Broaden your horizons a bit from Java+Struts with MySQL on Win7
64-bit... This is an error message from the ODBC system. It is _not_
coming from Struts. It is _not_ coming from MySQL. It was present on
64-bit versions of Windows prior to Win 7.
- The MSDN forums have some info on installing 32-bit ODBC drivers under
a 64-bit platform.
- The Tomcat guys probably have info on running Tomcat in a 64-bit JRE.
Your solution will likely lie in one of those two places.

Caught OgnlException while setting property 'imageServletUrl'
G'day,
I appear to have resolved this issue that I kept running into with the
Jasper Reports plugin...
If I have an action defined as:
WEB-INF/foo.jasper
${contentType}
dataSource
/servlets/image?image=
Using the Jasper Reports plugin that ships with S2 current, I get:
16:02:13,220 WARN [OgnlUtil] Caught OgnlException while setting
property 'imageServletUrl' on type
'org.apache.struts2.views.jasperreports.JasperReportsResult'.
java.lang.IllegalAccessException: Class ognl.OgnlRuntime can not access
a member of class
org.apache.struts2.views.jasperreports.JasperReportsResult with
modifiers "protected"
at sun.reflect.Reflection.ensureMemberAccess(Reflection.java:65)
at java.lang.reflect.Field.doSecurityCheck(Field.java:960)
at java.lang.reflect.Field.getFieldAccessor(Field.java:896)
at java.lang.reflect.Field.set(Field.java:657)
at ognl.OgnlRuntime.setFieldValue(OgnlRuntime.java:1140)
...
And the imageServletUrl param does not take effect.
The issue appears to be that all of the setters in JasperReportsResult
return a JasperReportsResult. The JavaBeans spec identifies that the
setter for a simple property must return void. As a result,
BeanInfo.getPropertyDescriptors won't see these setters as write methods
for properties. With the other props in this class, that's not a
problem - since they don't have getters, we don't get any
propertyDescriptors for the properties, and proceed to look for methods
individually (OgnlRuntime.java:1296). For imageServletUrl, however,
there _is_ a valid getter. BeanInfo sees this as a read-only prop and
returns a property descriptor for it, showing exactly that. Back in
OGNL code, we see that we got a PropertyDescriptor, and don't bother
asking for all methods. getSetMethod says "I don't have a set method,"
so OGNL eventually tries to just poke the field, resulting in the above
error because the field is protected.
Solution: modify the setters in JasperReportsResult to return void.
This has been confirmed to fix the above problem.

And I was wrong :/// could U tell me what`s "static instatiate"? I`m search in google, but i don`t find answer... This`s connotated with getInstanceOf method? Please, give me an example. Regards, C. Java does not do static instantiation of objects like C++ / C# [?]. Java does support static instantiation of primitives (obviously). Perhaps you were confused when Paul said "First I'd say ditch the static references..." What he meant here was, you had a static member (private static int currentAmount = 0;) and two static methods (public static void setCurrentAmount(int _currentAmount) and public static int getCurrentAmount()). This is clearly not what you want. A static member is shared by all instances of the class. A static method cannot manipulate instance variables. Now, seeing what you did with your recent code, you did correctly remove "static" from the member variable and methods. As Dave Newton pointed out, the error given by the container is almost definitely because you are trying to call a method on a variable that is not instantiated. Either in the constructor of Settings, or in the declaration of the ac1,ac2,ac3 member variables, you need st like: ac1=new Account(); ac2=new Account(); ... before you call ac1.setCurrentAmount. I would suggest that you take a look at some of the Java primers / intro OO courses available. PK - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Parsed contentType in Stream result type, JR plugin
G'day, Don't know if this has been mentioned before, but 'twould be useful to be able to get StreamResult to take the contentType param as an index into the value stack (I have an action that determines content type based on user input). Worked around this by extending StreamResult and overriding doExecute(), but perhaps this is a more common occurrence. Also, it would be useful if the JR plugin were to check if the param datasource is an instance of JRDataSource and if so, use it directly, rather than instantiating a ValueStackDataSource on it. I'm working with a bunch of Reports built to XML data sources, and clearly, the ValueStackDataSource doesn't play nicely with the XPath expressions in the JRFields. Worked around this by building all the JR stuff directly into the action class. PK - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
