Working with 2 JDKs

Alright this is my situation....
I am using JDK 1.5 to develop the company's Java applications. I am using Netbeans 4.1 IDE and I can control within Netbeans which JDK I am using.
Now I am using JDK 1.4 to develop the company's web applications. It would be too complicated to change it all to 1.5. Anyway, I am still using Netbeans 4.1 as my IDE and I also have Tomcat 4.1 installed to run the JSP pages locally because Tomcat is giving me problems when being run with Netbeans.
So I was wondering, when I run my .jar files created from the Java applications, which JDK is being used, if any? How should I configure my PATH and CLASSPATH environment variables? That's the problem I am having.......
Thanks

First, don't set the PATH and CLASSPATH environment variables for your entire system.
Second, Tomcat and NetBeans have their own way to point to the JVM and set their class paths. Simply check the documentation.

How to work with different JDKs on SJSAS PE/EE 8.x domains/server instances

Using this workaround it will be possible to use different versions of java (jdk) for different domains and server instances on a single 8.x PE and/or EE installation. Please make sure that the updated jdk is compatible with application server and the application(s) for which it is being updated. Tested on Solaris as of now.
01 Create a copy of the existing asenv.conf and update the AS_JAVA property to point to the new jdk.
cd <sjsas-install-directory>
create a directory called 'new-config'
copy config/asenv.conf to new-config/asenv.conf
cd new-config
edit asenv.conf and update AS_JAVA property with the desired jdk location
02 Modify the domain/instance specific startserv and stopserv scripts so that they point to new asenv.conf.
Modify the startserv and stopserv scripts in <domain-dir>/bin for domains and <instance-dir>/bin for instances for which the jdk needs to be modified.
for ex. to change the startserv and stopserv scripts for a server instance under node agent.
cd <sjsas-install-directory>/nodeagents/<node-agent>/<server-instance>/bin
edit startserv and change the asenv.conf location.
ASENV_CONF_LOCATION=<sjsas-install-directory>/new-config
edit stopserv and change the asenv.conf location.
ASENV_CONF_LOCATION=<sjsas-install-directory>/new-config
03 Restart the domain/instance to use the updated jdk.
Thanks to Prabhu Velayutham for sharing this work around.

Tested and found that the above workaround is valid for windows-xp as well.
On windows the corresponding files are named asenv.bat, startserv.bat and stopserv.bat.

Configuring OC4J to work with new JDK

Hi all, due to some java related errors, I re-installed JDK.
I had C:\Program Files\Java\jdk1.7.0 and the new one is C:\Program Files\Java\jdk1.7.0_01
I did the following:
1) updated it in server.xml
2) updated it in instanceconfig.xml.
3) Add C:\Program Files\Java\jdk1.7.0\bin to "path" in environment variables. Javac and java command runs fine in command prompt.
4) BI Server, BI Java Host, BI Presentation Services runs fine in SERVICES
But 0C4J is not working. When I try to start it from START, the command prompt just flickers for a split second and disappears.
When re-installing JDK, is there anything else I need to configure aside from those server.xml and instanceconfig.xml? Looking at the manuals, I can only find instructions on configuring when you are installing BI, not changing/reinstalling JDK when BI is already installed.
Many thanks.

Hi J.A.M
This sort of relates to the issue about 500 Internal Error you answered in the other thread. Turns out the there was something wrong with java because I couldn't Javac compile at all from command prompt on a normal Java file (hence BI couldn't either). Which is why I tried to reinstall it.
After installation, I rebooted the machine few times (which in turn would have rebooted everything else).
Running javac on command prompt works, and so does BI Java Host.
Only OC4J is mucking up. Obviously it's not hooked on properly to the new JDK because it was working somehow with the previous (faulty) JDK.
I tried going into C:\OracleBI\oc4j_bi\bin folder (via cmd) and ran "oc4j.cmd -start".
You are right, showed me the error message which I couldn't see earlier. The message was:
"please make sure the JAVA_HOME environment variable is define correctly."
So I configured the JAVA_HOME to point to the new JDK, rebooted the machine. Ran it again.
It still asks me to define JAVA_HOME correctly.

Is there service pack available for weblogic 5.1 to work with JDK 1.4 for NT Environment

Is there service pack available for weblogic 5.1 to work with JDK 1.4 for NT Environment

Hi.
This is definitely not supported, and I don't know that any work is scheduled in the future
to support this JDK on WLS 5.1.
Having said that, I was able to start WLS 5.1sp12 with JDK 1.4 with no errors. I didn't
exercise any features, however.

Can HAT work with JDK 1.5?

Ok, I finally managed to solve this problem. What was happening was that IPv6 was installed on this computer, and as a result Java was trying to do a DNS lookup using a IPv6 socket and failing. With the help of TracePlus Winsock, I discovered that internall Java's InetAddress.getByName does this:
WSAStartup
socket(INET6)
getaddrinfo
WSACleanup
Two solutions are possible - either set the system preference java.net.preferIPv4Stack to true, or uninstall the IPv6 stack. Since I couldn't find a way to set the system preference in a persistent manner (apart from passing in an argument on the java command line), I uninstalled the IPv6 stack.
Hope this helps someone else.

-Xmx1024M is working with Jrockit but not with Sun JDK.

Hi,
We have a window server box with 8GB RAM. in which there are few other processes running apart from that we have more than 1GB space available.
We have weblogic 10.3 present in this system. when we try to Run a managed server with JRockit JVM with -Xmx as 1024M -- it is allocating the space properly.
but when we try the same with Sun JDK , it is failing to allocate memory.
Please let me know if any one have come across this situaton.

Maybe you have a large number of DLLs loaded and have insufficient amounts of contiguous free memory for the Sun JVM? Unlike Sun, JRockit does not require a contiguous heap.

Works fine in JDK 6.0 but not in jdk 1.5.???????

Hi all,
This code converts english date to japanese date but it is working fine in english only. can any body answer why it is so.
Note : No Comiplation problem in jdk 1.5
This code works fine in JDK 6.0 but not in JDK 1.5, Why.....?
SimpleDateFormat sdf = new SimpleDateFormat("yyyy/MM/dd");
        Locale locale = new Locale("ja", "JP", "JP");//locale for Japanese
        Calendar cal = Calendar.getInstance(locale); //japanese calender object
        DateFormat df = DateFormat.getDateInstance(DateFormat.LONG,locale);
        try{
        Date date = sdf.parse("1930/09/27");
            System.out.println(df.format(date));
        }catch(Exception e){
            System.out.println(e.getMessage());
        }

Hi,
If I give the Input date 1930/10/27 (in english), then program must display the date as S5.10.27 (it's japanese date with 'S' indicating ERA)
But this will happpen only when i run the program in JDK 6.0.
In JDK 1.5, for the above input, the output is 1930/10/27 (which is wrong)
Still I don't have compilation and running problems in both. Can anybody expalin why it is so?
I think i tried my best to restate the question.
Thanx

Does the Communications API work with Studio 4

I just installed Studio 4 along with the JDK. The Java version that I am running now is:
java version "1.4.1_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_02-b06)
Java HotSpot(TM) Client VM (build 1.4.1_02-b06, mixed mode)
Running on MS XP.
The Communications API seemed to work just fine on JDK 1.3 with Forte 1.0.
I installed the Comm API as instructed and set my ClassPath:
CLASSPATH=D:\PROGRA~1\s1studio_jdk\j2sdk1.4.1_02\lib\comm.jar;D:\MyProjects\java\GarxFace
A call to:
Enumeration portList;
portList = CommPortIdentifier.getPortIdentifiers();
does not yield any ports at all.
Stranger yet, if I use the auto complete feature in the editor. For example if I type: m_PortID. then no members of PortID show up.
But the code compiles just fine.
Any idea what is going on?

First I found the reason that the auto complete was not working. I had to mount the comm.jar file (you did not have to do this in Forte 1,0, just set the classpath). I thought that I had done that. That is the problem when you work late. ;)
Here is a eexcerpt that I found on a search in another post:
Copy javax.comm.properties to your <JDK>\lib directory.
C:\>copy c:\commapi\javax.comm.properties c:\jdk1.1.6\lib
The javax.comm.properties file must be installed. If it is not, no ports will be found by the system.
Notice it says that "javax.comm.properties file must be installed"
javax.comm.properties is indeed installed in my JDK lib subrirectory, but it is almost like it is not being found.

Can't get jsp:plugin to work with jb5

I am trying to get a Swing applet compiled with JDK 1.3.1 to run on a jsp page using the <jsp:plugin> tag. At this stage it is a ridiculously simple applet (just some JLabels and JTextFields) but I can't get it to work. Here is the jsp code:
<jsp:plugin type="applet" code="nz.astarte.ganttapplet.GanttApplet"
codebase="./WEB-INF/classes" jreversion="1.3.1"
width="400" height="175">
<jsp:fallback>
Plugin support could not be determined
</jsp:fallback>
</jsp:plugin>
When I run it in the jb5 ide nothing shows up at all. OK, I figured the ide doesn't support the plugin, so leaving the ide running (which provides me with a web server) I go into IE (version 5) and enter the url to the page, which is http://localhost:8080/AppletCommunications/GanttApplet.jsp
I get the page, and the gray box saying loading the applet but the plugin console tells me:
load: class nz.astarte.ganttapplet.GanttApplet not found.
java.lang.ClassNotFoundException: java.io.FileNotFoundException: http://localhost:8080/AppletCommunications/WEB-INF/classes/nz/astarte/ganttapplet/GanttApplet.class
Why not? Under the directory where the jsp page is located is the directory structure WEB-INF/classes/nz/astarte/ganttapplet and in that directory is a GanttApplet.class file.
I cannot understand why it isn't found. Do applets work with the jb5 ide? Is there something blindingly obvious that I've missed?
Thanks, Andrew

I appear to have solved it, but it is not clear to me why.
I created a jar file of the required classes, and placed it in the same directory as the jsp file. My jsp code then looked like:
<jsp:plugin type="applet" code="nz.astarte.ganttapplet.GanttApplet"
codebase="."
archive="GanttApplet.jar"
jreversion="1.3.1"
width="400" height="175">
<jsp:fallback>
Plugin support could not be determined
</jsp:fallback>
</jsp:plugin>
This works fine. However I would expect to be able to move the jar file to some other directory, so that the jar file and jsp files are separated. I spent hours trying to work out why it wouldn't work when I had the jar
file in WEB-INF/classes (under the jsp file directory) and had codebase="WEB-INF/classes/". In the end I put the jar file into a directory I defined separately called wotnot and defined codebase="wotnot/"
Now it works. However I still think I should be able to have the jar file anywhere, including WEB-INF/classes and would love for someone to tell me why not!
Thanks, Andrew

CW2000 only supports Java plug-in 1.3.1 and will not work with other version including 1.3.1_02 etc. If you have multiple applications that requires different plug-in versions, you need to access it from a different client to avoid running into problems. This may not sound like a good solution, but can be used as a workaround.

Does oracle jdbc driver 9.0.1 work with sdk 1.4?

Hi All Experts...
Does oracle jdbc driver 9.0.1 work with sdk 1.4.1? Ever since i have moved to 1.4 i am having problems. I keep getting the No Suitable Driver error or NoClassDefFoundError. I have everything in the classpath and i have also tried command line but to no avail. The JVM just refuses to pick up the classes12.zip file from the classpath.
The oracle site mentions that the 9.0.1 driver is for jdk 1.2 & 1.3 but it does NOT mention that it is NOT for 1.4.1. The site very explicitly mentions that the 9.2 driver is for 1.4.1. SO i am a little confused.This question may be stupid, but nevertheless,If i have to upgrade my driver from 9.0.1 to 9.2 then does that mean that i have to upgrade my DB as well?
Experts..please help.. THanks

Thanks a lot, as usual, MOD.
Now only if i can get my JVM to pick up the classes12.zip file from the classpath. I dont know if you read my previous posting today.

How do I get XSQL Servlet to work with OCI 9i

I'm using the most recent jdbc driver (ojdbc14.jar) that works with jdk 1.4. I'm using a 9.0.1 db, and I'm using xdk for java 9.2.0.3. If I specify an oci driver in the XSQLConfig.xml file, I get the following error with a xsql:query request:
Oracle XDK Java 9.2.0.3.0 Production
XSQL-017: Unexpected Error Occurred
java.lang.UnsatisfiedLinkError: no ocijdbc8 in java.library.path
Now why does XDK insist to look for ocijdbc8 if I only have ocijdbc9.dll installed on my client? The config file only allows oci8 in the dburl specification, which is probably why XDK insists to look for ocijdbc8, but I CANNOT specify oci9, which would make sense to me, although it's most likely not a valid specification.
<connection name="9ic">
<username>scott</username>
<password>tiger</password>
<dburl>jdbc:oracle:oci8:@</dburl>
<driver>oracle.jdbc.OracleDriver</driver>
<autocommit>true</autocommit>
</connection>
So how do get XSQL Servlet to work with OCI 9i?

If you are using the latest Oracle9i JDBC driver, which you should be able to get from OTN, it should look for the DLL with 9 in the name.
Perhaps you have a "stale" JDBC driver somewhere earlier on the classpath?

Wlcompile - nested javac elements not working with ant 1.6.1

I’m using windows 2000. I’ve tried with weblogic.jar from Weblogic Server 8.1
SP1 and SP2. I’ve tried with JDK 1.4.1_02 and 1.4.2_04. If I’m using Ant 1.5.3
then everything works perfectly.
I’ve tried to remove the WLS included Ant version to avoid conflicts with Ant
1.6.1 and Ant 1.5.3 (that comes with Weblogic server). I’ve tried to uninstall
Weblogic Server and just keep weblogic.jar, but I still get the same error. I’ve
tried to put weblogic.jar on the classpath, still not working. I’ve tried to remove
all jar files from $ANT_HOME/lib except those jar files needed to run my test
project - ant.jar and ant-launcher.jar, but still doesn’t work. If I change $ANT_HOME
to Ant 1.5.3 and run Ant 1.5.3 then everything works. So it seems to have something
to do with Ant 1.6.1.
Here’s my example code:
<project name="wlcompile_test" default="test" basedir=".">
     <target name="test" depends="init">
<wlcompile srcdir="${src.dir}" destdir="${build.dir}">
<javac debug="${build.debuginfo}" debuglevel="${build.debuglevel}"

Exactly my problem too. I read somewhere that JDK 1.5 has modified its Authenticator class but I am not able to find an example of how to handle a website that prompts you for userid/password.
But I scaled back from JDK 1.5 to JDK 1.4 on Weblogic 8.1.5 but that does not work still. So I sense some issues with Weblogic server.
Can someone help please? Moderators?
