Paul,
In answer to your questions:
o Is the class CompanyList.class, or it's jar file, located
in the correct directory? <jetspeed_home>/WEB-INF/classes/... or
<jetspeed_home>/WEB-INF/lib
The classes are copied with a batch file to
C:\Apache\tomcat\webapps\jetspeed\WEB-INF\classes, my batch file:
ECHO Copying classes to C:\Apache\tomcat\webapps\jetspeed\WEB-INF\classes
copy *.class C:\Apache\tomcat\webapps\jetspeed\WEB-INF\classes\*.class
All classes are available.
o Based on the stacktrace, where did the exception occur?
I copy the relevant parts from my classes:
First, CompanyList.java
{
writer.println("CompanyList.getCompanyList: Logging in into IDES");
// Shown in my private logfile
// Log in into IDES
order.logIn (user);
// Create the BAPI
writer.println("CompanyList.getCompanyList: creating function " +
bapi); // Shown in my private logfile
order.createFunction (bapi);
// Get the company list
writer.println("CompanyList.getCompanyList: getting
COMPANYCODE_LIST"); // NOT SHOWN
tableArray = order.getTableAsString("COMPANYCODE_LIST");
// Finish with closing the connection to IDES
order.closeClient();
// Change tableArray to a HTML formatted string
StringBuffer buffer = new StringBuffer();
int length = tableArray.length;
for (int i = 0; i < length; i++)
{
buffer.append(tableArray[i] + "<br>");
}
return buffer.toString();
}
Next: Order.java
private JCO.Client client;
public void logIn (User user)
{
write ("Order.logIn: logging in user " + user.getUser() ); // Shown
in my private logger
try
{
client = JCO.createClient(user.getLoginParams() );
write ("Order.logIn: connecting" ); // NOT SHOWN
client.connect();
// And create the repository
createRepository();
}
catch (Exception exception)
{
write ("Exception: " + exception.getMessage() +
"Order.logIn()");
closeClient ("Exception: " + exception.getMessage(),
"Order.logIn()");
System.exit(1);
}
}
The relevant parts in my private logger:
CompanyList.ConcreteElement: creating order
Order.<init>: constructed
CompanyList.ConcreteElement: creating StringElement
CompanyList.ConcreteElement: getting company list
CompanyList.getCompanyList: Logging in into IDES
Order.logIn: logging in user mbergijk
EOF
By the way, as a stand alone application, using (almost) the same code,
everything works. Of course, almost is the dangerous word in this sentence.
So, the original code of Order.java (from the application that worked):
public void logIn (User user) throws Exception
{
try
{
client = JCO.createClient(user.getLoginParams() );
client.connect();
// And create the repository
createRepository();
}
catch (Exception exception) {
closeClient ("Exception: " + exception.getMessage(),
"Order.logIn()");
}
}
o Do the demo portlets work?
Yes. See the following copy of my Jetspeed portals page for the turbine
user:
Company list
org.apache.turbine.util.TurbineException: Error rendering Velocity
template: /controls/html/jetspeed.vm: Invocation of method 'getContent'
in class CompanyList threw exception class java.lang.UnsatisfiedLinkError
CMG Stock Quote
CMG stock price: CMGStockQuote.getQuote: Error opening socket:
soaptest.activestate.com
Hello User
Hello Michel! Currently the following portals are available:
None! Check back later
Note: Error opening socket is probably caused by me working behind a
firewall. This is not a pressing problem. First let me fix this
native-language problem. Then start the firewall problem in another thread.
The HelloUser portlet works as expected.
The JCO.Client class is situated in jCO.jar, placed in
C:\Apache\tomcat\webapps\jetspeed\WEB-INF\lib. When I try to rename this jar
file while Jetspeed is running, I get a share violation. This means that the
jCO.jar file is in use while Jetspeed is running. From this I must conclude
Jetspeed is capable of finding the jCO.jar file, and can use it.
Conclusion:
I still think Jetspeed cannot find my DLL's in C:\WINNT\system32. These
DLL's are used by jCO.jar when connecting to SAP.
Based on my inclusions, I hope someone can shed some light on this problem.
Michel

Michel,
From the log, I see the following error:
Invocation of method 'getContent' in class CompanyList threw exception
class java.lang.UnsatisfiedLinkError
This tells me the problem is in your code, not Jetspeed's.
Places to look:
o Based on the stacktrace, where did the exception occur?
o Is the class CompanyList.class, or it's jar file, located
in the correct directory? <jetspeed_home>/WEB-INF/classes/... or
<jetspeed_home>/WEB-INF/lib
o Do the demo portlets work?
