Does anyone know how to install an EJB in the deploy directory and access it from the default-app? How do you set the _context variable? What, specifically, goes into an ejb-jar.xml file? What , specifically, goes into a deploy.properties file?
Here is the structure of my ejb.jar file: C:\projects\mathexp>jar cvf mathexp_ejb.jar ejbeans/*.class META-INF/ejb-jar.xml added manifest adding: ejbeans/MathExp.class(in = 350) (out= 219)(deflated 37%) adding: ejbeans/MathExpBean.class(in = 4712) (out= 2395)(deflated 49%) adding: ejbeans/MathExpHome.class(in = 407) (out= 244)(deflated 40%) adding: ejbeans/MathExpPK.class(in = 753) (out= 452)(deflated 39%) adding: META-INF/ejb-jar.xml(in = 890) (out= 372)(deflated 58%) Here is my ejb-jar.xml file: <?xml version="1.0"?> <!DOCTYPE ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD EnterpriseJavaBeans 1.1//EN" "http://java.sun.com/j2ee/dtds/ejb-jar_1_1.dtd";> <ejb-jar> <description>Mathematical Expression Bean</description> <display-name>Mathematical Expression Bean</display-name> <enterprise-beans> <entity> <display-name>MathExpBean</display-name> <ejb-name>MathExpHome</ejb-name> <home>ejbeans.MathExpHome</home> <remote>ejbeans.MathExp</remote> <ejb-class>ejbeans.MathExpBean</ejb-class> <prim-key-class>ejbeans.MathExpPK</prim-key-class> <persistence-type>Bean</persistence-type> <reentrant>False</reentrant> <env-entry> <env-entry-name>ejb.allowedIdentities</env-entry-name> <env-entry-value>all</env-entry-value> </env-entry> </entity> </enterprise-beans> </ejb-jar> Here is my deploy.properties file: # #Tue Oct 23 16:21:51 CDT 2001 ejb.homeInterfaceClassName=ejbeans.MathExpHome ejb.enterpriseBeanClassName=ejbeans.MathExpBean orcl.ejipt.minFreeConnections=5 ejb.primaryKeyClassName=ejbeans.MathExpPK orcl.ejipt.sourceURL=jdbc\:oracle\:thin\:@127.0.0.1\:1521\:orcl ejb.ejipt.classServer.port=2323 ejipt.jdbcSources=orcl ejipt.logStackTrace=true orcl.ejipt.sourcePassword=maxalex orcl.ejipt.sourceDriverClassName=oracle.jdbc.driver.OracleDriver ejb.remoteInterfaceClassName=ejbeans.MathExp ejb.ejipt.home.port=2323 orcl.ejipt.maxConnections=30 orcl.ejipt.maxFreeConnections=10 orcl.ejipt.sourceUser=jack ejipt.ejbJars=mathexp_ejb.jar, ejb.ejipt.classServer.host=martin Here is my MathExpServlet: import java.io.*;
