Mike -- In your parameter value for setFirst, change java.lang.string to java.lang.String with a capital S for string. HTH, Gary
-----Original Message----- From: java400-l-bounces@xxxxxxxxxxxx [mailto:java400-l-bounces@xxxxxxxxxxxx] On Behalf Of Mike Pantzopoulos - (H/O) Sent: Monday, February 19, 2007 3:31 PM To: java400-l@xxxxxxxxxxxx Subject: Brick Wall I've reached a brick wall with a RPG to Java interface and was hoping that I might be able to get some assistance. I've tried to include all relevant code. It's just a self-tutorial exercise at this stage, and out java programmer has created the java. The class is in the correct IFS folder. It's the old RNX0301 problem and I'm getting nowhere as I'm never quite sure what other small, but fundamental piece of syntax (or understanding!) is missing. I have a test harness CL which sets the class path immediately before calling the RPG: CHGENVVAR ENVVAR(CLASSPATH) + VALUE('/java/leo/ibm-jaxrpc-client.jar:/jav+ a/leo/objectpoolimp.jar:/java/leo/xercesImp+ l.jar:/java/leo/xml-apis.jar:/java/leo/') I use debug to examine the CLASSPATH just before the failing RPG command, and it is correct. The class I am using is interfacing to the Active Directory so we can access various contact details using the iSeries user profile. Here is the start of the Class, and the one method I'm trying to access: package au.com.eigansvar.web.webservices.userdb.client; public class User { private java.lang.String department; private java.lang.String email; private boolean enabled; private java.lang.String fax; private java.lang.String firstName; private java.lang.String hphone; private java.lang.String hphone2; private java.lang.String jobTitle; private java.lang.String lastName; private java.lang.String mphone; private java.lang.String pager; private java.lang.String private_mphone; private java.lang.String state; private java.lang.String wphone; private byte[] sid; private java.lang.String ad_username; public User() { } public void setFirstName(java.lang.String firstName) { this.firstName = firstName; } When I look at the dump taken after the exception occurs, I can see the two objects: PROFILE OBJECT(*JAVA) java.lang.String: asanovl USER OBJECT(*JAVA) au.com.eigansvar.web.webservices.userdb.client.User: au.com.eigansvar.web.webservice s.userdb.client.User@65c31594 (By the way, what does the @65c31594 signify?) I presume their presence in the dump means that the two instantiations worked correctly? The RPG is as follows (minus comments): /copy qsysinc/qrpglesrc,jni D RunCmd PR 10I 0 ExtProc('system') D CmdString * Value D Options(*string) d newString PR O EXTPROC( *JAVA d : 'java.lang.String' d : *CONSTRUCTOR) * d CLASS(*JAVA : 'java.lang.String') d value 65535A CONST VARYING d newUser PR O EXTPROC(*JAVA d :'au.com.eigansvar.- d web.webservices.userdb.client.- d User' d : *CONSTRUCTOR) * d CLASS(*JAVA d :'au.com.eigansvar.- d web.webservices.userdb.client.- d User') d setFirst PR EXTPROC(*JAVA d :'au.com.eigansvar.- d web.webservices.userdb.client.- d User' d : 'setFirstName') d value O CLASS( *JAVA : 'java.lang.string') d CONST d User S O CLASS(*JAVA d :'au.com.eigansvar.- d web.webservices.userdb.client.- d User') * d profile S like(jstring) c eval profile= newString('asanovl') c eval user= newUser() c callp setFirst(user : profile) The program seems to instantiate profile and user correctly, but the last line fails with the dreaded RNX0301: Message . . . . : Java exception received when calling Java method. Cause . . . . . : RPG procedure JAVTST05 in program ANVDEV/JAVTST05 received Java exception "java.lang.NoSuchMethodError: setFirstName" when calling method "setFirstName" with signature "(Ljava.lang.string;)V" in class "au.com.eigansvar.web.webservices.userdb.client.User".
