Java.lang.UnsatisfiedLinkError: when called from a jar file
I have a class that calls a custom dll file. If I dont package the class files and set my system PATH to the location of the DLL then the VM is able to find the dll and load it successfully.
However, when I package the class files into a jar file, I get "java.lang.UnsatisfiedLinkError: NetworkAdapters" eventhough the system PATH is set to the correct location.
I have also tried to packaging the dll with the class files but this has not made any difference.
Library is called from Java as follows:
static {
System.loadLibrary("NetworkAdapters");
When packaged the classes files exist in the following sub directories com\instem\hci\adapters
Any help appreciated.
Is it an executable Jar file?
The the DLL needs to sit in the same folders as the Jar itself.
(works for us).

Java.lang.UnsatisfiedLinkError when calling native function
I got exception as
java.lang.UnsatisfiedLinkError: no rvjs11 in java.library.path
Do I need any addtional setting?You need to make sure that the native library is in your "dynamic
library search path". You typically set this using an environment
variable (e.g., PATH on Windows, LD_LIBRARY_PATH on most Unix variants
except HP-UX and AIX, SHLIB_PATH on HP-UX, or LIBPATH on AIX).
Hope this helps,

Another question, I used a iplanet web server as a proxy server with a
cluster of two weblogic servers pluged in, although I set
weblogic.properties to round-robin, however, when I run a fibonacci servlet,
it does not do the round-robin. It always go to one machine for a lot of
times. Any idea?
Thank you for your help.

May i presume that your cluster is configured on a shared file system?.
I have seen this problem only if you cluster is configured on different machines
and if the directory structure is not identical.
let us know..

Multicast socket receive error: java.lang.RuntimeException: I/O error opening JAR file
I received Multicast socket receive error when I tried to restart the weblogic cluster in our pre-prod box.
The error message I received lkie this:
Multicast socket receive error: java.lang.RuntimeException: I/O error opening JAR file from file:/vol01/sites/vinlkup/site/versionc/local_classes/VIN/DeliveryTypeLookupEJB.jar
Yuping,
What release of WLS w/ service pack are you using? Make sure, if you are using a non-shared file system, to have the same absolute paths to your application on your file systems.

Java.lang.RuntimeException : I/O error opening JAR file
Hi,
Cluster configuration : 2 NT boxes WLS5.1(SP6). On one m/c weblogic
is installed on drive C:\ and on another m/c weblogic is installed on drive D:\.
i.e. all jars are at two place m/c 1 : c:\weblogic\myserver\*.jar
m/c 2 : d:\weblogic \myserver\*.jar
When servers startup successfully, error is coming :
on the console of m/c 1 :
java.lang.RuntimeException : I/O error opening JAR file from
file:/d:/weblogic/myserver/eb_arn.jar
on the console of m/c 2 :
java.lang.RuntimeException : I/O error opening JAR file from
file:/c:/weblogic/myserver/eb_arn.jar
When both the weblgoic servers are installed on two machines and
on same drive(c:\), this error is not coming.
i.e. all jars are at two place m/c 1 : c:\weblogic\myserver\*.jar
m/c 2 : c:\weblogic \myserver\*.jar
Regards,
Jitendra Kumar.
Jitendra,
This looks like a bug. Please approach support.

Java.lang.UnsatisfiedLinkError when loading libaries
Hi,
I coded an ejb, in which I want to call funtionality coming from a dll via JNI.
In order to achieve it I copied the libary 'XXX.dll' to the windows directory system32
and call in my ejb : System.loadLibary("XXX").
The following exception occured:
javax.ejb.EJBException: nested exception is: java.lang.RuntimeException: java.lang.UnsatisfiedLinkError: no XXX in java.library.path
Can anybody help me by saying
1) where to put the .dll and what path to set in calling System.loadLibary(...)
3) or even where and how to set the java.libary.path variable (Instance Template via configtool?)
Honour and points are garanteed.
JensHi,
Check This,
File f = new File("C:");
System.out.println(f + " \t" + f.exists());
f = new File(f, "sampleDLL2");
System.out.println(f + " \t" + f.exists());
System.load( f.toString() );
When the library can not be found, you get a java.lang.UnsatisfiedLinkError with the message "no library in java.library.path". To solve this, move the library in one of the directories specified by java.library.path or alter the property so that it points to the directory containing your library. You can print this property with the following code:
1: System.out.println(System.getProperty("java.library.path"));
Another possibility when things do not work is when the DLL can be found, but the methods can not. A DLL exports functions according to specific names an calling conventions. When your compiler is not configured the right way your methods may get anther name than they should be. To solve this, you should include the header file generated by javah and configure your compiler the right way.
Thanks,

Java.lang.UnsatisfiedLinkError when trying create a session to a topic.
I've tried the Oracle Streams messaging example here:
http://docs.oracle.com/cd/B28359_01/server.111/b28420/aq_demo.htm#i100786
But when trying to connect using java and oci I'm getting this
Exception in thread "main" java.lang.UnsatisfiedLinkError: oracle.jms.AQjmsSession.ociinit([JIIZS)J
This is the very simple code :
TopicConnectionFactory factory = (TopicConnectionFactory) oracle.jms.AQjmsFactory.getTopicConnectionFactory("localhost","orcl",1521,"oci8");
TopicConnection conn = factory.createTopicConnection("strmadmin","strmadmin");
TopicSession sess = conn.createTopicSession(true, Session.CLIENT_ACKNOWLEDGE);
What do do ?
I assume this has something to do with wrong dll being used ..
The server is 11g 11.2.0.1.0 - 64bit Production and java is 1.6 on Win 7Is it an executable Jar file?
The the DLL needs to sit in the same folders as the Jar itself.
(works for us). -

Problem parsing XML with schema when extracted from a jar file
I am having a problem parsing XML with a schema, both of which are extracted from a jar file. I am using using ZipFile to get InputStream objects for the appropriate ZipEntry objects in the jar file. My XML is encrypted so I decrypt it to a temporary file. I am then attempting to parse the temporary file with the schema using DocumentBuilder.parse.
I get the following exception:
org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element '<root element name>'
This was all working OK before I jarred everything (i.e. when I was using standalone files, rather than InputStreams retrieved from a jar).
I have output the retrieved XML to a file and compared it with my original source and they are identical.
I am baffled because the nature of the exception suggests that the schema has been read and parsed correctly but the XML file is not parsing against the schema.
Any suggestions?
The code is as follows:
public void open(File input) throws IOException, CSLXMLException {
InputStream schema = ZipFileHandler.getResourceAsStream("<jar file name>", "<schema resource name>");
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = null;
try {
factory.setNamespaceAware(true);
factory.setValidating(true);
factory.setAttribute(JAXP_SCHEMA_LANGUAGE, W3C_XML_SCHEMA);
factory.setAttribute(JAXP_SCHEMA_SOURCE, schema);
builder = factory.newDocumentBuilder();
builder.setErrorHandler(new CSLXMLParseHandler());
} catch (Exception builderException) {
throw new CSLXMLException("Error setting up SAX: " + builderException.toString());
Document document = null;
try {
document = builder.parse(input);
} catch (SAXException parseException) {
throw new CSLXMLException(parseException.toString());
}I was originally using getSystemResource, which worked fine until I jarred the application. The problem appears to be that resources returned from a jar file cannot be used in the same way as resources returned directly from the file system. You have to use the ZipFile class (or its JarFile subclass) to locate the ZipEntry in the jar file and then use ZipFile.getInputStream(ZipEntry) to convert this to an InputStream. I have seen example code where an InputStream is used for the JAXP_SCHEMA_SOURCE attribute but, for some reason, this did not work with the InputStream returned by ZipFile.getInputStream. Like you, I have also seen examples that use a URL but they appear to be URL's that point to a file not URL's that point to an entry in a jar file.
Maybe there is another way around this but writing to a file works and I set use File.deleteOnExit() to ensure things are tidied afterwards. -
Java.lang.ClassCastException when calling webservice stub from oracle DB
Hello everyone,
Because i need to get familliar with calling java webservices from an oracle database, i followed the following example
(http://www.oracle.com/technology/products/jdev/howtos/10g/WS_DBCallout/DBCalloutWS_HowTo.htm),
which included installing the SOAP client stack to the database (in the sys schema), grant the right permissions to the SYS user, developing a simple Helloworld webservice with jdeveloper 10.1.2, generating a Webservice stub and deploying a static method of this stub to the database.
All of this worked just fine, but when i want to call the webservice from oracle by invoking the deployed function, i get a java.lang.ClassCastException.
The complete stacktrace lists as follows:
v_Return = foutje: java.lang.ClassCastExceptionnulljava.lang.ClassCastException
at org.apache.soap.rpc.RPCMessage.serializeParams(RPCMessage.java:323)
at org.apache.soap.rpc.RPCMessage.marshall(RPCMessage.java:305)

at org.apache.soap.rpc.Call.invoke(Call.java:261)
at test.HelloWorldServiceStub.sayHello(HelloWorldServiceStub.java:82)
I debugged the WebServiceStub and noticed that the call.invoke method crashes. This is weird beacuse when i use System.out.println on the parameter is works just fine. so you would think it is a string.
Moreover, if i invoke the webservice from the endpoint or even when im debugging the stub locally it all works just fine.
Can someone plzzzzzz help me with this because i spend the whole day looking for an answer and im getting crazy!!!!!
Thanx al lot guys,
Kim
PS or could the problem be in the database instead of the webservice?????????

Kim ZeevaardersI think that it's going wrong because i did not install the right SOAP client stack.
In the HowTo is specified what JAR files are to be loaded in the database (from %JDEV_HOME), but it states that it has only been tested on a Oracle 9.2 database. I'm using Oracle10g. Maybe that's the reason that im getting this classcast exception...
Can anybody tell me what the right .JAR files are that have to be loaded into database when working with Oracle 10g?
Many thx in advance!

Java.lang.OutOfMemoryError when calling invokeMethod from CO
Hi All,
We are developing some custom pages using OA. All the pages were working properly utill yestarday and all of of a sudden I started getting java.lang.OutOfMemoryError error in my local Jdeveloper.I have not installed any new software or any upgrade between now and then, and there has been no changes to my application either. I even tried running this page standalone. I uninstalled Jdeveloper and reinstalled it again still the same. When I copy the code from AM into my CO it works fine. What could be causing the issue ?

at fpi.oracle.apps.xbol.gwo.webui.GWOOrderHeaderCO.processRequest(GWOOrderHeaderCO.java:126)Thanks for taking my query.
Here is the code from fpi.oracle.apps.xbol.gwo.webui.GWOOrderHeaderCO where the exception originated.. this is not just with this CO but in all the CO. This code is exactly the same as in the PO Tutorial. Also I could not locate the option to set the JVM memory parameter in Project setting. I have set the Java heap size -mx512m which I believe is what you wanted me to do.
OAApplicationModule am = pageContext.getApplicationModule(webBean);
Serializable[] parameters = { pageContext.getParameter("headerId") };
boolean rowFound = ((Boolean)am.invokeMethod("init", parameters)).booleanValue();
Here is the complete stack..

Java.lang.NullPointerException when calling getServletContext
Hi All,
When calling getServletContext from my servlet, i'm getting the following exception to my web client:
HTTP Status 500 -
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
exception
java.lang.NullPointerException
javax.servlet.GenericServlet.getServletContext(GenericServlet.java:159)
amdocs.checklist.UserPage.service(UserPage.java:126)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
amdocs.checklist.LoginFilter.doFilter(LoginFilter.java:65)
note The full stack trace of the root cause is available in the Apache Tomcat/5.0.27 logs.
My code is:
ServletContext sc = getServletContext();
RequestDispatcher rd = getServletContext().getRequestDispatcher("/Header");
rd.include(request, response);
It couldn't pass the call of getServletContext, Any idea why?
Thanks.I haven't looked at the source yet, but I remember the api specs talking about the init(ServletConfig) method being called by the container.
The servlet will the set up it's references to objects (eg. the ServletContext) and calls the init() method.
So, if you override the init(ServletConfig) method the references will never be set up, and you will get null calling getServletContext().
So always use the init() method for any initialization of servlets. -

weblogic.properties to round-robin, however, when I run a fibonacci servlet,
it does not do the round-robin. It always go to one machine for a lot of
times. Any idea?
Thank you for your help.

[ Solution ]
The class mentioned in the error message is in rm-pdrl.jar, which should be in your libs/2.0 directory. There may be a conflict between this jar and something in libs/1.5. Please try moving libs/2.0 before libs/1.5 in your classpath and see if that resolves the issue.hi Arie,
thanks for the tip ;-), I was using application id which was already use in my htmldb installation. I changed the id in the f105.sql to something which was not used and it went through fine.
We often run htmldb imports through sqlplus because when running it through web site it too often fails with timeout. When import is done through the web site I believe htmldb does the id modification automatically but in sqlplus that obviously won't happen hence we need to do it manually before running the script. If we don't change it import will fail as the workspace with the id mentioned in the sql script does not exist. Like you said might not be supported ....but it still works fine... :-)
thanks for your help.
