External jar for jspdynpage

what are the external jar to be added to the jspdynpage project?
I have this error:
The import com.sapportals.htmlb cannot be resolved
The import com.sapportals.portal.htmlb cannot be resolved
DynPage cannot be resolved (or is not a valid return type) for the method getPage
JSPDynPage cannot be resolved or is not a valid superclass
PageException cannot be resolved (or is not an exception type) for the method doProcessBeforeOutput
The method setJspName(String) is undefined for the type Concorsi.ConcorsiDynPage
Thanks!!!

Hi
The following jar files are for jspdynpage portal component,
htmlb.jar
com.sap.portal.htmlb_api.jar
com.sap.portal.htmlb_bridge.jar
servlet.jar
You can find the jar files in the portal sever itself.
Thanks,

Including External JARs for Java Application in OC4J

Hi Experts,
Here is my requirement.
I have developed my Java application using Tomcat Server & Eclipse. In my application I have used some External JARs & imported the classes in my JSP.
Now that I'm using OC4J Server instead of Tomcat I'v no clue as to where I have copy these External JARs for my application to work.
I have installed OBIEE-Client which includes OC4J server. The path where I have placed my application is as below
*"C:\OracleBI\oc4j_bi\j2ee\home\default-web-app"*
If I run my application the server does not import the classes in the JSP which we include using Import statement using JSP tags (*ex* - <%@ page import = "org.apache.commons.fileupload.*"%>).
This is the location which I found, where I need to put my Java-J2EE application. This OC4J_BI comes with OBIEE.
Kindly help me out on where to place these External JARs exact location in OC4J.
Also let me know if I have to alter any configuration/xml file (if so pls specify the file name & its location).
Thanks in advance,
Venky

You can either include the external libraries in the application, by placing them into WEB-INF/lib, or you can import them into the server as "shared libraries", normally you'd use the "enterprise manager" application to do this. Having loaded a shared library you then add it to the classpath when you're deploying the application.

DownloadService.loadResource for external jars for 1.6.0-19+

First, be kind with my english, i'm french (nobody's perfect...)
I have a JNLP into which i declare a signed jar resource main.jar. This application retreive at execution a list of signed jar names (+a.jar, b.jar+...) that i dynamically load on my need through DownloadService.loadResource. My a.jar, b.jar are cached and it rules! But if i made a new main.jar, a.jar and b.jar, and deploy them on my server, here what's happend:
- main.jar is tested for modification date on server (thanks to "If-Modified-Since" HTTP header), cache date is before this date, so JWS update main.jar by downloading this new main.jar. This is the behaviour described into specs and it is perfect for me!
- but for others resources (a.jar, b.jar) i was excpected the same behaviour but JWS does not seems to check for modification date. So a.jar and b.jar are not updated.
So my first question: Is there a way to tell to DownloadService.loadResource to check for modification date? i could deal with jar version but this basic date checking was great for me...
Except this cache minor problem, external jar download works just fine except i get the warning security problem [Mixing Signed and Unsigned Code |http://java.sun.com/javase/6/docs/technotes/guides/jweb/mixed_code.html].
All my jars are signed with the same certificate, so i was a bit confused.
Anyway, i follow indications and put the Trusted-Only: true attribut into the manifest of main.jar.
But it leads to this exception:
java.lang.SecurityException: Trusted-Only loader attempted to load sandboxed resource from http://monserveur/a.jar

 at my.package.a$5.run(a.java:348)
 at java.lang.Thread.run(Unknown Source)I found some posts that deal with similar problems but it does not give me a working solution. The difference seems to be the fact that i load external jars (not defined into JNLP).
My JNLP is validated though JaNeLA.
I cannot set a.jar, b.jar as resources into jnlp because i retreive their location during execution...
My JNLP also declare:
<security>
 <all-permissions/>
</security>I think i'm a bit confused with the sandbox notion and the Trusted-Only: true attribut of the manifest. I also tried to add it to a.jar, b.jar and not main.jar but vainly. I also tried to set it on all jars but it does not work better.
Is there a way to load external jar without having the Mixing Signed and Unsigned Code warning popup? What do i not well understand?
Sorry to be so chatty...
Thanks in advanced for any answer.

So, I finally succed in finding a solution.
But this solution seems perhaps a barbarian way to solve my problem but it works.
The idea (as far as i understand) is that when you define "all-permission" into JNLP file, then these permission are granted for JNLP ClassLoader. When you load external jar through DownloadService.loadResource, then another classloader is used. It seems that this classloader does not inherit security policy from JNLP ClassLoader.
My solution is to define my own policy:
Policy.setPolicy(getAllPermissionPolicy());
 * @return a {@link Policy} with all permission granted
 private Policy getAllPermissionPolicy()
 Policy policy = new Policy() {
 private PermissionCollection m_permissionCollection;
 @Override
 public PermissionCollection getPermissions(CodeSource p_codesource)
 return getAllPermissionCollection();
 @Override
 public PermissionCollection getPermissions(ProtectionDomain p_domain)
 return getAllPermissionCollection();
 * @return an AllPermissionCollection
 private PermissionCollection getAllPermissionCollection()
 if (m_permissionCollection == null)
 m_permissionCollection = new AllPermission().newPermissionCollection();
 m_permissionCollection.add(new AllPermission());
 return m_permissionCollection;
 return policy;
 }For sure, you can decline this with permission you need. Here, all permission are allowed.
I'm not quite satisfied because it's seems to be a barbarian style solution. But for now, it fits my uses => no warning popup!
If anybody has a more proper way to deal with such an issue, i'll be glad to hear it!
Hope it helps.

Permissions to external Jar for reading-writing on a file

hi all,
I explain my situation.
I ' ve made an open source project similar to plpdf using jasper report libraries and others.
My project, which works perfectly in a java jre, have some problems in Oracle Aurora jvm.
I use the Reflection technique to load the classes from their libraries.
For this i use this class :
{color:#993300}import java.io.File;
import java.io.IOException;
import java.lang.reflect.Constructor;
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;

Constructor cons = classe.getConstructor(parametersClasses);
return cons.newInstance(parameters);
public static Object executeMethod(Object obj,Class objClass,String methodName,Object [] parameters,Class [] parametersClasses) throws IllegalAccessException, IllegalArgumentException, InvocationTargetException, NoSuchMethodException {
Method method = objClass.getDeclaredMethod(methodName,parametersClasses);
method.setAccessible(true);
return method.invoke(obj, parameters);
public static void addJarLibrary(String s) throws MalformedURLException, IOException{ addJarLibrary(new File(s)); }
public static void addJarLibrary(File f) throws MalformedURLException, IOException{ addJarLibrary(f.toURI().toURL()); }
public static void addJarLibrary(URL url) throws IOException{
URLClassLoader urlsysloader = null;
urlsysloader = (URLClassLoader) sysloader;
try { executeMethod(urlsysloader,URLClassLoader.class,"addURL",new Object[]url,new Class[]{URL.class});
} catch (Throwable t) { t.printStackTrace(); throw new IOException("Error, could not add "+url.getPath()+" to system classloader"); }
public static void addJarLibraries(String libDir) throws IOException {
File directory = null;
directory = new File(libDir);
if(directory.isDirectory()){
JarFilter filter = new JarFilter();
File[] jarLibraries = directory.listFiles(filter);
for(int i=0;i<jarLibraries.length;i++){ addJarLibrary(jarLibraries{color}{color:#993300});
} else { throw new IOException(libDir+" is not a Directory !"); }
{color}
I gave all the permissions as dba to allow java to access files, etc. etc
{color:#993300}Begin
dbms_java.grant_permission( 'NEOGEO', 'SYS:java.lang.RuntimePermission', 'accessDeclaredMembers', '' );
dbms_java.grant_permission( 'NEOGEO', 'SYS:java.lang.reflect.ReflectPermission', 'suppressAccessChecks', '' );
end;
{color}
Then when I try to call a class library that attempts to access a file residing in the file-system i recive an exception.
This is an example of code that call a class and execute one methods.

jCompileManager = jcmClass.newInstance();
// compilazione del report
jReport = Utility.executeMethod(jCompileManager,jcmClass,"compileReport",params,paramsClasses);
return jReport;
{color}
this is the exception :

The problem i think is that i have to give the permission for input and output on files to an external jar-library .
I don't know how i can resolve this problem ....
Do you have any suggestions? 

Hi,
the problem with grant_permission is, that this can be done for a schema or a role - not for a ProtectionDomain as you need.
Some on this forum claim that it is possible to control the SecurityManager by the java.policy file in OH/javavm/lib/security. You should try to put something like this in this file (create it if it doesn’t exist)
grant codeBase "file:/<your codebase>" {
permission java.security.<your privilege>;
Unfortunately this doesn't worked for me in 11.1.0.6.0.
What you could try if you don't find other solution is to extend or write your own (not recommended) SecurityManager.
see http://download.oracle.com/docs/cd/B28359_01/java.111/b31225/chten.htm#BABJBJGE
To simple see if your application runs without security you can try the NullSecurityManager.
see http://java.sun.com/developer/onlineTraining/Security/Fundamentals/magercises/SecurityManager/help.html
compile and load the class in your schema and activate it with
System.setSecurityManager(new NullSecurityManager());
This is for sure not a solution for a productive system.

Java Mapping - add external jar for runtime use

Hi,
I have implemented a java mapping which executes an XSLT transformation on the input XML. This way I can control (I hope) what XSLT processor is used, as I want to use the SAXON XSLT processor. The java mapping executes fine locally in NWDS.
But when executed runtime I get the following error in default_trace and the message stops in Integration Engine:
javax.xml.transform.TransformerFactoryConfigurationError: Provider net.sf.saxon.TransformerFactoryImpl not found
In my java mapping I have set the following:
System.setProperty("javax.xml.transform.TransformerFactory", "net.sf.saxon.TransformerFactoryImpl");
The TransformerFactoryImpl class is implemented in saxon9.jar.
Where do I store the saxon9.jar on the server so that it will find it during execution?
Any hints are most welcome!
Br,
Kenneth

Hi Kenneth,
                      First of all java mapping procedure has the capacity to transform XML using SAX or DOM parser directly. I am not sure as to why you need "SAXON XSLT processor" for the purpose.
                       Now coming to your question "Where do I store the saxon9.jar on the server so that it will find it during execution?"
In NWDS import the jar file saxon9.jar within your package, where you have written the source code. This you can do using File->import ->(ZIP or jar file).    Before you import slect the package or folder where you want to import the jar file. Once jar file import is complete execute the code once, see if its running properly. Then choose file->export and select all *.java and *.class files in your package. Save this under one filename say package.jar.
Finally import this jar file in PI server by usual methods.
Hope this solves your problem
regards
Anupam

Getting error while calling external Jars in BPEL by using Java embedding activity in soa 12c

Hi,
I am trying to use an external Jars for the business logic implementation. Here I need to pass XML as input and
and I expect the "Password " field has to be return.
Following are the steps I have followed:
1) Created a java project with sample class and added the external jars into the project "Libraries &Classpath".
2) Created a jar file out of it.
3) Created a BPEL project with Java Embedding.
4)Wrote the java code in java embedding activity.
4) Added the above created jar file to the BPEL project's lib/jar and added in SCA-INF/lib project folder as well.
5) Imported the package with the class as in the jar (e.g <bpelx:exec
import="pkg.testInterface"/>)
6) Deploy the BPEL project.
while deploying the SOA build is sucessful but my depoyment is incomplete.
error:
advices will be great....
Regards,
Dilip

Hi,
Can you confirm if the BPEL Version is 1.1 or 2.0.
If you are using BPEL 2.0 you need to import the required jar/class file as:
<import importtype="http://schemas.oracle.com/bpel/extension/java" location="pkg.testInterface"/>
For BPEL 1.1 the syntax to import other jar/class file is:
<bpelx:exec import="pkg.testInterface"/>
If you import the classes in the correct format you will not face any deployment error.

How to use one external jar (SDK) for several apps in WTK?

Hi,
I have one external jar (SDK) I use for developing J2ME applications.
Every time I have no choice but to copy this JAR (SDK) into my current application lib directory.
I am building a family of MIDlets that I dont want to put into just one huge JAR but rather to have several JAR files for each application.
In C world I need only to tell the linker where it should pickup ".so" or ".lib" file.
Is any way to do the same with WTK? Or any other J2ME development tool?
Thanks in advance,
Andrew

Link to wtk2.5 beta has been posted to this forum
while ago. It's worth to try it It is MSA1.0
compliant. It has many new JSRs.TomTom,
Thanks again.
I tested the WTK2.5BETA and here I ahve strange fact. My application works perfectly on WTK2.1, WTK2.2 WTK2.3 BETA but it crashes with a very weird message on WTK2.5BETA
Method............: 22482ac 'com/tinyline/app/SVGEventQueue.handleEvent (virtual)'

So I thought, OK it was compiled under WTK2.1 may it was the reason of crash.
I took sources and compile them under WTK2.5 BETA. I came up with the same result - crash.

How to call external jar files in EJB project for CE

Hi,
I would be thankful if someone could help me with this -
I need to call the external jar files into my EJB project - Here is what I have done and am getting runtime exception as -
java.lang.RuntimeException: java.lang.NoClassDefFoundError: com/glance/pdf/pt/PTDoc
1. Created a EJB project" HelloWorld " using Java perspective in NWDS 7.1 called with client as HelloWorldClient and EAR project as HelloWorldEAR.
2. Am working on HelloWorld project (1st one).
3. In my code I am instantiating a class which is a class in one of the external jar file that I need to refer in my project.
4. I have set the Java Build path but it works only for the compile time and fails during runtime.
5. Have read I need to create external library DC and refer in my project "HelloWorld".
Can anyone help me with exact steps what needs to be done - during creation of external library project and then for my "HelloWorld" EJB project. How would I be able to reference or set the external library project in my EJB project?
Looking forward to hear from experts.
Thanks,
Shiv

Hi Edson,
I tried it , but it still gives me runtime exception.
javax.ejb.EJBException: nested exception is: java.lang.RuntimeException: java.lang.NoClassDefFoundError: com/glance/pdf/pt/PTDoc
java.lang.RuntimeException: java.lang.NoClassDefFoundError: com/glance/pdf/pt/PTDoc
Steps I performed are -
1. Created a library project and created 2 Public parts "Compilation" and "Assembly"
2. Build the library project.
Now in my EJB project using Project Explorer - set the classpath and added both compilation jar and assembly jar files.
This is how the classpath entries for external library looks like -
<classpathentry kind="lib" path="/LocalDevelopmentLocalDevelopmentexternallibrarypdftoolsforwatermarkingdemo.sap.com/gen/default/public/WatermarkAssembly/lib/java/demo.sap.comexternallibrarypdftoolsforwatermarking~WatermarkAssembly.jar"/>
<classpathentry kind="lib" path="/LocalDevelopmentLocalDevelopmentexternallibrarypdftoolsforwatermarkingdemo.sap.com/gen/default/public/WatermarkCompilation/lib/java/demo.sap.comexternallibrarypdftoolsforwatermarking~WatermarkCompilation.jar"/>
I have also added the jar files I used in my external library project as "User Library" from Java Build Path . I dont do it , then the code fails during compilation itself.

External jars in Web Dynpro for Java CE 7.1.1

Hi there,
Can you give me some guidance for including external jars in Web Dynpro for Java (CE 7.1.1)?
I vainly tried for some hours now to get my external jars running in the new version of web dynpro (part fo Composition Environment 7.1.1).
The routines described in some other threads didn't help me. For example, in CE 7.1.1 there's no DC Metadata that would allow me to add an external library.
FYI, in the error message during build it simply says the package is not found.
My error is javac ERROR: D:\test.jdi\LocalDevelopment\DCs\demo.sap.com\retail\_comp\src\packages\com\sap\demo\retail\javafiles\DomParser.java:12: package com.sap.semprom.retail.sc does not exist

How to add external jars when deploying webapp via worksop for wls 9.2

While attempting to deploy my web application using Workshop for WLS 9.2, WLS complains it is unavailable to resolve references to a 3rd party JAR(tomhawk.jar) which is being referenced by the JSPs. I have added the JAR via the J2EE module dependancy tab in workshop but that does not seem to be helping the deployment.
If i build the web application outside workshop and include the tomhawk.jar in the WEB-INF/lib folder of the deployed WAR file, the app works fine.
I have attempted to copy the tomhawk.jar into the <domain>/lib folder and restart the weblogic server. But this does not seem to help resolve the references.
Any clues on how i could achieve iterative deployments via workshop for WLS 9.2 pickup references to external JARs being referenced by the JSPs.
Thanks
Ramdas

Raj,
Thanks for your suggestion. The link that you sent out was useful. I was actually able to get the webapp to resolve its references to the 3rd party classes by adding the tomhawk.jar as an external jar via the "build path" property for the web project. I tested this by running the app in the WLS instance hosted by workshop and looks like the JAR from the build path gets somehow referenced during run time too. Not sure how this works?
Thanks
Ramdas

Help need in Adding External jar files.

Hi all,
Iam developing ADF application using JDEV 11.1.1.3.0.
I need to move files from one directory to another so i have used external jar "commons-io-1.4.jar" file.
i did this by going to the project properties -->Libraries and Classpath -->Add Library
added the jat file.
In java class i have used the function
File.copyFileToDirectory(reQueueFile, TargetLocation,false);
it was working fine when i tried in IntegratedWeblogic server but when i deploy in Standalone Weblogic server its not getting the jar file.
Its throwing me the exception
javax.el.ELException: java.lang.NoSuchMethodError: org/apache/commons/io/FileUtils.moveFileToDirectory(Ljava/io/File;Ljava/io/File;Z)V

Please let me know is there a way of adding the lib to the project.
Regards,
Suresh kumar.k

First you should check that the library has the checkbox 'Deploy by default' is checked for your library.
The you open the project properties of the view controller project, select Deployments, edit the deployment descriptor. Select the Node 'File Groups'->'WEB-INF/lib'->'Contributors'. this should give you a list of libraries your project uses. Check if your library has the checkbox checked (is selected fro deployment). If it's not checked, set it.
This should include the library.

How to include external jars - URGENT...

Hi:
I am using Eclipse for development.
My application uses some external jars.
This step is simple in Eclipse, one simply indicates where the jars are to the IDE.
However, when I make an executable JAR file from my project, those external JARs are not included.
So when I run my program, everything is fine until the parts that uses the external JARs.
Does anyone know how to include them outside of Eclipse platform?
I am going to see my client in an hour and of course I can't bring my source and install an Eclipse at my client's computer to show them my demo...
please help... thanx...

You add those external jars to the classpath or the jars classpath if you're running the program from a jar. Or put the external jar to JAVA_HOME\lib\ext (IIRC)

How to bundle the MDM jars (External jars)in a DC?
How to create the Public Parts in the DC for the added MDM External Jars?
How to use the above DC in the EJB DC?
Basically, I am looking for a step by step procedure,
to add external jars in a DC.
And to use the above DC in a EJB DC.
Any assistance in this regard is appreciated.

You should not reference the MDM jar files by setting classpath directly. For setting references to it from your EJB DCs , you will have to create a DC of type "External Library". Deploy this DC also before your EJBs are deployed. You will then have to create a public part for this DC and the reference the public part from the DC metadata of the EJB DC ie set the Used DC list of EJB DC to the public part of the ext lib. You will get info about this in NDS help as well on help.sap.com

Hi Vanita,
open your project in nwds > right click on the project > click on properties option from the menu > click on java build path from the left-side navigation of the window > and click on libraries in the right side tab > here you'll get a button called add external jars > clicking to this, will open browser window to select a jar file.
