The input is a U8. Thanks in advance for any help.

Hi Catherine,
I've tried your suggestion earlier and tried it again after your
post but it still doesn't work. I am new to expression nodes so maybe my
syntax is incorrect. To do the same in C language I think it looks like
this: "a = ~ b;". I made a picture and a copy of the error. Let me know
if you see anything wrong. Thanks!
Error on line 1 is marked by a '#' character: "~#"

JCOM with Weblogic6.1(migrating from weblogic 6.0)

Hello,
We are currently running our application on Weblogic 6.0. Also we have a VB client
which talks to Enity beans deployed in the Weblogic server, via JINTEGRA(jintegra.jar)
Now, we are planning to migrate from Weblogic 6.0 to Weblogic 6.1. In this context,
I have following questions,
1]     Can I use JCOM for my requirement(talking to EJB's from VB client)
2]     Is JCOM shipped along with Weblogic 6.1, if so is it shipped as a separate
jar file or as part of weblogic.jar
3]     With Weblogic 6.1, do I have to still install Jintegra.jar for accessing my
beans from VB or does JCOM solve the purpose ?
Would really appreciate if you could share your thoughts

help me.

I hope this question is not too simple. Does your CLASSPATH contain the path to the beans package .class file location, or the jar file that contains them?

Problem in compling with G++ compiler

Hi ,
I have written one application in java which is calling the C API and after processing it is giving result to the Java application.
Now i have changed the extension of the C API to .cpp then i am compiling the same source code using the g++ complier but it is giving error in the function where i am calling my Java function in C API .
Can any one tell me is there is any thing wrong i am doing ...
For compiling the C API i am using the command (It is compling fine )
gcc -o libpixim.so -shared piximImager.c -I /home/java/include -I /home/java/include/linux
For compiling the C++ API
g++ -o libpixim.so -shared piximImager.cpp -I /home/java/include -I /home/java/include/linux
But it is giving error ....

I know both langugaes are not same but c is a sub part of C++ if it is compling in C then with C++ complier it also should compile.
I am found the solution for that
ie
g++ -o libpiximImager.so -shared -I /home/narendra/javatest/j2sdk1.4.2_15/include/ -I /home/narendra/javatest/j2sdk1.4.2_15/include/linux/ -lc
I have miss to put the -lc option
