RE: (Updated) Problem with < and > as parameter value
Now it is even more confusing.
I have a service method with two parameters called systemType and systemID. Both have type String.
If I supply 'a<aa' as value to systemType I get an parser error, but NOT to systemID parameter. I have tried all possible combinations and systemID is always parsed correctly but systemType is never parsed correctly.
Does this make any sense?
Regards,

The problem is that soap and xerces/jaxp does a good job parsing '<' to '<', but not so good job translating back.
On clinet side an instance of Parameter class is created with 'good<day' as value and used in Call.invoke(). Before reaching my service classes on server side soap and xerces/jaxp parses '<' back to '<' and sees this as a problem character instead of just sending the string 'good<day' to my service class.

Here is what I've recently worked with to translate special characters into
proper XML:
charater/sequence entity reference(replacement)
& &
]]> ]]>
< <
Unfortunately, I don't recall where the source of it is from. Good Luck!

When using TcpTunnelGUI to monitor XML messages transfer I can see that the
sent string "good<day" (as parameter value to a service method) in the XML
message has the text "good<day".
After that Xerces/JAXP converts/serializes this to a String, but something
goes wrong and a error message is returned to SOAP client.
I have tested this on Xerces 1.2.3 and 1.4.3, and JAXP 1.1. All versions
gives error but different error messages.
Bug in XML perser/String serializer or encoding setting?
Anyone know where to find specifivcation for which characters are possible
to user as request parameter values.

The "<" character shold be converted to "<" and
">" to ">". This should be done in the SOAP library,
I think...
