J2EE library path

we can use method System.GetProperty() or similar to get J2SE library path.
is there a Java method which can get J2EE library path?
thx

no one knows the Q?

Library paths and environment variables

Hello,
I am using 10g AS 9.0.4 on a Unix system.
I am trying to convert an old JSP web application to work with 10g. It is not an EAR/WAR file so I am manually trying to set it up under the "default-web-app" folder. It uses a number of java class files which currently reside in $J2EE_HOME/default-web-app/WEB-INF/classes/mystuff.
These class files require access to a number of libraries. I foolishly believed that they would be accessible if I were to place them in the $J2EE_HOME/default-web-app/WEB-INF/lib folder, but that did not work.
I read that OC4J uses a "catch all" lib directory at $J2EE_HOME/applib. I copied the library files there and they still did not work.
Frustrated, I tried to print out the environment variables for the server - only to find that this function is not supported.
I managed to print out the library path by creating a Java class files which returns the following as a string:
System.getProperty("java.library.path");
This (when called from a JSP) prints a number of different library paths, none of which match those found listed in the $J2EE_HOME/config/application.xml file. I placed the library files in one of the paths listed by the "java.library.path" and it worked!
3 questions:
1. How do you print the server's environment variables using a JSP? This strikes me as a very useful function for sorting out library and path issues. Do a search on Google for "print environment variables OC4J" or something similar and there are no useful pages suggesting how this can be done.
2. Why are the default library paths different on the server than to those specified in application.xml?
3. How do I change the LD_LIBRARY_PATH (or any environment variable for that matter)? I have tried adding the following line to $ORACLE_HOME/Apache/Jserv/etc/jserv.properties without success:
wrapper.env=LD_LIBRARY_PATH=/my/custom/library/path
Any help you can offer would be most appreciated.

Thanks very much for a such a comprehensive response
- it has helped answer a lot of questions, especially
being able to print out the system properties. That
will be really useful!
No worries at all Rob.
The main hurdle is that the libraries are indeed
native (*.so) libraries. I hadn't considered that
until you pointed it out in your message. Can I
assume, then, that $J2EE_HOME/applib and
$J2EE_HOME/default-web-app/WEB-INF/lib are only
designed to handle Java's .JAR librares? That would
explain why placing the native libraries in there
didn't work, but is there a way of getting such
native libraries recognised and bundled up in a
WAR/EAR file?
Yep, that's it.
Our proprietary applib and the servlet specs web-inf/lib are only dealing with Java archives.
The J2EE specs don't cover how to deal with native libs like this.
Now I've NEVER EVER tried it, but it's worth a shot of at least trying -- for simplified packaging purposes, what you may be able to do is to distribute the .so's within the web-inf/lib -- and then just set that directory (where's its realized on the server after the app is deployed) to be referenced witihn the LD_LIBRARY_PATH. I'd expect our deployment manager will just ignore files it doesn't know about, so arguably you should be able to at least distribute them with the standard archive.
You'll need to specifically set the LD_LIBRARY_PATH as a separate task outside of the deployment operation though.

This is where things get a bit weird, and is partly
my fault during the installation of 10g AS.
We already had an existing installation of Oracle 10g
Database (10.1.0) at $ORACLE_HOME under the user
"oracle". I logged in as the user "oracle" to install
the Application Server into a different location (In
this case, "$ORACLE_HOME/../ias10g_9.0.4" - let's
call this $IAS_HOME). So there is no separate user
account for Oracle Database and Application Server
(and hence no separate $LD_LIBRARY_PATH).
If I log into UNIX as the user "oracle" and echo the
LD_LIBRARY_PATH, I get the following directories:
$ORACLE_HOME/lib
/usr/openv/netbackup/bin
/usr/dt/lib
/usr/lib
I use this user to do "opmnctl stopall" and "opmnctl
startall". If I then print out the library path from
a JSP using
"System.getProperty("java.library.path");", I get the
following paths:
$IAS_HOME/jdk/jre/lib/sparc/server
$IAS_HOME/jdk/jre/lib/sparc
$IAS_HOME/jdk/jre/../lib/sparc
$IAS_HOME/opmn/lib
$IAS_HOME/lib
$IAS_HOME/usr/lib
Which is totally different to those listed by
$LD_LIBRARY_PATH at the command line, which means
they must be coming from somewhere else.
It gets worse - my application is trying to call a
native library that is only present in the
$ORACLE_HOME/lib32 directory (libclntsh.so.10.1), so
unless I can include this path in the
"java.library.path" on the Applicaiton Server, then
my program will not work.
So, how do I change the "java.library.path" when the
values aren't coming from $LD_LIBRARY_PATH in the
first place?
The utility $IAS_HOME/opmn/bin/opmnctl is actually a shell script.
It has this section which sets the LD_LIBRARY_PATH:
if [ -z "$LD_LIBRARY_PATH" ]
then
LD_LIBRARY_PATH=$ORACLE_HOME/opmn/lib:$ORACLE_HOME/lib ; export LD_LIBRARY_PATH
else LD_LIBRARY_PATH=$ORACLE_HOME/opmn/lib:$ORACLE_HOME/lib:${LD_LIBRARY_PATH} ; export LD_LIBRARY_PATH
fi
So if you have an existing LD_LIBRARY_PATH env var set, it should just be putting its paths onto the front of it.
What you could try as a quick test is to edit the opmnctl script (after taking a backup of course) and either appending the path you need to it, or just add some debug statements to output the LD_LIBRARY_PATH value it ends up setting so you can try and work out what's causing it.
I expect these other entries:
$IAS_HOME/jdk/jre/lib/sparc/server
$IAS_HOME/jdk/jre/lib/sparc
$IAS_HOME/jdk/jre/../lib/sparc
are coming from the JRE when it is launched, in probably a similar manner to our opmn entries.
I really appreciate your help, and I bet if anyone
can answer these questions, you can! ;-)
You're very welcome.
cheers

No jacob in java.library.path.doc

I am running Developer Suite 10g on Windows XP. I have the OC4J instance running. I am using WebUtil and trying to use the OLE2 stuff. When I execute the code, nothing happens (see errors below) except all my buttons go dead. I checked, and it does not seem that I am getting the Jacob, JNIsharedstubs, and the d2kwut60 DLLs to download to my Jinitiator directory. I removed and reinstalled Jinitiator, but still nothing. If I manually copy the DLLs to the directory, I at least begin to get OLE2 errors. I read the message board (and modified Word.Basic to Word.Application) and read the WebUtil manual and reviewed my set-up. Any suggestions are much appreciated.

I'm not sure about 10G, but for 9ids this is definitely wrong (see famous page 6 of 49 WebUtil Manual). On 9ids you have to add the virtual directory in orion-web.xml only, not in forms90.conf. On 9ias it is vice verca.
Hope this helps

Migration 10.1.2 - 10.1.3, error:: no ocijdbc10 in java.library.path

Hi,
I'm using Jdev 10.1.3, and my problem is the following one:
In my connection definition, that ORACLE_JDBC_TYPE is oci8 and when i try to conenct to BD, it occurs:
java.lang.UnsatisfiedLinkError: no ocijdbc10 in java.library.path
I've Oracle Client 9i and 8i, i've used each of them, but it doesn'nt work
I've drivers,jar, dll of client 10, becuase i supposse that it is that application need,
and i copy them in jdbc/lib of Oracle client(8i and 9i) and in jDev 10.1.3, but it doesn`t work.
The files are :
jars:: classes12.jar and ojdbc14.jar
dll ::oci.dll,ocijdbc10.dll, ociw32.dll,orannzsbb10.dll,oraocci10.dll and oraociei10.dll
Is there other path else where i should copy this jars,dllls?
Could we help me?
Thanks.

I am not familiar with Mac OS, but there are two things I can think of that you can check:
- This is trivial, and you probably did that: ist libocijdbc10.dylib in /usr/local/oracle/instantclient10_1 ?
- Could it be that Java is 32-bit and libocijdbc10.dylib is 64-bit or vice versa?
Yours,
Laurenz Albe

I have a portal module Component, in this i have a class wich extends the AbstractPortalApplicatin and in the doContent i include a jsp wich i have written. In this JSP i need some logic. Cause the logic I need here is not only used by this component i want to outsource the class wich does the work.
So I created a java component in wich i wrote my class. Created 2 public parts, an api for build time and a sda public part.
After that i createt a j2ee libary dc, in wich I add the public sda part from the java component. The Api is only for Build Time of the portal Component.
In the portalapp.xml I created a private sharing reference to the j2ee library component. But the class cannot be resolved. I really don't know what i have done wrong....

I figured out that you need to move the folder over to the shared section or share every folder in you folder structure above the one you need to share!!!

Could not find agent library on the library path or in the local directory

Hi all,
I'm trying to write a jvmti agent that write any information in a mysql db. I've written a simple agent that work correctly and now I'll try to insert the mysqlpp library in my agent:
1) I've added #include <mysql++.h>
2) and I've added mysqlpp::Connection      conn(false); (global variable)
I've modify my Makefile and the compiler and linker work correctly but when I test the agent the VM says "Could not find agent library on the library path or in the local directory"

Did you make sure your library (call it x) starts is named libx.so (atleast, on linux, possibly libx.dll on windows, not sure)? It will not load otherwise, and you must specify -agentlib:x (rather than saying libx.so). Yes, it is "funny" how it gives the same uninformative error message for a wide variety of errors. It will also give you this same error message if there are still unresolved symbols upon loading your library (which would be my second guess).

How do I create a runtime library reference from a J2EE library DC?

I've created a J2EE library DC that references some classes in an already deployed library. The referenced jar file has been correctly deployed, as it's successfully used by some other components. I can build the DC, since I've created created a compile-time reference to the local copy of the target jar file.
Unfortunately, I can't figure out how to create a runtime reference from my J2EE library to the already deployed library - there just doesn't appear to be any place to put the reference, at least using a gui-based function in NWDS. Unlike WebDynpro, which has a 'references' configuration option, J2EE lib's don't appear to have anything similar.
Where/How can I do this?
BTW, the Visual Administrator function 'ClassLoader Viewer ' is a very handy tool for diagnosing ClassDefNotFoundError errors....

Hello Ken,
well it seems to be not a trivial thing.
1) Build your library DC.
2) Create folder "server" in root DC folder "_comp".
3) Extract provider.xml from generated SDA file to "server" folder.
4) Add references in provider.xml:
    <references>
      <reference type="library" strength="weak">
        sapxmltoolkit
      </reference>
      <reference type="library" strength="weak">
        com.sap.lcr.api.cimclient
      </reference>
      <reference type="service" strength="weak">
        tc~sec~securestorage~service
      </reference>
    </references>
5) Rebuild DC. Deploy.
6) Enjoy!

How can i find what the java.library.path is?? urgent

Hi,
I have an unsatisfiedlinkerror and the message is no jicmp in java.library.path. can anyone tell me how to do System.out.println and the path???
This is very urgent so anyhelp would be gratefully recieved
Thanks
Vanessa

I have an unsatisfiedlinkerror and the message is no
jicmp in java.library.path.
can anyone tell me how to
do System.out.println and the path???System.getProperty() will retrieve the Java-defined system properties. You can use the following code to determine the available values:
public static void main( String [] args ) {
java.util.Properties p = System.getProperties();
java.util.Enumeration keys = p.keys();
while( keys.hasMoreElements() ) {
System.out.println( keys.nextElement() );

How to pass java.library.path as a VM argument in JNLP file

I jave a jar file containing reference to sqljdbc4.jar as I am using JDBC to talk with SQL Server. It works fine through eclipse IDE when I give the fillowing VM Argument
-Djava.library.path=C:\Users\reddys2\Downloads\sqljdbc_4.0\enu\auth\x86. Without this I get the "error message" saying that "failed to load sqljdbc_auth.dll

Thanks for the pointer. Question that I have is I am referencing sqljdbc4.jar in my application, which in turn using sqljdbc_auth.dll.
Which one should i refernce through <nativelib>. Is it sqljdbc4.jar or sqljdbc_auth.dll.
have added the following line to the .jnlp.
<nativelib href="sqljdbc4.jar"/>
But still it is complaining on sqljdbc_audth.dll. If it is sqljdbc_auth.dll, can I use <nativelib> to pass it.
In that case does it need to be signed?. If so,
Is it possible to sign .dll using 'jarsigner'?.

How to set runtime references in J2EE library DC's

Hi,
I'm building an custom logon module. This is well described in
http://help.sap.com/saphelp_nw04/helpdata/en/46/3ce9402f3f8031e10000000a1550b0/content.htm
I created the following DC:
1. simple java project DC that contains the login module class
2. J2EE library DC that will act as the deployable component.
The part "Make reference to the Security Provider service of the J2EE Engine." (2b) is where i get stumped:
http://help.sap.com/saphelp_nw04/helpdata/en/bf/93d84072378031e10000000a1550b0/content.htm
The example adds the reference direct to the provider.xml. I don't have that option when I develop the library as a DC.
It seems that while EAR file DC's allow the adding of runtime library references via the application-j2ee.xml file, it seems that is not possible for J2EE library DCs.
Specifically, I'm trying to get the follwing entry into the provider.xml:
<references>
<reference provider-name="sap.com" strength="weak" type="interface">security_api</reference>
I saw one workaround in the SDN where they suggest to extract the provider.xml from the SDA and manually
add the references but this isn't really an option in our case.
Should I be deploying 'normal' EAR files in this case ? Have I overlooked something ?
thanks
Michael

Hi,
talk about overlooking the obvious . . . The appropriate public part is present in com.sap_SAP-JEE_1.

Oracle Calendar - UnsatisfiedLinkError: no csdkjni in java.library.path

Hi, all.
I deployed my test calendar application developed using Jdeveloper 10.1.3.0 (on Windows XP) to the Oracle 10.1.3. AS on a linux server, but the CalendarServer in on another installation (Collaboration Suite 10.1.2) on the same linux server.
When I try to executed the code that calls the calendar server I get this error:
500 Internal Server Error
javax.faces.el.EvaluationException: java.lang.UnsatisfiedLinkError: no csdkjni in java.library.path
I set the LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib:$ORACLE_HOME/ocal/lib on the collaboration suite 10.1.2 installation.
When I try to run the code on my Jdeveloper I get the same error:
java.lang.UnsatisfiedLinkError: no csdkjni in java.library.path
In my windows machine I create a folder where I put the dll's and jar files that came from the collaboration suite windows installation, but I get always the same error
This is the code:
try
Api.init("calendar.ini", "calendar.log");
catch(Api.StatusException e)
System.out.println("init returned status'" + e.getMessage() + "'");
System.exit (1);
Is my approach correct? Because if i'm developing on Windows and I need dll's files to connect to the calendar server on linux, but when I deploy the application to the linux server those dll's are useless and cannot be used. So am I missing something here? Do I need anything else to get this to work?
Best Regards,
Rui

1. Use 1 and only 1 of classes12.zip and ojbc14.jar; they have different versions of the same classes in them.
2. The Oracle OCI driver for JDBC uses .dll files or .so files from the Oracle client installation (as well as Oracle network configuration files, I think); most people use the thin driver instead to avoid this problem.
To use the thin driver, change your url, see here for details:
http://www.oracle.com/technology/tech/java/sqlj_jdbc/htdocs/jdbc_faq.htm#05_00
To stay with the OCI driver (not recommended), you need to have the appropriate Oracle client installation (or at least get the dlls or sos), and I think set additional environment variables, such as ORACLE_HOME and possibly LD_LIBRARY_PATH. I don't do this myself, so I can't give much more advice.

How to refer to J2EE library server component from a web service?

Hi,
I need help! I created a web service and it worked fine. However, I started having problems when I tried to use java classes from my deployable J2EE library server component. I got the NoClassDefFound error.
I tried to include the library DC in the Used DC list and put the reference of it in the web service deployment descriptor xml (application.xml and application-j2ee-engine.xml), but it did not work.
How do I refer and use java classes from my deployable J2EE library at run time from my web service application? What should I do?
Thanks,
Giavinh Pham

I would like to clarify more about the web service project. I created a Java DC project and converted it into a web service as the SAP manual instructions. It worked fine by itself, but I now want to use some of my classes that I deployed as a J2EE library server component.
It was compiled and built when I refer to my J2EE library server component DC in the UsedDC. It was deployed fine as well. However, it broke when I tested the web service calls. The class declarations and usage from the J2EE server component could not be found (NoClassDefFound error.)
I thought it was because I did not have an application-j2ee-engine.xml in my META-INF folder so I created one and referred to the library in xml as type library and reference 'strong'. I built and deployed again. It still did not work.
I examined the EAR and noticed that there were two parts of the EAR. One is the WSAR archive file that contains the META-INF folder from my project and other web service assemblies. The other part is the META-INF folder generated by the SAP NetWeaver IDE.
The strange thing was that SAP NetWeaver IDE generated an application-j2ee-engine.xml without any reference to my J2EE library server component. However, the nested application-j2ee-engine.xml in the WSAR archive file did contain the info.
Since I cannot control the application-j2ee-engine.xml generated by SAP NetWeaver IDE, what should I do? Is it the cause for my problem?
Please advice, anyone?
